BIOS Setting

[ahmedalmatook]

Hi I have AMD 2800 Barton and a mother board Asus A7N8X-X, the BIOS setting are;
Option 1 (currently applied)
External frequency setting 166MHz and the Multiplier is set at 12.5, in brief 12.5X166= 2075 or 2.08GHz.
Option 2
I am thinking to set the BIOS to 200MHz and the multiplier at 11 then 200X11=2.2 GHz which seems to be faster than the first setting, is that correct?, if I apply the 2nd option would my PC be a bit faster?? Would the temperature decrease or increase??
Thank you

A higher GHz speed would be a faster pc if it will boot up

In this case -> faster = hotter..

Make sure you know where the reset cmos jumper is and get more opinions before proceeding.

Thank you steve, thats why i am here... get opinions

That is known as overclocking, and a slight overclock in this case, you wouldn't see much of an improvement IMO, as you are increasing the clock speed so breaking it down it would be less than 10% OC, and yes it does increase heat the higher it goes, so if you plan to push it further and are using the stock cooler i'd be very careful and move it up a notch at a time, small steps.

thank you for the advice, I will keep the original settings

As far as I remember, the 2800 Barton is locked and you can't change the Multiplier.

I have a 3200 barton and a 2800 barton in my other systems. The 3200 I have was one of the last produced with out the locked multiplyer. I will check in the AM on my sons system to see if his 2800 is locked or unlocked I can't remember, its beeen a while sense I have messed with it. You will however and if the ram and other components can handle it get better results ocing with the fsb.

After reading a few posts around the net, it seems it is locked, but you can change the FSB to OC the system.

EDIT: I found another forum (the AMD forum) where a member said that the 2800 Bartons manufactured after September 2003 were locked. So the ones manufactured before apparently aren't locked.

thank you all, Usil you are right, my one is not locked

Generally with the Bartons, the first so many thousand off the line were not locked. Then all after that number they were locked.

The multiplier on a Barton is maxed, but not locked. You can't go higher than 12.5 with yours, but you can go lower. The FSB, on the other hand, is touchy when increased. My XP 3000 (166 x 13, 2.16GHz) would get as far as 186 on an Abit KV7 mobo, then would become extremely unstable - no matter how much extra voltage I gave the RAM and CPU. From my experience at least, setting a 166 Barton to 200 (no matter what multiplier you use) will prevent your computer from starting at all - it wasn't designed to operate at 200MHz. You might have different luck, your mobo is a good one as well.

Do not be surprised if 174 is the max either, just take it slow and easy steps to find out what it can take.

DO NOT forget, it things get james up, you can remove the battery to reset the BIOS back to the defaults. Then too, I have had the BIOS reset itself and boot back to the BIOS with ASUS mobos when overclocking.
