Pretty much the way to do it. As long as cpu's imc can scale up then most mem. profiles should work on any capable ram sticks with only vdimm adjustment needed. If the ram can't go for specific profiles then adjustment is necessary on primary timings and latency boundaries settings. No need to tweak secondary and tertiary timings.

Unless it's 8 GB sticks, which have no profiles. biggrin.gif

I mean, if we go by Raja's guide directly, it would not be doing as you say.. it'd be hitting the tertiary first. Which makes my comments exist in the first place.

Since we are close to the end of DDR3...if this stuff isn't dealt with...well, it never will be. Hopefully DDR4 will have more users interest? tongue.gif

And therein lies the rub. One needs to know if the IMC can do it and also has to bear in mind that most users that we need to guide want their DRAM to work at stated primary specs and rated VDIMM.

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 so I prefer to dial out insatbility there before I resort to asking people to ramp voltages beyond board auto rules.

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.


So, anyway...


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?

Of course, and rather than choose a lower operating point the user wants the DRAM to work as advertised or faster. That's why they make adjustments in the DRAM section.


And that's why I wrote the guides the way I did smile.gif There is method there to get the kits that won't work on auto working. I do it in a way where people don't worry about degradation due to VCCSA or VTT being ramped higher than some would like (that's a big fear I have to combat in some users).


Nothing personal at all smile.gif

Yeah, I understand that. But we clearly have many users that are interested in more...how do we give them that? How do we take a "normal" user into an LN2 user?

I'd very much like to see the foundation for that to be developed with OEM support. I'm not talking OC league..or anything competitive. HWBot just doesn't meet my needs.

If they are still stuck then we walk them through it.

Most of the guys I meet just want their rigs to work as they think they should (the Ln2 types or even those that will get into it are a very small percentage). I spend more time helping the types that just want a working system (even with a killer rig) than those that are looking at getting into tweaking as a hobby or have ambitions for Ln2.

Hey guise! Finally got my scheit together, and alas, my first post!




Can't wait to start tweaking this thing.. Saw so many options in the bios!!

Hello all..

i just godt my new system up and running..

4930k
R4BE
32gb TridentX 2400MHz
2x EVGA gtx 680 classified SLI
everything is watercooled.

i just ran Valley Benchmark.

1920x1080
High
1 display
Antialising OFF

On my MSI bigbang Xpower was the score 6100 (AVG FPS 146) Both GPUS runs at 98 - 99%

Now on R4BE same settings 4200, (AVG FPS 106) and now the GPUS just runs at 50-70%


And BF4 for example runs like S- - - !!?
