MSI P45 Platinum Overclock nightmare

Hi.

First of all, my specs:

C2D E8500 @ 4Ghz 1.35V
MSI P45 Platinum
2x 1GB GeIL, 2x 1GB Ballistix @ 1000Mhz 5-5-5-15 2.0V
PowerColor HD4870 512MB 845/975
Corsair HX520W PSU

Mobo settings:

Everything needing disabled I have disabled, like the EIST or w/e (speedstep I think)
1.34V MCH
1.24V VTT
2.050V on the ram or around that.
1.35V Vcore

Spread Spectrum disabled.
Amplitude and CLK control are set to AUTO.
GLT Ref settings also set to AUTO.

Anyway no matter what I do I cant get over 4Ghz stable, I tried playing with amplitude controls and all that, setting GLT Ref settings on the core (ref 1 and 0) and on the MCH but did not help, I also had the voltage raised to 1.4V, I really dont know what to do but it wont budge :cry: 

Any ideas? The guy who had the CPU before told me it can do 4.5Ghz at around 1.4V, I know its not the same on all mobo's, its obvious its not the voltage of the CPU its something else, the mobo is so complicated.

Thanks
Willz.

If I have physical access to this rig, I can guarantee 4Ghz hands down. I'm on E8400@4Ghz on X38 prime stable. Took me less time to get there than with some other boards.

Your settings look around right.

What exactly is the instability? This can help us pinpoint to the culprit. i.e. memtest redlined at which # of test?

I think it was the ram, I had GeIL Ultra 800Mhz at 2.050V, the stock voltage is 2.1V, thought it was 1.9, anyway took it out as I've sold it, was totally stable with the ballistix

I have a TRUE 120 and 2x 2GB G.Skill 8500 coming in the next couple of days.

I'm wanting to aim higher, more like 4.2Ghz.

Are the settings for the X38 similar to that of the P45 Platinum in Bios?

No, it depends on the chipsets. They vary slightly from chipset to chipset. Also, the chipset cooling. i.e. On stock cooling, the vNB/vSB should be lower.

I'm sure with that big heatpupe setup that is on the P45 1.4V MCH should be possible.

Hi.
You have to put memory voltage 2.1 Volt and BOTH REF MEMORY VOLTAGES 0.955 Voltages. Auto specs in this uses too high voltages and thats causes crashes.

hi i have got same prob. as Willhub i can´t go higher thnat 400FSB so my cpu speed is 3.6 Ghz i dont know what to do i tried everything MCH v. VVT or ram vcore everything all stupid technologyes is put to disabled

my computer spec.
CPU E8400
RAM 4GB 800mhz -> i can oc them to 1000mhz
board msi p45 platinum
Power color ati hd 4850
PS Tagan 480W easy con series

I am planning on buying this board tomorrow or thursday. How well will it overclock my E8200 with OCZ ReaperX 1000mhz DDR2 2.1v dual copper heat pipe memory and a Corsair H50 liquid cooling system for the CPU?
