Will a Q6600 run at 2133mhz FSB, or is there an FSB limit?

Hi, i'm new to OC'ing but i would really like to know if its possible to run a Q6600 @ 2133mhz FSB as i just brought an Asrock P45R2000, i know its not a great mobo, but on Hardware Canucks web site this mobo is running an E6550 @586mhz(2344mhz) FSB! Is the only limiting factor of the FSB for the Q6600 the mobo or does the Q6600 have a top FSB limit? Any help in explaining this would be really appreciated, cheers.

You'll hit the thermal limit before you reach your mobo's FSB limit if it's a q6600. The CPU itself doesn't have a FSB "limit" it's up to your mobo's capabilities and how cool you can keep the CPU.

Considering the Q6600 at 586FSB would be doing 5.274Ghz (9x586 = 5274), you would need liquid nitrogen or something lol.

The highest a q6600 can get on a good air cooler is roughly around 3.6-3.8Ghz(400-422FSB). Dunno about water cooling but I doubt that it's much higher than 4Ghz.

as far as im concerned, you would probably need some insane cooling and be one of the lucky few with a low as hell VID to get that kinda of fsb with a quad...

maybe he has 1066 ram and wants to use it to full?

yup i agree wiht zorg, down clock your ram so it is syncronous with your CPU, so down to 533, then OC from there, i would imagine that 3.2 would be good that way if you have ddr2 - 800 then you are stock for the ram so you wont be getting memory errors, and it wont be the restricting factor. and anything above that is a plus.

Hi, thank you all for the quick replies and i wanted to run the Q6600 @ 6x533 (3198mhz) so i can make use of my ddr3 1333 ram underclocked to 1066mhz so i can have a cpuram ratio of 1:1, the reason why i want to do this is because i cant afford an expensive set-up but it would be nice to make my PC run fast, just to see what i'm missing out on if i had the money for a real fast PC!

Hi again, i forgot i was gonna try this with air cooling (xigmatek s1283+Antec 300 case) or is this just a pipe dream due to the heat factor?

OK, cheers thats good to know thanks.

Err, no im waiting on my new case to arrive today as my case is old, sad and bad, really bad. But when i do i will try to post again to tell people the results good or bad!

Unfortunately you wasted your money on the DDR3. The Q6600 is not that sensitive to increased RAM speed. You may get a little more due to the increased FSB at the lower multi but I suspect it will only be noticeable in benches. Since you have it you might as well play. The increased FSB/RAM speed will put more stress on the mobo, so run different settings to determine whether you "feel" like the additional stress is worth it.

Since you are new to OCing, I suggest you do the intermediate OCs that I suggested above and test load temps before moving higher.

Use Prime95 small FFTs to load the CPU.
Use Real Temp 2.75 Beta to test the core temps.

I strongly suggest you read these links as well.
Core 2 Quad and Duo Temperature Guide
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1

Be careful you can easily significantly shorten the life of the Q6600 at 3.6G.

Not a problem at 3.2G for the CPU, assuming temps are kept in check. I was referring to the 3.6G OC that was mentioned.

I don't expect that the FSB of 2132 will have a deleterious effect on the mobo. This would be dependent on increases in voltages, and resultant heat, to keep it stable.

Keep an eye on your Northbridge temps.

You might just want to stick with the 3.2G, 8 multi, 1:1 @ 800, but whatever makes you happy.
