GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

[JinxterX]

Hi, I've got a Revision 1.0 GA-EP35-DS3L board and it works fine with E4300 and E6300 Core2Duos but when I stick in a Pentium Dual Core E5200 (SLB9T Malay, 45nm), the board POSTs no problem, however ALL Operating Systems fail to load (i.e. get to the Desktop) with either a reboot or a BSOD stating a Machine Check Exception error.

That's WinXP, Windows 7 and Linux all failing to load properly. The Linux kernel spits out errors about MCE corruption or something.

I've tried BIOS F6 and beta F7a, same problem. Weird thing is I can go into the BIOS, overclock, change settings, anything.. all that stuff works.. just can't get into any Operating Systems, lol, even on default, safe settings.

Any ideas? Is the Rev 1.0 board no good for 45nm? or is this a BIOS issue? CPU faulty?

Never seen this particular problem before, lol. Frustrating.

Is the E5200 known to work on another motherboard? Could be defective CPU.
Try to clear CMOS for a couple of hours with both battery out and shorting CLR_CMOS pins, then load optimized defaults.

The only other board I have to test is a GA-P965-DS3 Rev 1.0, the E5200 does the same thing in that, POSTs but crashes on loading OS. Cleared the CMOS with battery removal (but not for hours just about 30 minutes) and no change.

Would a faulty CPU exhibit these kind of symptoms? Maybe I need a P45 board?

Are you doing clean os installs when e5200 installed? Or put in os disk and doing start up repair? Could the os be lacking a cpu driver?

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

CPU support list of the GA-EP35-DS3L show it's compatible with BIOS F6 and above.
Perhaps try mcelog to get more details about this.

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

The OSes are already installed, I'm just swapping out the CPU.

mcelog looks like the best option to figure this out in Linux, thanks for the link.

Damn shame, this chip overclocks to 4Ghz easily, aargh

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

I wouldn't be so sure of it, not all can handle even 320MHz FSB which is needed for 4GHz.

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

Sounds like a faulty CPU to me, are you sure it's good? You say it can do 4Ghz, have you done that with it, or did you just purchase this CPU from someone else that said it could do 4Ghz?

If you just bought it, then it may have been sold to you faulty, as mentioned above F6 and onwards support that CPU.
GIGABYTE TECHNOLOGY Socket 775 - Intel P35 - GA-EP35-DS3L (rev. 1.x)

So if a extended clearing CMOS and then loading optimized defaults and rebooting does not help the CPU might be faulty

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

I don't know if the CPU is faulty, it came from Ebay (supposedly pulled from a working system) but it POSTs and boots at 4GHz (12 x 333 in BIOS) and crashes loading the OS in exactly the same manner when set to default 2.5GHz (12.5 x 200) so I don't know what to think about that.

Until I can get a different board that fully supports Wolfdale, or another similar CPU, I can't be sure.

The thing is, I've never, ever, ever come across a faulty Intel CPU so I don't what sort of symptoms they'd exhibit. That's what I'd like to know, are these Machine Check Exception errors just an indication of board incompatibility or a defective processor? Yes, in theory the board with BIOS F6 should work but it *is* Rev 1.0 and maybe I'm just unlucky.

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

Ahhh ok, sounds like maybe corrupt OS then!

Did you try F8 options at OS start, so you could try last known good? If not try that, and or safe mode.

If neither help try a clean install. Was this disk originally installed on this board? What is the OS and what service pack?

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

The Operating Systems aren't corrupt because if I use a different CPU everything works.

Here's what I get with the E5200 and booting Linux:



I put the MCE codes through mcelog --ascii and all it says is:

CPU 1: Machine Check Exception: 5 Bank 0: b200004000000800
CPU 1: Machine Check Exception: 5 Bank 5: b200121020080400
CPU 0: Machine Check Exception: 4 Bank 5: b200121014040400
CPU 0: Machine Check Exception: 4 Bank 0: b200004000000800
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor

Trying to boot Windows 7 gives me a BSOD and WinXP SP3 just restarts before it's finished loading.

What do you think? Faulty CPU? or weirdo Rev 1.0 board..?

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

It suggest memory error, try running memtest86+, if you get errors or it freez try with one of the other processors.
Check The E5200 pins, if they clean and intact.
I lean towards the CPU.

Re: GA-EP35-DS3L and E5200 fails with Machine Check Exception error on OS load

The memory is ok, but I managed to test the E5200 in a friends motherboard with different RAM, and it still fails with Machine Check Exceptions, so I guess it's got to be a faulty CPU. Time for a refund or replacement.

Thanks for all your replies and help. Really good forum you've got here. :)

Contacted Gigabyte and they said do a fresh install of the OS, hmm, don't think that'll work because even Linux LiveCDs crash on boot up, except for a really old one from 2005 which actually worked (once) but detected the CPU as a Pentium 3. So I've sent Gigabyte the MCE decode log, waiting for a reply ;) Got a refund and get to keep the chip, so might be worth experimenting a bit more, maybe..

Is the CPU too old to be RMAd?
