E6550 in a P5N-E SLI

[MeatLoaf]

Will it work, im running the latest BIOS revision

Yes it will. The P5N-E supports the new 1333fsb processors, but if you want to overclock much past 3GHz you will be better off spending a little extra and getting an E6750.

The E6550 has a 7x multiplyer but the E6750 has an 8x.

Probably the latter if you want to overclock it.

I was thinking on the 6550 for my P5N-E but unsure as I'd need an FSB of 1700 to get 3Ghz.

That Mobo will be able to push the chip well past 3gig, My 6300 has a multi of 7 and is fine at 3.4.

Whats your temps?

Whats your temps?

30 ish at idle and 60 max during Orthos with 1.6 V and an ambiant room temp of 23C, + or - a couple of degrees C depending on humidity and the like.
8800gtx and NB also on the same loop.

Nice

Ive got another Dual Rad on its way and i need to re-seat the CPU block as its slightly tighter on one side and fully lap my cpu, gonna try some Shin-Etsu MicroSi instead of AS5 and after all that i might see a little improvement in temps, maybe.

Here we go. I ordered an e6550 (elsewhere) yesterday which arrived today. Stuck it in my P5N-E and got the following results.


My system is - P5N-E, 4x1GB Crucial cheapo 667MHz ram, 380w PSU, 2x500GB HDD's, 8600GT and a few PCI cards.

CP does 3.33GHz on 1.35 volts but will not go any higher however much I increase voltage or slacken timings. I think 475FSB is the limit of my P5N-E with 4 sticks of ram in. Retail cooler used. Not bad for £100.

edited to add-
BIOS used is latest 0608 which recognises CP ok, but for some reason sets default voltage to 1.45v. I dropped this to 1.35 to follow Intel specs.

That Mobo will run at a higher FSB than that, try it with 2x1gig sticks and see what it will push to.

Either the mobo or CPU does not like FSB >475 (even with 2 sticks). I can get into Windows at 495 but not stable. I am happy with 3.3Ghz from a £55 mobo and £100 CPU. 3.5 to 3.6GHz would not make any noticeable difference, other than in benches which mean squat to me.

Have a read through this, its long but should help you

This Mobo does have a few FSB holes but the crunch is at some point you will need to raise the NB Volts as it has an effect on the FSB.
485FSB is good for my E6300
