It makes sense. I think the frequency matters a lot for the 8g stick, the MemTest showed error within 5 mins even though I used slow timing 14-14-14-36 for clock at 2400mhz. Some websites showed the 4930mx or 4940mx can support DDR3(1.5v), I tried to set UEFI variables to manually select "DDR3" instead of "DDR3L" to run 2400mhz, but it didn't show effect. I saw someone online can run 2133 at CL10 in AW 18, have you tried that in your machine? I can't get CL10 work fine for mine.

I can run 2400mhz (12-13-13-36) with 4x8G Corsair DDR3L in my Dell M6800(4940mx), it passed MemTest86, 3DMark, PCMark, but couldn't pass Windows based MemTest. At the end I have to down clock at 2133 (11-11-11-30) to pass the MemTest. Not sure is it because my ram cannot handle 2400 in 1.35v or my mother board cannot handle 2400mhz. I also used Thaiphoon Burner to flash the spd, no setting in BIOS.

It took me 1.22v to stabilize 4.2Ghz and 1.28v to stabilize 4.3Ghz of 4940mx in my Dell M6800. I think your voltage is not bad. Even though I used liquid ultra, I still suffer from thermal throttling when clock is over 4.1Ghz under XTU stress test.

Hi Khenglish, do you know how to unlock the tdp(go beyond 47W and 58.75W) in M6800? I have a 4800MQ, and I unlocked all the values that I known(related to power, tdp, current, etc) in NVRAM, and set Turbo Boost Power Max(160W) in XTU, but it doesn't work, even though I set it in NVRAM(Cpu Power Limit1, Cpu Power Limit2, Cpu Power Limit3 as 160W). The highest TDP I can get it is still 58.75W, then after about half a minute, the tdp will drop back to 47W. My current setting is voltage offset -93mv(38,37,36,36), 4 cores at 3.6GHZ for half a minutes. I am thinking how to have 4 cores at 3.8 or 3.9 GHZ.
