running:
i7 8700 @ 3.20ghz
Gigabyte Z370 HD3-OP rev. 1
Had 2 sticks of Corsair Vengeance LPX 4GB DDR4 @ 3200MHz running in slots 2 and 4 (provided you view it as 1,2,3,4) on XMP profile 1 for months with no problems.
Just bought another 2 sticks, same RAM, same speed and inserted them into slots 1 and 3. Everything was fine but about an hour into using the computer I would get a blue screen, with the stopcode MEMORY_MANAGEMENT and then later with another one that I only wrote down as FLTMGR.SYS. Googled around, ran MemTest 64, ran windows memory diagnostic and all came up blank. Some other things I tried were making sure the harddrive had 15% free space on it and reseating the modules. Updating the BIOs was another common solution. I Realised I was on version F1 so upgraded to F11b. I didnt realise this had set XMP back to disabled and my RAM was running at 2133MHz for about 2 hours before crashing again.
Some more research and I noticed that although, in the BIOs, Profile DDR Voltage was set as 1.35V (the same as on the RAM stick), the DRAM voltage in a separate menus showed Auto, followed by 1.200V. I manually set this to 1.35 and again, the blue screen. Also checked each channels sub timings and compared them to the stick, both set to 16 18 18 36.
The fact the computer runs flawlessly, or appears to, for hours at a time then shuts down.. It feels like the solution is so small and just out of reach ;/
also: from what I've read having 4 sticks instead of 2 (even if total amount of ram is the same) increases the load on the memory controller, so I need to increase voltages to that regardless of whether or not my CPU is overclocked? VCCIO/VCCSA or something? Perhaps this is the next thing to try
other possibly relevant info/thoughts: Memory Multiplier Tweaker is set to 1. I've read 2 could be beneficial?-something about memory training.
both interleaving options are auto. could manually enable them?
I believe Command rate is set to 2. I should manually set it to 1?
I also noticed onboard graphics is "Enabled" when I use my own GPU. Supposedly this will generate heat and power for no reason?
DRAM Training voltage is set at 1.20. set this to 1.35 also?
**A lot of these potential fixes might only be necessary if the computer wouldnt POST at all so I don't want to go through things at the risk of making more of a balls up that are obviously not the case (but my knowledge is much to small to know which should be tried and which shouldnt) because you would know much sooner than hours after running the pc.
