Help Intel E6420

post #1 of 10
Thread Starter 
Hi, I have an intel e6420 standard 2.13Ghz.
Firstly I upped the core to 2.4Ghz with a max multiplyer of 8.
The system failed to boot a cuple of times, but then automatically loaded successfully with the 2.4Ghz speed.
I then ran a stress CPU and RAM test on ORTHOS for 8 Hours, a good time to see if stable.
The test results said that my CPU was stable.
So why did the system fail to boot a cuple of times??
From what I have seen this chip can be pushed to over 3Ghz with ease, so why am I having problems at 2.4Ghz?!?!?!?!
Everyone reply with suggestions and answers.
Thanks.
Will.

You may need to raise your CPU and MCH (NorthBridge) vCore a little to maintain stability.

Section II: Setting Overclock Parameters.

For the 965Pand E6400 You should be able to easily hit 3.2 ghz using the 8.0 ratio.
First go into the bios and change overclocking to manual. Slowly raising these settings is best in the overclocking, but if you are lazy you can start at the top. Let stability be your key.

# vCore: 1.375
# vFSB: 1.300 (Auto)
# vNB: 1.3 (Auto)
# vMem: 1.8 - 2.45 on ASUS Boards. Default on DS3 is 1.8 and moves in +.1v increments. Find the maximum your warranty will allow.
# Configured FSB: 400 x 8 = 3.2ghz, May be less or more depending on processor.
# Memory Ratio should be 2.0 on DS-3, DDR2-800 on P5B
# Configured Ratio: 7 (E6300), 8 (E6400), 9 (E6600), 10 (E6700), 11-50 (X6800)
# Configured Memory Timings: 5-5-5-15/4-4-4-12 (Configured under Chipset)
# C1E and SpeedStep off, Locked PCI Express Frequency locked at 100, PCI Sync Mode at 33.33.

Hope this helps!!

Your motherboard is a GA-965P-DS3 .....so you have a 965P chipset.

Disable any Spread Spectrum options in your BIOS along with any CPU features, such as C1E, EIST, Virualisation, Execute Disable BIT, etc... Also disable all unused motherboard devices, such as networking ports, and also disable any Legacy options.

As for voltages, I prefer to adjust them manually, so I think you should raise your MCH voltage to about 1.4v, rather than leave it set to AUTO. The same goes for your CPU vCore. Your E6420 should cope with 1.425v easily enough.
