SuperMG

These cards work in the M6800, just need the RTX heatsink (150W, 4 heatpipes) for them and eDP display (screen and motherboard) for better performance + backlight mod cable.

Hey, will you test any RTX 4080 or 4090 MXM? They are far better than the best HD 8970M. I got 16000 GPU scores in TimeSpy and 305fps average in FurMark 1080p bench

The vbios version is the same as XVSION!!! You sure it's a ZRT design you got? By comparing the back side of the PCB you sent me. I compared it with ZRT and X-VSION models. Sadly, they got you... You got the X-VSION one which isn't the one that was advertised in the TAOBAO listing

https://www.x-vsion.com/product/16-gl1654p-gaming-laptop/ Hello, X-VSION are selling laptops now. They all state "replaceable GPUs" but it's not sure if those are MXM GPUs. If they are then wow. I asked the VBIOS files from them because they're maybe 100% using the same chips from their MXM cards. The laptops have eDP because of their internal display, so there's a chance that they have the correct VBIOSes that don't set the "edp to disable". Maybe the backlight pins are back only on laptops? Or maybe they're controlling the whole backlight/brightness from the motherboard instead...

No you are lucky for having a potential ZRT RTX 4090 VBIOS. For M6800 I think 135W TDP should be the max for dGPU. 150W works but needs beefy PSU.

I tested the 4940MX in the Alienware 17 R1 and... Shocking results... Max 71W in ThrottleStop bench instead of 58W. CPU-Z: from 380 to 430 single score Multi-thread: 1880 to 2200... Can hit 4GHz on all cores. I put the i7 4700MQ in the M6800, I get 2.3GHz on all cores, what?? Max 24W... I set the cores to the lowest possible, I get 2.4GHz at 26W..... (Non OEM Battery) I didn't reset the CMOS and the NVRAM values yet. Maybe I should? I remember I was able to get 3.1GHz on all cores (OEM battery) Edit: fixed the 4700MQ turbo with CMOS reset and got 3.4GHz on all cores at 58W max. Multi-thread is 1800 points

The 4940mx crashes at -110mV core so... Not a good chip maybe. I'll test on 17 R1

But I don't wanna get power limited when both GPU and CPU work. It's better to get the lower TDP CPUs. I'll test the 4940MX in an Alienware and see if it does the same issue. The 4940MX is requesting too much amps, maybe higher than the non extreme CPUs.

I see people with Dell laptops reaching 4GHz all cores with the 4900MQ

Yes and I can't increase that. So it's better having a 4900MQ that's 47W than the 4940mx that's 57W...

But the 900 series have a lower designed TDP and at 58W I'll get more performance than what the 4940MX did at 58W in throttleStop bench... The 4900MQ can do 4.2GHz on all cores, so 4GHz on all cores could be more stable and possible than the 4940MX in the M6800? Edit: I undervolted to -80mV and I was able to get 3.7GHz on all cores, instead of 3.6GHz with -40mV. Interesting... Still low, if I had a 4900MQ, maybe I can get 4GHz easily

It needs external power, so no.

M5000M and 980M

But... The palmrest doesn't fit and close too... Still the same issue as before because of the VOLUME CONTROL LED board...

Hello here are the results with the new 4 HEATPIPES GPU heatsink. Heaven Benchmark 4.0 (1080p Ultra): 258FPS average Temperature max GPU: 77.5C Temperature max hot spot: 86.5C Max core frequency: 2385MHz Max TDP: 149W FurMark 1 minute 1.37 (1080p): 306FPS average Temperature max GPU: 81.6C Temperature max hot spot: 92.8C Max core frequency: 2370MHz Max TDP: 153W TimeSpy (1080p): GPU Score: 16090 Temperature max GPU: 81C Temperature max hot spot: 92C Max core frequency: 2370MHz Max TDP: 152W No thermal throttles. The only limit is the Power Supply if we run the laptop without battery. The power LED blinks orange and white. To fix that, I need to use a 330W PSU and use a Core i7 4910MQ, since the 4940MX it's useless, uses 10W more and can't overclock well on the M6800. And optionally: use a 135W VBIOS if we can find one... Maybe @DynamiteZergcan get one from ZRT. With the 4910MQ you have turbo bins and can use 3.9GHz all cores with grub, right @JadeRover?
