By the way Dave when the bios is posted may you post an update for us or notification as soon as it is released?  Thanks a lot!

Hey Dave, any news yet on that bios update!

I think here there will be no new BIOS, at all...

I think here there will be no new BIOS, at all...

Seems that way... Not thinking about EVGA for the next High dollar Build...  They are acting like APPLE these days...  We got your cash now buy new or spin.

What's not fair is that it promised a new bios but only illusions were created, until now ...

With all due respect D ave we were promised the EXACT same thing MONTHS ago...

Most of us have just given up hope and rightfully so it seems.

Everyone should Email EVGA for an answer. Don't bail on EVGA just like that guys, just be proper about it and email them of when will it be public or if they could kindly release it if only ready

EVGA any answer at the moment! We have been waiting for a bit

Hi all - I know I'm a little late to the game here, but I just spent all weekend twiddling with a 512GB Samsung 950 Pro with a PCIe x4 adapter in my EVGA Z97 Classified.  
 
Long story short - I *finally* got spec speeds from the 950.  The trick for me was forcing the PCIe slot (I used slot 6) to Gen3 in the BIOS.  That was the only way I could get the speeds up.  Like everyone else, I was seeing ~800MB/s prior to that.  Once I forced the slot to Gen3, everything was perfect.
 
The only thing I don't love is that adding the 950 (via the M.2 adapter card) brought my GTX 1070 down to 8 lanes... I'm filing this under "oh well" for now as x8 vs x16 benchmark differences seem to be negligible. 
 

EVGA please

@bschimp
question, did you have slot 2 or below populated when you did the firmware update?  If you do not have a card in PCIE2/3/4/6 the PLX will not initialize and as such will not flash.
If you did, do you have a thumb drive you could make a DOS boot off of and flash in DOS mode, per the engineer it should work in Windows but they tested there on DOS.
 
If you are still getting an error, can you email me the pic if it is different than the one above as the engineer I am working with would like to see any additional errors.
 
@cdc951
It is a an update to the PLX firmware, to help it run at the correct speed when a SSD is plugged in.  Due to this fix taking a little bit of know how, and obviously there is some potential issues when done in the OS, I am talking with the engineering team about the possibility of integrating this into a different update, such as BIOS if possible.  First thing is getting the people who are having issues up and running correctly.  Also, we need to see if this issue persists on the Z170 Classified also, and if it is fixing that as well, which we are working on too.
