Post your 7970 Card info and Settings

[gateway]

Just thought I would try to start a thread where we could collect the a list of 7970's and what rate your pushing them. 

Card, Drivers, OS etc:

• Card Name:
• Card ID:
• Catalyst Driver:
• ASIC Quality (GPU-Z):
• AMD Stream SDK:
• OS:
• Voltage Unlocked:

OC Settings:

• Core GPU:
• Memory:
• Voltage
• Boost:

Miner Info:

• Miner:
• Config Options:
• Hash Rates:
• GPU Temp:

Screen shot if any..

Am I missing something?

Also your settings for your card should be running stable and not have to baby sit it please.

Ill go first:

Card, Drivers, OS etc:

• Card Name: Sapphire Radeon HD 7970 OC with Boost http://bit.ly/ZCHNVD
• Card ID: 11197-03-40G
• Catalyst Driver: 13.3 beta
• ASIC Quality (GPU-Z): 69%
• AMD Stream SDK: 2.8 I think, I need to re-verify
• OS: Win 7 64bit sp1
• Voltage Unlocked: seems like it

OC Settings:

• Core GPU: 1100
• Memory:950
• Voltage: 1200
• Boost: 20% or +20

Miner Info:

• Miner: Cgminer
• Config Options: -v 1 -w 256 -g 4 -k phatk -I 9 --temp-target 75 --auto-fan
• Hash Rates: around 660 average..
• GPU Temp: 62C

Special notes: I have 2 of these, but this one is clocked lower than my other which Ill post when I get a few min.. also usxing Trixx latest version to adjust the settings

[Cablez]

you can get the memclock lower than that if you use msi afterburner 2.3.0 with the two added ati files in the directory.  The final step is to never follow the reboot it asks for as that locks out the memclock control for some reason. See if that works for you, it should save dome more power and heat.

I don't think from what I have read that lowering the memory will get the hash rate higher, I think it just lowers power usage correct?  Currently not paying for power tho

Correct, it does not improve hashrate or hurt it. It solely brings overall card power down fairly well.

Very nice.. what drivers and sdk are you using?

What power supply do you have?

cheers!

Gateway: I'm kind of jealous of those temps. I can sustain 660 or so, but that's running 82-84C. Cannot figure out how to get memclock less than 150 MHz under core without causing very odd display problems.

[Bitweasil]

I'm running a DirectCU 7970 at 1200 core for around 710MH.  78C or so.

How can you get the core to go up so high. I thought catalyst control center limits it to 1125. At least his is with my CUII card.

[Kalen]

13.1 AMD Drivers, MSI-AB unlocks

CGMiner, Diablo, Intensity 10, other hash settings default

All Cards are at Stock Voltages

690-700Mh/s, 74C
XFX 7970 (FX-797A-TDFC Rev5, brown box)
OC: 1160mhz GPU Core, 1300mhz Memory
Default: 1000/1475

*Originally got 2. Despite identical stickers on the outer retail box, when opened inside one box was black, one box was brown.
*The brown box had stock bios v33, 925/1375.
*The black box had bios v32, 1000/1475.
*The black box one had awful fan noises at max speeds.
*When in crossfire mode, it seemed to me whichever card was on top overheated and had to be shut down. I have an Antec 300 case, with 2 front 120mm intake fans, 120mm side intake, and 120mm exhaust top and rear.
*Planning to return the noisy fan black box version for a refund.
*I did try swapping bios around between the two cards. No problems running on either. Kept the 1000/1475 bios for the brown box.
*Cooling is otherwise fine if the 7970 is on the bottom or by itself with open access to air.
*When I tested stacking the 5870 with 7970, and the 7970 is on top with no open space access, it seemed to cap out at 95C at default clock.

395-400 MH/s, 87C
XFX 5870
OC: 925mhz GPU Core, 300mhz Memory
Default: 850mhz GPU Core, 1200mhz Memory


I'd really like to get a second 7970, preferably with XFX. I'm not sure if the problem is with XFX Quality Control/Cooling Design, or you just need watercooling in 7970 crossfire setups.

[Bitweasil]

I push my cores on Linux with the atitweak scripts - no idea on the Windows side.

As far as cooling multiple 7970s, you can do it, but it's easiest if you put a space between all the cards.

http://blog.cryptohaze.com/2012/02/quad-gpu-builds-with-case-part-2.html is the general setup I use at this point, though I only put 3 cards in - 4 is harder to cool by a large margin and runs the cards much hotter.  It's just not worth the effort at this point.

It's much less dense than some of the builds I've seen here, but the data center doesn't like "weird" things in their racks - open air cases were not acceptable.  It's actually not that high a cost per system - if you can get the parts used, a $125 mainboard, $50 CPU, $50 of RAM, $100 PSU, and a $150 case will host 3 cards in sustained 24/7/365 operation with no trouble.

Nice setup.. what risers did you end up getting?  Hows the 1200 watt power supply holding up?

I don't use CCC to control my settings. I just use cgminer gpu settings.

Bought the risers off eBay http://stores.ebay.com.au/Micro-SATA-Cables based in the US but the risers have Flyconn on them and looks to be from China. I bought the 12 inch ones but the last time I checked eBay, they were out/no longer listed.

The AX1200i PSU seems to be holding up pretty well at 36c. They're only 2 months old. My Steplight power meter reads ~1400W atm.

What sort of uptime do you get? Win8, can't say I've tried that OS. I've tried on Win7 and Ubuntu12.10 and I can't get it to last more then 24hrs on 1200 clocks.

I just went on vacation for a week, and it ran at those clocks for 8 days straight with no problems. I've used this card in Win7x64 and Win8x64, same results. Try monitoring your VRM temps, and make sure those don't get too hot. I know some people say they're fine up to like 150C, but I try to keep mine under 100C.

[gateway]

I'm thinking of picking up some Gigabyte 7970 GHz Edition boards cause I think by default they are clocked at 1100, my sapphire ones are 1000 which I push to 1150 ish.. anyone have any thoughts about the Gigabyte card?
