overclocking i5 2500k

[m_ani3]

Hey guys need help oc'ing my 2500k

currently have it at

4.74 with 1.33 volts.. tried selecting 1.4 in my bios but it just keeps crashing.. tried it thru control centre .. same result..

my aim is to reach 5ghz.. hence why i tried changing the voltage first...

my loop for cooling consists of the ek hf240 kit with an xspc rx 240 rad as well ..

You are going to need more than 1.33v for 4.74 try ~1.38v you may even need 1.40+ also depending on how good your chip is.

Forgot to ask what BIOS settings you are using?

Please post your other BIOS settings. 1.33 Volts Vcore seems pretty low, but anyways : What board are you using? Have you updated to the latest BIOS because newer versions generally improve stability.

not sure of what settings you mean.. but this is what i set in the bios..

it does seem like i have a pretty decent chip.. it passed 24 hr prime as well

i hunted a particular batch that have been reall good clockers at low voltage..(batch number..3048A683)

on the left ull see current cpu voltage .. that i have set in bios..

i have a msi gd55 at 1.7 version now...

You have definietly got a good chip to do 4.7ghz @ 1.33v I can't even get mine stable at 1.38v, that's probably more to do with my motherboard only being the standard P8P67. BIOS settings are ok, no point in changing them if you have a stable overclock i was just wondering if you have LLC on ultra high and Duty and Phase control on extreme because they help with stability.

I think i'm going to track down a 2500k from that batch, where did you get yours from?

i have the pll voltage thingy enabled i got it from pccasegear.com( in Australia)

but yea look out for the batch.. it is a sweet chip ... with the right mobo you can get really good clocks.. in the ocau forums the asus boards do look like they have some juice...

I couldn't get 5GHz stable without upping my voltage to 1.44v. So I'm sure you're going to have to up yours a decent amount.
