Memory Question overclock q6600

Hey all, I tried to set memory ratio to auto and overclocked FSB to (1333?) anyway, the outcome is a no-boot. My question is, does mixed memory timings mess with overclocking?

System:
Intel Q6600 2.4 Ghz (for now)
P5N-E SLI nVidia 650i
6 GB pc6400 800 mhz (this is the hard part; part muskin 5-5-5-12, part corsair 5-5-5-18)
9800 GTX+ XFX

You can not set memory ratio to auto. It should be 2X.

You will probably also need to set the timings manually. you can try with the quicker if you want, but may need to run the mushkins at the timings of the corsair. Also check voltages as they may need different voltages.

I run 2 different generations of crucial RAM and can thankfully run at the faster timings on both sets with one channel over-volted and the other under-volted.

You'll have to set manually but it will take time to reach their optimum speed.

That motherboard is not very good for overclocking. I had Q6600 on it and it would not boot anything higher than 2.7 and was unstable over 2.5. Now I have the same Q6600 running on EP35-DS3P and it runs 3.2 stable all day long. I even boots @3.6 but gets too hot to test prime 95 stability for long period of time.
If You still want to try Your m/b. Set RAM voltage to 2.1-2.2V, timings to 5-5-5-18 and speed to 667. After You reached desired / maximum overclock reduce voltage if You can and tighten timings. Also yo might need to increase voltage on CPU. I have mine raise dfrom 1.325V stock to 1.375

nope. tried lowering RAM speed and the voltage. CPU will not budge after 2.6 ghz. Thinking of just using one of the memory sets for the overclocking to focus on, but my goal is just to have a 3.0 ghz q6600. seems like its impossible for me. Also can someone explain the process of adjusting voltages for different channels? haven't tried that yet.

Ps. I do have a rocketfish CPU cooler with copper pipes and aluminum fins. idle is 45. don't think temperature is a problem.

Probably Your board is holding You back. Like I said before I had Q6600 on P5N-E SLI and could not get stable over2.5 or to boot over 2.7. Now I have the excactly the same Q6600 moved to EP35-DS3P and it works all the time at 3.2 and can booot at 3.6 but gets too hot on 3.6. You should get P45 or at least P35 board for overclocking. If You want ot keep SLI capabilities then 790i ultra but thta is expensive. By the way I am also using mixed Ram an no problem at all.

cpu should 1.47v with intel chipset for cpu - with cpuz and prime 95 you want 1.44-1.55v at max output
memory voltage = 2.05 to 2.1 while you can go up to 2.15 i do not recommend it
for 4-4-4-12 use 2.1v for 4GB - gskill pc8000 works everytime
some memory can run as low as 4-4-3-10 timings but 4gb is tough 2gb is easy

3.6ghz! as written over a year and half ago

"Our new air cooled systems will run 3.6ghz with a quad core! WSZ X4 3.6 Vcore 1.42v p35 chipset. "

that me quoting me!

Alright so it is no longer memory but only a motherboard issue. I dont plan one pitching in 200 dollars for a new one when this one is already recent enough (grrr no overclock) K thanx maybe ill just get another card for SLI and that will do the extra ten FPS for FC2 and Crysis.

Also I have been running these games on a 50 inch HD Plasma TV XBOX 360 Style. In case you guys are wondering why i need so much power in a computer.
