Gigabyte G1 Sniper M3 Overclock with Turbo boost?

post #1 of 5
Thread Starter 
Hey all,

I've currently got my i5-3570k stable @ 4.4GHz with good temps on a G1 Sniper M3 board, but I would like to know if I can set it so that this clock rate (and required voltage) only kicks in when necessary? Ideally I'd like the machine to run in low power/low frequency when I'm just doing menial tasks like folder management and web browsing, but then when I do anything cpu intensive like video encoding or gaming the required voltage and max frequency of 4.4GHz is used if needed. Can anyone more familiar with this board or overclocking in general give me some help? Here are my current BIOS settings:

BIOS Version - F6

Frequency Settings:

CPU Clock Ratio - 44
Turbo Boost - Disabled
C1E - Disabled
C3/C6 - Disabled
CPU Thermal Monitor - Disabled
CPU EIST - Disabled

Voltage Settings:

LLC - High
Vcore - 1.250V
VTT - 1.075V
PLL 1.710V

Thanks!

Mike

enable EIST wink.gif

if you want then you can also use offset so the voltage drops under idle conditions, but you will need to tinker a bit. To use offset set vcore to normal(type it in or press +/- buttons or pageup/pagedown) and then you can set a +0.08-0.105v or something(it will add this to your VID at 4.4ghz, which I have no idea what it is so you have to tinker with the + vcore setting.

Thank you very much for the reply.

So just to confirm, I only enable EIST and not Turbo Boost or any of the CStates?

Also, when tinkering wit the + vcore setting, how will I know once I have it set so that it doesn't go above 1.25V? Can I see this in CPU-Z?

Lastly, do I leave LLC, VTT and PLL as I have them set now?

Thanks again.

You can enable turbo boost too, but you might not need too. You can also enable C1E and C3/C6 but I think all you need is EIST.

Yes you can see it in CPUz.

You can set them on auto, some people lower CPU PLL slightly, but I wouldn't bother at only 44x.

Ok, so I believe I'm moving in the right direction now smile.gif

On my first attempt using your suggestions, the core speed in CPUz dropped to 1.6GHz about a minute after startup. It was 4.4 when I first booted. When I fired up prime95, it jumped back to 4.4GHz. However, the Core Voltage shows 1.068 and doesn't change regardless of what the core speed is. Not sure why it's even showing that number to begin with since nothing in the BIOS is set to that number. I'm not entirely sure how to determine when I have the correct DVID setting either or what number to look for. I'm guessing it's 1.25V since that's the number I used before to be stable at 4.4GHz, but as I said not sure how I can determine that since the number isn't changing.

Here are my updated BIOS settings:

BIOS Version - F6

Frequency Settings:

CPU Clock Ratio = 44
Turbo Boost = Disabled
C1E = Disabled
C3/C6 = Disabled
CPU Thermal Monitor = Disabled
CPU EIST = Enabled

Voltage Settings:

LLC = High
CPU Vcore = Normal
Dynamic Vcore = +0.100V
VTT = Auto
PLL = Auto

Also, in the BIOS itself it shows the CPU Frequency as 4405.25MHz with the decimal number changing slightly every few seconds. It also shows a Vcore of 1.248 which will jump to 1.260 or 1.272 every 10 seconds or so. Not sure if these numbers matter but thought I would include them so you would have more information as to what I'm seeing. Also, the version of CPUz I'm using is 1.60.1x64 if it makes a difference.

Thanks again.

Mike
