Overclocking i5 2500k cpu

[kestrel79]

The time has finally come to try overclocking my i5 2500k for the first time. I've been running it at stock speeds and stock cooling for over 5 years on an Asus p8p67 motherboard.

 

My new Noctua NH-D15s cpu cooler arrived today so tomorrow night think I'm going to clean everything, install the new heatsink and fan, and start her up. If all is good I'll start overclocking.

 

I know many of you overclock here and probably have on this very cpu before so any tips, guides, or videos to follow along to would be greatly appreciated thanks!

I got my at 4,7 Ghz but i did sell it not so long time ago. I have to check if i have left some data on mobo settings.

I was able to achieve 4.5GHz without touching anything other than the multiplier - I personally find this to be the most "favorable" type of overclock... The type where you get free MHz without having to tweak a bunch of other settings.

I am running mine at 4223 MHz with a multiplikator of 41.

Running mine at 4.5 with only multiplier adjustment.

Here's a video that overclocks a 2500k on pretty much my exact motherboard. Do these settings all look pretty safe to adjust?

 

Think I was going to just start out around 4.0, see where I'm at temp wise and then try 4.2, then hopefully 4.5

Before I upgraded to a 6700K + Z170 Pro motherboard I was running a 2500K + P8P67 Workstation Revolution motherboard (ie. very similar build to what you have now) - I didn't need to tweak anything other than the multiplier to push up to 4.5GHz and with an H100 I generally didn't see temps above 55C.

Thanks Ghost,

 

The easier the better for me. I'd rather not mess with all the settings like in that video or voltages stuff like that.

 

I do have CPU-Z downloaded and Prime95, stuff to monitor temps. I'll be cautious.

With a Noctua NH-D15 you will not overheat the cpu. You can easily reach 4.5Ghz.

The voltage of the core degenerates the chip more than the temperature.

The i7 3770K can run (gaming) in the 70°s safely.

What are safe voltages? I don't want to ruin my cpu, it's been so good to me over the years

I have a NH-D14.

This.  Just use the multiplier and work your way up to what is comfortable.  If you've been running at the stock 3.3ghz then you're in for a pleasant surprise.

1- Overclock by steps of +300Mhz. Over 3.9Ghz +200Mhz steps, over 4.2Ghz +100Mhz steps
2- Run Prime95 for 5 min

- Success, go to 1
- Failed, increase the Vcore by one step or decrease the frequency, go to 2

Target for less than 1.4v, less than 80° with Prime95. Run Prime95 6hrs for stability.

I use the offset mode to be able to use the step down function C1E.

Ok got my new fan installed. Much lower temps, about 20 degrees cooler running iRacing than my stock fan

 

Went into the BIOS  to try a mild overclock and I have a problem. I do not have the same options as the video tutorial people, there's no way to set the multiplayer 45, it's checked as "auto" and it's in purple so I can't edit it or change anything. Is my BIOS locked somehow and I have to put it in a manual mode to edit this stuff or do I have a motherboard that can't overclock or something? Pretty sad right now.

My i5-2500k has been overcloked to 4,8ghz, but that is on a overclocker P67 board. This set up is from the release date of the i5-2500k in my case march or april 2011 When running at high overclock settings I aways remove both side panels of the PCcase and place the whole case horizontale, as heat is always going up, nothing can block the generated heat now.

 

I have noticed during my overclocking experience on different boards that you always find spots that are heated up. You can feel that with your hand. If you have crashes considder to put in a small ventilator on that component. In the case of my mobo it was the P67 chipset that needed extra cooling. On my sons PC it was also the chipset and MOSFET were heated, after a small fan and heatsinks installation it was ready, going for the next higher level.

 

Dust, always the problem, get an spraycan that contains compressed air and a pensel used by painters. Clean on a regulair base the components.

 

Information, I think the best site for an starting overclocker is stil the overclock forum as already been publish.

 

edit. PSU, do not forget that when overclocking in my case also the Vcard, the well calculated PSU may have a problem in generating that extra needed Watt, be aware of that so do a recalculation, some free PSU calculation sites do have OC settings.

Maybe the bios menu depend on the bios version used.

as a sample from the search on overclock forum, use advance search for going deeper.

 

Why not use ASUS own overclocking software think this is very handy and do provide safe automatic adjustments for starters.

Thanks guys for the reading material! I'll go through this stuff when I have more time but right now I'm coming to you on a 4ghz overclock!

 

I got it working last night, turns out I just had to type the multiplyer number in, I thought I had to press enter and select it from a drop down menu like the other motherboard options...I was tired and frustrated it was 4am so I think I just flat out missed that. But I pulled out my motherboard manual and read that chapter and it helped.

 

I spent a good couple hours cleaning my PC case and taking fans out and cleaning them as well before installing the Noctua Heatsink and Fan so it made me a little tired when it came time to overclock. I'll try to get it a little higher next and monitor the temps with 4.5ghz being the goal.

Nice

[kestrel79]

Okay this weekend I bumped up to 4.3ghz, ran over 4 hours of prime95 no errors.

 

Max voltage during the test was 1.376v...this seems high from what I've read right? I might have to manually enter a lower number, I did nothing but adjust the multiplyer like you guys said and the voltages went up.  Temps on the cores never went above 66c. This Noctua fan is a beast, and very quiet too, fans are running at 1500rpm all the time and my case is not any louder than when I used the stock cpu fan. The Antec 900v2 case has a lot of fans too which is helping as well.

 

Only actual in game test I have run was in iRacing, I took one of the new cars out on the Nurburgring, iRacing's most demanding track performance wise. I was kinda disappointed to see my framerate not really change. I'm still around 50fps in the pits and dip down to 40fps during the really complex part of the track with lots of buildings. I thought for sure after the overclock I'd get a little bump in fps during these demanding parts of the track.

 

Maybe I'll get more performance increase with flight sims like IL2 and DCS which are more cpu based that my computer has struggled on in the past?
