Cheapest 1600fsb motherboard
Hi guys I currently have a Gigabyte P35-GA-D3SL Motherboard and I'm overclocking an E6750 (2.66Ghz) processor, as far as I'm aware the most fsb mhz I can get on this motherboard is 400 which gives me 3.2Ghz (right now I've got it on 2.9...Ghz) as the multiplier is locked at 6 or 8, but I've read that this processor is capable of 3.8-4Ghz which I'm guessing requires a 1600fsb motherboard. I'm considering the upgrade so I was looking for recommendations, money is an issue so I'm looking for the cheapest I can get. If I've misunderstood some fundamental principal of overclocking that would allow me to overclock this processor more on this motherboard please let me know!
If not please recommend a cheap overclockable 1600fsb motherboard (available from a UK retailer).
I'm using 2x2GB Reaper X 800Mhz RAM (I want to overclock these to 1100Mhz), a Zalman 9500AT aero flower thingy cpu cooler, ATI HIS4870 GPU and a 580W Hyper PSU.
What do you guys think of the asus p5K se?
Re: Cheapest 1600fsb motherboard
Hmmm well if my maths is right with a stock FSB of 266 for those processors it must have a 10x multiplier to be 2.66Ghz (stock). So that in mind you should be able to set your multiplier to 10 and fsb to 400 and get 4Ghz, with your RAM on the lowest divider it will run at 800Mhz, which is stock for it. But getting that sort of speed will need a lot of voltage to the CPU and air cooling probably wont cut it. 3.6Ghz is probably a more realistic target, (but give it a go and see what happens it might be fine, ive not got a dual core that high myself).
Im not sure why your multiplier is 6-8, possibly its set wrong the bios and also speedstep may be running the bios as well which is dropping your multiplier to save power. I would recommend turning that off.
So in summary I dont think you need a new mobo :).

Um...stock fsb for this CPU is 333, I think everything below the e6600 had 266 stock fsb?

Ah right, well then thats my bad, I thought that was only the extreme edition dual cores (I skipped most of them and went straight to quads). Never the less I found this review where X-bit labs got your motherboard with a dual core to 490FSB:

I think you got the 3 and the S the wrong way round in your 1st post. You may need a bios flash but I still dont think you need a new mobo.

Wow that's bizarre, I really thought max fsb on this mobo was 400! I'll give it a go and let you know but i think i need to update my BIOS first, cheers!
