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

Well that's just a number given by intel for the design TDP of these CPUs so that manufacturers can make heatsinks accordingly. What is important is the voltage per clock ratio that each chip can do. On my zbook 17 g2 with i7-4810mq, when pushing all core to 4.0Ghz it hits 70w. It would be wiser to stay with the 4940xm that has much better silicon meaning you can undervolt more before you crash meaning higher clocks for the same power. All haswell mobile quadcores have the same physical die (some with more cache than others), the way intel names CPUs is that those that can be fed less voltage (=less power) for the same clocks achieved are marketed as the XM chips. For example, this same 4810mq will crash at -20mV at all core 4Ghz. The 4940xm has way better overclocking headroom than the 4900mq. I'm ready to bet that the 4940xm reaches higher clocks than the 4900mq in your power limited system because you can get 3.7 Ghz all core @ -80mv witht eh 4940xm whereas the 4900mq will probably crash at -45mv = stuck at 3.5Ghz all core.

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

Yes, that is because you are being power/current limited. By undervolting, the CPU can reach higher clocks for the same power/current, you need to investigate all power limiting factors, but in your case it sounds more like current limit as throttlestop shows "EDP other" limit reason

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

That's a easy fix, solder big wires from the main power rail (19.5v after 2nd Mosfet) to the power pins of the GPU, GPU is fed main power rail through the MXM slot anyway. Even up to 4.3Ghz all core see the comments at the bottom of this page : Intel Core i7-4910MQ Mobile processor - CW8064701474105 / BX80647I74910MQ This is because this is a "900" series CPU, just like 6920HQ and 7920HQ, these have +6 turbo bins VS the +4 on other i7 mobile CPUs But it sounds like you were hitting a hard power limit/current limit so bumping the turbo bins won't do you much good. Power limit editing on my m6700 worked great, can't help you more from what we said in PM with the m6800 as I don't have the machine (nor the m4800 that should have a similar implementation of power/current limit in the bios)

It needs external power, so no.

Yes I used the stock UHD display cable : 06GXDN it is the only way to get 4 lanes of eDP displays working = displays with > 1080p and or > 60Hz (without making your own display cable) The display I have is this one : NV173QHM-ny4 BOE NE173QHM-NY4 Overview - Panelook.com I got it as it was a good deal on my local second hand shopping website (40 euros for the display) Display connector side doesn't matter as the UHD cable is made for displays that have a connector on the left side (looking from back of display) and the cable leaves from the left hinge (looking front of the laptop) = You can use "left" or "right" sided display. The display I used has a connector on the right side (looking from back of display) so I had to make the LCD cable loop back on itself inside the laptop lid so as to connect to the display. There is enough room in the "chin" below the display in the back panel to get the cable to loop back without making the LCD bezel bulge. I taped the display bezel back in place and no problems whatsoever since. The only limit is bandwidth as we are limited to a DP 1.3 connection, even in dGPU mode, see here (DP1.3 columm on the right) : My display works as it is 1440p 165Hz 8bit. If you try to use 10 bit 1440p 165hz display you will have to run it at a lower refresh rate to use 10 bits or run in 8 bit mode to get 165Hz. During testing I got 4K 10 bit to work at 60Hz, trying 8 bit 120Hz gave artifacting and flickering image. Hope this helps ! If you have more questions I can try to answer them as well. Regards,

Yes, those are the ones. I don't know if you could fit a full fat 980 in (without the "M"), IIRC is it a weird shape and requires an extra power connector. Everything newer than that is eDP only. [Edit] This is the GeForce 980 (no "M").

Idk if anyone has said anything but: I have a Quadro P5000 working with the 17 R1 (Ranger) running an i7-4940MX. Just had to switch to IGFX on a 60Hz display to make the power draw consistent at 95-100w, and modify my drivers using NVInstall (Check device manager and see if your card is trying to call for a different device ID, it'll guide you to the right P5000 to select when adding hardware support, they're definitely different in terms of what's installed) and boom, it worked no issues. Also worth using one of the OC bios's you can find on TechPowerUp's database, or use a hardware flasher to flash the iMac OC bios from the mac forums. Also on LVDS

M5000M and 980M

@SuperMG @Annihilator @Aaron44126 What's the fastest mxm card we can deploy in a M6800 LVDS setup without the mux limiting the performance of the mxm card? P5200? RTX5000? Or?

That sucks... But we don't really need the volume control we do need the LED board to see the status.

Lossless Scaling allows using a second GPU for Frame Generation. I tested it initially with the 3090Ti (raster) and 1080Ti as the frame gen card. I was able to get stable FPS with Monster Hunter Wilds running native at 3440x1440 and from a perception standpoint it was smooth. This was running 3090Ti PCIe 3 x16 and 1080Ti PCIe 3 x4 which is pretty limiting for this type of scenario. I would like this for smoothing out 4K120 until all the new stuff comes out. Ideally you run (for 4K120) at minimum PCIe 4 x8/x8. You also want to set a framerate that doesnt cause the GPU to sit at full tilt, so if 110 is your max average then set the framerate for 90, let the mule carry it to 120 via dynamic framerate target. It also has the standard 1/2/3 multipliers also.

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

It looks like we have a winner here! I need to wait for the eBay seller to make the same heatsink setup for me!

My friend, BIOS version 1.9.3 is newer than 1.3.2, and you won’t have any issues. This problem will be resolved by upgrading the BIOS to version 1.9.3. https://www.dell.com/support/home/en-uk/drivers/driversdetails?driverid=tc3x1

I believe the very latest BIOS can only be downgraded to 1.12.0. The later (more recent) BIOS burn e-fuses in the CPU as I was unable to boot after recovery flash below 1.12.0 without replacing the CPU to boot 1.3.2

Wow that is amazing. I need to do this!

In the past I tried to adjust the CL values but they would get overwritten by the SPD read of the DIMMs upon boot. (guessing that is why they changed from my RU.efi settings) The DIMMs I purchased are only 2666mhz max per the label. I think these are TimeSpy scores: ~21k

Yeah, UMAF did work with both the A51 18 and Dell Pro Max 18 Plus. Sometimes it would freeze or fail to apply settings though so you have keep trying if something did not stick. Just be aware that with any later bios update Dell may write-protect the EFI setup variable region which effectively disables modifying any hidden settings. With the Legion 9i SREP worked on the shipping bios but none of the updates. NGU and D2D can be adjusted but on this one memory timing changes always fail to train. Its basically stuck at 5200MT CL38 Dual Rank (the 64GB Kingston Fury kit). M-die also worked at 5600MT but timings were much worse than the Kingston kit. There will be an 18 inch Uniwill chassis but this year it only gets up to 5070 mobile. Next year its supposed to have better GPU options according to Prema, so Eluktronics should end up carrying it.

Offloading frame gen to a secondary card via which method? In regards to just generically picking amongst that group, it would be the 9070xt but depending on how you're offloading and executing FG, it would come down to potentially best bang for the buck too. Did you ever give Smokeless a try on your Alienware 18 or Dell Max 18 before sending them back? How much flexibility do you have on your Lenovo? I really wish they had an 18" version of the Hydro. 😞 I'm content with my Alienware 18 275hx/5070ti primarily because it was free so bang for buck is undetermined since buck == 0; 🤣 I haven't had much time to play around with it lately though. I've been plowing through Midnight at 4k Ultra settings and I think I can safely say we've reached end game with the 5090. Numerous spots can get into the mid to high 80s utilization but nothing so far can cap it out. This shows a 5080 or 4090 would still hit walls in some spots due to the high utilization spots on the 5090 As I'm sure you've experienced, Silvermoon, like Dorongal is an instant player physics frame killer.... ------------------------------------------------------------------------ AMD officially dropping the 9950X3D2 April 22nd...... I don't think this is going to do much of anything for gaming overall with the same fabric limitations which will be greatly enhanced in Zen 6 but you never know..... I'll be keeping an eye out on this one as I skipped the 9850X3D as it seemed a silly bin bump that can't even sustained its rated speeds in many scenarios vs the 9800X3D which is rock solid. ------------------------------------------------------------------------------- Official confirmation of the 290k being scrapped (which we knew already) 270k officially available but showing up for $349.99 not $299.99 shipped and sold by Newegg and Amazon. Microcenter also has it listed for $357..... Shenanigans! Of course it is popping up in combo deals already as Newegg (and soon Micro$enter) tries to bundle and move stagnant hardware.... I'm going to hold off and let the air clear a bit as this SP83 265k is doing well enough atm.... --- Cheapest GPU prices: 5060 8GB........$349.99 5060 16GB......$699.99 (?) 5060ti 8GB.....$379.99 5060ti 16GB....$539.99 5070...............$629.99 5070ti.............$913.99 5080...............$1289.99 5090...............$3799.99 (You have TWO kidneys....you'll be ok!) 9060xt 8GB...$329.99 9060xt 16GB.$439.99 9070..............$599.99 9070xt...........$699.99

I have same problem with P775dm3

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?

One of the best things about owning a 9070 XT is, unless you do something stupid in terms of choosing the wrong GPU, you do not have to give a second thought to the garbage 12VHPWR connector. Having the legacy 8-pin PCIe connector is, in my mind, the most compelling reason to own one. Thankfully, hardly any of them use 12VHPWR connectors. The few that do deserve to be ostracized for their exceptionally poor judgment and lack of regard for people that purchase their products.
