Need Help with i5 3570k

I'm running @ 4.6ghz 1.325v, Idle temps lowest 38 max 80

my issue is I want to use that thing where your CPU Frequency goes up when you need it then down when you idle,, on the MSI gd65 there's too much going on in the bios idk what to do or change

in the BIOS, look for SpeedStep, this should be enabled for low load idle conditions. but be
warned that great differences in voltage at vcore and then when "loaded" that drastically
can cause BSOD or lock-ups. now if you lowered your OC to a voltage with less difference
there is a less chance of issues. is there an overclock in the 1.275 area you can work
with because of the voltage difference is smaller than 1.325 (as seen in the CPUZ shot,
the LLC is controlling the voltage)

as airdeano said, i had basically the same setup in bios as you, volts etc, but gpu-z reports my blk as 98 not 100 lol.

incidentally, love the desktop, what is that?

That voltage seems a little high to me, for a 3570k at 4.6GHz. Is that the lowest you can get it stable?
Also, what stress test are you using to get the max temps?

Rainmeter, look it up download it, mess with it, have fun with it

it's not high my chip doesnt go over 1.3v even thought i set it at 1.325, and I blue screen if i set it lower

I use Prime 95, Core Temp, & cpu-z

Speedstep doesnt exist in this bios, you set it up using power saving features i think and idk how to use them

Speedstep does exist, dude.
EIST = Speedstep.
You are right on the temperature limit for Prime.
Disable EIST, Disable Turbo Boost and then see if you can get the voltages any lower.
Also, are you up to date on the GD65's drivers? Intel Management Engine, Chipset driver, etc.

We've got two different types of over-clock being discussed here:

A fixed OC and a Turbo (offset) OC.

What you have setup in BIOS is the Fixed OC. That is where you specifically define what clock the CPU runs at and how many Volts it runs at. There is no deviation from that profile. Just enabling EIST doesn't do anything because you have set the clock and voltage to manual so the mobo has no control and can't lower either.

The Turbo OC gives limited control of both voltage and core clock back to the mobo. All you do is play with two profiles:
EIST controls your idle clock. When the CPU in not loaded it drops the CPU multiplier to x16. When at load the CPU will automatically jump to Turbo essentially making the stock 3.4GHz clock irrelevant. You can alter the turbo speed - I think at default the turbo will run 2 cores at 3.8GHz.

Traditionally there is offset voltage control. Offset voltage is literally how much more power the mobo gives the CPU when it jumps to Turbo. So, if we set 0.92v for the x16 idle speed and needed 1.25v for the x45 Turbo then the offset would be 0.33v (0.92+0.33=1.25).

The problem is that these MSI boards don't have Offset voltage. We can partly get around this by leaving the vcore on auto. This lets the mobo reduce and apply volts as it deems necessary (I'm seeing a range of 0.91v-1.23v approx). Luckily the automatic voltage profile is over generous with voltage (you don't need 1.23v to run 2 cores @ 3.8) which means than we can get extra performance out of the cpu without actually needing to manually alter the vcore.

In order to do this:
1. Set your BIOS to default.
2. Enter over-clock settings.
3. Leave EIST and Vcore on Enabled/auto.
4. Make sure Intel Turbo boost and Enhanced Turbo Boost are enabled.
5. Enter CPU features at the bottom of the OC settings menu.
6. Scroll down and find the "x-core limit". Treat these as your CPU multiplier. Set them all the same.

Chances are that you will get to x42 and that will be as high as you can go. The automatic profile does have an upper limit (I'm seeing 1.226v) so you won't get as high as you will on a fixed voltage.

Hey presto you now have a CPU that idles with 1.6GHz @ 0.91v and loads to ~4.2GHz @ 1.23v. If you need anymore power then load up you fixed voltage OC.
