Is the same speed ram with a higher voltage better or worse?

I bought some ram from new egg, it was supposed to be 2.1-2.3 volt 5-5-5-15 1066 2 gig sticks, but I was send the same speed only 2.3 -2.5 volt type. Do I wanna get the lower voltage chips, or does it really matter?

Any explanation would help!

(GeIL evo one 2 x 2 gb pc1066 5s rated at 2.3-2.5 volts.)

Hmmm, okay, I think I will give them a call. The add says 2.1-2.3 volts, and the RAM they sent says 2.3-2.5 volts. Anyone else have an opinion on this? (They do have the double height heat spreaders!) I was under the impression that as long as you run it at its rated voltage. ::shrugs.:: I do have decent components! Need input!
Like... anyone else use the things?? Evo One 2 x 2 GB kits. Got 2 pair, hehe!

Wow, that actually made sense. I guess I see what you mean. I will get on the phone and get the lower voltage ones as they claim. I wasnt thinking clearly enough on the subject. The lower the voltage at whatever speed, the better quality of ram it must be, because anyone can add voltage to gain a lil speed. Its called over clocking, imagine that!

Thank you very much!
