Well first off I'm new to overclocking and would like some tips.

CASE: NZXT TEMPEST EVO
MOTHERBOARD: P5Q PRO TURBO
CPU: C2D E8500 CO @3.16mhz
CPU COOLER: COOLER MASTER HYPER N520
RAM: MUSHKIN (996527) 4x1Gb DDR2 800MHZ 5-5-5-12
GPU: VISIONTEK HD4890 OC EDITION (ZEROTHERM COOLER EDITION) @950/1050 IS THE FACTORY OVERCLOCK
HDD: WD640GB 7200RPM, WD 320 5400RPM, HITACHI 500GB 7200RPM
Im using Artic Silver 5 as well.

Ive gotten to 3.362mhz stable but want to go higher (temps under 60c @ load) while running Prime 95 and using the TurboV software that came with the mobo. My cpu/ram ratio is 5:6 and my ram is at 424.8mhz on that oc. i would also like to know how to make my cpu/ram ratio something like a 1/1 or closer. Im running everything on auto in the bios except my ram timing . It runs at 5-5-5-18 on auto and i had to change to the proper timing to 5-5-5-12.How should i go about raising voltages and fsb when developing the overclock in TURBOV
If you need more info about my rig just ask.
Thank you for any help.

An E8500 should be able to go pretty high, perhaps limited by your ram. However I would recommend getting a good aftermarket cooler before you go any further.

I have an E8500 running at 3.8GHz, meaning the system bus is set to 400MHz and it runs my ram at its limit of 800MHz. If I had bought better ram I could probably have gone a little bit higher, maybe I could anyway, but I'm content at this level.

I think there is a conflict of terminology here but I'm not sure I can explain it correctly. I think when we say "run the ram at 1:1", it is really running the ram at twice the bus speed because it is DDR2 ram. So while you are running your ram at 424, you should be running it faster.

CPU-Z uses memory frequency. The BIOS uses memory clock. DDR2 RAM remember? Each bus cycle generates 2 RAM clocks.

A lot of the confusion comes from the fact that everyone seems to use these terms slightly differently. That's why I am very careful to distinguish between FSB frequency and FSB clock.

You can frequently push RAM a little farther by increasing the RAM voltage to 2.2 volts (don't exceed) and relaxing the timing a little.

my ram is rated to run at 1.8v so 2.2 is not going to happen with this mushkin set.
here is a newegg link for the ram

how do i relax the timing as you would say? 5-5-5-12 is the stock timing.
would i be better off just overclocking my ram only and how do i go about that procedure

and whats wrong with my cpu cooler i know its not the best but its not stock
