Another newbie OC thread

Recommended Posts

Hi guys,


It was suggested to me to post on the forum, so here we are...

I'm quite new to overclocking, and I'd like to successfully overclock my CPU to 3,5 GHz, if it's possible with my setup of course.

Please see my PC Spec, any help is greatly appreciated!

Other things you should know is the Scythe Ninja cooler on the CPU and 3 additional Nexus cooling fans in the case. Current temperatures shown by Everest are: 38 C for the CPU, 32 C for the motherboard, 50 C for the GPU and finally 38 C ambient temperature. Voltage of the CPU and everything else are intact, at the default BIOS settings (mostly auto).

Please let me know if you need any other information.

Thanks in advance for anyone!

This will give you a nice 3.6Ghz overclock.

Download Memtest Version 2.11 from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from

Shut the system down. Insert a stick of DRAM in the first slot closest to the CPU and the second one in the third slot. Restart, Enter your BIOS and Load Setup Defaults. Save Setup Defaults and set to these values:

SoftMenu Setup

JumperFree Configuration Settings
AI Overclocking = Manual
CPU Ratio Control = Manual
- Ratio CMOS Setting = 8
FSB Frequency = 450
PCI-E Frequency = 100
DRAM Frequency = DDR2-900
DRAM Command Rate = 2T
DRAM Timing Control = Manual
CAS# Latency = 5
RAS# to CAS# Delay = 5
RAS# Precharge = 5
RAS# Activate to Precharge = 15
TWR = Auto
TRFC = 55
TWTR = Auto
TRRD = Auto
TRTP = Auto
DRAM Static Read Control = Auto

Transaction Booster = Auto
Boost Level = N/A
Clock Over-Charging Mode = Auto

CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled

CPU Voltage = 1.45v
CPU Voltage Reference = Auto
CPU Voltage Damper = Auto
CPU PLL Voltage = Auto
DRAM Voltage = 2.1v
FSB Termination Voltage = Auto
North Bridge Voltage = 1.35v
North Bridge Voltage Reference = Auto
South Bridge Voltage = Auto

Advance CPU Settings

CPU Ratio Control = Manual
- Ratio CMOS Setting = 8
C1E Suppport = Enabled
Max CPUID Value Limit = Disabled
Vanderpool Technology = Enabled
CPU TM Function = Disabled
Execute Disable Bit = Disabled
PECI = Disabled

USB Configuration
USB Functions = Enabled
Legacy USB Support = Enabled

Run Memtest for two full passes, then (If Stable) enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.

Sorry for the delay...


Thanks for the help, I've done as you told, with the little modification of the CPU voltage lowering to 1,3650V, fearing of burning it. Memtest86+ was stable for the 2 full passes, XP loaded, no problems, 3DMark was stable, but when I ran the Prime95 blend test, core #0 failed after about 2,5 hours. What could be the problem?

I posted a screenshot of the voltages shown by Abit Uguru, too. Oh and in BIOS, the CPU Feature "EIST Function" is enabled, could this affect the OC?

Good overclock. The 1.45V CPU Voltage was to ensure boot. You still can lower it and test for stability. Take your time, every week or so, lower your core voltage one increment and use prime95, then test for a week. Repeat until unstable and then raise a couple of increments. So, set your core voltage to 1.40 and retest. EIST is fine enabled.
