Re:Compatible 2933MHz Ram for Legion Tower 5i Desktop?

2020-12-08, 1:56 AM

I'm assuming you purchased 2 32Gig sticks.  Can you tell me which 32Gig sticks you purchased.  I just got this system 3 days ago.  It came with 16Gig.  I'd like to add 2 32Gig sticks.

Thank you!!

Re:Compatible 2933MHz Ram for Legion Tower 5i Desktop?

I purchased 2 Corsair DDR4 32Gig 3200MHz sticks.  After installing them my memory speed slows down from 2933 to 2133.  I'm having the same issue as others in this thread.  Has anyone found a solution to this issue?

 

Thanks!

I am in the same boat, I am very happy with my 90NC004UUS Legion desktop. I bought 32GB of Crucial Ballistix DDR4-3000 (knowing that it would be limited to 2933 because of the i7), installed it but it is now running at 2666 and there are no memory BIOS settings that I can find to bump that up. I assume XMP is disabled on the motherboard due to B460 chipset and it is running at default JEDEC timings (anything above 1.2v is overclocking apparently) but it should be able to be run at 2933.

 

Would be nice to have some sort of official Lenovo answer since we supposedly have super premium legion support (not holding my breath!)

 

EDIT: I think I am SOL since the fastest non-XMP profile on this RAM is 1333 (x2=2666) as shown on HWINFO. It would have to have a non-XMP profile of 1466.5 to be able to run at 2933. I believe that until we can get XMP profiles on this BIOS, we are limited to the JEDEC RAM speed. Which is stupid because the i7 should be able to hit 2933 as advertised. Do not think putting the DIMMs together will fix anything.


Wish I would have known this limitation before purchasing RAM, only flaw with this PC so far. I guess the 3200 OEM RAM that the PC shipped with had a higher JEDEC profile since it was running at 2933. On the other hand, CAS15@2666 is probably faster than JEDEC CAS21@2966 which seems to be the max speed available at 1.2V. Probably does not make much difference in the end but would still be nice to get the performance we paid for by being able to access it in BIOS

@jfprieur  So would a solution be to find RAM with 2933Mhz as a non-xmp profile? How does one check that before purchase?

Will this memory from NewEgg work?

 

Can I add it to the 16 GBs already from Lenovo and now have 48 GBs of memory?  Is the timing compatible with what's installed?
