Can't hit 4.4GHz i5-3570K

post #1 of 7
Thread Starter 
Hello! I run 100% stable at 4.3GHz. Prime 95 for 72 hours with temps no higher than 65C and Intel Lin Test for 10 passes at no higher than 67C. I have a Hyper 212 Plus with 2 fans in a push pull configuration. Once I up the multiplier to 44, I become completely unstable. Normally, I would up the voltage, but I have a Z77-DS3H mobo, so that is out of the question. Thanks!

get a udh5 or something i managed 4,5ghz @ 1,35v on my formula z77

What vcore is that at?

I get that that is an option, but I have OS X running perfectly at this point smile.gif And I am cheap.

This board only supports auto voltages. If I up the base clock, would that gain me anything?

You can check the Vcore / Core Voltage / CPU Voltage through the Operating System using a program such as CPU-Z / HWInfo64 / HWMonitor64.

Upping the base clock can gain very slightly higher clock frequencies but, it can decrease stability of your system in overall.

In my experiments, there was no chance to have it running stable with less voltage than it needs for a certain speed by using the base clock over the multiplier. What I mean is, if it does need a specific Vcore voltage to run a 44 multiplier at 100MHz base stable, it will need the same voltage to run a 43 multiplier at 102.3MHz (that also ends up being 4400MHz).

You should try it as it might behave differently for you with your Auto voltage stuff, but those 102MHz base clock also play a role for the connection to the graphics card and connection to the PCH or something, and it might give you problems over there.
