Q6600 Multiplier question

[xxceler8]

I noticed in order to get my gskill ddr2 1000 ram to work at 1000mhz speed, you have to set your bus to 333. My question is, would this effect system performance due to the fact I need to set the multiplier down 8. The system was just built, other wise I wouldn't hesitate to just OC to 3ghz, but I want to burn it in at stock speeds before doing so.

The multiplier only changes CPU speed.

And you want to do the burn in at the overclock you are going to be using.

so basicly 9x266 = 2.4, and 8x333 = 2.4.. the system would run at the same speed

Yes, they'll be no discernable real world performance difference between the two; I believe you will see higher synthetic benchmarks @ 8x333, though (not that synth benches matter).

Well, No, the CPU would run at the same speed. But since memory speed is FSB (or HT?) x divider, you would change the memory speed too when you change the FSB.

266 (FSB) x 4 (quad pumped) = memory @ 1066mhz
333 (FSB) x 4 (quad pumped) = memory @ 1333mhz.
So you'd have to run a 4:5 divider at 333 FSB to run the memory at 1066mhz.

Simple, huh?

Umm, you need to buy a new calculator. 8x333= 2,666 Mhz. Good luck with your overclock, though.

Well, I'm an AMD guy. That Intel memory stuff confuses me!!!!!!!!

To the OP, the numbers may be wrong, but the concept is correct, huh myocardia?

Well the GSkill website states if you need 333 bus to run the Ram at 1000mhz. With stock settings, my ram is only at ddr-800. It doesn't mention 1333mhz
