ok ive got 8 gig of reaper 1066 heatpipe in my machine , i run it at 800mhz as the MCH cant handle 8 gig at 1066 easily without seriously slackening timing so tight timing at 800mhz is more stable , now the question i need answered is , the jedec says 1.8v for voltage @ 800mhz , the rams stickers say 2.2v at 1066mhz , now do i trust the jedec spec or should the ram still be at 2.1-2.2v even at lower speed?

You can trust the JEDEC specs. You need more voltage to overclock to 1066Mhz, but 800Mhz should run stable at 1.8V. A bit more voltage should allow for tighter timings.

cool thanks , thats what i thought , ill try 2.0v and 4-4-4-12 2t later , ive heard the ocz reaper tighten up pretty well and 800mhz with those sort of timings are better than 1066mhz with slack ones

Very few people realize that 800Mhz at tighter timings is as good as 1066Mhz at looser timings.

Use CPU-Z and look under the SPD tab, it will tell you what the settings for your RAM are @800.

aye thats what i did , thats jedec spec though , which is pretty liberal / relaxed tbh , playing around with the timings atm , im running my cpu at 3.6ghz for stability atm , used to run at 4ghz but i wasnt happy with temps for day to day use , good thing is at 3.6ghz the memory ratio is 1:1 with 800mhz setting which seems to help performance also.
