Impressive work, very nice. If you don't mind me asking, are you an electrical engineer by trade?

Deanzo said:Thanks mate
Very helpful
MadMan007 said:Wrong terminology maybe, by 'clock domain' I meant the different core/shader/memory clocks. He was specifically talking about the memory though so your specific clarification was nice. So Rivatuner's graph shows the true clocks?
Deanzo said:Thanks again mate,
This is a must know imo for working out the best set up of the card.
On stock cooling / bios volts anything over 729 on the core is a no go, but then again it may well be the shader clocks holding me back.
Not that Im unhappy with 729/1215
And thanks for the tip using ATItools with Rivatuner, that will save me some time
ViperJohn said:Will the card hold that 729 core clock hold in a 3DM01 Nature Only torture test (25 repeat passes
(not loop!) with the title screens disabled) and not core lock???
I would be very surprised if that 1215 memory is truly clean in ATItool SoA.

ViperJohn said:If you run ATItools Scan for Artifacts you can bring up RivaTuner then use it to change the cores 3D ROP clock in 9Mhz increments (Even, 1/3 and 2/3's multiples of 27) and then see the true core ROP and Shader clocks immediately in the graph. For the 8800GTX cards do the same with the memory as the GTX's will step the true memory clock at some 1/3 and 2/3's multiples. Just write down what set clock produces what true core ROP and Shader clocks (and the memory on the GTX cards) and you can save yourself massive amounts of OC trial and error time!
Deanzo said:Im not sure about either at this point, but I can tell you it will run at that speed for all benches,
Im along way off saying for sure its 100% clean.
But I will do as above and post up my results.
I for one hope it does pass, but then I would
ViperJohn said:Well i'll be dipped in sheep stuff. You guys with Ultra's check for memory stepping on the 1/3 and 2/3's multiples of 27.
I have two identical eVGA 8800 Ultra's here right now that are only five cards apart in serial numbers. They both have the same bios (hell there is only one for an Ultra ATM). One card will step the memory at 1151 (27 x 42 2/3) and several other 1/3 and 2/3 multiples while the other card will only step the memory on even multiples of 27come hell or high water.
It's definitely got me scratching my head lol.

Is this good or bad news for my card? How is she doing in your little boot camp session?
Deanzo said:Hey VJ
Im giving this a wee bump as I was getting a little OT on nicasoft thread and as this all got started here, best I just keep it to one thread.
The below is on a 40 repeat pass (not loop) with the title screens disabled, 3DM01 nature only torture test.
Core 720, Shader 1782, Memory 1080 (stock), Max temp 67c
Something you said in the other thread got me thinking, when I tried this last time I was running the memory at 1215 and thats why it may have locked up on the 3rd pass.
So for now I'll leave that alone and just see what the ROP/Shader will do, Im about to try 729 true, then 756, I hate how its such a big jump there.

PhysX said:why do ppl still test with 3dm01 ? its not accurate, ive seen over 125k...
Deanzo said:Im using nature as a torture test,
And the best score so far with 01 is 104905 done with two Ultra's in sli 1008/1224 cpu 5310 all under ln2
