Ok I did some further tweaking and got mine stable at 442-443 MH/s. 1000MHz/350Mhz, 68C with fan @ 60% (ambient temp is around 80F), case cover is on.  That's with 11.5.  With 11.6 I lose about 80 MH/s.

Have you tried going down to 335? A lot of people here (including me) have gotten the 5870 to 335 -333 without affecting hashing speed. What about voltage?

I'm mining at about 382 Mhash/sec with an HD 5870. In the ATI Catalyst Control Center, I've overclocked the GPU to 900 Mhz, and downclocked the memory to 900 Mhz. The fan is set at 75%, and the current temperature is 78 C with the side panel removed (I also have an nVidia GTX 580 running the miner in a slot right below it, so this drives the temperatures up).

Are there any other currently-maintained Windows apps out there for overclocking AMD GPUs, besides ATI Tray Tools? For some reason, ATI Tray Tools doesn't want to run with both AMD and nVidia hardware in one system, with both sets of drivers installed.

So Phönix would work better than diablominer?

I get 1267374/1256143 khash/sec using 3x 5870...

I'm on a 2006 mac pro running a XFX HD 5870 which I found on pricelover.com for around £110. Flashed the BIOS to make the card work in OS X. Left clock speeds and voltages as stock.

Get really bad speeds in OS X due to Apples crippled OpenCL implementation.. somewhere around 150mhash/sec last time I tried, although I hear its much better running OS X 10.7 (lion).

When booted into Windows 7 I get approx 350mhash/sec when left at stock settings.
If I overclock with MSI afterburner I can achieve 430Mhash/sec when clocking to 969/350.
The card crashes or becomes unstable (although it recovers without a reboot) if I clock GPU over 970.
Running most recent AMD drivers (11.6 I think) and phoenix with the Phatk kernal.

Similar results (430mhash/sec) when booted into Ubunutu, although I have to flash the bios to overclock out of the preset ranges as I don't believe there's an MSI Afterburner type app for linux?

Temps anywhere between 65ºC and 75ºC depending upon ambient temp.
I leave the side of the mac off and the fans appear to need to do less work to keep GPU and mac CPU cool, meaning less noise.

I'm running an Apple 5870 clocked to 1020/300, stock voltage, with MSI Afterburner running in Windows 7 on a MacPro

Temps 57C and fan at 60% - running Phoenix and phatk & getting 448Mhash/s for about 5 days now with no issues.

Update 4/25/11:  I switched over to the Phoenix miner 1.1, and now run at 421-423 mHash/sec on all of my 5870s.  Clock settings are 975/300, using 0.950 voltage.  They're running cooler, sucking less power, and running significantly faster with Phoenix!

Yeah..phoenix is definitely the way to go with the 5870's...I get 415Mh/s with settings of 940/305 temps around 65degC...they could probably do more..but I think it would be marginal for the extra juice/time tweaking/reduced lifespan required to achieve it..

My opinion is if you can get over 400-410 with your 5870's lock her in and ride it...it's not worth getting more (with present known methods).

My Gigabyte 5870 Super Overclock goes to 1000 easily, probably because it's non-reference, with an extra fan and higher quality bin they pulled it from. It's already factory overclocked to 950.  For everyone using 5870s, don't forget to knock your memory clock down to the sweet spot you find for hashing with your setup, somewhere between 300 and 400. A rule of thumb is GPU clock / 3 + 14, but I've seen it vary from person to person.

How do you manage 1000MHz, my many 5870 in ubuntu wont accept any clock setting over 900MHz, at which they are perfectly stable.

You use atiflash to read the bios and use Radeon Bios Editor to modified the clock rates.  Then reflash.  Limits?! We don't need no stinking limits.

I have 2x5870s. Running @970MHz, I get about 418MH/s per GPU using hashkill, running at 980MHz, I get about 426MH/s. No memory downclocking involved. Fan speed at 80 keeps them below 65C, anyway that kinda depends on ambient temperature.

Hey,
I'm sitting here with a Gigabyte 1GB 5870 and my temperature goes to 98° after 30 sec of mining. Fan is running 100% at 3600 RPM,

got about 300 mH/s which drops down to 200 after the card gets too hot. I have only one card installed, and no additional fans. stock cooling at all.

Board and CPU are sitting at ~ 41°C, no problems there.

Running Windows 7.

Would I ever get a decent temperature with an additional fan at the front bottom of my case or is my card somewhat damaged?

i'm getting 420MH/s per card - 930MHz core 300MHz memory bfi_int Vectors aggression=11 phatk kernel - phoenix miner
my problems is with the cooling as well. the top card can go as high as 100degrees C while to lower one stays at about 70C
my problem is with the spacing. i think i got 4mm between the cards. that changes today as I'm getting a different motherboard.

I'm getting 83C temps and 330Mhashes/sec on my Asus matrix 5870 2GB clocks @ 982/1245

Is that normal? Cause from reading here it doesn't seem like it is?

Pretty sure these cards just run hotter than normal even with the jet engine of a fan they have.
I'm currently running one at 427 Mhash/s and have a 2nd on the way for crossfire.  Temp is at 83C in an 29C degree room.  This is with the fan at 100% and the case open with a large window fan pointed at the card.  I'm thinking of taking the card apart and reapplying thermal compound.
Clocks are 990/600 set through the Catalyst Control Center.  I tried using the Asus itracker software but it causes more crashes than it's worth.
11.4 drivers with SDK 2.4 phoenix 1.5 phoenix rising 1.45 with aggression set to 14, VECTORS and WORKSIZE=128 phatk is checked and so is HD5xxx

ATI HD5870
Catalyst 11.5
SDK 2.4
975MHz core / 333MHz memory
1.250v (not sure how to change this lower, it automatically bumps up when I change core/memory freq)

Phoenix parameters: -u device=0 VECTORS BFI_INT AGGRESSION=14 WORKSIZE=256 -k phatk

430.xx MH/s, stable over the past 24+hrs
69-70C @ 50% fan speed with case-cover on, house A/C thermostat set at 78F

Everybody told me to try 300MHz for the memory and that kicked the MHz up quite a bit.  After a little experimenting I found the sweet spot to be 333MHz (using ATI GPU Tool) which increased the hash rate by about 6-8 MH/s over 300MHz memory clock on my system. YMMV.

hi guys,
I was just wondering how you manage to keep your cards this cool?!
I got two xfx 5870  running at 860/300 stock voltage and I can´t get the temperature down.
My temperature after a day of mining is between 83C - 86C the cards fans are working their asses of at 100%
How can that be? This is my current setup:

Maybe you got some tips?

Thank you!

my room is quite cold, and my case has space for a fan right over the gap between the two (looks like its similar spacing). Its not a very good fan and I might buy a better one, but right now, the cards run at about 75-80C on stock volts, but thats because I changed the fan speeds to be at around 60% (its in my bedroom, and I'd rather have it considerably quiter than a few degrees cooler).

the only thing you can do is to either do the same or get spacers.

Anyone running 2 x 5870 in crossfire in Windows 7? I can get them to run at 970 but I find that from time to time the system will BSOD, yet the temps are fine. Highest it ever reaches is 74c.

Is it possibly the crossfire setup being the cause? The reason why I'm using a crossfire setup is because it's running on Windows and I haven't got any dummy plugs.

1x5870 + 970/300 on Windows gets me 412 mh/s in phoenix.

I'm currently running the crossfire setup at 950/300 at the moment to see if this prevents the BSOD.

The highest I can push my XFX 5870 is ~372-375Mhash at around 985 Core. Anything higher and it starts freezing and crashing.

Well done Smiley
Wow what model number? I have a ZNFC XFX 5870.  Stock settings I get about 358-360MHash/s.  Overclock to 925 with 1.163 (Highest stable. Can get 930 but locks up after several hours of use) and I get just over 400MHash/s

Artic Cooling Accelero Xtreme Heatink - get 56c displayIO temperature (62 memory and 60 shader).
