post #7411 of 19539
hello guys newbie here got a new system last week smile.gif I'm trying to squeeze more mhz using my stock voltage in adaptive mode.

cpu i5 4670k
mobo asrock killer
cooler - gamer storm lucifer air
psu - seasonic m2 620w
gpu r9 280x


@stock settings i ran prime95 and checked my vid using cpu-z (1.145v full load)

Now booted to bios changed the following settings.

Cpu Multiplier - 42
Cpu Cache Ratio - 38

Cpu Vcore Voltage (adaptive) - 1.140
Cpu offeset voltage - 0.001 (cant set it to auto as its add more voltage upto 1.25 in total)

Cpu Cache Voltage - 1.000
Cpu Cache offeset - 0.002 ( cant set it to auto aswell, total load is 1.026 @ hwinfo )

Cpu Input Voltage Fixed 1.8 ( when setting this to fixed value the LLC setting under this is automatically Disabled, dunooo why )

Ram - Xmp Prorfile 1866

The rest AUTO

Ran prime 95 1hour so far no bsod am i doing this right ?

Temp same with stock settings idle 30-35 load 65-70. (prime95)
aida 64 no fpu stress only 55c with fpu stress upto 90c + 0.1 voltage jump i think this is the avx thingy.


Thanks Thanks!

Its best to use manual voltage when testing,if u dont u run the risk of damaging your cpu. Read the first page of this thread!!

Do not use adaptive voltage to run tests! Read first page of this thread!

i have the same problem with auto in offset .. i think asrock still got some bugs in the bios.

If you can achived 4.2ghz 1.140v give it a try to set the voltage on manual and set the core to 4.4ghz... just leave the uncore clock and voltage as what it is now. see if you can boot to windows and run hyperpi 32mb or XTU benchmark if the cpu done the test... gor further to prime test. if bsod report back smile.gif need to up abit the voltage.... just like the guide said.. one by one. good luck.

cheers

Your VID seems a bit high.
Did you ran prime 26.6 @stock and disabled turbo in bios ?
Otherwise you will not get proper stock VID.

Nope should i do that?

I can boot to 4.4ghz using 1.5vcore but bsod at the loading screen.

My memory setting is best at its clock speed (2133) to 2600 other than is just a dead end for me dunno why, probably someone can explain.

Another thing that i don't get it well is the un-core, before i tried to put uncore/vcore 3.9ghz 1.200v (bios) and 4,6ghz 1.24v pass 3 hours XTU, 32mb hyperpi and IBT. later after i changed the CPU voltage to 1.235v and it just bsod 124 so i gave another shot upping my cache core , the result is pretty stable and i can manage the cpu voltage even lower to 1.233v (picture) hummm ......

just wondering is psu hold a big role in overclocking ? .. im using 4 years old OCZ 700watt mod-extremePro is it enough ?

cheers.

1.233 and 1.24 are practically the same voltage, you can't really make assumptions based on changing it

PSU.. yea

@jmann
Is just the right way to get proper stock VID. Good VID around 1.0 or less is indicator for low vcore CPU. But no guarantee.
For instance I have 0.995 stock VID and can do 4.5 with 1.205 Vcore.

Hey guys,

Is it really possible that my chip is this poor of an overclocker? I have an i7-4770k 331 Costa Rica batch.

While dropping ram to 1600mhz and disabling XMP, and setting uncore at 34x, no matter how much vcore I pump through it (max I tried was 1.43v) and no matter what I set my Initial input voltage to (highest I've tried was 2.15v)

It literally takes 1.37v to get 45x stable while uncore is at 34x. When I try increasing the uncore to anything past 35x, I lose stability on my overclock. Yes, I understand how the silicon lottery works very well. It's just strange that literally almost every member in this thread is hitting 45x, 46x, and sometimes even 47x+ with less than 1.3v.

Did I just get a bad chip? I'll post my settings when I get home. Using a Maximus VI Formula.

That doesn't sound too bad, just not good chip and uncore can often turbo and do stuff you don't want it to do, which is tricky for setting voltage if you don't know how it behaves (cpu-z 1.64.0 will show it, memory tab, NB frequency = uncore/cache)

You should say what kind of instability you get and with what testing. Prime28.1 24 hour will straight out cut like 200mhz from your game/encoding/everythingelse OC often
