currently using i7-4770k at 4.4ghz with 1.28v offset +0.02v
using msi-z87 g43
cant get any higher speed without crashing with intel burn test

so if i got a bad processor, what can i do?

my friend got 4.6ghz easily on 1.32v but i cant
i even jump to 1.45v, still no luck on 4.6ghz

You should know that all chips perform differently, right? Furthermore, not only the proc, but mobo, RAM etc etc all affect the ability to OC. And then there are also temperatures to take note of

Some got lucky with 1.25v @ 4.6GHz. They say there's a bell graph where small percent of the best and the bad were released into the market while most the the chips are average performer, for this Haswell and heck for every model. Now don't think that the bad chip is bad but they won't overclock well. Come to think about it, overclocking void the warranty unless you get it covered with http://www.intel.com/go/tuningplan

What cooling are you using?
as i know 47k scale well with lowering temperature... Especially during loading spikes
vcore not so sensitive, sometimes reduce will help

using seidon 120v

can you upload some of the print screen when running burn test?
esp. temperature

Haswell ocbility differ from chip to chip, sometimes d diff is small but sometimes it's huge. tested 2 chips before, 1 managed a 4.5GHz with 1.19v, another hit 4.2GHz only with almost same voltage. could be temp limitin ya mileage thou, 120v is definitely not a top notch cooler.

it jumping from constant 75-80, to sudden 99-100 dgree

looks like very high chance limited by your cooling capability

any suggestion on cpu cooler around rm150?

Overclocking Guide Part 1:

take you time to read.

tq,
after reading the motherboard manual, i've got to overclock to 4.5ghz (finally!! )
but the voltage have to configure high, so temp r quite dangerous

any suggestion on budget cpu cooler? my vcore right now is 1.38v with offset +0.02v

4770k 4.5ghz or higher sit around 8x-9x c was normal... if you have money buy @ build custom WC system.. it can help to reduce heat around 10c or less mybe

owh really?thot it should sit below 85 dgree. so my seidon 120v actly doing it works then

yap... it doing good job now not good but okie laa nama pon bujet AIO .. my 2700k ocing 5.0ghz sit around 83-87c .. using same cooler like you

wow!!! 5ghz! nice
yeah, i just worried that my seidon is faulty, because the cpu temp is high
bcos when i unbox it there are finger prints on the copper base!!!!!! daf*q! so my bad, i was lazy to go back to the store, just install it
since then i am worried the seidon might not functioning well

i think the pump on seidon not easy to break ..cause heat...

??what do u mean

AIO pump hard to died cause by heat.... even even liquid in AIO was boiler it still running....

most pump died cause by bad 2pin@ 3pin fan socket contact ..

TS if don't mind right, can spend that RM150 for SP120 or other better fans. Before this using that same cooler as u with SP120 push/pull config, can say really sastified with it.

different batch different quality, maybe you're the unlucky 1 get the bad quality batch

1 simple answer ..

how about sapphire vapor x cpu cooler?

always better to get a decent cooling system to start with xD
