Hey there,

I've been setting myself up for a spot of overclocking on these components:

Intel E5300
Gigabyte G41M-ES2L
1x1gb Kingston 667mhz cheapo rubbish ram.

Now the wierd thing is, I set everything up manually, all stock settings for now, checked it was stable, and then it was time to start overclocking. My first rule is always change 1 thing at a time, so first thing was to drop the memory multiplier from 3.33 to 2.66.

This meant that my 667mhz ram would be running at 533mhz, but it wouldn't even boot? But if I leave the multi at 3.33 with an FSB of 210, running the ram at 700mhz, it does boot?

Any ideas on what the problem may be? Just bought 2x1gb of 1066mhz DDR2 on MM, so when they arrive I should be able to run the default multi and overclock it on the FSB, but I was just wondering if anyone has had any experience of this board and could offer any idea as to why changing the multi would have made the ram unstable?
 
Sorry guys, forgot about this. I would reply to you all but I don't have time I'm afraid! I solved it anyway. I got 2x1gb of 1066mhz ram, and upped the FSB to 266mhz which I think Wayne recommended in one of his posts?

Anyway, it's running lovely and stable at 3.4ghz using stock voltages now.

Wayne, when I said I changed 1 thing at a time, but set everything to manual, I mean I inserted the stock settings manually all at once, made sure it was stable, then started changing one thing at once. :)

Again, thanks for all your help and advice.
