My quest to 5GHz on i7 2600K, should I continue? - Page 6

post #51 of 107
ok, at 1.47v you should not be getting a BSOD can you take screen shots of your bios settings, im sure something else is amiss here. is your PLL over voltage set at extreme?

Although, I did 12 hours in small FFT (first prime test) with CPU C3 and C6 disabled. Would you consider it stable @ 1.415v or should I run the blend with the custom 14745 RAM? My highest core temp in small FFT averaged 74-75, lowest was Core#0 at 67-68 average. CPU was at 64c pretty much the whole time.

Yeah that's a great long term overclock.

You won't notice any difference between 4.8 and 5ghz. Trust me I've had this chip for a year, to this day I cant notice any difference in everyday tasks

I have heard of windows getting corrupted due to BSOD, I have never experienced it myself however and I have been overclocking since 2006.
Just got to overclock smart, if you try an overclock at a certain voltage and it BSOD's soon as it hits the desktop, you should raise voltage by a lot more than you would if it BSOD after 4-5 hours of prime95 blend.
1.you have an amazing chip! If you ever wanna get rid of it gimme a shout wink.gif
2. Couldn't agree more 4 sticks make it much harder to OC as per my experience with every CHIP since first generation dual cores. But Sandy Bridge has been the most difficult to work with when running 4 sticks, I spent a long time tweaking to try and get it stable, it just wouldn't budge. And mind you I was only running ram at 1600Mhz, I can only imagine how much harder it would have been at 2133

Lol, im running 4 sticks at 2133 tongue.gif

Great news. A little dissapointed I couldn't get to 5 but it's okay, i'm happy with my 4.8 long term rather than god knows when it'll degrade 5.

Is there any way to delete all those BSOD files somewhere? Honestly unwanted space on my SSD if they go somewhere. I had about 12 or so today just trying to stabilize it at 5.

0.04v - 0.05v is more the norm for every 100MHz that high up. You'll probably find that you need 1.5 - 1.52v before you're stable at 5GHz, which is not recommended.

And the reason temps spiked at 15 minutes is because the first test ended (FFT 448K) and the second began (FFT 8K), which runs much hotter. If you'd notice in the custom options, you can change the test length for each FFT. The default is at 15 minutes. If you're doing short tests to zero in on a voltage, you should use ~2.5 minutes per FFT instead of 15 minutes. You'll BSOD much sooner. Likewise, if you're shooting for 12 hours stable, you should change the test length to about 10 minutes so that every FFT is tested. 15 minutes requires 17-18 hours to test all FFTs.

A lot of the questions you have asked made you sound like a troll because you're making too many assumptions, such as saying you tested with prime with c3 and c6 disabled (this doesn't matter because c3 and c6 aren't a factor when all cores are loaded). You should try to take the information you've already been given and use it.

It isn't that hard to reach 5Ghz with a 2600K, just bump your vcore up to 1.48v and you should be pretty much right in the ball park for stability if your cooling can keep the temps in check.

You do realise the chip start degrading when u bump the vcore and 1.48 is a lot more then (1.38-1.4 intel suggested limit) its not about the temp at this point the voltage itself .

Im pretty sure 1.48 is not safe for 24|7 usage on SB

What i'm wondering now is, why I have to have at least 1.4v to have a stable 4.8ghz overclock while I see people stating they have it stable at around 1.3-1.35v sometimes lower. I know I need a bit more vcore because I have 4 sticks of RAM, and 1.4v is a healthy overclock but geez, how the hell are they getting stability with that low of a vcore?

The silicon in their chip is able to handle higher speeds with less power, it's just luck.
