I just bought a ryzen 2200g, asrock b450 pro4 motherboard and 1 dimm of 16GB 3000mhz team tvorce Vulkan ram TLZGD416G3000HC16C01

It won't post motherboard just keeps restarting I didn't see this ram on asrocks memory list but pcpart picker I think the site was, said this memory is compatable? I tried all 4 slots no luck. Is this motherboard picky with rocking only 1 ram stick?

Install the memory in the A2 slot, which is the second slot over from the CPU. Then do a hard reset of the BIOS.

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.



If that doesn't work, then that memory is either not compatible with your motherboard OR you have another problem like the CPU was improperly installed and some pins were bent, or the CPU cooler is incorrectly installed and is tighter in one spot than another which can act like bent pins because it "cocks" the CPU in the socket, or some other issue like a standoff in the wrong place under the motherboard. Obviously, you need to make sure you haven't forgotten to connect everything, like the 4+4 pin EPS power connector for the CPU, to the motherboard.

Also, make sure the CPU cooler is connected to the CPU_FAN header. Most systems won't start without that being connected.

Then return the memory. It's likely that board has an older BIOS version that does not support 16GB single DIMMs. Those 16GB DIMMs didn't even exist when that board was first made, so if you have an older BIOS version then it's probable that could be the cause. If you have access to borrow some other stick of DDR4 in order to get the system to POST so you can update to the latest BIOS version, then you might be able to get that stick to work but to be honest you would be a LOT better off with a pair of sticks anyhow because that single stick will not give you dual channel performance, which means you are leaving a chunk of free performance on the table since the doubled bandwidth is not possible with a single stick.

A 2 x8GB kit would be a much better option.

I set up an rma for the ram and now I'm on the hunt for a new pair. It's hard to find a good but cheap pair of ram for this motherboard. Can you recommend a good but cheap compatablestick of ram? I'm going to preferably buy 1 stick first money is tight at the moment and than buy the 2nd one. Can you possably link a cheap compatable 8 GB dimm? Much appreciated

Those show as being compatible on the Corsair compatibility list for that motherboard. Should work fine.
Thanks I was just checking the motherboards support lost which is very limited and doesn't even show that they tested 3200 lpx on it. God what a pain in the azz asrock should really be testing more ram configurations to make picking ram alot easier.... So frusterated

The motherboard QVL lists NEVER show more than a small sampling of tested sticks. They simply don't have the time or the desire to do that. Memory manufacturers on the other hand have NOTHING better to do than to make sure that sticks work on a given board, so they pretty much test them all against a given board, or at least the core variation of a specific module configuration, and then call the rest of the sticks branched from that core configuration (same model, but red sticks instead of black, or RGB added, etc.) good.

So memory manufacturer list is always more inclusive because they don't have to test everybody's sticks out there, just their own. There are far fewer motherboards to test your own sticks on then there are sticks, from ALL the manufacturers, to have to test on each of your motherboards.

Makes sense never thought to check ram manufacturer that way. Well hopefully these 8 GB lpx 3200s do the trick thanks for the response
