Can't find out if this motherboard is crossfire compatible.

[GodKoS]

Hi,

My old computer which I built almost 5 years ago is starting to slow down immensely from when I first built it, and I thought it's time for an upgrade, especially with the announcement of the R9 480's a month ago, i'm planning on getting 2, and running them in crossfire, although, I can't seem to find out if the motherboard I've decided to use is X-Fire compatible or not, It's the ASUS H170 I looked on the homepage and couldn't find anything. Here's the amazon link if it helps, Thanks. https://www.amazon.com/DisplayPort-H170-Motherboards-PRO-GAMING/dp/B014F7BQUG/ref=cm_cr_arp_d_product_top?ie=UTF8

It has x16/x4 combination so it'll support crossfire no problem. It's buried on the Asus product page.

It has 2 pci-e 16x slots so you can run crossfire.

 

With crossfire there aren't really limits, if you can get the card properly connected you can use it.

you better read the specs again. 1 x16 slot............. not crossfire capable.

It has an x16 and an x4, both full size. It's crossfire capable. SLI requires x8/x8 minimum, but crossfire does not.

It clearly has 2 x16 slots (one at x16, one at x4, both full length) and the motherboard manufacturer's website states that it supports crossfire.

if you want to run xfire in a 4x slot go ahead. me, I look for a proper motherboard. ( how can a x16 slot be a x16 slot if it states it 4x )?.....( maybe pci-e 3.0 16x and pci-e 4x )....... not many boards are true 16x/16x.......... most are 8x/8x when running 2 cards.

Probably using x16 as "full length" vs something like x1. Not proper, I know, but still.

 The slot is mechanically x16, but only has the electrical connections for x4 use.

And any motherboard has to be certified to run crossfire for them to use crossfire, the same applies to SLI.

Nope they don't need certification, they can ask for certification but they don't have to.

The AMD drivers do exactly 0 checks to see if a motherboard is certified to use it.

 

SLI does indeed do checks like what chipset do you use and do both cards have 8 pci-e lanes.

 

And the second slot is electrically 8x, not 4x, the connector is filled for 50% so it has 8 lanes.

It's something else btw that causes the 4x limit, i'm guessing the chipset or something O_o No idea but it's not the slot itself.
