Ello!

So I've had the Corsair XMS2 DHX (TWIN2X4096-6400C5DHX) 4gb kit for a while now and decided to upgrade it with some more.

Went looking around for what worked, and the same ones were still very pricey. So I've found these almost identical Corsair CM2X2048-6400C5 4gb kit.

Now I've added them and the performance isn't really improved.

This is with the added RAM

And with my original RAM

Timings on the XMS2 are 4-4-4-12 and the CM2 are 5-5-5-12, but are both set to auto in bios.

Now I know you shouldn't mix RAM together, but these seem like identical RAM, is there some bios settings or timings that I need to change to get it up to speed?

Thanks a bunch.
 
Solution
Try increasing DRAM voltage + 0.05 and see if it helps, for basic read, write, copy you aren't going to see much difference as it uses little of your DRAM
