- DDR Tester?

then restarting, on its own. I have replaced the MOBO and CPU and
PSU. I have changed HDDs. The machine still crashes. Now I am
thinking my DDRs are failing. I have two, one 512 and one 128.
I want to run a diagnostic against the DDRs, but I can't find a free
one via Google.
Can anyone point me to a free diagnostic that I can download and run?
That is any good that is.

If it finds any errors at all...the RAM can generally be considered as bad.
RAM test will run indefinitely...but if it does not find any errors after a
the RAM is probably OK...
If the RAM tests ok.it might still be slightly marginal..the machine may run
OK is slightly underclocked

Re: Re: Re: DDR Tester?
Well - I have tried both DDR testers, and neither showed any errors. I
have two machines with identical DDRs, and the second machine has
never crashed (as yet anyway). So I switched DDRs to see if machine
two will now crash. I also have disabled auto restart in both BIOS's.
We shall see I guess.

www.MemTest.org (newer version of MemTest86, called MemTest+)
www.GoldMemory.com (shareware that nags until you pay)
I've had a couple of modules pass MemTest86 but fail Gold Memory, and
vice-versa, so I always test with both diagnostics, and I run each one
overnight because some errors can take hours to show up, in one case
4-5 hours. Also most BIOSes set the 1T/2T command rate to 2T, even
when the module is rated for 1T and the SPD default timings are
chosen. So when a module is rated for 1T (almost all are), I manually
set the BIOS to this. 2T won't cause a noticeable slowdown, but for
testing, 1T seems to reveal errors a lot faster.
