Often you will BSOD of death before finding your stable settings and may trigger a format of W10 etc - it all becomes time consuming and hassle

Yup or you get settings that seems stable but a random occurrence in a game or something can cause a crash putting you back to square one. And if you're also clocking up the cpu and gpu you've even more to wade through to try and find the cause. Had this issue in battlefield 5 where a mish mash of effects that would only occur occasionally would cause a crash with certain clocked gpu settings.

So CPU turned up, set new RAM (Patriot Viper RGB 3600Mhz) to XMP Profile which is 3600MHz @ 18-19-19-39-68. Gave Cinebench R20 a whirl and got these results:

Does this look about right? Currently got the chip running on my EVGA CLC240 which is probably holding it back. Got my new NZXT Kraken Z73 360mm coming tomorrow so it might hold higher clocks?

Mine at stock with 3600 xmp profile gets:

That is with 16 16 16 36 timing on the ram tho and also fully underwater (cpu, gpu and 2 radiators).

Oddly enough, my CPU hits 4150 when I disable the XMP profile on the ram and run it at 3200 which yields better Cinebench scores.

Mine scores a smidge above 7000, so I'm thinking it's within normal expectations.

Looks to be within the margin that stock 3900X's normally score. I just dug out one of my original CB R20 runs when I had a 3900X back at launch, it scored ~7100.

New cooler might help although I would be surprised if it was being held back to any noticeable degree by the 240mm AIO.

Tried a 4.45 GHz all core OC @ 1.33v and it peaks at about 75c in Cinebench, scores 7840. I've done a few runs and had zero crashes. Games run with a slightly faster frame rate and temps are low 60c. I might have more of a play with it when my 360mm AIO arrives later today. I guess I don't have a totally crap chip which is nice as my 2700X was pretty crap.

That's one of the best 3900X's I've heard of then

Back at launch the silicon was struggling to do 4.3GHZ all cores.

I don't know if there is much more testing to confirm it's 100% stable for my use. I kinda put some synthetic loads on it and then use it as I would normally. I did hear that newer chips clock a lot better than older ones, possibly why they are charging extra for the 3900XT!?

EDIT: Just exported one of my 4K Drone videos in Premiere Pro, maxed out at about 70c but it got it done much quicker than my 2700X.

I got the power over the 142w limit, it didn't make a huge difference in performance but it adds up. Check my settings under 09a to 09d. I realise that manual overclock is superior, but I will just leave it like that while I get from 3733MT/s to 3800MT/s. I've already tidied up my DRAM calculator settings so it might work when I change the memory, and Fclk or is it Uclk (1 needs to be locked to the other's speed) to 1900Mhz. I am around 1099mV for SoC dynamic vcore and haven't changed my timings from 3666MT/s safe yet.

I was watching the Patriot Viper Steel 4400 kit as Buildzoid recommended them, and I got 2 of the kits when they were ~£133 they are now down again to £136 ex vat from rainforest. 4 dimms give a clk for clk boost over dual channel.

It took longer to update my imgur post than in the bios and test it:

How did you get the power past the 142w limit? No matter what setting I change, flash the bios, use Ryzen master I can't get it above 142w. It's literally the only thing limiting my performance on PBO and it's infuriating. (setting I'm referring to is PPT)

On my Gigabyte x570 look in 2 places ;

AMD CBS / XFR - set it there
AMD OVERCLOCKING (* sp? ) - set it there also

It only does it if both are set on me board, though i haven't actually tested if the 2nd one works solo, but just setting in CBS/XFR deffo does not lift the power limits.

And don't hold your breath, raising the power limit does very little unless you have very good cooling.

Yeah mine doesn't. Even if I set every value the same it stays at 142w.. It's driving me nuts. All the other options work fine.

Hey guys, so i upgraded my entire pc, around march time before the lockdown, i got a ryzen 9 3900X at base clock at 3.80ghz, have a 2080 super graphics card and 16 gigs of ram, im wondering should this cpu do a good job with upcoming games, mainly cyberpunk 2077, i havent tried any overclocking, would it give me a good boost ? or does it shorten the components lifespan ? im thinking maybe i would be better up the ram to say 32 gb and i could sell the 2080 for the upcoming nvidia 3000 series gpus. thanks for any help !!

If you haven't tried any OCing i'd go with Ryzen Master PBO/XFR OC. It might give you a 5% performance improvement. Worst comes to worst it might reduce your CPU life by a 1/4 (literally worst case scenario). But considering most CPU's are designed to last for 10-20 years. You'll be upgrading long before it burns out. If you're just gaming, 32gb is overkill. 16 is the ideal amount atm. I also wouldn't be buying a new GPU if I had a 2080 super. Plus it's a pretty bad time to sell it as everyone is going to be selling them and the price is going to drop through the floor. I stick to a 5 year upgrade cycle only upgrading anything that needs to be upgraded once every 5 years. This at least means I see 2 cycles of new GPU/CPU's so that the performance gains are higher and worth the investment. I'm planning on finishing this 5 year upgrade with a 3000 ampere card or big navi card (whichever is better) replacing my 980ti I bought 6 years ago (it blew up and caught fire last year, running a loaner RX 480).

Subzero85 · 4 Jul 2020 at 13:08

ok, i feel for a 5% boost, i might be better sticking with what i have, game will hopefully still do well at 1440p, it would be a bit mad to upgrade again since march time ?

Definitely a bit mad.

I'm in the same boat as you, recent upgrade to a 3900x, with a 2080 ti.

I'm almost certainly going to update to a new GPU later this year for HDMI 2.1 support (which model I'll decide at the time), but for 4k or 1440p gaming, I've seen no evidence that future CPUs will make a massive difference.

The setting was in AMD CBS (these "unlocks" need to be enabled in the bios to get above 142w, just copy the values from your PBO limits. I used 300w PPT in PBO settings and have 230W in AMD CBS settings, they don't match but 230 PPT (package power target?) is enough).

It doesn't matter what I try it just refuses to cooperate. I've been in contact with Asus support but as you can imagine it's pretty frustrating having to wait 2-4 days for a reply :/.

It's been a while since I've looked into tweaking my memory settings but this is what I've got everything set to at the moment. What would you suggest I adjust?

Ryzen Master screens

DRAM Calculator

megatron · 13 Jul 2020 at 17:54

@arc@css
Google the Techpowerup! guide to Ryzen DRAM overclocking, written by the guy who wrote the DRAM calculator tool. Start with proODT, get memtest86 and make a bootable USB stick. Test only using test #7, if it passes that get into windows and test with TM5 (there are different version, one lasts for > 1 hour other lasts 5min). In my experience I got rid of all my errors using proODT alone. My Patriot Viper Steel 4400 is not "Ryzen certified" like my previous Corsair Vengence Pro RGB M2Z3600c18 was, but once you set proODT right (I was folloing the guide), I only needed to test performance against prior settings. Having said that I'm only @ 3600MT/s but its cl16 with quite tuned other settings:
https://imgur.com/a/vwgPWDF

As I say start with the proODT, follow the guide; use the calculator for reference; if you don't need to touch it things like vtt can be auto. Guide advises settings XMP and limiting/setting the memory clock yourself to start testing.

If you like you can take a look here there are some very knowledgable ram overclockers in this thread (Veil for 1):
https://www.overclock.net/forum/13-...membench-0-8-dram-bench-849.html#post28497992

When I get back to 3800MT/s I'll post there myself.

Going to edit with some of my bookmarks - there are some RAM clocking rules:
