ASROCK x570 cant boot or get into bios menu

[MrBrac]

So I been having a lot on and off issues with my unraid as you can see from my history.

 

I took a break from it. Well since then I swapped the entire motherboard with a new motherboard.

 

The history is this I went to upgrade my 32gb ram to 64gb. I lost my original 32gb ram. and ended up actually with 16gb ram with 2 sticks so 2x8.

 

So I ended up buying another 2x8 and making it 4x8. So now I started to have issues with my boot and I had to manually set f11 boot to unraid. I could not access the bios menu anymore it would not work.

 

So much later I swap entire board hoping to fix it. I broke my cpu fins T_T. so now I upgraded from whatever I had to a AMD ryzen 7 5700X.

 

Same CPU. so I realized it should be the ram right if I am still having same issue?

 

The ram mhz speed was 3200 mhz. IS that the cause? I tried reseting cmos via pins and other methods. I removed ram and made it just 2 slots A2 B2.

 

But no success. the system boots into bios and hits A2 which means cant find boot disk?

 

but USB unraid is there and NVME of windows boot.

 

should I downgrade ram in mhz speed and see if it boots. I am just lost at this point and tired.

I have some machines with that combination (CPU + x570).

None of them can run the RAM at 3200Mhz!

The "best" works with 3000, but another can only stand 2700.

 

Start with 3000 and step down (lower limit 2400) to see if it helps. Use memtest (NOT the one from the UNRAID stick! Download the new version and use a seperate stick) to check for errors. Repeat until no errors remain (can take a week or so)

 

The Ryzen seems to be very picky about RAM speeds. But once tuned in correctly, no issues anymore (NEVER change / add RAM afterwards! There is a "burn in" phase where the modules get aquainted to each other. If you change one of them or add new, this does not work anymore. Reset the Bios and start fresh then)

I cant reset or even touch the bios the pc is stuck at A2 and I cant get into any menus. The mobo is brand new from a swap. I think I will get some way under 3000mhz ram.

 

thru some odd luck at amzn I found out I had bought 32gb 2133mhz ram.

update new ram in and low and surpise it wont BOOT. I am at my wits end. I did everything I can think off I took out usb unraid I even took out the m2 with windows boot. I cant get this POS to run.

 

Bought used ASUS ROG STRIX 570-E gaming mobo. I am sick of asrock.

Are you saying that you cannot even get the system to POST and the BIOS screen to come up?  That would strongly suggest some fundamental hardware related issue, although no idea what.

I get to bios and mobo says A2 at drMOS error. Its shows asrock logo and says F2 or del for bios and f11 for boot menu

 

But no key combos work.

 

The mobo wont work. This happend on older asrock mobo and swapped for a new mobo. 

 

I can not get this board to work at all. Ive tried swapping cpus, multiple ram.

 

@itimpi I swapped like entire board for new ver of same board. I tried so many things like removing sas card , removing m2 boot , removing usb unraid boot.

 

At this point I want reformat my unraid and stuff and redo it with my new asus mobo coming.

 

I upgraded my cpu , I broke the pins on swap(getting rusty). So I went from like 1700x to 5700x. All my issues happend when I swaped 32gb ram to 16gb by accident.

You will need to make sure that the new board posts correctly before trying to plug in extra cards or even trying to Unraid

 

It is very unusual for two motherboards to both fail to post.   Could it be something less obvious like a power issue?

EVGA PSU 650 watts , I mean it powers on and everything , I looked up asrock a2 errors and a lot people have issues with this damn board being a psycho. I thought was the ram that messed up board at first and possibly that new board is not updated for 5000 series. There is supposed be a sticker on board showin bios ver but ofc no sticker.

So somehow I got replacement mob really fast , when I get this over with and fixed im tempted to just reformat my unraid and start fresh.

 

so I just did a swap to ASUS ROG x570-e gaming and I just put in m2 and a 1050 ti and put some power and low and behold IT RUNS AND GOES INTO BIOS. ASROCK = SHIT

sad to say this little bastard is culprit and lasted a long time in service to me.

 

when I swapped and plugged this boy into sata the ASUS stopped at A2 and had same odd bios issues.

 

This guy prevented me from bios and tricked me. But I had some issues with asrock so I am at peace with my new used ASUS ROG X570-Gaming E.

 

Live and learn , gonna have to reset my cache and im gonna just reset all my disks.
