M4800 Owner's Thread

Thanks a lot for all the links. The way I make sense of it:
The M4800 will not actually run memory at the speed of 1866 MHz; it is currently Haswell-limited to running it at 1600 MHz. It will only time such memory faster (usually CL9 instead of CL11).

There are some pretty confusing statements, then, in the specsheet and the manual.
And there’s the weird statement of the maximum of 16 GB RAM for the faster RAM, while you proved through your “optimisations” that one can have 32 GB of CL9 memory.

 

My M4800 came in today, didn't get the chance to turn it on and test stuff, but the palm rest has a bit of rubbery feel, when did they add that? I had a M4600 and it didn't have that rubbery feel, did they add it with M4700 or this model? I like it, it's nice.

edit: played around with the system, hardware wise everything seems fine, except for the keyboard, D key sometimes double taps, it's annoying, it's just the D button that does it, every other key doesn't do it, anyone run into this?

edit 2: for anyone who's curious about how well K1100M overclocks, I installed MSI Afterburner and got it to +135 MHz core and +200 MHz memory and it's stable, I can't go any higher on core clock since it's limited to +135 unless I use a modded vBios.

Played some WoW, Diablo 3, ran Heaven benchmark, and during all this time the GPU peaked at 61c.

 

M4800 and M6800 run DDR3L-1866 at 1866MHz just fine. It's not officially supported, but it works well. You can also run 32GB at that speed, but then it's not supported by Intel or Dell. A co-worker's wife just got an M6800, and I put 16GB of 1866 in, and it ran full speed, no issues. Putting in the 16GB of 1866 plus the factory 8GB of 1600 got 24GB @ only 1333, though. She's since gotten a second kit, matching the first, and is now 32GB at 1866, still passes memtest without issues.

Since I need stable and already had some 1600, I put 32GB of 1600 in mine.

As for CAS latency, it's not a big performance change once you're dealing with high speed DDR3. Just keep it matched and the timings don't matter much.

 

are you able to force the nvidia card so it is always in use? i've an alienware 14 and it has an option (fn+f5 then a re-boot) to just use the nvidia card or use the gpu switching. i prefer to use just the nvidia card alone. i've just got a m4800 but can't see a way to force the nvidia card only.

 

You can disable Optimus in BIOS so it only uses Nvidia GPU.

I don't think there's a way to do it in software, but you can make it so that Nvidia GPU is the default graphics processor when you open apps, maybe not what you had in mind but it's close.

 

great thanks Idarzoid i'll give that a go. i'm trying to find out more info about the panel i got. i went with the 'UltraSharp FHD (1920x1080) Wide View Anti-Glare'. looking at

device manager > monitor > properties > hardware ids shows MONITOR/AUO21ED

any idea if this is an ips panel or not? google didn't come back with much info to help me.

 

I did not find how to make a search on this particular thread so I have a question for you. Have someone calibrate the m4800 FHD screen? If yes can you share an ICC profil.
Thanks!

 

It's not IPS, mine's '15.6 Inch UltraSharp FHD(1920x1080) Wide View Anti-Glare LED-backlit Premium Panel Guarantee'

Do they offer 1920x1080 IPS on M4800? I thought it was just FHD and QHD+ (which I think is IPS)

 

To disable Optimus and force Nvidia use all the time, boot, enter BIOS via F2, under Video, disable switchable graphics.

This applies to the M4800, E6530, and E6540, same option.

Idarzoid: K1100M overclocking: Since I was planning on switching out for a K2100M in the near future, I've been beating mine much more aggressively. I'm currently using an 840MHz base clock and a 900MHz max turbo clock, and memory at 900/1800MHz. It clocks like mad, probably because the Quadros are the top bin of the top bin of the GK107GL hardware.

 

How did you get turbo working on K1100M?

It's overclocked to 840Mhz, but that's all I'm getting, I checked Nvidia inspector, it tells me that even my turbo clock is still 840MHz.
