Topic: HD7770 & HD7750 mining thread (Read 49894 times)

Just wanted to tell you guys I managed to get stable hashrate @ 205 K/Hash on my ASUS 7770 directCU 1GB

edit: this one https://www.asus.com/Graphics_Cards/HD7770DC1GD5/

I tweaked the settings everywhere I could without flashing any bios or anything.

settings with most impact:

Engineclock: 960 Mhz
Memoryclock: 1450 Mhz
vddc: 1.225v
thread-concurrency : 8192
Intensity: 16 or 17...


Full config report:

I have a SAPPHIRE HD 7750 1GB GDDR5 LOW PROFILE (ATI chipset). I bought it because it fits in my computer and has low power drain. I run the graphics at stock GPU clock 800 MHz, Mem clock 1125 MHz. I don't overclock because the card is already running at 80C and 99% activity. I use Windows 7 Pro 64 bit 4 Gb RAM with CGWatcher v1.3.4.6 with CGMiner 3.7.2. Catalyst Version is 13.9 or 13.12, PCI Express 2.0 x16.

I run off Multipool  stratum+tcp://pool1.us.multipool.us:7777.

Intensity is 11, any higher and I get HW errors. Worksize doesn't seem to make any difference. In scrypt I get around 140 kH/s and Work Utility is from 110/m to 150/m. Efficiency is around 114%.
Power drain is 45.6W (max 55W TDP).

Here are the settings:
"scrypt" : true,
"verbose" : true,
"auto-fan" : true,
"auto-gpu" : true,
"gpu-threads" : "2",
"gpu-fan" : "33-70",
"intensity" : "11",
"temp-target" : "80",
"temp-overheat" : "85",
"temp-cutoff" : "95",
"temp-hysteresis" : "3",
"thread-concurrency" : "2048",
"submit-threads" : "64"

Sometimes I blank thread-concurrency and use shaders 512 instead. The GPU doesn't seem to get as hot with thread-concurrency 2048.

Also I use my graphics card for playing games, I'm a bit weird that way.


Edit: I've found higher performance settings:

"scrypt" : true,
"verbose" : true,
"auto-fan" : true,
"auto-gpu" : true,
"gpu-threads" : "2",
"gpu-fan" : "25-70",
"gpu-engine" : "300-920"
"gpu-powertune" : "20"
"intensity" : "11",
"temp-target" : "75",
"temp-overheat" : "85",
"temp-cutoff" : "95",
"temp-hysteresis" : "3",
"thread-concurrency" : "2048",
"submit-threads" : "64"

gpu-fan is limited to 70% speed to avoid wearing out the fan.
gpu-engine can be set higher than 920, but the card and/or computer crashes. The computer must be re-booted before playing games. Otherwise the game crashes.
temp-target can be set to 80 during winter, but the card will overheat at 80 during summer. It will need to be set back to 75 during summer.
gpu-powertune is set to +20 to allow the card to use more power.

Any programs that are using a lot of CPU time will slow down the mining programs.

Now in scrypt I get around 162 kH/s and WU is around 140.

At these settings the card is temp limiting to control heat. The card can go faster if the ambient air temp is lower. 164 kH/s seems to be its peak performance.

Taking the lid off the computer case drops the temp by about 5 degrees. It's cost-effective to do mining during winter because it helps to heat the room.

How many and what cards you using?

7770 is a overpowered model of 7750, I think you may be wrong as I am using 7750 for some further havesting.

Total power consumption for the tower is 220w, at idle is 76w. Each 7770 card consumes 72w when mining.

https://bitcointalksearch.org/topic/7750-miningmaybe-not-so-meh-after-all-64368

This chaps getting ~110 @ I = 12, not really on par with the 7770 tbh.

Not bad, but depends what you paid for them - I picked one up for £25 and the other for £50. That's cheaper than one 7750.. 

About the same, 135-140.  Close enough considering how little the 7750 cost.  Plus mine's a low profile card so fits in a smaller case.

Same hashes?   

A single 7770 on intensity 12 manages 150 for me (so not flat out), with two I average 300. What does the 7750 average on same intensity?

7750 is a good little card, does about the same hashes as a 7770, but a lot cooler and quieter (and no need for a PCI-E power cable). 

It looks like the 7750 is more reasonable than 7770.

I may be able to perform the 150Mh/s as I am able to perform 150Khash/s scrypt mining.

It looks like you have configured something wrong, I only use 895/1295 for it.

Thread resurrection. 

Would have posted sooner but the rules put me off, anyway.. What power draw is everyone averaging for their system with these cards and the intensity values?

I have 2x 7770 and during the heat wave a few weeks back the room would be unbearably hot.

200 out of a 7770 is pretty good.  Make sure the VRMs stay cool though.

I see, cheers for the information. That explains why the card was so cheap Ah well at least it's a boost for my mining! I'm using Asus GPU tweak for clocking and it's pretty good.

Here's why:
http://www.gpureview.com/show_cards.php?card1=675&card2=638

The 6970 has a lot more shader processors, and overall is more than twice the card as the 7770.

You are doing good with the 7770.  Mine I can't overclock more than about 5% before the driver starts crashing, even with tweaking the heck out of it to allow for more power, etc, in MSI Afterburner.  :-(

So I usually get about 180-190 MH/s.

Recently bought a HD 7770 card, but I never get more than max 200 MH/s, and that's after I've clocked it. I've got another card, HD6970 or 6950 I think and it gets almost twice the speed. What's up with that? Any tips for me to make it run faster? Currently using the flags worksize=128 VECTORS FASTLOOP AGGRESSION=10 WORKSIZE=128 -f 5.

https://bitcointalksearch.org/topic/underclocking-memory-speeds-correctly-on-7xxx-series-cards-with-afterburner-111891

Crazy - I'm running AB too but it only lets me set 150 below like the other dude said.  How do I get it lower?  or is it b/c I have the 7750?

I'm running the ASUS HD 7750 900MHz overclocked to 1000/850 and I'm getting a steady 148.5 MH/s with 49% fan speed and 69 deg C temp

I'm running GUIminer with -v -f 10 -w 128

Its been running for about 2 days and I'm getting about 0.01 BTC/day plus the same in NMC

My http://www.amazon.com/gp/product/B0079XWPEK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1&tag=thelinactsho-20 Gets about 133.3 MH/s with bitminter on a core clock of 880 with any of the newer cataylsts I try on ubuntu 12.04.2+.

FWIW, I started playing with OCing today. I'm getting 144 off of my 7750 at 975/800, -v -f1 -w128
(edit: 146-147 @ 995/750. I think I'll let that run tonight, because I don't want to get crazy with this when I am not awake to monitor. I DO use this PC for other things most of the time, so I need to not blow up the card.)

how ?

hmm:

Sapphire Radeon HD 7750 Ultimate (fanless) 55W TDP

GuiMiner 2012-12-03 -v -w128 on Win7x64

No OC (800mhz / 1250 mem)

...

117mhash


DiabloMiner:

DiabloMiner-Windows.exe -v 1 -w 256

...

119mhash

DiabloMiner-Windows.exe -v 1 -w 128

...

121mhash

increase clock to 880mhz (+10%)

...

131mhash

Ah yes. I have my 7970 running undervolted at 1050/310 using MSI AB. I was running it at 1200/475 at stock volts, but it pulled too much power. He specifically stated that he was using CGMIner, which sets the card clocks using the built in AMD ADL, which is limited on clocking the memory to -150MHz below core. MSI AB uses unofficial overclocking methods, which are often not noob-friendly, both in the initial setup, and in everyday use.

Ah ok, glad you got it working. The lower memory will help with lower power and temps, but it's not exactly a powerhouse for mining. Glad I could help!

Sorry was a typo getting them round the wrong way.. I have set my 7750 at core clock 900... memory clock 400 I can get down to on MSI Afterburner

Still only runs at 121Mhash average.. but I suppose that all I gonna get out of the card, ty for all your help crazyates least now i using less power with a lower memory clock

not true...if you do the msi afterburner OC thing it'll let you set your mem down to 300...so they say but i'm running my 7970 at 1100core and 685mem...can't get it to get lower then that...the slider bar won't go back to the middle but oh well i'm happy with it

You set your core to 650, and your memory to 800? That is not what I recommended. Bitcoin mining is very calculation intensive, so it requires a high overclock, but it does not require a high memory speed. On my 5870, I ran it with a core OC of 975, and my memory was all the way down to 300. 7xxx cards cannot underclock their memory that low. 7xxx cards can only underclock their memory 150MHz below the core clock.

Thus, when you were running your core at 800, you want your memory at 650. If you're core is set to 650, your memory should be 500. See the pattern?

Ok ty I did not know this... i just assumed u needed to max out the clocks as much as possible... i have set mem clock to 900 and core to 650 and seem to be squeezing out a little extra on the hasrate... will see how it runs for a few hours and if there is any difference... but thank you again for the info and educating me

If you're setting your core to 800, you want your memory at 650. High memory does not translate into higher hasrate, it just means higher temps and higher power consumption.

Thanks for the replies... still can only average 121Mhash on this card... tried the setting you suggested, and played with worksize and intensity a little from the suggestions here https://en.bitcoin.it/wiki/Mining_hardware_comparison but looks like this is possibly the most i can squeeze out of this card for now it seems... set core clock to 800MHz and Memory Clock to 900MHz and power limit + 20% so everything up high... can go higher on core clock and memory clock but tends to crash the card

@FuzzyBear, try changing intensity to 7 and the kernel to diablo.  My 7750 @ 830/300 gets about 128 MH/s.  Overclocked to 950 MHz, it does 150 MH/s.

Hmmm any advice would be appreciated...

Friend gave me a HD7750 the other day...

Plugged it in motherboard on seperate computer away from my main 7970 rig...

I have installed all necessary drivers and opencl support drivers...

Fired up comp, detects GFX card (running the monitor from it)

open both GUIMiner and cgminer.. but both do not detect my GPU

any further points to try?? OS is XP as opposed to win 7.... could that be an issue as i just copied the mining software across from there?

Many thanks... and GTZ on Avlon releasing first ASICs!!

EDIT:

OK i got it working.... just upgraded to windows 7... much easier

only getting 110-120MHash/s on a 7750 using cgminer... config file looks like:

any advice on tweaks would be appreciated as its 2am and i need to sleep... i'll try different settings over the weekend and post if i get better and no-one replied

my HD7750 runs fine at 150 MHash/s

You still have to change the value in the config file irregardless, unless I'm been goofing up for the past 2 years.   

That's why I said IF. If you don't need the file, then you shouldn't get the no-sliders issue.

That's assuming you're using 2.2.2 or later.  2.2.1 or older include those files.

If you do that, and still can't underclock memory, download and place "atipdlxx.dll" into the MSI AB program folder.

Very nice purelithium.

As for lowering the memory, go into MSIAfterburner.cfg and change "UnofficialOverclockingMode = 0" to "UnofficialOverclockingMode = 2".  You should be able to lower it further.

My Sapphire ghz edition 7770(stock 1150) is running stable at 1300 core and 650mem(AB won't let me go lower for some reason) on stock voltage at 241 mhash/s on BFGMiner on win 7 64bit, using Diakgcn kernel. very impressed.

It would not increase hashrate dramatically.

I Got 2 7770 working at 1100 doing 180-200 MHash/s each one at 70C

did you guys make it working on a linux distro ? i cant install drivers make a black screen before install

Got my MSI 7750 in the mail today.

Gets about 125.5 Mh/s @ 830/1125 using DiabloMiner.  GPU temperatures are at 49°C with a fan speed of 46%.

136.1 Mh/s @ 900/800.  GPU temps reach 50°C with a fan speed of 46%.

Not bad for something that uses the PCIe slot for auxillary power.

Yeah it is idiots like you that think RMA is the universal solution that is driving up the GPU prices for EVERYONE else when the manufacturer has to take into consideration this variation of theft / revenue loss from people claiming DOA or RMA when they destroy card on purpose.

Once you OC you should have no warranty but AMD is too dumb to properly implement this so once you OC it is recorded in BIOS or something ... or at least that's how it should be done.

Just RMA it back to newegg and tell them I no know what happen. What's that you say? Overclocking? Me? Nawww

Got to 1300 MHz but had to push voltage to 1.28, which really isn't worth it anymore. Reverting back to 1200MHz @ stock

Well AMD has shrunk the line up a bit so we'll have to wait and see how the HD 7800 cards do and their prices.

It's probably going to be four months before AMD is putting out steady driver updates for GCN.

Next on Bitcoin talk, how to let all the magic smoke out of your components and turn them into doorstops. 

I hear ya  at least the MHs/Watt is alright I guess.. Maybe in a year when the price is around $110 they'll be a better option.. I'm hoping for some fairly serious kernel improvements as well, maybe slightly better drivers too, but you can't expect too much improvement in that field from AMD these days.

You could always try 1500MHz @1.4v lol, haven't tried pushing that hard yet 

I am working on my 7770 as we speak.  Getting very similar numbers OP is.  NOT happy at all.  Glad I kept all my new 5850s.

Sorry for the delay on this, the following is assumed when taking these measurements:

7770HD is GPU 3 in my system, with no monitor attached, I am assuming 5 watts idle board power (IBP) (supposedly 3 watts), thanks to AMD Zero Core
Memory is not under-clocked, I wasn't able to use ATI tray tools on this GPU since it is not GPU 0 or the same type of GPU as 0, 1125MHz GDDR5, you could probably shave off a few watts if you downlcoked it to 300.
165 Watts total system power idle, from the plug, measured with Kill-a-Watt
System is using an 80-plus bronze certified PSU

Drum roll please:
Stock voltage and clocks: 1,000MHz @ 1.175v, ~150MH/s using Phoenix 2.0 (Diablo is slightly faster) 165watts > 211 watts (rounded up .5 watts) + 5watt IBP = ~50 Watts, or 3MHs/Watt with current drivers and kernels
1250MHz @ 1.215v, 184MH/s using Phoenix 2.0 (Diablo is slightly faster) 165 Watts > 225 watts (rounded up 1 watt) + 5 watt IBP = ~65 watts, or 2.83MHs/Watt with current drivers and kernels.
Not too shabby if you can overlook the high $/MHs

Anyone who thinks these numbers are low, consider that with the architectural improvements, the graphics core consumes only slightly more power than the GDDR5 memory would under full load, hence the 80 watt TDP. I wonder if this card will boot without a 6 Pin PCIE connection..

Also note that even with a high fan speed (bought the XFX double fan edition) this card gets rather warm in my server rack with extremly good air flow, hotter than my shader unlocked 6950's do running at 920MHz 
Could it be the die simply dosen't have the surface area to dissipate that much heat into the heatsink? Industrial manufactured diamond-based heatsinks now plz!

you mean gcn. graphics core next.

Well, with my 5750 I can get about 190 Mhashes/sec at 890Mhz/0.98V/65C with cgminer 2.1.2.

What do you expect ?

It has got less shaders.

GCN shaders are not faster than VLIW5 shaders ...

 So, 7770 is 1.5 times slower than 5770?   What a waste of money on this junk.

There was a problem with earlier cgminer releases and the new 12.2 ATI driver release. This should be fixed in cgminer 2.2.7 so this should work with these cards.

I was able to get diablominer working! Stupid me, I had http:// in front of my pool URL, which was causing it not to be able to connect I guess, anyway:

Latest Diablominer as of 2/17/2012, 12.2 with bundled 2.6 SDK, Win7 64bit, clocked at 1230MHz: 183MH/s vs 181 MH/s Phoenix 2.0 with fine-tuned paramaters; will experement with differant paramaters later this evening, I'm pretty sure I can get more MH/s out of it, as diablo defaults to 256 worksize, which is not optimal for 7770. I'll bet I can get at least another 5MH/s out of it with -w 128. Still, I was hoping for 200-220 MH after a 20% OC, which is about what the 6770 gets  

Also, Dia is going to send me an updated kernel for Phoenix 2.0 which isn't available on github; I'm hoping that will work even better as Phoenix 2.0 is already getting almost as much as diablo. Will post results of this as well as power consumtion tests later this evening. Also going to try overvolting and higher OCs this evening too! @1230MHz atm at stock.

Here is you best option. Install the latest 12.2 drivers and use diablominer get the latest one updated yesterday. run with no flags that should do good. (maybe -w 128 might be faster) I have my 7970 on those settings getting 690Mhash each.

I tried diablo which started up on all four GPUs, even recognized the 7770 as Capeverde, but none of my GPUs started hasing, it just idled saying 0.00 MH/s..

cgminer wouldn't start either, saying failed to initialize GPU 0.. not sure how to configure that though really, tried going through this guide that had me install mingw32, and Microsoft SDK and a bunch of other steps, but I still couldn't get it so start..   sorry, still a noob at some of this.

Supposedly DiakGCN kernel with Phoenix works 99% as well as cgminer using diakgcn though, according to Dia who wrote the kernel for both miners.

Will try and post some power consumption rates later today.. I managed to get 1240MHz core on stock voltage though (1.17v), going to try and get 1300< on 1.2v

Hashing at 183MH/s @1230MHz using Phoenix 2.0 running OpenCL kernel.. Anybody have any idea why this kernel would result in better hashrate than diakgcn or phatk2 using the same miner?

Any power consumption numbers yet?

Try DiabloMiner and cgminer because they are the only ones to be working with 7XXX cards.

Report back if you can. Thank you !

7770 seems fairly different from 7970 though.. BFI_INT does not appear to be supported for one, and most kernels now have it enabled by default; I will try cgminer after I make something to eat  

EDIT: BFI_INT does work with 2.6 SDK bundled with 12.2 preview drivers, doesn't help much though.. Diablo started up but didn't start hashing.. maybe is was user error though, never used that before.. cgminer didn't start either but that was also probably me 

We bought ckolivas (the guy who does cgminer) a 7970 specifically so he could tune cgminer for the GCN architecture. He has been working on a kernel and helping Diapolo integrate his kernel into cgminer. I get my 7750 tomorrow, I'll post my results here, though I may do a detailed review thread as well.

Going to try them next; never used them before so I was trying to avoid them.. Dont need all the fancy overclocking and fan options cgminer has, and I don't like the idea of a Java miner..

EDIT: I made a mistake on my original post, I was actually running at 1100MHz when I got the origonal MH/s rate.. It's actually less at stock   only 131MH/s with Phoenix 1.7, and 149 MH/s Phoenix 2.0 when using the opencl kernel for some odd reason.. only good news is GPU is on auto fan and only 55*C at 1100MHz

149 MH/s at stock speed now: Phoenix 2.0 rc1, autoconfigure = enabled, VECTORS = true, BFI_INT = disabled, DiakGCN doesn't seem to work with Phoenix 2 atm

NOTE: autoconfigure slects opencl as the kernel, not phatk2. Not sure if this means anything to anyone since I get higher MH/s using this kernel, also I thought that kernel was only for use with CPUs.. strange I get higher MH/s with it..

Anyone tried Diablo or cgminer yet? Supposedly they have built in support for GCN, although I haven't tried them yet

So I figured I'd start an official mining thread for the Hd 77xx series..

Just got my first 7770 today, and I must say I'm less than impressed.. BFI_INT doesn't seem to be supported, as any miner that has it enabled, default or otherwise will just exit.

So far I have tried the DiakGCN kernel for Phoenix, as well as phatk and phatk2, tried using phoenix 1.7.4 (about to try with 2.0 rc1) and I get 131MH/s at 1000MHz, 9 aggression, vectors (just VECTORS, 2, 4 or 8 decrease performance), and worksize 128 (256 decreases slightly, and 64 makes no difference)

Using 12.2 drivers for 7700 series, SDK 2.6 (started at 2.5, read that 2.6 was better for GCN so I upgraded and it made no difference [fortunately it didn't seem to decrease my hash rate on my 6950, maybe due to the 12.2 drivers]) and Windows 7 64bit

Anybody who is able to get over 131.5MH/s at 1000MHz clock speed, PLEASE post all your specs, including miner, and the parameters fed to it.
