Even if the new -advmethods Fermi units lower CPU PPD by 1k or so, it is well worth a 5-6k PPD gain on the GPU. wink.gif

Can you check the actual usage of the GPU client in task manager? That's what I'm looking for because I'd like to see how it compares to the 0-1% of the 762X

It looks pretty steady at 1%, with the occasional bump up to 2 or 3% while I was watching it.
It's average CPU use is higher than the average for my 9800GT, but the 9800GT lowers my CPU PPD by more because it has occasional bumps of 12-13% CPU use.

I've been running -smp 8 on my CPU because it was giving me higher PPD than the usually recommended -smp 6, even with two video cards folding. I may try switching to -smp 6 to see if that still holds true with the 470 crunching the new WU's.

I'm curious to see how they scale with more cores vs more clock speed, so I hope you get one soon. wink.gif

I picked up a 8033 on my 560 Ti HAWK and the tpf was about 10-15 seconds higher than the 8031's.

Oh one more thing have you noticed these WUs running hotter or cooler than the 762X or about the same?

For me they seem to run a few degrees cooler, about 2-3 degrees Celsius

These new 8031 unit is great. I was getting a very consistent 20,557 PPD on the old 762X unites and I'm getting 27,673 PPD on the two 8031 units that I've had.

 

TPF on the 762X was 3:38 to 3:39 and TPF on the 8031 is 2:00 consistently.

 

Interestingly enough, the  8031 unit runs 1C cooler than the 762X do. I'm at 100% GPU fan and still sitting at 77C on my GTX 580. (The 580 is at 928 core / 1856 shader / 2106 memory / 1.150V and I haven't had any errors with the new units.)

 

(EDIT: I had to wait for temperatures to stabilize after returning my system to the same conditions at which I tested temperatures and power in my folding efficiency thread to get an accurate comparison.)

 

 

CPU usage with the 8031 unit has been  0% for as long as I've watched it; it seems to use less CPU than the 762X units did, as they would bump up to 1% CPU use occasionally and this client has not done so at all.

 

 

EDIT:

 

This WU seems to like having the SMP client running with it, as my TFP was 2:02 without SMP on all cores and 2:00 with SMP on all cores; this is the same behavior that the 762X WUs exhibit.

 

This unit seems to use 1% less electrical power (in my system) than the 762X units do, and as it performs almost 35% better in terms of PPD, this results in a significant PPD/W efficiency gain with this WU. However, the CPU SMP client alone is still more efficient in terms of PPD/W and in total power consumption.

 

 

These 8031 (I haven't had an 8032 or 8033 yet) are a good step in the right direction for Fermi point values for Stanford, but they're still not anywhere near a big enough step to normalize PPD to power consumption when compared to SMP clients. I'm still hoping for a QRB system for Fermi clients.

You're welcome. If you need any more information, let me know.

 

I updated the power consumption thread with 1.138V data, but what I posted above was 1.150V data. Power consumption at 1.138 V on the GPU was 10W less than power consumption on the 1.150V GPU setting. I use the 1.138V for 24/7 folding dedicated folding, but I bump up to 1.150V if I'm multi-tasking / gaming while folding to eliminate the rare NAN that cropped up once a month or so at 1.138V while gaming.
