You should be running DDR2 800 or 1066 on that board to overclock, but the ram you have is DDR2 667, DDR(double data rate) means the the ram reads/writes on the up and down of the pulse, so running at 420mhz means the effective clock rate is 840mhz. It must be pretty decent quality ram if it's stable running a overclock of 87mhz just not as fast as it could be with the DDR2 1066(533mhz)

Over simplified it's the time it takes it takes for the initial memory fetch to occur for overclocking stay with 2T .
Here's the best explanation I've seen https://www.tomshardware.com/forum/17...rate-explained

It's going to be the ram because it's only 667 speed. I've been using 1066 and down clocking it to have stable overclocks.
