Re: First OC Q9550

You need to start over. Please go into the BIOS and load and apply optimized defaults, then set your ram voltage only and save/apply/reboot BACK to the BIOS. You will then need to set all your changed settings again as they will be reset. This includes, and do not forget especially if you are running RAID, SATA And Disk settings in Advanced BIOS, and Integrated Peripherals page.

I can help once you do that, you cannot start overclocking from Fail Safe settings as many hidden per hardware settings may be incorrect, as well as ones I can visibly see that are.

Please see this thread for all Optimized Default steps needed if you are running RAID >>

Re: First OC Q9550

Okay. Reset to Optimized Defaults and set DRAM Voltage to 2.00V. Not running raid. It's about midnight here, and I've got to sleep. Check back tomorrow. Thanks again.

Re: First OC Q9550

Try this for 3.2, I give a few ways trying to keep your ram above 1000. You can also use CPU multi 8/8.5x400 FSB but your ram will need to run 900-960 that way >>>

Robust graphics Booster----------------------Auto or Fast

Fine CPU Clock Ratio-------------------------+0.5
CPU Frequency------------------------------3.187 (425x7.5)

OR

Fine CPU Clock Ratio-------------------------+0.0
CPU Frequency------------------------------3.150 (450x7)

Clock Chip Control

CPU Clock Control---------------------------Enabled
CPU Host Frequency------------------------450 MHz

Re: First OC Q9550

Thanks! Going to give this (425x7.5) a try. Before I start, I thought I'd post my stock fan temps at idle. Will continue with your settings unless you see a temp problem.

[Lsdmeasap]

Re: First OC Q9550

Those temps look fine, but you do need to Disable C1E and EIST still of course, just incase you are overlooking that when you get started.

Good luck and keep us posted on your progress and tweaking results

Sounds good.

Will do. Thanks again.

Re: First OC Q9550

K, Good luck and see ya soon!

Re: First OC Q9550

how did your OC work out? I got the same CPU and was wondering how far I can push it and have it run safely!

[boonalong]

Re: First OC Q9550

I stopped at 3.4, I really just wanted to get it above 3.0. Everything's running smooth. Around 35 degrees idle on air. Around 58 degrees 1 hour with Prime95. I've seen a lot of guys push theirs to 4.0 on air, but they have better coolers than mine (Arctic Freezer Pro). Thanks for reminding me. Lsdmeasap, sorry this is late, but thanks for getting me started.

Re: First OC Q9550

Nice thats what I m looking for 3.4 3.6, can you post your bios setup please that would help me get in the right directions to start OC my CPU.

Thanks
