The Rampage always throtteling ;) The Rampage need Watercooling to perform well, the Dark is much stronger.

Simple question is the Dark worth the money, I had a EVGA Classified X79 and it was broke from day 1.  Everything else I own in my pc is EVGA just wondering if this is worth the purchase or not.
Thanks for the input

Based on your sig you have a RIVE, so what gives to want to go DARK ?
From my part with 2.07 overclocking and usage of the DARK has been a breeze. 2.02 was good, 2.04-2.05 had it's issues. 2.07 is great so far. K-Boost disabled and clock 4.2GHz v1.25 on my old 3960X without much sweat. Vdrop 80% which is fantastic. 4.4GHz haven't tested much yet v1.35 was a little too high. Aiming for some lower voltage.

manojks, You have your "Vdrop 80% which is fantastic" set in the Bios to 80%?

Ok I remember that post. It just sounded very cryptic and not detailed or clear.
 
I need to find a way to run with Kboost disabled. I'm worried about the spike.

Jacob said there should be no adverse effect to the CPU with having it enabled and that it is a feature to improve overclocking with the VRM circuitry. Either way I wouldn't worry about it so much, it's not like anyone is not going to just RMA the chip to Intel if by some freak chance it does get killed. You can even buy Intel's overclocking protection plan if it makes you feel better and then just shoot the volts to the sucker lol.

I can only confirm this:
 
 
- with Corsair 4 x 8GB 2400MHz system doesn't boot into BIOS or Windows
- with Kingstone 4 x 8GB 2400MHz system works ok with default settings or with XMP 2 2133MHz... with XMP 1 system doesn't go to BIOS, it's just restarting over and over again after 4-5 seconds.

VDroop = Voltage droop , if DISABLE it voltage will rise in heavy load durring stres bench/test etc...this value varies from your voltage in bios set to almost +100mv(0.1v) depends how heavy stress test is( prime95/ibt/linX /intel burntest etc..) so the real voltage aplied to cpu with this option DISABLE is NOT the value that you in bios set , this is only idle value durring os load or something sligty load.

VDroop = intel specs = Enabled , this function will droop the voltage in heavy load , you set in bios a vcore  value , boot ~ with that value but in load voltage will droop 40-50mv ( 0,04-0,05v)
VDroop = 60% - 80% this function enabled vdroop in voltage precentage ...i used always VDroop -80% because the value idle/load is the most accurate with reality on this board ...not perfecty because evga bios team haven´t implement vdroop-100% /120% to calibrated the pwm better ..all voltages onthis board is very unaccuracy not only vcore

 
Thank you!

To the guys working on the BIOS:
 
I've been using this memory: 
and I cannot boot with the first XMP profile for 2400MHz and have not been able to since the first bios. The XMP profile is not being read correctly for this memory (at least for profile 1). Profile 2 at 2133MHz boots just fine since the first bios.

Using the exact same sticks and same issue. Tried a 4x4 aswell same.. 3 diffrent boards..

Just got done with some OC testing and man I have to say this is a solid bios.
 
I was able to get:
 
1) 4.75GHz (Mult = 47, BCLK = 101) with PLL enabled, Kboost enabled, Vcore = 1.35v, and Vdroop disabled. Resulted in voltages as high as 1.45 shown on ELeet so this is a bench only setting for me.
2) 4.7GHz (Mult = 47) with with PLL enabled, Kboost enabled, Vcore = 1.30v, and Vdroop disabled. Resulted in voltages as high as 1.399 shown on ELeet and I'm comfortable using this as a 24/7, but prefer lower volts.
3) 4.5GHz (Mult = 45) with with PLL enabled, Kboost enabled, Vcore = 1.265v, and Vdroop at 80. Resulted in voltages as high as 1.290 (on idle mind you, load is 1.265) shown on ELeet and I'm very comfortable using this as a 24/7.
 
Unable to get 4.8 with a 48 multiplier IBTv2 (Intel Burn Test) stable, but boots fine.
 
Disabling Kboost on the first two result in the same error that dustingg mentioned (WHEA_UNCORRECTABLE_ERROR). But very happy #3 works without it. Maybe Kboost is necessary for high voltages? I'm really impressed with my minimum voltages for my #3 though. Seems too low... But if it's accurate, I'm pretty happy.


Ended up getting the same error for #3 from a cold boot the next day with Kboost disabled. Booted up just fine with it enabled so I guess I'll have to live with it.

Biggest thing left is more options for Vdroop and having the ability to have offset voltages and fix the XMP profiles for the Kingston HyperX Beast 2400, but right now I am extremely happy with this board. Exponentially happier than I was with 2.05.
 
Props to EVGA. 
 

Just to clarify: if I leave K Boost at its default, and have not OCd the CPU, then it has no effect - my CPU isn't getting spiked? 
 
Thanks!

 
I have 4 x 4GB Corsair Dominator Platinum 1866MHz ram [link] and XMP1 is now giving correct timings, voltage etc. for this ram with BIOS 2.07. Thank you. I have not started clocking the CPU back up since loading the new BIOS.. will advise.

K-Boost only takes affect when above 41X multiplier.

Whit 2.07 my system hang when i don t touch the pc for a while.
i have kingston beast 2400 and i try all the setting possible. i dont know if its the memory.
thanks

My system hangs sometimes when I'm in BIOS, even if I do nothing... just scrolling through the menus. Otherwise achieved 4.6GHz, 1.4V stable (over 12h prime and linx) and 4.7GHz also stable, but with unreasonable voltage over 1.5V

I am using the G.SKILL Ripjaws Z Series 16GB and have not yet found a way to set them past 1333... Kind of frustrating actually. Does not matter what I do with the CPU (Including stock bois settings) they simply will not run at the XMP settings...
 
And every time I do update the bios... I have to remove three of my four drives so that the BIOS will see the drive with the OS on in and not error "Hit any key" at startup...  The BOIS defaults to the top drive on my setup, and my top drive is a storage drive. Not able to see all four drives at the same time in the BOIS thus far...

lol I have the worse Ivy Bridge as chip. 1.47v to get to 4.6GHZ. I have Hyper Threading on though. Temperature with my water cooling is 70 degrees on load. Still haven't fully tested for stability but it works for now. =-/

That is an outrageous amount of Vcore for that clock speed bud...

Yeah it is. I was getting lots of BSODs. The reason is because my memory is faulty. Got lots of errors on Memtest. I'm exchanging my G.Skills to some Corsairs. I kept raising the CPU Vcore thinking it needed more. Maybe once I get memory that actually works my overclock won't need such a high vcore when I test it again.
