Fastest CPU for XW6400 and XW8400
Whilst on ebay a week or so ago I noticed that there were some used processors for sale that I might try in my XW8400.
This page might also be interesting if you have a Max Pro 2, as these use the same generation of processors as the XW8400, also the Dell Precision 490. However I do not own a Mac or Dell!
In the quick specs document, the XW8400 and the XW6400 are shown as using:
52XX (5200) and 54XX (5400) Series CPUs in XW8400 and XW6400
Since the release of my XW8400, HP have launched the XW8600, and its little sister XW6600.
These use the processor families (THEY DO NOT WORK):
The cheapest I could find on ebay that would have improved performance on my machine was the X5260, which is a 3.33 GHZ , 1333 FSB, 6 MB, 771 Processor. I bought 2 for £5 each so throw away money really.
THEY DO NOT WORK. I tried both just to make sure and the machine will not start, I replaced the original processors and she booted. So that is a shame no upgrades for me. I would 99% assume therefore that all 5200 series processor will not work. And I would 95% assume that all 5400 processors will not work.
So what are the fastest Xeons for the XW8400 and XW6400?
So to conclude the fastest processors for the XW8400 and XW6400 are:
Xeon 5170 at 3.33GHZ . . . .
Well it is not listed on the Intel website so rather disappointingly this is either a typo, or a ghost CPU!
