Summary

Asus board images have found their way online alongside lesser specs and names to distinguish them. Among these, a prominent design choice to include DDR4 slotted and DDR5 slotted dimm selections. (I hesitate to call this a leak given the current state of gaming electronics advertising, controlled leaks, and the general lack of water dripping going on)

 ASUS's Z690 motherboard lineup has leaked out over at EEC and will include at least 16 boards. The lineup was spotted by Komachi (via Videocardz) and shows us what seems to be DDR5 and DDR4 specific motherboards

 

According to the leak, ASUS is working on at least 16 motherboards that would launch under its Z690 series lineup. These include the next-gen ROG Maximus XIV, ROG STRIX, TUF Gaming & the PRIME series products

Strikethroughs above contributed due to aforementioned "not really a leak" comment. Pardon my editorializing.

 

My thoughts

I was a really big fan of some of those specialty motherboards back during baby lake and Skylake, which featured both DDR4 and DDR3 slots on the same board. Though, not as elegant because you could not use both at the same time. 

 

Ideally this keeps people from declaring DDR4 "obsolete" and attaching a negative stigma to using a system with older ram.

Why the fuck do we need 16 boards from a single brand?!

And that's with out 3 other Variant of chipset

ATX, Mini-ATX, Mini-ITX. Some of these will be basically the same board but with the addition of WiFi, and then there's the D4 identifier at the end of the SKU name indicating DDR4 support. Some boards like the Prime Z690-V are listed twice, once for each RAM generation.

 

Combine these and you only really need a handful of base configurations of VRM etc. Create one for each combination and the numbers rack up fast.

 

Then there are the specialty models - the watercooled edition, the ProArt edition with a 10G LAN card etc.

Title threw me, thought it was saying ddr4 and ddr5 support on same board. LOL

I really like this since it will make comparing ddr4 and ddr5 effortless. Really interested to see what the performance difference will be.

Will be interesting to see which boards will actually be made in volume and thus can be purchased. Support of two generations of ram also applied during the previous transition from DDR3 to DDR4, with Skylake supporting both. Then, the outgoing DDR3 supporting boards were rarely seen. Will we see a repeat of this? I do feel that most of the focus will be on DDR5 boards. Why would you go for a cutting edge system and use old ram? About the only reason I can think of for using DDR4 will be for cost reasons. DDR5 will likely be at a premium for quite some time.

 

Perf comparisons between the generations will also be interesting, with quite a few options possible.

JEDEC 3200 vs JEDEC 4800: so +50% on officially supported configuration. Will take some time I think for the ideal 2x to happen.

DDR4 vs DDR5 at same clock: DDR4 would likely have latency timing advantage, but lacks the newer features of DDR5 so will see how it balances out. I suspect DDR5 will have better effective bandwidth and XMP DDR4 might hold on to some latency sensitive use cases.

There's seems to be boards with both generations of RAM for the transition generation

 

I own a board with both ddr2 and ddr3 support, for socket lga775

There's also a couple of boards that support both ddr3(I think ddr3l, not the regular ddr3) and ddr4 during Skylake release too

 

So I'm not too surprised to see this news

There has been boards like that in the past though.

I had an Asrock AMD motherboard that supported 2x DDR2 and 2x DDR3 (obviously you could just use one of them at a time). And when Skylake released there were board with two slots DDR3 and two slots DDR4.

So I was expecting this to be the same case... maybe there will be boards like that.

I forgot that part. The difference of DDR3L was the standard working voltage dropped from 1.35v to 1.20v, which then matches standard DDR4. I don't think running higher voltage DDR3 would be a problem if you really wanted to, in the same way most higher performance DDR4 XMP kits ran at 1.35V also.

Iirc Intel came out and say that it may degrade the imc faster bla bla bla... Which caused some fiasco back in the days

 

But I guess it's fine if everyone is running ddr4 at that voltage anyways

Standard DDR4 and DDR3L both run at 1.2v, so it would seem the IMC was designed around that operating point. 1.35v DDR4 is only commonly found on XMP modules, so something that impacts enthusiasts but not systems for the masses which will use standard ram.

 

I've not looked into it, but my 6700k system built in 2015 recently started crashing. I found by trial and error the only thing that improved it was setting ram speed slower. It was running XMP 3200 fine for many years. That ram is now moved into another system that can use the speed, where it is working fine at 3200. So, I do wonder if the IMC of my 6700k is degrading, or maybe it could be a mobo thing? I'm rather less concerned about the ram voltage, and high VCCSA/VCCIO might be more of an area of concern as a lot of mobos jack them right up when you put high speed modules in them.
