Can I OC the memory before the processor?

post #1 of 20
Thread Starter 
I want to OC my memory because its the lowest score in my vista experience index.

I've never oc'ed it or changed its timings or whatever so I could use some help here.

Yes you can and for your motherboard, if it is like mine you have to press control-f1 to mess with the timings under MIT.

ocing your memory wont help at all. just like my E8400 at 3.0 is at 5.8 on the index but at 4.4 its still at 5.8

At most, you can tighten you timings to increase efficiency..but this will help only a little. A large benefit from OC'ing is the additional bandwidth your mobo and RAM get from increased FSB.

ie- If you want to see for yourself, run an Everest Memory Read, Write and Latency test and record the results. Then use a different divider in your BIOS, to keep your CPU speed ~the same as stock, and run your RAM at stock speed also..load windows and re-run.

*lowering the multi also boosts bandwidth for memory as it increases NB speed.

kinda confused on this part "to keep your CPU speed ~the same as stock, and run your RAM at stock speed also..load windows and re-run"

why would I run the ram at stock to test it for a 2nd time?

Because raising the FSB alone will increase bandwidth for your RAM.

ie - assume there is 1066mbs bandwidth available right now, with stock settings all around..and with stock timings your RAM gets, say 70% bandwidth efficiency... then..

1066*.7 = 746mbs for your RAM throughput [the numbers are irrelevant..just the theory and how it applies are actual.]

so when you raise the FSB to 400mhz and run the RAM at stock speeds again.. you get...

1600*.7= 1120mbs

..rough example, but that is the 'jist' of it. You did say you were not interested in an OC for the CPU, so..

Keep your CPU and RAM at stock and raise your FSB. Test it, you will be surprised.

Your ram may not be set to the correct timings. Check the GSkill
website for default timings.
