DIMM Problem

Postby kbuilta » Wed Jul 25, 2001 8:05

Installed new Kingston 128MB expansion DIMM to my Xpert in slot DIMM2 (Biostar M7VKA v1.0 motherboard - original memory 128MB Infineon in DIMM1). Now I get nothing but beep tones that I recognize to mean memory problems. Tried restoring original DIMM in DIMM1 slot without new memory and same result. M7VKA manual says "don't remove or install DIMMs with JS3-LED1 lighted". Is this the red LED that is next to DIMM3 slot? It is lighted when power is on but of course I had power off when installing DIMMs. Any ideas?

What do you mean with power off??<P>Did you disconnect the power cord or did you just use the front on/off button??<P>The front button is a "soft power off" button.<BR>This means that there's always power on the mainboard.<BR>If you replaced the DIMMS during this soft power off state it could be that the hardware is damaged.<P>Regards.<BR>Data.<BR>

I know I switched power off with the backside on/off switch on the power supply for several of the configuration changes but I could have been a real flathead and just used the front switch for the first, crucial installation, I just don't remember. And certainly I was flatheaded enough to not unplug the unit at all. Geez, you'd think I hadn't worked around electronics for over 20 years or something!<BR>So, now, is it likely I can get my DIMMs tested to see if they are blown like they probably are?

Update to my situation:<BR>I thought maybe the memory was zapped so I bought 256MB new DIMM and handled it VERY CAREFULLY. Put it in and...SAME PROBLEM. It just gives the beep tones. How can this be? Is the M7VKA board so sensitive that the pressure it takes to push a DIMM into a slot can break the traces??<BR>I will try with all the DIMMs I own (now 512MB, wow) and see if anything gets better.

Final result of my DIMM problem: F-S sent a tech to my house who replaced the motherboard because it was faulty. The original memory was good, the first expansion memory I bought was good, but the 256MB memory I bought is no good and now I need to get it replaced but at least I'm up and running and now have twice the RAM I used to have! And it was all under warranty (didn't expect that!). Thanks for all advice and help.

If you have incorrect memory sizes detected, this could also be due to module / chipset compatibility issues.<P>First of all get the newest available BIOS. Sometimes this helps resolving such problems. Your newest FSC BIOS (VCG 0110 FSC <BR>)is here:<BR> <A HREF="http://extranet.fujitsu-siemens.com/support/consumer-public/boards/biostar/m6vcg/m6vcg.zip" TARGET=_blank>http://extranet.fujitsu-siemens.com/support/consumer-public/boards/biostar/m6vcg/m6vcg.zip</A> <P>(can be found easily by going to <A HREF="http://www.fujitsu-siemens.com" TARGET=_blank>www.fujitsu-siemens.com</A> / Service&Support / Consumer PC / Mainboards)<P>If that doesn't help, check the memory requirements of the chipset. There is more to a memory module than just it's size. It has a certain organisation, a certain number of banks, it can be double or single sided (logically, not the way the module is physically organized), buffered/unbuffered aka registered/unregistered.<P>Unfortunately the Biostar Manual (as well as the FSC version) does NOT list the requirements. Especially with high capacity modules (256, 512) chipsets have limitations, for example you may only use modules with a certain logical configuration, or only up to a certain number of banks. Best ask BIOSTAR Tech Support for an EXACT description of what Memory your m6vcg board (with the VIA vt82c694x chipset as far as I know) needs. Ask him for the details I mentioned above.<P>That it works in an other board does not mean your board is defect, or that it must work in your board. If you CAN drive 220Kmh in a porsche but not in your VW beetle does NOT mean your VW is broken ;-)<P>The problem really is that the manual simply states it supports 768MB but it does NOT tell the limitations ...<P>By the way: <A HREF="http://www.kyf.net/supportaz/" TARGET=_blank>http://www.kyf.net/supportaz/</A> <P>is a very good private support page for all FSC consumer PCs - you need marcomedia flash, though.

Have found with the original 128MB dimm that <BR>even though the dimm seemed correctly seated - it was not.<BR>Even though the locking arms appeared closed,<BR>when I shone a bright light on the dimm connector i could see it was not fully down on one side.<BR>I had to push very firmly on the dimm to get it to seat properly. It now works fine.<BR>However the 256MB dimms are still unstable<BR>- any dimm in any slot.<BR>Have had no time to work on this in the meantime. Next move will be bios upgrade.<BR>Then new motherboard.
