New PC build - RAM recommendations?

So, I’m looking at a relatively new Computer I picked up just a few days ago. Here are the specs as reported by Speccy:

Operating System

Windows 10 Pro 32-bit
Main Processor
Intel Pentium G3430 @ 3.30 GHz 31 ° C Haswell 22
Haswell 22nm technology
Memory
8,00GB dual-channel DDR3 @ 666MHz (9-9-9-24)
Motherboard
MSI H81M-P33 (MS-7817) (SOCKET 0) 28 °C
Graphics
Belinea101711 (1280x1024@60Hz)
Intel HD Graphics (MSI)
Storage
465GB Toshiba DT01ACA050 (SATA) 37 °C
Optical Drives
TSSTcorp CDDVDW SH-224FB
Audio
Realtek High Definition

I wanted to ask about the memory, specifically based on these details here:

Memory

Memory Slots
Total Memory Slots 4
Used Memory Slots 2
Free Memory Slots 2

Memory Details

Type DDR3
Size 8192 MB
Channels Dual
DRAM Frequency 666.5 MHz
CAS Latency (CL) 9 cycles
Row Address Strobe (tRCD) 9 cycles
prefetch ras # (tRP) 9 cycles
RAS Cycle Time (tRAS) 24 cycles
Command Rate (CR) 1T

A couple of questions:

- Can I easily upgrade this machine with an additional 8 GB of RAM, and will I actually notice any general speed improvements—even though I'm currently running 32-bit Windows?

- I'm a little unsure about those free slots... how much can I actually trust Speccy to be accurate with this kind of information?

Thanks for the help!

8 GB of RAM is plenty for what you need, and honestly, throwing more memory at this thing isn't going to change a thing. If you actually want a faster Computer, you need to step up your processor and graphics card.

Hold up, you're running 32-bit Windows with 8GB of RAM? If you check your Computer, you'll probably see you aren't even using more than 3-something GB right now. It's kind of a waste, honestly. You should definitely switch to 64-bit Windows so you can actually use all 8GB. Upgrading to 16GB won't really speed things up unless you're running a ton of heavy programs at once, like VMs or Photoshop and stuff.

The biggest boost would probably come from grabbing an SSD. Stick the OS and your main apps on there. You can find a 120GB one for about $100 or maybe a 250GB for $167 or even more

Also, regarding the Speccy info and the slots—if you look at the picture of your motherboard, you'll see it only has two slots, even though Speccy claims there are four:

Wait... there isn't even a dedicated GPU listed in the thread? It’s just running on integrated graphics?

Yeah, at least according to these specs

Thanks so much for all the input, everyone. So, it sounds like I need to switch over to 64-bit Windows—and if that’s the case, then I guess that's the fix. Man, back to square one for me... 😵

Yeah, well—you basically have to tear it all down and start from scratch 😁 but hey, at least now you know that 32-bit versions of Windows can only really handle up to 3.5GB of RAM 😁
