If you're thinking of carrying out a Core i7 upgrade later this year, you're probably going to want an X58 motherboard, a CPU cooler that supports socket LGA1366, and some of that tri-channel DDR3 goodness.

On the DDR3-front, some of the first tri-channel kits to be branded as "ready for X58 motherboards" have come from Taiwan-based A-DATA.

It's today announcing production of DDR3 1600 and DDR 1333 tri-channel kits in 3GB and 6GB capacities. It expects availability in this quarter, with prices starting from $230.

The DDR 1600Mhz kit has been tested in tri-channel configuration with latency settings of 8-8-8-24 2T. The 1333MHz kit has been verified at 7-7-7-20 2T.

A-DATA's recommended retail price for the quicker DDR3 1600 kits is $230 for the 3GB model (3x1GB) and $350 for the 6GB model (3x2GB).

inevitable really, lets hope the DDR3 price drops :)

Intel is adivising mobo-makers and memory vendors alike about their new X58+Core i7 combo and to abide to a strict 1.65V limit on memory voltages, beyond which there is the risk of burning out the CPU.

So… there goes overclocking and any “performance” ram as the high speed ram takes 2v usually.

So whats up with cooking your cpu by using higher ram voltages? Is this pointing to no overclocking for Nehalem?
I guess the memory and CPU voltages are linked in some way. We will only know in time if there is a way around it, or if the memory manufacturers can released faster-then-needed RAM that falls within an acceptable voltage range. We also do not know if this could be a moot point for overclocking…….higher RAM voltage = higher CPU voltage……..when your overclocking you frequently raise the CPU voltage anyway. Until we know the actual effect one has on the other and what is “safe”, its all guesswork.

As for DDR3 prices, they will continue to slowly fall but it's going to take a massive shift in the market before they reach current DDR2 pricing.
Isn't the i7 the first Intel chip with an integrated memory controller?

That would explain Intels position on memory voltage.
So i understand, loosely, that Intel have followed AMD's path of an integrated memory controller and therefore no true front side bus any more.
But i still think in FSB terms, looking an memory speeds, overclocking etc (i guess hard habits etc).

So… if this is tri-channel, each at 1333 Mhz (and i can't remember - does this mean 2666 each effective data rate?), so we have 2666 x 3 Mhz of data bandwidth = 8Ghz …! Are my calculations correct? If so, how would the CPU use this much? Back in the P4 days they had 4 x 200 Mhz, have we jumped ten times since then?
