Gman, That was quite a tutorial on mobos. A bit technical for my knowledge, but good to know that I chose a good one. Two years ago I spent a couple of weeks pouring over a mail order catalogue to gather all the bits and pieces for the new computer! Also interesting the part re: the RAM... I was totally misinformed. I am going to take this up again with the tech people at the computer shop. I won´t be buying more memory right away, I´m broke till end of April :o)) Will check with you before I do! Another thing, 2 years ago I paid £ 45 (in UK) for the mobo which converted at the time would be, roughly, US$ 90. Did you see the price they are offering it now???

The RAM info you supplied is a good thing as it allows me to make sure you have the right stuff for your mobo's capabilities. For this particulr topic, the CPU info is not needed. Here's a picture of your mobo: http://www.hardwaresecrets.com/fullimage.php?image=7573 Here is an independent breakdown the specs: http://www.hardwaresecrets.com/article/468 And the maker's breakdown/description: http://www.msicomputer.com/product/p_spec.asp?model=K9AGM2-FIH&class=mb According to the specs, your mobo is set to handle DDR2 533, 667 or 800 MHz. dual-channel memory across two memory slots. Those numbers translate to PC4200, PC5300 and PC6400 memory. You already know that the board doesn't have a problem running the higher rating, so stick with that when you go looking for a replacement. The board supports up to 4GB of RAM, which means you have the option of getting yourself a pair of matched 2GB sticks rated at PC6400 or DDR2 800 (same thing as far as marketing is concerned). If 4GB is beyond your needs, a matched pair of 1GB sticks will do you just fine. Most techs already know this, but it certainly bears repeating here for you. The following paragraph is included right on the manufacturer's page for your mobo. ******************************** Due to the High Performance Memory design, motherboards or system configurations may or may not operate smoothly at the JEDEC (Joint Electron Device Engineering Council) standard settings (BIOS Default on the motherboard) such as DDR2 voltage, memory speeds and memory timing. Please confirm and adjust your memory setting in the BIOS accordingly for better system stability. Example: Kingston HyperX DDR2-800 PC-6400 operates at 2.0V, 4-4-4-12. For more information about specification of high performance memory modules, please check with your Memory Manufactures for more details. ******************************** What this means is that if you choose high performance RAM that is designed to use non-standard voltages or timings, those items will need to be adjusted in your mobo's BIOS before they'll run as stable as possible. Not making these adjustments may still allow them to boot up the system (then again, ...), but they will certainly not be running at full steam without the adjustments. We can discuss this issue at greater length if you're not sure what I'm talking about here.
