ASRock X370 Killer SLI overclocking questions

post #1 of 7
Thread Starter 
Hi guys!

I got the ASRock Killer SLI (non AC version) and have updated my BIOS from version 1.30 to the latest (which is 2.0). I had a few questions which I hope someone could help out with. I haven't done any overclocking since the first generation i7's so I have no clue how things are nowadays lol.


1) Load Line Calibration - I understand what this settings does but I was wondering as to what everyone has theirs set for CPU LLC and VDDCR_SRC LLC?

2) C-States and AMD Cool and Quiet - if my understanding is correct, everyone has these turned off to test stability?

3) CPU Voltage vs VCore Voltage - When I go to OC Tweaker and I set overclock mode from "Auto" to "Manual", two fields appear to change the CPU Frequency and the CPU Voltage. My question is, if I leave the overclock mode set to "Manual" and I change the "CPU Voltage" to whatever voltage I want to set it in, do I then have to change the CPU VCore Voltage to "Auto" or to "Fixed Offset" and change it so it matches the setting in CPU Voltage?


Here's my setup:
CPU: Ryzen 7 1700
CPU HSF: Noctua NH-D14 with AM4 mounting
Mobo: ASRock Killer SLI
RAM: Corsair Vengeance LPX 16GB 3200MHz (currently running at 2933MHz since 3200Mhz does not boot)

Any other input or things I might have missed would be greatly appreciated!

There are many reviews on YouTube channels that overclock the RyZen on the spot and they may be able to help.

I don't have a RyZen setup, but:

LLC: Depending on the board those go up or down and it's to control the vdroop, so not sure if your mobo uses higher or lower numbers for that.
C-Sates: Currently on Intel those are left alone, no longer do you need to turn those off. Hopefully it's the same for RyZen.
CPU voltage and Vcore: Do you mean CPU Core Voltage and CPU Cache Voltage? Maybe RyZen has two different naming schemes for those. The first controls the CPU volts and the second controls the CPU cache volts.

Again, I'm using what I know from an Intel perspective which may not be 100%. YouTube is your friend here.

give me a bit, I have this board and can fill you in

sadly I didn't get time to test which one is more droop - IIRC LLC5 has the most droop/overshoot - so I run mine right now @ 3; I need to do more tests to see which works better

Other than the Extreme Testers - Most people are not touching these, IMO it's dumb. keep them on - make use of them.

this is Asrock being weird; depending on how you want to voltage/overclock is how you do this.
if you want to set voltage at the top for a "mutliplyer + fixed voltage" then do that - if you want "multipler + offset voltage" you will NOT touch the upper voltage setting and use the Fixed offset on the bottom.
if you want to use Pstate0 overclocking - you would ONLY change the voltage on the bottom section "vcore" to offset and use offset (then go to pstate0 - and ONLY CHANGE THE FID)

the offset values follow this pattern :

3 digit #'s : add a 0.00 to the offset to get your offset voltage : EX : 878 is 0.00875
5 digit #'s : add a 0. to the offset to get your offset voltage : EX: 17500 is 0.17500

nearly matches me 100%, I am able to run my chips at 14-14-14-24 2933.

Thanks very much for your input! Do you mind posting some screenshots of your settings on OC Tweaker?

I can get you some this evening EST. my offset will be higher than you should go for right off (as my chip does 1.36x for 3.9 in pstate0)
