hi guys

So I think I might have hit the lottery, I built my Asus Tuf-Z390 Pro Gaming last night with a 9700k and Corsair Vengeance 3200mhz.

I started off on 1.27v at 5.0ghz with XMP enabled. I did a series of 3dmark and pcmark benchmarks and an hour of realbench and couldn't get it to crash. I don't do Prime95 etc on my cpus since I believe that is by far the most unrealistic load you can ever acheive on a cpu. And I just can't get myself to torture my system like that. My max temps was 71c during the night. I've always done realbench and through all my years of testing realized that if you can hit an hour on realbench, chances are 99% you won't get a crash ever on those settings. Especially for a gamer, I never do editing or any of those things.

So over the weekend I will see just how low I can go, or perhaps see what vcore I need for 5.2ghz. If it's below 1.35v then I will certainly go for 5.2ghz then. I haven't even started tweaking yet.

It's also the vanilla bios, so first of all I will be updating my bios tonight.
 
Try handbrake, that usually gives the CPU quite a workout. It will also help you tune your AVX offset to more comfortable levels.

Also, I go againast the grain but I would not run a 24/7 overclock at over 1.3v
 
Nice, are those speeds on all cores?


Im still chilled on 4.6 on all cores, and prolly will be for another 6 years.

Yeah it's synced to 5ghz each, I've seen HWmonitor reporting that all cores hit 5.2ghz somewhere during my testing. Which to me is strange since it shouldn't exceed 5.0ghz, updating the bios might fix that.

I was like you myself, my previous system was capped at 1.29v, but I've never heard of failure on cpus after Skylake that ran even 1.4v 24/7. Personally I would stop at 1.32v now.
 
Ive run realbench for hours with no crash just to eventually have a crash when doing work, Ive found that if i am stable with prime95 i am stable, OCCT is also good.

When you say work, do you mean video editing or something? I've played games for hours on end and use realbench to determine game stability. I will never touch Prime!

If I do get a crash eventually I will just up the voltage with 0.01
 
Yes, rendering from premier pro.

That makes sense, that is very intense work, something my pc will never experience. Prime is definitely more adequate for your purposes.

Which I always find weird, because 100% load is not necessarily 100% load, realbench for example utilizes 95-100% load, but the difference is staggering when you compare it to actual stress testing like prime. It's like the monitoring programs doesn't really accurately display the correct load, because 95% shouldn't be a massive difference to 100%. It should be a 5% difference lol.

AVX instruction set is insane, you can disable it in prime95 if you want to use prime without cooking your cpu. OCCT I like because it will stop the stress test most of the time instead of your system crashing, you can also set it to stop when it hits a certain temp.
What does your cinebench R20 scores look like? multi and single.

I'll post tonight when I start tweaking again, I didn't get to Cinebench yet. Do you also have a 9700k?
 
My 9700k I got too 4.7ghz and that's where it sits now.

Never goes over 50degrees under nzxt kraken x62 whilst in games and idles under load around 23 degrees so nice and low

I did get it to 5.0ghz but when I saw 60s and up I chickened out . I know I can get it over 5ghz but maybe another day

But for what I am using it for I am happy where the temps are now.

I got home late last night, and just tried to go 5.2ghz at 1.32v. It didn't last too long, like 5 minutes before it crashed so I decided I would rather see how low I can go on 5.0ghz. So far I went to 1.23v stable. I didn't do too much tweaking after that. I proceeded to reinstall windows because I was still using my old windows 10 from launch rofl.

I will tweak more tomorrow and report my findings.

@Skalas my batch number is L922D758

The thing that irks me a bit, is that my Corsair Vengeance 3200mhz rgb seems to be a bit of a bore. If I drop the timings less than XMP which is 16,16,18,36 @ 3200mhz, I can't get it to boot. Which to me is surprising, I would expect at least 15,15,15,28 at 1/2T. And that's even at 1.35v. So not really sure what the hell is going there, can't win them all hey! Or is there maybe some other setting that will influence my ram timings that I could tweak? I normally just upped the volts to 1.35 and proceed to OC. My ripjaws V 2666mhz for example was rated CL15, I managed 3000mhz at 15,15,15,28 and it booted like a boss. Didn't even bother to push it further. Think I might have downgraded with this set. G.skill from now on.

Are people still overclocking uncore/Nb these days? I see mine is running at 4.3ghz, any use pushing that?

Ah! But I just remembered I am still within my 7 day return on the ram, just logged my return on takealot for a refund.

Ordered these babies instead : G.Skill F4-3600C18D-16GTZN Trident Z Neo 16GB (2x8GB) DDR4-3600MHz CL18 1.35V Black Desktop Memory - Wootware

They advertise it on google as Ryzen 3000 ram, but what would the difference be? On wootware's page they do advertise Z370/Z390 compatibility. I mean DDR4 is DDR4. I bet it's just a marketing term to coin in on the Ryzen hype?

The issue with my set of Corsair Vengeance 3200mhz is obviously the fact that it actually has Hynix chips, and G.Skill Trident Z Neo is Samsung, which is a monumentally better manufacturer of ram as I have learned in the past.

Should've done my research before buying, I am ashamed of myself :LOL:

Corsair memory is a lottery. Check what dram chips you have. If it's Hynix, it wont do much better than XMP.
If it's Samsung b die or micron they can usually be pushed very hard.

If you buy Ballistix they you're guaranteed micron and in rare cases Samsung. They don't use Hynix at all.

Yip it's Hynix alright, I checked last night. I also thought that must be the reason. I'm very happy to return it to Takealot, and will never buy Corsair again. I bet Dominators will probably not be Hynix, but I've never been disappointed by G.Skill.

So I got the G.skill (G.Skill F4-3200C16D-16GTZR TridentZ RGB 16GB (2x8GB) DDR4-3200MHz CL16 1.35V Desktop Memory - Wootware) instead of the one I listed above because that thing had rough timings and it was aimed at Ryzen 3 builds, both of these sets are hynix by the way.

But for some reason clocked a hell lot better than the Corsair ones. I think personally those Corsair ones were faulty because I couldn't even touch the timings without it crashing, and if it did crash it was hard to get the system going again. With the G.Skill tampering with timings was so easy and if it didn't boot, I could just switch off and on again which brought me back to the OC failed bios screen.

It worked for a while at 3200mhz 15-15-15-28, but crashes after a bit, I could up the volts to 1.4v on the ram and it would definitely be stable then. But I decided to go for 16-16-16-34 at 1.35v, since the difference is so negligible and I'm happy with those timings anyway. It's the timings I was aiming for from the start on the Corsair but even at 16-18-18-38 which is its rated XMP profile it was failing memory tests. It was a bad batch!

So here is my 24/7 system, basically cpu @ 5.0ghz at 1.25v, mem @ 3200mhz @ 16-16-16-34, and gpu @ +60 on the core and +400mhz (dual so 800mhz) on the memory.


This will be my system until the 3080 Ti launches. In which case I will just buy that and stick with this setup for like half a decade. Upgrading CPU, mobo and memory has little impact these days :)
