memory errors

[stevep12]

I am wondering if someone may be able to help me with a memory error problem I am having.
I have an FIC AZ-11 mobo with 3 128MB SDRAM chips. Im sure they are all PC133 chips, but one doesnt say anything to determine this.
I have Norton Systemworks on my computer. When I run a hardware diagnostic on the memory there is an error at location 225132544.
What I did was take all the chips out and try them one at a time in all three slots to see which one was the problem. I found no problems this way.
Next I did another set of tests using pairs of RAM in different combinations but with no errors.
As soon as I put all 3 chips in, I get the error.
Does this mean the problem is my mobo or that the chips are incompatible in some way?
Is there any other tests I can do?
How can I tell what speed the 3 chips are running at?
Thanks for any help.

PS: I just read in a different post about Samsung memory chips causing Norton Systemworks to give memory error indication.
I wrote down a note that one of my DIMMs has Samsung chips on it.

I have often seen Norton Systemworks detect memory errors on perfectly viable chips.

The problem that you have encountered is that the memory diagnostic in the utilities package nearly <i>always</i> detects a memory error with more than 256MB of RAM installed.

I don't have the link right at my fingertips (surprisingly enough!) but if you search the Web, eventually you'll find a reference to it. It was posted a while back. I think I saw it the other day while checking out memory prices, either at Crucial or Kingston.

If you are using Windows95/98/98SE/ME, here is the supposed fix (no guarantees ... don't kill the messenger!)

<font color=purple>"Click Start and choose Run. The Run dialog box appears.
Type: SYSEDIT and click OK.
Click the SYSTEM.INI title bar to display the file.
Choose the Search menu and click Find.
Type: VCACHE and click Next.
When you find the [vcache] section, add the MinFileCache= and MaxFileCache= lines to it, as shown below, (if there is no [vcache] section, create it). These settings limit the size of the disk cache file to between 5 and 8 MB. This should be acceptable for nearly all systems, regardless of the size of the hard drive and the amount of RAM.

[vcache]
MinFileCache=5120
MaxFileCache=8192


Choose the File menu, and click Save.
Close the System Configuration Editor.
Restart the computer."</font color=purple>

If you are running Win2K or WinXP ... just don't use the memory diagnostic anymore!


Try this program for a decent memory test:

You should be able to look in the BIOS and ascertain your current memory speed. Check your mainboard manual for the correct settings. Here's the support <A HREF="http://www.fica.com/products/motherboard/Socket462/AZ11.stm" target="_new">page</A>.
