Gigabyte X99-SLI Motherboard Review

Posted July 28, 2015 by Kenny in CPU & Motherboards


Price at time of Review: $240.99 on Newegg.com


Simplistic Aesthetics, Stable performance, Great Value for the money


Memory Overclocking stability pass 3000MHz.
Gigabyte priced this competitively and gives other manufactures a run for there money in the same arena. For a board that can support M.2 SATA, SATA Express, Quad/Triple/Dual SLI or Crossfire, and DDR4 memory of up to 3000MHz out of the box, this is a bargain.

The Gigabyte X99-SLI motherboard was a nice revision to see. As we had mentioned early on in the review, the X99-SLI looked more like a revision to Gigabyte’s older X99-UD4 model. While the boards were not exactly alike, they both shared some very close characteristics. Perhaps Gigabyte has developed too many of these revisions. It can get confusing to consumers when trying to select the right motherboard for their application. But this can also be a great aspect of things since you now have more than one option from the same manufacturer. It can be a win win for both Gigabyte and its consumers depending on how you look at it.

Now that we got that out of the way… The Gigabyte X99-SLI much like the X99-UD4 and the UD3P motherboards, doesn’t have all the fanciest aesthetics we find with the higher end boards. However, this doesn’t take away from its aesthetics. The matte black PCB with a hint of gold/yellow gives it the contrast it needs. The full sized ATX motherboard was also laid out well just like we saw with the Gigabyte X99-UD4 and its UD3P motherboards we previously tested.

Digging a little deeper with what you get from the Gigabyte X99-SLI, the board is priced great for starters… at $240.99 at the time of the review on newegg.com, it comes with great features and is a well rounded motherboard in the performance arena. Pair this board with the right chip and memory, and we have ourselves a great set up. Since the motherboard can handle multiple graphics card from 2, 3 and even 4way SLI and Crossfire you can build a beefy gaming system or even a workstation to do some rendering work. Intel’s 5930K and 5820K would be the best suitable processors for the Gigabyte X99-SLI. Remember, keep in mind that the 5820K does have fewer lanes available. If you do plan on getting the 5820K, you can’t run more then 3 graphics card with the X99-SLI.



When it comes to the software package, Gigabyte hasn’t veered far from its design and layout since the review of the X99-UD4 and UD3P. With the carry-over of the now well matured Gigabyte App Center, they did a great job at including an abundant variety. The software package that was available with the motherboard gives users something to appreciate and shows Gigabyte has been working hard in this sector to continue to improve.

In the last review of the X99-UD3-P we pointed out some nit picks which included a slow post time from power on to the BIOS. It looks like they have resolved this issue with the X99-SLI motherboard. This is greatly appreciated and shows that Gigabyte is still hard at work improving its own products. So bravo to them!

All in all, we feel that Gigabyte did a good job on the X99-SLI motherboard and with its price, it puts it right in competition of MSI’s X99-SLI motherboard. The X99-SLI also adds a bit of value if you really liked the X99-UD3P from Gigabyte. You get the additional memory slots to run 2 sets of quad channel memory adding to more memory capacity. For only $40 bucks more, the Gigabyte X99-SLI is a winner over the older UD3P. But this can also be a bad thing as Gigabyte is offering too many of the same features on motherboards all within a $50 price bracket. They can ultimately kill their own offering with so many of the same boards.

Now, taking into consideration the price of the board at $240.99 on Newegg.com, we feel that Gigabyte priced this competitively and gives other manufacturers a run for their money in the same arena. For a board that can support M.2 SATA, SATA Express, Quad/Triple/Dual SLI or Crossfire, and DDR4 memory of up to 3000MHz out of the box, this is a bargain. We give the Gigabyte X99-SLI motherboard the PureOverclock Great Hardware Award.

great hardware
