Owner of Y530, no complain here. Only the bleeding issue and screen suddenly went very dark. Called their support and they immediately replaced the screen the next business day. Added 8GB stick and NVME SSD. Mine is a i5 configuration, I dont really need that much processing power

I've checked my laptop and the Y740 is definitely running on the 80 watt variant of the GTX2080 Max-Q.

Now looking for a 90W VBIOS with the same device ID and rev to flash to the GC.

definitely worth a try but flash at your own risk

I can find the 150 watt RTX2080 Mobile VBIOS from Clevo, can't seem to find the 90 watt Max-Q version.

The big issue isn't the thermal limit, which is 87 celsius, and the Y740 is far away from that, but the Power limit wall that keeps getting hit.

So there's tons more headroom even for a 100 watt card plus the VRMs seem beefy enough.

ok so got my hands into undervolting cpu.

I was able to undervolt to -160mv for cpu core/cache, but it was unstable.
then tried further -150mv for cpu core/cache, much better but had 1 bsod after few hours of playing dota2.

so finally settled for -140mv for cpu core/cache and -50mv for the igpu.

Before undervolt, i was getting thermal throttling occasionally when gaming, the max temps hit 90+ degree C. average temps were in the mid 80s.
After undervolt, no more thermal throttling and max temps when gaming low to mid 80s. average temp was low to mid 70s as well.
all with max fan speed.

so about 10~15 degree C cooler with the undervolt. all done with throttlestop.
the max temps gpu hit is 70 degree C and averages around the 60 range when gaming extensively.
haven't gotten my hands into gpu tuning. do i need to since the max temps is only 70 degree?

oh and another thing, for Speed Shift EPP, i set 128 on battery profile, and 40 for AC profile.
I tried setting it to 1, but the performance gains was negligible but it raised temps up quite a bit.
So i settled for 40 as it was in my TPL min/max range by default 1~40 in throttlestop. no idea why it says 1~40 min/max when it supposedly can change values from 0~255.

anyway the stock dual band wifi card isn't that good.
realtek 8822be..

download speeds was fine, i was able to achieve my max dl speeds for 100mbps line.

where my problem is though, is random disconnects. the kind where your wifi network is still connected but it says "no internet connection".
this could be solve simply by reconnecting to the wifi network..

and its frequency is quite random, can go for days without a problem, sometimes 2~3 hours after using then problem occur.

another one is during gaming, i get massive ping spikes playing dota2, ping gets very very unstable and unplayable. again, occurrence is random. sometimes good sometimes bad.

at first i thought its to do with my stock d-link router from Time.
but after googling on lenovo forums, theres a lot of complaints regarding the realtek 8822be wifi card as well. many users suffer the same problem.

so for now, when at home im connected to LAN already.
for the wifi, i will continue to monitor when outside of home use whether the wifi is at least usable or if its unbearable then i might consider changing to intel 9560 card.

tbh -125mv is already enough

did you encounter noticable uneven core temps?

undervolt GPU too, free performance/thermal boost

I have no such issue with 8822BE

Anyway, can change to Intel 9560 if you want since it's officially supported

what do you mean by this? uneven as in how big the range are from each other?

in hwinfo theres a section with 8 temps right? the first 4 is the cores?

realtek wifi card hit and miss i guess.

a lot ppl seems to have problem with it in lenovo forums.

not specific to y530 only as well.

but compared to them, mine not as severe.
i read others problems are like frequent disconnects and massive ping spike even for web browsing.

yes, temp difference between the hottest and coolest core

if you have 8300H, the thread #0 in HWinfo is the 'real' core

ok so i tested with 2 sessions of dota. each session about 3 hours then i reset the values.

for max temps, the diff between core #0 and #3 is about 6~8 degree, i think max i saw was 10 degree diff between core 0 and core 3.

but for average and current temps all 4 cores are about +- 2~4 degrees from each other..

looks normal...can try repaste...or lap the heatsink like I did haha

Is it very big difference between Y530 screen with 250 nits and 300 nits brightness?

just get the 300 nits.
because not only is it brighter, the colour accuracy is also better.
45% ntsc vs 72% ntsc..

the 250 nits screen is literal rubbish.

^^this, well explained

Thank you xcves and ZM Fong.
In the end, I got Y530 with 300nits and 144Hz screen.
The other configuration are i7-8750H, 2x8GB DDR4, GTX1050Ti and 128GB SSD+1TB.
What is the first thing that I need to do with this laptop?
Must undervolt first?

Check temps first. Then undervolt. If needed then repaste

Why don't get your own RAM and SSD since it's cheaper?

This is a ready stock bought from computer shop.
The 8GB RAM was bought at the shop to upgrade to become total 16GB.
128GB SSD + 1TB HDD came initially with the laptop, I actually think of getting 256GB SSD, but the computer guy advised me not to because scared will affect the laptop warranty.

not true.

warranty will NOT be affected.

and if you replace the part, the warranty will still be there, just follow warranty from the new part's manufacturer.

those are user replaceable components la. they wont void your warranty for doing exactly what its supposed to do.

user replaceable.
