Re: [PLUG] Memory Problem on New Build

["Adam Schaible" <plug@schibes.com>]

Hi Casey - 

I have two Ryzen boxes at home and while they're extremely powerful I did run into a fair number of build/setup problems up front, and not just with hardware, but kernel support too. However instead of griping (more) about my issues let's focus on yours. In order:

1) The 8-pin CPU power connector alone should be enough. Don't worry about the extra 4-pin, this connector is for "pro overclockers" who need even more juice. So you should be good there.

2) Is your Ballistix RAM "RGB type" with rainbow color LED lighting built in? Multiple reviews indicate this board has multiple problems with RAM of that type. Do you have even a single stick of slower DDR4 you can "borrow" from some place else just for testing? Regardless of that I would still recommend, long term, returning that RAM and buying something off ASRock's recommended list.

3) If your Ryzen is incompatible with the motherboard BIOS it won't even POST (power on self-test). The very fact that you see error code b0 indicates that POST is running, it's just failing. If you *didn't* see that error code you would have had to do a BIOS upgrade (possibly even involving a CPU swap, like I had to). That being said it's not a bad idea to do a BIOS upgrade at some point, ASRock tends to be a bit more "aggressive" with pushing product out as quickly as possible and then tweaking it later on because of the demands of their core customer base. There is yet another generation of Ryzens coming out later this year (AMD is really on a roll these days!) and they will almost certainly require BIOS upgrades to boot up.

Good luck and let us know how it goes -

I'm putting together a Ryzen 7 2700x system, but I'm getting a memory

error when trying to boot.  Could some of you fine nerds help me

troubleshoot this?

I got an Asrock X470 motherboard that has a 2-digit BIOS boot

indicator.   I've put in 4) DDR4-3000 16 GByte SIMMS.  To power it, I

got a 750 Watt Thermaltake power supply.  The motherboard has sockets

for a 8-pin AND a 4-pin power connection, but the power supply only has

an 8-pin plug.  The 4-pin I left empty.

Booting brings up the groovy RGB lighting on the motherboard and all the

fans, but the display quickly reads "b0", which the manual translates as

"Problem relating to memory".

I've got a couple of hypothesis, but all require swapping components to

test.  Would you let me know if you think these are likely, or if I

might have missed something.

1.  The motherboard needs the extra 4-pin 12 volt source, and/or 750

watts isn't enough to bring up the memory.  I tried removing half the

memory and also the video card, but that did not help.  I also built a

cable to steal power from the PCI socket on the power supply and plugged

in the 4-pin.  No change.

2.  The memory is incompatible.  The brand I bought "Ballistix

DDR4-3000" is not on Asrock's official approved list.  Also, AMD suggest

DDR4-2933 as the fastest memory.   I thought it would work, but I'm

confused by memory specs.

3.  The motherboard's BIOS is incompatible with the latest Ryzens.  I've

heard of this happening, but I'm not sure how to test this.

Any thoughts or suggestions would be greatly appreciated.

TIA!
