adding 2nd 780m to m18xR1 partlist questions

fan - 0XHW5W- for RH GPU - this fan is on the left side if you're looking at the underside of laptop with rear panel removed
sli cable - check
100w RH heatsink w/pads- question, see below
780m alienware green pcb used - check

am i missing anything?

does anyone know if RH heatsink
Y3WC7 is measurably different from Y48TK? because one comes with thermal pads and id rather not get the one w/o pads if there is no difference

 

See what I posted here: http://forum.notebookreview.com/threads/upgrade-860m-sli-gpus.775493/#post-9996062

Y48TK is the correct heat sink to use and it comes with thermal pads. The price is also shown.

 

what website is that?

edit: found a cheap one on ebay

 

would a blue PCB clevo 780m SLI normally with a green PCB dell 780m?

 

ok just bought everything....card, heatsink, fan, pads, sli cable

total came out to about 550 i think? maybe even less

 

As far as I heard Clevo 780M can only work one at a time in M18xR1 but im not 100% sure.

 

No, thankfully, that is not correct. I have both Dell and Clevo 780M cards. My M18xR1 absolutely loves 780M SLI using Clevo GPUs. When I was trying to get 980M SLI working in my M18xR2, I was running my Clevo 780M SLI setup in the R1 and it was flawless. Clevo NVIDIA MXM cards have always worked well in the M18xR1 and M18xR2, single or SLI. They even use the same vBIOS as Alienware 780M cards.

It may have been MSI GPUs rather than Clevo. If I remember correctly, until Maxwell, MSI MXM cards did not even have an SLI connector on the PCB and they had some compatibility problems installed in non-MSI laptops.

 

Ah then I read wrong information, you are surely right

When I wanted to buy 780M I saw some ebay auction that seller told me Clevo 780M can only work one at a time in SLI laptop but he could be an idiot ;D

 

I could be wrong Mr. Fox, but I think the op is asking whether his R1 nvidia green pcb 780m will sli with a secondary blue pcb card.

 

Maybe so. I'm 99.9% sure that will work OK, but I've never had a reason to try it. Other than the brand of vRAM sometimes being different, they are basically identical except for PCB color.

 

Mr Fox, MSI didn't even have an SLI laptop till the GT80 ... Makes perfect sense for them not to have the SLI connectors since it saves a few bucks with SLI license fee and connector cost.. Makes no sense for us enthusiasts though

 

I think so @TomJGX. I have never had any interest in MSI laptops, so I have not put forth any kind of effort to follow their development. I know, based on what I have read and seen in photographs, that their proprietary GPUs (like goofy ASUS laptop video cards) have been worthless as upgrades on other brands for at least several generations. I still have zero interest in their laptops, but from what I can gather reading random posts and viewing photos in forums, it wasn't until Maxwell that MSI finally joined the ranks of "normal" with respect to MXM GPUs.

 

i went with a green Dell pcb just to stay on the safe side and avoid possible problems from SLI'ing a clevo with a dell card

very psyched and looking forward to the SLI setup....a 780m is quite easily bottlenecked even running at the boost 850mhz as i have come to find out
