Topic: AMD R9 290X? - page 4. (Read 108823 times)

If your using the computer for normal use and mining in the background you should be setting intensity to 'd' and tweaking --gpu-dyninterval. Otherwise your either gonna get lag(intensity to high), or be missing out on hastrate(to low). d will dynamically adjust intensity depending on how demanding what ever else you are doing is.

I have a question for anyone about this screenshot. I am newish to scrypt mining so this has been on my mind for a few weeks now.

I have R9 290 cards and R9 280x cards. The 280x cards never seem to have stale shares. I often get stale shares and job not found on my 290 cards. Why is that? Can I do anything to avoid this? Does it matter? If anyone could chime in that would be much appreciated.

Don't mix nvidia and amd on the same system! :p

That's asking for trouble...I'd reccomend uninstalling all gpu drivers and starting from scratch, AMD only. 13.12+sdk 2.9 haven been great for me.

Also, you can't crossfire 290x and 7970. Different architecture. No need for cables or xfire enabled anyway...

2 290's running hot but fast

Hi everybody, I am using GeForce 560 ti and Radeon 290x on my motherboard, and I have Radeon HD 7970. Nothing working when I put 7970 and 290 x on crossfire. I have on 290 990 khs and on GeForce 560 ti 160 khs. Why I can't use 290x and 7970?

I just made a quick test on my testbench, which has only a sempon 145.

using the 280x at 740 settings gives little lag, even flash videos on youtube run almost smooth, altough I would not prefer watching it that way.
minimum hashing was 690.

using a 290 in the same setup lost me 280 khash to get the same feel.

so my recommendation against a 290(x) in a dual-use pc stands.

of course dual-use is never ideal (i never said that!), but I think old tahiti architecture is better suited than hawaii.





"You say you experience no lag at all between 280x at 100%? BS. I've got over 4 rigs with multiple 280x cards in them now, and even Linux shows lag and screen artifacts with 280x's at 100%."

first, I did not say that, and second, it is almost true!
I run my 280x not at max settings which is around 758kH, but that is way too loud/hot/unstable for productive environment; but I run them at ~738/744kH which is the efficiency sweet spot for that perticular card.

running everyday things I experience hardly any lag. that does not mean, that I don't notice any lag, but it is small enough to be not worse than a "4 year old laptop with 2 browser windows open" (that is metaphorical!)
lag is small enough that I can do my work without being botherd (and don't tell me i am not sensitive!)

using the pc drops the kH to ~700ish, most of the time it is around 710, but it goes down to 680 under load.

I cannot say the same for a 290 setup. lag is always way greater when running the cards at 80-90%. bringing them down so that lag becomes acceptable i could almost idle them. which is not great at all

thus: in my experice the older architecture is better suited for dual-use/background mining.
if you experience otherwise... good for you

You say you experience no lag at all between 280x at 100%? BS. I've got over 4 rigs with multiple 280x cards in them now, and even Linux shows lag and screen artifacts with 280x's at 100%.

I experience about the same lag on my 290x at I20 as I do with 280x cards at I13 G2. Of course I have halfway decent PCs, one is a 3930k w 2 280x, and the 290x is a 4770k.

So no, I still don't see your point. For normal PC use, mining totally f'cks it up. Enjoy browsing the internet with crippled hardware acceleration and love the driver crashes if a flash applet just happens to load. I do it with noscrypt, but I don't like it and generally just turn the primary 280x off in CGminer, restarting it when I'm finished. I think I'm up to 13 days on one cgminer window now?

 

that is the setting for the 280x that I use in my desktop system.
I was pointing at my original statement, that a 290(x) needs high intensity to work and and that is not compatible with lagfree dual use!

a 280x/7970 or 7950 is very compatible with using the pc regularly, a 290(x) is not! using settings that are lagfree, I don't get more than 500kH on a 290...

when I use my desktop system for office/surfing, etc. I loose 30-40kHash at I13, but am almost lagfree.


before I used the 280x I used a 7950 in my desktop system and got similar results. ~700 kH max and loosing some when working.




seems some of you are missing my point... (setup for dual-use/background mining)

700 KH/s with a 7950 @ Intensity 13?
You need a damn nice card and crazy overclock for that.
Even with 1.1-1.2 Ghz Core and 1.5 Ghz Mem you don't get that rates with intensity 17-20. Wth Intensity 13 you are below 400 KH/s.

Try

-g 1 -w 512 --lookup-gap 2 --thread-concurrency 24550 -I 17 --gpu-fan 50 --gpu-engine 947 --gpu-memclock 1250 --expiry 10 --scan-time 5

should get you 810 stable...when you close CGminer don't use the inbuilt menu (it will crash - on Win 8.1 anyway), instead just close it like you would any other window.

i am using 7950s and 280x in systems and have them running at there max hashrate 700/740 at intensity 13 and I get hardly any lack.
of course if I use video intensive software or utilize the system 100% my hashrate goes down, but at optimal settings I can still use the pc almost lagg free.

on my 290 systems I cannot do that.

so my statement is very right! if you want to mine "in the background", why use a 290(x)?

@pontiacg5
now tell me where that is wrong?

In what world does not pushing ANY graphics card to 100% not lag the computer? Think hard, because I've plenty of first hand experience to make you look silly.

If you want to get as much hashing power as possible yet still be able to use the computer you are going to have to settle for less than optimum hashrates for the card. The 290x has a lot more room to still make a decent hashrate, yet still leave the computer useable. Cheap shitty cards don't.

The reason you likely can't get the --thread-concurrency 33792 setting to take is because you aren't using the proper setx flags. Unless you use GPU_USE_SYNC_OBJECTS 1 and GPU_MAX_ALLOC_PERCENT 100 the highest TC you will likely ever get started (without the out of memory errors) is 2816.

Open up a command prompt as an administrator and try and run this...

setx GPU_USE_SYNC_OBJECTS 1

and

setx GPU_MAX_ALLOC_PERCENT 100

You should see "success" after each commad. If not, try adding "-" in front of setx (-setx.)

If that works, before restarting the computer try starting mining with that TC. It's likely that I20 will do a lot less damage to your computer's useability when you are running at an optimal TC. You will never see 900+ hashrates without a high TC and Intensity.

My 290x likes 1000-1025 engine and 1500 memeory for 937kh/s. Under air it likes 1025 engine clock, but under water and 60c temps lets 1002 engine push the same 930kh/s.

if you want to use your computer in parallel, why did you go with a 290(x)? you could have gone with any "older" card and would have got better results for less money....
I don't get what some people around here do...


since 290/290x seem to require hi intensities (at the moment), there is no real other option for you...

Thanks for sharing, but this setting (--thread-concurrency 33792) will prevent my card from running with a -4 error

And intensity 20 will prevent the computer from being useable ...

I'm getting 930 Kh/s with my single R9 290X.  Check out my blog post where I go over all the settings I used:  http://thecryptomaniac.blogspot.com/2013/12/mining-with-radeon-r9-290x-how-to-get.html

My R9 290X won't start with such settings ... so I'm stuck @ 620 KH/s with the following command line : --intensity 14 -g 1 --shaders 2816 --lookup-gap 2 --no-submit-stale

Any advices ?

what kind of PSU do you have? Corsair 850 AX will be enough?

Some news for custom card from asus and it's not just a custom cooler:

Doh, DVI-D, not DVI-I.

You are right, my bad!
