z270 gaming k5 offset volts over clocking
« on: September 13, 2017, 04:21:52 am »
hello peps i have the gaming k5 mid range baord with these

7700k  5 ghz ht on -delided /relided ( not glued )  with liquid metal under ihs / under water block to
g skill rgb xmp 3000mhz 16gb  cl 14-14-14-34 @  over clock 3600 mhz  cl 16-17-17-38 1.4v
msi gtx 1080ti founder @ 125+ mhz core (2000mhz )
1000w cooler master psu
intel 600p  512gb pci x nvme m.e  ssd
swiftec h320 aio cooler ( 360mm rad )

just relased  thermal take view 71 full temperd glass case  ;D :D

on to my issue  im stable 5 ghz 1.368v -1.375 v  ht on all cores no avx offset

i switched to  using  offset voltege  ( aka normal under cpu options )  then a offset of -0.035 v

all c staes on  ,voltge optmization on , rsr off ( i heard to turn off rsr ) ht on , turbo mode off since im 5 ghz all cores

issue :  idol cpu im .700v .800mhz cpu speed ,  full 100% prime 95 load   it will jump around from 1.368v - 1.41 ish  but more 1.38v  ish   and  games like bf1 ,bf4  near 100% cpu ussage sit around 1.368- 1.39 v 

is it normal for the volts to be sloppy like that on offset ? i mean im ok with 1.41 v  my temps are very good  bf1 5 ghz 100% cpu all day after 6 hrs only hits 54 c - 66c 

im ok with temps just wonderign if i can make the volts not be so funky and be more 1.368v then up to 1.41 ? 

currently  no bsods im stable  justa side note

Hello,

How does this result compare with default settings when everything is on AUTO?
If the Vcore is the same it means the offset option is not working (DVID).

For the BIOS options the CPU Vcore needs to be set to AUTO
Dynamic Vcore (DVID) = your offset value

If different, then perhaps your -0.035v needs to be lower? -0.040v?
Also adjust the Load line calibration options (if you haven't), with DVID you don't require it to be as much / disable it.

ok im scared to try auto ( i bet it will try to push 1.5v lol ) ill try

as for the cpu vcore settings

auto -doesnt let me type and offset in
normal - ( normal lets me adjust my offset  dvid )
manual  ( i have to type a manual vcore in )

thats it for vcore

i have figured it out  the offsets voltge oc

loadline calibration = auto,normal,high,turbo

load line calibration has this affect on offset voltge with oc

load line calibration=normal   - higher then selected vcore on low loads - mega vdrop on high loads (can cause bsods on 4.8 ghz + oc  5 ghz in my istance this is not working well
i select say -0.030v  ( i need 1.368 v to be stable it  will give me 1.402 v on low loads and a mega drop to 1.3 - 1.32v on high loads  =bsod  turn off set higher im 1.44v low loads and 1.34v on high loads ok  lets try high next .

load line calibration= high -pretty close to your chosen offfset volts on low load - more then selected offset on high loads

0.030 offset   low loads like 60% cpu and under im  1.356 -1.38v  wich is ok  but under  heavy  loads like say bf1  unlocked fps cap on a 1080ti  cpu hits 100% ussage tofeed the 1080ti with 144fps  anb  hits  1.405v 
pprime 95  26.6   sits around 1.368v -1.412 v  ( 1.412v is the max peak for a slight second ) 

loadline calibration=ultra     more lower then selected  offset under light loads 1.35v  and super mega jump up to 1.44v under heavy loads

thing is i found that meduim aka  high load line calibration is the best one  it doesnt bsod on lower loads or bsod on higher loads even though its feed a little more then i want

is there a way to select what vcore it goes up to  besides manual vcore ?

is there a secret vcore setting im missing  ?  i hit page up and page down and see auto,manual,normal - lets u dvid

Hmm, something doesn't seem right.

When you use the offset mode it should maintain a Vcore voltage without dropping.
0.7v, then scales up to whatever your max load SVID is.

So for example if you stopped the overclocking and run all to default settings,
- Set the CPU ratio to x45
- Vcore = normal
- Offset (DVID) = +0.010v <to give you an idea of what the default values are
- Everything else auto.

Place the CPU under a load, the vcore should go from 0.7v to highest value without dropping, hits a higher limit and remains. <Does it do this?
