Overclocking i5 2500k

[jimbop]

Best to use BIOS rather than the windows application since this often sets voltages higher than they need to be (more power, less lifespan). Try here for a good starting guide.

Most important settings are the core frequency (clock), multiplier and Vcore voltage. For the 2600k which is a very similar chip I started out by just increasing the clock to 45 (i.e. 4.5 with the multiplier left at stock 100x) and increasing the Vcore to 1.39. You can then increase the multiplier if you want and gradually decrease the Vcore until you are unstable.

Make sure you do some stress tests using prime95 or similar and keep an eye on your temperatures using CPUID HWMonitor or the mboard app. Also, note that the voltages specified in BIOS are often lower than appear in windows (e.g. in CPUID CPU-Z) due to vdroop. The value reported in windows is the 'real' one since this is the loaded voltage.

okay I overclocked using bios but under system it still says 3.3ghz, only in bios can I see, 4200 mhz turbo and 1600mhz memory, is this right? does it only overclock the turbo?

Hello, is if you well understand the Spanish, but you always have the option to use the translator you can suggest one page WEB where all are great overclockers and the community of ASUS, that if you always help if you have machine ASUS IE as your case is an ASUS MOTHER... really recommend it if you help make OVERCLOCKING in less than 4 or 5 days, also could help you I, but it is that my English is very bad and the translator not be if it could help you much... I be overclock very well...
in fact now I have my I7 950 working 4. 00GHz but as you say no is all English is using the traductor.los feel.


Try to do a post on this page that you stop you the link and tell them that you are talking and sure ANGLO which the moderator will help you know English...


Here the link to the website of ASUSXperts

I hope that you help...

Go to a proper hardware and tech site were you wont get bad advice, this forum imo is horrible for that.
