M4800 Owner's Thread

Good thing it's finally working, but still i wonder why the card behaved like that.

Btw, I see that we have similar specs in our m4800, would you mind telling me how are your temps on the i7 ? Because mine is stupidly hot, at stock voltage a cinebench r15 run is enough to make it reach 95°C and thermal throttle for half a second at the end. Even tho i'm using Gelid GC Extreme (one the best thermal paste out there). My m4800 was originally the i5 version, so i was wondering if the i5 version had worse fans than the quad core m4800, thus making it overheat.

(Also maybe the i7 is at fault, it has what i think is dried up liquid metal on the die, see here : http://forum.notebookreview.com/threads/bad-thermals-did-liquid-metal-damaged-my-cpu-die.836250/)

 

I just installed nVidia Quadro M1000M in two machines: one replaced a K1100M and the other a M5100. I had thought to be clever and ordered a replacement heatsink meant for an nVidia installation but when I did the replacement, I found the K1100M machine's heatsink had the same raised copper fitment as the M5100 machine. Nonplussed, I still installed the nVidia heatsink I ordered (FC16M) only to find that temperatures were about 5C higher than the other machine. This morning I took it down again and put the M5100's heatsink on along with some rearrangement of the thermal pads and now my temperatures are the same as the other machine.

I'm trying to wrap my head around this conundrum. Okay, so the M1000M is a Maxwell generation card and perhaps has the same die height as the M5100; but wait! the K1100M is a Kepler and should have a die height difference yet its heatsink was indistinguishable from the M5100's.

 

What fans do you have?
There are AVC, Delta and Sunon fans related to which cpu and gpu is installed

I actually used gelid extreme when i bought the laptop but found it to dry out and cause unstable temps, after I switched to thermal grizzly kryonaut

 

I have the avc fans, but before the gelid i had arctic mx4 (which was worse iirc)

Well i'll be in the same case ad you, i have a quadro m2000m in the mail, but still haven't bought a nvidia heatsink. So according to you i'll be fine with the amd heatsink on the maxwell card ? i don't have any other "recent" quadro card to compare it to. I'm worried about the heatsink putting too much pression against the card, and potentially breaking it after a while.

 

I hesitate to say because my expectation from reading here was that the heatsink needed to change but I can say with certainty that the FC16M heatsink, which has clearly less copper protrusion than the so-called AMD heatsink, had noticeably more difficulty cooling the Maxwell card than the heatsink that had been cooling the Kepler card in the other machine. The spec sheet for the Kepler machine says the heatsink should be CF7NG but I didn't verify this because I wasn't expecting any strange behavior from the Kepler machine and indeed I observed none. I only had difficulty with the M5100 machine because I followed instructions and installed the FC16M heatsink, which did not cool the card as efficiently (5-8C difference under the same load with much louder fan operation).

If anyone else can clarify this situation, I would appreciate it because like Yuuji, I would rather not be overloading the heatspreader on the Maxwell card if that is occurring.

 

i received the m2000m today, and mesured the total card height (from the x-brace to the top of the die), and found out :
M2000M : 4.5mm,
M5100 : 4.15mm

I also noticed that the die placement/orientation is different (but it souldn't be an issue)


So in the end i ordered a nvidia heatsink, but right now i'm running the M2000M with the AMD heatsink not tightened to the maximum.

( i used a "pied à coulisse", i think the english word is "calipers" but i'm not sure. So it's only an eye observation, nothing extremely precise but i can indeed observe a difference between the cards)

 

Sorry for replying to a really old thread here, Aaron

I had a used Dell Latitude E6430s (inside E6330 chassis somehow), and have been using WINDOWS 10 21H1. It has a Finger Print reader embedded on palmrest and appears to be nicely connected to motherboard's USH socket with proper ribbon cable. I spent numerous days finding out which device was causing "Unknown Device (Usb Device Descriptor Request Failed)" error in Device Manager and finally found that Fingerprint reader was the culprit. Dell calls that device as ControlVault. After disconnecting it from motherboard, the problem went away.

But I still wonder why Windows 10 even fails to categorize and recognize ControlVault fingerprint reader device in Device Manager, resulting in Unknown Device on Generic Usb Hub bus.

I suspect from hardware error but after disassembling the unit, both cable and socket and the device seem just fine.

Have you had any conclusion and the reason of why ControlVault fingerprint reader cannot be enumarated in Windows 10?

Which/what "drive (ssd?)" did you move?

Best regards friend, and keep up good work (Dell Fan Management tool). Thanks

 

It can work in Windows 10. We had this error with a M4800 and it could never be "fixed" so Dell ended up replacing the unit with a 7510 as I mentioned. However, we have two other M4800 systems that did not have the error and still work fine with Windows 10 + fingerprint login to this day. It's not a software issue. We swapped drives between the systems for testing and in each case, the OS would boot and encounter the error in the "problem" unit and it would not have the problem when moved back to one of the working systems.

 

MSI's new GP66 Leopard has metal chassis! and it has M4800 style design.



"BOLD AND STRENGTHENED
The premium, bold construction on the all-new metal chassis of the Leopard makes it the most robust build to date. The hinge design has been completely overhauled with quality components and mechanisms that significantly improves its rigidity and allows for gamers to open the Leopard easily with its new one-handed opening design."

 

Only a dream if it was socketed, has MXM and a replaceable battery, and an easy to replace keyboard. Close to the M4800 but not to the extent internally.

Mine's still going strong with the WX4150, and I tested games out and not gonna lie... It runs better than my now dead G752VT.
