Your settings look similar to mine.
I have the same Mobo and a Xeon 3040 (which is very similiar to the E6300).
Also, I am running stock cooling and
WINTEC AMPO 512MB x 1 DDR2 800 RAM.
Right now, my settings are:
CPU Voltage: 1.325
FSB Termination Voltage: 1.4 V
(G)MCH Voltage: 1.55 V
Memory Voltage: 2.2 V
System Memory Freq: 533MHz
CPU Clock: 400MHz
PCIE Clock Set: Fixed 100
->DRAM Configuration
DRAM Timing Selectable: Manual
CAS Latency Time: 5
DRAM RAS# to CAS# Delay 5
DRAM RAS# Precharge: 5
Precharge delay (tRAS): 18
TWR: Auto
TWTR: Auto
TRRD: Auto
TRTP: Auto
I just started OC'ing this PC today (I got parts for Christmas :-D ), so I am not sure if it will run stable if I lower any of the voltages. I will probably Test it some more tomorrow. I used
wusy's guide to help get to where I am so far.
So far I got Prime95 to run for 30 min with these settings no problem. Hope this helps.
