Upgrading RAM from SIMMs to DIMMs - Advice req.
Posted: Sun May 05, 2002 5:01 pm
Hello friends.
I want to upgrade my RAM without changing mobo.
I want to replace my 2 x 32M EDO SIMMs (60ns) with 1 x 256M or 2 x 128M DIMMs. Chips must comply with the specs below. I may want to put them in a new PC in the future, so I'd like the new RAM to be the most performant, while not crashing my current system (utopia?!)
Specs:
Mobo Mfg : ASUS TX97-XE
BIOS Mfg : Award Modular BIOS v4.51PG
BIOS ID : 11/24/98-82430TX-TX97-XE_C-00
BIOS OEM Signon : #401A0-0112xe-1
Chipset : Intel Triton 430TX rev 1
RAM chips supported:
- 4 x 72pin SIMM FPM/EDO : 4M-8M-16M-32M-64M combinations
-OR-
- 2 x 168pin DIMM SDRAM/EDO : 8M-16M-32M-64M combinations
- Max. RAM = 256M
- DIMMs must be 3.3V, Unbuffered,
- Synchronous DRAM or SDRAM. Max. 24 chips/module.
- SIMM/DIMM mixing not allowed.
I have no clue what chip to get. All I'm sure of is 168-pin DIMMs, the rest is a big ?
- DIMM, RIMM, RDRAM, DDR?
- PC100 or PC133? SDRAM 66MHz, 100MHz, 125MHz or 166MHz?
- "EDO" or not?
- "Buffered" or "Unbuffered" difference important?
- ECC and/or Non-Parity?
- How fast? (ns) Mobo mentions 60ns or 70ns, but would faster chips work anyway?
- On-circuit chips: 32M x 72? 16M x 72? 16M x 64 ?
Any help would be appreciated.
Thanks!
