ASRock X299 OC FORMULA LGA 2066 Intel X299 SATA 6Gb/s USB 3.1 ATX Intel Motherboard

Pros: The first one to review? With the help of Asrock X299 OCF, the desktop performance beast 7980XE, 18 cores, 36 threads, the memory can get up to 4400+ quad channel, and the read bandwidth can get up to 130GB/S, the CineBench R15 can reach to 4600+ score by water cooler. And I can stress Prime95 v29.3 64bit FMA3 by core 4.8@1.229v and mesh 3.0@0.90v as well quad channel memory 4200c16@1.44v for one hour by using 7900X.

Cons: I like this motherboard.

Overall Review: If you need best productivity, I strongly recommend the motherboard above with high performance price ratio.

Pros: Great features and many pci express slots for multiple cards. The memory overclock works great for DDR4-4000

Cons: None so far

Pros: Easy setup, nice overclocking capabilities, multiple pcie lanes are very nice, doesn't look too flashy either

Cons: none so far

Pros: The thing that makes this motherboard different from all other X299 is that you can run five PCI-E slots at X8 plus the X4 slot plus the X1 slot concurrently (if you have a 44-lane i9 CPU). As of April 2018 this seems to be unique to this motherboard. I do not need x16 GPU support so this ideal for me. Second thing that is somewhat unique: In addition to all 7 PCI-E slots running at that bandwidth, you can also use all 8 SATA connectors plus two M.2 NVMe disks concurrently. Some motherboards share lanes between SATA, M.2, and PCIE but this one does not. Make sure your M.2 is NVMe not SATA (why wouldn't you...). Ubuntu Linux Server 18.04 seems to have discovered all of my devices as expected.

Cons: 1) It only has four DDR4 RAM slots, other X299 have 8, so max RAM is 64GB. 2) I think the RGB stuff is dumb. 3) There is only one USB 3.1 Gen 1 header on the motherboard and most PC cases expect two. This motherboard offers a USB-C header which might be great in the future but currently I cannot find a cable to match the header. 4) Took me forever to figure out how to set the clock in the BIOS - hint: not available AFAIK from "advanced mode". 5) BIOS is constantly shuffling my carefully-chosen boot order based on devices it finds. I know that's a Feature but I wish I could lock it down.

Overall Review: I paired this with qty (2) N82E16820215181 from the QVL which worked great. [ADATA XPG GAMMIX D10 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Desktop Memory Model AX4U3000316G16-DBG)]. Also I bought two of the 2018 WD Black 3D NVMe M.2 cards which seem to be compatible.

Pros: If you want to get the most from your expensive X299 processor without going insane trying to figure out overclocking options, this is the board for you. Also the stability, ease of getting it up and running, and overall impression are excellent. The ease of use compared to other manufacturers was key for me, as ASROCK seems to have a better handle on the tsunami of new processors coming out. I have friends who are pulling their hair out working with MBs from the other manufacturers. ASROCK seems to be getting better as they are fading.

Cons: Not really a con, but understand that this MB is missing a few of the features that gaming boards usually have, like lots and lots of pretty leds and 10gbps networking.

Overall Review: I wrote this review for the ASROCK review rebate program, but I would have written the exact review without it.

Pros: This was the first board with a good VRM and heatsink on X299 platform. I've never had a single issue with either of my two boards and both overclock extremely well with KBL-X and SKL-X.

Cons: M.2 ports are both through the PCH which is great for KBL-X but terrible for SKL-X. Second BIOS requires jumper instead of switch like other brands.

Overall Review: Best board you can get with ATX form factor for X299.

Pros: 100% stable running Intel i9 9980xe with zero , 0 , nada problems and 64GB DDR4 ram 3600Mhz butter smooth. Well designed and proper heatsinks on this mobo it runs cool. Lots of features , excellent efficiency , awesome sound and Intel Nic , many pci express to suit anyone needs , 4 way sli or 4x crossfire x no problems. Great software support. Awesome customer support. Highly recommended !

Cons: None.

Overall Review: Do yourself a favor and buy this motherboard instead of spending lots and lots of money on other brands.

Pros: -High end quality components -Large VRM heatsink -Best bios layout in the industry -Has "retry" button which previous generation OCF boards don't

Cons: None really, see other thoughts

Overall Review: I use this board for its specific intended purpose of achieving the highest possible overclocks. Handles 4c to 18c and everything in between with ease. Memory OC is great 4133+ 12-11-11-28 is possible with kaby-x cpu. My only minor complaint would be it doesn't have dual 8pin cpu power. However this really is a non issue as I pushed 7980xe to 5.6g+ on ln2 pulling over 1000w load and the 8+4pin had no issues at all.
