does mobo support a ram which isn't on it's qvl list?

[EzioWar]

Hi, will ASRock B650M HDV/M.2 support this ram Acer Predator Vesta II RGB DDR5 32GB (16GBx2) 6000MHz Desktop Ram (Black) (mdcomputers.in) ? the ram is not on the mobo's qvl list.

Nobodys explained qvl's to ya, i guess?!!?! QVL's are pretty much worthless cause they only contain a brand or two and a few variants. All that means is that they got a couple samples at those speeds/voltages/timings and it booted to desktop without crashs. At one time they were more robust, but today they are useless. As long as you have the correct ddr generation and youre not flying too far from the mobo/cpu memory recommendations they will work, even if you have to fine tune them a bit yourself. Manual adjustment of sticks is always preferred over xmp cause xmp/docp usually will overvolt your sticks to death.

I'd be surprised if it didn't work. QVLs aren't made exhaustively and are rarely updated after the board is released, so there are plenty of kits that will work on that board that aren't on the QVL. It's much more likely that the kit just wasn't tested on that board than it is that the kit doesn't work. 

 

Granted, I haven't personally tried it so I can't guarantee it working 100%, but I haven't heard too many stories about RAM sticks actually being incompatible on a given motherboard for DDR5 (at least with good bins like 6000 CL30 that you're looking at, there's some weirdness that can show up in the worse bins like 5600 CL40). It was a bit of a thing on DDR4, especially in the early days of Ryzen, but nowadays, most RAM kits just use parts from SK Hynix and one of a couple OEM PCBs with the manufacturer just adding their own heat spreaders.

Manufacturers do actually test the stability of the motherboards with an XMP/EXPO profile pretty thoroughly, though granted they tend to do the testing with the top bin CPU they have in the factory rather than something more representative of what you'd actually get.

No? XMP/DOCP/EXPO will load relatively normal voltages, whatever the memory kit is rated for. Sometimes motherboards will load wacky voltages for other parts of the CPU when you enable XMP, that can cause damage overtime, but that would happen regardless of whether you entered the memory settings manually or not. If XMP actually killed memory sticks, odds are there will have been a class action or two by now.

The QVL exists more for system integrators than it does the public. It's a way of saying, if you buy X ram with this motherboard it will run at X speed 99% of the time... 

 

It's not supposed to be an exhaustive list of every RAM kit out there. It's a buy this one and it will almost certainly work at the speed rated on the QVL, buying something else will 100% work, just sometimes you won't get the rated speed of the ram for whatever reason, but in the modern world it is rare that you can't get the rated speed unless it's a stupid high clock, like 5000mt/s on DDR4 for example 

 

ALL DDR5 ram will work on your board, but the only guaranteed speed is JEDEC specs, but in practice it's much less of an issue these days than it was in the ddr3 era because the JEDEC specs are much better than back in the day

I do want to put an asterisk on that, since there are times that DDR5 will not work on a given board. The main example I can think of is the 24/48GB DIMMs from Corsair initially on AM5, since those would blue screen on boot up even at 3600 JEDEC for the first few months of their existence before AMD finally released an AGESA that fixed it. 

 

In this case yes, it should work, since this memory kit is a Hynix bin that's very well supported from all board board vendors, and instances of that are fairly rare, but it's not something that you can say ALL memory kit work at all times, because that's just not true.

True, I just meant that, if they have an up to date bios currently all DDR5 currently on the market should work. 

 

But I suppose clarity is important in these things

support - no.

work - more than likely yes.

 

the QVL is a list of parts that the manufacturer tested on the board, and will absolutely 100% guarantee to work.

 

but that doesnt mean that anything that wasnt tested doesnt work, since computer components are extremely standardized these days it's rare to find a combination of ram stick and motherboard that doesnt work, and even then it's usually a matter of just grabbing one speed lower on the list of profiles.

what.. are you even on about? XMP/DOCP is a method for the ram stick to tell the motherboard what it wants to run at. it literally exists so novice computer builders dont blow up their ram with punching in the wrong settings.
