but wait, turboV is just for your mobo? or my x58 can use also? i've been wanting to increase my cpu speed to 3.6ghz, but im scared i'll bust my cpu.

i7 950 to 3.6 is easy .... i am using cm gx 750w and currently running at 3.7 with nice temp .... still working to across 3.8 cause I am at newbie overclocker also ~ 3.8 is a gap for me need to config a lot of thing which i am not good enough to do it

pls give me some guide which setting i need to play with especially those voltage thing thx ~

Depends on what BSOD u got.
A bump on vcore, vdimm or lower VTT might help. 1.3x VTT is sufficient for that uncore.
Might try to play with PCIE 105Mhz, IOH 1.175v etc... ahh LinX failure could be many reasons.
Run memtest to check dram error, but for R3E I just let it auto except for the 9-9-9-x

Nice try bro. U need to manually adjust vcore more than the current 1.15v, say 1.3v should be sweet for 3.8Ghz
vdimm set to 1.65v 1st, after this u might adjust lower for the most optimized one, say 1.6v.
QPI/RAM aka VTT set to 1.3x, for that uncore should be enough.

thx bro ~ try it now

Either 2:8 or 2:10 for BCLK:Ram

Let's say for 2:8 (or 1:4) default BCLK of 950 is 133Mhz
So 133:133mhzx4 is 133:533mhz effective dram freq for DDR3 is 533x2=1066mhz
U may say 133x8 ~1066mhz for 2:8
For 2:10, effective dram speed is 133x10 = 1333mhz
Hope this helps.  biggrin.gif

this info is damn clear ! i read through alot and cant understand but what u tell is very ez to understand

possible its ur ram unstable .

btw, y ur running ur ram too low but with high voltage ?
try lower the ram voltage .

and try exactly double frequency for ur uncore .

QUOTE
We had to run 1.66 volts for stable performance even at low RAM clock speeds. QPI also needed to be nudged up to 1.3 volts.


i tot intel said maintain vdimm and qpi at 1.6 and 1.3 to get stable performance ?
actually i dont really know how to oc ram and that is the only setting i can get it boot and stable (for uncore and ram oc)~

u can get it boot doesnt mean its stable .
intel said a lot of thing .
i think u better refer to 1st page and see how's d setting on owikh84 rig .
dat shud give u basic idea on the scaling of x58 platform
*
i know it is not stable ~ and the article about the voltage thing also refer to 1st page's info
i am just a newbie and will follow what the review said ~ if follow template i dont really will get the idea and that's y i keep fail n fail and ask ~
that is better learning tongue.gif

arhhh still cant make my 3.8 stable ~ refer to many template but still cant make the ram stable even i pump a lot on it .... grrrr
below is the only stable setting but the benchmark is low comparing with my 3.7 setting ~ keep failing when i try to increase the dram freq and uncore mad.gif

Something wrong with ur ram settings I can it's running single channel. Curious how do u put ur ram on ram slots?
from CPU socket slot A-B-C-D-E-F, dual channel is B+D for ur case.
btw, what a waste 1366 running dual channel when the most interesting part of this platform is its triple.
*
yea i insert it in single channel (E,F)~ because the time i bought this rig no more money for ram so only 2 stick~
actually i am also thinking to add more or just make it double channel so my oc can go on?
if it is causing the gap

Advise to do dual channel at slot B+D. Hmm what a waste running single channel on x58, it's even worse than old 775s.

ouch u hurt me so bad cry.gif
i will correct it tongue.gif
