Nice chip m8! good job!

my e6750 (system i sign) is at 3,4Ghz atm, 1,475V bios, 1,456V CPU-z. This is stable in orthos for 14h. 433x8 failed after 2h with 1,5V bios. Guess its dont worth the xtra voltage it takes to go higher, at least in 24/7.

And my memory was a bad suprise, everbody seemed to reach atleast 900 and often 1000 with those, my are with nanya B chips, 880 Max, cl 4 = no boot, higher volts makes it unstable and above 2,1 = no boot.

Any suggestions that might improve my OC?

And btw, first post, but I´ve been reading this forum for years! It is really exciting, fun and intresting.

weekend tests with my friend nepo:


E6750 + P35C-DS3R + GSKILL DDR2 PC6400 HZ AIR COOLED BY TUNIQ

I can take 500*8 :( even 1.55 vcore :( i suspect the timmings os the mems or other little settings.

BTW it's a nice results and temps. this G0 revision it's great !!!

cumps

My new speed and specs, problem was the northbridge got too hot:mad: , even to touch for 1 sec .... maybe coz of the high fsb on these things ... i do have extra fan blowing on it but i guess thats not enough and i can't fit aftermarket chipset heatsink coz of the tr ultra ... does anyone else have this prob? well heres my speed with the lowest voltage i could get it stable without orthos failing in the first hour .... will test orthos until 12hr+ small and blend stable.

OK I may have a golden E6750 chip here. FPO: L724A095.

So far testing stock volts overclock range, stock cpu 1.35v BIOS which gives 1.33v idle and 1.31v load. Mobo volts are untouched only vdimm raised to +0.2v. Running it as an open bench environment and it's raining outside so that's why temps are so low with Tuniq Tower 120 at only ~1570rpm.

Will try 3.4GHz next. :p: Can't believe this, I've only had AMD setups before and I always had bad luck getting retail parts but now the first time I try Intel I immediatly have this luck! Maybe it's a sign. :D Doesn't matter, Intel has stolen my whole heart now. Now it has run 1½hrs when I manually stop the Orthos session at 3.36GHz 1.312v.

Not as good as I thought it would be, scales really bad with voltages it seems. Anyways here's what I go for as 24/7 config.

Here is mine setup:

E6750 (G0 Stepping, FPO: L719A782), GB P35 DS4, 2GB Crucial Ballistix PC5300

Validation

For some reason my SPi score is bad for this frequency, any advice?

And yes, believe it or not, this score is with stock HSF :D

1333 strap

Unfortunately, I just tried mine at 425x8 (3.4) on an IP35 Pro and Orthos failed after 30 minutes. I'm gonna drop the multi to 6 and see if my RAM is stable at 450. I'd like to know if it's the processor or the RAM that is sucking :(

EDIT: This *is* at stock voltages, so it's not like I have completely hit a wall here, but I was just seeing what I could do at stock

Just was playing with the CPU for 2 hours :ROTF: .

E6750@3640 (455x8) +0.125V from stock
Ballistix@910 (8-3-3-3-2T)

I think the mobo is locking my cpu, i try to change this mobo for a new p35 or x38...

Hi guys
This's my 1st post on this forum so...hi everybody :)

Some results of mine E6750 boxed, setup on sign.

Everthing done with a thermalright ultra 120 extreme and a Noctua nc-u6 for the chipset cooling.

3,6Ghz@1,42V Orthos stable

http://img178.imageshack.us/img178/7...8142rz1.th.jpg

490 fsb stable (after have passed double 32M Spi)

http://img356.imageshack.us/img356/7...bilihe8.th.jpg

Same thing but 500 fsb stable

http://img356.imageshack.us/img356/8...biliaw4.th.jpg

Double 32M SPi@4 Ghz

http://img341.imageshack.us/img341/9...biliks5.th.jpg

Max fsb seems to be at 515Mhz but this result was obteined with the old cooling system (Scythe Infinity and stock chipset block). With the new one I hope to take more Mhz :)

I am sorry to say I am only clocking my e6750 at 3.2Ghz but here are my temperature reading, Mobo GA P35C DS3R.

I left my PC runninh all day while I was at work, then used Speedfan to take a reading.

Mobo 30C
CPU 1,2 30C

Then rebooted and took a bios reading

Mobo 30C
CPU 1,2 39C

So I added 9C to the SpeedFan readings.

Any body have any similar readings?

Haven't posted in this thread for a while now.

Found some time to some testing for lowest stable Vcore since doing the pencil Vdroop, this early E6750 can actually run 3.6GHz at around VID (VID 1.35v, BIOS Vcore set at 1.375v) which isn't too bad at all.

PS: Somehow, OCCT identifies the E6750 as a Merom in Vista x64. lol

OK, passed 3h of P95 = enough for today. ZZZzzzz...
