What memory timings in BIOS should I adjust?

[petergomes]

Hello everyone,

I swear I get about one e-mail a day asking which memory settings in BIOS should you adjust.

 

Example:

You are running some Corsair XMS XL Memory. This memory is rated at 2-2-2-5 memory timings. This is where people get stuck. ASUS for example gives a million memory options in their BIOS, but you really only need to play with the 4 mentioned by the package. These four are CAS-tRCD-tRP-tRAS.

 

 

So for this memory you would set

 

CAS-tRCD-tRP-tRAS

 

2 - 2 - 2 - 5

 

You are done! All the other settings should be left on "AUTO" and the SPD on the memory module will auto-set them for the value pre-programmed from the factory!

its not worth the hassel of messing with RAM settings, i would look in the the bios for "optimise settings" set to that then exit and save.

 

overclocking unless your into high spec games shows no return.

That depends, sunny. I'm running my Opteron 165 (spec'd at 1.8GHz) at 2.7GHz. That's a 50% increase in raw speed over stock and even my wife notices the difference.

I do agree that messing with the memory will pretty much show results only in benchmarks. I've done just as you said with memory and left it up to BIOS.
