how much to memory timings affect performance?

[eddyc]

Hi all,

I have 4GB of OCZ obsidian running at 1600 Mhz (at least I think it is 1600 - it says 800 in cpu-z memory tab but you double that right? ) with 9-9-9-24 timings.

Would changing the timings improve performance?

What changes should I make?

I assume that I should use memtest to check if any changes have destabilised the ram?

Thanks for that link. Really interesting.

I think I will try reducing the timings a step or two just for the sake of it but to be honest it kind of sounds like it does not make all that much difference apart from in benchmark tests.

Since I have 9-9-9-24 I guess the next step is to try 8-8-8-22?

Cheers for all the help.

Weird.

Do you have your memory over voltage settings in the bios running at the correct level. I only realised recently that this is not automatic. You have to find out from the manual what the correct setting is and then set the mobo to provide that.

My ram is running significantly under volted but it seems to be happy so I let it be

I tried to take mine from 9-9-9-24 down to 8-8-8-22 and it failed. I only took the V up to 1.6 (the rated v of the sticks) though.

How well does ram deal with higher voltages than they are rated for?
