hi, im new here and just looking for a little bit of advice. my hardware knowledge seems to be a bit out of date, i was in my element with the k6-2 chips and have become a bit rusty lately. i have an amd sempron 2400+ chip, socket a and am wondering how they mhz/ ghz are worked out these days for sempron processors and maybe even the athlon versions too. i know its not by number. lol thanks in advance.
The speed for CPU's is the result of the FSB or HTT (for Athlon64 architecture only) being multiplied by the CPU's multiplier. If the CPU uses an FSB of 200MHz, and has a 9.0 multiplier, you have a 1.8GHz CPU. The tricky part is knowing what the FSB really is. The example I gave is applicable to the Athlon64 architecture. The Socket A design is pretty traditional. FSB x (multiplier). Pentium 4's and Celeron's based off the P4 design (basically, any Celeron 1.7GHz and up) uses a quad-pumped FSB. The base FSB is multiplied by 4, so if the FSB is 400MHz, the base FSB is 100MHz. The base FSB is what you use in combination with the multiplier to determine your CPU speed. If you overclock via the FSB, your quad-pumped FSB goes up 4MHz for every 1MHz you up your base FSB.
The performance ratings are based on the clock speed as well as cache. So you can't really surely say how fast it is in clock speed by performance rating. The 2400 is 1.6GHz I think. Get [google]CPU-Z[/google] to check.
thanks both. the reason i cant simply do that is cos i have it set at 2000mhz in the bios. strange but when i installed the processor and m.board i could only choose what speed it ran at. i chose the highest specified setting (2000mhz) and carried on. it works but i have a slow boot up. i was wonderign if that is related to me runnign thsi too fast. i went to a computer fair for soem parts today and asked a vendor there what the sempron + models ran at and he said the 2800+ runs at 1600 mhz so i started wondering. lol thanks for both ur answers. im new to overclocking and so i guess i must have accidently overclocked this sempron. lol :ff:
Okay, The Semprons use a 166MHz FSB Sempron 2400+: 1.66GHz, 10.0 multiplier, 256kB L2 cache Sempron 2500+: 1.75GHz, 10.5 multiplier, 256kB L2 cache Sempron 2600+: 1.83GHz, 11.0 multiplier, 256kB L2 cache Sempron 2800+: 2.0GHz, 11.5 multiplier, 256kB L2 cache Sempron 3000+: 2.0GHz, 11.5 multiplier, 512kB L2 cache
