Low PPD dual Xeon x5570 [No]

[clockwise]

Hi everyone,

New to the forums, and somewhat new to folding. I picked up a couple of Dell 610 servers and decided to put them to work. The test box is a dual CPU, 16 thread machine running 2008 r2 and fah 7.3.6. HFM is saying its capable of ~25k PPD running core 0xa4 with a TPF of 11:36 . This seems low, anyone else out there running these CPUs?

If you want to do well with 32 threads you need to run Linux and configure it to get bigadv's. Windows, which can't run them, and thereby can't compete PPD-wise.

Welcome to the folding@home support forum clockwise.

Your HFM estimate appears to be correct for your setup. I don't have that exact model CPU but do have a system with dual xeon 4c/8t CPUs for a total of 8c/16t and do get in the 20-25K PPD range. While it's true that running in Linux might get you slightly more points you would not be able to process the bigadv work units before their deadlines with your particular model and would actually end up receiving much less PPD.

Make sure you have a passkey if you want to receive the estimated points. Otherwise you will only receive the basic credit which is much lower.

Welcome to the forum

25k sounds right, my dual hex core L5640's will get 53k PPD, that's with the extra cores and the benefit on Linux. You can't run bigadv units with those cpu's, Dual intel quads need to be clocked to about 3.6ghz to make the deadlines.

SMP CPU folding is now way down the list of ways to get good points. I still have a 4.6GHz 2600K folding but am considering turning it off as its 20K per day is less than I can get from a 560Ti. The points value at the moment is in high-end SMP - 32-thread boxes - or high-end GPU like 290X or GTX780Ti.

Thanks for the info.

Time to switch gears and invest in a couple GPU's then. At full load this setup is pulling .48kw, for a measly 52PPD/watt

From my very raw calculations, the 7970/7970 ghz look to be the best bang PPD/watt and PPD/$$.
