Best 775 board for clocking and xfire?

ChrisLandin · 31 Jan 2010 at 16:39

Hi all. My friend has asked me to build him a pc using some of his old pc parts and add in 2 5770's in xfire. Now his current board only has space for one gpu so i need a great board for xfire and also to clock his q9650 upto 3.6 gig. He wants to use his current ddr2 ram so the new board has to take ddr2. Cheers.

Use Asrock P45xe is got great OC and supports both xfire and SLI and is cheap as chips the xfire works at 8x and some other boards only work 4x so all in all its great £50 on internet OK!

Hope this helps Wakkie

the P5Q range is good for clocking and there are plenty to choose from.

i use this one http://www.overclockers.co.uk/showproduct.php?prodid=MB-341-AS and it overclocks very well

or even for a smidgen more get the deluxe for the dual gigabit action. Very pleased with mine, but the problem is that you have to compromise between overclockability and xfire performance. X48 supports x16 on both pci-e lanes, but doesn't clock as well as the p45's which only run at x8 in cf

I bought a DFI Lanparty x48 Mobo, and easily got my q6700 up to 3.51 with no problems. Cfire 4870 works really well and is a bonus as it has the 2 x 16 PCIE lanes

agree with the p5q range got my little e6300 upto 3.6 with that board my quads sitting at 3.6 had it at 4ghz not stable though

nothing is better then the gigabytes for overclocking

i can vote for the asus p5q pro board, overclocked great with my old chip, great overclocking for quads vs the x48 chipset and crossfire with 5770's was top notch, it was faster with a [email protected] than my current system in games, god know why lol.

You are going to need a decent P45 board for clocking the Q9650. X38/48 boards may have a pair of 16x pci-e lanes but are not very good at clocking 45nm quads. A pair of 8x lanes on a P45 board will not hold back 5770 crossfire by anything more than a couple of percent at the very most.

even less if the result was made by using DDR3 mobo because there is a sight boost in 3dmark scores over ddr2 mobo's!

Quick question:

Would the X38 Asus Maximus Formula II a good board to hold 5770 in crossfire? As the board has 2* x16 pci-e.
I am running a q6600 on it that will be overclocked when my new cooler comes in.

pastymuncher · 13 Feb 2010 at 13:33

Yes. I had a Asus P5E which is a cut down Maximus Formula and that got my Q6600 to 3.8Ghz. 2x full speed pci-e lanes so crossfire at it's best.
