Right now I'm running: Windows 7 64 bit on: MSI P35 Neo Combo motherboard 2 gigabytes DDR3 1066 BFGtech Nvidia 9800gtx+ 512mb 160 gigabyte Western digital hard drive 7200rpm Default BIOS version I'm not sure just how much more is relevant, so ask if you need more information on my system. Here's my problem: Today I got another 2 gigabyte stick of RAM for my computer. Putting into Channel B results in a strange error. It tells me that "the performance of overclocking is failed" and refuses to boot windows. It only offers that I can open up the boot menu or go into the BIOS to edit settings. I deduced that since the memory chip wasn't dead that I was having an issue with the BIOS. I did some research and found that my BIOS was outdated. Version 1.7 is out and it has improved memory capabilities which I assume means that it will support 2 unbuffered sticks of memory. Attempting to update my BIOS results in another error. It tells me that the version of the file I'm trying to install isn't compatible with my operating system and that I need to check for a version of the file that's compatible with 64 bit. My BIOS update however only has one (to my knowledge) download link on the MSI homepage, and it says NOTHING with regards to whether it's necessary to have a 64 bit version of it or not. Please...someone has to have some insight here. I know someone has a clue on how to fix this. Anything any of you can offer me will be very much appreciated. I've already tried asking MSI tech support for help but they've been essentially useless thus far.
