E8400 stuck @3.375

MSI P6N SLI Platinum
E8400
2x1Gb G-Skill DDR2 800Mhz (D9 Chips)

I have the latest BIOS and drivers, but my E8400 will not go over 375Mhz FSB. I've tried increasing voltage and loosening memory timings, but it will not post at anything higher than 375. Is this becuase of my mobo, or do I have a bad chip?
 
I guess I should mention that I have A Zalman CNPS 7900 with a 120mm fan 6 inches in front of it and another 120mm fan 1 1/2 inches behind it. I like to call it my wind tunnel. I have already checked the seating of the cooler, and I applied the perfect amount of Arctic Silver 5.

The old E6600 could go all the way to 3.3Ghz, and idle @ 22-27c. Wonder why this one won't go higher.
 
I had this problem with my friends E8400 on GA-P35-DS3L with the Cooler Pro 7
He was able it get it to 4ghz when he exchanged the chip for a new one

I have my E8400 on my GA-P35-DS3L at 3.753GHz with stock cooling so when we built his I was surprised


Sorry thats all the help i can give
 
my xeon 3060/e6600 is the same way, and im using the same 2x1GB g.skill ddr2-800 sticks too. i cant go above 360-370fsb either...

i think its your chip...

So, can I tell newegg, "I need a new chip b/c this one won't overclock high enough!"?

Obviously not. BTW, at what speed are you running your RAM? Also, are you aware that you should always reset your BIOS, when changing processors?<<-- That's assuming a process change, like your swap involves.
 
Your RAM should be @ 333/667 DDR, or did you mean 750-800 DDR after the pverclock? If so, you just ended up with a bad overclocking chip, assuming you had the other settings & voltages correct.
 
Try shooting straight for 400 mhz fsb. Maybe you're in an FSB hole. Try it with a lower multiplier first, and if it is happy with a 400 fsb try from there.

Also, the *ethical* thing to do when OCing is to sell hardware which doesn't meet your goal and try the lotto again. RMAing hardware which fails to hit OC targets set by professional OCers costs karma in addition to $, and results in higher prices for all of us down the road. Please don't steal from r/etailers.

Woah! Are you trying to kill that chip? I hope it lasts longer than 45 days lol. There have been degredation reports at 1.5v. Im not sure why a your chip would even need that much for 4.25....

i am sort of in same boat . e8400 with beta bios for a ga-965p-dq6 . i can run it at 380*9 = 3.42 without any adjustments to voltage whatsoever . i tried to get even up to 390*9 and its a no go. i adjusted Vcore from 1.23 to 1.30 and the FSB and MCH (?) up +0.15 , as well as +.10 to the ram. and it wont post into bios . anyone know if i am just being too conservative with voltage increases (and what sort of + i should give to Vcore, fsb, mch , ram) or this may be the limit . i am also running 2x1 of xms2 800, which is why id like to get a 400 fsb for a 1:1 ratio . the only odd thing is i used gigabytes CIA2 on 'turbo' mode and was able to acheive 397*9 = 3.6Ghz by watching cpu-z, but since the voltages are automatically adjusted as needed and not shown in bios i have no clue what the board is setting them at and am a little paranoid to run it there, even thought temperatures on the cpu stayed at 50C under orthos . is there any reason to /not/ use automatic overclocking profiles like CIA2 ? thanks a lot .

He sent it back cause it wasn't doing something that voids the warrenty?
