e6600 calculation question.

[Suno No Tate]

I ran my e6600 at 9x320 FSB with a frequency of 2.88ghz. The system showed that. Then I was playing around and decided to run it at 7x380 FSB. When the system reloaded, it showed a core frequency of 3.4 ghz. I checked easy tune, and with the windows hardware and everything says 3.4 ghz. What's going on here? Can I actually believe the frequency? I'm using a ga-965p-ds3 with the latest bios.

not like we don't believe you. but if you would send us a screenshot our way with CPU-z's main window up it would help a ton.

To my knowledge the Conroes have fixed multipliers and your multiplier is set to 9. So if you set your FSB to 380Mhz, then yes, your CPU will be running at 3420Mhz. So yes, your e6600 is running at 3.4Ghz, Conroes overclock very well, just make sure it's stable and the temps are reasonable under load. :)

NO whats happening is this

WINDOWS ALWAYS ONLY SEES 9 MULTI

you set 7x380 for 2660 but windows only sees 9xXXX so 9x380 is 3420 your not actually running that speed though you are running the speed of 2660, cpuz will always tell the truth. and so will the bios...

CPU z reported about 2.5ghz so it seems windows is screwing it up. Funny thing is the bios screwed it up too and reported 3.4 ghz upon loading. I restarted more than twice when it was doing that and everytime it gave that same speed. Anway, I lowered the multiplier to 8x and bumped the fsb to 385. Works quite stably and both windows and the bios are reporting the correct speed. I ran orthos for just a little while, but so far all indications are good and the vcore and temps are extremely low. Anyway, before I ran it at 9x320 (and worked hard to get that too) but for some reason I can run it at 8x385 with much greater ease. I've tried before running it at 8x320 with the same settings as today and it struggled. Its like today my board decided to start living up to its name. Anybody know why? I'm thinking ghosts?

350 fsb seems to be a stable max with the 9x multiplier. Anyone know any tricks to get a higher fsb frequency with the 9x in effect? I don't want to loosen the ram timings anymore and raising vcore doesnt' seem to affect the stability at all (just makes things hotter).
