memory needs to TRAIN when you plug it in and boot. let it keep trying.
try all different combinations of placement in memory slots, but always match slot to get dual channel

i tried 6 different combinations, ramping up from one stick, letting the pc train the memory then add another stick reboot etc until it trained in all sticks. trying pairs in diff slots also

google ram training

make sure you dont have any bios settings manually set for ram, best to load factory defaults

Rock_Solid, do you know if the Z77 Extreme4's PCIE bus actually supports bifurcation or not?

I'd consider getting something like this if it'd support more than 1 card:

https://www.newegg.com/Product/Product.aspx?Item=N82E16815548004

This spec has always confused me a little:

2 x PCI Express 3.0 x16 slots (PCIE2/PCIE3: single at x16 (PCIE2) / x8 (PCIE3) or dual at x8/x8 mode)

Little late but thanks rock, grabbed a bargain myself too :)

Seems I found on the exreme6 slot PCIE5 PCI Express 2.0 x16 slot is only x4, but seems to drop in performance on the NVMe I am using...

I have to use slot PCIE4 which then halves the lanes on PCIE2 down to x8, then I get the full throughput that the NVMe can support.

From what I reading though, and the performance tests I have done on my 1060 6gb in PCIE2, there is not really much loss!

Does anything actually use x16! to the max...

Never used to boot, only as 4th drive... I boot already from another SSD, which takes 5 seconds, so not really sure if 1 more second is going to kill me Wink

Hey Thunder,

I feel your pain with that one... it could do with a little better grammar!

PCIE2 = x16 Slot = x16 Capability
PCIE3 = x16 Slot = x8 Capability

If you use these slots in single mode, you get their capability.

If you use these slots together (Dual), PCIE2 = x8, PCIE3 = x8, this does not matter what is in the slot, GPU, NIC, NMVe (with adapter)... you will only get x8.
