i7 3820 - 4820 Overclock Club - Page 44

Here's my settings on my Asus Sabertooth which gives me a stable (IBT at Max x 10) 4.8GHz. People will flame me for my voltage but I don't get the obsession with getting the lowest voltage possible (unless you work for Greenpeace or care that your CPU might die in 15 years instead of 15.5 years)...

448

Obviously the RAM settings are for my kit, you may need to change these for yours!

You need to turn off your C-states and intel speedstep if it's on. They are downclocking your multi as displayed in your CPU-Z SS (x12). Also, there are two places in the bios to enter the multi. There's a max turbo area and a non turbo multi, they are probably offset from each other by one digit which is causing your unexpected multi. Take a gander at the Sandy-E OC guide thread to read up a bit more on this.

Heya Man - I hear what you're saying on the VCore but holy smokes bro.........bigeyedsmiley.png 1.44v at 4.8Ghz?? I know you'd be stable with far lower than that. I've settled on 4.75Ghz for every day use and I'm already down to 1.355v stable as a rock. Not knockin it, it's your rig homie, but daaannnngggg.....just say. wink.gif

edit....I keep posting the wrong vcore

I'm about a week straight 4.3 Ghz at 1.232 Vcore. Done folding and gaming, never a hiccup.

http://www.overclock.net/t/1221208/i7-3820-overclock/370#post_16917502

CPU-z says 1.24. 1.232 is what the Asus AI Suite says.

I have the Evo model with push/pull. It works great, AND it clears both sets of RAM.

I'm completely new to OC'ing and all I did was increase the Multiplier of my i7-3820 to 43x (using the ASUS Windows software) and it failed the Prime95 torture test in just 1 hour and 10 minutes:

361
(mirror: http://i.imgur.com/zZaTH.png)

Everything in the BIOS is running in the default settings EXCEPT that I've enabled XMP profile on my RAM so it would run at its intended clock speed of 1600.

Specs:

Processor: Intel Core i7-3820
Motherboard: Asus P9X79 Deluxe
Case: Cooler Master HAF-X
Fan: Noctua NH-D14 SE2011
RAM: G.Skill Ripjaws Z DDR3 1600 16GB 4x4GB CL7 (Model #: F3-12800CL7Q-16GBZM)
HD: Samsung 830 SSD 512 GB (Model #: MZ-7PC512D/EU)
PSU: Seasonic Platinum 860W (Model #: SS-860XP Active PFC F3)
Graphics: PowerColor HD 7950 PCS+ 3 GB (Model #: AX7950 3GBD5-2DHPP)


Am I doing something wrong or is my CPU stuffed? Any other insight?

Many thanks!

What you are doing wrong is not using the bios. OC software sucks sofa king much

Ditch the OC software, go to bios, set multi to 43, set vcore to manual and try starting around 1.25-1.30 volts. Always OC in bios.
