who have e6750 post here....

Haven't even tried to push mine yet, but it's running nice and cool with stock cooling at 3.2ghz

Been too busy working out build issues to do any but the most basic OC yet. Was impressed at how little it heated up going from stock to 3.2 though :)
 
Running mine at 3.2.. I cant get 3.6 stable although I had it stable in orthos for about 10min. It doesnt seem to have any issue in windows even tho Orthos says different. I had to take the voltage up pretty high 1.5-1.55 to get it at 3.6 and it could be my laod temps of 51C that are causing me issues... who knows. Wish I had spent a little more for a quadcore.
 
I haven't messed with it much beyond this.

What cooling are you using? On my E6850, I'm experimenting with 3.9ghz and it's stable so far. I have a thermalright ultra extreme 120+. When I run orthos my temp never goes above 52C, thats with a lapped CPU/HS so thats pretty good. I have a push/pull arangement in an open side case. I think the 680i might be holding you back. I'm really believeing thats tho only thing thats stopping me from hitting 4.0+, my shitty fsb is holding me back. My ram is is still running at 4-3-3-3 with no issues. Crank the volts on your mobo, that should fix your ceiling issue. Plus, you might want to search the xtremesystems.org forums for the vdroop penicl mod for the 680i ;-)
 
what should I expect to overclock my 6750 to. I'm only using the Intel Heatsink fan. I got it to 3.0ghz, but haven't gone any higher.
 
I run my E6750 everyday at 3.6GHz, it's very stable. It required 1.4875 volts, but still seems to run rather cool with my Tuniq Tower, Orthos small FFTs only get up to 50c.

I think the CPU is capable of quite a bit more, unfortunately my testing seems to indicate my motherboard is holding it back. I can't do 460MHz or greater FSB.

So I'm waiting for the X38 boards.

Still, quite happy with my 3.6GHz.
 
Currently keeping mine at 3.2ghz using 1.352v no real need to go much higher. Now my video card... that I pushed as high as I could go.

put it at 1.58V (1.56 in windows) and im running 3.64ghz orthos stable for an hour with no problems. Idle temps in the high 30s and max load temp was 63C. Guess my chip just likes a little more voltage. I wouldnt recommend this much voltage unless a good heatsink is used.
 
I'm at 3.4Ghz w/ 1.36v. 9hours stable with Prime95, i couldnt be arsed running it more. Also the temps hit 47c after the said 9hours.
I could probs go higher.

What are you using to check youre temps? 47C after 9 hours of Prime is really good. Ive built about 5 core 2 duo systems recently and they all get into the 50s or 60s after hours of prime with a better heatsink then your running. Make sure your using coretemp to verify temps and make sure its the 100C tjunction or it will read 15C to low. Dont depend on your motherboards software as it probably isnt accurate. My motherboard says im at 43C under load and core temp wtih an 85C tjuction says im at 48C which is incorrect.
 
I use TAT. I get ~~52c with the 100% workload. The readings in Coretemp were the same after 9hours of prime95 (~~47c)

My sceenie with the temps open too got deleted, so I'll get one when I get home..i think the CPU is at 38c.
 
I run my e6750 day and night at 3.4 GHZ 1.38v atm , no need to run it higher. I have gotten it stable at 3.8 but that was just for testing purposes.

Same here. Running at 3.4Ghz at 1.375 volts. Approx 56-57 degrees under load with ORTHOS.
 
plz give us ur temps reported by CORE TEMP v0.95.4 (not v0.95, the diff is the tjunction is 100 when u use 0.95.4. the diff in temp is about 10~15 degree)

im currently running mine @ 3.4 GHz and CORE TEMP 0.95.4 reports around 42~45 idle and 61~63 when running orthos stress tests for 7+ hours.

and my cooling is arctic cooling freezer 7 pro.

3.4 GHZ

Core Temp 0.95.4

Idle: 31C-33C


Load: 57-58C

I just got mine a couple days ago so I have not pushed it a lot yet.

Running 3.3 with Arctic Cooling Freezer 7 Pro for cooling. Voltage is at 1.256 and it is completely stable. I may even be able to undervolt.

I did not bother putting on my AS5 and used the HSF's grease. Temps are 33 idle for each core. Load is 47.

I've gotten mine up to 3.55Ghz on the stock cooler. For day to day operation, I've been running at a whopping 2.0Ghz. The difference honestly isn't all that noticeable even with tons of programs running, and for things that need it, I just reboot and bring it up to 3.4 or so. No need to get it hotter and louder for most things though, you know?

One of these days I'll actually get a decent cooler. I've just not gotten around to it yet.
 
in present,i use my cpu at 3,6ghz daily use (1,45v),wheater its cold hier,temperatures is below 4-5 grades celsius,indoor is maximum 22-23.its perfect for use at higher clocks.

its to little voltage for this cpu
in the future you have maybe ,you have problems in aplication,like games,encoding and other stuff hungry of power.
Be careful at blue screen.
good luck

That picture shows the wrong tjunction for an E6750... add 15C to that temp to compare it to an E6600 with an Tjucntcion of 85. If everyone wants to compare temps lets use the latest version of CoreTemp that uses the 100 Tjunction for this chip.
 
last core temp is same tjuction at 85 grades.
show me 100 grade s tjunction at 6750...
 
I only OC for games, and then I run mine at 3.6 GHz (450 FSB) on stock voltages, which cpuz says is 1.35V. I have taken it as high as 3.8 GHz but couldn't get it stable at those speeds (although I didn't try very hard). It idles at 35C and Orthos takes it up to ~58-60C.
 
Just got my e6750 stable last night at 3.5ghz (ran 16 hours in orthos). Used 1.5vcore then now running it with 1.44vcore. (everest reads 1.4Vcore with orthos running)

:D very happy with the way this chip performs compared to my brisbane @ 2.85ghz. Vista loads in a heartbeat.

memory is currently at 4-4-4-8 2.3v 1:1 (ddr2- 876)

would it be faster for me to run it at 5-5-5-15, for example, at a 1:1.2 ratio? (ddr2-1050)

as of right now I'm a lil over an hour into orthos and just opened my window (its about 50 degrees F outside) and everest is recording the core temps at 43C. :cool:

normally it doesn't get over 60C though...I'm so glad I made the switch!

What are you running your other voltages at? NB etc.....
 
9 hours stable in Orthos @ 438x8 / 3504Mhz - temps are at 65C in CoreTemp. Going to try to back down the voltage down as much as I can but try to keep it at 3.5Ghz. What is a reasonable daily operating temp? Memory is at 5-5-5-15 / 438, 2.3v.

With the new S-flex fan I added im getting in the high 30s at idle and it now peaks at 59C in Orthos. This is with 1.58V. I am thinking of backing it down but it runs great like this. I am at 8x455... I cant get past this but imt starting to think I need more NB voltage. I havent brought it up past stock voltage yet.
 
I'd like to know if any of you have had to adjust any other options in the bios like NB voltage to keep your cpu's stable. I have mine at 3080mhz, but I'm unsure of what other voltages I need to be aware of to keep it stable. I'm gonna try for 3.2 this weekend so any advice would be nice. I'm on an MSI P35 btw.
 
You can probably hit 3.2 on all stock voltages. If it seems unstable.. take the cpu voltage to 1.4V and test it in Orthos... Start taking the voltage down a little bit at a time and test for stability. Run your voltage as low as you can get stable to help with heat. I think you will find between 1.35 - 1.4 V you will find stabililty easily for 3.2ghz. Here again every chip is different. Good luck. You probably wont have to adjust the NB voltage when trying to run 8X400.
 
I like to push my chips as far as possible on stock volts and stock cooling before I proceed...

At the moment, I am at 3.5ghz on stock cooling/volts and I seem to be hitting a wall. Mind you, I keep my memory at a 1:1 ratio so I still need to see if it is my memory or the CPU holding me back.

I may get a better cooler or I may just stick with 3.5ghz which is plenty :D

No matter how good your cooling is.. 3.5ghz on STOCK voltage is already a real real good OC.
