"Memory allocation error"

JuanTutors · 2009-01-29, 02:21

I just upgraded my ram. I gave it 2500 MB ram for stage 2 testing, and I'm getting "Memory allocation error" over and over. Does that mean I have faulty ram AGAIN?

I don't know if this is relevant, but my old ram was four 512K sticks of dual channel ram, and the ones I put in just now are 1GB non-dual channel ram.

//EDIT: it doesn't start working until it gets down from 2.5GB allocated to only about 1.1GB allocated for stage 2.

No. Are you using 25.8? It is linked with the /LARGEADDRESSAWARE option that lets prime95 access more memory under Windows.

I am using 25.8. I don't know what the rest of what you said means

Memory allocation error is not a sign of bad ram. It is a sign that prime95 is having difficulty getting the OS to allocate memory for prime95 to use. This could be a program bug (or not).

Is there any way to find out? I just got the RAM. Could be faulty, but I don't know.

Exit prime95. Restart prime95. Run Torture Test. It is better at finding memory problems than P-1 Stage 2.

I've been running a torture test with two threads since last night, all passed. I have a dual core proc. Should I create another copy of prime95 and start another torture test?

No other torture test is needed. After 12 hours, you are looking pretty good.

I think your trouble comes from the different memory-sticks.
As far as I can see you are running atm 3 sticks 512MB supporting dual-channel and 1 stick 1024MB not supporting dual-channel. I would try another memory setting:
bank0 512MB
bank1 512 MB
bank2 1024 MB
bank3 empty

you will loose 512 MB, but I think the memory allocation errors could be solved.

best regards,

Matthias

btw: it is not needed to run another instance of prime95 for another torture-test

Even if you get it working, you may find that your overall performance is better with four sticks of 512MB dual-channel that with a mixture of RAM types, even if the mixture is larger in total.
