Crossfire on NF4- hacked yet?

[Kil4Thril]

As above. Has anyone figured out how to do dual ATI's on an NF4 board? Or, is there some hardware limitation? I'm guessing it's a driver thing, but I don't know shit about it. Besides, anything would be better than what I'm running currently

maybe this gen of Xfire (X850) is not worth hacking? maybe they waiting for the X1k Xfire to show up then do some work

Everything else in your sig rocks. It's time for a VGA adapter upgrade man

i dont see why it wouldnt work as it is now. not like theres any interaction between the chipset and the video cards?

 

[morningreis]

It is supposed to be possible with a simple BIOS flash.

The only requirement AFAIK is that there be two PCIE x16 slots and an SLI chipset. I guess other than that it should work fine.

Rather than start a new thread, wondering this myself.

I want to buy a motherboard that maybe crossfire/sli (depending on what I stick with) ready

Anyone do a crossfire on an SLI motherboard

i was wondering this as well, but doesnt crossfire need an ATI northbridge?

Its suppose to, but if it works on current intel chipsets I dont see why it wouldnt work on Nvidia's. Obviously they want you to buy their chipset though....

 

[Andross182]

damn i would love to not have to upgrade my MB and switch back to the red team, do you know if crossfire splits it to 2 8x slots or does it utilize the dual 16x ones?

I'm pretty sure it needed a specifically coded southbridge for CrossFire to work.

really? hmmm i wonder why then on the egg you there are 2 northbridge chips...radeon xpress 200 and radeon xpress 200 crossfire???

i would assume its simlar to the NF4U/NF4SLI differences...

well yeah but those differences have to do with the northbridge chip and not the southbridge (the mod trick)

I heard at one point that Intel is trying to get licenses from nvidia and ati so that they could incorporate sli/crossfire into their own chipsets

it would be nice if nvidia and ati would just play nice and make their chipsets compatible with both crossfire and sli...cuz i think it would a huge benefit to the customer.

the NF3/4 chipset are a one chip solution, there is no southbridge per se because the functions are incorporated into the the NB

ya know what sucks about that? intel boards dont allow overclocking...

Yea but if Abit, Asus etc use their CHIPSETs, they allow for alot of overclockin!

The Vodoo PC CEO in his blog said they were playing around with such a hack recently....

Here’s the ultimate test – when ATi finally releases their Crossfire edition x1800 board I can’t wait to test it with an nForce4 vs the latest ATi chipset. Everyone knows Crossfire works with nForce4, and I think we’ll see the difference a chipset makes. I think the fact that ATi designed it to work independently of the chipset is the best feature of Crossfire. We’re currently evaluating Crossfire on nForce4 using 850XT’s (ATi paid us a visit last week), it should be interesting once we get some of the better motherboards in with ATi chipsets.
