on the amd site it says that the athlon xp 1800+ runs on a 233 fsb, so why can i only set it up to 142 without it going nuts? and is there any way to get this thing to let me change the multipliers? im running it 100 mhz faster, recognized as a 2000+ now, but i want to lower the multipliers and raise the fsb more, i hear that makes your comp faster.

The XP1800+ runs @ 133 FSB.

As far as changing the multipliers, etc. it depends on the motherboard and CPU.

soyo dragon lite kt333 and athlon xp 1800. it has an option to turn the multipliers up, but if i do, and check cpuid it stays at 11.5 whereas i have it set to anything else.
also, if anyone has any software for checking the cpu temps it would be nice.

What ever the bus frequency is set to, it's multiplied by 2(AMD with a 266FSB = 133 x 2 = 266, A P4 with a 400FSB is 100 x 4).

to change the multipliers, you have to manually fiddle with the actual processor, to my knowledge. AMD lock the multiplier so it cant be changed. there are ways around this, but i wouldnt recommend doing them unless you have knowledge of the chip and a whole lot of money incase if you mess up :)

aight. SOME amd's are unlocked (more frequent lately with T-bred (small core) processors. those you can change the multiplier (with appropriate memory, Vcore adjustments, etc) IF the motherboard and PCI devices will run at your preferred settings..if they are NOT unlocked, (STFW), you can UNLOCK them by filling gaps where lil' wires have been laser cut, (tedious, pointless, WHY do you think they're locked?), for all the hassle and risk, its Simpler and Cleaner to BUY an unlocked one, and use it to play with. keeping your STOCK processor for the day you fry the experimental one..
