RAM Issue with MoBo£

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Howdy. I'm building a pc for a friend, and this is what i'm encountering.
All of this is without a graphics card (for now)

specs:
MoBo AsRock z170m Extreme4
intel i7 6700k
G.Skill Trident Z f4-3200c16d-16gtz

Samsung 850EVO (with win 10 already installed from other build)

I have a total of 32gb (8gb each stick) all the same RAM

When I first put everything together the PC would boot, but not work, everything ran, all the fans came on, but no signal to HDMI. I pulled the 3 of the 4 sticks of RAM and it booted up normally. Then i powered down, and put 1 stick at a time, with a boot up in between, and that seemed to work just fine. Everything was running, ran all night, updated all the drivers, even updated the BIOS to the latest, and that was successful. Then I did some messing around with settings and over the course of 3 or 4 hours I probably rebooted the PC about 30 times. no issues. 

Went to work on another computer, came back 3 hours later, and it wouldn't boot again. so I pulled 3 of the RAM and left 1 in, booted right up.. what gives?? Do i need to change some settings in the BIOS regarding RAM? I haven't tweaked anything. nothing is overclocked, XMP is off, the only setting I changed in the bios was boot priority. 

It was my understanding that the RAM i have was a great match for this motherboard.

The CPU and RAM just came from a previously working build, and run just fine when I put it in another motherboard, so I know it's not faulty. 

is there a RAM test i can do to find out if maybe 1 stick of RAM is bad?

Thanks!

	It sounds like you may bot be getting enough voltage to the RAM on a cold boot (when the system has been off for a long period). When using 4 DIMMs you put added strain on the voltage regulators for the RAM. Sometimes you just need to bump up the RAM voltage a bit. I believe that RAM is 1.35v, you can try manually set the voltage to 1.36 and test again leaving the system powered off for an hour or more between boot attempts. You can go up to 1.4v reasonably safely with most 1.35v kits but I would bump up in 0.01v increments until stable at the lowest possible voltage.

	any sort of memory tweaking caused BSOD but with no tweaks, and voltage set to 1.4v i'm commenting this with the full 32gb of ram installed. i will be unplugging for the next hour and see if I can boot (bios settings only allow for 0.5v tweaks incrementally)

	It worked!! :D thanks a bunch! I turned it on after 3 or 4 hours and everything booted normally. left it powered off, and unplugged overnight, next morning the GPU came in the mail, I put it in and it fired right up. Who knew changing the voltage to the ram would be the solution. I have learned something new. 1000x thank you :) Currently, the build is running Win 10 pro AsRock Z170M Extreme4 Motherboard Main OS Drive - Samsung 970 EVO Plus SSD 2TB NVMe M.2 Media storage - Seagate BarraCuda 4TB HDD (32gb) x4 8gb G.Skill Trident Z f4-3200c16d-16gtz 6th Gen SkyLake Core i7-6700K DeepCool AK620 White CPU Cooler MSI Gaming GeForce RTX 3050 Ventus 2x OC 8GB GDRR6 Powered by a Thermaltake Toughpower GF1 Series 750W 80PLUS GOLD - TT Premium Edition inside a NZXT H5 Flow white case

	Glad to hear it, I hope your friend enjoys the build
