Hello,
I recently acquired a Lenovo Legion T5 (26AMR5), with an AMD Radeon RX 6800xt GPU and a Ryzen 5800 CPU.
These two products can use Smart Access Memory, however I am not able to activate it.
I have searched the BIOS section, but I do not see it.
Any suggestions on how I can get this done?
Many thanks and happy holidays!

If the issue is the motherboard or BIOS, I feel both are easy to deal with (e.g. replacing the motherboard for a cheap B500 series and/or flashing the BIOS).
Any thoughts on where the limitation is? Would you happen to know what custom chipset is in my Legion T5? Would flashing a T7 bios on my T5 create a problem?
Hi PeteEM,
unfortunately we do not know what the limiting factor is, but we know that the chipset of your machine is AMD B550 and that the feature is not supported on the Legion T5, only on the Legion T7. Both your CPU and GPU are supported though, so it only leaves the motherboard and its BIOS in that case.

That should not be possible and if you were able to use the BIOS flash for the T7, that would certainly brick your motherboard :/

Your feedback helps us improve!Hello @PeteEM ,
Welcome to the Community.
This feature would require Re-size bar enabled.
You'd find it under BIOS > Advanced > Re-size bar support.
Checking the BIOS for your Legion T5 (26AMR5) do not show this option so it may likely be not supported unlike the T7 (34IAZ7) that shows this option.

Hi @spidey101 ,
Thanks for welcoming me to the Lenovo Community.
I understand Smart Access Memory (SAM), AMD's trademark for resizable-bar, has the following system requirements:
- A Radeon RX 6000 GPU (I have a RX 6800XT, so this is fine).
- A Ryzen 5000 CPU (I have a 5800, so this is also fine).
- AMD Radeon Software (20.11.2 or newer), which I also have.
- A 500 series AM4 motherboard (unfortunately, I have no clue what board is in my system, as it is a Lenovo custom). Would you know what board is in my model?
- An AGESA BIOS 1.1.0.0 or later (again, the BIOS on my system is Lenovo custom, so I have no clue).
Essentially, as I feel missing out on 10% more performance is a real pity.
My guess is that the motherboard could be the issue, although SAM has been reported to work on AM4 400 chipsets also (unsupported).
If the issue is the motherboard or BIOS, I feel both are easy to deal with (e.g. replacing the motherboard for a cheap B500 series and/or flashing the BIOS).
Any thoughts on where the limitation is? Would you happen to know what custom chipset is in my Legion T5? Would flashing a T7 bios on my T5 create a problem?
Happy holidays!

Hello @PeteEM ,
Following this thread appears that for SAM, this would also be the same.
Replacement board with confirmed option for this surely would allow this feature.

The Limiting factor is Lenovo refuse devote any development time to updating the bios of any system they ship to add new features. so even tho all the hardware is compatible if new features become available to a particular platform such as resize bar, unlike litteraly every other motherboard/system manufacturer post sale support from Lenovo does not exist.
Frankly, it is sad news. Yet poor software support seems to be the only possible explanation on why SAM would not work.
It is clear that all the hardware requirements are met... this is just a software BIOS issue, which I am sure Lenovo's software engineers could easily update.
Given the limited availability of Radeon RX 6000 systems, the "T7 has it" answer makes little sense.
There are NO T7 models available in Switzerland, for many months (even while the RX 6000 series was launched in 2020). The T7 suggestion is not advisable.
The lack of healthy GPU market probably allows this situation to happen.
There is also an environmental angle, as using hardware to its fullest capability increases the length of use, delaying it from becoming electronic-waste.
Would be nice if anyone with influence or a solid network in Lenovo could read this post and find a way to make the BIOS update happen.
I am certain this is no more than 96 hours of software coding/testing, which would go a long way from a marketing angle towards T5 buyers.
Word of mouth would also be extremely positive. Keeping my fingers crossed.
Remember only some T7s have it... Those of us who paid the same price for 10th gen intel T7 (still being sold) don't get bios updates. But the exact same model with the same mother board and an 11th gen chip get the updates.
Your wasting your time on these boards, If I'm honest. Lenovo for whatever reason have made it there stance that pissed off customers is less expensive than offering post sale support and updates. Your only course of action is to get a refund and return it as miss sold and falsly advertised.
It's been explained and demonstrated that there is no real reason for these updates not to be released for months on the T7 threads, and the mods just selectively ignore you.
