Now stuck

[tommchowat]

Hi guys,

First, my system:

E7400 2.8 @ 3.6GHz
4GB (2x2GB) PC8500 RAM
512MB 9800GTX+
Asus P5KPL-AM Motherboard
Xigmatek cooler + Noctua case fan

Basically I'm now stuck with this overclock. This motherboard's FSB is rated at 1600MHz but I just can't get it there. The bad thing about this board is that the FSB:RAM ratio cannot be changed, it's changed automatically depending on other settings. My current settings are this:

Multiplier: 10.5
Vcore: 1.392
RAM voltage: 2.1
Bus speed: 344MHz
Rated FSB: 1376MHz

I've attached pictures of cpuz and the BIOS. I cannot get the bus speed above 344. I've tried 345 but get a no POST, I've tried different combinations of bus speed and multiplier, different RAM speeds, but it always ends in a no POST. I'm dying to get this thing up to 4GHz, but I don't know the magic combination that might do it. Does anyone have any ideas?! I've attached pictures of all the info you might need but if you need any more then please ask!

Thanks.

hummmm try with just one stick of ram, when i was doing mine sometimes when trying out speeds it wouldnt post but when i used only one stick it would be fine... then once saved and i put in the other sticks it would be fine

Nope Didn't work.

Thanks for that info. I just looked up a BSEL mod and apparently this board won't accept it. I tried upping all available voltages to the max possible, including the RAM at 2.2V, but the thing still won't accept anything above 344MHz, it's driving me absolutely insane.
