Howdy all,

It's been made clear that the Asus Z490 boards ONLY support PCIe 4.0 on the first full PCIe x16 slot.

My question is:

Does the Formula board actually support/use the addition 4 PCIe lanes that the 11th Gen CPUs have? (20 lanes vs 16 lanes)


I'm hoping it does, possibly to the rear m.2_3 slot, when an 11th gen CPU is installed. Even if its only pcie3, it would be better than nothing.


thanks!

I noticed even after tweaking, both M.2 drives works way, way slower than before and there are no changes in BIOS M.2 section (BIOS 2004 version)...
One of my M.2 is a corsair mp510 ver 3.0, another one is a new Samsung m.2 PCIe 4.0, both works super slow, like about 800mb/s, on my 10700k all works great, about 3.2k mb/s.

Checked also RAM speed, with my 4x 3200 CL16 dominators, effective speed by almost all benchmarks incl. 3DMARK and UserBenchmark are below expectations, 15-20% slower in a RAM section...

One benefit is only PCIe 4.0 support for GPU, but in general "just after upgrading" my system is slower than before.

Will drop another screen after putting back in my 10700k.

As I promised, tested on my 10700k.

I would love to upgrade later after returning my 11700k but please ASUS, make a good BIOS update.

We pay really A LOT for top tier motherboards and we are not able to use it with next generation CPU, it's insane how things are changing here...
Can understand, lower tier mobo will have some limitations but Formula ;c
