Looking to run faster

post #1 of 39
Thread Starter 
I'm currently stuck at 4.5GHz which is not bad, just not great!

I tried to see if my 2600k would do 5.0ghz and didn't happen, I tried with 4.9 and vcore on auto just to see what would happen and inside windows I saw massive vcore on cpu-z like 1.7+ , so I rebooted instantly and tried to see if i could run at near 1.5, I did 1.495 and I had trouble with stability, I did not want to go over 1.5 seeing as my last boot on auto scared me!


Is there anyone who can help me see what my i7 will reach? Do I need to keep going from 4.5 to 4.6 to 4.7 or can I make the massive jump to 4.9/5.0 and try to see if I find a vcore that works? I know for a high clock like this I will need to change other settings and I am fairly new so I have just been trying to search the forums!

If you cant reach the overclock you want by staying under 1.4v and 80c not much you can do and you dont have you system specs up so its hard to help

i tried to do the rig builder but it wont find some of the items i manually enter, i asked some people for help but I gave up frown.gif I have my system water cooled so it stays very cool, its just my cpu in the loop

i see so many people above 1.4, do you think they did it for just the thread or run 24/7?

Sorry for the noob questions! Is 1.4 the max safe voltage for this SB chip?

You can do 1.45V with no problem on a SB, and lots of guys have done 1.5V for long periods (although I would stay below 1.45V myself). You might not get 4.9 or 5.0 with 1.45V, I'd try 4.7 or 4.8 first and see how that goes. Once you get above 4.5 or so Auto Vcore becomes unreliable, so you'll need to set it manually, and you'll probably need a pretty high setting for LLC as well. You also might need to enable Internal PLL Overvoltage, if it isn't already.

Hey Forceman,

Yeah I tried but when I set 1.495 and it wasnt stable at 4.9ghz I got really scared, I know this has to do with other things like me leaving PLL and the other settings on Auto.

Is there a true "safe" voltage that won't degrade the lifespan of my chip and disqualify it from it's warranty?

I'm going to try for a 4.7 or 4.8ghz, at this rate I'm not sure if a few hundred MHz is worth the voltage im feeding it right?

There isn't really a "safe" votlage, there are just differing levels of dangerous. I haven't heard of anyone having problems with 1.45V, and even 1.5V seems to be safe considering people have been runnig that voltage since the chips were released. I wouldn't feel comfortable at 1.5V, but as long as you keep the temps in control (which would be hard at that votlage) it should be fine. The way I normally do it is pick a voltage I am comfortable with (and a temp) and then just run whatever overclock I get with those limits. I worry less about it that way. So for me I would be fine running 1.45V in the low-80s under full load, but it turns out that running that high only got me 100 MHz over my normal overclock, so I just dropped back down.

If you find the point where the chip starts taking a lot more voltage for small gains (and all chips hit that point) I would just stay on the low side of it - so 4.7@1.35V is a lot better for me than 4.8@1.4V or 4.9@1.45V. Those small speed bumps are not very significant, but the voltage and temp bumps are.

You can normally lower the PLL voltage and VCCSA voltages a little bit once you get stable to help the temps - they don't usually affect stability but can drop temps a few degrees.

It shouldn't matter if it finds the item or not. Half of the ones on my rig weren't found. You should be able to continue anyways.

Are you trying to find your max multi or just a high 24/7 overclock?

Best way is just to say put 50x multi in and 1.35v, see if it boots, if not increase cpu vcore until it boots, then start using prime95 to test stability. And once it fails p95 increase cpu vcore. Rinse and repeat!

I thought reports of sandy bridge degradation were rather widespread above 1.4v?

Over 50% of ivies and sandies can only do 4.5-4.6ghz on less than 1.45v. That's just the silicon lottery. lol at trying to hit 5ghz, maybe you should have binned your chip before wasting money on all that water cooling.

Here's what you do OP - boot at 1.3v. Use softwate to overclock your CPU frequency incrementally from 4.4. If you can get to 5ghz, then you got a decent chip and it'll take a ton of voltage to hit 5ghz and might not be safe but you might have a chance. If you can do 5.1, 5.2, then you got a good chip. Most likely you can only do 4.6-4.7 without freezing before you can increase the multiplier again, and you got a bad chip like most people did.

why would you do that? You have to have a one in a million chip to be stable at 5ghz@1.35v, OP definitely cannot do that if 1.49v is not stable at 5ghz.

OP you would need to be very lucky to be able to do above 4.7ghz on sandy/ivy. And you are pushing voltages that have been known to degrade sandies instantly. I'm not too sure but ivy degradation and death is unheard of, but sandies degrade all the time and tons of reports of people's chips dying out.

@lostmage
thanks mate, ill be finishing this up tonight, I figured I shouldn't save my info if all the parts were not showing up

@silent
i found out about the forum with the sandy bridge thread, smile.gif
I immediately posted my 12hour results of my 24/7 clock
i was just curious to see if i could max my chip out

@belial
i would have purchased water cooling regardless
i found my oc before I purchased the kit which was 4.5 so i didnt waste any money mate smile.gif


So I'm done, It seems at v1.45 is the only way I can get 4.7ghz stable , i hit low to mid 70-75C and I am not comfortable.

It was v1.365 4.5ghz vs v1.450 4.7ghz
while I love the 200mhz increase, for the temperatures and voltage I do not think it is worth it. I am amazed at how IB's clock though!
If I knew I could run 1.450 without any degradation vs 1.365 I would do it, i am a bit skeptic so I must sit back and just watch the others do it smile.gif

forgot to mention! thank you all for posting and helping me out, seems this forum has a great big community smile.gif I'll be doing much searching and researching with the past threads!
