I tested again whether mine is a mobo wall or a cpu one and it seems that it is the mobo limiting the cpu.I am so pissed by this 200 wall.It is full of people that manage to post screenshots of 230 and stuff like this and i can't get it stable at 202!!! I never heard of a RIIE having such a low wall.I manage to boot at 209 max and getting into wind raising bclk with turbov upto 210,but it is nowhere close to stability.IBT laugh at me everytime i start it at such speed.i think i was not lucky with this mobo.
And my cpu clocks discretely but besides the fact that i cannot push it as i would like to ,due to bclk wall on the mobo,i think i have not been lucky with it either,since it requires heaps of voltages on vtt to get IBT maxed out stable at 2000.With a Perfect Storm 2133cas9 to be stable at 2000 1T(200*21 cpu) i need(BIOS) 1.66 on vtt(it is about 1.62 real),1,55 on ioh and 1.73 on dramv!!!!!
Not a pinch less in any of these 3 voltages!
On the asus forum i talked with a guy that told that to reach rated speed with corsair dominator 2250 on his R2E he needed 1.7 v on vtt (and he did not talk about stability constraints in a maniacal way as i do).
The G.SKILL tech support admin tested this same kit with a R2E and he told that to reach 2000 stable(again not stable as i mean it) 9-9-9-24 2T at 143(i may be wrong of few mhz)bclk with the same kit he needed 1.5875 cpuvtt.So similar results to me.He blamed the R2E since he was telling that with the same hardware but different mobo(he talked about 2133 rated mobos,are there 2133 rated x58 mobos?)he managed to push the memory to the rated speed...he was not very precise on details of this testing,so i will not take his words like gold but something is suspicious...
It seems that it is definitely not an isolated case.He blamed the R2E ..
So i wonder,am i the only one to require such freaking insane voltages to reach 2000 and over on this mobo,or the world is full of i7920 with crappy IMC?Or really there are many R2E with poor memory overclocking power?
R2E owners let me know if you have been more lucky!
The curious thing is that once i manage to make it stable at 2000 9 9 9 24 1T i can "freely"(without further bumps in voltages) tighten timings to 7-9-6-20 1T.smth is definitely wrong...
i never managed to reach 2133 even using 133 bclk and any amount of voltage.The most i got IBT maxed out stable is 2088 with bclk130*21 with these settings 9-9-9-24 2T
vcore 1.375 vtt=1.75!!! ioh=1.55 dramv=1.73 and the rest at stock besides little differences due to the bclk being 130 and not 133...
I want to cry.I spent 400$ for this mem kit(here in europe) to find myself forced to lower ddr3 multiplier and use 1600 speed for 24/7.
@Criptik : Your cpu vtt requirements are amazing low.

Just one quick question,
what's this cold boot problem all about?
Because Im experiencing this problem here:
Whenever I turn on my PC, it shuts down after a period between 30 sec to 5 min...

I have 9800GX2, 3GB ram 1866 Corsair, Corsair 750W, and i7 920 oh yeah and 2HDD's in raid0 SATA.

I don't wanna overclock, I just want my computer to boot into windows, that's all I'm asking!!!

Think im gonna hit the shop monday or tuesday, is it possible that something blew up?

Seems a power related problem(mobo or psu).Are you running everything at stock?(memory included)Did you notice if it occurs when you start to load the system?ANyway the cold boot problem is not the one you are experiencing.COld boot problem is what the word itself says.Once you power on the switch of your psu and you boot your system,it won't boot,you reset it and it will work.

Nice one, looking forward to it.

@Criptik : Your cpu vtt requirements are amazing low.
Without a CPU tested stable at a higher BCLK, there's really no way to test your board's BCLK ability AFAIK.

I think there is a lot of variation in CPU IMC abilities based on what I've seen. DDR3-2000 is hard on any CPU though. Personally I have not tested quite that high, I've only gone up to DDR3-1965 MHz @ 7-8-7-20 1T which required 1.634 vdimm and 1.343 Vtt - you can see from my post on the first page that Vtt scaling starts to ramp up fast over ~DDR3-1934 MHz at 7-8-7-20 1T (with my CPU anyway). I am quite surprised at your vIOH requirements, IIRC I was using around 1.11v for DDR3-1965 MHz, and same for 200 BCLK stable.

That's not a 'cold boot' issue per se, cold boot problems refer to the board becoming unstable when turning it on after a full power off at the PSU or power outlet. For that issue, BIOS 1504 should help, but some guys still reported issues with that BIOS.

If your board just shuts off completely after power on, something could indeed be damaged, or you could have a short between board and case or board and CPU backplate/water block etc. I'd re-check everything, and if the issue persists, pull the board out of your case, remove any backplates/blocks etc and run it out of the case to see it it works.

The cpu is fine upto 4.2(200*21). lowering the multiplier, if i don't manage to get past 200 bclck,it should necessairily be the mobo.At least this is what i always experienced.
Anyway your vtt requirement are very low,even if they ramp up over 1934.I managed to get
only slightly lower voltages(compared to 2000 ones) to get at 1934(between 1.55 and 1.6 vtt with 194 bclk).IOH was needed to stabilize with IBT.Many need to raise that high when close to the limit.
Anyway the ioh i use for 200*21 @ddr31600 is 1.16 so very low
it is going up with the memory (>=2000),and from what i experimented this afternoon with bclck,that calls for NB voltage bumps,when wanting absolute stability

I've run the motherboard outside the case, nothing changed.
I've tried the 1 bank of memory a time trick, nothing changed.


http://tinypic.com/r/2uzf4u8/6

Heres a link to what I experience most of the time,
sometimes i get past POST and to the login screen of Windows, and then it shuts down,

Any help is really appreciated

For me it is a power related problem , something with the psu or(and) the MoBo.
Did you try with another psu? If u don't really have any other way to check the components separately,you could try to connect the psu to a 12 v device,like a car hi fi or anything else that can load at least 100-200 watt and see if it can keep up with the load.The best of course would be another pc ,so that you don't have to mess with wires and stuff like this.
If it works you can exclude the psu and say that probably it is the mobo. BUt again testing the components with another system would be the best idea.
Unfortunately when we don't have any other system to test things,it is hard to say what is the origin of the problem.I sincerely hope it is your psu....
Another thing that would give a clue and address the origin of the problem to the psu is whether ,when your system turns itself automatically off,the leds of the mobo remained turned on or off. If they remain turned on it is more likely to be a psu stuff.SOme blown capacitor could prevent you from being able to keep up with even little loads.
Good luck!
I fyou want to plug smth to your psu ,to test it ,you have to short the green with one of the blacks (using a wire)of the mobo connector(the 24 pin one).Then you plug two wires to a yellow and a black one (of the 24 pin)and you use them to feed a 12v device.A car hifi would be the best,but anything that can absorb >100 watt fits the case.
