I bought a 1.4gHz AMD Athlon OEM chip with 200FSB and I am very confused about what will actually work with my computer. Supposedly after reading support info from the site I bought it from, if my chipset is a KT133, then there is a double rate or something with Athlon where I can buy a 266FSB. Okay is that true for a KT133 chipset? If it is true, I screwed up and bought a 200FSB when I shoud have bought a 266FSB. How do I change the settings in my mobo in order to support the 200FSB?

It would help if we knew more about your motherboard.
Who is the mfgr and what model# ?

Oh, this totally sucks!!!!

This is a MicronPC board and I bought the CPU from Thompson's Computer Warehouse. I called them and a very knowledgeable guy recognized my board right away. He said that Micron tried to dump this off on them about nine months ago because the reality is that even though it is supposed to support 266FSB, it will not support anything beyond a Duron. It will not POST at anything above like 900gHz. I am stuck having to buy a newer board and power supply but the guy was very nice and gave me an RMA with no questions asked. Just on a side note...I highly recommend Thompson's Computer Warehouse because their prices are almost too good to be true and their stuff is quality. tcwo.com

900ghz hmm... sounds fast enough to me :lilwink

[Rick]

Yes, chipset is KT133 but in Athlon, you have a "Double Data Rate" which means that it supports 266FSB. See quote below.


[quote:0f40e8e2c1]First, we would like to clarify where the 200 and 266 MHz front side bus speeds come from. All Athlon CPUs use a "double data rate" that doubles the amount of data that is sent and received on the front side bus signal. The front side signal can be either 100 or 133 MHz, thus the CPU's front side bus can be 200 or 266 respectively.[/quote:0f40e8e2c1]

Yeah Micro...would have a great supercomputer but it would burn my whole house down if I put it in my little case. Lets try again...900mHz.

Rick:eek:

[Azriah]

If memory serves me correctly, the KT133 chipset is a 200mhz FSB.
The KT133A is a 266mhz FSB.

I hope that helps

Via Chipset would nned to be a KT133A for 266MHz FSB support KT133 only supports 200MHz FSB

[Rick]

Thanx for all your help guys...got this settled by sending back the chip for a 266FSB and I have bought a new full atx mobo that supports it.
