Folding errors seemingly attributed to RAM

post #1 of 16
Thread Starter 
As the title states I keep getting errors that don't make sense it seems.

Running SMP on a Linux VM with Linux Mint 11
Last night I got an Error 7B and today an Error 72.
When these errors occur other programs are rendered unresponsive such as Google Chrome or my DC++ program.

Usually 72 is attributed to an unstable machine, but the machine has been stable through 12 hours of Prime 95. These errors are only occur when using VMWare. I've reinstalled VMWare multiple times and have used multi distros. I'm thinking this is attributed to my RAM but after running Memtest I have no errors after numerous passes.

I've put excess amounts of voltage in my system to help verify that my stability is there but I just can't seem to find the problem.

I've also reinstalled Windows 7 to verify that wasn't the problem.

Are these errors in the folding logs and losing a WU or are they BSODs?

These are in the Folding Logs. No BSODs have occurred because of these.

I would highly recommend running memtest overnight to check for errors. From a quick google both of those errors look like they are related to ram. Try each stick seperately with a couple hours of folding and 12 hour run of folding.

Folding has a way of turning up even the slightest instabilities in systems but can take a while. Same thing goes for memtest. It might take hours before the error is found.

How many hours for each stick in memtest?

I've done this before but definitely willing to do this again

This is def a ram error. Either the speed is too high or the timings are too low. This could also be attributed to a bad NB OC.

If your using VM Ware 3.0.0 i feel your pain

I lost the will to live along time ago using VM software, because of its unreliable nature.
Installing a Dual boot linux / windows environment was one of the best things i ever did.

Honestly if you want an almost 100% answer you are going to have to run it all night or at the very least 6-7 hours. It might take hours for an error to pop up but skimping on the time could miss bad sections.

Running my NB 1.38v @ 2600 MHz

Ram is sitting at 1350 Mhz with 9-9-9-24-2T and 1.6v , which is underclock

Looks like I'll be running some memtests! I'm folding right now on one stick just to test that while I do some work.

How is this going?

is your bios at its most current version?

I have found that my 2133 DDR3 can sometimes cause errors
running it 1866 has helped until i upgraded my bios to a stable version.
