MSI K7T Pro (v1) motherboard with AMD Athlon 1.1Ghz CPU; shows up as running at 1250Mhz
I recently bought a second-hand MSI K7T Pro (v1) motherboard and Athlon
1.1Ghz processor (seperately) from ebay; everything works fine, but I'm curious as to why the processor shows up as running at 1250Mhz (at the POST screen and using CPU-Z (software that gathers information on some of the main devices of your system)). The motherboard's FSB apparently supports 100MHz (200MHz Internal System Bus) and I have put in three sticks of PC133 SDRAM. The motherboard's spec is he http://www.msi.com.tw/program/ products/mainboard/mbd/pro_mbd _detail.p... My best guesses are (a) the CPU has been overclocked or (b) the motherboard has locked the multiplier to 12.5. There isn't a way to change the multiplier in the bios (this is according to MSI & from looking myself), only the FSB (and that would mean raising it). There doesn't appear to be a jumper to do this either. Anyone know why I'm getting this higher speed ?...and if it's possible to lower it (underclock) ? thanks Jim |

Someone could have moddded the cpu to a 12.5 multiplier. Someone could have modded the multiplier via pinmod or wires to socket. Or more likely, the FSB has been raised to about 113-114MHz. Lowering the FSB will lower the speed, and you could always change the multiplier manually. -- KT133 MB, CPU @2400MHz (24x100): SIS755 MB CPU @2330MHz (10x233) Need good help?

Thanks for your reply, I'll give your suggestion about changing the FSB
a go. |
