Whats the relation between tighter timings and voltages 0n ddr800? * +

you often have to up the volts to get tighter timings but not always. most ddr2 will run at 1.8v stock timings, overclcoking ram may need mor volts normaly between 1.9-2.2v to help with the faster mhz and tighter timings. tightening the timings should be done after your speed if your trying to get the fastest possable speed out of your ram, but lowering the cas latencey is the 1 that brings the * +

biggest rewared as far as efficent timings go. the other timings will give between 1 and 2 percent between them while the cas latencey will give 2 percent on its own not a huge amount, you say!. thats why you tighten them after you increase the mhz as its the mhz the bring the real speed as much as 10 percent. can be had in total by mixing the 2 tweaks. * +

but a word of caution, if you dont have good heat spreaders on your ram dont overclock it as the extra heat generated by the extra volts will have nowhere to go and will burn your chips. no1 likes burnt chips... also not all ram will let you drop the cas latencey, as its already been done at the factory, its 1 way of selling cheap ram as performance ram. transend often do this with there budget * +

ram, they have been known to add a cheap but nice looking heat spreader, and change the jdec values. then rebrand it as low cost perfomance ram. * +

the lower the timings the faster the memory. If you push its clock rate up the timings will increase and the memory will actually perform slower due to latency. That's where the above what Jaymack has mentioned come in. Cheap ram will get murdered by latency while your general overclocking ram will run a higher clock with less latency because its guaranteed by the supplier to run at that speeds. * +
