As im moving over from Intel to AMD shortly. (The last rig i had was a with a 1090t on the old crosshair formula AM3.
Before that it was a Phenom II 965 on a M4a-79t Deluxe.
Would anyone be interested in compiling a Guide to to Working with the 3900x on the x570 chipset.
Does one already exist?.
Would be grateful for any link to a plethora of knowledge on getting to grips and taming this new monster that will soon be in my grasp.
 
Don't do any multiplier or vcore tinkering ( unless you putting together rendering machine or your app,game is benefiting from it ). Why on earth ppl think locking up their 4.6 chips at lower allcore freq is a good idea , dunno :D it is so 2018 .

It’s cool. I just remember the Hazwell guides for intel CPU’s on Overclock.net and how much of a help they were when I was starting out.
Get what your saying though.

The main problem with the Ryzen is not overclocking. You gain very little from overclocking. The chips nearly give every bit of performance a pc does . Not overclocking exp on newer and code bios which as of writing this is 1.0.03ab version give much better 1-4 core boosts then any overclocking will.

All core boosts up to average 4.15 ghz on my system and I can only get a stable all core oc of 4.3ghz so a avatar of 150mhz all core but less on single to quad core boosts :(

The only thing overclocking gives me is better idle and load temps my cpu is at 4.3ghz all cote at 1.3v stable so my ode temps without the aggressive boosts is in high 40s not 50s.

I would concentrate on cooling advice the 3900x is one beastly monster to tame at times idle temps are high and my all core boost in prime 95 can be within 5 degrees of the idle temp it’s strange but better cooling is a must for this cpu
 
@TrM is it really that difficult to cool? I'm looking to cool mine with a Cryorig H7 and I thought this would be fine as it comes with a stock cooler hence a single fan heatsink is designed to cool it?

I think the very high heat density of 7nm process makes cooling a challenge. My 3700X runs hot on a Mugen PCGH, the 3900X must take some serious cooling.

With how the boost is on stock setting at the moment the voltages are very aggressive and if you don’t do a full core oc like I have the 3900x will use all its thermal limits better cooling = better stock boosting.

It’s a shame really on stock setting I boost to 4.5ghz on a few cores on the latest bios and 4.15 ghz on 12 at stock but I have a custom loop with 360 and 240mm rad on it to keep things cool.

But keeping the chip at stock and investing in a high end cooler maybe a 360mm aio or top Noctua twin tower cooler or be quiet twin tower cooler will give the best out of this chip:)

Whilst the wrath cooler is a good cooler I must admit for a free one it’s amazing but u will hit 85 degrees quickly under stock setting as the chip will keep as high a clock speed till 85 degrees:)

It’s the best advice I can give is to run at stock and invest in high end cooling :) it’s such amazing chip and deserves the best :)

I'm considering cancelling my order, to be honest. Sounds like a thermal nightmare. :(

I think it's just that if you don't have better cooling , it doesn't boost so high. Personally reiterating I wouldn't say it's a nightmare it just doesn't boost so high.

Its not a nightmare to cool under stock conditions it’s actully very easy but if you want the best boost speeds better cooling is needed.

Intel are the same also though a stock i9 9900k will also need top cooling to get top boost speeds and overclocks but it will happy run along on a cheap cooler closer to the base clock speed.

This Ryzen 3000 chips give the best performance out of the box and not much headroom for overclocking and you do need good cooling to get the best out of a 12 core chip sorry but it’s 12 cores :)
 
I've cancelled.

I'll stick with my 2700x for now, and have a look at the 3950x when it releases. The attraction of the 3900x was being able to do a drop in upgrade to my x470-I. Clearly, that's not going to happen.

Probably a good idea as you'd probably be waiting a little while and it will give time for the bios' to be more refined.

Assume some really nice fancy water-cooling for that 3950X.
