Hi guys, hoping you can help me with my overclock.

Specs:

2500k
Asrock z68 extreme 7 gen 3
corsair h100
crucial ballistix tactical tracer 1866mhz

Currently I've done a stability test at 4Ghz on stock volts, right now I'm refining my 4.5Ghz OC.

I just want to go as high as I can on my current cooling.

Below is a quick prim95 run. 1.4v is set in the bios, how high can this go without damaging the chip? any and all help is appreciated ^^

Hows your extreme? My voltage options are crazy.

You setting Vcore manually or using offset?

You adjusting Vcore or using the Turbo voltage option? And what LLC settings you using?

I can't get the voltage to drop down to idle voltage if I manually set it, I have to use offset mode.

Is your board damaged? The middle heat sink on mine ( The one with '3 Way SLI' written on it )

It scratched to hell :(
 
Dunno, I've got a lot to learn :p

I've set it to fixed 1.4 but getting some Vdroop as seen in cpuz, this is with LLC 5 so I'm going to bump that up a notch or two.

Haven't touched turbo voltage, reading about what each thing does and adjusting it as I go along :D going to be a fun week :D

My board has a couple of minor scratches on the bottom heatsink and a small dent/scratch on the 3way sli bit! I do wonder what they did to score it though XD
 
My take on LLC.

When the CPU is set to adjust speeds and volts on the fly, when it goes from idle to load there will be a little voltage drop (VROOP).

I'm not entirely sure why this is, other than it does happen.

So. Say you needed 1.3v to get a CPU stable at a certain speed (with on the fly changes turned off) and you would then like to turn those on the fly changes on... when you do you will see some VDROOP. However small this voltage drop may be, it can totally be enough to under power the CPU.

When you know how much VROOP there is you can set the LLC and calibrate this.

Say the VROOP you see is 10% less, then you would up your LLC by +10% thereby gaining you the wanted voltage even after some VDROOP.



You keep raising the level until idle vcore matches load vcore

This isn't right, or I've not used it for this before, I'ld turn off on the fly changes to acieve that. :confused:

Educate me if I'm wrong tho, it is early and I do need coffee :P

Have you got your LLC set properly (in line with my post a few posts above), so your idle and load vcore are similar (if not the same)?

So I'm at 1.4 in the bios, 1.3911 VID on coretemp and 1.288 vcore on cpu-z.

I need to raise my LLC until the vcore or vid matches the bios setting??

Didn't get a chance last night, looks like it could be Thursday before I take another crack at it.
 
Those were under prime95 load, my LLC was set to auto at the time (rookie move :D)

My board only gives LLC levels and not %, levels 1-5 is it safe to assume it's just 20% jumps?
 
Good good, Not a rookie move, its just easier. :)

So the BIOS is set to 1.4V (manual) and under load you get 1.288?

So basically it shows your overclock is stable at 1.3v (give or take)..

So go into the BIOS set the Vcore to 1.3 and LLC to level 3..

That should work, if not try level 4 (and see what it does to the vcore.
 
I have the same CPU and Mobo, i OC'd mine by the auto OC on the bios, was quite hot, so changed to using that OC guide thats linked here, its a lot cooler but still would like it cooler if possible.

I will check this thread when i get in and see if i can mirror the settings and see what results i get
 
I've got a similar board, extreme 4 gen 3 and the same cpu and was looking at buying a NZXT KRAKEN X40, I can get one for about £60

Is this a good cooler for the cost and will it help with clockin my chip? im running stock cooler atm @ 4ghz

cheers
