Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

Your MOBO show support for the Pro 3700 65 watt with BIOS version P5.50 and 3700X 65 watt with BIOS version P5.40.

You may just need to download the Bios that corresponds with the specific 3700 CPU you bought. 

Ok you have the 3700X so you will need BIOS version P5.40. 

Wow my MOBO CPU support list changed the last time I checked it would only support up to the Ryzen 7 2700x. Now I can use up to the Ryzen 9 3900XT or 3950 CPU. Though I must admit its been about 8 months since I last checked my support list. We both learned some new things today.

Oh thanks again Elstaci your post made me realize I needed to search a little deeper to help with this issue. Though I had to wait due to the 10 minute post flooding thing to pass this info on to this thread.

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

What BIOS were you on? Does it say 6.00 in your BIOS currently? (with old CPU)

IF you were on an older than P3.50 ..then you'd have to update to THAT version before updating to P5.10 .. THEN AFTER updating to P5.10 .. you can update to P6.00

There is an order that needs to be followed IF you didn't follow the flashing order, THAT could be your issue. The 65wt TDP 3700x should run just fine on your motherboard if the BIOS is properly flashed/updated

ALSO

With your old CPU installed .. Make sure to install the latest AM4 Chipset driver from AMD.com and THEN start flashing

Make sure your RAM is installed in slots A2/B2 (2nd and 4th slots away from the CPU socket) IF you are running only 2 sticks of matching RAM

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

I agree with elstaci..
My 370 board would at least boot and was listed as working with 3700x..
It was a good quality Asus which had no problems from the day I purchased it, but the VRM's were not man enough...

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

RE: ThreeDee
 It does say v6.00 with my old CPU when I load into bios. I think I missed one of the Chipset drivers. Can I temporarily downgrade my BIOS in order to download the drivers I need?

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

Yes, on page 6 of the ASRock Display Recovery SOP you can see Method 2

<Method 2>
Downgrade the BIOS
temporarily and install a new driver from ASRock website
1. Please check the BIOS download page
https://www.asrock.com/mb/index.asp#AM4
Download a BIOS version that is older than a BIOS with PinnaclePI AM4_1.0.0.5/1.0.0.6.
Use Instant Flash to downgrade the BIOS.
(*Please refer to the ASRock website and make sure the CPU is supported by the old BIOS version)
2. After downgrad ing the BIOS the system should be able to get d isplay output under the OS.
Please start the system to boot into the OS.
3. D ownload and install AMD all in 1 with VGA driver ver:18.10.20_NHDA_WHQL or later
version from ASRock website:
https://www.asrock.com/mb/index.asp#AM4
4. After the driver installation please make sure that device manager show s graphics driver
version 24.20.11020.2 (or newer

So follow these steps -

1. It says (*Please refer to the ASRock website and make sure the CPU is supported by the old BIOS version) so make sure you start with your original Ryzen 5 1400.

2. Download BIOS v4.80 for your MB @ https://www.asrock.com/mb/amd/x370%20killer%20sliac/index.asp#BIOS Extract and copy X370KLA4.80 to USB flash drive. Restart, go into BIOS and use Instant Flash to downgrade to v4.80

3. Now, download and install your chipset and VGA drivers. I don't see an All in One package, so download both https://download.asrock.com/Drivers/AMD/CPU/Chipset(v2.11.26.106).zip and https://download.asrock.com/Drivers/AMD/VGA/AMD_VGA(v20.45.36_WHQL).zip

*Above links are for Windows 10 64bit

4. Reboot to Windows and confirm.

5. Your chipset and VGA drivers are now updated for the new CPU, so download the latest BIOS https://download.asrock.com/BIOS/AM4/X370%20Killer%20SLIac(6.00)ROM.zip extract and copy to flash drive.

6. Swap the Ryzen 5 1400 with the new Ryzen 7 3700X

7. Insert your USB flash drive with the new BIOS v6.00 and use Instant Flash to update

I hope this helps and works for you!

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

FINALLY FOUND A FIX!! I was helped in this post

I removed both sticks of RAM and then installed only one. The PC booted up as it normally does but now with a new CPU! Not sure why this happened, both sticks of RAM worked with the old CPU. Now I need to figure out how to get the machine to run with both sticks of RAM!

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

Interesting, are they in the right slots? Maybe a ram training thing, is xmp off?

If you are able to boot with one RAM Stick but not two does indicate that RAM is not compatible with your new processor.

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

to get it to run on both sticks manually set the RAM voltage to 1.350 or....1.400 should boot two sticks up just fine ....i have the same issue with my 1800x system any ram i try and it dont matter the clock speed seems to like the ram at 1.35 for anything up to 3000 mhz and 1.4 volts up to 3600 mhz....even got some running 1.4 volts at 3822 in my 3950x rig

Re: PC Stuck in a Cycle of Turning Off and On After Installing New CPU

I was able to get the PC to boot and run with both sticks when I enabled an XMP profile (1.35v, 3200)  in BIOS! I think they needed a higher voltage to run properly. So I can get 16Gb(2x8Gb) of RAM running on my PC now.


I also purchased 32Gb(2x16Gb) of the same brand and speed of the ones that work. However when I try and replace the 8Gb sticks with the 16Gb sticks, it goes back to turning on and off. I think it is resetting the XMP profile because when I reinstalled just an 8Gb stick, I boot into bios and it has been reset.


How can I ensure the correct XMP profile for the 32Gb of RAM when I can't get to the BIOS with them installed?
