M4800 Owner's Thread

Also, to anyone who's upgraded to the WX 4150, or any GPU really, what sized thermal pads should I get?

 

Not at all, difference is minimal. 4940MX has more accurate crystal (chip quality), so can be downvolted more than any other i7. And also has unlocked multipliers. For me it works fine with 42x, 41x, 40x, 40x smoothly with -0.050v on core and cache.

Also, you can make a downgrade from 4940mx to 4910mq via soft (with reducing power from 57W to 47W) and it would be cooler than stock 4910mq.

 

I finally purchased a 4940MX!
It will give me 10% CPU performance boost.

 

So I installed 4940MX CPU to my M4800.
It's working very well. It processes everything super fast.
Also, there's no heat problem.
My M4800's temperature is under 30 degree celsius all the time.

However, at first, the fans were very noisy. I had to go to power settings and change power plan. Now, it's super quiet.

I recommend this upgrade to everyone

 

Hi,
Definitely I'd love to have your modded vbios.
Thanks a lot for the update!

 

Oh ouch, I had to flash the WX 4150 BIOS to rollback to stability which is what it had but now I get Code 43... Thankfully iGPU but now I gotta get it working again.

EDIT: Found my backup VBIOS, flashed back and it's alright now. I noticed with the modded VBIOS was artifacting in a test game of Minecraft with a shader mod, it artifacted and discovered the GPU heated up quite quick... @AlexUnder2010

 

Sad to hear that. I think it is because of ASIC quality. For some reason vendors put low quality chip and selling it as "professional" card. I don't have neither artifact neither overheating neither BSODs, so for me is working well. You could modify vBIOS for your own needs and possibilities of your WX4150 because as you can see chip quality causes issues.

 

ASIC is 56.5% on HwINFO. What's yours?

 

Don't remember exactly but more than 70%. Currently on my M2200 is 81%.

 

That might explain why the one I got was inexpensive... Ouch. New in packaging too when I got it. But I waited for a long time for it to get here. My M2000M in my Zbook is 70%. The card's still doing OK as it is, anyway.
