Attempting 4.0ghz, core i5 750

post #1 of 4
Thread Starter 
So i'm using turboV and easy mode to boost up my overclock to 4.0 slowly from the auto overclock setting which was about 3.7

i got to about 3.924 and my settings were:
BCLK: 200
CPU Voltage: 1.375
IMC Voltage: 1.4
DRAM Bus Voltage: 1.6

i was running LinX and my temps got up to like, the mid 80's. thats not good, right? shouldn't i be in the 70's range? what should i try changing to fix this. I'm a noob so i'm willing to bet a whole lot of my settings aren't exactly what they should be.

Don't use auto OCing software. Do it manually in the BIOS. 80c is a bit high for an i7, wouldn't recommend it for 24/7 ocs.

yeah i would do it manually but every time i try to change anything manually bad things happen. do you think there's any bios settings that might not be ideal for overclocking that i should go in and change? my bios settings are mostly default at the moment.

The temps and IMC voltage is a bit high, good temps on LinX with 4.0ghz for an i5 750/760 is 70~75ºc.

Should you reduce the IMC voltage manually, the Intel limits is 1.40v.

Try this:

Mult: 20
Bclk: 200
Cpu Voltage: 1.375v ( depending your chip )
Dram Voltage: 1.65 (depending your memory)
IMC Voltage: 1.25 ( can increase later )
CPU PPL: 1.8
PCH: 1.05
Intel Speedstep Tech - Disabled
Intel Turbo Mode Tech - Disabled
Load-Line Calibration – Enabled
CPU Clock Skew – Auto
PCI-E Clock Skew - Auto


Sorry for my english !!!
