Frequently Asked Questions
Is this module compatible with DDR3 or DDR4 motherboard slots?
No. DDR2 memory is keyed differently with 240 pins specific to DDR2 sockets and will not physically fit or operate in DDR, DDR3, or DDR4 motherboards.
Does this memory support ECC error correction?
No. This is standard unbuffered, non-ECC desktop RAM intended for client PCs rather than enterprise server platforms requiring ECC.
Why buy individual memory modules here instead of an assorted bulk lot?
Buying individually lets you match an exact part number and specification for your system without paying for extra incompatible sticks from a mixed lot. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, qualify for free shipping at $28 or more, and leave our Idaho warehouse the same or next business day.
Legacy desktop hardware does not ask for modern flash; it just demands the exact timing and pinout it was wired for. Snap this stick into the slot, listen for the POST beep, and let the old machine get right back to business.
