I still don't know why I cannot find Load Line Calibration in my bios no matter where I look.

Any ideas?

Ok based on advice so far, I dialed in 1.34v as cpu voltage with a 0.065v offset. It tends to fluctuate between 1.36 - 1.39v.

I also upped the SOC voltage from default of 0.9 to 1.08 and although I'm running DDR4-2400mhz @ 2400mhz, I upped its voltage from 1.2v to 1.35v

For 24 hours I've been stable.

Is it possible that those memory issues were due to low SOC voltage? I read somewhere that 0.9V is for 2133mhz memory but I had 2400 and it would create bsod's.

But now I'm running aida64 extreme and games and no crashes at all. However last week I was crashing once every 10 minutes.

My hardware all together is this:

Asrock x370 Killer SLI/ac
Ryzen 5 1600 @ 3825 mhz (1.34 vcore with 0.065v offset) & Gammax 400 cooler
G. Skill 32mb DDR4-2400 RAM 

F4-2400C15D-32GFXR

EVGA GTX 1070 Video Card
EVGA 750 G2 Power Supply (upgraded from 500 watt EVGA)
Western Digital Blue 256 MB M.2 Drive primary
Western Digital Blue 4 GB storage drive
Fractal R5 case

Jyacu, please list out the hardware of your system.


For me, please capture the opening Main BIOS page and post it here. Also, snap a pic of the silkscreening on the motherboard showing X370 Killer SLI/ac .

Hmm I'll try downclocking the cpu but even at stock I was getting bsod's. (These bsod's are not like random shutdowns due to overclock).

p.s. I saw your bios and am trying your settings with another offset voltage increase to SOC since I had it at stock before. It hasn't given me a bsod since... but I'll know more the longer it stays stable.

I set CPU to 1.35 voltage and a  0.65v offset.

Please try to be clear with your voltage settings. 1.35 + 0.65 offset is 2 volts, I think you wrote bad numbers again becasue at that voltage your CPU will be died by now.

Max recommended for Ryzen is 1.4v for 24/07 usage.

Anyway, adding OC and voltage changes only will add confussion to your BSOD problem. I suggest to set frequency as manual, but leave stock value for both frequency and vcore, add only the first step on offset and test the system.

Also, leave memory at default for now until you are BSOD free and can isolate the problem from the CPU.

Edit: Regarding the other questions..

I currently have 3825 @ 1.392v. I'm using CPU-Z and HWMon and Ryzen overclocking tool.

The voltage seems to fluctuate between 1.360 and 1.392 (which is why I was looking for Load Line Control utility but still haven't been able to find it).

Currently in my bios I have the following settings. 

https://ibb.co/kq0ZeF

https://ibb.co/ci8bta

1.23125 base with a 1.3 v offset.

I don't have anything under PState and I still can't find Load Line Calibration in the settings as you can see.

Could you give me options/ guidance to have a stable 3.8 ghz overclock? 

I generally stuck with Gigabyte motherboards in the past and this is my first ASRock so I'm a bit confused by some of the settings.


Your screenshot shows the Offset voltage as +130mV, which is Milli-volts, or 0.130V.

That is the voltage added to, or offset from (+/-) the base VCore, in your case 1.23125V. So your actual VCore is 1.36125V. I was not sure what you meant by a 1.30V offset. If that was the true +offset (1300mV), you would be at 2.53125 volts, and have a dead CPU, if you could add that much offset.

Otherwise, the way Offset voltage works is standard, a base VCore +/- the Offset voltage.

Why you don't have the same VCore options that I do, I'm not sure. It may be the 3.20 UEFI version, or that you are using a Ryzen 1600. As I'm still using 3.00, I'll change to 3.20 later today and see what I get. I'm using a 1700X.

Your OC to 3800 from the max Turbo clock of your CPU, 3600, would be reasonable for an Intel processor, but Ryzen CPUs don't OC much above their max Turbo clock. I'm only at ~100MHz above my processor's max Turbo of 3800MHz. So if your CPU can reach 3.8GHz remains to be seen. But you will definitely need more VCore than 1.36V.

Take your OC down to 3725 with the current voltage and see what happens. Or increase the Offset to 150mV - 160mV and see what happens with the BSODs.

What CPU cooler are you using? What is the CPU temperature, the Tdie if you see that shown in your monitoring program.

What are you using to check VCore in Windows? What VCore do you see in Windows?

guys i also typed out the first reply regarding the volts

but he states in the first post he's getting bsod on stock settings as well

hence why ive suggested other options

SAY WHAT??????????

Turn it off and reset the CMOS.

1.3v Offset? Bwhahahahaha You're lucky it's not a fireball.

When I bought this board, I was quite happy but over the last 2 months I keep on getting bsod's.

They all have the following codes:

SYSTEM_SERVICE_EXCEPTION
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
PAGE_FAULT_IN_NONPAGED_AREA
MEMORY_MANAGEMENT

I've upgraded my power supply to a 750 watt EVGA G2 since I thought it was originally the cpu was not getting enough voltage for a stable overclock. But even at stock I get BSOD's.

I thought it might be memory to blame but strangely enough.. when I ran memtest when overclocked, I got a few errors. When I ran memtest at stock.. 13 rounds, no errors.

My memory is 

F4-2400C15D-32GFXR

Which is on the QVL list.

I've noticed the 3.20 bios has reduced my BSOD's but not been able to eliminate it.

And I've also noticed whatever I dial into bios as an overclock.. the actual speed always shows as 25 mhz less.. for example.. 3825 will show as 3791, 3850 will show as 3816 and so and so on unless I use 3825 and 1.23125 volts with a +1.30 voltage offset.

I've run out of ideas how to solve my stability problems so any and all suggestions are welcome.

P.S. I know my board has LLC in some bios that I've seen but I cannot locate it my bios. How do I get to LLC settings?


I have the same board with a Ryzen 1700X at 3.9GHz, VCore 1.35V + 0.00625 offset voltage, G.SKILL FlareX 16GB at 3066. I do not get any BSODs, except when testing memory over clocks at 3200. At 2933 or 3066 the PC is stable.

What version of Windows are you using? What AMD chipset driver version are you using?

First the slight variation in CPU clock speed is caused by small variations in the BCLK. Instead of being locked at exactly 100.0MHz, the BCLK wanders slightly, from ~99.5MHz to 100.5MHz. This slight difference in the BCLK is not unusual in board's whose UEFI/BIOS does not have a BCLK setting, and our's does not. Mine does the same thing, so I set my 3900MHz OC to 3925MHz, as you do. If the monitoring program you use in Windows showed the BCLK, you'd see the slight variation.

No idea what CPU you are using, but your VCore is low for a 3825MHz OC. Is the sum of your VCore and Offset Voltage value equal to 1.30V?

The CPU LLC setting is right below the Offset Voltage setting in the OC Tweaker screen. I'm still on the 3.00 UEFI, but the LLC option has always been in that location. For example:



Do you have the CPU Frequency and Voltage Change option in OC Tweaker on Manual or Auto? Are you PState over clocking, or using OC Tweaker?

I assume you run your memory at 2400, and have it in the A2 and B2 slots? I suggest increasing the DRAM voltage to 1.25V when using 32GB. You may also need to increase the SOC voltage slightly to 0.950V - 1.00V.
