voltage

[kilobravo]

hi guys.have a bootable 4.2ghz on i7 950.but not stable in prime95.after 10 secs it reboots.core voltage in cpu-z 1.248v,but i have 1.48v settings in bios,whats going on here.really dont want too much voltage.

do you have LLC enabled and speedstep turned off

 

[kilobravo]

yes have followed one of Toms advice too another newbie

 

[thestepster]

give it another bump up on the voltage one step and try it but u should be fine till 1.35v dependant on your cooler

 

[kilobravo]

thank you thestepster.have 1.52v in bios now,but cpu-z is reading 1.248.

its a puzzle,why the volts in cpu-z wont go any higher.

 

[kilobravo]

i have a noctua nh-d14.it should manage the temps.

4 ghz oc and it didnt go any higher than 59c

 

[AMDFTW]

dude 1.52v is gna kill your CPU

if its set in the BIOS thats the voltage or atleast i have gone of that

yes i now AMDFTW,but cpu-z and bios info reads 1.248v and settings 1.52v.

its quite a difference

 

[thestepster]

yeah dont stick that much volts through ur cpu mate, if u cant get it stable @ 4.2 with all volts up to that it means ur cpu's at its limit

 

[AMDFTW]

well you have LLC enabled so no Vdroop should happen.

so trust the BIOS only it will be a problem with CPUz

download Coretemp and makesure you have the latest HWmonitor and CPUz

 

[thestepster]

temps u should rely on realtemp thats deffo the best for intel coretemps more of an amd thing and hwmonitor is bad 2

okay guys,thanks for your time,think i will give it a shoot at 4095 and lower volts.

 

[AMDFTW]

yes reltemp is good i just forgot the name

i would get the volts sorted first before i OC and tweak anymore

 

[thestepster]

and use msi afterburner for ur gpu temps and clocks

yeah mate set it back to stock and then work ur way up and see if u can get an oc on it but mate dont go over 1.35v cause u might have temp issues from there but if u dont get temp issues try it a little higher but not much mate

 

[kilobravo]

have coretemp 0.99.8 and cpu-z 1.55.

maybe ill try realtemp now.

also using msi aftb 2.0.0

coretemp had some funny readings at my crosshair IV and p2 1090t ,even at stockspeed.

 

[thestepster]

yeah i wouldnt even bother with coretemp mate stick with realtemp and afterburner for temps

 

[kilobravo]

mannn,did i make a bummer

did a mistake of vtt and corevolts.hmmm what a newbie i am!!

made a prime95 stresstest at 4.2ghz,1.304v and survived

71 67 69 66 celsius

i am very happy using noctua nh-d14

 

[thestepster]

try LinX and do a 20 pass max ram that will find out if ur stable in about 40 mins

okay ill try that out,downloading linX now.

thanks.

 

[AMDFTW]

but if it passes thats a nice clock and volts fella and temps.

you might be able to go a lil higher if it pases linX
