hey guys....im currently at 4.0ghz using 1.43v and upped vtt by 1.32 ? is it ok ? tends to crash during prime and then restart

means ur settings are unstable.. try increasing the vcore a little..

ok changed now vtt is at 1.32, vcore at 1.46 and temps when running small fft on prime 95 is 81,76,78,80 on all 4 cores....please advised if anything is wrong

woah over 80C... thats hot.. whats the idle temp and wat cooler u using?.. u planning to run that for daily settings?

idling temp is around 50-55, using xigmatek hdt-1283, intending to break it to 500fsb to see if my proc and mobo able to. Running daily would be around 4ghz

I dunno if someone already open this thread before cuz i browse through but never seen E8600 being oc'd.. so let me start first.. i have a Intel Core 2 Duo E8600 3.3Ghz E0 stepping (thanks to NickMan). What i did was pair'd it up with a Asus Maximus II Formula P45 mobo and the magic starts to happen. First of all i tried a 400X10 = 4.0Ghz at stock V.Core and it worked so i tried step by step to reach the max OC speed. Forgot to say. I was using Coolermaster Gemini II with 2 Vizo 1800RPM 12mm fans. So at 4.0Ghz @ 52c non air-cond room was stable without fail. I tried raising the clock speed again by 400~410~420~430. at 430X10 = 4.3Ghz it failed and end up with a blue screen of death. So i started raising the v.core to 1.392V and it load ok. but the tempreature gave me goosebumps. Which was at 76c.. quite high for a processor tempreature. so i took the risk and played with the clock.. For this time i used 440X10 = 4.4Ghz OMG!!!! it reached without fail. but temps were tempting. 76c idol and 92c 100% Load!!! really2 going to have an heart attack. so again i pushed it to 450X10 = 4.5Ghz stable but HOT!!! 85c at normal and 98c at 100% LOAD!!! wuhh... can fry egg!!! i tried to push it higher to 460X10 it managed to change the speed to 4.6Ghz but then restart so i know it was heating cuz i set the max temp at 100c. what was i thinking risking a lot of $$$ just to oc.. but it was a fun experiment cuz its really hard to reach those clock speed with air cooling instead of water cooling.. now what im planning is to find a watercooling set that can support my E8600.. no Thermaltake or Coolermaster toys.. what i have in mind is a Zalman resovator 2 or from Swiftech.. i heard thier pumps are great... ok for my test Bed was using

do you run your stress program with CPU-Z (or other realtime CPU speed reporting tool) in background?
because once the CPU hit tjmax thermal throttle will make CPU multiplier drop to 6x.
btw, nice rig man

before i took this screnshot yes i was.. see the max temp after the 100% load.. i was playing COD4 before i took the pics.. thanks man.. hehehe.. forgot to mention.. i disabled the C1e, Speedstep and 1 more i forgot liaw what i disabled.. so it never underclock.. it just stays at that speed.

Suggestion:Reseat Heatsink and change to better thermal paste,temp might be high because of seat issue

well i hav a e8600. Managed to clock at 450x10 4.5ghz 1800 fsb air cooling with no fail. I posted it but now closed. Waiting 4 mod to put it here. The testbed was.
Intel core 2 duo E8600
Asus Maximus 2 formula
Coolermaster gemini 2.
I tried 4.6ghz but pc restart. Think temp reachd 100c cuz i set it at that point to restart. But it did run 4 a while cuz playing cod4 just after the oc.

Try to reseat HS and change TIM

how is your NB temp when you reach 4.5ghz.
had you do the washer mod for NB yet?

pcprobe screenshot plzzz

My nb was at 5+. The cputt something was very2 hot. At 84. Anyway. That time when i oc. I just realize that my hsf was not straight and a small gap. Mayb thats the prob of the temp. Well. Its just my luck reaching 4.5. Well now im at 4.75 with fan. Temp reaching 82c with a help of 2 table fan. Ill post some screenshots 2 aftewards when im free 2 go to cc. Just wait.

Try reseat your heatsink,might be due to bad seat

Can help me to decide between a x48 rampage formula or keep my p45 asus maximus 2? Which is worth it? Help2!

Are you sure this is with a phase
I think 5.3ghz+ is more along the line of what you should get
Heck i even did 4.8ghz with C0 E8400 on water
