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.

Re: Testing Ram

as well as memtest86

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

Re: Testing Ram

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

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 ;(.

Re: Testing Ram

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