NVRAM

By coyotech ·
I'm upgrading some celeron systems for an organization. I don't have any manuals for these machines, but they are mainly 300-350 celerons on what I believe is an Intel board. My question is this: they all have 168 pin PC100 NVRAM. I tried replacing the NVRAM with 128 mgs PC100 SDRAM, and found the system wouldn't boot--or at least the screen was black. No beeps. I took the SDRAM out and put the NVRAM back in and it booted up normally. I've never run into NVRAM before. Tomorrow I'll get better information on the motherboard and bios, but has anyone run into PC's that run only NVRAM? Is this usual for Celerons? There is only one jumper on this board, which probably isn't for RAM, but I haven't checked out the bios settings yet to see if there's a switch for RAM types.
If you have seen this sort of system, I'd like some information on the best way to upgrade them. Replacing the chip and board is out for now, since both the organization and myself are non-profit and low-budget for now :-)

NVRAM

by zlitocook In reply to NVRAM

Non-Volatile Random Access Memory, a type of memory that retains its contents when power is turned off. One type of NVRAM is SRAM that is made non-volatile by connecting it to a constant power source such as a battery.
Short for Synchronous DRAM, a new type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus in many newer computers

You need to go to the main board site and see what it supports. It's probley 66mhznot 100 mhz.

Are you SURE those are NVRAM? I've never heard of any Celeron-based system using NVRAM before. How did you know those are NVRAM? Who made those? What are the markings on the chips on the NVRAM DIMM?

Celerons are PC66, but should work fine with PC100 or faster SDRAM. I have a Celeron 400 running with both PC100 and PC133 SDRAM.
