this is with llc at 2
llc 1 has voltage go up to 1.33

Ive tried going to 4400-4500 a few times, playing with some voltages, but never got it stable even at 4400 (using the pre-set 4.4 Turbo mode also isnt stable)

this mobo is pretty budget, not the best for overclocking, is that why I cant OC more ?

or was I doing something wrong ?


Can someone with Z77 Pro 3 or similar give me a rough idea/approximate of what voltage settings/values I should set (or at least start with) to get 3770K to 24/7 stable at 4500 or 4400 ?

Much obliged



edit: from reading this thread it looks like I could start with:
- off-set of +0.005
- Turbo Voltage +0.050 or so (maybe higher) if Im going for 4.5 GHz

not sure what my LLC level should be set to .. 3 ? Any other settings to change ?




try if your cooling is water and quality using turbo volts of +0.090 to get 4.7. 4.5 maybe +0.080 and wind it back till you fail prime?
leave llc at 2 (1 worked well for me too)

if you give all your bios settings I bet I can help you dude

Hi Guys,


Major thanks for the guide, it has worked smoothly so far

However, I am running into an issue pushing past 4.4ghz

System

i5 3570k

2x 4gb g skill ares 1600 RAM 1.5V

When I try to push to 4.5gz, I get the BSOD 0x50

I've tried increasing VTT to 1.1 (previously it was set to automatic and showed something like 1.068)

I still get the same BSOD 0x50

Should I increase my ram voltage to 1.55V? Is this safe? Or do I need to keep increasing VTT? I can't seem to find much information on VTT.


Thanks!

The setup (what matters)

Core i7-3770 and Asrock Z77 Pro-4.

Background:

I own a Core i7-3770 (non-K version) with maximum turbo boost of 4.3GHz (actually 4.3/4.3/4.2/4.1) with a Z77 motherboard.

When setting the multiplier to 43, the maximum temperatures when running Prime95 and IBT wasn't making me happy, sometimes would go as high as 90°C, so I decided to make a manual fine tuning in LLC and base/additional turbo boost voltage.

The first thing I had to do is to find the lowest stable VID with turbo boost disabled (base clock of 3.4 GHz), then after find how many additional voltage I have to add to the base VID to make the CPU stable when the maximum turbo boost kicks in.

I managed to find a base VID of 0.880v (24h of Prime95 blend and 50 IBT passes@maximum stable), this makes happy because the maximum temperature was 58°C during the tests, then I were about to proceed to enable turbo boost, bump additional turbo boost voltage and run a new batch of tests, but something caught my attention.

Using HWINFO and AIDA64 to log data from sensors, I noticed that the TDP remained the same (about 58W) no matter how low the VID was, this means that the electric current would just go up as I reduced the VID to keep the TDP the same. What I mean is:

Stock 3.4GHz VID @ 1.220
58W = i * 1.220V, so i = 47.54A

Undervolted 3.4GHz VID @ 0.880V
58W = i * 0.880V, so i = 64.91A

The questions:

The abnormal increase of current is going to stress or damage my CPU and motherboard VRM running this undervolt 24/7?

I am missing something and the sensors are inaccurate, or my assumption that the current is being bumped up to compensate the lower voltages is right?

risingstars-

0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x


leave your vtt at auto

I have clocked my 3570k three deifferent ways now.
offset, fixed, and turbo voltage and only ever had to change my ram volts to 1.65-1.70 depending...
llc I find is best at 2 or in some cases 1.

run stock cpu and just oc your ram to see what volts it needs at what settings

oh and don't care what anyone says... I disable all c states in all circumstances

Question!

I'm a little confused about safe VCORE and VID ratings for the 2500k.

I've just started OCing my one on a asrock z68 extreme 3 gen 3 that I've had for ages. I have it OC'd to 4.5GHZ with a CM neptulon 240m with prime 95 running and i'm getting temps in the mid 50s at the moment so thats good.

in core temp it's saying that my VID is 1.4312v and CPU-Z says that my vcore in fluctuating between 1.296v and 1.312 volts.

I know it should be under 1.4V for safe 24/7 use but I dunno which rating I should be using!

I have the CPU in offset mode in the bios and the offset is on the lowest one as the guide says at the start.

Are those voltages safe? if I want to go for 4.6 or 4.7 should I leave as is or set to fixed voltage? Not worried about electricity as much as not killing my cpu.
post #9147 of 9168
Using the offset mode, I have managed to get 4.6Ghz with +0.005v offset and +0.004v boost stable for 6 hours of P95. I am having issues getting it to boot at higher clocks, should I be increasing the boost or offset voltage? What is the maximum offset voltage you guys would adopt?

Cheers
My First.

Ive used both

atm I have boost at +04 and offset at +105 (if you switch them much the same. try it so you can see)
pll overvoltage enabled and running 4.7 with ram at 2400 also

llc is at 2

I assume you mean boost at +0.04? and offset at +0.105? This sounds dumb I always thought the offset was applied to each multiplier (46*0.005) but is it actually just a fixed amount?

yeah that's what I mean.

offset is a voltage adjustment the same as boost volt. you can also change offset to fixed and do it that way
