I've been making the switch to LGA775 so I've been looking at DDR2. In the specs somewhere they usually say that DDR2 takes somewhere around 20% less power to run. I've also seen this said about the prescott compared to the northwood because the prescott can run anywhere from 1v to 1.4v, where the northwood typically starts at 1.52v, but we all know the prescott takes many more amps.
I had a PSU problem, and I sent it in for an RMA. I didnt want to be stuck on my laptop so I put the 350 watt in from my P2 system. It has a 12a 12v line, and it's powering a 530J, 2 hard drives, and an X700 Pro. It's JUST BARELY able to handle it. My benchmarks are really showing a lack of power though, I really hate doing this, hopefully my power supply will be here soon. I am running a hybrid LGA775 board for now, and my DDR2 came. It's 512x2 PC2-5400. Currently I am using the RAM in my sig, which is only 256x2.
I put in the full gig and I was able to get into windows, I ran a sandra mem bandwith test, I think I got around 3gb/s, them the system turned off. Sounds reasonable, I can't expect much out of the 350watt. So then I took a stick out and ran only one 512mb stick. It turned on, then off. It just couldn't power it. I put my old RAM back in, and it did it just fine. I was running them DDR2 at the same speeds as the DDR1, and there was the same amount of it(512mb), yet it couldn't power the DDR2.
So to me it looks like DDR2 does take more juice to run than DDR1. I wanted to know for sure though. My DDR1 runs at 2.6v, while my DDR2 was at 1.8v.
This will be my 3,000th post! Woo Hoo!
