Gigabyte GA-P55-UD6
 

Recieved this a couple of days ago; will start testing after I've wrapped up the Core i5 review (should be in one-two days).

First results I find in OC forums make me have high expectations!

Looking forward to this board compared with Asus brand new toy (better get Milan on the phone :p)

More pictures in the upcoming review of this board!

Wow, this board seems to be really fast :eek:

Okay, in contrary to the GD80 board, I can increase the PCI-e frequency quite a lot on this board. Now booting 113MHz and still going up

GD80 doesn't do 103 stable

145MHz now :-/

I've been playing with the P55-UD6 on air and single stage these last couple of days and I found a whole new appreciation for the GD80 board :).

As for the UD6:

- Memory bandwidth performance is excellent; very easy to reach high numbers without actually pushing the memory.
- Bios is absolutely fantastic in terms of lay-out
- Board feels smooth overall (<-> gd80), but that's a very subjective opinion. Don't know what it is, just feels smooth
- Hits 150MHz PCI-e with small increase in voltage - too bad not much performance increase
- On air it clocks pretty much the same as the GD80

- On phase I can run 230x20 as stable as on the GD80, but with the GD80 I can push to 233MHz 01 stable whereas it's nearly impossible with the UD6. Reason underneath.
- A lot of issues with vcore/vtt setting. I boot 1.50/1.50 or 1.518/1.52V, but anything over that just doesn't work ... on the MSI I can't go over 1.54V VTT either, but I can push a little bit harder on the Vcore on single stage, hence why I can bench a tad higher.

In any case, thanks to the better memory and uncore performance I've been able to increase my 01 score with 1200 points using less mhz.

That's incredible... I am curious though, just to check are you sure that the BIOS setting has a real effect on the PCIe freq? I've seen early BIOS's offer settings that didn't actually change anything, and such a gain would be astonishing!

Next question would be if overclocking the PCIe freq changes the DMI freq, since it's really a PCIe 2.0 4x link?

I'll digg into that today, but it seems that there's actually a frequency change. For 150MHz I need to bump up the voltage because it's not stable at stock volts; that would indicate there's a change.

Blades working condition ? those results are with the Plat's I suppose ?
