I'm shy about saying what is compatible because sometimes Dell upgrades can be a little quirky. I love Dells, and I think they make a great product at a low price, but I don't ever recommend them for someone who has the intention of upgrading the CPU or MB.
Shouldn't be the socket and the chipset be enough to know what's compatible
It should, but it's not the case with Dell.
If you're planning on a new system come summer I don't think it's even worth it to consider a cpu upgrade for the Dell at this point.
Google "Clockgen", it's a software overclocking program that work's on Dells and will probably allow you a gain of 4-600 mhz with your current cpu.
I found an old post; looks like the board doesn't support the newer core2 duos. Only the old p4's. The 3.4-3.8 cpus are available, but tend to run warmer and may require a heatsink upgrade over your standard dell. I would leave it alone; start saving for a new system. Even some of the $300 systems will outperform your current one.
Okay. I talked for a while with the Dell Support Chat and after a little research he told me the only CPUs working with my MB/Chipset are Prescott, Smithfield and Presler. These are the best of each working with it:
- Pentium 4 660, Prescott, 3.6GHz
- Pentium D 840, Smithfield, 3.2GHz
- Pentium D 960, Presler, 3.6GHz
Tried "Clockgen", but my PLL (CY284100XC) isn't on the list. Which should I use?
BTW again: Does the Pentium D 820 support x64 OSs? Win7 x64? Good Idea?
