SOME RYZEN 7 1700 OVERCLOCKING!

[LtMatt]

I get thousands lower under Ryzen balanced.

Something has to be wrong there to produce that much difference. Using 17.10 Chipset drivers?

My final stable overclock

1700 @ 4.0ghz @1.42v - 71c load - I could get this lower but I like silent fans.
Asus Prime Pro X370
Avexir 32gb 2400mhz
Coolermaster 240 AIO cooler.

Pretty much exactly the same as me when had that board.

Though my temps were mid to low 60's

Just upped to the crosshair for faster 64gb ram support

64gb nice, do you do Premiere 4K editing?

I will be.

Just using elements though

I have found a curious stability issue that I would be interested to see if others can replicate.

When testing stability I can get my system to pass several hours of IBT/prime95/OCCT/RB. Happy that I have a stable OC I then run a few benchmarks. Everything is fine until I run PCMark 8 where it freezes every time. If run at stock it passes every time. Experimenting further I find that at higher vcore levels it fails, or at a lower vcore without LLC.

For example: 3825Mhz at 1.38750V passes PCMark8, 3825Mhz at 1.4V fails. All other stability tests pass at both vcore levels. At 3850Mhz in need 1.45v to pass normal stability tests, but it fails PCMark 8.

To replicate use PCMark 8 basic edition, "run conventional" - the test will freeze the system when running one of the three passes in the home / photo editing section - changing bright/contrast levels on the foliage. https://www.futuremark.com/benchmarks/pcmark8

Now you might think this is just an aberration for a single R1700, but unhappy with the silicon lottery I did spin the wheel twice. My second R1700 can clock higher while avoiding this issue, but it still does suffer (3.7Ghz safe on original, 3.825Ghz on current). System is Taichi x370, 32GB HyperX 2400/C15 OC to 2666/C16 (Issue occurs with and without mem OC). Tdie doesn't exceed 65C.

It seems that conventional stress testing may be OK for testing the system under load, but perhaps this doesn't fully exercise other aspects that can fail when OCing - perhaps such as rapid dynamic clock/vcore changes that this particular test triggers?

I would be interested if other people can replicate this test on their setups. 2 CPUs on a single mobo/mem combo isn't exactly a good sample to draw conclusions from. If others can replicate this issue then at least we have found a straightforward easily repeatable test for a particular type of OC instability on Ryzen.

Test completed. No issues, http://www.3dmark.com/pcm8/19719934

looking for a piece of advice please
I've built my mate a ryzen 1700 machine on a Taichi board with 32 gig of ram but seems to be crashing a bit getting BSOD and google chrome crashing a fair bit too ?


Looks like it might be a Ram issue even though it's showing the full 32gig on the system

This is his Ram set up :-

Was toying to reset the ram to auto in the bios ?

Any advice please?

Thank you

Well, if it's crashing, yes yes the first thing you want to do is reset to defaults.

If it's still crashing try setting the soc voltage to 1.1v

If still a problem, come back. If stable then either bad ram clock or bad ram

Edit: Typed that in a rush as was in bath.

So, if still fails at stock with SOC up, then try running one stick at a time.

If still getting failures after that, may be problem with board.

Proper edit: and still rushing if I edit the quote of myself... go me

Thank you nipping over to his house tomorrow so will do that and see how we go and report back .

worth running a mem test on it as well ?

Thanks

Thanks for that - any chance you would rerun with vcore at say 4.1v? It seems that my low vcore is OK, but higher vcore's (irrespective of the clock) exhibit this issue. Well that's the hypothesis we are trying to test! Which mobo are you using?

Sure I'll run it at 1.4v. Crosshair 6 hero

Same again, no issues.

Anyone finding overclocks are losing stability?

24x7 clocks of [email protected] which was tested very thoroughly is now very quickly (minutes) crashing with IBT runs (same version as before).

I did overnight runs with IBT before! Overnight runs of Prime95 as well.

Software is pretty much identical as well, just have updated chipset drivers since nearly 2 months ago. I even flashed an old motherboard bios to get identical vdroop etc!

edit: Not even stable under 1.300v

I found this and posted a few pages back. Mine passed 3.9 in everything I can throw at it. Now I'm down to 3.8. I can only assume that once the chips have "worn in" they need checking again.

Gonna just double check it isn't the memory.

It wasn't for me but you may find different.

It's only IBT causing issues. I can't be bothered to find what is stable again. I haven't noticed any instability anyway in real use.

If I had to guess it is probably the motherboard. It was run at some stupid heat levels for a long period of time when I was testing stability in march.

This is how I noticed mine, then occt was failing. Then it was crashing loading into windows etc. Yours could be different but it does sound familiar......

Same again, no issues.

Thanks Gavin, appreciate you taking the time to test. The fact that i can replicate this on both R1700s seems to discount the CPU. So either my memory, mobo or something odd with my RX480...

I wonder if I can find someone with a Taichi who can repeat this? I should also test with the new 2.20 BIOS that has just been released.

BTW, I only get PCM8 score of 4690 - and thats with a 1TB 960 evo NVMe drive. Looks like your 1070 and faster memory is favoured by the bench.
