Question What happens if RAM speeds aren't compatible with Motherboard?

[PCguy12345]

Hello,
I am building my first PC and it won't boot. However now I think I know the solution, motherboard the B450M Gaming from Gigabyte
( https://www.gigabyte.com/au/Motherboard/B450M-GAMING-rev-10/sp#sp )
says on it's website that it only compatible with DDR4 3600(O.C.)/3466(O.C.)/3200(O.C.)/2933/2667/2400/2133 MHz memory modules, I have 3000MHz from Adata
( https://www.amazon.com.au/ADATA-Spectrix-DDR4-3000MHz-Memory/dp/B07N244VYH )
Is this the reason my PC will not boot to Bios?

All ram/motherboards conform to Jedec memory standards which means companies involved in ram and motherboards have set default values of 2133/2400 or 2666 frequencies prior to enabling XMP to further increase speeds for capable ram. Your ram being 3000 isn't the reason for no boot.

Not sure why Gigabyte lists 2933 as non OC because afaik that'll require XMP which i thought the initials OC implies. I believe your motherboard would operate your 3000 ram at 2933 under XMP operation unless overclocked manually.

Please list complete specs

Thank you.

Have you followed the guide?

Do you get power at all?

Where is the video cable connected?

Have you connected the HSF to cpu_fan header on the motherboard?

I have followed a guide and manuals, I do get power LEDs and fans work fine, the DVI cables is connected to a monitor and GPU. And finally yes I have connected the HSF to the cpu fan header.

Is the DVI cable connected horizontal or vertical at back of PC?

horizontal

Sorry PCguy not sure what else to suggest for the moment. Hopefully someone else jumps in.

That okay, do you think I should get it checked out at a store?

Wouldn't hurt, maybe wait a bit for someone else's suggestions but up to you.

Maybe try Hdmi TV? Just to rule out monitor or cable. Hope you have either a Hdmi TV and cable.

Yes I have already tried that and the monitor works fine with console and laptops as well as the cable.

The maximum supported jedec memory for the R5 2400G is 2933MHz, which is why it's not (OC), and there's multiple 2933MHz ram with native speeds of 2933MHz, not an xmp setting that's usually found on ddr4 with a 2133 native speed.

(OC) isn't always just an xmp, it can also mean you may need to adjust the bios settings to increase memory controller voltages or set manual settings to get stable, rated speeds etc, which technically is OC. Which is why non-OC boards will not list (OC) speeds, only the maximum cpu supported speeds.

Oh, and if you read the QVL, there's a ton of 3000MHz supported modules, from all the popular vendors, regardless of what the website states.

My guess would be that you got a board from the back of the shelf, one of the original B450 chipsets, so has a really old bios. While most ram issues with Ryzens were fixed by the 2nd Gen, every now and then you'll get one that's just not liking the ram. Ryzen work best with dual channel setups, they aren't fond of single channel or even 2x dual channel (4 sticks). If putting the single ram stick, it should be in slot A2. (that's 2nd from the cpu).

Pull the power plug from the pc. Hold down the power button for 20 seconds. Open pc, pull out gpu, pull out the battery behind it. Wait 10 minutes. Replace battery, gpu, plug in pc and see if it boots.

Try clearing CMOS. Should be instructions on how to do so in your mobo manual if you don't know how.

Okay thank you, i'll give it a try

Do I need a new CMOS battery?

 

[Karadjgne]

I wouldn't think so. I'm still using the same cmos batteries after 7 years on both my pc's. The only thing the cmos battery is responsible for is maintaining voltage to the cmos chip so that it'll retain its memory. That's taken over once the psu kicks in.

One guaranteed way to know if the battery needs replacing is your clock in windows. If it starts showing incorrect dates and times, cmos/bios lost power after shutdown.

I've tried your recommendation but unfortunately it didn't. I will take it into a store to get it checked out.
