Compatibility with LGA 775 CPUs
Compatibility with LGA 775 CPUs
It has two distinct CPU generations compatible with it. The Pentium 4 can be upgraded to a P4 model using HT, while the Pentium D Core2Duo supports moving to core2quad. I always suggest the Core2Quad Q6600.
It depends on the chipset and board you have. For older 8xx or 9xx chipsets, stick with Netburst CPUs—some 9xx models support 65nm and 45nm cores, though 8xx core compatibility is unlikely. With 3x chipsets, they should work fine. 4x chipsets generally don’t support Netburst below 200FSB, but I’ve seen a P4 631 to 5.65G on a P5Q (BIOS only), so they might be okay too. As for your board, most 4x models other than P45 and X48 are unreliable unless you’re recycling them. If you plan to do FSB testing, it’s probably best to avoid those older boards.
My Rampage Formula handles 600fsb without issues. I need a faster RAM speed because my PC8500 struggles with more than ~603MHz using an e8600es. It’s a DDR2 board, but I have plenty of DDR3 available. My x3360 board only supports up to 475fsb, which is disappointing.
Relies on the specific board configuration. My setup used an Infinity Dark DFI with a 775 chip, but there was a limitation—the BIOS didn’t fully support all 775 variants at once. I spent some time troubleshooting, eventually realizing I needed to update the board’s BIOS to accommodate different 775 models. The issue depended on the chip era and type. If you encounter problems with a 1333 chip failing while an 800 functions, updating the BIOS might help. However, reverting from a newer chip back to an older version could resolve it if the original board supported those changes. I noted that some boards have modded or specialized BIOS files, and checking for those could be useful. The sources I mentioned were reliable, but the full picture is still evolving.
