Folding@Home on Core i7: Bonus points for 8 core Linux VMs

Drenlin said:
Has anyone tried this with anything besides an i7? Like a multi-CPU Xeon/Opteron rig or something?

If you check out this sub-forum of the Folding@home support forum, there's some more info from people running workstations/servers:

I'm generally surprised how decently well the i7s rate against older 8 core (non-hyperthreaded) machines--of course, the i7s get creamed compared to 16+ core machines.

Possibly a bad memory module? Put them in one at a time and run memtest on them(if you havent already).

Thanks, I've tried that. I've tried testing each DIMM slot with one stick of RAM as well, so I think I've ruled out a bad DIMM slot on the mobo. Any other suggestions are welcome though. I've pretty much ran out of ideas.

Contact your motherboard support?

Maybe I'll give them a call. It's some type of hardware issue. I'd prefer not to RMA the board as I don't have another x58 lying around.

Exactly, but if the board needs RMAing you might as well do it before the warranty goes! Also, it could be some quirk they know about that would be a simple fix.

That's right. I'll give them a call today. Hopefully they have good US support. I've never called Foxconn.
 
So, I called foxconn and the dude told me to check the pins on the socket. If any are bent, that may cause this issue since the memory controller is now on the CPU. Some guy at hard forum had the same problem and apparently this was the fix. I'll give it a shot and report back.
 
Dang, I forgot to mention that. I've read that too, if the CPU isn't seated perfectly, it could cause memory issues. I read that on the EVGA forums at the beginning of the year, and just forgot. :o

Just a reseat might fix it.
 
Watch for some PPD goodness around the 4pm (EST) update. I believe today will set a record as the highest points in one day yet!

How'd you get it up to 3.43? It shouldn't be that hard--just look at my i7 overclocking thread to get an idea of what stuff should be set at. Most you can leave at stock except the Vcore, which for a moderate 3.8 or so would need to be at 1.25V or so for safety. It's after 3.8 that things get difficult.

I used a template.

That's exactly the problem. Vcore? My BIOS has 5 Vcore settings...:confused:

CPU VCore ( 1.28125 )
CPU PLL VCore ( 1.8 )
QPI PLL VCore ( 1.15 )
IOH VCore ( 1.225 )
ICH VCore ( 1.15 )

CPU is what you would need to raise, ICH is the southbridge chipset, IOH is the X58 chipset. PLL voltage you wont need to worry too much about,especially for only a mild overclock. and QPI PLL voltage you shouldnt need to worry too much about.
 
So I'm already above what Jet stated as "safe".

Maybe when he gets back from caroling he'll help me bump up to 3.8 ish. :)

Basically, read some overclocking guides, as you and i both know there is no way to just give settings for an overclock as every piece of silicon is different. Basically anything under 1.36 is safe, as 1.36 is the intel specced limit for the VID of a chip(required voltage to be run at stock speeds), and anything below 1.4v should be safe on air.

I guess you're right to a point. I used someone else's settings to get to 3.4Ghz. :o

I've read through many guides, but I must have a bit of ADD. There seems to be too many variables.

The easiest thing to do? Go set everything stock, write down the settings it automatically sets, then put those settings in and turn off auto. Then go start increasing base clock a few mhz at a time until you are no longer stable, give it a bump in vcore and continue the process until you cannot get stable any longer. It takes time to get a good overclock, but in the end the results are worth it(eg- a D0 should not have to struggle at all to get 4Ghz, especially on a board with better than average overclocking features such as power design on the evga vanilla)
