As said in title, i ran prime95 in blend and it reached 61'C. I couldnt afford anything to happen cause i have no experience... :( First, around 58'C i heard some loud beeps from computer like POST but lower tone. Then when it reached 61'C ish there was another beep. Everything was 3.2ghz. No settings were changed aside from the frenquency. 400mhz * 8 = 3200mhz. Any problems? Can I go any higher? STOCK FANS in use. :)

well tat seems about right. after all u r using stock cooling. i got a e6750 oced to 3.2 and it goes up to around 55ish using prime95, i dont have stock cooling. im not a overclocking guru but id never want my cpu to get over 65f, id say ur ok, but get come aftermarket cooler. dont know why their is a beeping noise.

I had some information i havent said... 61'C was only part way through the test. I stopped at 61'C but never went on cause i was hesitating.

nvidia gpu's get up to 80 C when playing a game, friend of mine runs his over 70 C sometimes...the e6750 has mechanisms to protect from damage...if it is not crapping out, you are fine.


mine is at 3.6 and been that way for almost 2 years. i have a Scythe Ninja cooler, temp hits 61 C.

thinking about pushing for more.

Hey guys, I am just wondering if anyone comes onto this post and happens to have an e6750 running @ 3.2GHz, if they could post their voltages and whatnot that they were able to get it running stable at. I have aftermarket cooling and really good ram so I know that hardware is not the issue, but settings.

I can get my e6750 up to 3.0 Ghz, and run my RAM at 750Mhz for a 1:1 ratio, but ideally, since I have RAM that is going to be great for a few years (1066 G.Skill), I would like to run my system at 3.2GHz with my RAM at 800Mhz for a 1:1 ratio and a better increase in overall performance.

The problem is that no matter what I do I cannot get 3.2 stable. I have tried upping and downing voltages, and the longest I got it to last at that FSB rate was 30 minutes, but it did not fail due to CPU heat, so I am wondering if I need to up my NB/SB voltages.

I got it stable for thirty minutes @:

3.2 Ghz (400*8) @ 1.29/1.312 Vcore Voltage
RAM @ 800 Mhz, tried both 4-4-4-12 and 4-3-3-10 @ 1.8-1.9v (can run it stable at this voltage @ 750MHz w/ 4-3-3-10 timings, upped it to 2.0v for 800 MHz since I increased the clock and kept the tighter timings).
NB voltage set to 1.35-1.4(1.25 stock)
SB stock voltage (1.5 stock)


I ran a 20 minute Orthos Small FFT test, it was fine and temps peaked at 58 C, but after about ten to fifteen minutes of Wow once I finished the test, I had a total system lockup and had to reset CMOS.

At that point I put everything back to stable @:

3.0 GHz (375*8) @ stock vcore of 1.24, stable @ 57 C full load.
RAM @ 750 MHz (4-3-3-10-23-2t @ 1.9v)
NB stock voltage
SB stock voltage

I will keep this setup for now, just need to know what other people with similar setups are setting their voltages to for NB/SB and CPU Vcore so I can get an idea of what I need to adjust.

Your problem is your timings on ram are way too low. usually 1066 ram is 5-5-5-15 at 2.1. i would loosen up the timings. keep in mind gains from ram settings are minimal.
Loosen up the timings on the ram.
Your voltage on the cpu is too low also. I run mine at 1.40 for 3.6 GHZ
Raise the cpu voltage....
now do your stress test.

1 to 1 is not important in the grand scheme of things.
also some motherboards are not happy doing 400 mhz bus in 1:1 ratio.

Careful with that advice.
GPU's are known to operate temperatures over 100c if needed, CPU's are not.


the max temperature before likely-failure E6750 as Computronix clearly pointed out is 72c. This is very hot and it is NOT recommended by anyone to run under this temperature.
Anything past 65c as the post by Computronix has said is dangerously hot.

I would recommend purchasing some thermal compound like Tuniq TX-2, or Arctic Silver 5 (TX 2 performs the same as arctic silver 5 but does not require a 200 hr curing time like Arctic Silver 5.)
Those two compounds should knock off a good 2c-5c, if you can research some coolers that are compatible with your motherboard, and case.

If Intel asks, your using the original thermal pad.
