Wouldn't usually start a new thread for this, but the source of the problem is baffling.
My FSB hits a wall at 415mhz. Now originally i thought this was my RAM, capping me at 830mhz, but changing ratio to 4:5 gives me ~1040mhz. So we know this is not the case.
BIOS settings: (Note the template here is for BIOS 404, i sue BIOS 504, but all but a few settings are the same:
JumperFree Configuration Settings
AI Overclocking: Manual
CPU Ratio Control: Manual
- Ratio CMOS Setting: 9
FSB Strap to Northbridge: 333Mhz
FSB Frequency: 375
PCI-E Frequency: 100
DRAM Frequency: DDR2-750
DRAM Command Rate: 2T
DRAM Timing Control: Manual
tCL (CAS# Latency): 4
tRCD (RAS# to CAS# Delay): 4
tRP (RAS# Precharge): 4
tRAS (RAS# Activate to Precharge): 12
tRRD (RAS# to RAS# Delay): auto
tRFC (Row Refresh Cycle): auto
tWR (Write Recovery): auto
tWTR (Write to Read Delay): auto
tRTP (Read to Precharge): auto
DRAM Static Read Control: Disabled
Transaction Booster: Disabled
Clock Over-Charging Mode: Disabled (this is different in BIOS 504-mine,template is of 404)
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
CPU Voltage: 1.45v
CPU Voltage Reference: 0.63x
CPU Voltage Damper: Enabled
CPU PLL Voltage: 1.60v
DRAM Voltage: 2.10v
FSB Termination Voltage: auto
North Bridge Voltage: auto
North Bridge Voltage Reference: 0.67x
South Bridge Voltage: auto
Advance CPU Settings
CPU Ratio Control: Manual
- Ratio CMOS Setting: 9
C1E Support: Disabled
Max CPUID Value Limit: Disabled
Vanderpool Technology: Disabled
CPU TM Function: Disabled
Execute Disable Bit: Disabled
PECI: Disabled
Now, my spec is in my sig. What could be possibly stopping me going past 415mhz? The chip can: Fact, The motherboard can: Fact, the RAM can: Fact. I've been blaming hardware, i.e. RAM for ages on this, but it's clearly something more, any insight?
Please note: This is not a clock speed issue; at a lower multiplier the cap will remain the same.
Thanks in advance.
