Choosing DDR2 Ram and PSU

[Halcyon]

Right, well I apologise for yet another topic about my new PC, but I promise this should be the last one.
I've finally decided on what to buy (and am not going back) and its all based around the new LGA 775 Intel chipset and will be built on to this motherboard:

Now I cant afford to put in two sets of 512 DDR2 RAM so I am wanting to put just one lot of 512 and then eventually add another 512 later on and take advantage of the dual channel.

So If I want to just stick in 1 lot of 512 DDR2 RAM, can I do this.
And then a few months late I'l stick in another 512.

Im not sure which one to get out of these two:
Any guidance would be helpful.

This RAM or is it This One Instead I need ?


My other question is what wattage PSU do you think I would need ?
It says I need a PSU with a 24 Pin ATX power connector and a 4 Pin ATX 12 volt conector.
Are these present on all PSU's ?

A big thankyou to everyone who can help.

If your going the LGA 775 route, I'd wait for the 1066MHz FSB m8, if you can't wait just get a socket 478 P4 or Athlon 64.

How long do I need to wait for the 1066MHz FSB ?

I think Im tired of going round looking up computer stuff and just want it now so I can build my machine. How much differnce would a 1066MHz FSB do ?


Anyone know for the Ram and PSU info ?

Thanks.

Basically, if you go LGA 775 now (800MHz FSB), it will cost you more and you probably won't get much of a performance improvement, if any over a decent socket 478 setup. Don't be fooled into thinking DDR2 is some awesome jump over standard DDR modules, the latency is through the roof, which isn't good. Personally I'd go for a setup similar to mine, see sig

The OCZ RAM I have is low latency and capable of running at DDR500 and higher. To get the best out of any system, you should match the FSB of your CPU with your RAM clock speed to get a 1:1 ratio. That's why I got the PC4000 modules so when I overclock my Prescott, I still have a 1:1 ratio, I currently have them synced at 240MHz FSB (x4 = 960MHz).

Plus PCI-Express is going through a teething phase at the minute, it's new tech' and in a lot of cases is out performed by AGPx8. Another downside to LGA 775 is the fact that Intel decided it would be a good idea to place the pins on the motherboard instead of on the CPU, so be very careful. Don't forget the 875P is a mature chipset, it's a tried and true architecture with brilliant performance and overclocking potential. Abit IC7-MAX3 or Asus P4C800-E Deluxe are the best 875P boards on the market.

As for the PSU, I'd recommend Antec or Enermax around 500w

After some digging around, it seems the 1066MHz FSB Prescott core also features 2MB of L2 cache, that's twice as much as the current core. The "F" series Prescott will also debut with Intel's answer to AMD's 64-bit extensions, known as EM64T Technology.

The new LGA 775 CPU will appear later this year.

Thanks for the info.
I'm going to have a long think over the weekend about what to choose.
