Hello everyone

as the title I have a problem with the Rams gskill flare x

F4-2400C16D-16GFX

and MB X370 killer sli

the system becomes unstable (BDOS) with any frequency of the ram, only  2133MHz seems to work properly.

I tried it with 2400 MHz, 2600MHz, 3200 mhz

I run a memtest with no errors.

I tried with timming / voltages in this table, but nothing seems to work (only 2133MHz)

I updated the BIOS to UEFI version 2.0

any suggestions?

And this is with the two sticks in mem slots A2 and B2? If not, reset you BIOS after moving them but before booting.

G.SKILL's RAM Configurator recommends your model of memory with your board:

http://www.gskill.com/en/configurator?manu=52&chip=2952&model=2988

Your board is also listed in this model's QVL list:

http://www.gskill.com/en/product/f4-2400c15d-16gfx

How are you setting the timings? Are you using the XMP profile, or setting the timings manually?

What is the Command Rate (CR) set to? The Ryzen memory controller works better with a CR of 1 at memory speeds above 2133.

Did you try increasing the memory voltage beyond 1.2V? If you over clock your memory beyond 2400, you normally need to increase the memory voltage.

Your memory should work at 2400, but any speed above that is an over clock beyond its specifications. In general and in my experience, G.SKILL memory does not work well if at all beyond its highest rated speed. If lower speed memory models could be easily over clocked to higher speeds, the market for their higher speed products would be small.

This is why I bought the flare x, but any frequency beyond 2133MHz does go BDOS the system.

I manually set the timming, turned up the voltage to 1.3v, 1.35V, 1.37v

command rate is over T1

I tried all the timming in the table

2400MHz with 15-15-15-15-39, 16-16-16-16-39, 1.35V

but nothing seems to work

Great, glad it works for you now!

AMD is still providing updates for memory support for Ryzen. There is a new BIOS version for your board, 2.00, that may work even better.

A lot of 370killer users (includes me)report that 2.00 can't set the ram above 2400mhz  same as 1.70.The only working version is 1.93a
