Memory Stabilization Help Needed

I recently upgraded my stock 16GB sticks that came in my NP9380-S. Since then I've had major stability issues that seem to have gotten worse since upgrading to Windows 10. My stock set was clocked at 1600MHz and my new set is a 2133MHz set that will only run at 1866MHz unless I manually adjust the memory multiplier to 16x from 14x. At 2133MHz I experience hard lockups and everything freezes, my computer does not restart. These happen at random, just after boot or sometimes a few hours after boot. At 1866MHz the freezes still happen but they are few and far between. I also noticed I have to run them with the command rate set at 2T rather than 1T when clocked at 2133MHz, if I try 2T my computer hard freezes a few seconds after loading my user profile each boot. I'm not familiar with overclocking but my experience tells me that my issue is most likely a voltage or timings issue. Any help would be greatly appreciated, I'll post all information I can. My memory has been tested as well.

 

I wasn't able to upload a 6th image, but here's the snapshot of my overall system specs. Sorry for the double post.

 

not sure if that laptop supports those speeds, I know it supports 1600 but not sure about the others

 

yes and no@supports those speeds. in this case, there are two things that need to play along in order to get those memory speeds: the ram sticks themselves and the integrated memory controller in the cpu!

since the sticks are advertized for 2133 mhz and u keep the timings at stock, they shouldnt be a problem. so it could very well be the cpu´s IMC, since that only supports up to 1600 mhz officially. what u can do is try and give the system agent and digital / analog IO a little more voltage and see if that improves the overall system stability. u can start off with +50 mV for each and then work urself towards the optimum in 5 mV steps. best scenario would be to find the minimum additional voltage required for system stability at 2133 mhz RAM

cheers!

PS: got the same corsair sticks, so far happy with them they can even be oced to 2200 and 2400 mhz, also not perfectly stable unfortunately

 

Awesome, thank you! I'm going to try this some point today. Since you have the same set, did your timings automatically set to their advertised timings at 2133? Mine do not. Also, when you say they aren't stable, is that at 2133 or when you go above?

 

theyre stable at 2133, even at 2200 theyre so stable that i only get like 1-2 crashes in a month when running the system on an everyday basis. just 2400 is unstable, but still applicable for benchmarks haha

in any case, in my experience it depends on the laptop and cpu, whether or not the ram sticks boot up automatically with 1866 or 2133 mhz. for example, the exact same sticks im using now i first installed in my previous P150HM, and there they would also just boot at 1866 mhz and would have to be adjusted manually. whereas now they booted up at 2133 mhz the first time i installed them into my P751ZM.

2133 timings are as follows (in the order that intel xtu shows them):

11-11-11-31-10-7-16-9-9-278-33-42-8316

good luck buddy! hope u can figure this out

 

I tried starting at +50mV but the lockups still occur at both 2133 and 1866. I am even experiencing the same issue when down clocking to 1600. I'm having a hard time figuring out if I have unstable memory, a heat issue, or both. The only reason I'm feeling like it could be a heat issue is because sometimes when my computer crashes I boot it backup and it boots into the BIOS and I'm assuming its because of the unstable overclock. But, sometimes it locks up in the BIOS if I don't leave it powered off for a minute or more.

 

do u have any overclocks applied in ur system when this happens? if so, its best to revert to full stock and check ur memory again to make sure to be able to pinpoint the cause of these crashes. it could also help to go above +50mV and to maybe check the stick individually and also trying them in different slots of your machine. i know, i know, this is nerfing work, but troubleshooting is never really fun... :/

 

I haven't overclocked anything until I got this new memory, and the only thing I've tried doing is getting the memory to run at 2133. I've tried putting the memory in slots in 1 and 3, but my system will only post while they're in 0 and 2. What would you say a safe maximum voltage would be for the 4800MQ? I noticed that when my computer locks at when the voltage is set to 50mV that IET reverts them back to the defaults. But if I'm just adjusting my memory from 1600-2133, it crashes and boots back up with the same settings. I posted a few months about this lock up issue with a different set of ram and someone pointed to it possibly being a bad AC Adapter, but I haven't seen any obvious indicators to that.

 

phsew, complicated matter...

ok, so it seems like your system doesnt like the overvolts on the system agent and the IO areas... another option would be to check the ram sticks themselves for any potential errors using memtest for example. if they turn out to be fine at 1600 mhz then that would be another pointer towards a weak integrated memory controller in your particular cpu, that would just not support anything beyong 1600 mhz...

 

After the last time I posted I went into my BIOS and started changing a lot of settings from auto to what they should be. Such as, PCIe set from auto to Gen3, disabled msata ports that were not in use, set sata HDD type to SSD from auto, disabled intel VT, disabled hibernation, and there were quite of a few other settings I modified. I did not change any voltage or clock settings. Since then I haven't had a single crash running at 1866 using auto timings, strangely they are also automatically running in 1T mode.I really don't know what settings may have increased stability that I changed, I was just bored. I'm about to test 2133 for a while and see what happens.

 

ha, well look at that!

i got a similar case but with my 3940xm AFTER upgrade to windows 10. it will BSOD from in couple of minutes to few hours whenever i oc OR UC in xtu, just anything other then default. including just adjusting max voltgae with clock speed untouched (stock). everything is perfect in windows 8.1. it should be windows 10 compatability issues
