why can't I get above 105fsb???????????

[dawg]

I have a msi k7t pro 2a with a duran 700. Mx 32mb card 128mb pc133 a 300 watt ps 20gig fujitsu with a super orb. Right now as I type this I am only at 39c at 105x9.5 =1000mhz @1.85v. I can even lower the multiplyer as low as 5x105 but it wont even post above 105 ever? the board goes up to 133 my ram is 133 the cpu ain't hot why can't I get even 110????

If Im not mistaken dude ( and somebody correct me if I am wrong please) that board is based on the KT133 chipset. This chipset is notorious , dispite the implications of the name, for not being able to make it to 133Mhz Fsb. I have had two boards with this chipset....a FIC AZ11E which i was only able to get to 107 despite my best efforts..and a ABIT KT7 which I was only able to get to 118 FSB. I returned the KT7 to get the ABIT KT7A..(based on the newer VIA 133A
chipset) and was able to achieve 140 FSB using the same Crucial PC150 stick. I researched this alot because like you...I was pissed that I couldnt get any higher! One thing I have heard after the fact is that If you put some active cooling on the northbridge chip..you may be able to push it further..but I didnt get to try this....Good luck!

Is that board based on the VIA 133 chipset? Im too lazy to check right now.

for some reason my a7v have a kt133a chip and able to do 133 fsb no problem.....so strange~

Probably because you have the A7V133, not the A7V. There is a difference. The A7V uses the KT133 chipset, and the A7V133 uses the KT133a chipset. I wish Asus would name their boards a little better, but what're you gunna do eh?

i m sure it is A7V b/c i m lookin at box now
and
look at this

Thanx so far guys but so far I don't see any thing helpful except the cooling of the northbridge. However My machine wont post at higher then 105 so what good is extra cooling. It is prob at 20c when you do a cold boot and if there is no post obiously exrtra cooling wont help. Do you guys think mabey a volt mod will help?If yes anyone know where a mod for the msi k7t pro2-a is??
thanx

It's sadly too normal for a k7tpro 2/2a not to reach any higher fsb's tha about 105-107. I dunno if the volt mod would help you, bu here it is:

Dawg, the KT133 northbridge is reknowned for it's lack of overclock friendliness in most configurations. The Vmod in the above post is a way to supply more voltage to the processor, not VIO.

There are some cooling tricks you can try to increase the FSB speed.

If you feel like spending some time on additional motherboard cooling, the PLL chip may offer you the best opportunity to achieve a higher FSB speed.

Joe's how-to for an A7V is found here (http://www.overclockers.com/articles198/), but can be adapted to your board.
