Frequently asked questions
Can I use the G.SKILL Ripjaws SODIMM in my desktop PC?
No, you cannot. The G.SKILL Ripjaws uses a SODIMM form factor, which is designed for laptops and compact systems. Your desktop likely requires a UDIMM module. Using the wrong form factor will prevent the memory from fitting into your motherboard slots. Stick to UDIMM options like the Timetec or A-Tech sticks for desktop upgrades.
Does any of these alternatives support ECC?
No, none of the listed alternatives support ECC. All products in this comparison are Non-ECC modules. This means they lack error-correcting code features. This specification is standard for most consumer desktops and laptops. If your system requires ECC, you will need to look for server-grade memory, which is not covered here.
Are all these options 16GB capacity?
Yes, every alternative listed provides exactly 16GB of capacity. This matches the original OWC module size. Each stick offers a single-module upgrade path. You can replace your existing 16GB stick with any of these for a direct swap. This ensures you maintain consistent capacity across different brands.
Is the CAS latency different between the options?
The CAS latency is consistent across most options. The G.SKILL Ripjaws and Timetec desktop modules both operate at CL22. The original OWC UDIMM also targets similar performance tiers. While timings can vary, these specific 3200MHz models share the CL22 specification. This ensures comparable response times for general tasks.
Which option is best for a laptop upgrade?
The G.SKILL Ripjaws SODIMM and the Timetec SODIMM are the best choices for laptops. Both use the SODIMM form factor required by portable computers. The G.SKILL model is noted for dual-channel stability if you buy two sticks. The Timetec option offers a straightforward single-stick boost. Avoid the UDIMM desktop modules, as they will not fit.
Do these modules run at 1.2V?
Yes, these DDR4 modules run at the standard 1.2V voltage. The Timetec desktop and SODIMM options explicitly list 1.2V. This is the standard voltage for DDR4 memory. It ensures compatibility with modern motherboards and laptops. You do not need to adjust BIOS settings for voltage to match the original OWC specification.
Can I mix different brands in dual-channel mode?
It is not recommended to mix brands for dual-channel performance. While the Timetec SODIMM and G.SKILL SODIMM share specs, mixing them can cause stability issues. For best results, buy matched kits from the same manufacturer. The G.SKILL Ripjaws is marketed as a solid upgrade for users wanting matched sticks for stability.
Is the OWC SODIMM suitable for desktops?
No, the OWC SODIMM is not suitable for standard desktops. It uses the SODIMM form factor, which is too small for desktop motherboard slots. This module is designed specifically for laptops and compact PCs. If you are upgrading a desktop tower, you must choose a UDIMM module like the original OWC desktop stick or the Timetec alternative.
