Intel Core 2 Duo E4300 Review and Overclocking Analysis

What settings did I use to reach 3.6Ghz with the E4300? * non-standard chilled water cooler with water at 4'C * Corsair TWIN2X2048 PC8888 memory * 400MHz FSB * 9x multiplier * 1000MHz memory * 1.65V core voltage * 2.4V memory voltage * 1.55V northbridge voltage * 1.5V southbridge voltage * 1.215V ich voltage * 4-4-4-12 memory timing But what is truly impressive is that the chip was stable at stock voltages at 3.2GHz (400x8) with the stock cooler! It was also stable at 3.42GHz with a Noctua at 1.575Vcore.

Tổng quan về overclock

A) CPU SPEED = CPU FREQ X CPU MULTI B) HTT SPEED = CPU FREQ X HT MULTI NOTE: Remember that the HT Bus (AMD systems only) is equivalent to the Bus Speed in Intel systems. Substitute the terms if using an AMD setup.The name 'HT Frequency ratio' should hint that this multiplier is the 'HT Multiplier'. C) RAM DDR2 SPEED = RAM DDR SPEED x 2 D) RAM DDR SPEED = (CPU SPEED / RAM DIVISOR ) x2 E) RAM DIVISOR = CPU MULTI / RAM DIVIDER RATIO F) RAM DIVIDER RATIO = RAM ACTUAL SPEED : CHIPSET HT BUS SPEED G) RAM ACTUAL SPEED = (DDR2 SPEED / 2) / 2 H) CHIPSET HT BUS SPEED = NOMINAL MOBO CHIPSET HT SPEED / NOMINAL HT MULTI AMD systems use a HT Link (also known as a LDT Bus) . CPU - AMD x2 6000+ CPU Freq: 200Mhz - CPU Multiplier: x15 CPU Speed: 3000Mhz Motherboard - M2N32SLI - Chipset HT Bus Speed: 1000Mhz - HT Multiplier: x5 RAM - DDR2-800 - DDR2 speed: 800Mhz Intel CPU Clock Speed = Multiplier x FSB (also known as Bus Speed) DDR RAM Clock Speed (on 1:1 ratio) = 2 x FSB (also known as...

Stronger do ca sĩ Inez

Once again I'm longing For your hungry touch Picturing you on me I am missing you so much You turn on my imagination Though you're far away And in my fantasy you crave my body I need you back to stay I've got my inside out and my headache won't stop I fail to not look back as I'm bouncing down the wrong track Half way up feels like going down But I am getting stronger and stronger Uh oh uh oh uh oh Uh oh uh oh uh oh But I am getting stronger and stronger... Midnight turns to morning And I don't get no sleep I know that you are out there somewhere being Someone else's treat Your fingers know just how to please me And chills run down my spine And when you lick and spill your kisses I am shivering inside I've got my inside out and my headache won't stop I fail to not look back as I'm bouncing down the wrong track Half way up feels like going down But I am getting stronger and stronger Uh oh uh oh uh oh Uh oh uh oh uh ...
