Blue screen ram question

[nicknmulli]

Hello,

After recently dealing with some blue screens and freezing last week I removed one of 8gb ram sticks as a Hail Mary and that seemed too stabilize everything and I was not getting anymore blue screens for two weeks after that. I thought the stick was defective or broken so I bought another one of the same brand, speed, etc. and installed it, I received a blue screen for 'Kmode exception not handled" almost immediately after installing it. I have since removed that ram stick and am now back with my single 8gb but the system is stable. Any help is very much appreciated.

Thank you.

Memory is guaranteed in the form sold. Doubling up with identical memory has no guarantee to work with the old memory.

Try lowering the Mhz a little in the BIOS and see if the crashes subside. Also try the RAM in different slots. It should work.
Also see if you can run the windows memory test to see if the RAM is just not simply faulty.

Lowering Mhz is separate from lowering the voltage correct? Also does it matter at all which slots I use? I'm not sure I understand calvins post, how am I supposed to get back to 16gb if I have no idea the memory will work?

Not really, you reduce the RAM frequency. E.g. normally the BIOS has preset speed e.g. 2600 can be lowered to 2400 etc. I would not mess with voltage. There might also be a memory tune button on some motherboards that test the RAM for you (depending on board of course). You can put the RAM into the similarly coloured slots. This way you will run DUAL channel instead of single channel. If you put one into blue and one into white slot then you will get single channel 16gb which is slower overall.

Thanks I will try those suggestions first, do both sticks need to be installed before I mess with the frequency?

Changing the frequency didn't seem to help, I tried the second set of slots and then reverted back to the initial slots I was using with both 8gb sticks, both combinations resulted in freezing within 15 seconds of booting with no blue screen. I triple checked to make sure everything was seated securely. I am back to my since 8gb stick now and its stable.

Edit: I wanted to add ii was experimenting with the different slots and it appears there is only one slot that I can use and have the computer actually be stable for than 5 minutes, using any of the other 3 results in freezing.

If you move the Second stick of RAM into a blue slot then you must also move the first stick to the matchin blue slot. The sticks should be in the same colour slots. So you should have 2 options either all blue or all white slots. And you can try rotating the sticks around, first slot this second slot that. So you actually should have 4 options. BUT try to stabilise your PC and run a memory test. You can also switch XMP on (if your RAM supports it) if it is on or switch it on if it is off. XMP can cause issues but for me it works great as my RAM is overclocked by default. You have not given us info about your RAM or motherboard, but first run a memory test from windows.

My personal pc is working with 4 different sticks, no problem whatsoever. At first it was doing blue screens as well, but i manually set ram timings. Apperantly when overclocking timings might change as well, which causes the blue screens. So after i manaully set them up i no longer hat blue screens caused by ram. Hope it helps for you.

Hello,

I am using Z170A GAMING M5 and Corsair Vengeance LPX 16GB (2x8GB) DDR4

After some hours of testing I can confirm as of now that DIMM slots 3&4 are working and stable with 8gb sticks in each. It appears DIMM slots 1&2 will result in a crash if memory is installed into them, I am going to do some further testing and see. I can the memory test with both sticks installed and it reported no errors with the memory.

EDIT: I wanted to add I also updated my BIOs to the latest version and this did not stop the freezing.
