Hy! I have an Asrock P4i65G with 2x256MB 400(!)Mhz DDR RAM and in the bios cant change DRAM Frequency, greyed out at 266Mhz. Any solution to unlock this settings with bios mod or anything else? I already used 2.1 slic modded bios from this forum(thx) but problem still persists. And for that matter have a Sapphire Radeon HD3650 512MB video card, but when i plugged and powered the pc, received no signal on the monitor and hdd led constantly light. Should replace power supply? I have included aida64 report to more help, but here is PC: M-tech 350W (12V1=13A;12V2=10A) Asrock P4i65G: latest 1.40 2.1 SLIC modded bios Intel Celeron 2600Mhz 400FSB (i know if would have an 800FSB proc i can use 400mhz ram, already tried 400->800FSB BSEL pin mod, but no boot) DDR 2x256MB 400MHz 3 IDE HDD+1 ODD Integrated intel extreme 2 graphics Thanks in advance for your help.
