Advise on Corsair XMS2 with AMX Athlon X4 640

post #1 of 2

Hi all,

I currently have the following hardware:
Mobo: GA-MA770-UD3 rev 2.0
Ram: 2 x 1Gb XMS2 CM2X1024-6400 5-5-5-18 @ 400Mhz
2 x 1Gb XMS2 CM2X1024-5400C4
CPU: AMD Athlon II X4 640
Stock CPU cooler
GPU: Radeon HD5450 with passive cooling


I currently have the following overclock: CPU Frequency 230 (200 stock). Everyting else is "Auto" and the memory is set to unganged. This uplifted my PC Mark score from 994 to 1126 i.e. 11.8%

.................Stock...........OC (230)
CPU...........3299...........3802
RAM...........865.............967

CPU temps under load = 54C


This machine is not used for gaming but for desktop apps and the occasional google earth etc.

I am soon to be getting some more RAM (awaiting delivery) as I need 6Gb for running some VMs. I purchsed 2 x 2Gb XMS2 CM2X2048-6400C5 to go along with the faster pair of 1Gb sticks above. I am hoping to see a small performance increase by ditching the slower 5400 sticks (I expect about 5% on the memory speed). I remember trying settings above 230 for the CPU frequency but I don't think it worked. I have not got the RAM just to get the uplift from 5400(5300) to 6400 as I know this is quite minimal.

The question I have is.... when I get the new memory and then it's all 6400 are there any tweaks that I should be looking to make to the timings of the RAM on this particular Mobo?? I don't what some insane OC but just a modest OC that is nice and stable and does not require a new PSU or more cooling. I dont want to look at faster CPU's or Mobo's or memory but, rather, id just like to get the best out of what I have. I understand that the XMS2 memory is quite good and I guess I need to know if it is running at its best out of the box or does it require a bit of tuning?

Any help and advise greatly appreciated.

Cheers,
Paul
