Ryzen 7
(2x8) 16gb of Corsair Vengeance LPX DDR4 3000mhz CMK16GX4M2B3000C15
Asus B350-f strix motherboard

My new Ryzen system has been working wonderfully however I've had some trouble with my ram. If I attempt to clock my ram to anything above 2133mhz it fails to boot. I checked the ram support for my board and it is supported according to asus. I also went ahead and updated the bios as Ryzen is fairly new. When attempting to raise the clock speed I simply left everything on auto so perhaps I missed something there as I'm not super familiar with overclocking ram(If you'd even call it that). Appreciate the help, thanks.

I have heard about an issue with the ASUS bios that it is failing to support high RAM frequencies. If your RAM is stock clocked at 3000MHZ, it should work on default to that speed. If you can provide some details of the stats on your memory tab on the BIOS, that would help. Also how many DIMM slots are there on your motherboard.Thanks and good luck!

I have 4 DIMM slots and I checked the manual to make sure I'd put them in correctly. I went ahead and loosened up the timing from the previous ones posted by ASUS and it allowed me to boot with 3000mhz. Everything seems to be working alright but I'll probably stress test it to make sure.

If i may ask, what timings did you use? I have the same board + ram setup and can't get above 2800MHz no matter what the voltage is.

@mika.lukkarinen89 Make sure you've performed the latest non-BETA BIOS update for your motherboard as this will impact compatibility for a lot of kits. If it sill has issues, please PM me your motherboard and CPU models, RAM part number, Lot/Serial number, and version number that is on the side of the individual modules.

I cant seem to PM you, but Ive been having the same problem and have now bought 2666 Vengence RGB and 3000 RGB and it still clocks at 2133 :(

Motherboard:
ASUS ROG STRIX B350-F
BIOS 0811 x64
Build Date 08/25/2017

2666 RAM:
CMR16GX4M2A2666C16
DDR4 16GB(2X8GB) 2666 MHz 16-18-18-35 1.20V ver5.3
172900632203698

3000 RAM:
CMR16GX4M2C3000C15
DDR4 16GB(2X8GB) 3000 MHz 15-17-17-35 1.35V ver3.32
173400028629783

I cant get the timing or the RGB effects to work via Aura, and Im super bummed. Ive always been super loyal to Corsair RAM and Asus Mobos, but this is crazy :(

Has anyone had any luck with getting the memory to there stated speed, I have the b350 f gaming, ryzen 7 1700, 16gb dominator platinum 2666mhz. When I first got my build up and running I managed to get the stated 2666mhz frequency but as soon as I updated the bios to 0809 I couldn't get passed 2400mhz I've since updated to 0902 but still no luck

Hi Corsair Nick. I have the same problem.

Same mother board, AMD Ryzen 5 1600x, and g.skill ripjaws 4 3000mhz cas15 (F4-3000C15D-16GRBB)

Here's a screenshot of what I have. https://imgur.com/a/SgCSR

I tried manually changing the frequency in increments but anything above 2133 just POST crashes. I even tried the DOCP option in EZ Mode.

Someone figured it out on reddit for me (r/overclocking). My BIOS was already updated when I posted this. I was told to raise my DRAM voltage to 1.4v. It crashed but after bringing it to 1.41v, it started POST'ing fine.

I'm having the same issue here. Bought Corsair Vengeance LPX Black 16Gb DDR4 3000Mhz and I can't get it to clock above 2133 without getting stuck in a post loop and then booting into the bios "safe mode"

I know this thread is a couple of months old now, but I'm having the exact same issue with the exact same RAM. I cannot get it to boot past 2133MHz. Corsair Vengeance LPX 3200MHz, bought earlier this year from Amazon. This is starting to look like a trend
