Lenovo - Legion Tower 5i Gaming Desktop - Intel Core i7-12700 - 16GB Memory - NVIDIA GeForce RTX 3060 - 256GB SSD + 1TB HDD - Black $999.99

I'll try and keep it brief. JEDEC is the across the industry standard "plug and play" specs for RAM. This involves a standard voltage and a certain mhz range that's able to be reached. With DDR4 is rated up to 3200mhz, cas 22, at 1.2v. While I'm not as familiar with DDR5, I believe they are up to 6400mhz at 1.1v.

So the "high performance" ram achieves higher advertised numbers by overclocking - increasing volts - to get those bigger sexier numbers. You could tweak the volt, timings, clocks, of the RAM yourself in BIOS - but they also came up with profiles you can easily select to achieve the same result - which is XMP. Enable XMP in BIOS and BAM, you get those big sexy advertised numbers on your RAM.

Now the problem with Lenovo is that their proprietary mobo locks you out of messing with RAM volt, speed, clock, etc... and they also disable the nifty XMP feature. So now you're stuck with the plug and play JEDEC standard of RAM. Unless you use their compatible RAM selection that "they've tested" and endorsed. And just because you use the same manufacture, series, etc., unless it's a specific line they've sanctioned, then you're stuck with JEDEC performance. And of course their "tested" ram that you can only buy through Lenovo is astronomically priced against the equivalent market.

As an example, my Lenovo Legion 7 desktop came with DDR4 Kingston Hyper X Fury 3200 ram, cas 22, 1.2v - but the caveat is that they have a proprietary Lenovo part number. I can buy non Lenovo Kingston Hyper X Fury 3200 ram and it will only operate at JEDEC 2400mhz - at least the timings would be a bit lower. This is why proprietary pre builds gripe so many people.

Maybe some others here have better insight than me. Just my own personal experience.

My Lenovo Legion T5 28IMB05 used to freeze my computer and I had to restart my PC after 30 minutes of gaming. Also upgrading to Windows 11 seems to cut performance in half. Their driver support is non-existent and the only solution that works is to use an old Nvidia Driver from April 2021. There is even a class action lawsuit.

My mistake. Lenovo naming convention can be confusing.

This model is the DDR5 version which supports more memory and slots.

The older version is DDR4 with limitations.

i have the same 10400 and gtx 1660 PC for 2 years, now playing any game makes it super loud fan even if i set fan speed o quiet mode.

I dont know if the fan issue is the CPU or GPU tho.. thats why looking for a better PC.

I have this PC, got it from Best Buy for the same price on Black Friday. It is DDR5 but I only see 2 slots

Edit: disregard, there are 4, had to squint harder.

Happy to answer any questions anyone might have.

Speaking from 11th gen Intel Lenovo Legion 7 desktop build experience.

Lenovo will use a proprietary mobo as well as proprietary memory. The mobo isn't a huge deal since you're probably not going to replace it but it will host one or two proprietary connections- usually the front audio pins for the case.

Memory is a totally different story. Lenovo WILL NOT enable XMP so you will be stuck buying their overpriced "compatible" ram through them or finding used on eBay. They have different part numbers so nothing is "rebranded. " You will be stuck with JEDEC standards.

My 2 cents - I would not buy the prebuild again. I've built every PC I've owned but I went the Lenovo route during the height of the GPU crisis. Only way I could ever get my hands on a new card. Now that's not an issue. The Lenovo works well, is built nice, and generally seems to be good quality. I just have a major issue with them withholding stock features like XMP.

One question I have is how do I get legal windows pro at a reasonable price for building own pc. I have never figured this out. Thanks to all for insight.

Says it came out September 17, 2020.

What cooling system does it have?

How do you like it?

I see Samsung in the parts list, with Hynix and Micron listed as substitutes. And Crucial (Micron) has a long list of compatible RAM for this SKU.

I'm not experienced with XMP and can see how not supporting this, if accurate, might limit the ability to fully utilize high-performance RAM, but I don't see how this limits RAM choices to what is only available new directly from Lenovo.
