Can someone recommend me some OC settings?

[desicrator]

I Have a phenom x2 550 with arctic cooler 64bit.
Radeon 3850 HD
2gb ram, single chip but i am getting another of the same 2moro.
asrock n68-s
550w PSU.

Air cooled with 3 case 120mm fans. I live in scotland so very cold climate.

Playing CoD4 my gpu max's 45 degree's and cpu only hits 27

If someone could recommend settings to try for multiplier / fsb aswell as core voltages etc. as i havent really done any overclocking since my first athlon 2800+ which was just increasing by 200mhz.

thanks

These chips have unlocked multis right?

Without knowing your BIOS all I can tell you is to raise the CPU multi to get your o/c.. check for stability using something like LinX or Prime95, if it is unstable, then re-enter the BIOS and bump up your Vcore one increment, then test for stability again, keep doing this until you find stable settings.

I am able to change settings with asrock OC tuner, while in windows however i dont know what to change.


Ok at current, i have 1.50 voltage. 19.5 multiplier and 206 fsb = 4015 mhz running, i have done the 32m super pi calc thing which gave me a time of 17mins summit. with no re crashing or bsod. what shud i do with pci-e bus?? or ram.

I wouldn't bother o/cing RAM mate, also Super PI won't really stress your chip as much as Prime95 or LinX will, I can run Super PI with my processor clocked to 4.6GHz but as soon as I fire up LinX or Prime95 my system crashes instantly..

PCIe clock should stay at default 100MHz as well, there isn't any point in o/cing that as you won't see any performance increase, although some people do say raising it to 101MHz can help stabilize your o/c.

Also, o/cing from Windows isn't recommended tbh, using the BIOS is much better, but it's your choice at the end of the day how you choose to clock your chip.

when i go into bios to set the multiplier manually it gives me other settings to change but i have no idea what to put on them, if any1 can give me a hand.

thanks

For your RAM timings, the only ones you really need to worry about are CAS Latency, tRCD, tRP, tRAS, and Command Rate, if you set these to the ratings of your modules that's all you need to worry about. you know the numbers you will see on the side of your RAM, like 5-5-5-18-2T.

If you just raise your CPU Multi to what you had it set to in the ASrock o/c software, and then bump up the Vcore to the same value you used in the windows app, then save and exit, and you should have the same o/c as you had before.

Also, if you are only overclocking with the CPU multiplier, then you should bump the HT Bus Speed up to 1000MHz instead of 800 as it is set to atm, however, if you intend on using the CPU frequency to o/c and you start experiencing instability, then you should lower it back to 800MHz again, but with this chip, you shouldn't need to use the CPU frequency to o/c, the multiplier should be all you require to get a nice o/c.

Also when you start using CPU frequency, it not only clocks up your chip, but your RAM and Hypertransport frequencies as well, and this can lead to instability to.

This BIOS is pretty much identical to my old ASRock K10N78 mobo.

I never had a CPU with an unlocked multi, as I had a 6000+ X2, so I used to set the HT Bus Speed to 800MHz, CPU Frequency to 235, use the DDR677 setting for memory clock instead of 800MHz, raise Vcore to 1.45v, and bump NB voltage up a couple of increments, and keep my processor on the 15x multi, which would give me a nice little o/c of 3.5GHz..

any time i try to set voltages and multiplier within bios my pc doesnt boot to post. i need to reset bios to normal. any idea why??
