How can you test if RAM is stable after OC?

post #1 of 16
Thread Starter 
I ran prime 95 yesterday for 13 hours to make sure my CPU oc was stable. During that test my memory was running at 750MHz, with 1.9v (underclocked and undervolted). So I figure now my CPU is squared away time to OC the ram. My ram's stock volts are listed on G.Skill's website as 2.0-2.1. So I put it at 2.1, and set the speed to the next highest availible DDR2 938MHz.

So far it seems ok, as it hasnt restarted, but how can I stress test them? Would prime 95 work for testing RAM's stability?


Thx

yes, just make sure you do the blend test for several hours.

If you memory was the least bit unstable then Prime would have failed.

Ok thanks, turns out 938MHz with 2.1v was unstable, it crashed.

One more question, how many volts above stock is it safe to go with RAM? I just put it at 2.15 after it crashed at 2.1. I cant loosen timings, they are at 5-6-6-18.

Heres my ram. http://www.newegg.com/Product/Produc...82E16820231073

Nice job, though....*****.


USE MEMTEST86.

Well I ran prime 95 for 3 hours and no restarts, so I assume my RAM is stable, although I havent used memtest yet.

What are safe volts for DDR2 RAM with stock volts listed as 2.0-2.1?

You need to run it for at least 6 hours to ensure maximum stability, and even then you have a small chances of running into instability

It depends on the chips, I've seen D9's running at 2.5v 24/7 just fine(with active cooling), don't know about the others though
