820-00928: Not recognizing SSD

Have this board that doesn't recognize the SSD. I've tried clean bios with same issue.

PP3V3_SSD_NAND, PP1V8_SSD_FMC, PP12V_SSD_VPP all come on to their respective voltages, but after a few seconds, they all drop out. After about 5 seconds PP12V_SSD_VPP try to come back on, goes up to 10/11v and drops out immediately

PP3V3_SSD_LIM - 3.3 and remains on
PP1V8_SSD_DRAM - 1.8 and remains on
SSD_PGOOD_L - 1.8 for 6 sec then drops to 1.6

SSD_PWRCON1 - 1.8 then drops out after 6 seconds. (not able to access to SSD_PWRCON0)

Any other suggestions?
