ok tried both and -0.005v didnt work (blue screen so tried +0.005v and im booted
cpu-z @ core voltage 0.360v
temp 34c -36c (on idle)
gonna stress test it now

grantsmith82 · 5 Sep 2011 at 00:03

ok now stress testing about 15 min in and its at about 64c and holding at 4800 (no loss in speed)
and at 1.360v on core voltage from cpu-z

looks good buddy

just validated mine on cpu-z

ok was on all night from middnight till 7am however when i came down i just had a black scrren like it was in sleep mode and wouldnt wake up ... so unsure if another issue or a crash anyway started again at 7am and till about 2pm was running fine (then had a power cut) would that be enough time or shall i leave it on a long run again?

thats plenty mate, i bet you have not changed your power settings! go to -

contol panel
power options
(choose a setting, high performance is hidden in hide additional plans)
change plan settings
turn display off (never)
put computer to sleep (never)
change advanced settings
just make sure everythingis set ot max or never etc

your prime time is very good, what are you voltages etc and clock?

under stresss test from cpu-z core voltage was 1.360
core speed 4799.9
multiplier x48

that to me is a sound oc mate, i personally wouldnt worry that it is over the 1.35v spec , but thats me, im sure you told me but what cooler are you using?

grantsmith82 · 5 Sep 2011 at 18:43

what should the Voltage be? no higher tha n 1.35??
my cooler block on the cpu is EK supreme HF full nickel.

according to intel the max voltage you should go to is 1.35v but in their tech guide it says 1.52v!

i wouldnt worry, your chip i take it is stone cold with that water block.

a combination of high temps and high volts will end up doing damage (overclocking 101

)

running the stress test it does upto 60c on normal ideal low 30s

dude those are well in the green, i currently have an h100 which idles at 36 and sits at 69 @ load!, i have just bought THIS BEAST which i hope will drop my temps further

grantsmith82 · 7 Sep 2011 at 19:56

that kit looks good. have to let me know the results.
i thought all was running well and good after successful stress test however when the pc was running and sat idel in windows found i have had a few blue screen errors/crashes. for now ive put back down to x47 and CPU core offset voltage from +0.005v down to -0.010 see how that runs. do u think if i put back upto x48 im ok to put the voltage higher than +0.005v ?

Nice been looking at one of those kits myself

btw just messing around with my overclock again ... does this look safe for everyday use? Cooled using H80. Been priming for about 3 hours so far. Passed Intel Burn test on max and one core hit 76.. the rest stayed around 70.

sorry image is a little small and hard to read.

just watching a movie after dropping down to 4700 blue screen again

seems ok on stress test but just using windows, emails,movies etc it blue screens

yer thats no prob, my 5ghz is offset +0.065 which gives me 1.43/4v

I have performed an un scientific experiment with my H100, I tested it at 4.7ghz and 5ghz on setting one fan and pump speed, idle and under prime. I then tested both speeds idle and under prime on setting three.
Once my H3O kit comes I will do the same and post all my results

i have heard this before, what are you ram volts? also it might pay to up the PCH, VTT, DRAM and PLL volts one or two notches and see if that helps to Stabilize

by the way i wouldnt push it much more i dont think the H80 can handle much more

what would you put these upto?

buzzlightweight · 7 Sep 2011 at 22:50

just up them one or two notches, i have read that you can safely run VTT and PCH at 1.1v 24/7 and dram is down to your ram, what are they rated to? 1.6v? run them at 1.6 and see if that helps

grantsmith82 · 8 Sep 2011 at 12:16

will give that a go running at 4500 seems ok but 4700 or 4800 ok on stress tests but blue screen crashes on normal day to day use.
i think the ram can go upto 1.6 although advertised at 1.5v
