[Overclock - BSOD] @4.5Ghz i5 2500k. Why? Help please! Gigabyte Z68XP.

post #1 of 12
Thread Starter 
Hey all, I just upgraded my system two days ago and my system is as such:

MOBO: Gigabyte Z68XP-UD3
CPU: Intel i5 2500K
PSU: Antec TruePower TP750W
GFX: MSI N560GTX-Ti HAWK
RAM: Corsair Vengeance 8GB(4GBx2)
Cooler: CoolerMaster Hyper 212+

While waiting for my shipment to arrived, I have done so much reading about how great the Core i5 2500k is use to overclock and how easily achievable it is.

At this point I am not sure why am I not able to do so. I read so many beginners' guide and step-by-step picture guide. Yet I couldn't get the 4.5Ghz where everyone else could easily easily achieve. What's the problem?

My main references are:
The ULTIMATE Sandy Bridge OC Guide + P67A-UD7 Performance Review
Gigabyte 2500K i5 overclock guide:
How to Overclock the Gigabyte GA-P67A-UD4
and many many more.

Some of the writer have somewhat different settings but everyone is kinda suggesting 4.5Ghz as the goal to set and so I disembark for that goal and left disappointed. I am not even sure what I might have set wrong in the process anymore. Hope the pictures explain better than me.







So I followed the settings from the sandy bridge guide and clock it to 4.5 and 1.375V. The problem however comes when I run Prime95, in about 5-7mins it would give me the BSOD. I started my configuration at 4.5Ghz(100Mhz*45) with 1.330V, it almost crash as soon as I run Prime95. Then I have been steadily increase by one or two notch per time till I am reluctant to go past the 1.375V bar. It's still crashing on me now!

Anyone any idea what did I do wrong? Thank you for any help you may suggest. I am on the verge of giving up at the moment. I have been playing with it for 9hours without much sleep.

It could just be a bad batch of the i5-2500k.

I am truly hoping that's not the case. I would be pretty bad in luck if that's the case. Somehow I am hoping that it's an error or configuration mistake I made that's resulting it to not achieve 4.5ghz.

If it truly a bad batch, what setting should I turn now now? 4.4? 4.2? I must say I had such high hopes in my CPU when I first saw it.

BTW, anyone have any idea why after I overclock my CPU, it shows up as unrecognised in 3Dmark 11? When it was at stock, it managed to identify it's a i5 2500k. Strange.

You just need more vcore. My 2500K requires 1.425 V with LLC enabled in BIOS for 4.5 GHz.

I wouldn't recommend VCORE over 1.35V for a daily system. Not everyone can get a 4.5 ghz...for me anything over 4.5ghz is a crash...but then I don't feed it more than 1.35V. I m fine with 4.5 ghz as my max. Also I run my comp daily at 4.2 ghz at 1.30V. There isn't much difference between 4.0-4.5 ghz anyways its more for 'bragging' rights. Your cpu is fine...just keep it at 4.2 ghz and 1.30V and you are good to go.

Also to get higher settings you might need to deal with different timings and lots of testing... but if it worth it to you? Its all up to you ... your system ... have fun with it either way you want.

You spend 9 hours trying to do this...when you could of spent the 9 hrs enjoying your new system gaming something ... LOL... jk

try disabling real-time ratio changes in OS?

also aren't your ram sticks supposed to run at 1600MHz? try enabling x.m.p.

I got it figured from another forum. Turns out the main problem is the multi-steps config. After adjusting it I managed to get 4.8GHz with Prime 95 (10hours). I am now using 4.3Ghz at 1.330v for 24/7 daily usage.
