P3700 dissappeares after cold restart. ASUS X99WS/IPMI, Xeon E5 2670v3, 64Gb. All updated to latest FW/SW. Re-installing to ANY free pci-e slot fixes the issue until next system switch-off

IntelSSD CVFT50620001800CGN -

DeviceStatus: Healthy

Firmware: 8DV10151 ( upgraded using isdct utility)

FirmwareUpdateAvailable: Firmware is up to date as of this tool release.

ModelNumber: INTEL SSDPEDMD800G4

M/b ASUS X99WS/IPMI BIOS version 7.01. All drivers installed.

Xeon E5-2670v3, 64Gb ECC w/reg

PS 1200W

The only other device installed is GTX 970.

Win 8.1 Enterprise upgraded to latest version.

Windows boots w/o any problem. Warm restarting causes no issues. Green and yellow LEDs on the drive are on or blinking.

After system switch-off the UEFI BIOS screen shows no presence of P3700. No LEDs flashing.

The issue is fixed by installing P3700 to any other PCI-E slot on board. The system recognizes it , LEDs start flashing and Win boots succesfully.

After switch off the same thing occurs - no P3700 presents in UEFI BIOS.

ASUS tech support provided no answer since any other PCI-E card worked OK.

Pls help to fix the issue

Thx and regards

Nick_Gilkos,

We are going to check on this and will get back to you soon.

Nick Gilkos,

Some BIOS implementations may have option for additional timeout at the end of the POST (e.g. in BIOS for PCSD server motherboards of Grantley generation we have option " System Boot Timeout " in " Boot Maintenance Manager " tab in BIOS setup) - This allows additional time out for initialization for certain devices. You may need to check with ASUS if they have this.

Alternatively, it may happen that for some reason there is not enough power for the Intel® SSD DC P3700 Series to start up because there may be many devices starting up simultaneously. You may try enabling staggered spin up on HDDs if there are many connected and if such option is available in BIOS.

Could you please check if clearing CMOS without drive re-installation to different PCIe* slot can help? If so, it may indicate BIOS issue which needs to be investigated by ASUS.

When you are cold booting the board and the Intel® SSD DC P3700 Series is not seen in BIOS, can you boot to EFI shell (if possible on this particular motherboard) and list all PCIe* devices by pci command? It will show if board recognizes the P3700 or not.

It may happen that the P3700 is in PCI devices list but not showing as bootable device which is a different situation. We also wonder if you could check this driver in a different motherboard to confirm it is healthy.
