Increasing RAM to another 8GB won't necessarily eliminate lag if you're targeting a 128-bit architecture.
Increasing RAM to another 8GB won't necessarily eliminate lag if you're targeting a 128-bit architecture.
Hey, a year ago you set up your PC with those specs and faced some lag issues. You mentioned using dual-channel for better performance, but due to budget constraints you ended up with single-channel. Now you're curious about upgrading to dual-channel with similar RAM configurations. Your current setup includes 8GB of RAM split between two Corsair Vengeance cards. If you switch to a single 16GB Corsair Vengeance @2666 and keep the other card at 8GB, it should still work, but performance might improve slightly due to better bandwidth. Regarding the channel width, dual-channel will indeed use 128-bit channels instead of the 64-bit in single-channel setups, which can help boost speeds.
Discussed on PC Gaming – What kind of lag is this? Lag originally refers to network issues, indicating a problem with your connection to the game server. Simply adding more RAM won’t resolve it if the core issue is elsewhere. If you’re using a general term for lag, please specify the type and where you notice it. I suspect you might be experiencing frame drops or input lag. Likely, warping is the culprit. To identify the source, it would help to see your system usage during the laggy moments and check the temperatures involved.
FPS drops even though MSI Afterburner works fine and the system stays cool. The problem lies with the graphics settings. First, check if you're using a single-channel configuration with 16GB RAM—it might restrict performance. Second, consider adding an 8GB Corsair Vengeance module to bring your total RAM up to 24GB. This would split the memory into two parts: one at 16GB and another at 8GB, utilizing the full 128-bit bandwidth.
A lot of interruptions here. They’re recommending dual-channel now that new games drop, but I only have a single channel. This has been an issue for a while since the releases started. Should I upgrade to another 16GB or 8GB?
1) Varies by game, but probably not an issue with your Intel CPU. 2) No. For dual-channel performance, all RAM must match. That’s the usual rule I remember from back when I was learning about that part of tech. How much will frame rate decrease? It seems to depend on in-game events like explosions or loading new areas.

I attempted Watchdogs 2 and experienced significant lag, similar to Horizon Zero Dawn and most Ubisoft titles—even at low settings. Recently, Ubisoft released specifications for their upcoming games requiring dual-channel 16GB RAM. I’m curious whether using dual-channel would improve performance. I currently have a single-channel 16GB system, so I’m unsure if upgrading to dual-channel would help. What’s the practical benefit? Should I purchase another 16GB or keep the existing setup? The video you mentioned likely demonstrates this comparison.
From the video, a 20% boost appears possible. But since both videos maintain consistent frames per second, the problem likely isn't tied to RAM. Dual channel might help if your current setup is unstable, but it could improve results only if you already have steady FPS.
Because the resolution isn't important, I'd attempt using a freshly installed GPU driver. There might be other factors to examine, but I'll ask someone more familiar with current hardware and games for further details. The last time I handled something similar was with BF4.
