Author Topic: Advice needed: Athlon TB 200/266 issue... (Read 655 times)

Greetings aces,

It's time for some system cosmetics again! I'd like to buy a Athlon TB 1'200Mhz but I have one slight problem/question:

I have an ASUS A7V (KT133 - nota,c,m,e or anything) which supports 100,133/200 FSB. Now there is no price difference between an Athlon200 and an Athlon266 and the ones with FSB 200 are very hard to find at 1'200Mhz. Found only 2 (expensive) shops who sell em.

The MoBo does support 1.2gig but only 200FSB - will I still be able to run the Athlon266 on my board (at FSB200 of course)??? Need advice!!!

THX!!!

anyone?

Q: Is it possible to run an Athlon1.2Gigahertz FSB266 on a Asus A7V KT133 FSB200 Mobo???

PLZ...

No idea. Why don't you email AMD and ASUS?

Hiya's,
YES you CAN run a 266 on a 200 mobo

Buy the 266 version cpu and it will run just fine on either speed chipsets

Buying the 266 version will give you full 133 capability if you were to upgrade to say a ABIT KG7 266 DDR type mobo
And on your present mobo it will run just peachy at 200 chipset speed

Hope this helps

Have Fun

I have the same board

I was wondering if upgrading to a 266 board with a 1.2 vs staying with my 200fsb board and a 1.2 would be a huge difference?

Another words is it worth upgrading the mobo at the same time as the chip?

First of all, running a 266 FSB chip on 200 FSB board will result in less Mhz unless you unlock the CPU and change the multiplier..

Secondly, lower FSB speed affects performance negatively. The difference can't be called huge, but it's definately noticiable (why else would the manufacturers trouble themselves with higher clock speeds anyway)

Motherboards and DDR RAM are quite cheap atm, so I'd get an AMD761 based or even better, KT266A based mobo when upgrading.

If you want to save money, get only a CPU - but notice that running it lower than default FSB without unlocking it will drop your clock cycles from 1.2Ghz to 900Mhz F.E.

for me that would work.. bigger chip now and a couple of months faster mobo

tks

Hiya's,
If soon you are going to upgrade to a new mobo u may consider the Abit KG7 (ddr via/amd chipsets)
And the upcoming Asus A7266

Hope this helps

Have Fun

You can run a 266 chips in a 200 MB, but the default multiplier will be wrong. You'll have to unlock the chip and set it manually.

As for new MBs, wait about a month at least for the current kt266 boards to transistion to the kt266a (MUCH better performance). Also it may be possible to tell by then if nVidia's nForce will be as good as it's rumored to be. Asus models would be: (kt266(a)) A7V266 and nForce A7N266.

Oh yeah, better make sure also that your current motherboard Bios supports the use of the new CPU. If your motherboard doesn't reckognize the CPU it might lead to unresolvable problems, forcing you to upgrade the mobo anyway. In the worst case, the mobo can feed the CPU with the wrong voltage and kill it. If I was you, I'd save enough pennies to buy them in a total package.
