New larger WU (4742-4747 1254 atoms)

[Right]

Just recieved new WU 4743. Noticed that this WU are less CPU limited! Bravo!
For examle on old WUs wit 544 atoms my HD 3870@850MHz was loaded approx 70-75% with AMD Opteron 165@2,5GHz.
With new WUs, Opteron 165@1,7GHz enough to load same HD 3870 at 99,99%!

What is your PPD?!

[Right]

Around 2400ppd.

Good news, (especially for those of us with CPU-challenged boxs)! I wonder what I'll find when I get home tonight...

4870 @ 825/1000 fed by a SLACR Q6600 @ 2.31GHz*

XP32 SP3, Catalyst 8.7

GPU set to Low priority over a SMP core set at Idle, no core affinity set

21% out of four CPU core cycles used (84% out of one), unchanged or unnoticeable, GPU pegged at 99% (was 80% when running 544 atoms WUs)

Fan forced @ 35% minimum, 78C GPU temp (was 69C when running 544 atoms WUs)

Looking forward to 2000+ atom CPUs, hell, go straight for the 4000 mark !

*I'm forced to underclock the CPU due a limitation of the Asrock 4CoreDual motherboard, switching to a P5Q Deluxe this weekend so I can OC this puppy.

Good news, (especially for those of us with CPU-challenged boxs)! I wonder what I'll find when I get home tonight...

My ancient 2.33 GHz Athlon XP+ with a stock Sapphire HD 3850 AGP 8x card likes P4742! On the P4727, I was seeing one percent of the WU complete every 2m32s; with P4747, it's 4m06s. The CPU is still pegged at 100%, but it looks like more Kernel time (maybe double) and less user time. End result: P4742 WU is estimated at 6h50m completion time vs. 4h14m05s for P4727, an increase of 61.4%. InCrease shows the pph at 79.997, or over 1,900 ppd!
(I looked at the GPU utilization: 99% on P4742 vs. 58-62% on P4727. Hurrah!)

Not bad for a box that I salvaged from the scrap heap...
(edit: my old eyes got it wrong: it was actually P4742, not P4747. I've changed my post above.)

It looks like there is going to be life in those AGP cards for quite a while longer.

[Foxbat]

Since I was at 99% GPU utilization, I tried overclocking the GPU and Memory on the HD 3850. It brought the GPU temperature up to 81˚C and the time per percent (per frame?) down to 3m50s. The would raise the potential ppd to just under 2,200. I don't know if the 80+˚C temperatures are "good" for the GPU, though, vs. the 70˚C I see with the smaller Projects.

[Viper666]

So the ATI client now runs with no SSe2 processors? and 2000PPD on Agp boards?

[Trivolve]

How much GPU Utilization does this have?

Hmm!!! Knew that mhouston was going to work out issues limiting old Athlon XP+ CPUs while driving GPU2 and had somehow missed any posts stating that he'd already fixed it. (Or were XP+ issues confined to nVidia chipsets?)
Thanks for your post!
By the way, that's a nice OC you have on that old XP+. Good job.

[mhouston]

Sorry, I forgot to dig up the old thread about SSE2 being needed to say that we fixed this now. Hopefully this can breath new life into older AGP machines. Do note that for smaller proteins the older CPUs will be CPU limited, but you can probably get much higher PPD running the GPU2 ATI client in those machines than a uniprocessor client.

[Viper666]

your the man mr Houston !My friend still uses my old 3200+ to play wow, i think he needs a new video card LMAO

[Foxbat]

How much GPU Utilization does this have?

On the new P4742 & P4745 (Run 1, Clone 39, Gen 4) the HD 3850 is seeing 99% GPU utilization and 79˚C temperature (according to the CCC Advanced control Panel. I've run the Clock up to 720 MHz and the memory clock at 950 MHz.

@alancabler, the Athlon XP 3200+ came from HP running at 2.33 GHz; no OC there. According to Wikipedia, it was only available in the HP d325.

@mhouston, you're definitely right about the GPU2 being better than the Windows client. I stopped Folding on the HP d325 because the 100-200 ppd that it produced wasn't worth the heat and noise that it also produced. While the new rig generates more heat, it is 10-20x the points, too.
