aha that is intel point....they have "power" to pull the string...but let them sell it well first...then they release new mobo can "SLi-ish" internal + Discrete GPU..
but i cant blame them...If I were them...also do the same move =PROFIT

btw Does Lucid Hydra apply to those thing?   hope to see some review in near future 

i already checked their website. If you compare ud3p and ud3, it only stated that ud3p has 12 phase power design but did not mention anything about ud3

Dont take the Asus LE version, not worth it, non LE only RM599 but 12 phase power vs LE is 4 phase power design.

The Asus you listed there should be same cfx speed as gigabyte since the more expensive non LE version also 16x/4x

the more phase power, the more is the stability. Phase power reduces ripples, hence better overclocking.

Wanna ask if I were to buy kinsgston value ram DDR3 1333MHz 4GB module x2 (which would give me 8GB), is it possible to OC the i5 2500K to say 4.5GHz?  Or should I get DDR3 1600MHz ram instead?  I ask cause the price difference between 1333 and 1600 is about double.

No way to overclock ram alone?  I mean besides overclocking the CPU, can I also overclock the ram as well?  Say supply more voltage to the ram etc....

So what now?Buying a ddr3 1600 hyperx is not worth it?

Sandybridge maximum safe voltages
Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!



Processor - Basically we recommend customers not to exceed 1.35v to play it safe, all our bundles are set at 1.3250v or lower, any competitors offering bundles above 4.6GHz you should be enquiring as to what voltage they are using as we believe anything over 1.38v will limit CPU lifespan and anything over 1.42v will likely kill the CPU or severely limit its lifespan.

Memory - Intel recommend 1.50v plus/minus 5% which means 1.60v is the ideal safe maximum, but we have found in our testing all 1.65v memory is fine. We have also found most new 1.65v like Corsair XMS3 will run at its rated timings with just 1.50-1.55v which is well within Intel specifications. So people upgrading to Sandybridge you can still use your old DDR3, but we do recommend you run it at 1.60v or less. We are shipping most of our bundles which feature Corsair XMS at 1.50v-1.55v at rated timings. We've also discussed with Asus and MSI regarding voltages for memory and they also confirm in their testing 1.65v caused no issues with reliability.

Base Clock - To put it simple if you value the life of your components, do not overclock using base clock!

PLL Voltage - Again do not exceed 1.9v!

guys, there are some case of dying sandy bridge due to oc which can last for few days , overclocker.co.uk has put on these oc guidance

So what now?Buying a ddr3 1600 hyperx is not worth it?

actually can anyone tell me the speed or any difference in using the core-i7 and the sandybridge core-i7 speed.

I think the result is based on highly multithreading test such as video encoding. I yearn to see performance on gaming.
BUT! That's comparing to i7-950 or 980x

if sandybridge 2600K eats 980x and 950 snack for lunch, I can only pray for Bulldozer if there is any miracle.

Nope.
Unless you're a hardcore benchmarker... really, 1333mhz modules are more than fast enough.

Theres a really nice deal on Viewnet now where Mushkin Silverline 8GB (2x4GB) 1333mhz CL9 for only RM390+.
