Most people are only interested in 2 way SLI as a future upgrade, and ASRock does 2-way + an x4 M.2. In regards to the 5820K, MSI has "4 (x16/x8/x0/x4*, x8/x8/x8/x4*) *Forces M.2 to PCIe 2.0 x2" What this means is that the fourth slot is shared between M.2 and "PCIe x16 slot 4" I believe MSI's entire X99 range is made the same way, apart from the boards that have a PCIe 48-lane switch. has 2nd-tier (price-range) X99 motherboards with Gigabyte, ASRock and MSI compared, and it has the PCIe stuff you're looking for.

The Professional happens to have a $40 rebate plus $85 DDR4 combo discount, making this a ~$220 proposition for this board.

The lowest price board I could find that can do this is the ASRock x99 Fatal1ty Pro or OC Formula, both in the $340-350 price range. So I think I'm looking for a board that can do both a (1) dual SLI x16/x0/x8 + x4 M.2 or (2) 3-way SLI x8/x8/x8 +x4 M.2, all at just above $200. Shorter term would more realistically be air-cooled 2-way, and my understanding is the MSI is not the best for 2-way air cooled due to the slot spacing.

Long term goal is water-cooled 3-way x8 + PCIe x4 M.2. That about summarizes it - thanks! I'm looking at a 5820k based rig. You'll see another MSI board in a review still pending its publishing date. Gigabyte has the USB 3.0 header blocked by a fourth card, MSI has the three cards + PCIe x4 M.2 +USB 3.0 configuration nailed (if you care about PCIe x4 M.2). The good news for those whose hardware choices are unaffected is that-unlike its long-divorced partner-ASRock didn’t screw up the X99 Extreme6/ac’s PCIe 2.0 slots.ġ5153170 said:Right now Gigabyte has the best lane configuration and slot spacing four four cards, MSI has the best lane configuration and slot spacing for three.


The Core i7-5820K processor breaks three-way SLI capability, and a PCIe-based M.2 drive disables that slot entirely. At any rate, the X99 Extreme6/ac bears the same three-way SLI caveats as the recently-reviewed Asus X99 Pro. Or perhaps the engineers just wanted to save a few dollars in PCIe pathway switches. In unfortunate mimicry of its closest competitor, ASRock doesn’t split the first slot into x8 mode, even when the lanes are needed elsewhere. 3 (x16/x16/x8) SLI x3, CrossFire x3 M.2 disables x8 slotģ (x16/x8/x4) SLI x2, CrossFire x3 M.2 disables x4 slot
