I have found this one, probably eDP

 

I don't think it's an eDP panel. Parts-People have spares of that part, and it's an LVDS panel I'm afraid.

What undervolt settings do you guys use?

[M4980]

Decided to try the Forza Horizon 4 benchmark on ultra settings with my Quadro T1000, pretty impressive results

I only use -35mv, think my 4810MQ is pretty bad. Starts crashing below -50mv if i recall correctly

I haven't undervolted my M4800, maybe one day but I haven't for stability reasons. I could do it though, considering it does get a little toasty on Turboboost...

 

Also on an unrelated note, I might have mitigated the fan rattle/buzz. I took the CPU fan apart and was twisting the plastic casing of it slightly to bend it into a straighter shape. I don't think I need a new fan anytime soon now.

@Vaardu I see that you have a Zbook 15 G2 as well, interesting as they are the most comparable laptops from this generation.. how do you find it compared to the M4800? Any notable pros/cons on the Zbook?😀

There's some pro and cons about it. It might be quite a list, might not but:

 

Pros:

• Thunderbolt 2
• eDP models, none of the LVDS transition to eDP like Dell
• Uses the later NGFF/M.2 format
• More BIOS security on some models, even BIOS recovery
• Doesn't use the rubber coating on the palmrest

Cons:

• Servicing requires more disassembling, even for replacing a fan
• Fewer GPU support (anything newer AMD cards causes the fan to be 100% unlike Nvidia)
• Single fan
• Uses 2260 size drives, harder to find
• MUX with any new "unsupported" GPU results in black screen, always need Hybrid graphics on and secureboot off, might be the same for the M4800)
• Buying a Zbook that came with i5 dual core resulted in 2 memory banks instead of 4, I don't think Dell did this with the M4800 (?)

Initially, the WX-4150 thats in the Dell now was for the Zbook, but discovered a setback with the thermal management. It wouldn't control the fan, resulting in 100% all the time. Now I don't know if it's a result of the VBIOS, because fan control in the Polaris BIOS Editor had flaky looking settings there...

 

NotebookFanControl would've been needed but at the same time it wasn't worth it. I ended up with an M2000M in place of its original K610M. So the WX4150 was flashed with the Dell VBIOS and drivers installed without a hiccup.

 

When I bought the machine, thinking "oh, 8GB RAM, no big deal" since it said on the listing on eBay, I got more than that. I booted to the BIOS and found out it was populated with 24GB RAM and a 4G LTE WWAN card. Needed a new lid and a new heatsink for a GPU upgrade and a new battery too, so it's almost fully upgraded.

Nope, this is a platform limitation from Intel at the time.  Two cores = two SODIMMs max.  Applies to M4800 as well.

 

(You can use "unsupported" GPUs with Optimus disabled, though, as long as the GPU card supports the display type that you are trying to use.)

In my case the M4800 has a 120Hz panel in it and is a little flaky with the BIOS settings if they're defaulted. I have to leave CSM on and SecureBoot off otherwise while it does POST, there's no output until it's in Windows.

There was a similar thing with even "supported" GPU cards in the M4700 & M6700.  I think it depends on vBIOS support.

 

Dell's handling of this was a bit crazy.  M4700/M6700 launched in July 2012, a little bit before Windows 8's release, and they didn't originally have UEFI Secure Boot support.  Around October 2012 when Windows 8 came out, Dell posted BIOS updates that added Secure Boot support, but if you enabled it and Optimus was off then you'd have a behavior similar to what you described.  The dGPU would not show anything until Windows was finished booting up.  The specific setting involved was actually the "legacy option ROMs" setting, which had to be enabled for the display to work properly pre-boot, and Secure Boot forces you to disable this.

 

I actually called Dell support on this and they didn't know anything about this issue.  They came out and replaced my motherboard, which of course did not "fix" the problem once I reapplied the settings.

 

....Dell did have updated versions of the vBIOS for all of the Kepler Quadro cards that "fixed" this, but they didn't make them available to download; they just showed up in new systems being shipped out.  We formed a collection of the vBIOS dumps at NBR so that people with systems purchased closer to launch could use nvflash to "update" their dGPU vBIOS.

 

Long story short.  I am not surprised if some older "unsupported" dGPU cards don't get along with Dell's UEFI implementation.

Those are the settings I use for my i7 4800MQ
Could go lower, probably, don't have time to test XD

I have received Anshu GaN+Sic charger today.
First impression.........
Well...... It just died after a FIRST try, I was lucky that I had an adapter with a fuse in it.

Thanks for sharing dude, how about the built in speakers? Are they better/worse than the M4800? appreciate it

Damn, wtf. Sorry to hear that happened.

It's fully dead?

I guess I need to be careful with mine... o.O

Laptop is completely fine, I was lucky that my adapter has a fuse in it, it literally shocked me, my fingers were completely black because plastic partially melted and a smell was horrible. Those were bad news. Good news — battery has arrived, works fine, 97 Whr

They're slightly tinnier than the M4800, and not as great, but still listenable.

 

Man I'd actually appreciate a raytracing GPU in the M4800. Shame there's no type-A MXM that does such a thing.

[MELOCODI]

I wanted to ask — will T1000 work with my LVDS panel?
Using Hybrid graphics, ofc.

"Should" be fine as long as you keep Optimus enabled.

I think it should work with hybrid, because then the iGPU would be driving the LCD. Output should be fine via DP and HDMI though.

Technically there are RTX 3050 Ti MXM type-A cards, but they're very expensive at the moment. Need to wait for them to hit the resell market after the next generation comes out.

 

Adlink RTX A2000 MXM type-A

Advantech RTX A2000 MXM type-A

Aetina RTX A2000 MXM type-A

 

There's also an Intel Arc A380 MXM card interestingly enough, which also has raytracing support

Link to A380?? I may want this...wonder if it'll work in M4800 hehe

Yeah it's definitely interesting also nice laptop collection 

Here is the link, it is on Jingdong which is a Taobao/Ali competitor in China

https://item.jd.com/10064806973101.html

 

I'm guessing it could be bought with a Chinese parcel forwarder like Superbuy

 

Edit: no way I actually came across a few of your YouTube videos before when browsing, cool to see you on this forum sir

Hey guys, do you have any issues with microphone on this laptop?
Sometimes it is gone from the list of devices, just randomly

Drivers updated? Also, you haven't taken off the bezel of your unit when you checked what kind of LCD you have, no? It could be something slightly loose where the camera is plugged into above the LCD. That could be a culprit.

[M4980]

seems MXM is here to stay tbh. There's just too many industries targeted with specialized embedded PCs featuring MXM modules.

 

 

This military panel PC has the Quadro A2000 MXM card:

This one must be the most overkill laptop ever made:

Did anyone try to play CP 2077 on T1000 (on this laptop)? 😆

I don't think anyone has, I would have tried for you but I don't have the game & my internet sucks currently

 

I got some best case scenario time spy/fire strike results though if it interests anyone (I had very low ambient temperatures resulting in the GPU averaging 72c and CPU 66c)
