New to this forum - any assistance would be appreciated.
I currently have a Prescott Pentium 4 540 CPU 3.2GHZ (SL8PY ??) with an OJ3492 motherboard and 925X chipset. I understand from reading previous posts I should be able to upgrade to any Prescott Pentium 4 6x0 series giving me then 64 bit operation, however when I look at the Prescott 6x0 series they say that compatible chipsets are 945G and 945P. Does this mean I am snookered or are they backward compatible?
I can't seem to find a P4 6x0 series compatable with 925X chipset. Or am I looking for the wrong thing?
Solved! Go to Solution.
Yes, they should be compatible,
I installed a Socket LGA 775, 660, 3.6Ghz processor in one of my Dimension 8400 with a 925x chipset, without issue.
Prior to installing the processor, check that you have BIOS Version A09 installed, when support for newer processors was added.
There's no need to upgrade the power supply, for a processor.
Remember to clean the heatsink's base and replace the thermal compound.
I have a 3.2 cpu installed in a 8400 IF i install the highest speed cpu available will i see any difference in performance or is the difference to small to notice and therefore time for a new machine, i have installed win 7 32bit which runs ok but we all need more speed don't we.
You should see a small increase in performance, but may not be worth the cost of the upgrade, as only single core processors are supported by the 8400
Maxing out the RAM would be a better upgrade and maybe the video card, depending on what PCIe x16 card, that's installed now.
Agree with Bev - there is a very small increase in performance but that is offset by the increased fan noise - see my post "Dell Dimension 8400 CPU upgrade - Success". The cost of the upgrade was just a couple of pounds but I eventually reverted to the original CPU because of the fan noise. Now looking for a 650 CPU that will give me 64 bit operations, or perhaps a new box.........
Many thanks guys, I have allready updated video card (Radeon 5570) & 4GB Ram some 12 months ago running Windows 7 32 bit So looks like digging into piggy bank and looking for new machine need fast machine to process large files in photoshop
