Hi i've got a KT4V motherboard i brought a barton 2800+ and i know my motherboard supports it because i rang around and asked some people. but the thing is, is that its not running at 2800+ i mean i've looked in the bios and its says somthing about 100mzh but when i try and change it, it just kills ma system so then i have to clear the bios u know switching the jumper settings on the board, if i want to get more i have to load the high performance settings in the bios and that says its a 1300 which is **** and its really annoying me. i've not really looked into the manul yet but i will to night and i will keep reading it over and over again could some one plz help me u can get in contact with me @ kl46@hotmail.com

what are you trying to change the bus speed to? You're right in as much as it shouldn't be set to 100mhz, as the bus speed for the Barton 2800 is 166 MHz. But if you're trying to put it much higher than that, then your PC won't be able to boot, which is why you have to reset the CMOS. < insert profound, thought-provoking statement here >

well im trying to get my cpu to run at the right speed so do u think i should just change the bus speed in the bios to a 166

yea im trying to get it to run at the speed that its suppose to so are u saying that i should change the speed im the bios from 100 to 166

yep, the correct clock speed for your chip is 166. The multiplier is locked at 12.5 166 * 12.5 gives you 2.083 GHz, which is the correct clock speed of your chip (I have the same one). < insert profound, thought-provoking statement here >

yea but the thing is that when it starts up it says 1300+ yea and not 2800+ and in the fuzzy logic thing i tried changing it in their but it does say 12.5 somthing but it dont say 2.083 says somthing totaly dif and i checked the cpu and it does say 2800 so its really bathling me

You should read your manual or check the MSI website: "FSB clock by default is 100, make sure that BIOS setup-->Frequency/Voltage Control-->CPU FSB clock set as 166" http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=362 Asus A7N8X-X 1800+ @8x210mhz 512mb PC3200 Ti4200/8X 128mb WDC 60GB
