bro,just go to bios and set the vdimm to 2.6 and adjust ur timing,that's all,if u have good chipset,it can run perfectly.
sometime i do CL5 with 1350MHz,but cant really stable,pas super pi 4M but failed 32M :sweat;

2.6vdimm with a intake can cool it perfectly,i dont feel any heat around the heat spreader when i touch the ram on 2.6vdimm.

your rams are a prodigy not much can do 1.2ghz @ 2.6

i get a mushkin basic ddr2 800 with promos chip i guess
i can do ddr2 900 cl4-4-4-18 @2.2v

my mushkin ddr2 667 is now doing 800 at 2.1 vdimm (5-5-5-15)..can i do CL4 at higher vdimm, let say 2.2-2.3v? wont damage my rams rite? does a heat spreader really helps? thanks..

I have mushkin value 667 doing nearly(7mhz short) 900@2.2v with 4-4-4-15
And i have the heat spreader with fan from heatsink blowing to it.It does feel warm.but not much laaa.

very nice timing wor.............. hehe.........

i have mine runnig at 4,4,4,12 @ 800...........2.05v .......no heat spreader but i have a 120mm fan blasting it hehe.........

My Mushkin DDR2 667Mhz 1gb can run at 888Mhz 5-5-5-15-22 Timing @ 2.1v

Cannot go more coz my T550 mobo don't support higher voltage unless I use the jumper .. MY casing no fan at all .. Don't dare to try ..

was mushkin memory cheaper thn corsair and kingston? overall it is also a nice ram rite? im also thinkin to grab for dual channel

i think u can get cheaper for kingston and corsair value ram
but mushkin new packing much more intresting
if u do not do very high FSB like over 500 this ram is very value for $$
and likely can work under high voltage oso
i am running my value 800 for few month with 2.3v with no fan

this is a good ram from my experience. with a good price too. able to overclock my E6550 to 2.7ghz ( can go higher ,but maintain at 2.7 bacause only using intel stock fan and all in stock voltage)

dude go push more, all c2d's are meant to run 3ghz and above

cannot push anymore. now my 12V become 6.5V already . plus, my system cannot setup together with my Type-R modular psu (580W). i try with acbel 390W , can.dunno what a problem. trying to survey psu now.huhu

may be ur psu's capacitor kaboom edy
the hardware section got silverstone review seems value for money!!
