Cpu Speed

[Skunk]

Hi !

I have a Athlon 2600+ (FSB 333) on a A7V8X-X which is said to run normally
at 2.083Ghz, but in the BIOS (1005) I have only 4 choices for CPU Speed
(1083,1533, 1917, 2300). So I enter the CPU speed "manually" with a
frequency multiple of 12.5x and a external frequency of 166/33Mhz (12.5 x
166Mhz = 2.075Ghz). But the strange thing is that Asus Probe indicate me a
cpu speed of 1833Mhz, and SiSoft Sandra 2003 a speed of 1.91Ghz and a
multiplier of 11.5x !?!

Am I doing something wrong or are these 2 softwares indicating me false
values ? How can I know the real speed of my CPU ?

Thanks very much for your help !

Is it a barton or a thoroughbred core?
Pretty sure it's not a "Thorton"!
SiSoft seems to think you have a barton!

I think I have perhaps found the answer to my problem in this thread... :-((

11.5 x 180 = 2070

looks that way - what a bummer - locked multiplier on a kt400 chipset - you
still may be able to get the fsb up to about 180mhz though - maybe?

you have my sympathy

I never did that before. Do I have to speed up my memory to 360Mhz to
synchronise with the fsb or can I let it run at 333Mhz ?

Is there any chance that doing this can damage my RAM (a 512 DDR no name
333Mhz), my cpu or my motherboard ?

you have my sympathy

Thank you...

Thank you...

That ram will probably hold you back no matter what you do with the fsb
settings, I have one of those cpu's(earlier model), it's in my dedicated dvd
machine, I run cas2 kingston hyperx(256meg/333) with it, it smokes!
It can take up to almost an hour to do a complete dvd backup, one glitch
and you're toast.

It is better if you keep the fsb and memory in synch at a 1:1 ratio, and
increase the fsb a little bit at a time - 180mhz is pushing it. I cannot
say how the ram will perform. Hardware damage is a very very slight chance,
things will fall over long before they break. The worst case scenario
really is that some system files on your hard disk get corrupted as the
pci/agp has been taken too far out of range - but that is at over 180mhz
probably.

You may only get to the low 170s - if your system becomes unstable - it has
gone too far. Two programs that will thoroughly test your system are
memtest - www.memtest86.com and prime95

If the ram can not cope with any change and you can set the fsb faster than
the ram then maybe that would help.

Not meaning to gloat but I have a KT333 chipset and an unlocked barton 2500+
getting seriously abused running at 15 x 167 (2505mhz) on air cooling
(thrashing some systems costing three and four times the money) - and
nothing has broken - yet - (touch wood).
