Q9450 and P5E3 Deluxe Overclocking Advice

post #1 of 3
Thread Starter 
I have a Q9450 and P5E3 Deluxe motherboard.

I am using OCZ DDR3 - 1333 memory and an OCZ 1010 watt power supply.

When I first booted up even though I manually set the mulitplier to 8 CPU-Z says it is running at 6. Anyone have any ideas why this would switch like that. Also any ideas to get the 8 multiplier to stick.

I was also entertaining the idea of up the FSB to 450 and running the system there. I found a cheat for an older version of the Asus BIOS. I tried these settings but the computer fails on boot up with these settings. I am not to familiar with memeory timings so i left the momory on auto but adjusted the CPU settings and voltages. Any advive would be more than welcome.

That lower Multi, I believe, is the work of C1E, also known as Enhanced Halt State. Your CPU will always push back to the lower multiplier unless it is under load, for the sake of your electricity bill. Try running something that will draw cpu power WHILE CPUz IS ONPEN. That should make your multi change. If you are confused, just disable C1E on the BIOS.
As for not booting, what are those insane memory speeds? ddr1333@1800?!? and that at 1T command, and 7 CAS latency?!? Man, OCZ will call the cops on you.
You might get that 450 FSB allright, but forget 1800 memory (how insane is that?). Try these:

CPU Multi => 8x
FSB => 450

FSB Strap to North Bridge => 266
DRAM FREQUENCY => should be around 1333

**** You can also try FSB strap as 400 and RAM at 1200, for compatibility's sake.

Memory speed => AUTO, don't mess with the speedings yet.

Voltage settings => all auto (leave that for later, you want the machine to boot first. If it doesn't boot, raise vcore slowly. Intel specification for you CPU is 0.85V – 1.3625V, try not to cross that)

Well, that should get you to boot, at least.

..you cant boot your RAM 500mhz over stock speed, without some voltage!

Lower your RAM speed and raise the NB strap to 333mhz for now. Once you get a boot, you can lower the strap to 266mhz [this requires more NBv to do so, as you are decreasing latency].
