OK, I have a very poor mobo for overclocking, but this doesn't seem right.
It's an ASROCK Wolfdale1333-GLAN/M, with an Intel E2140 and 1GB OCZ DDR2 2700. I bought it for a HTPC so overclocking was not on my mind, but the CPU is meant to OC well so I thought I'd give it a go. What I find is, upping the FSB from 200 to 250 while leaving the PCIE at 100MHz, it won't boot at the increased speed, but sticks at the stock 1.6GHz (8x200). But if I set the PCIE bus higher, to 110, it boots fine and I get a stable overclock.
This isn't normal is it? Why should the PCIE speed affect whether it can overclock the CPU? I think I could go a lot higher with the CPU, but I'm afraid to overclock the PCIE bus, I might break it!
Any thoughts (other than "get a better mobo, cheapskate")?
