Been unable to bring myself to OC my 2500k and a question

First, the question... why does my system seem slower after I turn turbo on? It's a lot slower, while it's smooth as butter with it off. However, turning turbo on didn't result in much higher temps.

2nd... I can't bring myself to OC my CPU in part because I tried turning on turbo first which made it slower and also because I've just never been an OCer (although I've never had a bad OC experience because I've never overclocked, I'm generally not a risk taker). I think it would be fun to hit a 4-4.2 GHz (4.5 with a better cooler) oc just for the hell of it, but after the system was sluggish with turbo on I decided not to try it.

BTW, I have an Asus Sabertooth P67 in case that helps anyone to answer the question.
 
Overclocking is nice..free speed. There are drawbacks, however, and it's completely up to the individual person as to whether they are worth it. If you are someone who upgrades their gear yearly...don't worry about it. Go for a nice stable overclock and enjoy the speed bump. If you tend to build your machines and use them for 3 years or so, then you may want to stay at stock, at least for a while.

I've built 6 machines over the years, overclocked four of them. All of the overclocked ones started having stability problems around year 2. (My Athlon 64 completely fried itself after two years.) It does shorten the lifespan of the chip. If you are going to upgrade regularly, it doesn't matter much, because it takes a while for it to cause the damage.

I would also imagine that overclocking the Sandy Bridge processors is less risky for life shortening than older chips, since the clock is dynamically changed depending on load...you'll spend most of the time with the chip below 2 GHz, and then it will ramp up to meet demand and run at the higher speeds, so it won't be running out of 'spec' for very much of its life.

I am keeping my 2500K at stock for the time being (just did my build on Friday). I'll probably get a nice cooler and OC the heck out of it in about 2 years though...it'll be a nice way to increase speed without building a new system faster than I generally want to nowadays.
 
Using my Gigabyte OC utility I OC'ed mine to 3.8GHz... very easy and relatively safe. Free speed. I've since then gone in and done a true OC... changing a number of parameters manually without any issues.

Like you, reliability is paramount (mine is also my business system) but I have seen no issues with reliability since OC'ing. I stopped at 4.10GHz, that seems to be my CPU's Happy Place.
 
Maybe your peak current limit is set too low? That might cause some sort of oscillation or contention between the turbo logic and the current limit logic. Or maybe your instantaneous core temps are spiking so high during a turbo burst that it causes immediate throttling. That could be happening so fast that your temperature monitor wont even catch it. I'm not sure if you can log absolute peak core temperature. There isnt much discussion on how exactly the system agent works...

In your specific case, no. You may want to monitor CPU speeds. Intel has a utility which does that, and CPU-Z also does. It is "real time" meaning you have to watch it to catch the speed.
 
Compared to most of the people around here I don't even consider myself an overclocker. But the SB k's just begged to be overclocked. Look at my sig for a really mild overclock that give me quite a nice performance improvement.
 
Overclocking is so common and safe that it is almost criminal not to try it.

People here can provide you with some very very safe settings. They really know their stuff.

I wouldn't try much until you get a better cooler. The stock intel cooler is bad for anything but stock.
 
What kind of cooling apparatus are you using? If you're using pushpins sometimes those pins pop out and the cpu isn't getting adequately cooled and therefore throttles at higher speeds. I'd check on what sort of temps your system is reporting.

Also OCing these chips is pretty easy. The absolute safest way to do it, is to set voltage to normal (normal is the default voltage) in your bios and see how far it can go. Chips will suffer pretty much no harm ocing this way and you should still be able to hit the 4.3hgz range. In fact, if you have time sometimes you can actually overclock and undervolt your chip at the same time. For example, my 2600k runs at 4.4ghz but with a little less voltage than it would with default clocks and default voltages.

To OP.. ive got a 2500k and it was my first OC ever.
you can get to 4.0 on stock settings and still be safe. the only thing at that rate is to watch your temps. just download a tool and run prime to check. very simple and easy speed boost with large gains and very little risk. if you want to read how to do it you just need to Google that. there are tons of simple how to's from trustworthy people on your exact CPU.

I read and got 4.1 on stock settings and really enjoyed it.. so i bought a stronger cooler and bumped it up a little higher 🙂
