I'm extremely confused. CPU speed is a function of FSB X the multiplier. I'm well aquainted with this notion. I've been pushing the limits of these two variables with my Athlon XP 1700+(11X133=1.47) for some time now. It's fairly stable at 1.96 (13X151). But XP's are available in bus speeds of 333 and 400 MHz. A 333 2600+ with a stated clockspeed of 2.08 should run much faster than that. The multiplier for a 266 (133) 2600+ is 15.5. But if the same multiplier is used for the 333 (166) FSB version you get 2.58. For the clockspeed to be 2.08 the multiplier must be 12.5. Does the multiplier decrease accordingly in a 333 CPU? A second question: When a FSB overclocked system crashes is it the CPU or the memory that fails? Or, if a 333 bus speed processor is put into a motherboard intended for 266 FSB can that system be FSB oc'ed more reliably than the original 266 CPU? I need a new processor. I was going to buy and unlock a 2600+ 266. But the Upgradeware XP-TMC socket adapter allows you to run any new XP with 333 or 400 MHz FSB speed. My mobo allows the FSB to be set from 100 to 200. If I buy a 2600+ at 333 FSB will I have more capacity to oc the system than with a 266 FSB? The stated clock speeds of both FSB versions of the 2600+ is 2.13. Which has the greater capacity for speed? I assume the 266 version would be pushing the FSB barrier more than the multiplier and the 333 would be pushing the multiplier more than the FSB to attain the same increase in speed. I know this is a lot but I'd appreciate ANY help.
Thanks
