Ryzen 3900X thread

I've come to the same conclusion, very time consuming. Really could do with some software that can test automatically and tell you what to set it at with no user input.

Aye, one day...they may be able to implement something on the motherboard (small RAM in BIOS chip) so the bios can be loaded in there which means you are then free to make changes to the main RAM settings. All that will have to be done under a shell with bootable USB to keep the memory allocation small. I am sure they can do it. Just probably CBA to implement it.

It is basically their testing kit at factory that is scaled down for consumer board
 
If you're not prepared to even try ram overclocking then you limit yourself to Ryzen only kits. I have 2 kits of Patriot viper steel 4400 c19 bDie (32GB total). They run only 2100 and of course xmp @ 4400 won't work. However for the time being U settled for 3600MT/s 16 15 16 32 288. Following the guide @ techpowerup I adjusted far fewer variables than when I blindly followed the Ryzen DRAM calculator values.

I have not touched the settings but with my current bios needing to be upgraded for 5000 series I will have to revisit at least 3600 maybe U will shoot for 3800. I bought the 4x 8GB sticks on the recommendation of Buildzoid, but now another overclocker on YouTube: Lummi has said that you should get the 2x16GB kits for their raw performance uplift & easier overclocking than 4 sticks.

I've had a good play with a Crucial kit 2x16GB but eventually settled on an 8 Pack one at 4 X 8GB 3600MHz C14 XMP. Not cheap but works a treat and saved me so much time. If you enjoy the challenge and want to save some money then overclocking is a good option, I didn't have the patience :p

why buy the 4400? Why not just buy the 3600 ram??? Then you got XMP straight out of the box. And save a bucket of money!
 
Hey guys, hoping to get a straight answer to this as I've seen so much conflicting data over the past few weeks it's starting to make my head spin.

First time in 30 years that i'm going with a non intel CPU, Just purchased a X570 Asus Crosshair VIII Hero Motherboard and got a 3090 on the way soon with a bit of luck.

Which processor from the new range would be the best for gaming? My first assumption was the 5950X but i'm being told it might not be the right choice. Can anyone shed some light on this?

It's almost certainly going to be slightly better for gaming than the lower SKUs, but much more expensive so hopeless value. The 5800X will be very close to the 5950X and at 4k I expect the 5600X will be pretty much the same for ~1/3 the price.

What about the 5900? everyone seems to leave that one out? :)

with how infinity fabric works... it is good to have high frequency ram but its betted to use the headroom to tighten the timings

That doesn’t make much sense to me.

take megatrons example 4400 MHz @C19 and downclocked to 3600 C16. You can get 3600 C16 on E-die that’s half the price of those 4400 b-die

similarly if you got overclock headroom what is the point of it if your FCLK can’t handle it. I get people buying 3600MHz trying to get a bit more out of them. But buying really high speed and down clock doesn’t compute value for me as they are so expensive and you end up with pretty much the same 3600 or 3800 speed bog standard ram anyway - which they are as they are all the same stuff just high speeds are better binned stuff or chips are rated for 1.4V on the packaging.

This is the video which made me buy it. I have had it @ 3800Mhz and it beats my Corsair vengence pro RGB @ 3600 when it was @ 3800. I have it at c16 but I'm using 1.35v. I had it at 1.45 and my mobo overvolts by 0.3v; in the summer it became completely unstable... Now I have a fan on it tracking ambient temperature.

The thing is I've left it alone for a couple of months. Also when I upgraded the bios I had to redo my timings and I followed this guide (and learned a lot, most important setting is the first one in the guide and procODT (most impact on stability especially in RAM not on QVL list):
https://www.techpowerup.com/review/amd-ryzen-memory-tweaking-overclocking-guide/
At the time I couldn't be fussed and just went for a safe setting. This is with 4 dimms but its only come to my attention that 2 x16GB is the superior config (also boards with 2 dimm slots, I got this board with a bundle from OcUK).

So I'm just about to upgrade my bios to F31 agessa 1.1.1.0 with support for 5000 series CPUs. I've just spent a couple of days troubleshooting a Sabrent Rocket 4.0 on a raid OS (solution: use standard NVME controller driver from device manager); and I just feel in the mood to mess with the timings. Maybe if I push for 3800Mhz then I can compare what I get from 5900x, but as I say 2 x 16GB is the way to go and acutally marginally cheaper than 2 2x8GB kits.
This is your reference on 2 x 16GB sticks. This guy is a real overclocker (its my first time spending more than 1min setting ram timings):
https://www.youtube.com/watch?v=f_mUZgqUjR4

As far as 4400 MT/s memory. Its just a number. The chips have been highly binned, so you can choose your own timings and frequency and have quality bDie while doing so.

Also if you actually read the guide I posted above, it give you a significant performance boost in games including min framerate.

Actually I have seen kits from Crucial being sold for ~£500 and I paid £133 and that was before the memory & NAND flash price bubble burst (which is projected to drop in price into 2021). However I think that retailers might put prices up because people may be interested in upgrading their RAM for 5000 series.
 
So I will be going from a Ryzen 1600, to a 3900X /XT
Quite the jump.

Can I get away with using the cooler form the 1600 on the 3900XT?, or should I just go with the 3900X as it comes with a cooler anyway.
My tower has excellent air flow.
I'm just not sure if i'm asking for trouble going with a XT with the little fan from the 1600?

Could you recommend one please? Something that is easy to fit, and wouldn't require a motherboard removal (if any even do)
I'm not after freezing temperatures, Just something that will work.

Thanks, having second thoughts now though as I'm on a B350 board and not sure how stable a 3900X would be under load, gaming and streaming.
Might drop down to a 3700x

Anybody been running a 3900x on a B350 board the last few months/year?

But wouldn't you want a cooler on that aswell
