U never state ur mobo so i assume the normal overclockable mobo settings. Ur ram can keep 1333 as long as ur multiplier or divider is correct. Make sure it's at 1333 no higher but if ur using kvr 1333 u should be able to hit 1600mhz if it's using elpida chipset. I tried most kingston also manage to hit 1600 juz mebe timing around 9 9 9 27 or 28 wif 1.65v dimm.

I duno why but I always like to make my fsb 200. I kept wif x58 and 1156 coz both can hit 200 fsb sandy is kinda lock around 100mhz so i never venture to this.

Just keep in mind max vcore is 1.35 - 1.4 so ur safe if it's 1.35 or below. The rest is juz up to u to test and feel.

If h55m u need to watch out for ur vrm temps, those mosfets or chips there tends to go very hot if o/c and especially 200 fsb. I blew up a few H55 and P55 when I never watch out for the temps and voltage. Higher fsb usually is harder for certain mobos. Make sure never run ur vcore higher than 1.4 safest is 1.35 and pll vtt those I remember must be around 1.2 or something never higher. Do check those p55 club forums for better understanding as it's been quite awhile I kinda forgoten those specs.

Btw juz a pic of my noob o/c.



I try to dig out the 4.2ghz on P55-UD6 but that confirm blew the mosfet or mobo due to the 1156 fiasco coz of foxconn socket problem. Mainly I believe is the cover and not socket coz it couldn't push the processor down enough to have tight contact wif the connectors.

Lower than 1333mhz then u should tighten ur timings. If it's elpida u should be able to run 9 9 9 24 or 9 9 9 26 for 1600mhz. But make sure u can pump 1.65 vdimm. Else if below 1333 8 8 8 22 or 7 7 7 21 should be possible. Ram timing really not that important when ur tryin to aim for overclock coz usually u try to get a stable clock 1st then only tighten ur ram timing. Some people use lower ram clock so u can ensure the pc stability is not hindered by ur rams.
