@noInk Showing only 3 gb with 2015

@SkOrPn tried one by one the result has not changed

MotherBoard Hp Z800

Cpu 2x X5680

@bloodfor

Does this also crash on your system?
On the DUET USB replace the Efildr20 with this file

Ah OK, so its a true Workstation with 12 cores of Xeon goodness. I want one of those... lol, I'm sure your RAM is fine then... I miss my Xeon system.

@SkOrPn

The 3GB is supposedly an issue with the memory remap thought to be fixed on 2015 > 2017.

thank you for everything

@bloodfor

Is the memory check happening with this build on your system and the right size is reported?

Can you also check on that if something change?

if it doesn't work with this one, perhaps the issue is something else.

Thank you noInk,

All I had to do was go into EFI shell from the REFIND UI screen and then select the boot partition - FS1 in my case - and run Bootx64.efi (I think) and then the system booted off the NVME drive. When rebooted REFIND had worked out the Win10 drive and this time it booted as soon as I clicked on the Win10 icon. All good.

So if anyone else is looking, if you have a Windows 10 installation already on your NVME, REFIND will find it. Follow the scheme that matches your situation and if necessary go into the EFI shell from REFIND and run the appropriate Bootx64.efi file and it should all work out.

Thank you for all the work you have put into this to allow us to keep our older x58 alive and useful.

I have successfully setup my NVME boot drive with the following:
EVGA X58 4 Way SLI (E762) – The greatest generation of motherboards.
CPU is Intel i7 980X (water cooled)
Corsair DDR3 48GB RAM (6 x 8GB)
GTX 580 + GTX 580 (water cooled)
Flash memory (8GB ) with small form factor for DUET/REFIND
Samsung 970 EVO PRO 1000GB M.2 drive
PCIe x4 M.2 card NVME
The problem I'm having is the link speed on this mobo. On the EVGA SR-2 with the same exact hardware addons(different graphic card RTX2080 TI) I get full PCIe x4 bandwidth and benchmark read speeds of 1600-1700 MB/s.

On the EVGA 4way classified I get read speeds of 800-880 MB/s. As you can see the report from HWINFO64, the link width is x4 but its performing as PCIE 1.1

As you can see the temperature is good so no temp throttling of the drive speed is occuring.

The GTX580 will idle at PCIE 1.1 2.5GT/s speeds but when stressed will increase back to full bandwidth PCIE 2.0 x16 5GT/s which is normal behavior but the NVME drive will not throttle up, regardless if graphic card running at full speed. NVME current link speed should be PCIE 2.0 x4 at 5GT/s, will not get 8GT/s since slot is not PCIE 3.0

I've installed samsung drivers, Windows 10 is at 1903. Even checked with new clean windows 10 install, no change still at slower bandwidth.

I've tried different PCIE slots: (currently only GTX580 and PCIE adapter installed)
PCIE 1 (x16): GTX580
PCIE 2 (x8): none
PCIE 3 (x16): none
PCIE 4 (x8): none
PCIE 5 (x16): none
PCIE 6 (x8): none
PCIE 7 (x16): NVME PCIE x4 adapter

Doesnt matter which slot the adapter is in, obviously with the 2 GTX580 would not place the adapter in adjacent x8 slot, but nothing changes the bandwidth.

Bios CMOS reset to default values, so no overclocking. Have tried setting RC bridge, Memory gap --> 3g but to no avail.

Is there a bios setting that will give me the PCIE 2.0 x4 bandwidth, i.e. link speed at 5GT/s?
Does the DUET/Refind UEFI overlay bios take a long time to load(> 80 secs)? I've tried CLOVER UEFI and its a bit faster to load( <30 secs) but nothing compared to the EVGA SR-2 load times (< 5 secs) which has an AMBIOS bios. EVGA 4 way has a Phoenix bios (EVGA latest at 58).

Any input would be helpful, Thanks!

I'd also like to report that DUET/REFIND UEFI loader can be installed on a SATA drive, avoids having to use a USB flash drive, if you have a spare SATA drive available. Can use the extra free space on the SATA drive for storage or whatever.

Just remember the drive has to have MBR, has to be active and has to be set to boot.
Cloning the flash drive onto the SATA drive as below sets up the partitions correctly to allow booting to DUET.
You just set the BIOS to boot from that drive first.

You can also clone your existing system drive onto the NVME, but it does require you to set a GPT partition when cloning so that DUET recognizes the NVME drive.

Above is an example, obviously you would have an unformatted/unpartitioned NVME drive to clone to, or you can setup partitions using the wizard before hand and copy the relevant partitions to your NVME.

I used Minitool Partition Wizard to do this.

This worked for both my EVGA SR-2 and 4way classified(e-762). The problem I have not solved yet is the E762 bandwidth limitation and why I only get PCIE 1.1 x4 link speeds. There are no problems on the SR-2 as I had mentioned.

Obviously there are other methods to do the above with other tools like Rufus, Diskpart, etc. I found this the easiest way.

@docdude

Should take less than few second to load.
Does it happen across all the version or did you notice any change on 2015/2017/2019?
What about if you replace the EFILDR20 with the file on this archive?
https://drive.google.com/uc?export=downl...HjHU1Jl6ad3bRvs
Does the PCI1.0 happen also without DUET EG. NVME drive @ storage?


If all version have the same issue you may need to remove the BIOS F2 phoenix AH_P10710_ROM and replace it as PCI ROM with a less bug ridden intel iCBD (ICHAAHCI) also, notice this may not actually solve the issue.
If you don't know how @Lost_N_BIOS may be able to help you, try to ask.

Thank you for responding.

It happens with all versions. I tried disabling onboard devices like 1394, LAN, etc. but still have the same issue with slow loading. On my EVGA SR2 mobo with American Megatrends bios it loads in a few seconds. Have used EFilDR20 compiled without 1394 that you posted earlier and it has the same issue. Ill try the one you just posted and report back. The PCIE 1.0 slow link speed also happens without DUET.
I'll reach out to @Lost_N_BIOS, I'm sure its a bios issue.
Ive also posted on EVGA website to see if anyone has had same issue.

@docdude

Might be just that phoenix ahci rom doing, especially as F2 module. Remove it from your BIOS and find a valid PCI ROM alternative.

Lemme know if removing the F2 ROM fix alone the issue with the PCI-E link.

In case I could also do the changes but a way to reprogram the bios chip in case of failure is on you (an hardware programmer)
Things you'll need:
The reported DEV_ID of the Intel Chipset SATA RAID Controller. (PCI\VEN_8086&DEV_????)
A link to the actual bios file.

I'm working on it now. This has been tried before on the EVGA boards, phoenix AHCI removed and Intel AHCI module used instead: AHCI mod

I found a ICHAAHCI.bin version 1.20e, there is also a newer 2.00h rom. I have that as well but it seems like these guys in 2011 used the 1.20e version with success... the EVGA E-762 mobo booted no issues. I am currently looking for that modded bios to compare to the one I'm modifying. I've removed the BIOSF2 old phoenix AHCI and replaced with ICHAAHCI as a PCI ROM

Before:

@docdude

Yea, just replace the PCI ID and return sum 0 on the OROM if needed.

/biosf2 release

/pci OROM.BIN

See the second PM I sent you. Be advised the PCI ROM will work only when the BIOS is set to RAID mode.
This will also act as failsafe since by default the BIOS is set on IDE.
