I need some help with my first OC

post #1 of 4
Thread Starter 
well i just built a new computer
EVGA 75i FTW
Intel Q9300 2.5gig
Rosewill RCX-Z775-SL cooler
4g Corsair Dominator
PNY 9800gt 1gig
WD 500 gig HDD
Antech truepower 550

Ive never overclocked anything before so I was wondering if anyone else out there had this set up and what settings are you running, or just some suggestions from others on how to maybe get this baby around 3.0-3.5 gigs?

I am wanting to know also. I will watch this. I am having a hard time with my Q6600 and this Mobo.

Well, first thing is first. Get into your BIOS. Q9300's don't OC all that well as they have a very low multiplier (7.5 max). Make sure the multiplier is that high for best effect. If you can't get 7.5 and are instead getting 7, there is an option called "n/2 multiplier" or something to that effect, just enable it. Now go find C1E, EIST, Speedstep, and Thermal Management control, and disable all of them.

To figure out what your chip is truly capable of, we're going to max out the voltage and keep amping up the FSB until it crashes. Put your vcore (or CPU voltage) to 1.35V DO NOT GO OVER THIS VALUE, YOU WILL DESTROY YOUR CHIP. Make your RAM voltage 2.1V, and your northbridge voltage 1.3V (it can be slightly higher if you can't get it exactly there). Make your Dominators run at a 1:1 ratio with your FSB, should be called "400/800" in your options.

Now, crank up the FSB to 425, your board should be able to handle it, but we don't know about the chip yet. Boot up.

If your PC doesn't turn on, doesn't make a single, short beep, and/or doesn't boot into Windows, the OC is too high for the chip. Turn off the PC and reset the CMOS by taking out the battery (looks like a shiny nickel on the motherboard) and put it back in after 30 seconds.

If you boot, download CPU-Z, Real Temp, and Orthos. Boot up CPU-Z and make sure your voltages and speeds are what they should be, etc. Look at Real Temp, you idles should be in the 30'sC. Select "Small FFTs" in Orthos and let it rip. Monitor your temps closely for the first 10 minutes, if they get into the high 60'sC you're in trouble...stop it if it does and bump down to 400FSB instead and retry. If your temps are manageable, let it run for a good 4 hours or so. After that, you can decide if you want to go for an even higher OC, or keep the one you have, because you're now stable

I hope this helps, good luck!

I tried your recommendations, I had to unlink the memory cause with those settings it was at 1400 mhz, what about the voltages for the spp and nf200?
