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?

I know that MX-4 isn't the best but what I'm saying is that the stock heatsink handles a 115W 4070 with a regular paste. I could use PTM7950, it'll maybe save me 10C! Full copper doesn't mean everything too. The M6700 custom heatsink had same performance as the OEM heatsink with a M5000M! It usually depends on the heatpipes themselves and on the air conductivity. The custom one was using the same heatpipes as the OEM one.

I don't think this would handle the 150W VBIOSes. It can handle 125W GPUs for sure. For MXM-A RTX 4060, 4070 you need to cut the heatsink for it... Very nice designs from X-vsion... The stock modified one can handle 115W 4070 very easily and the temps are staying cool. I used MX-4 paste and not ptm7950. For example the custom RTX Heatsink I got for the M6700 throttles instantly in FurMark with a 150W Ada card. But this heatsink can handle 100W easily.

I have 970M 6GB from Clevo and M5000M 8GB from Dell. M5000M: https://www.techpowerup.com/vgabios/188273/188273 For Alienware... Why does the M15X work with Maxwell cards? In dGPU? I tried today with Maxwell VBIOSes (970M and M5000M) that have no UEFI/GOP: Boot with LVDS cable: nope Boot without LVDS cable: nope Boot without LVDS cable and DVI plugged in: nope Boot without LVDS cable and HDMI plugged in: nope Even tried to do the same with a Quadro P3000 UEFI, nope. The 485M works without LVDS and displays in DVI/HDMI... It's just a blackscreen, no backlight, no post, no OS. Nothing. Just fans stay on idle.

I get 56W max in throttleStop benchmark so I don't know , no bsod

No, running into 45W TDP limit in CPU-Z. 61W is good for me. Using 240W PSU. Getting "EDP CURRENT" error in throttleStop.
