I7 2600K I probably didn't win the silicon lottery.

Hey guys, Just looking for some advice, I've had my cpu overclock at 4.5ghz for about 3 months now at about 1.38v with a maximum temp for about 58 degrees. I wanted to just see if I could squeeze some more out, but It fails the Intel Burn test on "very high" at 5ghz at 1.46v. Was looking for some advice on what this forum considers dangerous voltages for sandy bridge. I'll probably get another cpu within 3 years, but I'd like to be more cultured at cpu overclocking. Thank you in advance! I have a feeling though that my chip just isn't the cream of the crop.

At 1.46v I only reach 70 degrees.

Keep it below 1.4 mate. 1.38 is a tad high but your watercooled so heat isn't much of an issue. What speed can you get at 1.35 volts?

 

[GregPalos]

I brought it down to 1.37v, going to try at 1.36v. new photos up.

Good lad. You shouldn't see to much of a difference, especially in day to day use. 1.35-1.37 is good, any higher and I wouldn't want it to run at that 24/7.

 

[GregPalos]

do you know much about gpu overclocking could you look at the image and, give me a bit of background knowledge on if i've done it right?

 

[SavageCupcake]

I've not much idea on gpu overclocking mate, especially not the new nvidia cards. Maybe someone else can help you with that one.

anything over 1.4 for longer than the occasional bench run has shown to degrade SB CPU's somewhat quick. As said 1.3 to 1.38 seems to be a spot they're happy with. I run mine at 1.36 for 4.5Ghz and its been there since I bought it 2 years ago. I did bench it once back them @ 5.3Ghz with 1.6 vcore but it was a single run just to grab a score.

Those I read about degrading did so quickly for fools who just had to have 5Ghz and crammed 1.45 or higher volts and then soon found their beloved chips no longer ran stock at higher than stock vcore. By quickly I mean within a few weeks to a couple months. So if you plan on keeping it 3 years then stay under 1.4 and just get the lowest vcore you can @ 4.5Ghz cause normally after that you have ti hit 1.45 or better to get stability.

haha, fair enough. I understand. Just some other people were misinforming me that anything between 1.4-1.5 was fine temps wise for sandybridge. Do you know much about GPU overclocking?

 

[S_I_N]

that is correct on SB 1.4 -1.5 doesnt affect temps like it does in IB or Haswell but cpu degradation isnt just a fault of temps vcore play alot into it as well. in the past as long as you kept it cool enough you could crank volts, then they started seeing the vcore also degraded the silicon as well. Thing is the cooler you can keep it the better off you are at stopping the degradation at higher vcores. So if you want 5Ghz and want to push vcore invest in a phase chage unit for below ambient cooling it might stave off the degradation a little longer. but at 600-1000$ investment most dont do it. Plus it adds to the boot time of your rig as it has to cycle til cool enough to boot at the higher settings lol.

holy just researched that. Thats crazy!!
