hi, does any1 adjust cpu pll voltage manually?

i set mine at 1.68v, core temps drop a lil bit 

default 1.8v rite? i heard drop it will lower temp when set around 1.7v, but it doesn work for me, i set it 1.7v. My bios setting just let me set 1.5v, 1.6v, 1.7v, 1.8v, cant 1.71 or 1.82.

It doesn't matter and this value can be reduced safely. I suggest you to read some Sandy Bridge overclocking guide and it's very informative

hello guys..new here

wta, is there any issue if using rams that not certified for sandy?
i mean the ocing.
cuz i found my rams wont do any good with sandy divider ( >1600 )

eg : 1600 6-8-6 , 1.5v hyperpi 32mable
1866 7-9-7 any volt wont do.. even loosing up not helping so much

btw, spec
2600k
msi P67A-GD65
gskill eco 1600 7-8-7 1.35v

anything i missed, pls enlighten me cuz im too noob in intel

try 2133 8-10-7-27 at 1.65v

i dont think it capable of doing that.. a quick try 2133 with auto timings = not bootable.

but, thanks.. i will try again my luck with the timings u stated..

pst..any eco user here?

edit:
updated with ss.
only 32m att cuz in learning process.. other stress tools will take more time.

any misc voltage should i increase in order to gain higher ram clock?
tfaw stocked at 50...but i changed to 30..should i leave at 50 or better to tightening?

sorry for these questions.. still cant find a good guides to read.

Guys, What is Default/Stock Voltage for the I7 2600K?

Found THIS for ECO.
1.24-1.26v under load.

AsRock Pro3@I7 2600K 4.0@1.2v will BSOD  when running the LinX , Temp 70~73C 

BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase vcore
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

which type of BSOD?

Erm...just Whole Window Hang then restart @@ , my MB debug Code , when in window will auto close light, is it when it BSOD will show the code agian?

BSOD code can only be seen in win.
try increase vcore to 1.3v, later when got into win slowly decrease vcore.
take note that LLC will either increase or decrease vcore during load depends on settings.
C states are related to power saving, noth to do with ur BSOD
full specs of PC would be helpful. 

This is my Spec :

Proc : I7 2600K 3.4@4.0 v1.25
CPU Cooler : Intel Stock
MB :  AsRock Pro3 P67 - Bios : 1.80
GC:    Asus DCU 460GTX 1GB
PSU :  SilverStone ST56F 560W
SC  :  Creative Titanium PCI-EX
HDD : WD Blue 640GB,Samsung F3 1TB
Ram : KVR 4GB 1333@1600 1.5v x2
The Safety Voltage for Intel Stock Cooler is?  i will change it at next month.
Where to see those code? is it while BSOD? 

The LLC need close? 

Which Cooler is best on I7 2600K ?  Corsair H50? or others suggest within rm 250    Thanks .

Found out one thing, if CPU PLL Overvolt is disabled, more vcore is needed if reduce the CPU PLL voltage.

Sandy is quite boring compare to the x58 & to my daily usage i found my 990x previously is much better than the current SB T_T

if im like u so rich ok lor.. but but but poor ppl like me cant lor..
