Should I keep 12GB or reduce it?

Well after my last "overclock" I spent four hours staring at my computer and restarting it every minute. Luckily I have not blown up my computer since yesterday. However I do have a minor dilemma.I have 12 gigs of ram. Yes I know that is a little much, but half the ram was free so I figured why not. The problem is half the ram is at 1333 and half the ram(replacement) is at 1066. Should I keep the 12GB or remove the lower performance ram?

EDIT: Yes I edited it

Just leave them all at 1066, you don't see much/any difference in overclocking it.C_Rule

Well it would come down to what you use, if you aren't using the 12GB to your advantage and you don't plan to anytime soon, then sure, sell 6GB of it off. The performance differance is minimal between 1333 and 1066.

You could underclock the RAM to match, but I'd get rid of it. RAM should be the same brand, same kit and same speed.

all my ram is exactly the same except for speed.Brean24

Then underclock it. Problem solved.

if your trying to overclock keep the 1333 for a little head room and take out the 1066 that way you can actually have a stable clock when stress testing.

I bet you won't see much of a difference whether you go with 6GB of 1066 or 6GB of 1333 or 12GB @1066 or 12GB@1333.

I say remove the 1066 RAM. Also, having all the DIMMS filled can cause instability when overclocking. It will add stress to the memory controller which is integrated in the i7 cpu's. If you are doing tasks that take advantage of all that extra RAM (like 3d rendering or video editing) then you will want to keep all that RAM. But for many uses, including gaming, 6GB is more than enough.jtcraft
