Newbie question: PC100 RAM - can my PC only use this?
Hi there,
As you can tell from the subject line, I'm not so bright about hardware! I want to add RAM to my PC and I've seen some good deals on ebay - but I'm not sure what to buy. I recently bought 64MB SDRAM PC100 - purely because that was the exact description of the 64MB that came with my PC when I bought it. I put it in and it went OK - I really notice the vast improvement it's made to the performance. Now I want to have 256mb installed (as opposed to the 128MB currently installed) but the choices of RAM of the type 'PC100' aren't so plentiful. I've seen a lot of PC133 but I don't know if my PC can use it. I use AIDA32 to monitor my system and it gave me the following information. Can someone please tell me if I can use PC133 or can I only look for PC100? Thanks, I could really appreciate some help, Joanna INFO: Operating System: Microsoft Windows 98 SE 4.10.2222A (Win98 SE) Processor Properties: Manufacturer GenuineIntel Version Celeron External Clock 66 MHz Maximum Clock 433 MHz Current Clock 433 MHz Type Central Processor Status Enabled Socket Designation J1 [ Memory Devices / DIMM1 ] Memory Device Properties: Form Factor DIMM Type DRAM Type Detail Synchronous Size 64 MB Speed 100 MHz Total Width 64-bit Data Width 64-bit Device Locator DIMM1 [ Memory Devices / DIMM2 ] Memory Device Properties: Form Factor DIMM Type DRAM Type Detail Synchronous Size 64 MB Speed 83 MHz Total Width 64-bit Data Width 64-bit Device Locator DIMM2 [ SPD ]: [ Infineon HYS64V8300GU-8 ] Memory Module Properties: Module Name Infineon HYS64V8300GU-8 Serial Number 250DE81Ch Module Size 64 MB (1 rows, 4 banks) Module Type Unbuffered Memory Type SDRAM Memory Speed PC100 (100 MHz) Module Width 64 bit Module Voltage LVTTL Error Detection Method None Refresh Rate Normal (15.625 us), Self-Refresh Highest CAS Latency 3.0 (10.0 ns @ 100 MHz) 2nd Highest CAS Latency 2.0 (10.0 ns @ 100 MHz) Memory Module Features: Early RAS# Precharge Not Supported Auto-Precharge Supported Precharge All Supported Write1/Read Burst Supported Buffered Address/Control Inputs Not Supported Registered Address/Control Inputs Not Supported On-Card PLL (Clock) Not Supported Buffered DQMB Inputs Not Supported Registered DQMB Inputs Not Supported Differential Clock Input Not Supported Redundant Row Address Not Supported [ CHIPSET ]: Chipset Properties: Motherboard Chipset Intel Whitney i810-DC100 In-Order Queue Depth 4 CAS Latency 3T RAS To CAS Delay 2T RAS Precharge 2T RAS Active Time 5T Integrated Graphics Controller: Graphics Controller Type Intel i752 Graphics Controller Status Enabled Shared Memory Size 1 MB Memory Slots: DRAM Slot #1 64 MB (SDRAM) DRAM Slot #2 64 MB (SDRAM) [ MEMORY ]: Physical Memory: Total 126 MB Used 124 MB Free 1 MB Utilization 99 % Swap Space: Total 1921 MB Used 130 MB Free 1791 MB Utilization 7 % Virtual Memory: Total 2047 MB Used 255 MB Free 1792 MB Utilization 12 % |

I use PC133 SDRAM on machines that call for PC100 as it's backwards
compatible. So it should work just fine. On Wed, 24 Dec 2003 19:53:54 -0000, "Joanna" wrote: Hi there, As you can tell from the subject line, I'm not so bright about hardware!

Not necessarily true, most PC133 in the market now is high-density, while most boards that were spec'd, use PC100, can only accept low-density. PC100 in 256MB module(s) would be the preferred upgrade, but those are also becoming less common, it may be easiest to buy 2, 128MB PC100 modules, if the goal is only 256MB. |
