Hello, i was wondering if i can upgrade from Ramaxel RMUA5110ME78HAF-2666 1x8GB to like Corsair Vengeance DDR4 16GB-2666mhZ
on a Lenovo 90JL009WMW, or if i really need to use Crucial's 2x8GB? and does it depends if it is dimm or udimm? doesn't know the diffrent and doesn't know what to get for this board

Greetings and welcome new Lenovo forum user from Spain,
It is better to have two identical sticks of RAM to provide grater bandwidth and as to your question about DIMM vs UDIMM they are the same and has to do with registered memory.

Hi, I have just done a similar upgrade (16gb -32 on a t730). you would deffinitely be better off with a matching pair. also a warning: the ram will run at its default setting and lenovos bios does not have the ability to enable an xmp profile to set the new ram at its advertised speed

Legion T530 specs: Intel B360 chipset motherboard do not support CPU or memory overclocking.
" The B360 chipset doesn’t support DDR4 memory overclocking and as such is limited to the maximum frequency supported by the Integrated Memory Controller. This means all Core i5 and Core i7 models can run at up to DDR4-2666, while the Core i3 models are limited to DDR4-2400.
B360 boards do support XMP, but if you use modules with a DDR4-3000 profile as an example, when you load the profile it will load the timings associated with the 3000 spec, but only run at 2666 or 2400 depending on the CPU used. "
Legion T730 specs: Intel Z370 chipset motherboard do support CPU or memory overclocking.
Davidh184, Your RAM should be running at the memory controller's rating of the processor at 2666 MHz?
What RAM did you install?
Oh and Lenovo has used a few other RAM manufacturers as OEM such as Kingston and Hynix among others so Ramaxel is just their current choice.

I used Corsair CMK32GX4M2A2666C16 Vengeance LPX 32 GB (2 x 16 GB) DDR4 2666 MHz. According some others i have spoken to as well as the Lenovo phone support person have said that most enthusiast ram don't have higher JEDEC speeds programmed in it beyond 2133 or 2400 for compatability. If you have any ideas on how to get the full 2666 to run i would be very grateful.

Thanks for the info! still a shame that there is no xmp support on a product that is marketed towards enthusiasts but at least I now understand the reason im not getting the full speed. I will edit my original response to avoid convision

Keep in mind exceeding the Intel CPU memory controller specification when using XMP or in general overclocking will void Intel's warranties as it causes more wear on the processors and than failure.
So Lenovo is not providing XMP support because of that.
