#31 RE: [OFFER] Asus P9X79-E WS (1704) Bios mod for NVMe support by Dewizzer 02.12.2020 19:16

Hi MiG174, we owe you more than a beer. Anyway, I just ordered the card that he suggested, can I make a bootable raid 0 with two nvme on our mb? And which slot is best for this, the x8 wired to the cpu or any x16? What I mean is, will my drives show up in the hardware RST raid menu? I noticed that what I wanted to do didn't work for one guy, that is a raid 0 on slot 4.

no, never. can only soft raid in OS

If it's just soft raid, we could even use one adapter for each nvme drive, what's the point of an array card other than save space on the pcie slots?

Hi! Could you tell me how is your experience with that card? I've been using Asus Hyper M.2 X16 3.0 on P9X79-E WS with bifurcated PCIe 8x into 4x4x, but I have problem with stability of second drive. It is always recognized as PCIe x2 instead of x4 - even if I swap drives between slots, always drive in second slot is x2 and in first is proper x4. Additionally, sometimes access to x2 drive crashes. If OS drive is in slot two, then I have full BSOD, if not, then only software i.e. game crashes and OS can not open any file from the drive.

It looks like some power issue or link negotiation problem.

Do you have any problems with your card? I'm considering buying it. I use current BIOS from MiG174 (Thanks BTW!).

Edit: I am adding some pictures from HWiNFO for overview:

Hi MiG174 !

First of all my congratulation for your astonishing work !!!

I have a P9X79E-WS with 2687W V2 and have GSKILLL 2133 64GB ddr3, an extremely performant couple till now. I casually discovered this blog and, after some weeks of evaluations, I succeded in flashing my board achieving totally new performance (I wrote lots of C/FORTRAN codes for radar image data processing).
OS like RH7 and Centos have changed totally their behaviour.

Nevertheless I was not able to make working NvME boards with more NvME devices (an ASROCK Hyper x4 four slots and a Chinese board with two).
I tried almost all bifurching configs on several slots.
I understtod that best slot should have been no. 4 (the central one) but no way to see more than one single device.
When boards were in slot 4 and I changed from x16 to x4x4x4x4 channel #3 I got three beep system error and I must clear CMOS.

Can you suggest some ideas ?

Thank in advance

It depends on on CPU as I know 1680v2 definitely probably wont work and 2687w v2 should it depends
here is example from asrock, is is posible to imports that definitions to our bios?

Hi!
If anyone was in similar situation, I solved it unitentionally. I've upgraded from i7-4960X to E5-1680v2 - by a side effect now all lanes in bifurcation work stable, both NVMe drives are runing without an issue. Now I'm just wondering if that was limitation of i7-4960X or some problem with my unit or some socket fitting issue (all other features were fine and stable). Any guess? :)
