XFX 650i Ultra Socket 775 Motherboard

Overclocking

Overclocking

Overclocking was performed through the BIOS, as all good 24/7 overclocking should be done. After seeing the limited options in the BIOS I did not have too high hopes for the XFX.

Low Voltage Overclocking

I usually start off by overclocking using low voltages. I chose 1.33v to get started with on the XFX and set away to see what I could achieve. Before I show you the results I want to make it clear that the board was particularly hard to get restarted when overclocking and it got rather frustrating continually pressing the on + restart switch if there was a failed overclock, or even if the OC was OK but the board chose not to respond.

A surprising result of 3350MHz at low volts, a pretty nice OC and fully stable.

Overclocking - Highest Possible Stable on Air

For this test I stopped when I got concerned that the temperature rose too high. This overclock was performed on air using a Scythe Infinity. I stopped when the CPU started getting around 65-70°C. For this overclock I had to use 1.60v (the highest on the XFX) which is not always to be recommended for those who are faint of heart! Let's see how we get on here.

xfx 650i ultra 3700 max oc

Again a respectable 3700MHz at 1.6v, the XFX was beginning to look better and better value for money.

Max FSB

Here the XFX let me down a bit, which I think was mainly an issue with the NorthBridge voltage selection being too low.

xfx 650i ultra max fsb 425

425MHz isn't too bad, but it isn't exactly great either. As I said above the board is hard to get to recover from a bad overclock and especially so at this point, it took a good few reboots and CMOS resets at one point to get a boot out of the motherboard.

As always with overclocking the chip and the chipset will vary in overclocking potential, but this at least gives you some idea of how you may get on.

"XFX are well known for producing high-quality, high-speed graphics cards. Now they're stepping it up and getting into main-boards. I take a look at the 650i Ultra and see if they do as good a job"

Thats pretty cool, i went for evga 680i though, by the way your link to the forums on the review is dead.

When you review stuff do you just get given it to test?

Did you get my pm?

Thanks

Nice review, glad you pointed out the green! My 15quid Epox board is green

Cool review

I find it wierd that people are talking about mobo's (or hardware in general) when they mention 'colour schemes' etc

Reminds me of this thread

Not like the old days

QT. I remember marveling at one of Abits first mobo's that used a brownish PCB and thinking how cool that was compared to the green ones. Of course the PCI slots were white and the AGP,RAM and PATA slots black.

it's the same 650i Ultra nVidia reference mobo as eVga (& no doubt others) also provide.

bit surprised that it isn't significantly cheaper than a 650i SLI solution though.

Ye I was slightly surprised at that too

Not a BAD mobo, just nothing special
