Looking For Advice On Tweaking 7970

[pccs]

Finally got up and running with my XFX DD 7970, turned out all I needed was the 6 pin to 8 pin PCIe adapter. Just wouldn't work with 2 6 pin PCIe.

Now that I got that problem out of the way, I'm looking for some advice on CGMiner tweaks and other things I can do to maximize coin generation.

Sys Info:
Xbuntu 12.04
CGMiner 2.11.4
AMD-APP 2.7
Catalyst 13.1

GPUs
1 XFX DD 7970 --- Plan on getting another one soon, maybe not XFX tho
1 Diamond HD6450

As far as I know the XFX cards are locked so there are some things I can't change. The only thing I have done so far is change the Intensity. The XFX card runs about 72C all the time, doesn't matter if the intensity is 1 or 10, that seems kinda odd. Edit:(The temp does change when I change the intensity). After I post this I'm gonna shut down and turn my fans on 100% and see what that does for the temps. Running in closed case with 4 fans, I cut two holes in the side of case and have 2 fans blowing directly on the Graphics cards.

Edit: Tried cranking up the 2 side fans to 100% and the XFX temp stabilized about 67C. Pretty small gain for a lot of extra noise.

Currently I'm getting about 590-600 Mh/s using just the 7970. The sample output below is using both cards.

Getting a little hotter now ... up to 76C and CPU temp goin up lol.

The best I can get out of the xfx 7970 dd is 630mh @ 1050/900 intensity 8, 73c during day 68-70c at night. Had accidently ran the card to 120c before crashing.

Dont need heater at nights now with 7970 and 7870 hashing away

I am considering changing to arctic cooling to make it cooler

[pccs]

I think I was running right around 600Mh/s on BTC, without any mem or clock adjustments.

I'm trying LTC now and can get max 520Kh/s with upping the clock and mem to max settings, runs stable there with no HW errors. LTC temps are 69C, with one card in the box(and 4 fans...not maxed out tho). It's actually pretty quiet. There is a certain speed that the XFX fans make more noise, hope that doesn't get any worse.

I've got (5) 7970's running at 690Mh/s each.  Stock voltage with 1150/475 settings. Intensity is set at 13.

I've got 2 on one mobo, and 3 on another.  They are all in an open chassis setup with good forced air ventilation, and the hottest card never goes over 80C.

Whoa, 690 Mh/s each? My MSI r7970s are pumping out only 590 Mh/s each... Can you spill more detail plz?

Which OS, which miner app, which card, & which drivers? Are they really not overclocked at all?

Thanks in advance!

Which vendor .... XFX?

BTC: I can get to 635Mh/s, with engine clock @ 1100, when I try to lower the Mem clock the card crashes.
LTC: 645Kh/s with Mem at 1700 and engine at 1075

OS:  Ubuntu 12.10 32-bit
Miner:  cgminer 2.11.4
Card:  Gigabyte 7970
Driver:  SDK-v2.8


I played around with my core/memory settings a little more this evening and increased my hash rate by just a little, and it seems stabler now.

Core:  1150
Memory:  800

Intensity: 13  (one card is set to 10 due to HW errors)

[pccs]

Tomorrow I think I'll try the 12.8 drivers. I'm using the 13.1. Maybe I can get a little bit more:)

Another thing that doesn't work is when I put the engine and mem clock settings in the script it crashes. I have to start cgminer with the default settings then go in and tweak the engine/mem. Anyone else have this problem?

Here's what I'm using in my start-up scripts:

BTC Start up: cgminer -o http://stratum.btcguild.com:3333 -u ... -p ... --device 1 --intensity 9 --auto-fan --temp-target 65 --temp-overheat 75 --temp-cutoff 80

LTC Start up: cgminer --scrypt -o http://pool.give-me-ltc.com:8080 -u... -p ... --device 1 --intensity 13 --auto-fan --temp-target 65 --temp-overheat 75 --temp-cutoff 80

Stock volts, which actually is different per card based on ASIC quality. #1 is 1.175, #2 is 1.1125, #3 is 1.05 at 70, 81, and 85 percent asic quality, respectively. Win7 x64, 13.3 Beta driver, diablo kernel, 128 worksize, default vectors (1), 2 gpu threads. Oh, all three cards are reference as well.

It means they are reference. Google it.

It means brand doesn't matter
