I have old lenovo 3000 C300 All-in-one PC. It has

  1. Intel Atom 330 @ 1.66
  2. 2 memory slots, PC2-5300 (667mhz) SODIMM 200 pin memory.
  3. CPU-Z Rated FSB is 531.92 Mhz

Here are results from different scanners -

  1. CPU-Z : i945G PCI Express
  2. Intel chipset utility : 82945G/GZ
  3. Crucial Scanner : Max 2GB RAM
  4. Lenovo Manual : Intel 945GC Express Chipset
  5. Device drivers and Dxdiag didn't reveal anything.

I can't determine whether chipset is whether 945G/GZ/GC/GM. All these chipsets support different memory frequency and size.

945 G/GZ/GM supports 4GB of maximum memory and 945GC supports only 2GB.

If my system supports 4GB, does it mean it requires 2x2GB sticks or 1x4GB stick will work? Is there any memory per slot limit?

Update - I checked on mobo itself, it's 945GC. Also HWiNFO seems more accurate (it showed Intel 945GC (Lakeport-GC) + ICH7).

    Have you tried looking at the mobo itself? There you should find the model imprinted and this could help you to identify if it is a G/GC/GZ/GM mobo - as eg here I945GCS – Zina Feb 12 '16 at 19:36
  • @Zina That's exactly the same mobo. Thanks a ton! – Mark Evans Feb 12 '16 at 20:02
  • Pretty sure the diamondvilles were a single slot and 2gb - in line with MS's standards for netbooks running XP at the time. tomshardware.com/news/Intel-Atom-330-D945GCLF2,6390.html refers to intel's reference design. – Journeyman Geek Feb 13 '16 at 8:57
  • @JourneymanGeek my mobo is different than the one mentioned in article, mine has 2 slots. Can't find anything in speccy/wmic (To be filled by O.E.M). – Mark Evans Feb 13 '16 at 12:01
  • yup. That's curious. Does your graphics card happen to be nvidia? – Journeyman Geek Feb 13 '16 at 12:03

I would trust the proprietary Intel utility, however in this situation your best option is to buy two 2GB sticks and try them both. If it boots and only recognizes 2GB then you have your answer.

  • Added FSB values if it helps identify chipset in anyway. – Mark Evans Feb 12 '16 at 17:04

The maximum supported by your system is 4 GB - Two 2 GB DDR2 667 MHz modules.

Check out this link

  • It's a lenovo PC not IBM. The page you linked also mentions Intel 945GC Chipset which only supports 2GB of memory. – Mark Evans Feb 12 '16 at 17:16
  • Lenovo acquired IBM's personal computer business, so the link will show as IBM Lenovo. That is the correct url – user556070 Feb 12 '16 at 18:49
