These haven't been running for a while so I don't really have any PPD numbers but they should match up with others of the same spec. There's a google doc floating around that has PPD numbers in it for various configs and project types.
Things have changed recently and I no longer have the space for keeping my farm running so, pretty much everything must go:
4 x 6180SE: $750
4 x 6172: $450
4 x 6166HE: $500 (oc'd to 2.2ghz w/o issue)
2 x SuperMicro H8QGI+-F: $450/ea
1 x SuperMicro H8QGI+-F: $450 - this board has the [H] bios...
I finally found some time today to get one of my 4P's back in the loop. Still have a few other boxes to check - may have the full farm running again by days end.
Is it possible to get bigadv units on Windows with the new v7 client? I had to switch over one of my Linux boxes to Windows and I've added the follow flags: client-type bigadv and max-packet-size big and still only see regular smp units. Is there a flag I'm missing?
I have two new in box EVGA GeForce GTX 560 Ti 448 Cores Classified Ultra cards to sell. These are factory OC'd see here for details.
Everyone Price: SOLD
[H] Folders Price: SOLD
I'm seeing quite a few of these 8301's now - processing 4 of them currently.
I like these things - just got one on one of my 4P's and qd reports: 530247.56 ppd
If things are crashing at stock speeds/voltages than I'd suggest testing out the ram with memtest would be a good place to start. If that checks out as others have said it's probably an issue with the psu or mobo.
I've had good luck w/ spicy chips and the Supermicro X9DAi. Having said that you should really double check that post code to rule out anything else being the issue.
So, has anyone gotten a hold of any 6300 series chips yet? Kinda tempted to look at upgrading my 2x6272 box but it has to be a pretty nice improvement to be worth it.
I still think you should look at getting new (and bigger psu). Per nvidia specs 450W is the min. psu size for the 460 and your OC is only going to increase that power draw
If you are OC'ing it - you might want to look at pulling the OC back a bit on the next card. Also with that many cards dying in the same system I'd really think about replacing the PSU as well.
Let's see:
4 x 6166HE @ 2.2ghz
4 x 6172
4 x 6180SE
2 x 6272
2 x E5-2660
2 x E5-2660
2 x E5-2620
2 x E5-2643
3 x 560Ti 448 core
Plus a few other random boxes that don't add much to my ppd.
Yeah going caseless is really the way to go especially with multi gpu setups. Lots of heat to dissipate and the more airflow you can get them the better. I've actually been pretty surprised by the temps - as these cards are factory OC'd: 85 C, 83 C and 70 C. Also I highly recommend the...
FahCore15 is only supposed to be for Fermi or newer if I recall correctly. Sounds like Stanford servers giving out incorrect WU/Cores to the wrong hardware. Try removing the work folder and the cores and start the client again. See if it picks up a WU/core combo it can actually process.
The AMD GPU's themselves aren't bad it's the folding core they use that's the problem. Also, I believe the Nvidia folding core is still reliant on CUDA - which means it wouldn't be possible to use them in a setup like this for folding.
Just brought online two 560Ti 448-core cards. Will probably add a 3rd at somepoint, but want to see how it runs with two. Also want to see what the power usage is like.
