Problems with Q8300

[mcfrostyjim]

Hey guys,

I recently purchased a intel core 2 quad q8300 to replace my old intel core 2 duo e7300 but I've
been having problems. When the q8300 is in the socket and I boot, I get past POST fine however once it hits the windows logo, it flashes, freezes for a second and either enters into a black screen or BSOD (usually some irql_not_less_or_equal, not always the same error). Sometimes if I'm lucky I can boot with single core enabled, and only once did I get into desktop with all 4 cores enabled. BIOS is updated to the latest version for my motherboard which is a intel DG35EC. The computer boots and runs just fine on my old e7300. In BIOS the q8300 also comes up as intel genuine but doesn't actually state the model as the dual core does. I tried running intel's processor test which the q8300 passes on. Could I have a dud or am I missing something here? Any help would be greatly appreciated.

Thank you.

What your psu? make and model

My PSU is a EVGA supernova NEX650G.

Sounds like windows is not recognizing your CPU properly
I would suggest trying this: disable VT-x ,Speedstep ,Idle states , Execute Disable bit in the BIOS, this should allow you to boot then run sysprep on your Windows installation. When Windows restarts it should re-detect all system devices including your new CPU. You can find Sysprep from support.microsoft.com just make sure you download the correct version for your windows.

Thanks for the replies. In BIOS the dual core shows VT however with the q8300 that option isn't even there. Another issue is the computer hangs when exiting BIOS with the q8300 and requires a manual reboot (actually 2, 1 to exit and once more because the monitor blinks but doesn't turn on). With the dual core its able to save and exit BIOS and restart on its own.

Also should I be freshly installing windows again once I change the cpu?

Is the 2x2 cpu power on the motherboard is plug in from the psu?

 

[mcfrostyjim]

Yes, everything is plugged in.

 

[rgd1101]

just want to make sure which version of bios?

Sometimes if I'm lucky I can boot with single core enabled, and only once did I get into desktop with all 4 cores enabled.

you doing that in bios?

BIOS Update [ECG3510M.86A]
This download record provides three options for updating the BIOS of the Intel® Desktop Board DG35EC.

(Latest) BIOS

And yes the option to run in single core mode is in the BIOS.

I've also been reading that manufacturer refurbished CPU's could have their cache damaged by previous owner, could that have anything to do with this?

I bought the cpu on newegg and intel cpu test checks out ok.

 

[rgd1101]

what kind of intel cpu test? performance load test or just IDing? It do sound like is damaged. Checked the pin on it?

 

[mcfrostyjim]

The intel processor diagnostic tool. No visible damage on the pins. The cpu boots up to windows loading icon then crashes to a BSOD. I also forgot to mention I after I did a fresh install of windows with the quad core it loaded and I used setfsb to check the fsb settings, raised it by 10 and thats when the problem began. I uninstalled it (It was the .zip version of setfsb) and I cleared BIOS by removing the CMOS battery. I also tried to look in regedit like a guide to fully uninstall setfsb said however it was not there. I'm backing up my data so I can reformat and reinstall windows with the quad core installed. Will let you know if that fixes it.

Trying to reinstall windows with the quad core fails. It shows the windows logo then proceeds to a black screen with the monitor blinking, fans and power are still on however monitor seems to be getting no signal when this happens, should I reinstall with the core 2 duo and switch it to the quad after?

edit: I'm finally able to enter windows installer but only with SW Single Core Mode set to enabled. Formatted and reinstalling windows now, on the qiad core

latest: quad core is working when the bios option sw single core mode is enabled but as soon as I change it to disabled I get 1 of 3 BSOD upon booting into windows (0x0000000A, 0x0000001E and 0x000000D1). This is after freshly installing windows again.

At this point, I believe one of the cores are faulty. Will throw the q8300 out and buy a new one. Thanks for all the help thus far.

 

[rgd1101]

I remember reading somewhere on the board once you got setfsb bsod , even a reinstall os doesn't work. how long did you leave the cmos battery out?

 

[mcfrostyjim]

About an hour with CMOS battery out and power unplugged.
