I wanted to overclock the C2D E4600 on the P5Q-E but the later always fails at start-up.
I increased the FSB by some 10MHz but even that it failed.
Anything I do fails.
I left everything on Auto except for the FSB.
Could the CPU be the problem or it's the motherboard?
Something I noticed is that the EPU-Engine overclock the CPU but it never crashed but if I overclock the later in BIOS it crashed and restart at Start-up. That's weird!!!!
I'm upgrading to the Q9550. I have already ordered it.
C2D E4600 @2.4 GHz
Antec Trio TP3-650 650W
2GB Corsair XMS2-DDR II 800MHz
Sapphire HD 4870.
Could be your RAM... if you have it set to 800mhz (as it should be) youll be running DRAM:FSB at 2:1 if this is hard locked at 2:1 increasing the fsb by 10... 210 FSB will automatically set your ram to 840mhz... although most ram will have 5-15% headroom you might need to increase voltage to do so.
Suggest making sure your RAM is running at 1:1, download CPU-z and check memory settings to confirm
According tho the motherboard the RAM can't be run below 800 MHz.
I locked the RAM so that it doesn't overclock as well and I got no result.
Since everything blocked at POST then it's impossible to run CPU-Z.
What I don't understand is that the Asus EPU can overclock the later by 5-10% without any issues but I can't change anything in BIOS...
Normally that should be very easy because this motherboard is reputed to be very good at overclocking...
