Hardware Problem ?

By Adriano.herberth ·
I have a pentium(S) 133MHZ, 8Mb RAM, ChipSet OcTek(OCEAN) with MEGATRENDS BIOS and Hard Disk 4.5Gb. I Use it for internet surfing.
Now i need to upgrade memory to 32Mb RAM. So, i replaced my 8Mb SIMM RAM with 32Mb DIMM RAM.
FIRST time the computercounts again 8Mb RAM, and i could?nt get in to my win95, so i restarted the machine.

SECOND time i receieve an error message like
WHILE INITIALIZING IOS...
WINDOWS PROCTECTING MODE LOCKED THE SYSTEM YOU NEED TO RESTART THE MACHINE

PRESS ANYKEY TO RESTART...

Now, i receive a continuos beep and the machine does stop beeping even if a replace with 8Mb SIMM RAM.

Is it a hardware or software problem, how can i solve this?

One more thought. Re-set your CMOS. Usually there is a jumper on the motherboard to "clear the CMOS". Then try the 8 MB module. If it works, power down, and reset the cmos again, and try the 32 MB module.

like what megtek said, reset your CMOS then put back the 8MB SIMM, it should work then shutdown the power. try to replace this time with your 32MB DIMM, if it hangs again then you have a memory problem.

possibilities:
1. your DIMM is defective
2. if it is PC100, your board doesn't support it cause your board it is using 66MHz and PC100 uses 100MHz frontside bus. so u have incompatibility problem. try to check the coding in the chip on your DIMM if you find "-10" , you most likely acquired a PC100 DIMM. try to replace it with PC66 DIMM.
3. you must configure your CMOS to support DIMM the first time you boot using DIMM module.

hope this helps...

Haven`t really got any brilliantly helpful info but I remember having similar troubles with a PC CHIPS i430TX motherboard. It turned out that the motherboard would only read DIMMS that were double sided and buffered. When I swaped the DIMM module I was having trouble with it worked fine afterwards.
You may have a similar problem.
Hope this insight helps a little.

Many older boards did have dimm slots on the board with simm but the dimm slots were for 4 clock low density sdrams. These sdrams contained chips that only had 2mb max per chip and had to be in sets of 8 to work properly. Many times when inserting newer ram (2 clock and generally without the 8 chip restriction) the mb would exhibit the first and second problem. I think along with the first idea, you may have experienced esd damage or the chipset may have suffered damage via the clock or other component.

Many of the older crossover boards still have restrictions on SIMM configuration. Make sure that you put the 8meg SIMM in the same slot that you took it out of origionaly for the testing.
