Setting up Athlon 2400+

[hnewhous]

When I started my computer today the BIOS screen came up. I have an Athlon 2400+ and was wondering if anyone could help me fix the set-up. I set the clock multiplier on 15x and set one of the other settings (bus maybe?) on 133/33. It gave me a frequency of 2000 MHz which I think is correct. However if I look at the properties for my computer once Windows XP boots up, it shows that I have an Athlon 1700+. Will someone please let me know how I can fix this?

Run cpuid, a free download. A normal 2400 is multiplier locked (unless it's a mobile), and the fsb is 133.

Thanks! I ran cpuid and it said Athlon 1700+. Then I turned my computer off for a few minutes and when I turned it back on it came up Athlon 2400+.

Also, do you know how I should set the cpu/mem frequency multiplier? My options are 1:1 and 4:3.

Depends on your RAM. All numbers are approx, your ratios may be reversed:

PC 2100 DDR 266MHz think of it as 266/2 (Double Data Rate) = 133 so you run 133:133 = 1:1

Similarly:
PC 2700 DDR 333MHz think of it as 333/2 (Double Data Rate) = 166 so you run 166:133 = 5:4 IF that is RAM:FSB. 133*(5/4) =~ 166

Since you say that the only other option is 4:3, I guess that could be if you turn up the fsb from 133 to 150
WHICH you probably need BETTER COOLING for
or it could TRASH YOUR CHIP - read up on overclocking first! here

Then that would be 4:3 with
PC 3200 DDR 400MHz think of it as 400/2 (Double Data Rate) = 200 so you run 200:150 = 4:3 IF that is RAM:FSB. 150*(4/3) = 200


There may be BIOS settings or hardware modifications you can do on your chip to unlock the lower multipliers so you can get higher FSB, but may want to wait on that...

Running 1:1 is optimal all else being equal, but a high FSB and lower multi (as long as you can get about the same overall MHz) can speed everything up, including being able to run 1:1 with faster RAM
