Samsung's New Memory Chip Could Lead to 32GB DIMMs

Thanks to Samsung, the first 4GB DDR3 chip has been made available to the world, making them the first to double the maximum capacity of DRAM modules. This advance will allow Samsung to offer high-end, dual-die devices that will support up to 32GB of RAM.
Born from 50 nm process technology the new 4GB monster chips will be made available to servers first, followed by DIMMs fit for desktop computers and then notebook size SODIMMs.
These chips will run at only 1.35 volts, which is 20 percent less than the usual 1.5 volt DDR3 memory that you’ll find on the market today. Samsung hasn’t made any mention yet about the pricing or availability of these chips.

Andy, I think you meant to say 4Gb/4Gbit chip.
When talking about the chips themselves on the memory modules, most of the time they're talking about how many bits there are in the chip, not how many bytes. After all, they want you to feel like you got a lot for your money :)
Since there are 8 bits in 1 byte, these chips are 512MB each. So, a memory module with 8 chips on it would give you a 4GB ram module. 16 chips would give you 8GB and 32 chips would equal 16GB. 32 chips is pretty common for server ram modules (the actual number is higher because server ram is usually ecc).

128GB would be the memory address limit on a 37 bit OS. 64 bits gives you 16 billion GB of memory space. Microsoft still has some time to work with in that aspect.

thats right, the address space of a OS is exponential not linar
thats not to say the bit zise cant be further limited. If im not mistaken a 32 Bit OSt should be able ot adress more then 4 GB of ram but the Consumer level 32 Bit Windows Os can't. Howevber they were rocking windows Servers back in 04 with 128 gbs or ram...

if I'm correct isn't the formula 2^x where x is the number of bits in the OS?

So if I read this right, we could have 96 GB of RAM running in tri-channel mode?

That limit would be 128GB. Are 128bit OS's right around the corner??? Lol.
