Yeah, manually set the RAM frequency to the lowest option you can. On your board, I am pretty sure at 400FSB your lowest RAM frequency will actually be 800MHz. Therefore, if you set your FSB any higher than 400, your RAM will start to overclock.

Now thats not a bad thing, its just your RAM might not get over say, 950MHz, limiting your overall overclock. Also to get the RAM any higher than its rated speed, you may need to increase its voltages (to say, 2.1-2.3V) and loosen the timings.

yea 400 fsb my lowest ram frequency is 801. i set fsb to 445 ram freq turn into 846 i think, i up dram volt to 2.20 and cannot boot into window. Probably my memory wont be able to overclock and run stable at 445 ? dont u think so ?

leave your ram at stock work your way up from there, by the looks of it your ram cant keep up with your cpu, or its under voltaged, so try leaving stock timings and voltages,
your ram should be set at 800mhz and manualy set your voltage to 1.8 because auto does keep it stable, set your cpu to 1.3 vcore and ram to unlinked, unlinked overclocks your ram in a circle so if you cant get your ram to stay on 800Mhz, with fsb set at 444 round it off.

whoa did i read 1.37 for 4ghz... that is incredibly high.. my e8500 e0 is pulling that with 1.25v.. which is its vid... i don't think you needa jump that high.. maybe try 1.31 or something around there

So what happens if you do as x3x did in his first attempt: simply crank the fsb to 400 v. 333? Does that also OC the RAM? Cause the multiplier to increase? 3.6 GHz sounds pretty good for very little effort (and a stock cooler).

It doesnt overclock the ram if you have DDR2 PC6400.. 400fsb would be stock for your memory
