Bus Speed?

3 posts by 3 people · 25 Aug 1998 - 09 Sep 1998

Hi All... This may sound off-topic, but the reason I'm asking is to improve my computer's performance for better simming... so it IS on topic? Anyway... I've been "told" that Intel's Pentium series chips are limited to 60 mhz bus speed. Is this on the up, or is it computer shop bull? Reason for asking is that I have a TX based mother board that allows 100mhz bus speed... but if my P233MMX can't get past 60mhz, then what's the point? Also, assuming that the P-chips CAN speed faster than 60mhz, how would I change the bus speed... at my BIOS screen? Any input appreciated... Andre
Yea the computer shop really doesn't know what there talking about, it really 66bus. BUT you can overclock the chip and run it at a higher bus speed if your motherboard will let you. Right now you are running a multiplier of 3.5 and bus speed of 66Mhz, 3.5x66=233Mhz. If your motherboard lets you run higher bus speeds like 75 or 83 it will look like this: 3.5x75=262Mhz and 3.5x83=290.5Mhz. But this produces a lot of heat and you must keep the CPU cool with a really good heatsink/fan. But the TX chipset can not run 100Mhz bus. The only Intel chipset that can run 100 bus is the BX chipset. Depending on the motherboard, you change bus speed by either changing the jumpers on the motherboard or in the Bios. There are VIA chipset socket 7 motherboards they let you take an AMD K6-2 to 100bus. The P233 is not garenteed to work at 100 bus on those motherboards though. But some people managed to get a few P200mmx's running at 100bus on those motherboard. But its not a realistic thing to do. Arthur s t e a l t h r a c i n g http://www.***sys.com/stealthracing.html

Older Pentium motherboards run at 66Mhz, the latest boards (Intel P2 350+) run at 100Mhz which will be of some use to your system (cuts out bottlenecks when CPU calls on memory etc) And YES you can change your BUS SPEED on some BIOS screens. -Steve Hood writes -- Stephen.J.Hood
