Check if your CPU is compatible with your motherboard by looking at the specifications and ensuring they match.

unfortunately this outcome stems from the long lifespan of CPU sockets. the motherboard came out before the full hardware development, so once released everything functions properly. manufacturers often avoid updating BIOS to support certain CPUs or may not release public changes. with an Intel 945 chipset, it seems reasonable to expect compatibility with 2x2GB drives, though we can't be entirely sure since HP only confirmed 2GB. it's likely it will work.
On 775? That’s unlikely unless you opt for a C2Q. Even then, it’s wiser to skip it entirely. 1156 offers comparable pricing to 775 but supports much higher capacity DDR3. The BCLK speed isn’t as restrictive—1400 MHz DDR3 suffices for 500 FSB, and most 2 GB modules perform well at that rate. In contrast, 775’s limitations become apparent with higher speeds. Switching to 1156 or 1366 is a smart move; you won’t need ridiculously fast RAM when you have capable CPUs. This advice comes from someone who owns an OCS 775 for fun, appreciating its performance despite the clock challenges. While it’s tough to find it today, the benefits are clear. CPUs will handle much more efficiently at those speeds.
In Canada I’m on a tight budget, so I’ll switch from the Pentium e2140 to a 2 duo e4400 with 4GB RAM.
The power supply is solid, so upgrades are definitely possible. The board CPU and RAM might be worth selling for around 20 to 30 dollars. I recommend checking used LGA 1156 or LGA 1155 parts on sites like classifieds, FB Marketplace, or Gumtree in Canada. You could also explore e-waste recycling centers or do some dumpster diving to spot decent workstation components such as X58 or X79 models being discarded.
