RAM not recognised in EUFI?

DJai · 3 Jun 2020 at 13:05

Brand new hardware.

ASRock B450M Pro4-F, AMD B450, S AM4, DDR4, SATA3, Dual M.2, 2-Way CrossFire, Realtek GbE, USB 3.1 Gen1 A+C, MicroATX

AMD Ryzen™ 3 3300X, AM4, Zen 2, 4 Core, 8 Thread, 3.8GHz Base, 4.3GHz Turbo, 18MB Cache, PCIe 4.0, 65W, CPU

Crucial Ballistix BL2K8G32C16U4B 3200 MHz, DDR4, DRAM, Desktop Gaming Memory Kit, 16GB (8GB x2), CL16, Black (not changed speed from default in settings). It's definitely pushed in all the way and sat in the correct slots according to the manual.

Elsewhere it's showing:

Please help,

Thanks.

Argh! What a stupid mistake.

I've got a Windows USB plugged in and it crashes immediately so I'm thinking it is definitely the RAM.

I thought I checked this before ordering.

Thanks, I looked through the list.

https://www.asrock.com/mb/AMD/B450M Pro4-F/#MemoryPR

It looks like there aren't any RAM modules that support 3200 speeds on both slots 2 & 4. Am I right?

I've seen a lot of bad reviews of Corsair RAM used in conjunction with AMD CPUs.

Can you see what I mean when referring to the list, it mentions 2/4 for 2933 but none of the 3200 modules?

DJai · 3 Jun 2020 at 14:18

Ah, so it's not referring to slot 2/4, it's referring to number of modules. Thanks for your list.

DJai · 3 Jun 2020 at 14:27

Thinking about it, should the board even be able to read the DRAM if it's not compatible?

I can't see any reference to any retailer in this thread.

DJai · 3 Jun 2020 at 14:41

Done, I'm a bit miffed because there are loads of RAM modules not on the QVL that work and now I want to be sure this definitely isn't compatible before sending it back.

DJai · 3 Jun 2020 at 15:12

Saved settings, restarted, wouldn't boot the USB drives and EUFI reporting no RAM again.

DJai · 3 Jun 2020 at 22:05

Shall I go for
Corsair CMK16GX4M2B3200C16 Vengeance LPX 16 GB (2 x 8 GB) DDR4 3200 MHz C16 XMP 2.0 High Performance Desktop Memory Kit, Black?

DJai · 3 Jun 2020 at 22:08

I left everything at default initially and auto. You can click the image to see it larger can't you?

DJai · 3 Jun 2020 at 22:17

Oh damn it, I think I should have held off returning. Now I remember using the compatibility checker: https://uk.crucial.com/memory/ddr4/bl2k8g32c16u4b/CT16835955

It says 100% compatible.

I haven't yet found anything referring to voltage.

It's already with the courier...

DJai · 3 Jun 2020 at 22:22

I know. I'm so torn now about what to do.

DJai · 3 Jun 2020 at 22:38

Better to go for that over the kit I've just sent back because it wasn't correctly configured and therefore not tested properly?

DJai · 4 Jun 2020 at 06:36

I'm going to find out, I've reordered the same kit. Let's see what happens. Need to remember to increase voltage.

Do I leave the Ryzen infinity fabric settings alone?

DJai · 4 Jun 2020 at 19:29

Thanks Tetras, I'll be sure to do that. The last time I built a system you just installed the RAM and it worked...

DJai · 4 Jun 2020 at 20:11

Basically anything over 2566 isn't native and is classed as overclocking/default voltage is not correct.

DJai · 4 Jun 2020 at 20:49

Thanks for clarifying
