Lenovo Legion 5/5 Pro/7 2021 Discussion

He means the ram. Maybe the alienware cant use the best 3200mhz cl20 timings?

 

Swapped with the HyperX CL20 RAM. There was definitely a difference in performance with the Alienware (110 fps vs 100 fps before) but the change with the Lenovo was a much more dramatic one (145 fps vs 100 fps before).

That is a huge improvement on lenovo. Its getting harder and harder to keep my fingers away from ordering a few sticks..

 

If you compare 'performance' with eachother it's only usefull to us if you describe 'how' you test (settings etc.).
In terms of the RAM it's helpfull if you show the subtimings of each kit (with Zentimings).

 

With Call of Duty Cold War I tested both at native resolutions, ultra settings, motion blur off, rtx off, DLSS off. I know that this shows an advantage to Alienware slightly in terms of fps since at native resolution, the Legion is pushing out 11.1% more render space (1600 vs 1440).

Just trying to go through advantages of each and determine which one I am keeping. It's extremely difficult because they are both great in their own right lol

I don't think an improvement of 100 to 145 can only be put at RAM, some other differences need to occur. That is too big for only RAM. Even the 10% improvement in Alienware is already good.

 

I know, it was extremely wierd, and I swapped out again. Tried on a different map instead of Nuketown. 100 fps with stock RAM (same settings, new map - showroom). Swapped with the HyperX again, 135 fps. So I'm getting consistent results with that game. Division 2 did not have the same impact. Went from 69 fps benchmark to 70 fps benchmark on ultra.

The Legion 5 Pro is going have the better performance due of it using the 140W RTX 3070 while the Alienware uses only the 125W RTX 3070. Personally i think you should stick with the Legion 5 PRO since it'll last longer due to lower temps and easier to clean the fans and repaste the CPU+GPU, and upgrade the components, For the Alienware you would need to remove the entire motherboard in order to do that but the choice is up to you and go with whatever makes you happy!.

 

Thanks for feedback, so it is that game in particular that is heavily affected by RAM.

I concur that Lenovo seems to be the more consistent choice if that is what matter to you.

 

If I noticed that correctly, the Alienware should now support 135 watts via the BIOS update.

 

A really very interesting comparison. I had ordered the Alienware in the same configuration, but unfortunately it has not yet been able to deliver it. I have to say that I was unlucky that the notebook was damaged on delivery and never got to me. Now I have to wait for the subsequent delivery.

Because it was available at relatively short notice, I decided on the Legion 7i with 11800H, 3080 ... which I received last week.

What I also did is swap the RAM and I also opted for the Kingston HyperX Fury (32 GB).

What I have been able to test so far is that the RAM automatically tackles to the 3200mhz and runs at 20,22,22,42.

I still have to test individual games, but what I noticed immediately was that my CPU score in Timespy has risen from around 9500 points to around 11100-11300 points.

sorry, my englisch is not so good, i´m german

 

Weird that your 11800h and 3080 is scoring about the same as the 3070. Perhaps there is an OC feature in your BIOS? Yours should be higher like around the 12k mark.

 

It was only about the CPU score, combined the result with oc on the 3080 was 12841, 11197 cpu-13183 graphics. The 11800h is not overlocked.

 

Could you speak english as the conversation gets ruined if you use another language with few people.

 

Sorry, I will of course try as best I can, thanks for the hint.

 

Ah makes sense (had used google translate before). Ya there tends to be a massive impact to having decent RAM over the crap Lenovo throws in there. I can understand using high density for the Legion 5 Pro line and under, but not the Legion 7!

That was just to test what is possible, the processor was not over-tacked and the RAM upgrade seems to bring something.

 

So I had my laptop on most of the day but internet was down so I didn't really use it much. Well, it's pretty evident that the Legion 5 Pro heat soaks quite a bit, even on idle.
Finally get to play, getting 95 FPS Nuketown (COD Cold War) whereas previously it was 135 FPS. This revelation, right after I sold the Alienware M15 R5 lol

What is the way to choose memory? i am seeing several with less timings but also less frequency

for ex: Kingston 16GB Fury Impact DDR4 SODIMM 2666MHz CL15

 

I have this RAM
Kingston FURY Impact 32GB (2x16GB) 3200MHz DDR4 CL20 Laptop Speicher Kit mit 2 KF432S20IB1K2/32

 

HyperX doesn't cost that much more so I would grab the 32gb set. If you are upgrading memory going from 16gb to another 16gb doesn't do that much. And if you have the amd version 16gb sets usually are single rank memory and would benefit from dual rank set more. Not sure if intel has the same thing..

Edit: https://www.google.com/amp/s/www.tomshardware.com/amp/features/ryzen-5000-mobile-ram-guide

There is a comparison when using lower speed memory with tighter timings vs 3200mhz cl20 memory

 

I have the Legion 5 17.3"(2021) 5800H 3060 2x8Gb , Lenovo says only 16Gb was tested. But i have seen people say 32Gb works and maybe 64, but that is dubious.
My idea is to go to 32Gb

 

Interesting, got a very good score in Cinebench R23 multicore CPU benchmark:

13214 point, superior to any value in Notebookcheck.net.
Biggest value there is 13002 from an Asus.

 

Thats a good score! Is that with new memory?

 

No, stock 16Gb, but i am not sure how much memory matter for Cinebench..
Cinebench R23 is a easy test to make just download it here , https://www.maxon.net/en/downloads/cinebench-r23-downloads

there is not no need to install just decompress, open it and let it run for 10 minutes in multicore without using the computer for anything else.

 

Just curious, if I have external displays hooked up and I close the lid I’m wondering if that negatively affects temps.

Has anyone seen testing regarding that kind of situation?

 

Some heat can dissipates trough HDMI port and via keyboard, but it is minuscule.

 

Never tried Cinebench so I did



and things got toasty

 

Nice Atma, Good results. I did not measured my temps but they were not that high. What was the ambient temperature?

 

About 23c. Think I will try a repaste before too long and see if it matters.

 

My score is very similar to yours

 

Seems Lenovo are the 5800H champions.

Here is the last 5800H that was reviewed, an Acer Nitro only 11942.

#1 again .. for now.

 

Nice

 

FYI, the prebuilt Legion 7i with i7 11800H, RTX 3080, 1TB SSD, 32gb RAM, QHD 165hz, is in stock for shipping by Friday 8/27. Ordered one through my state bar association portal for $2465 including tax and shipping. Some savings for those who don't want or need the i9.

 

Hello again!, I have obtained better results thanks to this tutorial, in case anyone is interested, it is for ryzen 5800h, 4800h, 5600h, 4600h
slightly improved results in cinebench r23 thanks to this tutorial and its author
thanks to this more power options are unlocked

 

How were the temperatures? for me what matter is sustained rendering power.
I think i could have run Cinebench R23 as it is forever at current speed.

 

it went up one more degree 91 °, reaching 3970 MHz before 3940 MHz, in games it seems the same performance, I think the Windows options conflict with the options of the laptop itself, when you touch something and want to leave it as it was, it loses performance ( MHz)

 

Yea it disables turbo boost. Brings down temps but kinda cripples your cpu. I would think it acts as a bottleneck if you have a more powerful gpu. And when you want the extra power you have to fiddle with the options again to turn it on.

How much better results did you get?

 

not exactly, it has several power control modes, there is a disabled mode and it stays around 3300 MHz, in aggressive and aggressive efficient mode it has the turbo boost activated, in games the performance is similar to before, there is a conflict in Windows power options and those of the laptop itself changed them on the fn + q keyboard, sometimes it lowers the frequency when it wants and stays at 3600 MHz, I don't know if anyone has noticed this and it happens to him.

 

Hi gang, so I got myself a Legion 7 with 5800h and 3080 with 16 gigs. Seems I got the good ram but still increased it to 32 G Hyperx. I ran several benchmarks. Does anything look lemonish ?

Also, this is Win10 Home. I'm planning to install a debloated version of Win10 Pro. Can test after that as well.
Btw, has anyone ran into problems dualbooting their Legions with win10 & Ubuntu 20.04 ? Cheers!

 

COuld you run AIDA64 memory benchmark, even the free version?

 

Sure, here are 2

 

Huh, latency is also around 80ns, same as AW x17. Strange.

 

That HyperX memory is CL20 i guess it is not much improvement over CL22

 

10% is not a massive improvment, but the point is that my 2666 HyperX is showing 64ns latency in this test.

 

Your at 2666 should have a much better CL's. That is one question i asked before, what matter more, CL or mhz?

 

Latency is a function of both. It's proportional to CL / frequency.

 

And its an Dell Alienware. You can't have both.

 

Any one have an issue with 3080 oc only able to do 100mhz anything more it locked up
