I’m curious about these because I want to push high FSB speeds (over 500 MHz). The main reasons are just a quirky project and turning it into content since nobody likes a slow motherboard. I won’t stop trying anyway. I’m using 30 series chipsets because there’s no strict FSB cap, only limits on board, voltage, and temperature. I’m especially interested in Q chipsets since few people run high FSBs there, so free hardware guides are helpful. Even if I don’t win a record, seeing an OEM board with crazy speeds is still entertaining. Here’s what I’m aiming for now: figure out any problems beyond the obvious need for VMOS support, adjusting VRMs or power if I want proper CPU testing, and dealing with BTX (BTU) issues. Looking forward to it!
The 40 series had boundaries? My best performance on my P45 board reached around 467Mhz. That was the maximum I could achieve continuously at that time. Spoiler: It was a Q9650 running at 4.203GHz with 4x2GB DDR2-1066 at 933MHz, operating at 5-4-4-12. I used this configuration for some time before the board’s limits were reached. lol.
That's p45 without any random FSB restrictions, same for x48. All the others except p45 and x48 had FSB limits, mainly 41 and 43 plus the rebranded Q45 (also called G43). Not sure about G45 though—I’d avoid it just in case. Probably not worth it since it’s a 45 chipset. The hardware bots for G45 are terrible, and my G31M S2C beats them all (542 FSB). I won’t waste time on that for a while. Also, isn’t 467 a bit slow for p45? It’s quadcore but I expect it to be a bit higher than 467. If you run the Gigabyte U series motherboard, they push quad speeds up to 500+ easily. My DS4P is stable at 556 on my E8400.
I don’t understand what FSB can do with a P45 chipset. I think the board I had was a Biostar TP45HP. The 4.2GHz limit matched my CPU and cooling needs. I really wanted 525-533MHz for an 8x multiplier and closer RAM speeds around 1066. I’m sure I tried, but I wasn’t very skilled then, so I didn’t adjust any settings beyond the FSB voltage. Still, it was a great system.
God help me, those units handle 600+ smoothly on dualcores. The BIOS is really poor, missing fine tweaks and giving only rough offsets—you’ll need a multimeter just to check it properly. That’s a big hurdle for observing. It’s pretty clear you’re getting a weak FSB setup on such a board. For serious testing, you’d want Vmod for voltage adjustments; otherwise, the board is great but not ideal for advanced work. Biostar isn’t beginner-friendly because of these issues, while ASUS is better for newcomers thanks to simple BIOS but lacks what I need. Giga could be a middle ground with its amazing FSB, though it takes some time to master and I’m still confused about drive settings. I’d probably stick with a pre-set unless I can get something much better.
