3800x thread.

I went for the 3700x rather then the 3800x for two reasons. 1. Price . Being close to £400 meant I probably should just get a 9900k instead considering they dropped in price. 2. The earlier indicator is that the 3700x and 3800x are about 3-5% apart plus Gamers Nexus review of the 3800x.

Hope I don't regret it as I had the money for the upgrade and almost bought the 3800x twice before finally going 3700x.

I'm opposite and have stuck with my 3800X which was shipped today. Same regret my way in that as the BIOS's develop will I see any perf gains. I know all the reviews say nowt difference but they all on x570 early BIOS's. The pains of early adoption eh!?
 
Plonked the 3800X (+ stock cooler) onto my B350M Mortar yesterday and after some initial CPU-Z and games, some basic stats.
Bios CPU fan speed - 20% @ 20c / 40% @ 40c / 60% @ 60c / 80% @ 80c with temps idle @ 40c and with games up to 72c (case is Corsair 280X so airflow isnt the best).
Bios PBO disabled everything else on Auto apart from RAM @1.3v.
No XMP.
CPU-Z single score 544.
CPU-Z MT score 5645.
RAM @ 2933 -14 16 16 (will not do 3200).

Will try and show screeshots later.

Will be getting a Meshify C case, new RAM (Team Group Dark Pro " Edition" 16GB (2x8GB) DDR4 PC4-28800C16 3600MHz Dual Channel Kit - Black) and a new mobo, possibly a B450 TOMAHAWK MAX.
 
@SydDanube indeed. and also b-die isn't all it's cracked up to be (currently).
a trip to the ram sub-forum can show you that it doesn't always "just work"

tl;dr - no need to waste money on ram, spend it on strippers beer instead.

Nice! mines only hitting 548 in Single Thread on CPU-Z but i cant get mine to boost over 4179.xx Mhz in CPU-Z either, dunno why it wont go higher, as CB it sits a lot higher.. Got my ram running at 3733mhz C16 as well as the IF Clock, without any PBO etc, as that just seems to drag performance backwards.

I swear the BIOS is a mess on Zen2 atm, as the chips definitely do not act the way they was advertised to act lol

Definitely some odd things happening with these chips. I am running on a basic board with lower frequency RAM and a stock cooler. Clearly the BIOS updates will favour the newer boards, not sure about the lower boards. We can only hope.
 
Auto OC or Manual OC? what is everyones opinions on getting the most from these chips?

I have mine set to auto on everything in the BIOS, the only thing i have set is mem clock and IF to 3733mhz and Ram is set to 3733mhz C16, ive tried fiddling with the different template settings in Ryzen Master (Default, PBO, Auto OC) and tbh they all seem roughly the same in what you get.

My 3800x seems to hit 4.175 or so during CB15 Multicore, i am wondering if i should just clock everything manually, set manual voltage etc, and an all core OC etc as we all know Zen2 seems to run at default at high voltage.

thoughts?
 
Built mine today, slapped it all together. Changed nowt in BIOS all runs OK so far as I havent tweaked anything yet. Played PUBG and all cores boosting to 4.35 with PBO on (havent worked out where you turn it off yet). Temp graph Sawtoothed between 55-60 Degrees. Did notice CPU1 is in the 80-90% use and the other cores less so. Not even looked at the RAM - dunno what it's even defaulted to.

Framerates in PUBG were much less variable and it felt much smoother.

Try dropping your memory and IF back to 3600 1:1, all on auto, PBO off and Ryzen balanced power plan.
I've found different bios versions do very different things (on mine at least).
 
Not really seeing a reason to go 3800X over the 3700X at the moment, what do you 3800X owners think about it? Of course it could still change a bit with maturity..
 
Yeah according to (probably can't mention them as they sell binned CPUs) the 3800x on average can hit about 100MHz higher, but silicon lottery is still there. It's in their interests to say the 3800x is slightly better silicon as they charge a huge premium. But anyway it'd only equate to a couple of percent extra in performance in gaming so unless you have a 2080ti GPU you're going to better off getting a better GPU with the 3700x. On any normal GPU you're going to be bottlenecked by that in almost all games, not the 3700x.

Exactly how I'm looking at it at the moment, whether this may change with better silicon as time goes by may be interesting but it does seem the 3700X is the sensible buy at the moment, or I suppose if you're not to worried about future proofing for 8 core the 3600 for purely gaming.
 
My 3800X hits the specs as advertised so I have no complaints. I don't game much but when I do it's at 2160p so from that point-of-view I would have been fine with a 3700X or even 3600.

I didn't buy it for gaming though.
 
If you have a look in the memory section of these forums and see all the problems people are having with B-Die and 3700X's, id say one of the extra added features of the 3800X is also a better binned memory controller, AMD bin those too, and as that is now on a separate IO chip on the package, that means that whole IO chip on the 3800X is better than the 3700X.

That's just a guess. As it stands there doesn't seem to be any discernible difference between the 3700x and 3800x.

There are peps on here who have confirmed they are having no issues with memory (3600MHz) and their 3700x.

I really dont think the £50 difference in price justifies 100mhz, I really dont think AMD would even do that, whats the point, why release a 2nd 8 core 16 thread CPU with only 100mhz difference for £50 more, AMD are not really in the habit of ripping people off.
