The Latency boundary has four settings this time - and the disparity can be wide at each setting. So tweaking the thirds to get some of the perf back is advised. I assume a person that does want to adjust memory settings does care about the perf (otherwise why adjust anything in the first place? Most users want to keep their primary settings at the stated DRAM spec, so we start with the third set and work upwards. Outright stability and performance is heavily dependent on the third set due to these new platforms having a high number of page hits.
Please don't take my comments the wrong way. I'm merely trying to discuss things that both myself and users might have interest in.
Why adjust anything?
Because it doesn't work right unless you do, perhaps? There's a memory review posted to the front page of my website... and that kit works very poorly on this board without manual timing adjustment. I know what to change.. and why.. so no big deal...
But other than centvalny here and myself, very few others seem to know what to do, and the board doesn't work right.
Take a look a bit back at the posts between LunaP and myself getting his kit working... I basically followed the same sort of steps you suggest, so we are definitely in agreement on most stuff, but users should have problems like this. Your guide does cover how to deal with that exact problem a bit...bit doesn't tell users how to know that the problem they face is really a matter of CPU quality, or whatever. With taking the approach to setting timings very loosely...doesn't help at all.
Should you, in such an instance, blame the memory, or the CPU? Or the board?Edited by cadaveca - 3/3/14 at 6:54am
