New F@H cruncher box

[brownstone]

What video card ? I have 10 different nvidia types of cards, running different driver versions. NONE use any cpu. Oldest drivers are 182 something.

You answered my question. None use any cpu. For some reason my gtx460 started out in the 8-9k range and then dropped to the 3-4k range for about two days. As soon as I turned off the classic cpu folding the gpu ppd jumped back up to 8-9k. Not sure what was going on.

 

[JeffCos]

I don't suppose that with a hexcore that you lose any ppd by running both clients? I ended up shutting down my dual core and just folding with my gpu on my machine because it seemed to be messing with my overall ppd by running them both.

Happens to me too. Core i7 OC'd to 3.612 15kppd with just the cpu, 8k with CPU and GPU. I'm probably doing something wrong.

Now if it could only get a bidadv. When I downloaded the smp2 client, it no longer uses that "install.bat" or even installs anything. Whats with that ? or did I install the wrong client ?

The new client no longer uses MPICH, that's why no "install.bat".

Edit: It also looks like there may be a shortage of bigadv right now, I just got a regular SMP & judging by GLeeM's latest points he did as well.

Have you set the GPU priority slightly higher than default (low instead of idle)? (And the CPU should be left at the lower setting)

 

[theAnimal]

But its only doing 9300 ppd with 8 real cores ! My 1090t is getting 12k right now, and my 920 is doing 5700. WTF ? The nehalems are dying on the current units ??

You remembered to add the passkey? HT is on and both CPUs @ 100%?

I have set the gpu priority higher and made sure that they are running different machine ID's. Fortunately, I'm still folding about the same ppd with gpu only that I was with both gpu and cpu going. That classic client doesn't offer much.

I did not do that, I'll have to do it when i get home tonight. I remember reading something else on here about the affinity lock. Should it be enabled or disabled while folding with CPU and GPU. My GPU is an ATI 5770, I know the Nvidia's fold better, but can't do anything about that now. I looked at CPU usage with both clients on and it had 83% for the CPU WU and 13% for the GPU WU. Thought it sounded really high for the GPU.

 

[VirtualLarry]

aTI uses more CPU cycles for GPU than Nvidia does, at least as long as you are using a 180.x or newer Nvidia driver.

OK, its been a long few days... Here is the latest. The motherboard has one bad dimm slot, the very first one you are supposed to use. Took me until an hour ago to figure that out.

Then I experimented, and found that by using the 3 slots on cpu2, its now working in triple channel mode, and sees the whole 6 gig.

Then HFM was braindead, but the latest is that I really do have a 2684 and its taking 50:48 per frame for 16717 ppd.

So, the question is, what PPD should a 920@ 4.2 ghz get with HT on ? If I am getting that, then I am not returning the motherboard. I think that 8 cores @ 2.3 should be close to what 4 cores @ 4 to 4.2 get.

And this is winXP 32 bit. I don't get as much ppd as you guys on my 920 with the same OS. only 5-10k.
And have you played with HT on or off ? I have mixed feelings on that. I wish I knew for sure which is better for F@H.

I'm running a core i7 920 @ 3.6 win 7 64 bit, HT on and depending on the WU i max out around 15.5k ppd. So I'd think you should be getting considerably more with yours at 4.0-4.2

From HFM.NET Benchmarks:

Project 2684
Number of Frames Observed: 300
Avg. Time / Frame : 00:46:57 - 19,144.0 PPD

Project 2686
Number of Frames Observed: 199
Avg. Time / Frame : 00:34:45 - 30,064.5 PPD

i7 920 at 3.99

Gleem, what OS were those benchmarks run on ? win 7 ? If so, my 17k is in the ballpark with XP.

Thanks !

JeffCos, mine run at 2.3, but I have 2 in the same box. Trying to see if I am in the ballpark (2 x 2.3 = 4.6, but not linear, so 4-4.2 was a guess)

One bonus here... I am getting the same or better ppd as my 920 was, but I had all sorts of stability problems on bigadv units (even though regular units NEVER EUE'ed), but now I have server hardware and not overclocked ! 44k ppd in one box ! 125k ppd total

Here is the current farm(I have half of it turned off, not cold enough yet)

I haven't since bigadv requires 8 cores.

 

[Mr. Pedantic]

HT on is better.

Are you sure your E5520s are running properly? They should be getting better than 16k, even on a 2684...

Well, by my 920's stats on XP, the best I can tell, they are on track for the right numbers. If you can tell me where I am wrong, please let me know.

That's a 920 at 4GHz, you should be getting nearly 25k at perfect scaling. How's your memory set up? Is it still 2+2 x2GB, or 3+1 x2GB?

 

[Markfw]

its 3x2 2g and its windows XP. I think thats the factor. My 920@3.9 (the best I had) could never hit anything over 16, and lately, over 10.

 

[Mr. Pedantic]

Wow. So you can run bigadv on 32-bit? Because you shouldn't...bigadv really needs 4-5GB of memory to work properly. And having proper triple channel helps as well; try adding another DIMM on so that both CPUs have 3 DIMMs in their slots; from what I know bigadv is really bandwidth-sensitive.

OK, so I have 2 video clients and a bigadv unit running, and its taking 2 gig ram total. So why is it I shouldn't do this ! ( 3.5 gig minimum available)

 

[Mr. Pedantic]

Oh, wait. Sorry. That was for the old bigadv client. My bad. You should, however, still add another DIMM if you can scrounge one up.

I have 3 x 2 gig for 6 total, but XP can only see 3.5. Why would I want 8 ? And, I have 3 on one cpu and none on the other as its got a defective slot. I can't return the motherboard, I can only order another one, but it would be new, not open box, and be $100 more. I only spent $200 on this one !
