I need a quick answer if possible.

Recommended Posts

Greetings, I just removed a E6550 Dual Core Conroe CPU from my P5N-E-SLI motherboard. I installed a new Q6600 Quad Core ( Kentsfield ). All boot up, Windows VISTA operations ran great. I installed the stock fan. My 4 core temps are running 47,47,46,42. Is this a safe operating range? The fan is installed correctly with Arctic Silver.The frequency stated on CORE TEMP says 2400.00 (Mhz)( 266.67 X 9.0 )VID 1.2875vRevision: GOAnyone see any problems?TurnipSPECS:VISTA Home Basic 580 WATT Sunbeam PowerCrucial Ballistix 4GB(2 x 2GB) 240-Pin DDR2 SDRAMASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard Intel Core 2 Quad Q6600 Kentsfiled 2.4GHz LGA 775 65W Quad-Core Processor Model BX80562Q6600ATI Radeon 3870 512250 GB WD SATA HD 120 GB WD IDE HDftxsupporter.gif[/url]

You're doing great! Which utility are you using to monitor the temps? Just be careful if the temperatures go into the 80s and 90s especially.Congrats on the transition from 2 to 4 cores! :-beerchug Regards,

Thx a ton for the quick response BG. Your input is always most welcome. I'm using Core Temp 0.97.1 to monitor the temps. It also shows up all 4 cores on the task bar.TurnipSPECS:TurnipSPECS:VISTA Home Basic 580 WATT Sunbeam PowerCrucial Ballistix 4GB(2 x 2GB) 240-Pin DDR2 SDRAMASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard Intel Core 2 Quad Q6600 Kentsfiled 2.4GHz LGA 775 65W Quad-Core Processor Model BX80562Q6600ATI Radeon 3870 512250 GB WD SATA HD 120 GB WD IDE HDftxsupporter.gif[/url]

Overclocking scares the #### out of me. I did a lot of reading on it but all I got was confused. The RAM timings and all that clock speed stuff is over my head. I haven't found anyone with a system like mine that could walk me thru it.VISTA580W Dual Rail PowerCrucial Ballistix 4GB DDR2ASUS P5N-E SLI MBIntel Quad Core Q6600 Kentsfield 2.4ATI Radeon 3870 512 250 GB WD SATA HD

Not that big of a deal to o/c really. Far better minds than mine have commented that for FSX, memory timing tweaks are relatively unimportant so disregard that are and focus on clock speed.The simplest form of o/c on your system would be to increase the cpu clock to 375 from 266 - this would give you (375x9) 3.375. With the stock cooler you should be ok but after you make the change and reboot, start monitoring the temps at idle. Then pick one of the many o/c testing programs like Prime95 and run that for a few hours watching the temps. The Q6600 will throttle down if it gets too hot so you're not risking anything. Now, this would be a simple mild overclock and should work with no issues.Since you say you've read up on it I won't go into details but get into your BIOS and look for the area where you can change the system clock speed. You will have an option to use linked or unlinked - I use the linked mode which also bumps up the memory as I understand it.Do not change the multiplier - just change the box with the 266 in it to 375 and save and reboot. Don't mess with anything else, no voltage changes, etc.If it rebooots and the temps are fine and you can run Prime95 for several hours, preferably overnight, without errors -you're home free.FWIW, many people have gotten the Q6600p to 4GHZ stable with liquid cooling. I got it there but it wasn't stable and I really didn't have the time to get into higher level tweaking so I settled for 3.6 o/c.If you stay away from voltage changes you should be fine. If it doesn't boot, reset the BIOS and try again, no big deal.Good luck,VicQ6600 G0 CPU 2.4 o/c 3.65Evga 680i A1 with P31 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx XG 174.74 702/1620/792Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/banners/hifi-supporter-sigbanner.jpg

I'm running that Q6600 at 3.6 without any issues. You will need this cooler (+ a 120mm fan) for anything above ~ 3.0.http://www.directron.com/u120e.htmlGet a trial copy of Everest. Watch your temps and voltages with their system stability real time chart. Once you have your cooling, set your CPU volts to 1.45 and your FSB to 400. That will give you a 9x400=3.6Ghz CPU speed. Temps will be in the hi 70s. That's fine. Leave all other settings in auto.The P35 moboss will just go there. The Nvidia mobo chipsets can have a real 'tude with a quad. Make sure your ram is rated to run at 800mhz (DDR2-800). That's it. Boot n run. Go fly.

vgbaron, If I wanted to bring it up to, lets say 3.0 instead of 3.375, what entry would I make in the BIOS? I'm thinking that I may start out a little lower then build into a higher setting. Your thoughts?

I have a question for you... Might be a little dumb but here goes..At the moment I have this big fan on my cpu, where does this cooling sink go and how does it work ? Does it fit on top of the fan ??Steve

Thanks a bunch for that link, that explains everything.I have an overclocked E6600 now but plan on upgrading to a E8600 soon and overclocking it as well.Steve

Your thoughts?Always move at the speed that YOU are comfortable with - go with 3 for a while and see what develops. If all OK, and it should be, kick it up a notch.Simplest way to calculate - your multiplier in the q6600 is 9 so 3.0/9= 333 - that's your setting. I have mine set at 405 so 405x9=3645For what you want, do not mess around with changing the multiplier.Have fun,VicQ6600 G0 CPU 2.4 o/c 3.65Evga 680i A1 with P31 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx XG 174.74 702/1620/792Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/banners/hifi-supporter-sigbanner.jpg

Droop is good. Droop on. The idea is that voltage will not remain precisely stable during an unload event. It will increase, then return to its regulated level. That overshoot on the high side might momentarily exceed a Vmax level. The voltage reduction that occurs under load (Vdroop) will allow this voltage recovery event without overshooting Vmax. Droop is a design parameter, not a sign of a weak mobo.
