As mentioned to you that changing the radiator wont make a difference since the third fan is blocked. Any additional decrease in temperature would be temporary until the loop hits equilibrium. You may see 1-3C decrease, that's hardly enough to make or break anything.

Changing the pump may make a bigger difference in the current system as owik pointed out. Again, it's not going to make or break anything.

Adding a Rad and more fans will help you keep the delta smaller but you would require a better pump. Do note that "adding a rad" is not the same as "changing the top rad from EX240 to RX360 and have the third fan blocked". At the end of the day, though, the real difference is the delta. If your chip can't hit 5ghz, no RM10,000 worth of WC equipments can help you in that. LN2 would, but it's not a practical solution for consumers to use their pc 24/7.

can someone teach me how to overclock my CPU
can teach me step by step ?
thank you !

Then you should let us know what's your PC specs.
ohh there are some OC guides in the post #1 so you should go through it.

i gone through all it.. but still dont understand

CPU: Intel Core i5 2500k
MOBO: ASUS P8Z68-V LX
COOLER: V6GT with TX-2 Thermal Compound
RAM: 8 GB Kingston (4GBx2)
GPU: Palit GTX 550 Ti (1024MB GDDR5)
STORAGE: Western Digital 500GB Black
OPTICAL DRIVE: Samsung DVD
PSU: eXtreme Power Plus 550W Cooler Master
CASE: CM Strom Enforcer

4.6ghz is probably the best your cooler can do. Your PSU is really bad btw. Most info can be found online. If you just want a cheat sheet, this should work for you. The V-LX bios should be quite similar to the M.

im using almost the same spec as him, but my PSU is gigabyte powerock 500w, now im using 4.0ghz, but my vcore still set it as auto.

Good for you. Apparently vcore is really depends on the chip. Every CPU has different VID, hence different vcore. It's up to user to try and error the vcore until you found the lowest one stable for that particular clock. I have seen a good chip could do 4.5 with just 1.2v on load. Set it manually instead of auto as you might find a lower vcore than auto set. Thus can shave off some heat.

thanks ! but before i do the tweaks, how to detect that the cpu running on stable condition ? what's are the ' symptoms ' that cpu running on unstable mode ? , can damage the cpu ? and regarding temperature, what temperature should i aware after i overclocked it ?

and yeah i liked already your page on facebook !

BSOD will happen if insufficient vcore, it wont damage the cpu if the temperature don over 90C maybe?

i see.. meaning after i overclocked my cpu then my temp is <90 consider stable right ?

ya, but not directly check the temp after adjust the multiplier, run prime95 blend test for 12/24 hours and monitor the temperature

will try what CyntrixTech recommend me the settings, and will run prime95.. will state the what's the result after done with it.. but right now, have to clean inside the rig, found out that the cooler is full of dust ... thank you so much !

no problem
im blend testing my processor at 4.5ghz now

btw, do i need to reapply thermal paste after doing few days for the stress test?

i dont think you need to re-apply.. its an one time job

okay, even after a long period also no need apply?
blend test last night with 1.350v at 4.5ghz, passed 2 hours without BSOD, then trying to test it for 12 hours
and this morning wake up, computer shut down BSOD again

if its of high quality ones i dun think u need..

i have encounter some that will dry after few years.. but those are stock tim provided by intel/amd..

using cooler master but forgot the model




my vcore in bios set at 1.355v but during stress test in CPU-z only show 1.280v
but any vcore lower than 1.355v will BSOD

its normal due to vdroop during stress test.. tats why we got LLC feature to compensate it

This post has been edited by jeff88rey: Jul 12 2012, 07:51 PM

but my LLC level set at lowest, should i increase it? once i increase my temp will go over 80c sometimes

Guys...i need help here...my 2700k need high vcore in order to make it stable when prime...i bought 2700k because thought it are the binned 2600k which can overclock pretty well..

currently i had run 12hour prime @4.5ghz/1.34vcore in BIOS..

when i try to oc 4.6ghz/1.36vcore it BSOD...

can any sifu guide me to overclock this chip..
