Not if he has them in separate bands. They would need to be in the same paired channel in order to utilize dual0channel mode and get the actual advertised speed. Say my board has 4 slots laid out like so.. 1 2 CPU 3 4 The channels are usually configured like so.... 1 DIMM_B1 2 DIMM_B2 CPU 3 DIMM_A1 4 DIMM_A2 The channels are A and B, and the paired slots are 1 and 2. So if he's got them in separate channels with incorrect slots, he has it like this... 1 DIMM_B1 2 DIMM_B2 - 16GB RAM CPU 3 DIMM_A1 - 16GB RAM 4 DIMM_A2 Since the channels are 1, and 2, they are unable to use double-data rate. Which basically turns 3200Mhz RAM into 1600Mhz, and tanks your performance. If you stuck them both in the A side, you have the same issue. Correct layout would be to have them in different channels, but paired slots. 1 DIMM_B1 2 DIMM_B2 - 16GB RAM CPU 3 DIMM_A1 4 DIMM_A2 - 16GB RAM The slots are usually color-coded, and if there are only four slots, it's pretty hard to screw up. 6-8 slot systems can be a bit more difficult, especially if they also have the option for quad-channel. So in the end, it's really hit or miss as to whether he has the RAM installed properly, but this is a very common mistake. Link to comment Share on other sites More sharing options...

The Chanel basics are clear to me, you usually have a chart in the manual for these, but you suggested adding 2 more units of RAM to use double channel, that's why I asked.

Each cpu has it's own memory slots and needs to have at least one memory slot populated. He would need four dimms to get that system to run in dual channel mode. With only 2 dimms, each cpu gets one, and thus operates it's memory in single channel mode. I did not mean to imply the op had not installed his memory correctly. Just that with only 2 sticks, a dual cpu system will run in single channel mode.

His message is ambiguous, I would normally interpret "(2 x 16GB matched sticks in separate channels)" as 2 pairs aka 4 dimms of 8G. He obviously knows about channels.

I have that too (currently playing a mod that makes my FPS seriously drop on horde night and when I look in specific directions). I'm not sure whether you really have a problem that can be fixed or it is just an optimization problem the developers haven't tackled yet. There are a few possible reasons: 1) Trees. Do you have planted a forest and the fps drops when you look into that general direction? There are other blocks that might do this (especially some from the creative menue), but trees are culprit no. 1. 2) Generally, are you framerate drops always in the same place looking in the same directions? If yes, is there something big and built by you in that direction? 3) I may be totally wrong here, but you have 6G GPU memory. This is usually enough, but it may just not be enough at highest quality settings. Have you disabled texture streaming with texture quality at max (the log seems to say no, but I may be reading wrong) ? That might lead to moments of heavy data shuffling between RAM and VRAM. 4) Anyway, you might play around with some of the graphics settings, especially texture quality which can easily be set down one notch without you noticing it, also occlussion, reflections and terrain quality and see if it makes a difference. There are also a few console commands that change internal graphics settings, but I'm not up-to-date which ones might help. Link to comment Share on other sites More sharing options...

No, I have planted trees but when I experienced the frames going that low they aren't even in the frame. In the log that I posted I was actually looking down at the ground collecting loot bags. 2.) I notice it most when the game changes from day to night and night to day. 3.) and 4.) I've already done that by following a few guides online. When it finally goes back to normal I'm getting 60-90fps and even sometimes as high as 100+ but when the frame rate drops it's HUGE. Link to comment Share on other sites More sharing options...
