2500k voltage

[Jeff_s510]

SO guys, im new to this forum, but have been reading it for years now, and i have a question im really confused about with my 2500K when i OC it. i can get it to 4.5 no real problems, except in CPUZ it shows my voltage at 1.4+ and that hops all over the place. in my bios i have the voltage set to 1.31 with a steping of 5

Can anyone explain y the numbers are different in this way?

 

[Jeff_s510]

i realy cant get any higher than 4.5 and be at all stable.

It sounds like you've got VDroop (or it's equivalent) set to it's highest state. Where the motherboard will decide what voltage is required to keep the CPU operating.

Can you give any more information about what you've done to obtain your 4.5 Ghz overclock please.

You can go down the instant boost path where you select a profile and let the motherboard set everything as it see's fit to hit your target but you're not really optimising your system for best speed/temps.

im not sure if theres an easy way for me to link here my exact bios settings is there? if so i can do that for you

its a gigabyte Z68X-UD3 board

you need to use multi steps load line. The trick is to start at maybe level 6 or so go into windows run under load and see if idle and load voltages are similar. If it goes much higher than idle then lower the LL level, if it goes much lower then raise it. Eventually you want your load and idle to be the same or at least very close. e.g my 4.3 ghz overclock is 1.33 idle and 1.32 load with multi steps load line level 4 and 1.32 vcore setting in the bios. Once you have found your correct level all you need to worry about is altering the voltage to get stable

hope this helps

thank you, best explination yet lol. now i know what i will be doing today yay.......

trick is mate to set vcore to 1.35v in bios and then change the llc so when you load the cpu in windows you get the same voltage as you set.

that way you are in control and know you get what you will get as(/if) you go higher.

but should i worrie about the idle voltage? or just the load voltage?

 

[Jeff_s510]

no mater what i do, i seem to get about a .05 - .08 drop under load....so when i set it for a final load voltage to get 1.35 my idle voltage is around 1.42 - 1.43 and that from what im reading i should be worried about....

 

[marsey99]

llc only kicks in when loaded mate.

edit

that doesnt sound right, llc should increase the volts a little under load not drop.

 

[Jeff_s510]

the LLC, thats the multi-steps Load-line correct?

 

[marsey99]

load line correction yes :/

 

[Jeff_s510]

when i turn the multi-steps load-line up, it seems to me to just jump up my voltage......quite a bit i have voltage set to 1.30 right now, MSLL set to 6 and an idle voltage of 1.49 - 1.5 and drops to 1.40 - 1.42 under load

 

[marsey99]

yea thats too high man.

i have to say i dont know your bios that well as my gigabyte z68 has a very limited one and my msi is totaly different.

there is a couple of good guides on overclock.net for that series of gb boards but atm my google skills seem to be weak as i cant find it. i know 1 of the guys from it did a youtube vid too which might help but i cant find that either

iPhail atm

haha your "phail" is still better than im doing right now so i say ur doing fine....im still a little new to the more extreme side of overclocking, and trying to learn some things can be a lil wierd when most guides r writen for asus boards......and everything seems to be labled different on the gigabyte boards....at least to me they seem to be

 

[Jeff_s510]

ive just been fustrated with it latly, not being able to get over 4.5 ghz stable...4.5 works great, low temps, has never locked up on me, load voltage around 1.32.....temps at or just under 60C full load, but i got 4.6 and i cannot get it stable at all, 4.7 just dies, and will not boot at 4.8

 

[WillSK]

trust me i had the exact same problem as you.

Firstly turn off all power saving options C1 C3 etc. and overclock your core clock and not just turbos (you may be doing this already i don't know Obv don't touch the BLCK)

this way when you go into windows you should be at your overclock

on idle you want it to be very close to what you set it in the bios and uder load you want it to be what you set in the bios if that makes sense. the smaller the jump the better like my 1.33 idle to 1.32 load (i am set to 1.32 vcore)

make sense??

ya i have all the turbo disabled, just the core clock of 4.5 full time, but stupid noob question maybe, what is the c1 and c3

 

[simsimma4]

C1 and C3 is intels power saving modes, basically puts cores to sleep when idle to conserve power
