I am trying to overclock my Q6600 b stepping rev go... on a p5k deluxe mobo. For some reason the overclock will not take hold, I have no clue why. First off my I cannot change my multiplier, I cannot select the option. I have set my fsb strap to nb at 400. I cannot adjust the fsb frequency, as it is locked. I am not no expert at this, and do not know what to do next...all I know is the only setting that I have successfully made (the fsb strap to nb) has done absolutely nothing to overclock anything...please help!
 
The Boot strap isnt the way to overclock. There should be a frequency adjustment that allows you to change frequencies 1 mhz at a time. That will allow you to overclock the chip.

I hear what your saying, but I cannot adjust the fsb frequency...I cannot select the option. Why would that be?
 
With Ai Overclocking set to Manual you can't change CPU Ratio Control to Manual, or change the FSB Frequency option using the +/- keys on the NumPad?
 
I got it, thanks for the help. I figured out that you have to manually input the value. So far I have it running seemingly stable at 3.6 ghz...at least it has passed 6 hours of prime 95, during that time (according to the asus probe) My highest temp that I recorded was 49c on air cooling. Funny thing though...according to CPUZ my core speed under load is only registering at around 2402.00 mhz...that can't be right. Before I overclocked my windows performance rating for the cpu was 6.8...now it's 7.3.... How much further could I go on air? Thanks
 
You may have to turn off SpeedStep to stop it from down-clocking during idle.

C1E and speedstep m8. you may bet 3.8ghz out of the old girl but you wont get more then that, hell back then 3.8ghz was a good oc. most q6600's would do 4ghz back then but now the q6600 batches got so bad that 3.6 3.8 was good.
 
Is speed-stepping called anything different? I cannot find speed-stepping in my bios
 
I do not know how to do that, I have never figured out how to take screen shots.
 
Assuming you're running a newer OS like Win7, use the Snipping tool to outline the pic. of CPU-Z open to the CPU tab. Save the snip as a *.jpg, then just attach it to your next post.
 
I went back into bios, and changed some settings. I set the multiplier to 8, the fsb to 433mhz, the pcie to 100, and the cpu voltage to 1.4500...ran p95, for about 40 min until I got my first error, and re-booted. after the re-boot I got a memory read error. I am running 4 gb of corsair dhx 800 mhz. Should I try increasing the dram voltage? In bios the ram speed reads 867mhz with 433 fsb...is this dangerous for my ram? Funny thing about the ram speed reading in bios, is that on cpuz my dram frequency reads 433mhz...is this normal? Capture_zpsc4685c5b.png
 
The screenshot was from the run that error-ed... what d-ram voltage should I start with?
 
Ok, I have set the voltage to the rated 1.8 volts, I also set the timings to their rated values 5 5 5 15...I will proceed with another stress test.
 
Ok, That didn't go so well. here is a screen shot of what happened during the torture test. How safe is it to increase the volts on the ram past it's specs? I have a ram cooler, if that helps...I just don't know how well the ram I have overclocks.

You are fine to increase it, if it is rated for 1.8 try 1.825-1.85 and try again. What speed is the RAM running at now after the increase? 866 instead of rated 800?
 
My memory is running at 867. Do I need to come off the fsb? Raising the voltage did make it more stable. I ran p95 for a full 2 1/2 hours before I got the same error again, so I brought the ram up to 2v, and ran it for about 2 more hours, and got the same error again. So I decided to test my stability with Crysis, since it is the most taxing game I have at the moment. I set all the graphic settings to very high...and about 3 minutes into it...I had a blue screen. I thought It was due to system instability, until the re-boot (squiggly lines through my screen, and a not so promising response trying to re-open Crysis on re-boot..no compatible vga device, and following direct x fatal error, couldn't even open the nvidia control panel) my 8800gts is not among the living anymore. I confirmed this theory by installing my back-up 8600gt, and have played about four hours of crysis, with no sign of any kind of instability...of course the in order for the game to even be playable with the 8600...the settings have to be medium or below. I guess it's time for a new video card anyway.
