Abit KT7A-RAID Latest BIOS 7N
AMD 1.4 GHz running at 1.3 GHz 100 FSB
768 PC133/100 SDRAM running at 100
This is a weird incident. I have been running at 133 until I installed a new CPU fan and a new memory. Is the FSB on the CPU? Could I have contaminated the CPU and disabled the 133 FSB? I tried taking out the old memory, and it still cannot boot any OS. I'm currently running at 1.3 GHz 100 MHz FSB. Is there anyway I can run at 1.4 GHz 100 MHz FSB? Is there a tweak in the BIOS I can do to solve this problem? Can you use 2 PC 133 SDRAM with different CAS Latency?

Could it be my memory modules are not Registered/Buffered and not does not have ECC/Parity? Could this the problem that's preventing from running at 133?

I just realized both of my SDRAM has errors according to CTSPD. Below is the output. Does anyone know how to correct these kind of problems or am I stuck with bad ram? I don't think anything is damaged.

the default multiplier on a AMD 1.4 is 10.5 as in 133x10.5=1396.5
if your fsb is 100 and your CPU shows its running as a 1300 that means you've overclocked the multiplier to 13

what are you using to show CPU speed??
The FSB is on the MOBO

I'll change memory unless the above problem can be fix.
