with ya current setup you can get some more bandwith with a lower PL and later on try clock twister at moderate (depending on ya ram), in bold are the settings for 500FSB... most important you need more Vcore and NB voltage than with 9 multi and 450FSB...

AI Overclock tuner: Manual
CPU Ratio Setting: 9 -- 8
FSB Strap to North Bridge: Auto
FSB Frequency: 450 -- 500
PCI-E Frequency: 101
DRAM Frequency: 1081Mhz -- 1000
DRAM Timing Control: Manual

DRAM Static Read Control: Disabled
DRAM Read Training: Disabled
MEM. OC Charger: Disabled
AI Clock Twister: Lighter
AI Transaction Booster: Manual
Common Performance Level [10]-- you should be able to get lower Pl here with a divider so with 450 FSB and 1081 ram 9 or even 8 is possible, with 1:1 PL 10....

CPU Voltage: 1.34375 --> for 500FSB ops I need more Vcore
CPU GTL Voltage Reference: AUTO
CPU PLL Voltage: 1.52 --> I need 1.56 for 500FSB
FSB Termination Voltage: 1.22 --> I need 1.26 for 500FSB
DRAM Voltage: 2.12 --> that's 2.20 in reality
NB Voltage: 1.22 --> up 1.26-1.28 for 500FSB
SBridge Voltage: Auto
PCIE SATA Voltage: Auto

Load Line Calibration: Enabled
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
CPU Clock Skew : Auto
NB Clock Skew : Auto


Been taking your advice in this thread and here is where I am right now. P5Q-Pro 0901 Bios, E8400

9X450 100% Stable RAM is at 5/4 540MHZ

Whenever I drop ratio to 7-8 and set RAM to 500MHZ and try 1/1 I get errors in Windows.

anything else ?
prime fails almost right away with threads 1 and 3.

Rusty try more Vcore mate, try 1.35 for a while....
