Aurora R9, i9900k, 64GB RAM, upgrades

Hi all,

so hoping someone can help. Originally my Aurora R9 had a i9300 processor and 8Gb memory.

Purchased 64Gb memory and it ran fine with XMP1 at 3200Gb. All good and happy πŸ™‚

So just got a i9900K and swapped out the processor, it flashed 4 orange led's at boot.

Eventually I can get 32Gb working with one 16Gb stick in the white slot and one in the black.

I can get 16Gb working as every single stick, go above 3 and it fails, Put two in white slots it fails, put two in black slots it fails!

Tried multiple setting in BIOS and XMP1 which is only one showing works with 16Gb or 32Gb, XMP off works the same. Set any overclock and it fails!

CPU at 39 degree C.

Any ideas most welcome.

thanks

Hello,

Had this problem also. Solved yesterday. i9900k/ 64GB corsair 3200 ram. 

What I did. 1:Unplug and discharge power. 2: Remove CMOS battery for reset. 3: Installed 3 x 16gb sticks in the two white slots and the black in the middle of the two whites. 4: reinstall CMOS battery and power and bootup. System restarts a few times by itself and boots up with 48gb ram at XMP 3200. 5: Noticed there is an intel chipset driver update in the DELL driver area and install that. 6: Power down and discharge power. 7: Install last stick on the last slot closest to the CPU. 8: Boot and voila! 64GB running at XMP 3200.

Not sure if it was the chipset driver that made the difference or the install order of the sticks, but it works great now!

Cheers

@gl3n    Eventually I can get 32Gb working with one 16Gb stick in the white slot and one in the black.

Now that is the most peculiar aspect of your dilemma. That should not work. Where did you purchase the i9-9900K?

One white one in black just means it's running in single channel mode.  Not as good. 

Try clearing cmos by removing the  cr203e battery out of mobo.

Online reseller in new packaging and unopened. Looks completely legit and shows everything correctly in CPU-Z

clear cmos.

check each stick one at a time including going into cpu-z and reading the SPD.

Then use 2 pieces in the first bank aka White Ears.

The order is 1 then 3         2 then 4

Not 1 then 2    3 then 4.

Try 1 then 3

Then add one stick in slot 2

then add the last stick in slot 4

DELL uses 1.4v XMP profile.

Mixing Density and Vendor and Speeds is not recommended.

Start with one then add another until all the slots are filled in the correct order

The other Really Bizarre thing is the labeling of the Ram slots.
