I have an older computer and would like to upgrade my CPU to make it a bit faster. To achieve this I recently obtained a bios upgrade from eSupport.com which was suppose to allow me to upgrade my CPU. I'll give my specs below and my question is what do you think is the fastest CPU that I could put on this motherboard? The guy from eSupport said, " You can put up to a 3.2 Ghz Amd Athlon processor in there so any processor up to that and set the FSB accordingly for that particular speed of that processor." Now why don't I just follow his advice, it's because earlier he told me I couldn't put an AMD Athlon XP 2700 T-BRED CPU on the motherboard. So I was a bit confused. My FSB is currently set to 100 but can be increased to 133. Is it underclocked by being set to 100 FSB rather than 133?

You could of get a FREE BIOS upgrade from GIGABYTE, which was unneccessary anyway, and this is the page: http://www.gigabyte.com.tw/Support/... This little piece of investigation would of informed you that you have a KT133 Chipset which does not support Palomino, Thoroughbreed or Barton CORES: http://www.gigabyte.com.tw/Support/... Unfortunately you have thrown good money away.......................

Hopefully you didn't pay for a BIOS update because they're free...all you had to do is go to the Gigabyte website & get it. http://www.gigabyte.com.tw/Support/... Your board is based on the KT133 chipset, which means you board does not support any 133MHz (266FSB), 166MHz (333FSB) or 200MHz (400FSB) CPUs. So unless your board is PCB Rev. 5.1 or above, you can NOT run ANY Athlon XP CPUs! Here's the CPU support list: http://www.gigabyte.com.tw/Support/...

orbital beat me to it, but we both basically provided the same info :-)

Thanks for the comments I did try those bios upgrades at Gigabyte but they did not work for me. The bios upgrade from eSupport only cost $29.00 so I'm not too worried about that. I originally had an AMD Duron 800mhz cpu and upgraded to the AMD Thunderbird 1.05, a few years ago, which I'm running at 100 FSB. I used CPUZ utility to give me the info on the cpu. The guy who sold it to me said it was 1.4 Mhz Thunderbird if it ran at 133 FSB. At the time I wasn't confident enough to mess with the FSB, so I left it at 100 FSB. Since it looks from your info I can't use an Athlon XP cpu, would it be safe to set my FSB to 133 from 100? If I did that would I have to change the voltage as well? I know where the jumpers are on my mobo to switch the FSB. Would this be considered overclockling or just setting my FSB to the proper setting for this cpu. My sdram is at 133Mhz. I'm assuming I would have to switch the bios to 133 Mhz as well? Here are the specs from CPUZ: Processors Map -------------------------- Number of processors 1 Number of threads 1 Processor 0 -- Core 0 -- Thread 0 Processors Information -------------------------- Processor 1 (ID = 0) Number of cores 1 Number of threads 1 (max 1) Name AMD Athlon Codename Thunderbird Specification AMD Athlon(tm) Processor Package Socket A (462) CPUID 6.4.4 Extended CPUID 7.4 Core Stepping A9 Technology 0.18 um Core Speed 1046.7 MHz (10.5 x 99.7 MHz) Rated Bus speed 199.4 MHz Instructions sets MMX (+), 3DNow!

Read the info provided, there is no support for 133fsb, period...........

OK thanks for your help!!
