@Da_Techie, - Just had a T740 arrive.
The specifications on the RAM specifically state "Maximum memory speed (3200MHz) is only supported with single-rank SODIMMs".
So I'm on the hunt for 2x32GB single-rank but it seems vendors (Newegg / Microcenter) don't bother to state what the rank is. Looking at the product questions, previous people ask this but often it remains unanswered. Pointers how to proceed welcomed!
I haven't even located 2x16GB single rank yet. Ifdual-rank is used, I assume we have to run at a slower speed, but not clear what speed that might be. The BIOS currently reports:
- 8192 MB DDR4 / Dual Channel
- Memory Speed: 3200 MHz
- Channel A - DIMM-1 4096 MB
- Channel B - DIMM-3 4096 MB
There is nothing in this simple BIOS to even configure anything about that RAM such as a slower speed. So it's not clear if you have to just buy slower RAM or if it will adjust on its own to a slower speed.
