I agree. Would be a welcome upgrade from my gracefully aging ECS RS485M-M + 5600+ X2 + 8800GT. I NEED a quad core and DDR3!

yea with a 4890, though I'm eagerly waiting for ATI's directx11 cards

Does the BIOS have to have the ECC 'Hybrid' option in order to have a stable unlocking of 4 cores?.

My BIOS has the ACC 'AUTO' function and can unlock by 550 to 4 cores, but they are not stable under stress testing, so i have to go back to 2 cores...

Would the 'Hybrid' mode make any difference to their stability?..

Basically, Gigabyte is not allowed to ship the motherboard that will unlock cores out the box. It uses its dual BIOS function to hide the Hybrid BIOS in the second physical BIOS chip. The benefit of Gigabyte's Hybrid BIOS is that you can see if the cores unlock WITHOUT having to reboot, however, it does nothing more to stabilise your cores - you either have to add more voltage or buy a new CPU.

How do i gain access to the 2nd BIOS with the Hybrid option?.....

Da_Rude_Baboon 4th August 2009, 16:10

Why don't you include the power consumption in hibernation and standby?

It's simply by selection the BIOS option shown: changing the value from Standard to Hybrid within the BIOS does this.

We never do.

Nice review. Wish manufacturers would try not to put sata ports behind the second expansion slot though, i have several motherboards (both Intel and AMD) that struggle to accommodate a Sapphire dual slot 4870 card when 4 or 5 sata connectors are attached.

Still not good enough IMO. Draws too much power, heatsink too big, gets too hot, etc.

I cant wait for P55 that looks to me like it's going to be awesome.

That's with a tri-core CPU mind. Drop in a 45W CPU or 45nm Phenom II dual core and that'll drop. Use a more efficient low power PSU and it'll drop. Use slower 1,066MHz 1.5V DDR3, it'll drop. Use a 2.5" SSD and it will drop. Underclock the GPU! There are lots of ways to optimise. The chipsets are made with a 55nm process - there's literally not much more you can do.

scan seem to have an AM2+ DDR2 785g board... (which i guess would just be a 780g with uvd 2.0?)

Bindibadgi 4th August 2009, 22:18

No it's 785G, but just with an AM2+ socket - the chipset just needs to support the faster HyperTransport 3.1 spec for the AM3+ socket.

At least the sata ports are in the right place on the Asus board :)

This will be £80 at Scan soon.

£12 more than I was quoted :(

Yes, it uses DDR2 memory!

No, no it doesn't. It's DDR3.

There is a DDR2 version, but you have to look for AM2+ 785G boards like: http://www.scan.co.uk/Products/Asus-M4A785D-M-PRO

Just out of interest does anyone know what relation the *new* Gigabyte GA-MA785GT-UD3H available on CCL is to this board? Or at least what the differences is are?

Sorry, its ATX vs mATX on the UD2H. My bad

Oh crap. How did I mess that up? I realized that and yet I wrote DDR2. Yikes. Brainfart. I'm sorry. Really, really sorry. :(

I don't like embarrassing myself in front of moderators.
