I'm pretty new to overclocking, and I wanted to try my hand at it with my latest build. Now I've messed with the memory enough, though I'm never satisfied with the CPU. Currently I have my R7 1700 situated on an Asrock X370 Fatal1ty K4 board, and the OC is 3.85 Ghz @ 1.408 volts (as recorded by CPUID hardware monitor) on the core. I have the LLC at 4, the offsets are left to auto as I have a hard time messing with them. My core temperatures are well with in reason and I never see them go above 60 C in heavy use, unless in extreme cases for stress test and stability. Any info or advice is much appreciated.


EDIT:
Sorry for the lack of specifications in their fullest, but hopefully here they are;
CPU+CPU Cooler: R7 1700 w/ MasterLiquid 240L
Motherboard: Asrock X370 Fatal1ty K4 Gaming
Memory: G.SKILL Ripjaws V 2x8GB
SSD: PNY 960GB SATA SSD (Boot Drive)
HDD: 2TB Seagate Barracuda
GPU: EVGA FTW2 ICX GTX 1080
PSU: Seasonic G series 750 watt Gold
Chassis: Silverstone Redline Tempered Glass
OS: Windows 10 64-bit Home

Ah okay, thats a lot clearer.

Fisrtly OC with Ryzen master is not the right way to go. It totally overolts, which is why the core voltage is at 1.4+ You want it as low as possible.

The second thing, and this is quite important. You have not been stress testing, which means there will be instability. You are using benchmarking software as a stress, and although the temps will go up, by not properly stressing you won't know what your true temps are and how to gauge your OC, and how far you can push the CPU.

Your mobo is fine, and is a decent OC, better than mine. Don't see that as the issue.

What you should do is set your system to stock (no overclock) run Prime 95 on small ffts (this will only test the CPU, and give you max volate...
List your specs like so:
CPU+CPU Cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

IMHO, you should cross reference the voltages with BIOS, and other apps within OS/GUI to verify if the voltages are consistent. You should try and stay below 1.3v-1.35v within BIOS for 24/7 operation.
 
God, I would not have the voltage that high. YOu should be able to run 3.85 at about 1.3-1.375. 1.4 is too high for that clock.

Also, adjust the LLC down to the first strap. Using level 4 is not advised for that OC. Its only mainly used for extreme OC's which yours is not. It has the effect of combating Vdroop.

What are you using to stress test? Temps at 60 seem specially low, given the high voltage you are using.

Please post a HWmon screenshot of your system at stress with Prime95 or something. But please in the first instance, take the LLC down to the first setting (not auto)

Are you using auto cpu voltage? If you use auto settings it will over volt.

 


I'll see what I can scrounge up in terms of monitoring in the software. It seems that Ryzen Master doesn't want to work for me. I can't even uninstall it. I was just a little afraid to sacrifice to much performance when playing at high resolutions.

I'll fix the specs list, thank you the heads up.
 
@keith12 So should I drop the LLC to 1? Originally I had it on auto and it liked to default at 5. I'll try and get temps posted, right now I'm responding off of mobile, so sorry for the bad responses.
 

Alright sorry about that wait there. So I've just defaulted the BIOS settings and started over again. Now, I can't seem to push the system with in your specified limits of 1.3-1.375 volts at 3.8Ghz. My only two guesses are; that my motherboard is just a poor choice, or that I didn't hit the silicon lottery. I'll bank on the motherboard as I trust what this community has to say.

Now, attempting to run Prim95 with my previous settings mentioned in the original post of mine, I would only get fatal errors for the cores. I've gone back to letting the BIOS take over on the LLC, as I would have done more bad than good, no doubt.

Now in regards to Prime95, I actually never used the stress test with all honesty, I utilized various other tools like Cinebench, Unigene and some other smalls ones. I really only used tools that pertained to what I do, which is sit back, and play games from time to time.

Like I had mentioned, and well like you could've of guessed a mile away, I'm no expert in overclocking. I tried my diligence in research when I had began overclocking not to many days ago, and I found that very few people use this board, and those who do, could careless about the overclocking which is quite funny to me.

EDIT: This is post change on BIOS and settings, excuse me for not stating this.

What you should do is set your system to stock (no overclock) run Prime 95 on small ffts (this will only test the CPU, and give you max volate and temps). Take a screen shot at idle, and at stress (with Prime runnig) then you have a baseline for further OC.

Id suggest setting your vcore manually at about 1.35 and bumping the CPU multiplier to 34 or 36, the test again with Prime on small ffts. If it passes for lets say an hour (i test for 8 hrs or so, so I know it's stable - others will disagree) But for the purpose of getting some baseline results, and a moderate OC without using auto, this is the way to go.

Once you test at a given speed, and there are no error on prime, the you can bump the multi up another level. If you get errors, then adjust the vcore up one notch, and retest. If it passes then you can keep increasing the CPU speed and/or voltage if needed.

Ideally you want to have 3.85ghz with about 1.3.-1.375 voltage, and with as low temps as possible.

If when testing with Prime you hit over 80c, you need to back the voltage or clockspeed off. 80c is okay, but for 24/7 use I like mine lower.

My 1600x is at 3.9 with 1.3 vcore, and max Prime stress temps of 73-75 after 8 hours running. It's stable in my eyes.

If you wish, you can PM me, and I would be happy to give you some help with achieving the OC. Guides like this are useful : https://www.youtube.com/watch?v=17QdDctWzZ8

But I would add that reading and learning about Bios Overclocking for your mobo/cpu combo is advisable.

Yes, drop it to level 1. You don't need more than that for 3.85. If you find you have massive vdroop then you can bump it a notch to level 2 (that's the purpose of LLC to combat Vdroop) Vdroop can cause instability, but you need to be careful with it's use.
 
The issue with llc that high & with cpu voltage offset on auto is that it will wildly overestimate required voltage to maintain stability.

Less of an issue on the older am3/+ socket as power saving features were still available when overclocking & that chipset had the ability to downclock/downvolt at will on lower loads.

With ryzen whatever is set in bios voltage wise will remain a 100% constant irregardless of load or clockspeed.

Meaning as soon as you switch that pc on , up until when you power it off its pumping 1.4v+ through the cpu irregardless of your actual usage.

So yeah , while not inherently dangerous (that boards vrm set is easily enough to soak that voltage up), its most certainly more than you need & could be lowered considerably.

Llc is there to combat vdroop under load , with ryzen you don't need heavy load to show vdroop because as I said before the voktage is constant anyway.
I doubt theres any significant droop on tht board anyway in all honestly but its impossible to tell while you have llc on 4 & voltage offset to auto.

My suggestion would be

Cpu voltage 1.1875v (which is stock)
Cpu voltage offset +.175
LLC level 1
Drop your cpu clock to 3600mhz (for testing)

Boot up & check cpu voltage & stability.

Let us know cpu voltage , ypu should test run with prime , aida64 or intel burntest for 5 minutes or so.

The above should theoretically give you 1.3625v & is pretty much a 100% success rate for a ryzen 1700 at 3.6 (ive hit 4ghz on the same voltage)

If load voltage is less there is some droop there but it's a good starting point to overclock properly & to do it as efficiently & safely as possible.

 
& keithnposted pretty much the same imfo while I was typing on my little 5 inch mobile screen ;-)

Although Ive never been a fan of 8 hour stress tests, for me an hour is honestly enough - the 5 minute suggestion was a temporary one just to check for voltage stability - if its way too low it'll fail in the first 2 minutes generally.
 


Hey thanks man, really appreciate the help! I'll make this weekend a time to sit down and do all of this, and hopefully see some really nice results. Also thank you for the video as a resource. Take it easy my man.
 


I'll make sure to take notes, thank you.
 


no probs, youre welcome :) Have fun!
 


:) I know, responding on mobile devices takes ages :)

Can't disagree with anything you mentioned. For me I go 8 hours, because I want to know for sure (or at least 99.9%) thats it's stable. Also, Ive found that even after an hour, the temps still creep, although much more slowly. But everyone is different when it comes to how long they stress for. I guess the key though is that the OP stresses to begin with. Benchies are good for seeing relative performance, but not as a measure of stability.

have a good one mate!
