KHX8500D2K2/4G manufacturer voltage is?

[xxgg]

Hello. I am currently using KHX8500D2K2/4G on my Gigabyte EP45-UD3P motherboard and have it running at 5-5-5-15 @ 2.3v Kingston Technology Company - Kingston Memory Search - Search Results for: KHX8500D2K2/4G My question is... just like the link I have posted memory module label show as 2.3v BUT, on some sites even from Kingston website sometimes specs are shown as 2.2v Regardless if it's stable at 2.2v or not, I am guessing it is 100% stable at operating at 2.3v, right? Or do you guys think 2.3v is little too much? By the way, will there be any problem with putting another 2 more stick for total of 4 dimms on my motherboard?

Are you using a 64bit operating system? Like Windows Vista 64bit. If so you can ad more memory. 2.2 volts should be fine considering that Kingston specified at 2.3v ± .1v and that Gigabyte board already has a slight overvolt. You can confirm that by going into your bios and look in PC Health Status. I got mine at 1080Mhz@1.95
