AMD Athlon XP 2000+running speed on A7V333 motherb

  Dunce 12:52 12 Mar 2003

My AMD Athlon XP 2000+ used to run at 1.67 as it should.
I downloaded the latest update from their site and now it will only run at 1.30 (the bios also shows a setting of 1.70 but will not run at this setting )
How can I get it to run at it's top speed of 1.67 again?
The motherboard is ASUS A7V333.

I cannot get AMD or ASUS to reply to my emails.

Hi there,

I have a AMD2200+ with the same motherboard. What updates are talking about? Is it a bios update or driver update? You should never update the Bios unless it is the completely the last resort to a problem.

You should check to see if the motherbaord is set at jumper free mode which will mean it will pick the CPU speed from default depending on the chip inserted. Can you let me know what else you did and I can try and help some more?

Does the BIOS let you change the CPU frequency settings to 133, save then reboot. As kingkenny said, is it a AMD update or a MoBo update you downloaded.

The motherboard is set at jumperfree mode.

The update was an ASUS motherboard one and was a BIOS update (I wish I had not done it now)

The CPU frequency setting can be changed to 133.

I would like to follow this thread as i have had a pc now for 6 months, A7V333 Mobo and a 2100 AMD Athlon and remember seeing in the general tab of system properties approx 1.73 Ghz and after either updating from windows or something else that i cant remember, in now reads 1.30 Ghz. I didn't worry about it too much as im having problems in other areas more important.....or could this be more important than i think?????

keeping a close eye

back to basics.

Go into the BIOS and set check these two parameters are correct.
clock multiplier is 12.5 and fsb is 133mhz = 1667

what was the reason for a BIOS Flash?

I looked into my BIOS and noticed that CPU speed was set at 1.30, hit enter and had the option to set it to 1.7 and 2.0 (rough figures). I changed it to 1.7 as it used to be and it now reads in sys properties 1.79. could i set it to 2.0?

Hope this was ok to do this.
If im just about to damage anything, let me know??, please??

p.s. Dunce, sorry to jump in, all yours. :)

square eyes - 2100AMD runs @ 1733MhZ

If you pump it up to 2GHz you will be overclocking it, so i would advise not.

I think they may be a clue in the first two lines of your post.

You say your cpu is running at 1.3 gig. Now if this was at a default fsb of 100mhz then the multiplier must be set at 13.

So 13 x 100mhz = 1.3 gig.

Your second setting at 1.7 gig would work out at

13 x 133mhz = 1.729 gig

This would indicate that the clock multiplier is set to high. If this is set to auto the it may be worth manually adjusting on the motherboard.

For the chip to run as it should be then 12.5 should be the clock multiplier.

For fsb 100 this would give 1.25ghz. chip

eg 12.5 x 100 = 1.25 ghz.

and for a 133 fsb this would give a 1.67 ghz chip.

eg 12.5 x 133 = 1.662

thx, i'll leave on 1.74, dont know why it was changed to 1.3, i assume its ok on 1.74

thx again

For the A7V333 runners out there, dont forget if you leve the board in Jumperfree mode then the suspend to ram feature is disabled.

Two minutes inside the PC, move one jumper and then set the dipswitches to the configuration given in the manual to the settings given my the villlage idiot and your away -
