rich88 Posted December 14, 2005 Share Posted December 14, 2005 Hoping you can help me. I have built this machine. AMD 64 3800 ABIT AV8 3rd eye Corsair Twinx 3200XL Pro 1GB Enermax 535W PSU AGP Gainward FX5900 Ultra Golden Sample connected to 1 monitor PCI PNY FX5500 connected to 2 monitors The machine runs windows ok and passes memtest. It was built to run Flight Simulator but anything from 15 mins to 3 hrs after starting I get the BSOD with the message Machine Check Exception. I read on the internet that this error is most often caused by memory incompatibility so I'm here to ask what you think. What have I tried? Well it passes memtest. I upped the voltage on the dramm to 2.7. I changed the dram command rate to 1T. I tried turning it down to 333mhz. None of this worked. The only other thing worthy of mention is that the computer will not boot with the memory in slots 1+2 but only works in slots 3+4. Is this a memory setting problem or does it sound like the MB? Is it worth trying just one stick of the memory to see if that stops the crashing? Thanks Rich Link to comment Share on other sites More sharing options...
Yellowbeard Posted December 14, 2005 Share Posted December 14, 2005 ABIT had a couple of odd bios issues with that MOBO. Have you loaded their latest bios? I'd try that first if you have not updated. Mike. Link to comment Share on other sites More sharing options...
rich88 Posted December 14, 2005 Author Share Posted December 14, 2005 I was running BIOS ver 2.4. So I updated to 2.6. Cleared CMOS. Now the computer will not boot at all, even to the BIOS. The only way I can get any sort of boot is with one memory chip in slot 3, so I set up the BIOS, but as it starts windows I get a BSOD (protecting your hardware) and restart. And around it goes. Is my MB screwed? Rich Link to comment Share on other sites More sharing options...
Yellowbeard Posted December 14, 2005 Share Posted December 14, 2005 I would now suggest testing each memory stick individually with the test from http://www.memtest86.com for 3-5 passes per stick. If they pass, then the problem is not the memory. If they show errors, it could still be a configuration issue or a failing memory module. I help out at the ABIT Forums a good bit too. You may want to search some there to see if others have resolved similiar issues. http://forum.abit-usa.com/ Mike. Link to comment Share on other sites More sharing options...
rich88 Posted December 14, 2005 Author Share Posted December 14, 2005 Ok I tried this. 1 stick has 15000 errors on test 7. the other stick will not boot, even into memtest. They sort of worked until the BIOS update! Now I cannot even start windows. Thanks Rich Link to comment Share on other sites More sharing options...
