EPoX EP-8K7A+ motherboard - memory problems

Dear FixYa: I have enjoyed my EPoX EP8K7A+ motherboard for several years. I have been using 512 Mb of RAM until a few days ago, when I attempted to upgrade my memory , using two 512Mb, PC2100 DDE 266MHz DIMMS. For some reason, only the first 512 Mb is being recognized during the POST (it indicates 524288K). While the system analysis program I used (Belarc Advisor) sees both DIMMS ("Slot 'BANK_0' has 512 MB; Slot 'BANK_1' has 512 MB"), it states that I have only "512 Megabytes Installed Memory." Is there some BIOS or jumper setting that I should change to accommodate this hardware change? Thank You for your assistance!

    Dear Hoss:

    Thank you very much for the suggestions. Either cleaning the contacts or swapping the DIMMs (or both) did the trick. I now have 1 Gig of useable RAM.

    While I am not certain, the fact that I disconnected all cables from my computer (tower) and re-installed the DIMMs with downward force may have also helped (instead of just pressing them in with sideways pressure as I initially did).

    I would love to update the BIOS on my EP-8K7A+; however, it appears that they may have gone out of business. There are several places on their website that produce a "The page cannot be displayed" error message, including the EP-8K7A+ BIOS updates and links to the EPoX store.

    One question:My motherboard has a jumper called DDR Adjust (2.5V), with adjustments of +0.0V, +0.1V (Default), +0.2V, +0.3V, and +0.4V. Would it help or harm to move the jumper from default to +0.2V? (What is the benefit in the jumper settings)?

    Thank You Very Much

    Richard

The first thing i would suggest it so make sure you have the latest Flash Bios installed on your motherboard.

Just for giggles you could try to reverse the dimms just to make sure one of them isnt bad.

Another thing to try is to take a qtip with alcohol, unplug the computer and attempt to clean the contacts that house the dimm. If it has been in use for years there may be dust buildup.

    Actually before you use the qtip try blowing out the inside with canned air, especially the memory contacts.

Epox ep-8kta3pro want to add ram procedure


That is the correct memory type, max of 1.5GB, and not the 2 you would expect. You can use 64/128/256/512 modules, but when using 512, only 3 are recognized, the 4th slot is disabled.

Graphics card


yes your motherboard can support a 512mb graphics card. most recent 478 motherboards now support that much memory.

Hi.

Most probably yes, if it started happening after you installed new RAM modules. There are to possibilities:
  • one or more of RAM modules is faulty and will need to be replaced or removed
  • the motherboard does not support this layout of the modules which means that you will have to remove 512 MB module
I suggest you remove one of 1 GB memory modules and see if it works. If it does, than put it back and remove the other 1 GB module. If it works again, than motherboard does not support having one 512 MB module and two 1 GB modules at the same time.

My ep-8khal motherboard wont turn on!


first turn off your pc, open the right side panel of your pc and locate the memory card. after locating, pull it out and clean it with a pencil eraser, if you have separate motherboard, clean it also. and then turn your computer on, if the problem goes again, the faulty part might be your computer memory or the separate video card, if you have one.

Note: if you cant' do one of these tips.just have your computer repair by a professional comp. technician.

Good luck!
