Your BEST 2500k overclock on STOCK HSF!

post #1 of 5
Thread Starter 
Hey guys, just as the title says... Post your results and parameters for your best stock HSF overclock on 2500k!

I don't feel like there is enough love for the stock HSF. It's quiet, it's small, it's free. Maybe I got a good chip, or a stellar fan, but I am pretty damn impressed with mine.

Stock CPU, all stock settings on Asus P8Z68-V LX temps under Prime95 fully saturated heat:

Voltage: 1.24-1.26 (auto mobo settings)
Idle: 34c
Prime95: 68c
Ambient: 22c


After some tinkering, my best results so far:

4.0ghz

Voltage: 1.2
Idle: 34c
Prime95: 74c
Ambient: 22c



As you can see.... I have undervolted, and overclocked to 4.0ghz with very little heat increase; granted, I did have higher volts than necessary running stock on auto voltage settings. I have been running Prime95 for about 45 minutes now and temperatures are completely stable at 74c on all 4 cores while surfing the web, skyping, etc. I am just doing this for fun and am not interested in getting a 212+ (I have one in another computer, and it works great although I do find the lower end ball bearing fan to be a little "clicky" sounding and annoying).

PS: All testing done with Antec 300 case, both top and rear case fan settings on low and tucked inside a cubby hole in my computer desk. Not an ideal location for it. When I took the side panel off and let it breath outside of the desk, temp dropped by about 4c!

I don't think this is ever a good idea.

why not? seems like a fun little competition that everyone can compete in. As long as the temps are in check I dont see why it would be bad?

OP: you should make some rules and make it into a little comp like i said. maybe a 6hr prime blend test and screen shot of CPUZ and temps too biggrin.gif

should be fun tongue.gif

Why not? Like the other poster said, temps are in check and it's something everyone can try. I have a completely average set up in terms of CPU and Mobo, so the average person out there can really see what these things are capable of. It seems like people just go OVERKILL these days. It's funny to me that someone would spend $20-100++++ dollars on EXTREME MOBO, cases, fans, water cooling, case fans etc. etc. etc. to overclock a chip which will be outdated in less than a year. I'd rather save the money NOW and spend it LATER on a chip that natively runs faster than what is currently on the market and not deal with all the associated headaches of extreme overclocking. I realize I am on overclock.net, but this forum is also where the average consumer tends to end up when googling information about these amazing gaming processors. I want to give them the practical side of the coin, not just the perspective from the guy whos running liquid nitrogen cooling, know what I mean?

Personally, I ran a Core 2 Duo E6750 (stock is 2.66ghz) @ 3.2ghz from the day I got it 4.5 years ago. All I did was crank up the multiplier and run auto settings and let it rip. Tested for 12 hours in Prime95 blend and temps were right in line with the acceptable "max daily driver" temps people were suggesting at the time. I had an ABIT IP35-Pro mobo. The CPU and Mobo never let me down ONCE in all of that time. The speed was significantly better in Windows and I picked up huge frame increases (CPU bottleneck) on my 8800 GT. This is the experience I've had overclocking on stock HSF and it's been an entirely positive one. I want people to know it's possible... and afterall, we're all here to learn and push the limits right?

You don't need to explain why you're doing what you're doing, because people will still do different things. Not sure how many people will start doing this, since this is OCN, where people are more than willing to through money around (some of the time lol)

As for clocking my 2500k, I haven't even bothered to despite being on a H60.

Also people spend extra money on motherboards because generally they last longer, or have features that people want/require. You don't even need to run liquid cooling to push your CPU even further anyway. There's a reason why the D14 is regarded as the best logical step before diving into liquid cooling. And yes, the CPU may be outdated in a year, but does that mean it's performance is bad? No. It just means that it hasn't got some features of the newest processors. Coolers can also be used for a lot of system, provided you find the right bracket for it. They're reusable so it really doesn't matter if you get something new.

I don't want to use this example, but Bulldozer came out and people were unamazed with it's new-ness and put a ton of proverbial crap on it. Newest doesn't always mean best - plenty of people are still using SB here instead of going to Ivy since an minor upgrade doesn't really justify it. Buying a new system however, is a completely different story.
