MastrSplyntr Posted February 27, 2013 Posted February 27, 2013 System Specs Processor - Q6600 2.4 Ghz Motherboard - ASUS P5KC (BIOS version 1203) RAM - 4GB DDR3 (x1) Graphic Card - Sapphire 6770 1GB GDDR5 HDD - WD Caviar Green 1TB PSU - Cooler Master 460 W As you can see my processor is quite old and runs at 1066 FSB (stock) so I tried OCing it to 1333 Mhz FSB that is 3.0 Ghz basically to get the most out of my RAM (1333 MHz w/o OC) but even at 2.7 Ghz (300x9) my idle temperature is around 55 to 60 while prime 95 pushes it to as high as 81. Intel recommends a max temperature of 71 for my processor. At 3.0 Ghz my system gets really unstable, prime95 would give errors plus taking the temp as high as 91 degree before I killed the power out of fright I tried googling the combo of P5KC + Q6600 Overclock and have seen SO MANY people (enviously >_<) easily overclock it to 3.4 to 3.6 Ghz without any substantial change in temp (less than 60 sometimes even 40 when Idle) which is even less than my idle temperature at 2.7 GHz !!! I live in Karachi and my room temperature these days is in b/w 25 and 30 degree. Plus my casing has two additional fans OTHER than those on CPU, GPU and PSU, inshort its quite ventilated. Im quite sure the problem is in my BIOS settings, most of which I set to Auto as I have no idea what they mean D: Its the first time I tried OCing CPU. << IN SHORT, MY PROBLEM IS WITH THE ABNORMAL CORE TEMPERATURES PLUS I WOULD LIKE TO KEEP MY CPU CLOCKED (STABLE) AT 3.0 GHz AT 1333 FSB >> Following are my current BIOS settings: AI overclock Tuner set to MANUAL CPU Ratio Setting - AUTO FSB Strap to North Bridge - AUTO FSB Frequency - 300 PCIE Frequency - AUTO DRAM Frequency - 1202 DRAM Command Rate - 1N DRAM Timing Control - AUTO DRAM Static Read Control - AUTO DRAM Dynamic Write Control - AUTO Adjust CHA SKEW Support - AUTO Adjust CHB SKEW Support - AUTO Transaction Booster - AUTO CPU Voltage - AUTO CPU PLL Voltage - AUTO FSB Termination Voltage - AUTO DRAM Voltage - AUTO NB Voltage - AUTO Clock Over-charging Voltage - AUTO Load-line Calibration - AUTO CPU GTL Voltage Reference - AUTO NB GTL Voltage Reference - AUTO CPU Spread Spectrum - AUTO PCIE Spread Spectrum - AUTO I did try lowering the CPU Voltage but then either the system gives BSOD or hangs at too low voltage OR there is no difference in temperature. Please let me know what settings to use ABOVE to lower my system temperature. And do I need changing anything for the RAM, I guess NOT :S Im pretty sure leaving most of it to AUTO is the problem. Oh and I use CPU-Z to check the clocks frequency etc and Core Temp for temperature plus my Graphic Card is at less than 40 when idle so it doesnt contribute a lot of heat in the casing.

wevsspot Posted February 27, 2013 Posted February 27, 2013 Mastr - welcome to our community here at the OCC forums. What kind of CPU cooling are you using? I suspect that is the culprit in your instability and your heat issues. The Q6600 is an oldie but a goodie - and while I'm sure there is some overclocking headroom left in it, and I'm sure that you'll need to manually set your vcore - you won't be able to get the clocks you're looking for by under-volting.

Lawl thank you moderator Well yeah, Im using the stockcooler for now but AFAICS my CPU should run fine upto 3.0 Ghz atleast on the stockcooler. Is it right ? Secondly I tried adjusting the vcore manually and the system kept on crashing until it was set to 1.3125 volts, so I just added 0.0125 more as per my processors VID 3.1250v. I know yeah, its been almost 5 years since I bought this processor and I havent had any performance issues so far. For gaming, my graphics card seems to be the bottleneck otherwise its just the HDD for which im thinking of upgrading to SSD. Oh and lastly, in all those BIOS settings of mine, what would you suggest I change ?? as I have no idea what most of it means :S Edited March 1, 2013 by MastrSplyntr Share this post Link to post Share on other sites More sharing options...
cjloki Posted March 1, 2013 Posted March 1, 2013 yes, welcome MastrSplyntr out of curiosity what is your native ddr3 ram speed ?...and yes what wevsspot said, cooling matters !...aside from that, if you are pushing the ram beyond it's native settings (which it looks like might be the case) then you get much instability... yes i did run a q6600 on a p5kc with both ddr2 @1066 and later with ddr3@1333 ...q6600's (with proper cooling) have been known to hold fast and strong at 3.4ghz and even higher, so it's just a matter of dialing it in once it can handle the heat...

Alright now I would ask, is there anyway to increase(overclock) CPU FSB ONLY but keeping its speed constant at 2.4 Ghz ?? My room temp is less than 25 these days (KHI) and its been hardly two weeks since I used a blower to clear all the sand, dust particles in the casing which has 3 fans other than those on CPU, GPU and PSU ! AND at 2.4 Ghz (stockclock) CPU idle temp is 56 while prime95 pushes it upto 85 before I halt the process. all in all, this is NOT normal right ?

Locutus Posted March 1, 2013 Posted March 1, 2013 You can increase the FSB and decrease the multiplier. Share this post Link to post Share on other sites More sharing options...
Hyper Posted March 1, 2013 Posted March 1, 2013 The problem is with the stock cooler and the auto settings on the voltages. In several cases the auto settings will actually over volt more then is needed for the OC, ramping the heat higher then it could be if you manually set the voltages.. and as someone else mentionged you can always up the buss to the 1333 target for the ram and drop the multiplier down a notch which might help but your over all oc would be less... on a side note I had a duo core of that gen that would over heat at stock settings during the summer with the stock cooler if the room got over 30C... changed the cooler and that problem went away and was able to have an oc during the summer. I also remember somthing about the north bridge voltage needing to be tweeked but you will need to watch the chipsent temps as well Share this post Link to post Share on other sites More sharing options...

cjloki Posted March 1, 2013 Posted March 1, 2013 most everything you need to know to overclock the hell outta that q6600 can be found in verran's guide to overclocking right here (a must read) and more specifically in this guide by graysky but like we're saying, it doesn't mean dooddlysquat with out a decent heatsink/fan setup...it won't work without it...

MastrSplyntr Posted March 2, 2013 Posted March 2, 2013 lawl, decreasing the multiplier and increasing FSB works like a charm. Thanks a lot for that. How come I never thought of it :X @Hyper: thanks for the info. for now at 333x8 it seems stable with temps higher by only 3 degrees compared to default clock. even though i didnt understand the northbridge thing, should i attempt it w/o an aftermarket cooler ? as it seems to be the mobo temp diff from that of cpu ?@wardozerx: mine is revision G0 according to CPU-Z and its been almost 4-5 years since I bought it. I doubt that will be available here in karachi, i checked thru a couple of online stores and the cheapest is priced at 30$ i.e THERMALTAKE CONTAC 29 which I dont think is worth it ? Hyper 212 Evo seems better at a bit higher price 42$.Anyway thanks everyone Share this post Link to post Share on other sites More sharing options...

Hyper Posted March 3, 2013 Posted March 3, 2013 Typically what I did to help keep the chipset on them boards a little cooler is get a small fan and make a bracket to point it at the chipset to help air flow over the hot spots. just make sure your not configuring it to push against other fans, just help direct it to where you want extra air flow . as far as cpu (mine was a B0 stepping..) if your temps are in control go with it.. but it may limit hitting max oc potential, if thats what your going for..
