I have 13 diamond 5970's from newegg

linuxcoin final
cgminer 2.0.7
engine 800 mem 300 stock voltage 1.05
700 mh/s
stock cooler with replaced TIM(shin-etsu) and phobya thermal pads

2 on water with EK blocks in windows
830/300 stock voltage
750 mh/s
cgminer 2.3.2

8 5870's from ben's outlet

6 on air with linuxcoin as above
900/300 1.125v
400 mh/s

2 on water
900/300 - so far they won't go higher even though their temps are like 35c these cards are solid, but won't go past 900 and won't undervolt either
400 mh/s

I agree, that would be ideal. Unfortunately, I doubt there is any consensus on what a "typically obtainable" core overclock is, and I do not personally know enough to determine one, so I decided to leave it to the judgement of the submitter. If there is a resource I could use to obtain "reasonable overclocks", though, please share it; I would be glad to change the guidelines as such.

Perhaps a mean with a variance would be more helpful here.

Updated. Those are some impressive numbers.

A mean of what data set? The wiki?

Whatever you decide is a useful and valid data source. I would take just the submissions in this thread. That way you can ask questions to the submitters about the some settings that you cannot do via Wiki.

Hmm. I'm not sure I have enough data here for anything meaningful. If I see a result off from the norm, though, I'll definitely query more closely.

Updated. Kept the other 6950 due to it having locked shaders.

That would be expected! I should have posted with the same clocks to compare locked/unlocked more accurately. With the multitude of 6950 models, this list needs a 1GB version too.

There was one posted by bitlane on the first page, but it had the same MH/s as his non-1GB model, so I didn't think it worth adding. Memory size is effectively irrelevant to hashing power, so unless it affects necessary settings, I don't think it would be necessary to differentiate, but I've never had personal experience, so enlighten me if there are any significant differences with regard to mining.

For now 1.024V 850Mhz Core runs all good.
5850 MSI two cards, each arround 330Mh/s

Sapphire radeon 7970 on air, cgminer 2.4.1, default cgminer settings (which work out to -v 1 -w 64 -k poclbm) Cool:

GPU 0:  74.0C 3027RPM | 734.9/735.6Mh/s | A:445 R:3 HW:0 U: 10.51/m I:11

73.0 C  F: 52% (2929 RPM)  E: 1230 MHz  M: 1080 Mhz  V: 1.170V  A: 99% P: 5%

Ambient temp ~17 C. AMD driver 8.921 AMD OpenCL SDK 2.6 on debian linux stable 64 bit.

(note fan speed looks slightly different because GPU status line taken a few seconds later).

Primary developer/maintainer for cgminer and ckpool/ckproxy.

Huh, something doesnt quite add up, a 5850 at 850 doing 400Mh , either you run imaginary superman juice on that card or something doesnt add up, seems way to high for that clockspeed.

Your right, that was only a peak. ^^
Under Desktop usage the cards have ~330Mh/s

That's very strange - running non graphically-demanding programs should not take 70 MH/s off...

One Day i open the Monitor and the last thing i see for a few second was 800Mh/s on the Guiminer. Then it fall back to ~660.

You should find these results interesting I think.

You get the same results without updating Phoenix and even with guiminer v2011-07-01. The key is running a second worker.
Those are fake reports of guiminer I guess. Best to check your real hashrate is to use 24h stats on ozcoin. And could be as well that you're getting extra mhashes out of your cpu. Check your cpu usage.
