Asus X99 Deluxe: RAM not fully recognized or unable to boot

post #1 of 10
Thread Starter 
Hello there,

I built me a new computer (Asus X99-Deluxe, i7 5930k, 32GiB Corsair 2666MHz CL16 RAM) some months ago. Since the first day, I'm experiencing weired RAM related issues and I still could not fix them.

The problem:
Either the computer is not booting at all (Q-Code: "bd") or the RAM gets not fully recognized.

What I did so far:
  • I checked the RAM slots on my board. All of them are working fine if I use a single module.
  • I exchanged my RAM modules. Used 4x8GiB RAM before and changed to 8x4GiB without any success (same Corsair modules).
  • I updated my BIOS to the latest version.
  • I tested MANY different voltage and frequency combinations (DRAM Voltage up to 1.35V, raised System Agent Voltage, raised VCCIO CPU Voltage, ...)
  • I tested default BIOS settings and selected the 2666MHz XMP Profile.

It seems like I can run the computer fine with a target DRAM frequency lower or equal to 2250MHz 2000MHz (2250 only works sometimes). Everything above (regardless of my voltage settings) will lead to the "bd" error code while booting (or the RAM not beeing fully recognized).

BIOS Settings:

I hope someone can help me to solve this annyoing problem.

Best regards

Memory
8 x DIMM, Max. 64GB, DDR4 3200(O.C.)/3000(O.C.)/2800(O.C.)/2666(O.C.)/2400(O.C.)/2133 MHz Non-ECC, Un-buffered Memory
Quad Channel Memory Architecture


Anything over 2133 has to be manually overclocked in the BIOS. XMP will not work. You have to set the speed and timings manually.

You should be able to run 2400 and possibly 2666 at the 100BLK which my help stability. I know I run my Corsair LPX at 2400 12-12-12-32-1T (1.3 volts) and 100BLK along with a 44 multiplier on the CPU 1.25 volts and 4ghz cache

Allright, thanks for your answers. I will try the 100BCLK. But setting the CPU multiplier above 38 (or something) automatically enables Turbo Mode. I've read some overclocking guides in the past and most of them recommend disabling Turbo Mode. What drawbacks can I expect with enabled Turbo Mode?

Ok guys, I switched to 100MHz BCLK and tested several manual timings with a DRAM frequency of 2400MHz. The "bd" error shows up less frequent now, but I'm still not able to get all modules recognized mad.gif

I even tried huge timings like 30-30-30-45-2T without success. Currently I'm testing the default timings (16-18-18-35-2T) @ 2133MHz and it looks good so far.

But how are you able to run your RAM at 12-12-12-32-1T @ 2400MHz and I can't even switch it to 2400MHz with default (or huge) timings? I have two Corsair Vengeance LPX 2600 CL16 kits with a total of 8x4GiB = 32GiB.

Are those "mixed memory"? Are part numbers and the rev numbers on all the sticks all exactly the same?

Can you recommend me a good (beginner) guide for DDR4 overclocking?

Yes they are all equal and I got the same problems with my single 32GiB kit I had before (4x8GiB) :/

How can you disable turbo mode?

Have you tried to change DRAM training from Auto to Enable?

Advanced menu -> CPU configuration -> Turbo Mode
