Re: [OC] Q6600 Help
Ideally, you want a 1:1 ratio between FSB and memory. So yes, you'd do a 9x333 multiplier, so run the RAM at 667.
There is a modest increase in performance with a 1:1 ratio. The newer memory controllers generally do a good job of hiding the latency penalties.

8x400 should be easily attainable with proper air cooling.
Slap in some DDR2-800 sticks and you're good to go at 1:1 FSB:RAM speed. |

Good might shoot for that then since I did get a after market cooler. Anyone know the default voltage values for the g0 stepping? I keep finding the range, but not the default.
Also I shouldnt have to change the memory's voltage correct? The specs on newegg for the g.skill 800 i bought only goes up to 1.9 |

| It's a range because each chip has a different value, I guess based on the quality of the chip to run at the stock speed.
Seems most GO's are in the low 1.2v's.
Google Q6600 VID and there are a few threads with people posting their VID's. |

I wish you luck! I got a dud Q6600, which won't do 400x8. The only way I can get it stable over 3GHz is to run it at 356x9. I seem to be in the minority, though, so you'll likely be able to do 400x8 no problem.

| said by hsindogg :Sorry to hijack the thread, but what are your other components....have you tried for help? Yep, I've had a couple of threads about it. It's definitely not the MB, because the MB does 400+ FSB with an X6800 (actually, an engineering sample X6900). The RAM I had in there was 2x1 DDR2-800 G.Skill stuff that supposedly would do 1066 with 2.1v. But, recently I built a 2nd box and bought new RAM (PC2-8000) and even with that it doesn't work stably at 400x8. I run mprime (prime95 for FreeBSD) and it gets rounding errors unless I drop the FSB. I haven't tried finding the point where it craps out between 9x356 and 8x400, since I'm relatively happy with 3.2 GHz.
