The memory controller is on the CPU.

Sorry, I meant the max supported RAM frequency for the motherboard

I am just glad AMD seems to have caught up in gaming a lot, i need a computer with more RAM, 32gb min, and more cores for the work i do with VMs etc, but i want it to be able to game quite well on the side. The 3900x is looking good based on geekbench etc results, taking the german review with a grain of salt, but even then its way better then 2700x. The real question is RAM, 2vs4 and speed.

The sweet spot appears to be 3600-3733MHz. You can run faster memory but you may get lower performance. The results are unknown on say the B450 boards but check out MSI B450 Tomahawk or Carbon Pro. Probably as good as you'll do for £100.

Oh i will probably go for a board with 3x NVME ssds for the speed tbh, i could use the highspeed storage for some of the VMs.

Hi, hopefully someone can help me find something out.

I've been trying to find a 300/400 series motherboard ~~with a memory controller~~ that can handle DDR4 3600 Mhz RAM or higher, ideally for £100 or less.

If so, what is the name / model number please?

Otherwise, I think I will stick with 3400Mhz RAM.

I've been thinking x570 would be a good option if getting 4000Mhz or higher RAM, as older AM4 motherboards can't support it.

I have an Asus B350F Strix and with Ryzen Gen1+, was able to oc the G.Skill FlareX to 3466 CL14. I have since moved the ram to a X470. For previous Ryzen Gen the quality of ram matters most. It seems Zen2 is not as fuzzy about ram but i would recommend something closer to 3600 MHz speed. CL16 OR 17.

For the motherboard, consider this . . .

Thanks guys, the B450 GAMING PRO CARBON AC looks nice.

I've found some motherboards that support upto DDR4 3533, which I might go for. Maybe the prices will come down soon anyway, when the x570 becomes available.

And the memory support lists should be available for motherboards soon, which I think will be worth looking at.

Just as a slight warning, I just checked the CPU support list for the asrock b450 Pro 4, and it's got the 3800x but, notably, not the 3900x. Might be an oversight, but might also be that not all the CPUs actually work on all the boards even if they have VRMs that should be able to cope.

Asrock has not yet updated 3900X support for any of their boards. None of their X570 boards have 3900X on the supported CPU list either.

There's a review here that claims to be running at DDR4 3600 mhz here, on an ASRock board:

https://www.tomshardware.com/review...g-itx-ac-overclocking-motherboard,5824-2.html

What do you guys think? Is this legit? Officially, the board only supports upto DDR4 3466+.

I did hear that memory clocks can be higher on dual RAM slot boards.

I believe the imc will dictate the ram speed. For Zen2 the ideal is 3600 MHz. Max being 3733 MHz. Any higher the IF will go half speed - 1:2.

The IMC which is part of the cpu, so motherboard wont matter. I also believe that the quality of ram still holds somewhat.

At cas21 I should certainly hope it can do 3600mhz!

i would be very suprised if the top x370 and x470 did not suport the 3950x
i get that the vrm was not allways the best be we are all just guessing how much more the 3900x and 3950x will stress them. My own personal view i think the vrm on x570 is over kill and the better x370/x470 and b450 will be perfect platforms for amd best cpu

if amd was majorly concerned on x370/x470 not being able to handle the extra cores on the new cpu they would have made a whole new socket am4+ or something and compltly locked off the older motherboards for ryzen 9 and make the 3900/3950 as requiring x570

Ofc the VRMs are overkill, for some ridiculous reason it's what we obsess over on motherboards. Hell, buildzoid will spend HOURS talking about the VRMs on a board. And how important they are. :rolleyes:

Truth of the matter is. Unless you are overclocking to the moon on LN2 then they just aren't. Certainly not to the level that they have been put into X570. I mean it's very likely ryzen 3000 will overclock a few hundred Hz at best. So the VRMS are of no concern.

But while people keep obsessing over them and buildzoid and gamers nexus keep going on about them (because they do LN2 overclocking) then we will pay for stuff we don't need.

Question is . . . how much cheaper a X470/X370 motherboard will be a good alternative? I think some are willing to go with a cheap but capable B450 or B350. But if the budget fits the cheapest X570 board, then go with it and probably take advantage of nvme gen 4 speeds.

To be fair, he spends longer talking about how overkill they are on many boards.

According to pcgh the stock 3900x pulls 230w so the vrm is justified. Remember vrm is not built for everyday use exclusively it’s built for overclockers. The 3950x will probably be 260w+ And this is before overclocking

Really? How can you have a brand new X570 board not support new CPUs one day before launch?

Ryzen 3900x

https://browser.geekbench.com/v4/cpu/13776562

Single score 5818 only at 4.35 ghz
Multi score 47798

That's impressive.

Is it though? My 5960X gets 5400 single core at 4.5ghz and that launched in 2014. Also the 4.35ghz suggests to me that's a typical clock speed at load.
The more results I see the more I doubt Zen 2 despite what we all would like to see and are hoping for.

No, but the 65W 3700X for £350 is. Scored 5700 at 4.4GHz. We will see more in the days to come.

Wait the £220 R5 3600 scored about the same 5900. Now, that is impressive. Probably oc'ed to the moon on a X470 motherboard!

The low core parts are clearly better at single core loads.

But why, is the stock cooler not capable of letting the 3900x run at 4.6 and so it downclocks the cpu to 4.3 to prevent temps from getting too high?

We know the 3900x pulls nearly 100w more power under full load than the 2700x yet they use the same air cooler

To be fair that's a $1000 CPU at 2014 prices with 20MB of L3 and 140W TDP. What does it do multicore? Unfortunately I keep seeing all these one dimensional comparisons. As a total package how do they compare?

I'm not taking either side in this as I like to find the truth in any situation. I suspect Ryzen 3000 will have some weaknesses but as a package with AM4 it will be a great choice for a lot of people, not all
