I just ran an SMP unit for folding. Both to confirm stability and also to give you guys more data points.
At 20% it was running 12:30 frames, at 50% and above it started running 12:45 frames. Memory slowing me down I guess.
So far I'm 12 hours prime stable, over 24 hours of SETI with no validation errors and 1 SMP unit returned ok. Not bad as a stability test I guess.
SETI is a GREAT stability test! Nowadays I run Orthos for about an hour then put the rig on SETI. After you've crunched 2-3 days than check for compute errors - you'll have enough results by then (IMO) to confirm stability.
SETI CPU times as follows:
CPU / speed @ RAMspeed ................................ 50-52 Cr; ~54 Cr; 73-75 Cr (credits)
FX-55 (90nm) 2.9 GHz @ 223 MHz CAS 2.5: 76-7800; 82-8400; 88-9000
Opty 165 2.9 GHz @ 263 MHz CAS 3: ................. 78-7900; 85-8600; 90-9200
5000 BE 3.2 GHz @ 400 MHz CAS 4: ................... 80-8300; 85-8800; 93-9500
4400 X2 2.6 GHz @ 238 MHz CAS 3: ................... 85-8600; 90-9300; 9700 (only found one)
Your Phenom (for easy comparison):
Phenom 2.6 GHz @ 315 MHz CAS 5: ................. --------; 82-8300; 8800 (72 credit)
You're getting about the same times as my best cruncher but you're running 10% slower on the CPU!
I'd say that's a MAJOR step up!!!
Now if AMD can get those Phenoms running just a
little faster I'd say we have a winner!
But even now it might be cheaper to build a Phenom system than a pair of Opty 165s - I'll have to do some cypherin'.
@QuietIce- the difference in SETI times may be due to the lack of L2 on your AM2 vs. your 939 Opterons. We see this on the Folding side of the fence as well. The larger L2 really makes a big difference.
I have a 170 @ 2.7GHz & a 5000 BE @ 3.1GHz both Folding in Linux and the 5000 BE just barely out paces the 170.
I hadn't thought of that -
DUH! Now that I think of it ALL my s939 rigs are 2x1Mb L2, even the X2's I have.
If anything the L3 on the Phenom should HELP, if true (and from the above results it might be!).
Guess I'll have to get a rig built with this (s939) 4200 I have sitting around so I can compare - it's the only 512K chip I've bought ...
