Hello all,
First time poster here, long time prowler.
I am building a new high-end gaming rig based on the 14900k (coming from two systems, a 5800x and a 10700k). Very experienced with building systems and have been for the last 20 years.
I have seen a ton of posting/videos on DDR5 and issues with Raptor Lake, both with XMP and with more than two dimms populated. It seems the consensus is to only populate two dimms and slowly increment XMP speeds until the system can’t pass a sustained mem test.
That said, I love the look of having all four dimms populated, and my plan was to populate 4x16gb of Corsair Titanium 7200MT/s memory (two sets of this one, specifically). It seems like everyone’s issues have been experienced on 13th gen Raptor Lake, but I haven’t seen much on this topic for Meteor Lake (14th gen).
My questions are, for anyone has had hands-on experience with attempting to get quad dimms working on Raptor Lake: 1) What was your methodology behind trying to get it working? and… 2) Were you successful? If not, what did you end up settling on?
Also, please let me know if anyone has been able to get four dimms functional on 14th gen, and what the specs of the memory you are using.
Obviously when the system is built this week, I’ll make a post of the full build (current value is about ~$6300).
Thanks in advance!
edit: I searched on the PCMR sub and on here for posts within the last two years to see if anything was on this topic specifically with no real success, other than the cases noted above.
You can get four DDR5 sticks working without any issues. However, you will have to significantly reduce the frequency to get it stable.
If you need 64 GB, you should consider getting a 2x32 or 2x48 GB kit, as 2x dual-rank sticks are easier than four sticks.
If it’s purely about looks, they do make “dummy DIMMs” to make a four slot motherboard appear to look fully populated with just two actual sticks of RAM. 2x 32GB + 2x 0GB may be a better option than 4x 16GB to get 64GB.
Also, just in case it’s not clear 14th gen desktop is Raptor Lake refresh. Meteor lake is mobile only. The 14900k is pretty much just a 13900k with a new part number, so anything you see with the 13900k pretty much applies to the 14900k too.
