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 ?

Gonna retest the Blades on an X58 board this afternoon. I really hope they are still in working condition, but ... I'm not postive as the boot-up also reported 2GB at one time :(

ow 2 sticks down now ? you really know how to make my day

Switched to bios F5c and running two sticks (#1 and #2) again. No issues so far.

Weird :-/

#1 and #2 are just fine, check screenshot. Now testing #3 ... but looks :(

UD6 breaks i5 750 world record :-)

Wich was owned by a uD6 in the first place :D Good job!

Ok. :p

The important thing I that I beat my own record :D

Exactly :p

First Congratz

2) with looser tmings does't it go further ?
3) The Game has changed !
4) don't tell DiegisOn :p

Didn't bother, quite frankly :p

Ola ola :D Don't tell Diegis0n what? "The game has changed"? :-/

It has? :p

Maybe it's my spliff pulling a trick on me, but i sure as hell am confused :D

PS: been playing with a 750 myself the past hours on a P55M UD2.
Though it's the cheapest mobo out there and doesn't have fancy options, i got to 4.4ghz in a flash.
That is also where i had to stop, on a stock cooler it's not that willing :p

I forgot :

That's around 210 BCLK right? It's not the cooling, it's the silicon of your cpu

Yes it is, what do you mean "it's the silicon" :-p

most of the lynnfield chips max out at around 205-210 bclk on air cooling

need more cold, most love single stage for max bclk testing ;).

Even single stage doesn't max out the chips; you need actual LN2 to max out any lynnfield.

Or a crappy cascade of course :p

it still do's the stuff for needed testing ;).
still cheaper on year base then LN2 :p, when game rig is done il rebench.

It's a shame i don't have a crappy cascade, i'de be glad :D

:D

Nice WR :) Eff's improved compared to the GD80!

ln2 again ?

Yeap :)

Also improved cpu-z again

If I'm not mistaken: highest CPU-Z for retail lynnfield

wtf ?
