New GPU3 Projects

Well its kind of nice to see something a bit interesting come out on the GPU side.. all this talk about bigadv over the last year has taken the focus off gpu to some extent. sounds like these WU's are putting a serious hurting on GPU's.. I wonder if there will be any issues with the throttling methods put into place to limit draw when using stuff like Furmark. were those all implemented in software or is there a risk that people will run into hardware throttling?

On the Nvidia side I believe they are still being done on a software level in drivers. I imagine EVGA would have a lot of pull with Nvidia as to whether or not it gets added, obviously they want as many points as possible but if they start seeing higher RMA rates from noobs folding at 105C nonstop they may have to change their stance.
 
Just went from the 275 drivers to the 280.33 WHQL.

My early experience is saving 2-3 seconds per frame.

My 570s are at 4:24 with a savings of 2 seconds
My 460 is at 8:22 with savings of 2 seconds again.

Not sure about the effect on the bigadv WU. It will be an hour and a half before I have those numbers. Additionally I found some freaking microsoft audio graphing process using 2.5% of my processing power, across 12 threads, that is a huge hit. I couldn't kill it, but it suspended just fine. Wish I remembered the name of it, started with an "a", I'll probably have to suspended it each time I restart the rig. I don't need sound on a daily basis, but when I finally get my xbox360 (normally attached to that computer) replaced, I will be needing sound once in a while.
 
Well the bigadv is now a 2686... usually not quite as many PPD as a 6900.

Down to 24:40 a frame, these are some phenomenal improvements for me. All without having to shutdown the 40KPPD of GPU folding.

are you still running smp 10?
 
smp 12..... I found that engaging all 12 threads got more PPD, before these new GUP3 WUs trying GPUs combined with my 970 got me 30 minute frames.

So now I'm GPU folding and seeing benefit from my last two threads. Maybe not as much as running without GPU at all, but at least 12 is faster than 10, probably should be the same for a 8 core CPU.
 
anyone not been getting these units. i seem to not be able to pull anymore
 
I'm half way through two WU's. Four hours till the next batch. Maybe they're running low?
 
Running low? I've got 12 of them crunching now. Latest one just downloaded and started 15 minutes ago.

Filter, you've got GPU3 client paramenters set for -advmethods, right?

Good to hear! I'm liking these WU's.

Also... 12 450GTS's?? You are a god among men.
 
God among men? (watch out, a lightning bolt just missed me) I used to run dual 9800GX2s and then upgraded to dual GTX 295s. The heat and electric bill became too much. I 'upgraded' to GTS 450s during an upgrade cycle due to the 450s' lower power draw and quieter operation. And, at the time, the GPU3 work units in circulation had close to the same productivity on 450s as they did on much higher powered and higher priced video cards.

OK, I'll move us back to topic now. The newer generation (I think it's more than a brief experiment), 762X work units, favor the more powerful Fermi cards. But the tradeoff is that the new GPU3 Core revision, 2.20, enables much more efficient system operation. I have been able to shift my CPUs in bigadv SMP Folding from seven threads (-SMP 7) to -SMP8, resulting in much better bigadv production. What I lost in GPU3 production I have picked up with SMP.

So it's a mixed reception from me.

Sort of the same for me.....

460.......-2000PPD
570s..... same PPD
970.......+4000PPD

so I profit, but only marginally

or do I.... 2000PPD for 200W of power is hardly an improvement
 
:D:D:D

All our contributions end up in the same pot.

not to worry, no offence taken at all

I like the smell of burnt GPUs in the morning. Not from our team of course. ;)

Bwahahaha!!!

My 460 is OC'ed to 849Mhz core and the temps went from 58-61 for the older WU to 69-72 for the new WU. Fan speed went from a very quiet 1500-1600 RPM to a noticeable 2100-2500 RPM (I have custom fan curve in Afterburner). I'm still putting out 11580.3PPD with it so PPD hasn't changed for me on these new work units.

Edit: And my power draw at the wall went from 262 watts to 284 watts.
 
jfb9301 said:
just did some math as I started to ponder what my power supply was feeling.......

1140W from the wall.....
1200W Power supply......
Power supply at 95% full load....

I don't think it is as easy as that...

It's probably safe to assume an efficiency of ~85%
0.85x1140=969W
969W/1200W=80% full load

but for conservation's sake it's safer to assume your power supply is 100% efficient rather than guess.


I really hope BFG power supplies are solid, as I cannot afford to go shopping for an AX1200 right now.

The H has a great article about the black art of dual PSU's on the front page so you can ease the load on that sweaty BFG :D

I have to also report these units are degrading desktop performance and running hot.

Also I noticed, (never saw before, think it's a new issue) that the GPU usage drops to nearly 0 and then spikes when clicking a link and rendering a page on firefox. I assume this is the hardware acceleration causing the F@H CUDA prioritization to drop to low.

I have SLI'd cards, and this only happens on GPU2 according to EVGA Precision.

Yes, desktop performance is somewhat degraded with pauses and hitches. Seems to be less of an issue if you have enough free system RAM available, but gets noticeably worse as free system RAM gets low. Netflix streams get a bit jerky too.
 
i wouldnt put faith into that, its the end of the month and its only a few days till the bucks turbo boost kick in again.

You are forgetting about the new work units that are causing 10C spikes on Fermi hardware :rolleyes:

I perused their forums and a few are talking about having to downclock to stock clocks and monitoring their GPU temps. Of course some are switching off -advmethods flag to get the other WU's.

I don't know about that. I have 16GB of physical ram on my main desktop. Gemerally 4.5GB is in use at any given time. Sometimes it is almost all in use when games are running. But I was getting real jerkyness with just IE 9 open while still maintaining 11 free GB of ram space. I just turned the -advmethods flag off, it obviously needs some tweeking.
