Lenovo Legion 5/5 Pro/7 2021 Discussion

Did you run the memory test in performance mode?
My CL22 3200mhz Lexar memory kit has 76,8 ns latency in the same test(and slightly better read speed but this does differ each test) your CL20 RAM should be faster.

As for mhz vs latency for Ryzen mobile Infinity fabric scales best with faster (read higher bandwith) memory so for mobile 3200mhz (fastest available for now) is the best choise.
Latency is a bit more difficult to compare what matters the most is the tRFC subtiming (560 or less and you're good)-> high latency here will be a bottleneck for your CPU.
CL20 or CL22 will not be much of a difference, both are slow in absolute terms, since Ryzen mobile doesn't support memory OC I would advise to get the cheapest kit with lower latency tRFC timing.

 

Hmm.. maybe some kind of registry power hack could help..

 

I have similar setup and it was really great to see what the memory upgrade did. Thanks! You got about 1k more in the cpu score in time spy..
I wonder are there any significant changes in fps when playing.

 

How are your temps?

 

Why do you think tRFC is the primary timing to consider, rather than say CAS latency which is actually involved in data transmission rather than refresh?

So I'm going to be selling my Legion 5 Pro already (just got it 2 weeks ago).
I ended up being able to get the Legion 7 for the same price (except 16GB instead of 32GB) with the same 5800H and 3070. Ordered the 7i as well because I really do want that 11800H as I believe it's a little more future proof with the Windows 11 including DirectStorage and the interface being PCIe Gen 4. The 7i shows as shipping in 4 months though so I figured I would get the 7 and then sell it when the 7i shows up. The only thing I would be downgrading for that is battery life since AMD is far more efficient.

 

I would suggest returning to Lenovo if you are still within 30 days. Far less hassle in case the buyer was not happy with it for some reason.

Here is a fun comparison: The Legion 5 Pro vs Thinkpad T15g Gen 2. The Thinkpad is basically a gaming laptop in a workstation chassis that can take 128GB of ram. The RTX 3070 is 100W + 10W boost, so a little slower than the Legion 5 Pro 3070. Screen is only 60hz FHD but not a big deal as I always hook up to an external WQHD 27 inch 144hz at home and work anyways.

 

Temps are very good

Before repaste, performance mode, everything at default


after repaste with SYY 157 tim, performace mode, temps about the same, 9 more points in cinebench .. yay?

 

It would be nice if AMD made an application to make undervolt the same as intel with intel XTU

 

I was just testing some Time Spy. I blue screened at -.09 but seem fine at -.085

 

Mine is about the same as yours I just can’t over clock my gpu much at all . What is you score for graphic

my old msi gs40 got good results going down 0.160v

 

best I've done so far https://www.3dmark.com/spy/22507308



-.085 undervolt
CPU 50, 47, 47 ,47 ,47 ,47 ,47, 47
PL1 130 W
PL2 145 W
Afterburner +200/+1600

 

Wow I must have gotten a bad gpu I can’t go over 100mhz I’ll try to see what I get with some of the same numbers

Hey guys, currently waiting on my new 7i i7/32gb/3080 and i had a couple of questions that I've compiled thru reading the whole 61 pages behind us.

When I get it, id like to extend longevity on the device by making it as cool as possible - was thinking of going with LM on the cpu/gpu and adding some gc thermal pads (found some GC ultimate's but they are 120x20, any recommendations?) to replace the ssd ones and any other i find under the hood, any suggestions?
Wont change ram since the included 32 seem decent and the performance gains are rather minimal considering the cost of the sticks.
I'm also planning on undervolting and oc 100+ on the 3080 since that's what seems like a good idea. Uninstalling iCUE right away or even clean installing the system as I don't really trust manufacturers install with the bloatware they tend to add, but that's on me.
Since we have 2 nvme slots being Gen4/Gen3, any recommendations on a good gen3 or even gen4 for the second slot - 2Tb is a must.

Thanks in advance!

 

very good score, almost like my overclocked desktop 3070

Are you overclocking in the bios too? Time Spy crashes on me if I O/C bios and afterburner too.

 

I get results not found on both links?

 

I didn’t know you can oc in the bios lol is that set up stock ?

I haven't tried new pads yet. Someone who has says they are all 1mm except for one that is 1.5mm. They used GP-Extreme because they said they compressed better. I've seen people in discord have good results with LM. I'm just not brave enough to try it .. yet.
I don't know about drives. I see a 2tb Samsung 970 Evo Plus for $280 on Amazon.

 

do not reveal results to the public my fault, excuse me
desktop https://www.3dmark.com/spy/21474885
notebook https://www.3dmark.com/spy/21744892

 

I can't remember what stock is in the bios but whatever it is that's what I've been using. I don't understand why you can't get over +100 on the core in Afterburner.

 

When ever I go over 100 it locked up I get a gpu Sicre of 13k it’s the high I can’t get with this system

I've seen other people say the notebook 3080 is like the desktop 3070. That's a good thing. People that have used LM on my same model have gotten 13.5-13.6 in Time Spy.

 

You have the same laptop in my sig?

 

if that I had read in forums it is similar to desktop 3070, this generation did a good job in mobile GPU

 

Thanks for the reply! Currently debating if I should LM or not, I'm down to do it since it does not seem so dangerous if you protect everything around and have steady hands (I'm also a surgeon so I think I got the hands thing down).
Cooling pads are all over the place on the discord, gonna keep digging till i find the right specs - Also read somewhere that the VRM's have no pads on them, can anyone confirm this?
970 evo plus will have to do, unless i can get my hands on a inland performance for 280 which might be overkill since it is gen4 but hey, e16 controller and good price make it an interesting deal.

 

I wouldn't worry about LM so much but I store mine in a case at night standing upright. I've seen some good methods to keep LM in its place so I may get brave as the laptop gets older. I don't remember for certain but I think the VRM's do have pads.

btw .. this is the stock paste. Its fairly good paste and one reason the 7i has good thermals. I ordered some a couple weeks ago just to have around if I need it. I think it takes 3 or 4 weeks to get it. https://www.ebuy7.com/item/631006993629

 

Yes seem like my system freezing a lot when gaming anybine have that issues

I haven't had any problem like that. Check GPU-Z and see what kind of ram is in yours. Some got Micron and some got Samsung. Mine had Samsung.

 

Mine is micron

Micron is mine

I'm just not sure if that could be what is causing your problem or not. I saw some people in discord one day complaining about getting the micron but I was doing something else and didn't pay that much attention.

 

Does it freeze when it's not overclocked? If it does I would propably rma it. It shouldn't freeze if you haven't done any modifications to it.

 

Yes it does it with out of

Received my Legion 7i yesterday, there's a cluster of dust about 4 pixels in size smack in the middle of the screen. Tried suction cup, light tapping, etc., nothing will move it. Lenovo CS is awesome and will send out a new replacement laptop. Hopefully it'll be restocked soon (i7 11800H / 3080 / 1TB prebuilt model). I am thoroughly enjoying this one in the meantime until I have to send it back to them.

I am running a GPU OC of +150/+500 in Afterburner. Also able to undervolt the CPU by -.080 in XTU and set all cores to 4.6ghz.

Timespy: overall 12,805 / graphics 13,037 / CPU 11,633. Pretty great for the 11800H?

Cinebench R23 test from earlier today: 14,273 multicore. Some thermal throttling occurred, so not sure if this counts as a "valid" result.

 

I've been away from games last 7 years tbh. What tools do I need to check temps while playing games or running benchmarks? I've only started playing Witcher3 and while the settings are on high, don't feel excessive heat or fan noise.

 

Also, installed Mint along Win10 as dual boot. First tried Ubuntu but got black screen, something to do with nvidia drivers I assumee. Though, Mint tagged along just fine.

 

You can set up Afterburner to see stats in game. For benchmarking you can use HWMonitor and/or HWInfo.

 

This is the pad placement and thickness in the 7i. Not my photo.

 

I’ve had some of the same issues too it seems like with steam, battlenet and just in general programs hanging up and freezing for a few seconds at a time and then it’ll go back to normal and life continues on LOL.

I’m on the 7i 11800h 32gb 1TB 3080 model. No mods / OC, just 100% stock at the moment. Micron Memory also.

 

I have the same system as you mine freeze and gets stuck I have to hard reboot .. I think I’m gonna RMA


Sent from my iPhone using Tapatalk

 

I’ve had to hard reboot it twice maybe every other time I just give it 5 to 15 seconds to figure itself out and then it snaps back. Let me know if Lenovo has any suggestions or otherwise, I may end up myself also RMAing this unit.

 

Don't use HWMonitor as it polls the CPU in such a way that it causes high usage and improper temperature readings.

 

Holy cow thank you so much. This will make pad changing easier. GC Ultimate here we go!

 

Thanks, I'll stick to HWInfo then. I've noticed HWMonitor gives some erroneous info sometimes.

 

If you notice, there is some red goop just above the CPU heat sink. He said that does not make good contact with the VRM so he scraped it out and used a 1mm thermal pad. You need one that compresses easily though. He said .5mm is too short and the thermalright 1mm is slightly too tall because it doesn't compress much. He is going to use Gelid Extreme 1mm.

 

Just ordered Gelid ultimate pads 1mm and 1.5mm, as soon as i make the change ill report here how it goes with them, as the ultimate's have better thermal conductivity.
Edit: Aktchually just cancelled the 1mm gelid for 1mm fujipoly thermals that are 17 W/mK.

 

I've used those before. Good but expensive.
