Below is a message on the Dell community Forum in reply to this question:
"I have had an XPS 600 with the 930 on order for almost 2 weeks now. It was delayed once, and it will likely be delayed again. It's not just a supply problem. Dell pulled the A04 BIOS from the site at about the same time the 900 series processors became unavailable."
My guess is that it is due to the problems with the 900 series. Some work fine, but apparently not enough for Dell. A04 was to fix issues with 900 series processors messing up, so maybe Dell is truly going to use AMD...?
Too bad I no longer work for them, but I know that Intel CPU's in the past 3 months I worked for them have had 8X more failures than the other two years COMBINED (I was 'transfered' around September 30 2005). I still have our callcenter's spec sheets to prove it, nearly 1 in every 17 calls to our Dell support (our callcenter was one of the three or so in US business desktop support division) involved a P4 processor failure. This was averaged for a two week period and 'several thousand' calls.
I'm outa this before Dell finds out I'm...nevermind. Intel recently has been less reliable than ever in short. Their Centrino processors are doing well I hear
I will actually mention one more thing--this was mostly dual-cores and 64-bit cpus. Even with the prescott cpu failure rate, suddenly prescott started looking like a stable processor
Have the prices for the models gone down now that they use the 8xx series again? I haven't been to Dell in a long time so I wouldn't know their regular pricing levels. Intel was supposed to be cutting prices from the 5xx, the 6x0, and the 8xx models to clear inventory at the end of January and replace them with the 65nm 6x1 and 9xx. It's possible that Dell is going back to 8xx in order to offer lower prices and clear their own inventory and the 9xx was made unavailable in order to force users to buy the 8xx.
Going to Dell Canada now I notice the XPS 600 and Dimension 9150 having $300+ rebates. But like I said I can't tell if that is standard bundling or real, new discounts.
I know a bunch of people with 9xx processors, no problem, and they run cooler than Prescott, with amazing speed and overclock potential. Like 4.5Ghz on air, over 5 on water. I doubt the problem is not with the 9xx chip, either that or Dell got a bad batch of processors from a few months ago when Intel just started making them. You get much better quality proc's now then you do from back then. And the 955 especially is a good proc.
I have been also following this thread on the Dell community website and Dell even 'delayed' or more probably 'cancelled' many, many XPS 400/600 systems with 9xx processors that were already in production.
One user said that his system was 'delayed' and not shipped even after it was already in the 'shipping phase'
Dell was unwilling to make any estimates about when these systems would be shipped?
