Ram voltages

hello, i looked on bios by pressing f2, and next to memory it says 1024MB/333mhz (DDRII 667), and when i look into another section it says 1.5v, i am thinking of getting 2 matching ram sticks both 1gb and they are 1.8v, if i plug these in would my mobo recognise them and move the voltage up? i don;t even know my max voltage.

on bios you can change between normal and high but i tried changing the normal 1.5v to high, which does not say how much voltage, it tells me 'this is read only' so i can't change stuff.


i am running on conroexfire-esata2 mobo, 667mhz max for ram, 4 ram slots, 4gb max and i currently have x1 gb ram in. win vista32bit

in an ideal world the MB will up the voltage and run at the lowest common specs, in practice you get about a 60% success rate with miss matched chips.

if you currently have 2 512mb sticks then I would get two more, if it's 1 1gb stick then get one more 1gb stick. Doubling your ram from one to two gb will give you a nice improvement

The best way is to get the exact same sticks down to the model number, but seeing as that is often impractical you should get matching sticks speed, cas, voltage, and size. If you can't find the exact same specs get the closest you can find.

So if i get a pair of 1gb ram to make up 2gb ram, it doens't matter about the voltage? i was wondering if the MOTHERBOARD had a 'cap' on the voltage allowed by my ram, as in a motherboard specific thing, e.g. can't run 600W graphics card on 250W psu

yes the mb has a cap on voltages; no you are not going to exceed that cap with stock voltages, that only becomes an issue when overclocking

what ever you do the sticks need to match
