Sir/Ma'am,
 
Good day.  I have finally upgraded my old (very old EVGA motherboard) to the EVGA x299 FTW K (incoming via Amazon)  along with a I9-10980 XE.  Now I obtained a copy of the motherboard manual from the EVGA website and it only shows memory configurations/specifications for Skylake and Kaby Lake CPUs.  Would it be possible to get the configuration chart and specifications for memory for the Cascade Lake CPUs?  I apologize if this is somewhere in the board already, I have looked but didn't find.
 
I hope to use 64 Gb or 32 Gb memory modules but the current chart has it maxed out at 16 gb , but reading threads people have been using at least 32 gb.
 
 
 
Thank you for your time and assistance,
 
-Todd
 
 

Sir/Ma'am,
 
Would you happen to know what the memory limit per module slot is for the Cascade Lake CPUs?
 

Sir/Ma'am,
 
Good day.  Once I get my system set up I will post the results for the memory.  I just didn't want to drop the money for 8 sticks of 32 gb without some additional thought.  More to follow.
 
EVGA- It would be nice to update the manuals  for the less technically inclined like myself.
 
Still an unknown is if we can use 64 Gb modules (keeping in mind the CPU limits).
 
Thank you for your time.

There are some posts here with members trying 32GB modules and having some difficulty, it may be worthwhile to read the past posts for their results.

I have 32GB modules and I have had zero issues once I switched to G.Skill. I had issues when trying to use Corsair.
 
Maximum supported memory by Cascade Lake X is 256 GB. I assume that means when using 8 memory sticks which translates in max 32GB modules.

Unfortunately we have not tested 32GB sticks on the MB however the G.Skill configurator here does show some 32GB packs that they list will work with the motherboard. Since we have not tested them we can't guarantee they will work however G.Skill does recommend it for the board.

To those that are interested: I can't speak on behalf of EVGA, nor do I know how EVGA tests compatibility, but FWIW I have tested two G.Skill 128GB kits (4x32GB, exact part number can be found in my other threads) with three different X299 Dark mbs in following way:
 
10 passes (45 hours worth) of MemTest86 Pro
48 hours of GSAT
24 hours of OCCT large data set (extreme) with SSE instructions 
24 hours of OCCT large data set (extreme) with AVX instructions 
24 hours of OCCT large data set (extreme) with AVX2 instructions 
24 hours of OCCT large data set (extreme) with AVX512 instructions 
24 hours of P95 large data set with SSE instructions 
24 hours of P95 large data set with AVX instructions
24 hours of P95 large data set with AVX2 instructions
24 hours of P95 large data set with AVX512 instructions
 
... and didn't have a single error.
