laptop capable of x2 link?

Recommended Posts

I was looking around for laptops to buy that are capable of x2 link on my PE4C v2.1 w/ my GTX 970. I have lots of ivy bridge CPUs so preferred to be 3rd gen intel with HM77 chipset (or any other chipset with an "Extreme" SKU). I had a hard time finding a laptop that is both capable of x2 link  and have extreme SKU. The eGPU candidates list is not as complete as I'd like it to be, so here I am asking anyone who knows of such a combination. ^.^

All I can think of are the Latitude E6530 and E6430. They allow CPU mutliplier overclocking too through IFR mods. For x2 you need to use 2 mPCI-E ports.

 

Is the PE4C stable at 2.0? It detaches at the PE4C's end correct?

I don't know much about PCI 1.0/2.0/3.0 because it has never really been an issue for me, I've used my PE4C on about ~ 10 laptops. I may go for the E6430, but first I'm trying to see if I can do a x2 link on my E5420. I don't have its expresscard attachment and only the mobo though, but would much rather buy that part than a whole new laptop.

For what it's worth, I've got a x2 link running from my Latitude 4310 to my R9 270X through the PE4C v2.1, but it's got a 1st gen i5 and I don't know if the E4000 family supports CPU swapping.

I'd rather not go for anything pre 6-series, but thanks for the info. If by CPU swapping you mean changing CPUs, most if not all laptops, especially 1st gen i-CPUs do 'support' CPU swapping. But the best 1st gen i7 just doesn't cut it with me :\

Don't forget that optimus PCIe data compression is only available on x1 link.

That's only for dx9 though, right? I don't typically play games that are dx9, especially more so since dota 2 is now fully dx11. But thanks for the tip.

No its everything. If I remember right optimus x1 links usually matched or outpermed x2 links in dx9 titles, but in dx10 and dx11 x2 almost always beats optimus x1, but optimus would still be a major improvement over pure x1.
