Hello people of the PVKII community!
I decided to create a new post to show off the OC I managed to reach, and to what volt values and temperatures in Celsius
Motherboard: N/A (Don't remember.)
CPU: E8500 Duo core @ 3.70 Ghz OC (3.16 stock.)
GPU: Nvidia 460 GTX (<-- Never bothered to OC before now, alongside other new components.)
RAM: 5gb (Mixed chips, 2x2gb + 1gb.)
Cooler: N/A (Never knew the name.)
New spec after christmas:
Motherboard: Asus P8Z68-V Pro
CPU: i7-2600k @ 3.40 Ghz
GPU: Nvidia 460 GTX
RAM: Corsair Vengeance, DDR3, 1600Mhz, 16Gb. (Latency: 9-9-9-24)
Cooler: Noctua NH-D14 (Still argueably the world's best air cooler, holding title three years in a row.)
After I installed the components, I wanted to see how far the 2600K would reach on stable levels using prime95 (http://files.extreme.../file.php?f=103).
I hit 4.0 Ghz easily enough at 1.14 voltage (Vcore), and turned it up a few notches to 4.5 Ghz at 1.25v, stable. From there, things got interesting. My CPU at that time wouldn't want to go any higher than 4.6 Ghz at 1.25 ~ 1.29 volt, and later I was forced to increase the voltage again to 1.30 ~1.31v and once again to 1.34 v, steady as rock (prime95 ran about two hours after four, five BSoDs as I was climbing up).
My idle temps were around 28 - 31 Celsius degrees, which is quite good. However, I wanted to go higher. My goal was 4.8 Ghz, but no matter how much I increased the voltage, it just wouldn't let me get away, and I wanted to avoid anything much higher than 1.35v ~1.40v (+,-), because as we all know, The Sandy Bridge (Which is, by the way, intel's codename on the project) CPU's are made from a 32nm process, which means they are basically made up from a thinner slice of silicon than earlier chips. In theory, that means the more voltage and heat you run through them, the more susceptible they may be to degradation over time, if we are comparing them to their 45nm or 65nm predecessors.
Fortunately, and by unknown reasons, today I tried to increase the core clock again to 47, multiplied by all cores of course, and I managed to boot. I have no idea whatsoever how that happened, but I was happy. I tried again after watching a youtube video of Skyrim in HD with Bethesda's new texture pack, and the uploader had listed his spec. He was using a i5-2500k at 4.7 Ghz, at 1.35v (No idea if that was steady or not, but alright). That was provoking to me, so I went back into the EFI Bios and booted at 4.7, then later, 4.8 and 4.9 ghz! Only with a voltage increase from 1.35v to 1.37v
You can already guess what the next thing I did, was...
I was going for 5.0 Ghz, steady or not.
... Increased voltage to 1.38 .. didn't boot.
... Upped to 1.39v ... Booted, but system crashed 10 seconds after my screen was done loading.
1.40v... and boot ! I was in awe However, crashed a couple of times later when running PVKII. Odd, since I already ran Fallout: New Vegas with my customized tweaks without any crash. I ended my hours of testing at stunning 1.42v, temperatures of incredible 28 - 35 Celsius degrees. Did I mention Noctua NH-D14 is the shirley?
*These print screens were taken with a room temperature of 19.3 Celsius.
OC'd the GPU to 902Mhz at the core clock speed and memory at 1875Mhz as well.
So if you have any questions, please ask. And of course, post your own overclock results below. How far have you hit?
