    I'm still working on this OC as time permits. I've been successful in nudging the FSB frequency up to 377MHz with gives me a CPU core frequency of 3.2GHz on my Q9550. I've done this without having to increase the Vcore on the CPU from its stock 1.2500volts.

    My concern as I head towards my desired 3.4GHz OC is the temperatures I'm generating. I've installed the latest version of CoreTemp which I use to monitor core temps as I run Prime95. I run the large FFT test option that is supposed to create the greatest amount of heat etc.

    After a couple of hours of running Prime95 all four cores register 71c to 73c prettty uniformly. This seems a bit high and I don't like it. Case temps are running about 31c and room temps are 21c. I have a concern about my present temps and I'm greatly concerned that my temps will redline if I have to increase Vcore as I keep rasing FSB frequencies. After all, heat increases exponentially as voltage increases.

    I have an ARCTIC COOLING Freezer 7 HSF installed with Arctic Silver 5 paste in a Lian-Li PC-201 server case. I've checked and reseated the HSF to make sure the contact is good. I believe I've done a good job of installation but I really don't like the cheesy mounting method used on a Intel socket 775 motherboard. I know it's not Gigabyte's fault - but I still think the mounting method is cheesy.

    Anyway, I digress. Any thoughts about my core temps and how to bring them down?

    Thanks.

    Looks like you will need a larger heatsink then. Maybe Thermalright Ultra 120 or Tuniq Tower, or Xigmatek 120

    Whats the idle temp, and are you sure you did not use too much paste?

    That is hot for stock voltage for sure, I did not even get that hot at 4Ghz with my old Zalman 9700 with 1.3+ Volts. Maybe 60's

    On water now, but That just seems pretty hot at those volts to me. Maybe that cooler isn't up to snuff to cool a Quad

    Thanks for the quick reply and the suggestions on the larger HSF.

    I'm confident that I didn't use too much silver paste. I'm pretty careful about reading and following the installation instructions.

    Idle temperatures right after POST and booting to Vista are in the mid 40s. Idle temps after ending an instance of Prime95 and giving things a chance to stabilize are even higher - 50s.

    Any quality heat sinks out there that you are aware of that have a more positive connection to the motherboard than the little plastic clicky-things that came on my Arctic Cooling HSF. I'll have to unassemble my whole computer and take the motherboard out (again) to mount a new HSF so I may as well look for something that mounts through the board to a plate/bracket on the back.

    I really don't want to mess with water cooling but might consider it. What are your thoughts on a Peltier cooler (TEC)?

    Ya, all those I suggested above use a Bolt Thru with screws and a backplate so they would all be good for your thoughts about it all.

    TEC is harder to get setup then water, I'd suggest a good air cooler until you have $200-300 to spend on a quality water setup

    Thanks. I need to resolve the temp problem before I continue with the OC. I'll report back later.

    Best regards.

    Good luck in deciding what to get, Be sure to measure your case before you order anything

    I've made improvements to the airflow inside my case which has dropped the temps (both idle and full load) of my case and CPU. I'll also be installing a new CPU cooler which will help.

    I can't seem to get my OC to boot at any FSB at or above 400MHz. I am Prime95 and Memtest86 stable at 3.35GHz (395FSB x 8.5multiplier). My memory settings are as you (Lsdmeasap) suggested in the posts above:

    My system is rock solid at 3.35 GHz with a FSB of 395 but as a soon as I try increasing FSB to 400 or 401 or 402 or 412 or 430 it refuses to POST. I've tried increasing CPU Vcore up a notch at a time (up to 3 increments max). I've tried loosening memory timings to 5-5-5-15 and 5-5-5-18 with no luck. I've tried manually setting memory multiplie to both 2.0 and 2.4 with no success. I've even tried a 'Hail Mary' pass attempt setting FSB to 430 with MCH set to 400 all with no success.

    Any suggestions to what I can do or should not be doing to achieve an OC of 3.4GHz or more (not that 3.35GHz isn't good enough really)? I just can't understand the wall I've hit at FSB of 400MHz.

    Thanks.

    You will have to use 400 MCH latch for 400+ FSB, static tread of 8+, and set twr, twtr, and trfc very high until you get booted thru. Use manually set memory mutli of 2.00 and use 2.1V for now as well

    You are likely going to need to set the termination and PLL manually, as well as increase the vcore. I would think 1.34 or so Termination and 1.5-1.56 Pll should help you

    I would also go ahead and set Driving strength profile to 1066, I find that the next one above the speed you are trying to run the ram works best
