SB 4.5GHz 1.34-1.35v, want lower

post #1 of 10
Thread Starter 
I'm getting pretty high voltages with my 2600k at only 4.5GHz, which I see being pretty stable at sub-1.30 voltages. I would love to get this chip to clock higher but I don't want to pass up the 1.375v threshold until I get some pretty reliable information back that it won't harm my processor. At 4.6 and 4.7GHz I tend to regularly cross the 1.38v line.

I've got a template that I've seen on HardForum's SB Overclocking thread, so some credit goes there. I would like to know if there's anything here that I can change or if I just pretty much got unlucky with my bin.

Template in the spoiler. Thanks!

There's really no way to lower a stable vcore. However I see people pushing their SB to 1.4volts and that seems like the norm?? The key thing you should look at are your temperatures, as long as your chip isn't burning up your vcore is fine

ASUS Rep " Do you think 1.4V is safe for this CPU? This is a good guide for people looking to overclock.

Yes as noted in my guide. Ideally i would not recommend anything in excess of 1.425 for 24/7 operation while the overall temperature may still allow for additional voltage and even additional frequnecy scaling i do not think it is worth it.

Hope this helps. Please enjoy the rest of your day.

Thanks, BigFrank. I might risk going up a bit just based on that, but with all that I've been hearing about that magical 1.375v limit for 32nm fab, I guess I've fallen for the FUD.

Perhaps if that statement had been made by an Intel employee I would be a little bit more at ease, but I guess ASUS is about as close as we can get.

I checked the Intel site and couldn't find anything. There are a lot of people who run their Chips close to 1.5v if not over. I think it wouldn't be an issue with the SB Cpu's if one has speedstep enabled. If a person disabled speedstep and ran a chip at 1.5v+ 24/7, I could maybe see some issues down the road. I personally would not run it at that 24/7.

Yeah, I think it is important to keep in mind that these chips will probably not be running at these voltages constantly, so spiking a little high isn't the worst thing in the world to happen, as it is unlikely to make much of a difference in the long run.

If you consider gaming for 6-8 hours a "spike" or folding 24/7 on it a "spike" then I guess you're right.

That's not what I meant though. I was sometimes ruling out certain configs because temporarily during Prime95, my voltages would spike into the 1.38-1.4 range. I don't necessarily mean spikes in usage.

Also, for me, 100% usage would pretty much be a spike because I haven't played a game that's as CPU-taxing as something like BC2 and I don't fold, so perhaps we are speaking from completely different perspectives. Your take makes more sense.

Intel stated maximum was like 1.52v.

But does that mean the maximum without royally screwing up the chip or does that mean the maximum without shortening the longevity of the chip by large margins?

I guess I'm asking is that number representative of a voltage that would kill the chip after a few weeks or a month or is it representative of something that will kill the chip a year down the road? I'm looking for a voltage that will still allow me to get usage out of this chip for years to come.

But I guess I took on that risk when I decided to overclock.
