E5700 and mobo question

post #1 of 13
Thread Starter 
I just purchased an E5700 and Zotac nforce 610i mobo combo deal to serve as a folding rig. I noticed that the mobo supports 1066 and 1333 fsb. The processor is is 800 fsb. My question is will the mobo and CPU automatically adjust the multiplier and fsb to make the cpu run at its stock speed of 3 ghz? Also, I plan to over clock this as well. So my next question is, with the difference between the FSB of the products, what is the best way to overclock this CPU? I am thinking by just keeping the FSB low and increasing the multiplier. I am a fairly experienced overclocker but I have never dealt with this disparity between CPU and Mobo FSB. Any help would be greatly appreciated.

EDIT: I do plan to Watercool this CPU with the extra WC parts i have laying around. I know it is not necessary to wc this CPU but how can ya beat WC'ing for free? LOL

It'll just run at 800MHz FSB.

would it hurt to Bring the FSB up and the Multiplier down? Would this increase OC'ability?

Does that response apply to the first or the second question? Or both? LOL

E5x CPU's hit an FSB wall at around 333 (1333). So if you lower the multiplier and try to clock high you will hit the FSB wall sooner.

Probably would hinder overclocking... If I remember correctly the 5x00 series hit FSB walls around 350 - 375 FSB, so the higher multi helps with higher clocks..

Okay, So just keep the multi up and the Fsb low. Thats the ideal situation for the CPU. Now, as far as the Mobo is concerned, will running it below its spec speeds of 1066/1333 fsb upset it? My logic say No it will not hurt it all and will in fact make it happier because it doesnt have to work as hard, but I just wanted to make sure.

EDIT: WHat kind of OC can i expect from this CPU....it will be just for folding....nice and cool and low power.

Well higher FSB = better performance, but how much is probably negligible...

Best thing is to just test and see, the Highest CPU MHz is usually the best performance so work on that first. Then figure out the FSB : DRAM ratio..

But its just "rated" at 1066 - 1333, doesnt mean it has to run at those speeds. It will run cooler with less voltage at lower speeds...

And a good E5700 should do 4.0 without much trouble.. I had an E5300 that did it...

Okay. I just hope the mobo is capable of it.
