Two kits of Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 - onto an Asus Prime X370

[FIXXX]

Wondering if the Asus Prime Pro X370 could work with two kits of Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15.

The QVL says only 1 stick and 2 sticks having been approved for 2933 and my kit was XMPed to that.

 

So I wonder what are the constraints to add another kit, since the price is really pretty good.

Perhaps the motherboard would not be stable when trying to maintain 2933 for all four sticks...

Haven't found builds using two kits so asking in case people had similar cases of officially unsupported setups for RAM.

More sticks per channel increases the load on the memory controller, so worst case it doesn't run at rated speed and you need to back off a bit.

 

I was running two mismatched B-die kits at 3000C14 on that mobo with 1700 for benching. 2x8 TridentZ 3000C14, 2x8 HyperX RGB 4000C??

Ye I'm wondering that the RAM may just be limited by the MOBO. But since my workload comes to 13-14 Gigs I may continue with the current setup.

 

How long have you used that mismatched setup? 

 

Back when ryzen was still fresh I had several BSODs and I'm nearly 90% certain it was due to RAM support.

So getting another kit may backfire

 

Perhaps just waiting makes more sense since in 2021 we'll get DDR5 and my workhorse will likely still be going strong then and I might push for more than 3.7 Ghz to make up any slowdowns.

I use 2 kits of G. SKill 3200Mhz 2x8GB.  No issues and runs at 3200.

 

Your motherboard should run it ALL just fine at 3000, if not, RMA that piece of crap.

Long enough to run 3 different y-cruncher benchmarks for hwbot submission. It's only for benching, not a regular use scenario. I actually have 2x4gb 2666 kits in there normally.

 

The longest benchmark was almost 30 minutes, and any instability would have caused it to fail. So I can't say for sure it was 100% stable, but it certainly wasn't obvious unstable.

On your Intel system, which in general handle higher speed ram a LOT better than any current Ryzen.

 

Also in my experience, starting around 3000 is where compatibility problems can begin on Intel or AMD systems. There are a lot of variables, although buying modern ram (kits introduced around the same time as the mobo chipset) generally works a lot better than if you get older modules of similar rating.

Likely when I do feel the need to get another kit - and it doesn't work out - Ill just sell it locally for the same price I got it for. Hopefully there will be someone with reason and logic to realize that the price is much better than local retail.
