Bad Chip

[holymonk]

Do you think I have a bad chip?

I can overclock my CPU to 4.2 with the little switch on the motherboard. By increasing the core voltage, to 1.37 I can push the chip to 4.4 Ghz, stable.

Anything overthis, I seem to encouter problems, at 4.6, when running IBT, i bluescreen, even cranking up to 1.38volts.

At 4.8 at 1.4 volts, the pc 'double boots' and hangs when loading into windows 7.

I have updated my BIOS to the latest beta as discussed in the MSI thread.

The chip is running pretty cool, 33degrees idle.

Is there anything else I can do, or do I just accept 4.5ghz is probably my limit?

Have you read over the MSI OC guide on here for sandybridge? Could be that your just missing a setting like LLC...

I've found if its a D1 revision you will struggle to get more than 4.5ghz.

For instance my D1 wouldn't do 4ghz without a voltage bump but my D2 happily does 4ghz just on moving cpu ratio.

I had read this too about the D1/D2 revisions, but as it turns out there was no hard evidence to back it up. I'm still a firm believer in it being the luck of the draw, I have a D2 2600k, clocks high at low volts, friend has a D2 2600k that will only get to 4.4ghz on the same volts as I require for 4.8ghz - same motherboard too.
