Gentlemen, I'm having a very similar issue as the previous poster, except that I'm most certainly using a (4+4)pin for CPU power location 9 and a (4)pin for CPU power location 2. I get blue and green lights on the motherboard, yet not fans spin and the Debug LED does not show any post codes. I'm stripping down the case in the morning to try to post just the MB (TaiChi X399), CPU (1900X), and a single stick of RAM (Trident-Z 3200MHz CAS 14) with the PSU (1000W Seasonic Prime Titanium). Unfortunately I don't have a molex to fan connector, but the PSU does come with a tester for the 24 pin MB cable.
Thoughts?

Update: I have removed the X399 TaiChi from the MB, and tested with a new PSU that is working on another rig. Same conditions as before, LEDs on the MB light up but no fans and no post. I have swapped the CPU Power Cables too with the same results. I have updated the BIOS flash via a USB following the instant flash instructions and successfully updated to 2.30 and 3.30 (using "creative.rom" and the USB slots to the right of the Audio on the bottom, and holding down the BIOS Flash Button on the MB. The MB cycled through flashing green lights until stopping which is the success state. Cannot get into BIOS to confirm, because of a lack of post). I've tried reseating the CPU itself, this did not help the situation.
Going to RMA both the CPU and MB to be safe, as I just purchased the parts this week. |
