3 long beeps after putting in new board

January 4, 2011 at 09:30:17
Specs: Windows XP
My Lexington board went out after 8 years so I bought a brand new identical one and reassembelled everything, with a new Radian AGP video card also, and when I turned it back on I got 3 long beeps and no startup. I didn't leave it on after that and have not tried it again. I have been trying to read up on the problem but haven't been able to find anything for this board. The chipset is Intel i850 or 1850. The memory is 1g Rambus and a 3.2Ghz processor.
Thanks Rick D

Why would you bother replacing such an outdated board? Especially one that uses RDRAM? Hopefully you got it for about $10.

I believe 3 long beeps means there's a problem with the keyboard.

I tried it with the keyboard unplugged and still the same result

The Lexington mboard is an Intel OEM only mboard model - it was only sold only to brand name system builders.

"3 beeps - Base 64 K memory failure

* Reseat the memory.
* Make sure that the contacts on the memory and the socket are clean.
* Try removing one bank of memory modules at a time. Note: Some systems might need to have a memory module in Bank 0.
* Try using RAM chips from the same manufacturer with the same part number and speed.
* Check for a faulty memory module by trying the memory in a known good system.
* Trying known good memory in the system.
* Check the power supply and check for power fluctuations."

MAKE SURE that you have the RIMM ram installed properly !

Which Radeon video card did you get ?

If you have trouble with your video after you fix the 3 beeps problem.......

Your mboard supports max 4X AGP specs.

NOTE that SOME main chipsets that support 4X or 8X AGP CANNOT use a video card with a video chipset that also supports 2X AGP specs. Doing so will so will result in no video from the card, and in a short time, damage to the AGP slot circuits, and possibly damage to the video card and the mboard otherwise !

See this - scroll down - it shows you which ATI video chipsets support 2X AGP as well as 4X or 8X :
