Overclocking and MCH Strap(?)

ZeMole55 · 11 Jan 2007 at 20:11

Can someone please explain to me about the MCH Strap?

I have a 965P-DS3, E6600 and 2gb Geil ULL Ram.

I'm currently overclocked at 430x8 - 2.4ghz and ram at 1:1 = 860mhz 4-4-4-12.

Am I hitting the different MCH strap due to my 430fsb?

I'm just clueless about this MCH strap.

Thanks in advance.

Bump.

I've searched around and I don't really understand, please help.

My understanding of straps is that (where the board has them), is that the chipset timings change at a set point to allow higher FSB beyond that point. Because the timings are looser you loose performance in chipset intensive tasks, so you need to make up a lot of ground on the FSB to compensate.

A "strap" refers to the set of internal timings and internal bypass routes of the MCH.

The strap is set on a MCH reset via BSEL pins and latched into an internal read only register. The frequencies the "strap" changes at is manufacturer firmware dependant as virtually no-one follows Intel design guidelines regarding this.

On your system your MCH core clock is 484MHz on a 1333MHz strap. If you're happy with it, it's fine...
