Title: Post your 7970 Card info and Settings Post by: gateway on April 18, 2013, 11:04:59 PM 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.

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. Title: Re: Post your 7970 Card info and Settings Post by: gateway on April 18, 2013, 11:19:40 PM Ill go first:

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 :) Title: Re: Post your 7970 Card info and Settings Post by: Cablez on April 19, 2013, 06:37:39 PM 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.

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.
Title: Re: Post your 7970 Card info and Settings Post by: Bitweasil on April 20, 2013, 05:15:29 AM I'm running a DirectCU 7970 at 1200 core for around 710MH. 78C or so.

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. Title: Re: Post your 7970 Card info and Settings Post by: Bitweasil on April 20, 2013, 02:43:00 PM 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.

I just use cgminer gpu settings.Nice setup.. what risers did you end up getting? Hows the 1200 watt power supply holding up? 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. QG Title: Re: Post your 7970 Card info and Settings Post by: crazyates on April 21, 2013, 06:10:54 PM Card, Drivers, OS etc:

Ya that's the one I have, the Gigabyte with the stock clocks at 1100MHz. Mine clocks up to 1200MHz no problem. Core stays nice and cool, but the VRM temps are a lil high for my liking (while mining, gaming is just fine). It runs a lil higher volts than stock to accommodate the higher stock clocks, which also helps with the OC as well, but also explains the VRM temps. It's sort of a trade-off, but I think it's worth it. Title: Re: Post your 7970 Card info and Settings Post by: Spendulus on April 24, 2013, 09:34:37 PM I'm running Giga 7970, totally stock, 550 and 600 Mh, had heat issues that kept me from dreaming about upping the parms. They are now fixed, so I'll be optimizing but here is a question.
Anyone doing water cooling and if so what rig/part numbers? Title: Re: Post your 7970 Card info and Settings Post by: nookiegirl on May 15, 2013, 08:41:11 AM I am also thinking about getting the Gigabyte Radeon HD 7970 OC (GV-R797OC-3GD).
As far as I have read here in the forums, it seems to be the best choice for BTC mining. Any downvotes on that?
