Legion T7 34IMZ5 - BIOS preventing RAM upgrade

2021-04-12, 22:18 PM

I've been looking into upgrading the RAM on my Legion T7 34IMZ5 desktop to handle some memory-intensive programming projects.

 

Looking into the BIOS options, it looks as if any voltage/XMP profiles have been completely locked/hidden by Lenovo. Based on the forum posts from the past few weeks, I can see that this is a pretty common complaint.

 

This desktop was marketed as a "fully-upgradable, future-proof" PC, and it's incredibly disappointing to see that this is falsely advertised. One of the biggest elements of the gaming/programming/PC enthusiast community these days is the accessibility of upgrading, overclocking, and generally just having more control over the machines that we have paid substantial amounts of money for. 

 

I don't see any reason for Lenovo to have disabled these options in the BIOS, and would urge them to fix this constraint as soon as possible. I certainly won't be purchasing anything else from Lenovo, considering the needless limitations and software hurdles they've placed on the Legion desktops.

Hello @Osteoblasts,

 

Welcome to the Community Forums.

 

The advanced options of the BIOS is intended for developers and technicians only.

You can still access the advanced options however this will require you to modify the BIOS.


Please note that modifying the BIOS may lead to issues with the machine and it would be best to consult warranty before doing so.


Hope this helps.
Regards,
Jack_Lenovo1

Okay, Jack, I'll bite. Please detail the process by which we may modify the BIOS.

 

Thank you.

It looks like the hint is for you to do homework, if you choose. Googling should turn up sites like this:

 

Bios Mods -The Best BIOS Update and Modification Source (bios-mods.com)

 

 

Overclocking is more diminishing returns today though guys, since manufacturers are squeezing out every last drop of performance out of chips. In my mind, voltage increases too often are hard to maintain long-term, unless you stress test for way too long, always thought Any speed increases I want will come from next generation of CPU & GPU. NVMe solid state drive is the fastest and best speed increase I've made over last decade. A true night-and-day difference that is worthwhile. Just saying.

 

Even so, XMP profile should be accessible upon request after a warranty disclaimer, seems to me.

Never mind trawling the dark web looking for bios hacks, LENOVO should provide us a gaming bios that is fully unlocked just like EVERY OTHER SERIOUS gaming desktop manufacturer.

 

There have been far more advances than NVMe that warrant having a fully unlocked bios

Please remind us again who owns these computers, us or Lenovo? Also, Last time I checked Lenovo let's me overclock, and change the voltage of the CPU from within their own software. So tell me again why us lowly pleebs can't manage our own BIOS.

I agree to that, please enable XMP (access), this really cripples this great system.

Or at least give us the option to buy the 3200MHz DDR4 ARMOR memory that is in the spec sheet.
