If you are getting a message that the microprocessor failed the bios test, then there is likely a serious problem with your processor. You can try removing the processor and then putting back in, as well as making sure the processor fan is working properly, but if that doesn't work, you will need a new CPU.

Dell Precision 530 with dual Xeon CPUs. Uses Rambus memory. (4) 256mb ECC modules are installed. It should be a total of 1 gb. However, BIOS only shows 256mb total even though it shows all 4 rambus...


It sounds like like you have multiple issues. When all memory slots are filled with 256 sticks the computer boots but only sees 256 MB instead of 1 gig.
When you install the Crimms it won't boot at all.
You may have an open circuit on one of the Crimms.
As for the computer seeing only 256 MB you may have a bad memory slot on the motherboard.
Here's a link regarding Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM: http://en.wikipedia.org/wiki/RDRAM

Presario won't recognize second 256 RAM


Remove the original module, install just the new one and then start your computer. If it doesn't start, the memory you bought is bad. The system boards used in the Compaqs will auto-detect memory, and there are no jumpers or BIOS settings needed.

MEMORY UPGRADE


Sorry for the delay in my response.

Your computer will accept a maximum of 1 GB of memory. If both memory modules are the same brand and part number then it is possible that one of the sticks are bad.

Try each 512 MB memory stick in the first memory slot, without installing a second stick. This will troubleshoot to find out if one of the 512 memory sticks are bad. If both check out ok, then the problem is with the video adaptor.

Have you tried adjusting the refresh rate on the monitor as I described in my first response?

My final possible solution would be to upgrade the bios. Below is a link to the webpage for your computer system. You will find links for troubleshooting guides, driver and software downloads, product specifications, etc. If you click on driver downloads, then choose your operating system, you will be directed to a page that should provide the latest ROM (bios) update.

PC turns on then quickly turns off


Does it boot fine if you remove the memory you just added? If it does then try switching the memory that was in it before with the memory you just added. You want to first determine if the ram you bought is bad or incompatible.
