Novice 1700x overclocker requesting help.

post #1 of 17
Thread Starter 
I am a novice overclocker and want to overclock my ryzen 1700x to 3.8ghz with 1.3-1.35V. But i don´t know how to do set the offset Vcore voltage. What does the Vcore SOV do? Is the XMP profile good?

Need some help.[/SIZE]

My specs:

- Ryzen 1700x
- B350 GIGABYTE GAMING 3 (F6)
-2X8GB 3000MHZ CORSAIR VENGEANCE LPX (Timing)? (15-17-17-17-35)?
-H110i LIQUID COOLING
- PSU: SEASONIC 750W M12 EVO.

Here is the gigabyte overclocking guide

https://www.joomag.com/magazine/gigabyte-am4-overclocking-guide/0517370001491902144?short

CPU Vcore is the voltage applied to the CPU cores themselves, typically if under load you get a crash to black screen usually you need more Vcore but there could also be a lack of current causing your Vcore to drop causing the crash.

Vcore SOC is the voltage applied to all the surrounding circuitry in the processor this includes the hyper transport which deals with memory. If you having issues getting your memory to run at speed this voltage will help.

XMP (DOCP) could work and make your life easy but if it does not key in your ram speed and timing manually. You may need to boost your DRAM voltage and SOC to get your memory stable at speed.

Just to give you an idea, these are the voltages I am using for my normal 3.9ghz@3200 overclock on a 1700X.

Vcore 1.3750v
SOC 1.1000v
DRAM 1.4000v

First you want to get your memory running at speed then once memory is at speed and stable then overclock the cpu

Oh Thank you. one more thing can you tell me which is the Vcore stock voltage?. So i know the offset voltage should I apply

Well currently when you manually overclock the Ryzen, the clocks stay there. Meaning if you have a 3.9ghz overclock, even with no load your clock is still 3.9ghz. If your cpu was set to auto, when it has no load your clock will drop to 2.2ghz. In auto mode your core voltage will follow your clock speed, higher clock will mean a higher core voltage and lower means lower, so when your clock is 2.2ghz your core voltage may only be 0.400v, then when you give it 100% load your core may increase to 1.350v.

I have 3 overclock profiles.

4.025@3200 - manual core of 1.475v
3.9@3200 - manual core of 1.375v
Auto@3200 - offset core +0.025

For all my cpu overclock I am using a manual core because until (if) AMD updates and allows a manual overclock to drop clock speed when not under load, using offset is pointless. I do however use an offset on my auto profile, not because the cpu cores need the extra voltage but rather it is helping make my memory overclock to 3200 stable. So when my my core clock drops to 2.2ghz with no load my core voltage would be say 0.425v instead of 0.400v with the sole purpose of keeping my memory overclock stable.

I am not so sure there is a "stock" Vcore voltage cause every cpu will have different characteristics. But if I had to give a number I would say around 1.300v. You can typically tell what your cpu likes for Vcore by watching your core voltage has your cpu works. and using the average.

I appreciate your help! May be you re right about that the offset is pointless but one of the differences btw b350 and x370 is that you cannot manually adjust the voltage for the vcore, only by setting an off set. One more thing, at the beggining you told to me to try to oc my ram first but everytime i change something on the bios it constantly reboot.

I usually changed the subtiming 15-17-17-17-35 and the voltage to 1.3-1.35, and tried with diferents @mhz and nothing.

(Sorry 4 potato english)doh.gif

Try this.

Leave cpu clock on auto.
Give a +0.0500 offset to Vcore
Set SOC to 1.1000v
Set DRAM voltage to 1.4000v
Set memory timings to 16-18-18-18-38
Set ram frequency to 2133

Restart a few times back into bios to train. Boot into Windows. Reboot back into bios and change memory speed to 2400 repeat booting to bios to train at new freq (if it will). Boot to windows.

Try next step of 2666 with reboots then try 2933.

See how far you get. Let us know. There is more we can do but I'll have to look at what your board is capable of.

The label says 1.35v and 15-17-17, is it safe to set such timing and voltage? and also the SOC voltage is set by offset too so should I set +0.0500?
Sorry to bother you drunken.gif
post #9 of 17
Yes voltage will be safe and timings will be safe also. You should be able to see in the bios what the SOC voltage is, if voltage is 0.850v then to achieve 1.1000v you need an offset of +0.250v.

Using the voltage to get it to run at the speed you want, once it is running you can reduce voltage in small steps until it begins to fail stress tests, then you know the voltage it wants.

I´m starting to suspect that my bios is not showing me the right cpu voltage but at least, the pc could reach the bios and didnt reboot contantly
