Heh, maybe they finally made a board that's at least by specs is able to compete with DFI (on paper, the Vdimm is looking nice - although I didn't find it mentioned anywhere on Abit's website)? Would be nice, actually, otherwise I'm already getting tired of DFI nF4 boards all over in people's sigs everywhere

finaly, abit back in bussiness.... 3.55v is great, it´s much better then the v. that's fatal1ty non/sli..
i´m curiose about his power =====»»» OC

[HKPolice]

I don't like it. Sure it can go upto 3.55 vdimm which means it's running off the 5v rail, so you can't do the 3.3vrail = vdimm mod = less stable vdimm and overheating ram mosfet.

Also, the dimm slots themselves are so close together, with few surface mount capacitors/resistors between each other. DFI boards have more, and have always overclocked the highest.

Edit: Also, the 16x PCIe slots are too close together, only the Asus SLI board has it setup perfectly

The only good thing about this board is the OTES, but then again I bet the crappy fans will get loud after a few months.

The only reason for DFI making the 3.3/5V switch is because the nF4 series uses a linear VRM for Vddr. That means that a lot of heat is being dissipated on the MOSFETs in order to lower the voltage from 3.3V/5V rail to whatever voltage is the RAM working at.

Abit's Vddr uses a switching (PWM) VRM... like the one used for Vcore. It's quite efficent, and DOES NOT dissipate a lot of heat... nowhere near of what DFI's VRM is dissipating. The only downside is that the voltage is not as "clean" as that of the DFI (switching VRMs need a lot of caps to provide non oscilating voltage). But I'm sure there won't be such problems with the AN8 Fatal1ty SLi board... you can see a lot of caps near the Vddr VRM.

But I doubt it can be a serious contestant... the main problem is the BIOS. It lacks a lot of tweaking options for DRAM.

yeah.. i just hope the voltage are stable and bootable.... for .... winbond bh5/ bh6/ UTT user

[jrw]

I would so much like to see Abit back in the game!

Abit, DFI and Sapphire in the mix

[GoodOmens]

I too would like to see abit back in the game.

[HKPolice]

Ya I'd like to see them back in business too, but I have serious doubts, especially since Oskar Wu left Abit and joined DFI.

I have hope for Abit because at least they USED to make great OCing boards. Sapphire I have no hope at all since they've never even made a mobo before.

[WeStSiDePLaYa]

doesnt look nice to me, poor cmos battery placement, bios chip is poor, ram dimm spacing is bad, will overheat middle sticks very easy,

ill admit though the placement of the ide ports and sata ports is good.

Ya agreed.. i hope the low budget AN8 Ultra(non sli) would have same features as this board.

Anyway the voltage option looks serious at 0.05V increasement
Adjustable VTT voltage & new VTT divider ddr/2

Hope they back in game

the ABIT AN8 Fatal1ty SLI

Vdimm : 2.55V - 3.55V
Vtt voltage: 1.25v ~ 1.75v and DDR/2

[cupra]

thats look like a nice board, he can join the dfi 939 boards and be one of the best bords for that socket, but i think that we should wait for a benchmark results.
i have a feeling thet the dfi 939 will be like inspiration for all the manufacturers so i will not be surprise if asus/epox and more will release boards that can give us high voltage.

thanks for the news tictac

find another place to put NB, not UNDER the freekin' GPU!!!!!

here is the DFI:


I like the Layout of the Abit Better. Look the Power circuit on the DFI is infront of the CPU socket, and in all the systems I build the Case air flow go's from front to back.
I Like the Otus crappy fans or not it removes the heat generated around the CPU socket.

The NB looks like thay are in the same place., and Who Uses 4 dimms running 5,2,2,2.0 @ 3.5V??

The supplied ram air cooler will work on the average Ram overclocking using 4 dimms.

I like DFI I have had about 10 DFI boards, the Best boards I have owned. But If Abit can come out with like Volytage options and some Decent forum support ,The layout of the board seems fine.

[crotale]

I wonder what will happen to the CMOS battery when running when running sub zero...

[situman]

I wonder how many people actually cools their cpu at aub-zero temps.

[Vincentvega18]

I wonder how many people actually cools their cpu at aub-zero temps.

Well if your going to say that, why not say how many people are going to use 3.55vdimm, sli etc. Not things that everyone uses, but a lot of people here do.

Enough

[[XC] leviathan18]

i dont like the otes because use small fans at high rpm and eventually they will go louder or die so i dont like that....

the layout dimms are too close if you have vx they are going to run quite high...

[situman]

Anyone else think ABit is getting cheap with regards to their caps? I know they are still Rubycon, but they look damn small compared to the ones on the IC7. I used one on my friend's computer and I was shocked to see how small the components are. 110 plus vat, how much is that in US dollars? No need for SLI, I'm an ATI guy. ANyone know when the Ultra is coming out?? Does this mean the regular AN8 and AN8 Fatality nonSLI will get discontinued?
