Miraito Posted October 14, 2007 Author Share Posted October 14, 2007 I experienced the exact same problem with Corsair's TWIN2X2048-8500C5D. I did a BIOS update from version 1.0 to 1.4 and the system would not boot. At first I thought I had a failed BIOS update and proceeded to re-flash the BIOS but still no luck to boot. There was no VGA and LEDs indicated that the BIOS was being loaded to memory or indicated at times a memory failure. So I brought my PC to a friendly computer store, tried it with some cheap RAM and boom, it worked fine. But there is a longer story behind this... Three weeks before I did a BIOS update, when I received all the parts for my system, I had received bad RAM upon arrival (I didn't even get VGA output so forget about a memtest.) So I went through the RMA and got some new, same model, RAM from Corsair. Tried it, and it worked fine for two-three weeks. So after that BIOS update, resetting the BIOS to the default settings using cheaper RAM, the system would finally boot. Sounds like its fixed now right? Well apparently not... When it would get to the Vista logon, or soon after logging in, I would get a BSOD indicting a DRIVER IRQL NOT LESS OR EQUAL error which, if searched on Google, tells me its a RAM problem. So here I am again with bad RAM -- strike number 2. Since it seemed that the RAM was capable of at least booting to the Vista logon, I popped in my Ultimate Boot CD to do a memtest (v3.3). No surprise, over 15 000 errors in less than 30 minutes. I'm just about to lose patience with Corsair... Now I am running my PC as I am writing this post on $100 800Mhz 2GB RAM compared to 3 times the price I paid for the slightly faster Corsair RAM that FAILED ME TWICE and cost me $40 for Express shipping with FedEx, plus the downtime, and I need to go through that again? *sigh* Advice for those with this mainboard (MSI P35 Platinum): always have a cheap and slow RAM handy if you don't want downtime getting new memory from Corsair.

Wired Posted October 14, 2007 Share Posted October 14, 2007 DRIVER IRQL NOT LESS OR EQUAL does not always mean memory problem, Test with Memtest86+ instead of Memtest v3.3. Link to comment Share on other sites More sharing options...

Miraito Posted October 14, 2007 Author Share Posted October 14, 2007 To what end? You are saying if I run a different memtest version I would not get any errors? I'm skeptical it would make any difference. And if the BSOD error was not a memory problem, how can you explain it works with different RAM but not with the Corsair RAM I have?

Miraito Posted October 14, 2007 Author Share Posted October 14, 2007 Just for the sake of argument, I burned Memtest86+ v1.70 to see if there was any difference... well yes. More errors.

Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 Load optimized defaults and set the Memory Voltage to 2.2 volts and then set the timings to 5-5-5-15 (CAS-tRCD-tRP-tRAS) and then test the modules one at a time with http://www.memtest.org! Please allow memtest to run 2-3 passes on each module. If you still get errors, we will be happy to replace them! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.
