AMD B350 Motherboards Don’t Support SLI

The age of Ryzen – AMD’s next-generation CPU line – is nearly upon us and, in the meantime, we’re being drip-fed information about processors and associated socket AM4 motherboards. A new report from ComputerBase (via VideoCardz) suggests that the forthcoming AMD B350 motherboards – effectively the budget chipset line – do not support SLI, which is NVIDIA’s multiple-GPU technology, though the boards will support the AMD equivalent, Crossfire, like its bigger siblings. While the news is hardly surprising – anyone set to invest in a pair (or more) of NVIDIA graphics cards are likely to opt for X370 – it’s certainly worth knowing now, since Ryzen processors are already available for pre-order.

On a related issue, VideoCardz posted a statement from Asus regarding socket AM4 memory support:

“I’ve decided to provide some recommendations on DDR4 limitations concerning AM4 currently.

As it stands the AMD code has restricted RAM tuning options which means many RAM kits at launch will not be compatible. This is the same for our competitors also.

What we recommend is the following:

If fully populating a system with 4 DIMMs (2DPC), use memory up to a max of 2400MHz.
If using 1DPC (2 DIMMs) ensure they are installed in A2/B2 and use memory up to max of 3200MHz.

The indication I have received from HQ is that AMD has focused all their efforts on CPU performance so far and will release updated code in 1~2 months when we expect improved DDR4 compatibility and performance.”

AMD’s Ryzen CPUs go on sale on 3^rd March.
