2500k OC, reasonable?

no experience of overclocking, just yesterday installed a 2500k and gradually ramped it up to where it is now- 4.5ghz @ 1.3v- idle 30c- load 70c.

I've not done a massive of amount of testing yet, but it seems stable ish at the minute and temps aren't bad considering it's in a mini ITX build and I haven't perfected the cooling set up yet.

Couple of questions, the OC seems to be permanent, is there an option or any benefit to have it only OC when it's needed, kind of boost OC only? or am I ok to leave it as is?

Are the volts ok for 4.5ghz or should I look at winding it all down a bit for reliability?

Any other settings worth checking? I've only altered ratio and volts.

Cheers.
 
You should be looking for around 1.38v as a maximum on a 2500k.

Temperatures are fine for 4.5ghz but run a few benchmark tests just too see what you max out at.

2500k will only run at 4.5ghz under load; any other times it will run at a lower clock speed.
 
I wouldn't bother with benchmarks and sitting there waiting to see what happens give it a prime run for about20- 30 mins then just do some real life testing play some games do some work related things(if that's what u use it for) just use it for what u built it for there is no point in my mind to have it stress tested for 100 hundred days and so on I it works in what u use it for its stable in your situation in my mind that's all that matters,others will disagree of course so u have to do it the way u feel is right.


If temps are good upto 1.4v on air but realistically after 4.5 u won't see much benefit in real world situations.
The c states in the bios are your power saving features(down clocks your CPU when idle) make sure these are on they should be by default I believe.
Check your power settings if it's on high performance it won't downclock put it onto balanced in your power plan in windows and it will allow the CPU to downclock.

Those temps and volts are fine.
Are those temps at benchmarks or when your playing games/work? Obviously stress testers will make It run hotter than real life situations.

Actually did u use offset voltage or fixed voltage?

Tests were at benchmark, but you can scratch those original temps because I've just altered the fan set up and it's now around 60/61c during prime 95 run.

Not sure about voltage, I don't see any options other than just CPU Vcore, looking at CPUID it doesn't drop at all so I'm guessing it's fixed, and yes I've just noticed that it clocks down without load so that is cool.

Will the voltage being fixed hurt anything?
 
When the CPU clocks down is the voltage staying the same?
Some people prefer to run with fixed voltage it can/is more stable for Overclock's (mine isn't fixed)

The only thing I can see happening with higher voltage is higher temps at idle and possible degree action of the chip a little more due to the constant voltage going through but tbh the kind of degradation where talking here will have no impCt on the chip in its useable life cycle I would imagine.

Yes it's fixed then as it stays same when CPU clocks down.

Since I've altered the fan set up idle is around 26/27c. I'm really impressed with this Zalman cooler, I don't see much mention of them with the almost default suggestion of the Corsair stuff but this thing is silent and cools like a boss.
