Exceeded the 4GHz

[Big B]

I can not pass the bar 4GHz!

As soon as I increase the fsb of 5 PC starts but it tells me a message: No drive found (or they are there!)

My setup is as follows:


1 Hard Drive Western Digital Raptor X 150Go, Sata 10000/tours/mn
Motherboard ASUS STRIKER II EXTREME nForce 790i Ultra SLI DDR3
Power Supply Gigabyte Odin GT800 Watts
Processor Intel Core 2 Quad Q9450 3.9Ghz
Memory Corsair Dominator 1333 1 GB X 4 (4 GB) 1333 9.9.9.24.33 2T
Cooling: Watercooling
DRIVERS ForceWare: 181.22
DRIVERS Motherboard: Nvidia nForce v9.64
BIOS of the motherboard version 901

Windows XP sp2

The problem is that the Pc OCCT passes but it refuses to mount more!

Thank you for your help

You happen to boot @ 6x500? and if you can drop your vcpu.when the "no any drive found" it happens with an unstable oc!

The VNB which seems rather low for nForce . I push my 680i @ 1.6 v

[Big B]

I tried:

FSB: 500

Over Voltage:

CPU Voltage = 1.45
Calibration = Enabled Loadline
CPU PLL Voltage = 1.68V
CPU VTT Voltage = 1.5V
Memory Voltage = auto
NB Core Voltage = 1.64V
SB Core Voltage = 1.60V


Sometimes at the office until then hangs loading programs!
