TL;DR: dude asked for my RAM model number, I said F4-2400C15D-16GVR. He said 2400 should be enough info he needs. He said to up the DRAM voltage by .05. Doing this along with turning on "virtual super resolution" made it work! How did he get .05 from me telling him my model number and why does virtual super resolution seem to have to be on as well?

I was recently having some terrible PC problems. The screen would go black EVERY TIME i went to play a game. after over a month of trying to figure it out I started to wonder if it was my RAM. Someone on here asked what the model number was. I wasn't sure exactly where to find that, but I assumed it was F4-2400C15D-16GVR, because it was on the back of the package. He replied saying that 2400 should be enough information he needs, so to try upping the DRAM voltage by 0.05. I did this and I didn't work. Days later, I tried turning on "virtual super resolution" on my GPU settings and it worked! A couple days later though, When I turned on the computer, it said there was an error and prompted me to reset BIOS settings and to restart, so I did. Then it wasn't working anymore. I realized that even though virtual super resolution was on, the DRAM was no longer +.05 so I went into the BIOS and added the .05 and it worked! I'd ask him, but its been days and he hasn't replied.

I want to know why that worked and why virtual super resolution has to be on as well.

DRAM can have numerous reactions depending on what you do with your rig and what components your rig is based on. +0.05 is a common starting point to check and see what is going on. It may have been me, though many others have picked up on this and offer it as a suggestion - if it was me and I missed a reply from you, my apologies, the last few weeks have been rather hectic for me. If so again Sorry :(

I believe I know who gave you that advice. He is one of the most competent experts on these forums, and is especially knowledgeable about RAM. He is also active on the GSkill forums and might be affiliated with them, not sure, haven't asked him. Upping RAM voltage can help with memory stability. As far as the VSR helping in games, I'm sure he's seen that issue also and knew to give it a try. Why it helps, I can't tell you. It may be that VSR helps with scaling issues but also places more stress on your system RAM, requiring both to be done to get effective results.

yes it was you! don't worry about not replying, I can't thank you enough. I was so lost on what to do about my problems, and I was so frustrated thinking that I wasted all that money on getting a good PC.

If you have the time and if you are able to, do you think you could explain a bit more? like, why 2400 was the important part of the number? what if it was something different? Or did that have nothing to do with it and +.05 is just a general thing to do? I am interested in a career with computers, but I'm still getting into the basics.

Thank you again too. I've been enjoying Rust, Overwatch and some other games since this was fixed!

Would have to see the thread, but depending on the rig, would guess it was an instance of where thought the MC (memory controller) may have been straining a bit at 2400. With DDR4 can often simply smooth things out with slight voltage increase to the DRAM...if that would fail then would look at the MC voltage. Could also have been that the BIOS hadn't been updated yet to properly set the sticks up for you Ripjaws V sticks

can I ask one more thing then? the same problems I used to have still OCCASIONALLY happen on really intensive games. The game runs fine, but the screen still goes black or freezes. would upping the voltage MORE help?
