Windows 7: BSOD - Frequent - impossible to fix - 90% hardware replaced!

Possibly, but not likely. The current RAM installed only drops to 685 MHz with 9-9-9-24 timings set. If the BIOS settings include a method to manually set the frequency to 666 MHz with 9-9-9-24 timings, that would reduce it to the required 1333. Otherwise, the RAM will be capped at the 685 MHz, which is 1370 instead of 1333 and would still require a voltage bump to the processor to work reliably.

I am happy to try anything to get this stable. How would I underclock the RAM?? Everything is set to "auto" - i don't overclock anything.

I also don't understand why the system runs at all if the RAM is not compatible. It hasn't crashed all day today and runs very nicely --> in between crashes :S

Cheers.

My previous post has the required steps for setting it up to work reliably.

The thing with RAM that is incompatible is it may work fine at times, but other times it will cause issues. It is very finicky as are all faulty/incompatible electronics, and it depends on whether the voltage being supplied meets the needs of the tasks for that time period.

Try setting the Memory Clock Mode to Manual and 667 MHz. Also, set the first four timings to 9-9-9-24 and the Command Rate to 2/2T/2N if possible.


You are in luck that your BIOS does allow for manually setting the frequency. Please verify in CPU-Z that the frequency actually is running at 667 MHz after changing that setting.

OK - timings adjusted in BIOS. Wasn't sure where to find the Comand rate.

CPU-Z screenshots attached. . . (SPD identical on slot 2)

Should this now be stable???

Cheers.

Looks better. We won't know if it provides stability until you have had a chance to do your normal routine for a while. Let us know in a few days how the system is performing.

Best of luck that it is now stable!!

Thanks for all the help.

Running a barrage of tests. . .

One question - how do I check what RAM/timings are compatible with a CPU?

Cheers.

Google is the best method. Do a search for the CPU and find the manufacturer's site for it. See what they recommend for the type and frequency of the RAM, and then go to the RAM manufacturers and try to find that RAM. Either search the RAM manufacturers' sites or contact them via e-mail/telephone.
