memory testing criteria

[yoshimomori]

Hey guys

I was wondering how manufacturers / review sites test stability for overclocked memory modules? I see a lot of review sites that will increase the mobo voltage or clock speed, and say "this module ran fine." But dont you have to keep the modules at that stress level for thousads of hours to make sure that the modules wont crap out after xxx amount of minutes/hours?

And, are there any specific programs/tests that can evalauate and give a score for a memory module? I mean, there's MemTestxx to test that it works, and there's Benchmark programs to test the computer as a whole, but are there any that test specifically the memory module?

Also I see a lot of review sites that say "we increased the mobo voltage to 2.5v and module A ran fine, and module B ran poorly. Hence module A is better" Is that more or less the standard to judge if one module is "better" than the other? I mean, if the user was just running the mobo at normal 1.8V, conceivably module A and B both perform at more or less the same level. So, are there any other criteria that people should keep an eye out for in reading review sites to determine if one module is better than the next?

Thanks!
