Legion 7i memory

Hey everyone!

 

So I'm looking into changing out the RAM on my i9 Legion 7i.

 

From my understanding, getting XMP to work is a bit scuffed. In JEDEC spec I've found two options:

Kingston Fury Impact 3200MHz CL20 1.2V

Lexar 3200MHz CL19 1.2V

Can't find the full timings on that Lexar model tho.

 

Can I access the advanced BIOS on the latest version (h1cn45ww)? Is XMP easy to activate? Or more of a hassle?

If activating XMP is a good option then I'd be looking into these 3 kits:

Crucial Ballistix BL2K16G32C16S4B 3200MHz CL16 XMP 1.35V

G.Skill Ripjaws F4-3200C18S-16GRS 3200MHz CL18 XMP 1.35V

TeamGroup ZEUS TTZD432G3200HC16F 3200MHz CL16 XMP 1.35V

 

Curious to read what are you guys's opinions on this. Are there many people running XMP?

Thanks

From my understanding the advanced BIOS was never officially released. It only ever was a beta made available to select few people.

There's this Reddit thread on how to access it via a Windows tool.

 

And here's another thread where a user reports it to be working on latest Legion 7i BIOS, ver.h1cn45ww.

 

I have yet to test it though, so take it with a grain of salt. Still waiting on my unit...

 

But it does seem to be a bit scuffed 😅

 

So it's a modified BIOS and not something that was officially released/sanctioned by Lenovo. Try at your own risk.

The program is just a BIOS unlocker-locker.

 

Anyways, bit of a hassle.

 

Looking into the Lexar LD4AS016G-R3200GSST. These appear to be 3200MHz CL19 1.2V JEDEC, but can't find much info on them... Not even full timings.
