Okkultus Posted March 30, 2009 Share Posted March 30, 2009 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!

DerekT Posted March 30, 2009 Share Posted March 30, 2009 This will give you a nice 3.6Ghz overclock. Download Memtest Version 2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from HereShut 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 = EnabledRun Memtest for two full passes, then (If Stable) enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.

Okkultus Posted April 2, 2009 Author Share Posted April 2, 2009 Hello, 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? http://i159.photobucket.com/albums/t121/Okkultus/cpu-3600.jpghttp://i159.photobucket.com/albums/t121/Okkultus/memory-2699.jpghttp://i159.photobucket.com/albums/t121/Okkultus/spd-2.jpg http://i159.photobucket.com/albums/t121/Okkultus/voltages.jpg Link to comment Share on other sites More sharing options...
DerekT Posted April 2, 2009 Share Posted April 2, 2009 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. Link to comment Share on other sites More sharing options...
