Testing Ram
 

Whats the best program to use to test Ram?

Ive been having memory dumps randomly for about 3 weeks and i wanna see what chip is faulty as i have 4 x 512mb.

i tried the microsoft one and i cant get my system to boot using it.

Thanks

The error i get is...
PFN_List_Corrupt
Stop: 0x0000004E (0x00000099,0x0000042E,0x00000007,0x00000000)

i just did this, tested each chip 3 passes each and no errors?

Anything else i can try?

Re: Testing Ram
 

Memtest is the standard ram testing software. When I got faulty memory from Scan they asked me to test with this to make sure it was faulty. If Memtest says it's ok, then it should be ok.

its doing my head in, even reinstalled windows and plonk it happened again.

Re: Testing Ram
 

when in Windows haev you looked at event viewer (start->settings -> control panel-> administartive tools-> event viewer) to see what else may be causing errors?
as well as memtest86

there is
memtest86+

memtest.org was the app I used to test the faulty memory I had. Warning, it takes ages to complete.

Run the system on 2 x512 and see if it crashes . If it does run the machine on the other 2 if all is good swap one of the sticks with one from the crashing pair if its good then you test the last stick and in theory it should crash. If it does not then you may have a controller fault and will have to use 2x512 for now

Re: Testing Ram
 

I would advise you to use 1GB sticks as I found the machine runs better using couple of gig sticks, you can pic em up cheap these days I have 3gig in my machine and the memory cost me £36.00 for 3 sticks

Standard is about 8 hours "Wall Time" as Memtest86 calls it.

Re: Testing Ram
 

If your still having memory dumps it could also be a recent driver change causing a conflict or another faulty piece of kit, after you have tried your different memory configurations if it still dosent work think of anything else you have installed since the crashes drivers or hardware then try replacing/removing them one by one untill you find your fault.

The full crash name should have some clue as to why it is crashing note it down then do a search for the crash name or number 00000159x or whatever it looks like, hope this helps you someway always a pain ;(.

i will put it on again overnight to do a full test then.

Re: Testing Ram
 

Just finished running memtest overnight, it did 10 passes and no errors.

Re: Testing Ram
 

It's obviously not your memory then. Better start looking elsewhere.

Re: Testing Ram
 

any ideas what else? checked hard disks and no probs

Re: Testing Ram
 

I just thought i would let u all know this problem has been solved, after 3 weeks of messing around i did a wipe and reinstall fully and low and behold the problem came back. I spent 4hrs going through more and more dump files and found that a file called PAV51 was the cause of it all, it was my Panda Internet Security 2008 causing it and when i put the problem into google along with file name loads have same problem. It must have been a recent update to have caused my problem tho as its been working for about 4 months with no problem and the suddenly happened.

Re: Testing Ram
 

The error refers to the page file so checking out the hard drive or moving the page file to a different hard drive might help (oops ok nm, didn't see page 2)

Re: Testing Ram
 

You could be right there, also some ram chips have trouble working together if 1 or 2 are single sided and the other 1 or 2 are double sided.

Re: Testing Ram
 

since uninstalling the problem is cured, i dont think its ram as the ram has been in the system since i built the system at easter 2007 and never had any problems.

Re: Testing Ram
 

Glad u r fixed.
