AMD Zen 3 (5000 Series), rumored 17% IPC gain.

[Grim5]

I'm hoping I can get my 3200 cl14 b die kit to run at 4000

CBA with all this. Think I'll just stick to my decent latency 3200.

I hope reviews show scaling at 3200MHZ and 3600MHZ memory speeds too. It will be useful for people re-using their existing RAM kits.

What? Free performance assuming your RAM is decent. This is Overclockers, not Cantbebothereds.

It should do as I've had my 3200/14 up to 4400 and that's on a B450.

How memory manufacturers must love AMD.
There was a flood of various 3600 speed kits after Zen2 launch. Prepare for 4000 kit invasion.

But seriously, any good 2x16GB kits at that speed that won't tank latency?

There's 2x16 bdie that behaves like any other bdie.

bdie isn't in production anymore Samsung stopped

No.

As owner of dual rank B-die, 4000 speed could be out of reach for most kits. And gskill 2x16 rated above 3733 are quite expensive

 

[Brumboy]

Probably the 8 pack 32gb kits 3600/16 or 3200/14 and overclock them with some extra voltage.

What about this set ? https://www.overclockers.co.uk/team...4000mhz-dual-channel-kit-black-my-098-tg.html

Would that be wise to take advantage if the new CPU's can use 4000mhz efficiently

Absolutely. And for new buyers looking to save some cash.

Haha, touche.

This is my RAM: https://www.overclockers.co.uk/team...-3200mhz-dual-channel-kit-grey-my-0aj-tg.html

Do you think I'd be able to get more than 3200Mhz on it? I haven't bought a CPU yet.

 

[Toasty]

Nice hopefully this is actually true - Buildzoid said that although the IO die was unchanged the actual limit to FCLK was probably the traces on the substrate so they might have improved them.

3200 and 3600 decent price but option available if really want to push.

 

[opethdisciple]

I saw yesterday on a Turkish website they where claiming the FCLK on these chips will do average 2000MHz so a dram frequency of 4000MHz.

Whether that's an average or top end I could be wrong.

Maybe it's the top end considering the IMC is apparently unchanged.

Either way a 200MHz average bump in FCLK is nice.

Here is some confirmation.

 

[Nutella33]

It should do as I've had my 3200/14 up to 4400 and that's on a B450.

What kind of timings did you get with these increases out of interest?

Thanks, I'm new to Ryzen to pretty new to all this fabric clocking lark!

Board optimizations go a long way for DR support. Same kit struggling to stabilize at 4K on a z390 apex is doing 4500 on z490 Apex.

also DR with Rank Interleaving makes up for any speed differences vs SR

currently quad rank per channel, running 4x16GB 3120MHz 13-14-14-34 1T @1.44V.
For next system its DR or bust. #
Yet to get maximum out of it, would be nice to clock it to 4000MHz if that's the new sweet spot. Never mind the timings.

Any tips about B550 motherboards that are better at memory OC? Tomahawk?

Didn't Zen 2 need fast 3600 memory to make up for the latency issue?

I thought the latency issue was fixed in Zen 3?

Intel also benefits from faster RAM, its a thing.
