Bump up your Vtt (QPI) 1.30v is probably too low for DDR3-2000 MHz. Try something like 1.3625v (probably about 1.32v real) and see if that helps.

Well, I tried higher Vtt but no joy. Why is it that I can run prime95 no problem, but linx is a no go?
Do I have wrong settings maybe, or does linx put more stress?

try running with HT off maybe and try manually setting qpi data link manually at closest to 6400 and then try toying with your rTL's manually as they tend to be choosen too tight or too loose when set to auto.

skuldarin, any suggestions on what to try with my rTL's?

Thanks to you two guys I finally passed linx. I think the biggest factor was the HT. That leads me to three questions.

1. I was able to pass prime95 with HT on at 4.6 but not linx. Once I turn HT off I can pass linx. How important is it to pass say 20 loops with linx if I can pass prime95. I mean other than benching and being able to post in the 4.5 club and stuff like that because linx is the requirement? Is it good enough, or in other words, is my system stable enough passing prime95.

2. Is a higher speed with HT off better than a lower speed with HT on or visa versa. For example, 4.6 HT off compared to 4.5 HT on.

3. Why the difference between prime95 and linx or what is the difference?

OK, I will play with that some also, or do you think I still need to since I've passed linx?




Also, do you guys have any suggestion on how I can bring my vcore down or am I pretty much stuck with where I have it for the 4.6GHz. If so would you say for 24/7 I will need to just bring the speed down so that I can keep the vcore no higher than 4.5?

something to do with LinX and the libraries, it's not testing HT right and is pretty tough to get a 4c/8t or 6c/12t to pass on those speeds. it's been pretty difficult to do with HT on with high cpu speed AND LinX doesn't test 32nm chips at full potential either with HT on. Prime95 has been prooven to pull upto 10% more demand on 32nm chips.

as for your memory. alot of us have found a +2 / +1 different between RTL's gives the best stability. for you i'm not entirely sure i would start at around 57-59-60 or 61-63-64 for 2000mhz on there. for me it's 61-63-64 for 1866 on 12 gigs so you might get luckier with lower settings with your setup. for your tRL's put them all to normal and work your way up or down as needed. though if you're passing LinX with HT off, you really wont need to worry about this. if you want to pass with it on, this MAY help... but don't get your hopes up.
