I've owned the x370 K7 for about a year now. I use it with 2x8gb of F4-3200C14-8GVK ram and a ryzen 2700. Since day one, I've had trouble with this board ram combo.
My ultimate goal is to simply use the XMP settings, and overclock the CPU to 4ghz. This has worked, off and on. Using the F31 BIOS, the following settings were stable for around a month: Ram- XMP (3200cl14) CPU- 4ghz (100x40) 1.3875 SOC 1.1 Loadline Turbo/Turbo
Perfect! But a few weeks ago, from a cold boot, I heard the 3 short beeps, the pc boot cycled, and reverted to F25. I updated the BIOS (following all the steps, including EC FW update tool) right up to 53a.
Now I can't overclock my PC at all. The XMP settings still work, but I can't adjust my clock speed or voltage, even when reverting to F31. I have tried everything, including stock multiplier at 1.3875. The PC will restart and run fine, but won't cold boot. I get the 3 beeps, boot cycle, 3 beeps, boot cycle, black screen. I have to manually shutdown and turn back on. PC will then post, but with overclock removed. It still shows the overclock settings in the BIOS, but is running at stock speeds and voltages.
I have had this 3 beep problem since the beginning. I have read a lot about it (including in this thread) and it seems to be a RAM issue. I have been able to use the XMP settings in certain BIOS revisions, but not others. I have tried every BIOS from F20 to F53a. I only get the 3 beeps from a cold boot. My CPU has never been stable over 4ghz, but will run at 4ghz for varying amounts of time, until one day, from a cold boot, I get the 3 beeps. This boot cycling can sometimes cause the BIOS to revert to the backup BIOS, and sometimes it doesn't.
I've tried the following:
Reseating the ram, using different ram slots, and using only one stick
Every BIOS from F20 to F53a
Updating Chipset drivers from both Gigabyte website and AMD website (currently running most recent from AMD website)
Ryzen RAM calculator (have never been able to change any of the RAM timings without 3 beeps, even to 'safe' settings)
Increasing RAM and SOC voltage
Changing CPU overclocking settings (increasing voltage, lowering clock speed, changing loadline calibration)
When working at XMP and 4ghz, I can run Prime95, memtest, cinabench, ect. and have never received any errors. But when I run benchmarking programs, the PC will almost always 3 beep when I restart it, even if I just ran Prime95 blend test for 12 hours with no errors. I never have issues like BSOD's or crashes, and play lots of different games without issue.
Can anybody offer any advice? This has been an issue for a year now, but I could always get it stable for awhile at XMP and 4ghz. Now I can't overclock my CPU at all. I can't even increase the voltage. Thank you for your time reading this. I value any input.
I would suggest two things:
1) Switch the board into single BIOS mode (slide the "SB" switch to the left "2" position). This will disable any of the buggy dualBIOS fail-over or auto-recover stuff and simply allow you to select the active BIOS chip with the "BIOS_SW" switch right above it.
2) Flash your currently selected BIOS chip to F31, then do a full and complete
factory reset, ensuring absolutely no BIOS-related settings are maintained:
--2a) Boot to BIOS and restore defaults, save and exit.
--2b) Shut the system down, switch off PSU and disconnect AC power, and then press the power button for a couple seconds to discharge any residual energy in the PSU capacitors.
--2c) Short the clear CMOS jumper / press and hold the clear CMOS button for ~10 seconds.
--2d) Pop out the CMOS battery and leave it out for a good 10 minutes or more (I often short the CMOS battery socket contacts with something conductive for a few seconds as well for good measure).
--2e) Re-install the CMOS battery, reconnect AC power and switch on the PSU, and then power up the system.
Be patient, and expect that first boot to take a while and that it may restart multiple times during the process. It will be re-doing things like RAM training and whatever other completely fresh first-boot procedures are required.
When it finally boots to BIOS, load defaults, save and exit, then go back into BIOS and establish your previously-working settings (the ones on F31 that had worked consistently for a good while). See if it behaves any better at that point.
