Possible CPU problem or Motherboard?

[ironmysox]

Hi all.

My problem is this, Out of the box stock settings, no overclock, Bios at optimized defaults, I keep getting a BSOD saying this "A clock interrupt was not received on a secondary processor". I have googled as best I can but a lot of replies tell people things such as "It's a compatibility issue" etc. It doesn't always do it straight away, earlier I managed to get in a couple of hours of Dead Space 2 then BSOD. Then it did it just 5 mins after switch on.

I have gone over the machine with a fine tooth comb and got second and third opinions and they all agree it's assembled perfectly.

I have tried things like turning all the power savings off, disabling hyperthreading and anything in bios I dont use etc but it makes no difference. I had a retail i2500K in this machine before and never had a problem (and I have checked no cpu pins were bent in the removal and replacement procedure).

May be a silly question but are OEM chips identical to retail apart from no cooler or retail box?

Hope this makes some kind of sense, I'm tearing my hair out and at 41 with a history of baldness in the family I need to stop!

Thanks in advance

Chris

yeh, did a total reinstall. Used the latests drivers from the Z68X-UD5 download page. All that side of it seems fine. I have never had a problem before with any system I've had, just this one. Bit of a pain but still, it happens. Might have chance to test in a the new MSI Z68 board as a friend had bought one and is yet to open it so that will be interesting.

Yeh, I posted on the gigabyte forum and a tech support sent me a link to the latest bios which I googled before I flashed and found it posted up on tweaktown as the latest beta. Flash went well but still the BSOD at random and always the same message. We have just put my chip in his case with the new MSI board (which is very very nice may I add), with my memory and it's been running prime for 35 mins without a hiccup.

I think the message made me think it was the cpu because of the wording "A clock interrupt was not received on a secondary processor" but maybe that's just a non experienced conclusion jump.

Well it's still running with no problems. Going to leave it for a few hours and then switch back to the gigabyte board with a fresh bare install on a new drive.

Well one day later and the results are kind of odd. My i2600k chip in the MSI works fine and his i2500k chip in my Gigabyte works fine (prime 95 ran for 6 hours). Swap them back (cmos reset of course) and my chip fails in my Giga board (prime 95 lasted 14 mins). Puzzled to say the least but the chip is fine it seems, just doesn't sit right my my mobo. And he won't swap so I might have to bite the bullet and just get the Msi board for my rig.

That's exactly what I'm testing at the mo. Now after swapping this and that, it seems my chip on his MSI mobo with his or my ram is fine (he is using 4GB G.Skill DDR3 PC3-17600 2200MHz RipjawsX Series). Now we are running my chip on my mobo with his memory and so far no probs at all. Nearly three hours of prime and stable so far. With my mem in it lasts less than 45 mins every time. Who said PC's were straight forward?

Still, all a learning curve. If this runs ok for another few hours I will just purchase some GSkill memory (It looks pretty smart as well). Thanks for replies btw
