I am little bit confused. I have intel 845 chipset mother board which has two slots in it. I want to upgrade my ram. I found that in my mother board ram is DDR and in market DDR2 ram are there which are cheap and easily available. Only thing confusing is that Can I use DDR 2 Ram With my Intel 845 Chipset. If any one knows about it please reply me. Thankx In Advance. :)

Short expert note tied to the thread: asked whether DDR2 can be used on an Intel 845 board and correctly flagged that memory generations differ. The “845” name covers several family members and motherboard designs (some early 845 boards used PC‑SDRAM, others in the 845 family later used DDR); that means the exact board model and its memory controller determine what modules will work. ()

Quick, reliable checks (no guesswork):

  • Look for the board model printed on the PCB (near the PCI/AGP area or I/O cluster) and grab the manual/spec sheet from the vendor site.
  • From Windows, run a system tool such as CPU‑Z to read the Mainboard and SPD tabs (it shows installed module type, part numbers and whether modules are registered/ECC). If you cannot boot Windows, the BIOS/Setup screen often reports the memory type. For an automated compatibility scan, reputable vendors (for example Crucial) offer a System Scanner or lookup by board/model. (www2.cpuid.com)

Practical upgrade options and cautions:

  • If the board accepts DDR (legacy), stay with unbuffered, non‑ECC DDR modules matched by speed/timings; modern DDR2/DDR3 modules are electrically and physically different and are not interchangeable. Mixing registered/ECC modules into a consumer board will often fail. If the goal is DDR2, a platform swap (motherboard/CPU) is required because pin count, notch position and operating voltage differ between generations. (en.wikipedia.org)

Hands‑on tips: power down and unplug before touching modules, use anti‑static precautions, do not force a DIMM into a slot (notches and keying are deliberate). Following ’s point about architecture, the best next step is to identify your exact board model and then buy memory specifically listed for that board.

HI
If the Chipset is set for DDR (DDR1) than DDR wont work,it wont key in to fit. DDR1 is more expensive cos the older the product is the more expensive it becomes, specially when it comes to pc's technology.
DDR2 wont fit on you 845 mobo. when buying RAM also check for the highest speed that your chipset supports witch in youre case is pc133,or you can go with pc100.
cheers

Thnks for your reply but how can i test that my chipset is set for DDR1. Is it possible that It is set for DDR2 also or chipset 845 is old to support DDR2. :)

DRR/DDR2/DDR3 is the physical and logical architecture meaning to begin with physically it wont fit into the slot. youre board might not neccesseraly be old but just older than the DDR2 architecture
