AntykainThat DDR4 > DDR5 adapter looks a little goofy.. But, I guess the old saying does apply, "Function over Form". Let's hope we get to a better place in the future where something this adapter is not needed..

TheLostSwedeASUS is working on what could be called a quick fix for the problem, an adapter that would allow DDR5 motherboard owners to put DDR4 memory in their motherboards.

lexluthermiesterWhile this adapter would not be the first of it's kind, it is a bit silly. I just don't see this being released as a full-on product.

InVasManiStill feel like putting M.2's on each side of a adapter along with the DDR memory would be neat. Even if they continued to use DDR5 and bypass the power delivery complications. Basically turn the DIMM slot into a NVDIMM with very short traces to a M.2 that the DDR5 caches. In fact the M.2 would have shorter traces than memory itself which is probably fine being the slower of the two. Since it's Intel platform there is the option of Optane based M.2's as well.

InVasManito a M.2 that the DDR5 caches.

InVasManiI agree seems somewhat unlikely though if they can shrink the height of it and keep cost low they might do a limited run on them.

WirkoSounds plausible?

lexluthermiesterIt does. There are no specs that say they can't do so. This was done with DDR2/DDR3. I can't remember if it was done with DDR3/DDR4, but it would not surprise me.

InVasManiI see your point wouldn't really work w/o wiring PCIE into the DIMM slots in some manner or another. I mean that might eventually be possible to combine the two, but yeah on ADL today.


The memory controller is a mixed channel and width design however which wasn't quite the case in previous hybrid boards. DDR5 is a fair bit different with ADL than other transitions in the past it's as much a complication as big LITTLE itself.

TheLostSwedeI thought I wrote that a bit further down, minus the silly bit.

lexluthermiesterTLDR? I skipped the last few pages..

if it ever enters the market

ST.o.CHThe main issue here is the fact there were only entry level z690 boards with ddr4 and not a single maximus or creator board has ddr4.
Almost all r&d were sent to ddr5 designs.
The same applies to other board makers except evga.
This adapter can be a good idea but in theory, in practical I'm not so sure.

TiggerPretty sure my Rog strix z690-A is not a entry level DDR4 board

ST.o.CHThat´s right, not an entry level,

aQiwhy doesnt Asus make another board with a combo ddr4 and ddr5 solution. Just like back in the days of ddr2 and ddr3 transition stage. The all famous P5QC was there supporting both ddr2 and ddr3 (at a time) solution.

caroline.vWhat about hybrid transition boards? Remember DDR+DDR2 for Intel's 915. At the time if you were going to get a Prescott core chip but already had a high end config with DDR533 memory but an older CPU spending more to grab some DDR2-533 with worse timings wasn't a great idea, but you could wait for a while and get DDR2-667 or 800 when prices were more reasonable without having to swap the mobo again.

TheLostSwedeIntel doesn't allow it.
