**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)
- Thread starter Gibbo
- Start date
same as me
I found when I hit the wall with my Vengeance, just took vdram to 1.7v
just to find out what it needed.
Then worked backwards, isn't the Sammy good upto 1.75v ?
2400 looks out of the question, can't get it to post even at 12-15-15 at those speeds, 2200+ would be nice as I'll be base/strap clocking 
Might have to give the big fella a shout to see about getting the CL and CR down though.
At 10-11-11-24-114-2T at the moment, so certainly making huge progress over the 11-15-15-40-180-2T I could manage before.

He helped with my Plats, only prob is my Vengeance scores better
Got my Vengeance 2133 from 11-11-11-30 down to 9-10-10-21. 
Couldn't OC for nowt
but tightened everything right down gets me around 17000 physics points @ 4.9Ghz. so not that bad
Still playing with the Plats but I'll need more guidance from the man

That's what I read too, but where's these official Intel specs? I've never seen them. A lot (including 8pack) are saying that over 1.2 will accelerate degradation quite a bit, although I read somewhere else that the 3820 is safer for higher than the hexcores. Still, that's up to us to decide isn't it.
Did you try a higher BCLK like 128-131? I was able to drop the PLL to 1.65v and reduce vcore a bit that way. 128.25x39 is stable with 1.4vcore on mine.
It sounds like your IMC isn't playing ball with higher RAM clocks. I'd be going for lower mhz and really tight timings, the difference in performance is negligible and the reduced load on the IMC is worth it IMO.
Yep, I'm only going for high speed/tight timings for benching, the 2400mhz kit I had was held back by the fact it didn't like CL10 even at 2133mhz, so I'm already doing better then that
The rest of the time I'll have them ~2000mhz tight on a 4.75ghz clock.
I'll be moving onto the base and strap after I've settled on some timings at 2133mhz I'm happy with, still getting some minor adjustments as its now 10-11-10-22-96-2T, doesn't seem to like 1T regardless of timings
Though it seemed LTMatt had the same issue with 16GB on P67, just didn't like 1T.

Slacken the middle ones to 10-12-12. Mine are much happier like that. You're working on them in the wrong order really. Do CL first, then go for 1T, then tRFC and finally tighten the others.
Thanks for the pointers about order, I was just working them back randomly from the auto setting.
This board is nuts though with the auto timings, 100 base 1.0 strap, stock everything, memory auto set to 1600 CL11, set to 128 base with 1706mhz it auto sets to 9-9-9-24-1T!
Working on the base now. So CL, CR, tRFC first in that order then worry about the rest

I can't take any credit, that's 8pack's advice. All I know is it saved me a load of time messing about! That's basically the order you'll get the performance from on Intel. On 990FX, tRFC and CR was less important.
He's said a few times about the 'ramp and flat' too with this RAM. 10-12-12 rather than 11-11-11 if you get what I mean.
The higher BCLK is his thing too, it's in his X79 OC guide. Everything I found that he suggested has worked out on my set up, that could just be coincidence you know!
I am using an ROG board too which is his thing I believe.
One thing I found for myself was that the IMC wasn't stable in IBT on maximum just over a couple of runs. If it did two runs on that (~15mins) it was good. The same for RAM settings. Also it won't complete SuperPi32m if it's no good.

Yeah I recall him saying something along the lines of Samsung start flat then slope, starting with CL is working a treat so far for my 24/7 clocks, results soon (i hope!!).
Edit: I Officially give up, this stuff can go on the MM
Getting it to post is one thing, getting it through memtest is another, 2000mhz, 11-12-12-36-2T, 1.4v SA, 1.4v VTT, 1.45v CPU, 1.675v DDR and gave me 1500 errors by the time it hit 6%. I quit, I'm done.

Did you go straight for a higher SA and VTT? I mean have you tried to see if it will post with ~1.2v? Just wondering if the higher voltage is having a negative effect on the IMC.
Soldato
Does your mobo give you access to the seconds and thirds timings?
Soldato
The Asus preset that 8Pack suggested I try set all the seconds and thirds tighter and then it wouldn't even boot with previously stable mains, so it could well be you have that sort of thing going on.
