Quick Overclock of E6750

[killersheep34]

Hi all.

After purchasing my Thermalright Ultra Extreme a few weeks ago, last week I decided to push the cpu up. After reading about the 3.2gig brick wall on these CPU's, I whacked the FSB upto 450 and am now sitting at 3.6gig. Experienced some crashes, so upped the vcore to what is now being reported as:

1.312V
3.6ghz (450 FSB)
35 Degrees C both cores

I ran Orthos for 1 hour last week, and Core Temp reported cores of not exceeding 35D C, but had to stop it as I had to use the PC for work. I ran 10 hours on saturday night through a gaming session (i know this doesnt stress the CPU), and intend on running Orthos at some point.

If I run orthos for an hour or so, is it safe to then leave it running for a while longer? Gonna find it difficult to leave ti running for 8 hours and be "local" to the PC over the next few weeks. Also, if it's stable at this speed, do you think there's more of a potential overclock?

I have to say I'm impressed with:
a) The performance of the cooler - it's knocked a whole lot off the standard Intel HSF!
b) The cooling performance of my new case (CM-690). Nothing seems to be generating much or any heat under load. After a 2 hour game of C&C3 on saturday, I touched the heatsink of the GPU and it was stone cold!

Thanks for any advise or help in advance.

1st time read read that. saw a few hit 3.8-4
nice oc, on orthos, would be best bet to try & get it to run longer, find out if it truly stable. most around here would say stable if ran 8 hrs ++. all have different views
your temps seem fine may have more room to go even further

my vcore need 1.4 to be 8hrs stable, temps under full loads 55-60 (warm Room)

I will try and run orthos as soon as I get home from work tomorrow. Just means no playing on steam tomorrow night! Grrr.

I was shocked with temps to be honest. I never knew an aftermarket heatsink could make such a difference. I was running Orthos when all the heating was on too as I remember my partner was home (freeze arse).

I was running my kit in a Lian-Li PC60 (I think it was) but the older version. Had 1 x 120mm intake fan, 1 x 80mm intake fan, and 1 x 80mm exhaust fan. All of my components were running quite toasty, and it was worrying me, the temperature of my hard drives. I work in the IT industry, and a lot of our support calls are for faulty hard drives. This is because the cases used have poor cooling. I also used the standard intel cooler, and I was running at temps of around 55C, and that was at stock speeds! There was no room for overclocking, I did try it, but I got NTFS errors, blue screens, and all sort of issues.

I know I've already bigged it up, but I am so impressed with the value for money regarding the coolermaster case. It has a seriously good cooling system, and the big rubber feet really do dampen out a lot of the sound. Next up are some fan controllers (need to control 8 fans)! Was also thinking about watercooling, but know it would be a squeeze in this case.
