so the old rig went to my brother and he did a little upgrade and wants to push the 24/7 OC to a higher level.

spec:
3570k
ga-z77-d3h
8gb 2400 c10 ram
h100i
4.4ghz set by x44 turbo boost, high llc, vcore voltage response fast, pll 1.650v
all other setting standard or auto. vcore is showing as 1.248v in hardware monitor.

the temps are 22*c - 54*c
the dvid seems to be greyd out in the bios.

when the system was mine it had an air cooler and ran hotter than that. i wasn't able to run 4.5ghz without the odd crash from time to time. upping the voltage created too much heat.
as it ran stable with just a few settings changed i left it at that and didn't try to get it cooler or faster.

what would be the best way to start to up the speed, is it possible to keep using just the boost multiplier?
this really helps it clock down when on light duties.

thanks for reading
 
just set all turbo ratio's on auto and set a 45x cpu multi

you using fixed or dvid/offset cpu voltage?

for 4.5ghz try normal cpu v and high loadline calibration and +0.10v dvid

if too high a load cpu v then try medium llc,if not enough stay on high llc and use more dvid so try +0.015v +0.020v and so on while keeping an eye on your load cpu voltage while stressing

also set vcore voltage response to fast and pwm phase control to extreme performance
 
the vcore is set to auto for now and the dvid setting is greyed out. will check if it comes back active if the vcore is set to a manual setting. cheap mobo.

will setting the cpu multiplier higher mean the eco functions won't down clock the cpu when just web browsing?
 
hmm a bit weird. so if the vcore setting is set to 'normal' then dvid is adjustable, if set to anything else then dvid is not adjustable.

took some screen shots of bios.
cpu z says i'm running 1.6-3.8ghz now? moving around as it clocks up and down
core temp says 3701 or 3801mhz
hw monitor says min vcore 0.948, max 1.152

how come it's not clocking as high using the cpu multiplier compared to the turboboost?
do these results mean i need more dvid added? (bios defaulted was +0.055v)

ok so upped the dvid to +.020v and moved the boost up to x45 and it seems stable and cool at that setting so far.
vcore only went up to 1.224v
no whea errors.
max temp 54*c

would it be better to just turn off the boost funtion and just use the eco setting and dvid to down clock off high load?

only testing with prime95 for now, was reading that it's not ideal anymore and there was a better tool. can't remember what it was though, any surgestions?
not bothere with intel burn in test either.
 
yeah on gigabyte vcore has to be set to normal to allow dvid use.

can turn the boost off and just leave the overclock.

8pack's usual recommendation for testing is to use the system for what you normally use it for and not to bother with things like prime.
 
if turning off the boost (it's not doing anything anyway) will it still clock down if i leave the eco setting on auto, like c1e and eist?

so does that mean with the gigabyte board it needs much more dvid to get the OC stable?
 
yeah if the speedstep settings aren't disabled it will still down clock it.

not that i've seen, really depends on the board/processor.

i've got the rev 1.0 version of the board you have in your sig, up to 4.5 the dvid only needed upto 0.05, anything above that needs a bit more.

the default vcore on my 3770k is around 1.18, so i guess it needs the extra.
 
yeh got the rev 1.0 on the old girl aswell. will try reducing the dvid till it becomes unstable.

well maybe not, will try upping the cpu multiplier and see how far it will go.

thanks for the info.
 
ive never bothered with turbo boost clocking,just left it on auto and clocked through the cpu multti

it will downclock still,just balance the llc amount and dvid amount to get the required load cpu voltage
 
been playing with it for a couple of evenings and it runs hotter with cpu multipler than with boost. only by about 5*c, also on cpu is uses more watts.

it's still over volting at the moment so once i get it down it may be cooler and use less power. it is needing a lot of dvid to get the volts up even with llc at extreme. tried just using static setting for the cpu with no dvid and it was much more stable but even warmer and more power hungry, though i started high (1.350v) to avoid crashes.

in the mean time i've been trying to up the clock speed too as the temps are not even touching 60*c yet. would like to get to 4.8 if possible. 4.6 is stable so far but need to fine tune the overclock.
 
what have you got for imc/vtt voltages, think they show as around 0.925 ish on the board, 1.05 should be ok for both, i know one of them can take 1.1 but i can't remember which one.

pll voltage, have you tried lowering it to see if it will take less than 1.65 ?

4.8ghz might need a lot of voltage..

yeah my 3770k needs 1.35 for 4.7, but it needs 1.4 for 4.8 :(

I don't touch those if running just 8gb

with 16gb of ram I have to set cpu/vtt to 1.10-1.15v

if just running 8gb of ram,both of those will be fine on auto
 
ok little update from the mornings testing. up to 4.8ghz now and running prime without faults for well over half hour before changing anything.

put the vcore on auto and adjusted the dvid instead, to try and get it to clock down when not at full load. the dvid is set to .130v for the min and that is reporting back as vcore 1.344v in hardware monitor.

put the pll back to auto for a min just to test higher speeds. will try playing with that again once i know it's stable. or am i making a mistake in leaving this on auto and should try keeping it at the lower setting.
max temps are hitting 65*c so no issue there.

feeling it will do 4.9 at this point. will try in a little while.
all and any advice is welcome as although i've oc's a few systems i'm nowhere near an expert in these things. thanks for the help so far!

cpu vtt is showing as 1.068v, can't see imc (is there another name for it?)
is this not a good voltage then?

from what wazza said it should be fine so no worries.

wouldn't put the vcore on auto as it could throw more volts at it than might be healthy.

the "best" pll setting can vary from what i've seen, so set it manually to the default and see what you can get out of the chip, if you have issues try adjusting the pll back towards the lower value you had earlier and see if that helps.
 
ok so tried it at 4.9ghz and had all sorts of crashes and lockups. for a 24/7 OC it doesn't seem like a good speed, so will now focus on optimising 4.8.

put the pll back to 1.650v for the min,
the vcore (gigabyte mobo) is set to "normal" (auto was a typo, ment normal) and the dvid is now 0.125v and lowering by .005v after every test.

so far so good at 4.8, just trying to find the lower limit of the volts now.

at 4.9 it crashed loading windows, crashed in the bios even. so upped the dvid to 0.160v and it still bosd within a few mins of booting. seems like too much hassle to try and force it higher. however the pll was still on auto as are many other settings. any tips to try and make it work?
is the only way it's possible, to set a manual vcore voltage? (means no dvid value can be set manually on gigabyte mobos)
 
it would be the most obvious way, as i'm not sure what the safe dvid limit is, otherwise you could up the dvid as another option.

when your using dvid, what are you seeing as the max vcore under load ?

what do you currently have llc set to ?
