Hey guys,

So I finally had the time to overclock my 2500k. I was able to push it to 5ghz (50x100) @ 1.45v (under load in CPU-Z) at only 60C after an hour of Prime95 Blend. Is this acceptable for a 24/7 overclock? I don't fold or anything so it won't be under stress unless I'm gaming or transcoding a movie to my PS3. I also passed 10 rounds of IntelBurnTest and OCCT for an hour. I believe the max volts for a 2500k is 1.52v so I feel pretty comfortable. My PLL voltage is 1.709v.

What is everyone's opinion on this? Is this safe for 24/7 usage?

Thanks again,
Matt

Do you have Speedstep enabled so when its idle its at 1.6Ghz? If so then this OC should not be a issue since it wont run that voltage and speed 24/7

I tell ya what...for me, your voltage is too high. 1.41 max, please! Sure Intel says 1.52v, but that's not for Full-core load, nor for OC!

But, buy a OC warranty from Intel, and your chip will be replaced. SO give'er the gusto, man(note that you must wait 30 days after buying the warranty online before you many submit a claim...so buy NOW!)

I won't put more than 1.38v through a SB chip 24/7. I know that Intel says 1.52v is max, but I've heard many accounts of degrading chips over 1.4v. So, I will clock the hell out of a chip, bench it up to 1.52v to see what it's capable at the top end, then down to 1.38v. Whatever I can get at 1.38v is my stable 24/7 clock. After more than a dozen chips, this has been the best course of action.

@brandonwh64: Yes, SpeedStep is enable and it downclocks and goes to like 1.06v.

@cadaveca: I've considered buying it, but I've done a little more research and there's people that have been running their chip at 1.5v for 6+ months 24/7. I think my cooling is adequate enough to handle the voltage and I don't think the chip will suffer too much.

So then why ask? :rolleyes:


:roll:

Like really?

Have I personally seen chips degrade with just a hair over 1.4v YES!!! Were they hot? NO!!!


Do what you will though. It's NOT about cooling. I dunno why everyone thinks it is. Unless you are running @ -40 or lower, this whole idea is invalid.:laugh:

Degradation does not always come from heat. ;)

I know that it's not about heat, been overclocking for a long time. I'm basically asking opinions because they seem to vary everywhere I look. Overclock.net users say 1.45v is safe for 24/7 usage. Here people seem a little less lenient.

Oh, I understand that. Trust me :)

I don't think you do. These chips barely eat 150W. It's nearly NEVER about cooling with these chips. 200W of cooling, to get sub-zero, is a cakewalk. And yes, that's all it takes tp go negative with these CPUs.

Maybe I will play with it more when I get home from work and try for my highest clock at 1.4v.

Oh, I really do. Been overclocking since Socket A days. So please, don't try to insult me. I've never had a chip die on me no matter what I pumped through it.

It's not an inslut. I'm sorry if you think so. Really.

But fact of the matter is that it's $20 bucks for the warranty. If you're gonna go over the 1.38 that Paulie recommends, buy it, and forget worrying about it. There have been CPUs that have degraded or outright died with less than 1.45v.

It just doesn't jive with me that you'd claim to know what was up, but then ask the question you did, and hence my comment. It wasn't meant as an insult at all. If ya wanna take that angle, if you know, then ask the question, then what are you asking for? As a troll?

:laugh:

I mena, I've been clocking just as long(longer, actually), but I don't know nothing. Tech changes too fast for me to keep up.

It might not jive with you, but professionals in every field like to get more than one opinion other than their own even if they've been doing something their whole life. Asking for opinions does not mean someone has no idea what they are doing.

It does when you immediately denouce those opinions because they do not agree with your own.


Like don't take this the worng way at all...just having a discussion here.


But tell me something..do you think these chip clock at all like anything that has been released before?

I wasn't denouncing anything, just stating that other people have said 1.45v, 1.5v, etc. Why should I value any one person's opinion over another's? I'd much rather have a ton of opinions and average them out.

Because these chips act so differntly than previous chips, you bet I personally have been paying even more attention. I've already gone through over 30 chips myself. Over 1.4v CAN be dangerous, and of course, there are some outliers that are perfectly fine with more...but not every chip will be.

Hence my suggstion of buying the warranty. If ya didn't get some luck with your chip, then i think it's better to be prepared for the worst, but expect the best.


I don't really think you'll killyour chip..but yes, these is a good chance you could, so I advise with safety in mind.

These chips easily reach speeds that would take previous generations much more work to reach, if they were even attainable with those chips. I remember getting 4ghz on my Q6600 and that was an accomplishment.

However, these chips also have a higher starting clock than older generations (pre P4 era). If you're asking about a percentage based overclock, then yes. A lot of chips could reach 50% overclocks, etc.

5+Ghz is the holy grail and all but I too wouldn't go over 1.4 and think Paulie's initial advice is the best.

NO, what i mean is that these chips have multiple power planes, and different types of transistors that have much different tolerances...in the same silicon. Parts of the chip can take 1.4v, others can blow if you give more than 1.25v. And these parts are on the same die...

When I get off work tonight I will see what my highest stable overclock is at 1.4v since that seems to be more a reasonable voltage.

Ah ok, I was confused by the question. You're talking about the double-gate transistors and what not. Yeah, I know they are completely different and have different internal power requirements.

Ivy bridge is tri-gate. Confused myself for a second.
