Is it Truly necessary to upgrade 9260 mobo??

so i've been talkin to different ppl who say they've put in an 8800 and Q9x50 CPUs with the old motherboard and that its no problem. I have the mobo back from AUg '07. And im about to spend over 250 to swap mobos to support these new pieces... but IS IT NECESSARY? i understand it may void warranties and stuff. But is there any SERIOUS reason that I should just put in the 8800 or q9550.. Will it not physically support it? Has any1 tested doing this?

 

Considering the m570ru didn't need it since zfactor proved it, I really wouldn't be surprised if the d901c doesn't need it either.

 

I'm really curious about this guys... If any1 can give me hard proof.. by showing an old mobo with these parts... Plus maybe if Donald or Justin want to hop in and say why it was done and wat they think of doing this (as they work with these systems)... I'm rele contemplating not changing the mobo. I would LOVE some input here... as it would lead me to saved money... and any help to some repz

I do know it had to do with thermal requirements i think... but only 1 or 2 components were probably changed on the whole motherboard if any...

 

No need IMHO as the changes aren't significant.Add the parts that you want and if it don't work,upgrade.My 2 cents.

 

Did any of the people who put 8800s and Q9x50s into their NP9260 systems have dual 8800s operating in SLi?

The big sticking point, and the reason for the motherboard upgrade, had to do with SLi, not simply with just using the 8800. As I recall, the most that the forum was able to get out of those-in-the-know was that the upgrade process involved soldering a new IC of some sort onto the pre-8800 motherboard, and that it was related to the fact that the display unit in the 9260 was an EDID-less display, as is the industry standard for notebooks, and that NVidia had taken the unusual step of making most of the GPU card in-house and, in particular, not providing support for EDID-less displays (EDID refers to the basic data about the display unit's capabilities, and can either be provided by the unit itself - the more expensive option - or from the motherboard either via a BIOS extension or a separate expansion ROM).

Basically, my supposition is that the soldering I referred to involved inserting an IC onto the motherboard between the GPUs and the display unit that would by itself provide the necessary EDID data, so that, from the perspective of the GPUs, it would look just as if the display unit was, in fact, providing its own EDID data.

So, I would speculate that it may be possible to run a single 8800 on a pre-9262 motherboard without too many problems, but that you will not be able to run 2 8800s in SLi without the motherboard upgrade.

 

well im hopefully going to run two 9800s on this beast... so jumping two generations with no new mobo is probably a nogo...

 

That would be my guess, although you might pm Paladin44 or Justin@xoticpc to see if they can give any better of an answer in private.
