Does anyone understand RAM timings?

My memory timings and uncore frequencies are holding back my core i7 overclock. However, I picked a poor motherboard and I can't simply adjust the multipliers, I get to do it all by hand I don't have ppm voltage control or any control over the qpi frequency other than directly setting it. When I go into manuel, this is what I see:

Performance Tuning Mode: Manuel
Uncore Frequency: 2133 mhz
DRAM Frequency: 1066 ghz
tCL:7
tRCD: 7
tRP:7
tRAS: 20
tRRD: 4
tWR:8
tWTR:4
tRTP:4
tRFC: 59

When I used these manuel settings I got to post 4 clocks high on my baseclock, but it wasn't stable, so for now I just have it at auto. But remember, this, vtt core voltage, and ram voltage are the only relevant controls thatr I have access to. I have no multipliers accesible for this I need to simulate bringing down the multipliers in order to overclock the base clock high, but I don't know what I'm doing. I can't type in my own DRAM frequency: I have (off the top of my head) 800, 1066, 1333,1600, 1866and I thinks that's all. HELP!

Are there any special rules about that, like one having to be x amount more than the other, or one having to equal the other?

wouldnt really bother - there SPD timings etc - internal delays on the ram, there set by the manufacturer as working and tested defaults

what motherboard do you have?

So by easing up on the first few timings, these components will require less voltage?

Assuming this is for games, it is possible that your CPU is more than adequate for your graphics cards and overclocking your CPU would do nothing.

In the simplest case of an older, single core CPU you can test this by monitoring Task Manager (CTRL-ALT-DEL). Leave it running in the background during your demanding games. If it never reaches 100% then your graphics card(s) is holding you back. It's slightly trickier with multi-core. If none of the cores/threads show 100% there's no need for overclocking. If a single core shows 100% you might see a benefit but it's not certain.

You say your RAM is holding you back?
Based on what you describe I'd be surprised if your RAM is holding you back. RAM is rarely the limiting factor, especially in games.

Optimal RAM bandwidth is needed mainly when your CPU is completely maxed out (all cores/threads). I doubt any game would max out your memory.

How do you even know your RAM is maxed out?

My advice is to leave your CPU at a reasonably stable 3.2GHz and enjoy your system. This fascination with getting the maximum theoretical performance (i.e. not necessarily used by your software) at the expense of fan noise and stability baffles me. I'm not saying that's what you are doing, though.

My RAM is 3 sticks of 2GB DDR3 1600 mHz.

I have 2 gtx 260 core 216 w/ sli, and I think my gaming performance is pretty good, but I'd also like to make the processor fast for benchmarks, and, simply because I can

Alright, i'm going to go play with my memory timings. I'll let you guys know how it goes.
