G502 X Plus Onboard Memory: What Actually Saves

Yes, the Logitech G502 X Plus has onboard memory for up to five profiles, allowing saved settings to work without G HUB running. It ships with two default profiles; Logitech specifies that G HUB lets you configure all five. Logitech’s G502 X Plus specifications

The catch is what those profiles contain: onboard storage supports core mouse settings and compatible button assignments, but it does not reproduce every feature available in G HUB. If your goal is to keep your sensitivity and everyday shortcuts when moving between computers, the answer is yes. If your goal is to run repeating macros without software, there is a documented limitation.

Five profiles does not mean five DPI settings

A profile is a collection of settings. DPI steps are sensitivity choices within that collection. Changing DPI and switching profiles are separate actions, even though both use colored indicators.

Logitech’s setup guide identifies G9 as the default profile cycling button, while G7 lowers DPI and G8 raises it. The guide also explains the indicator behavior: a DPI change produces a steady color, while a profile change produces a blinking color. That distinction helps you identify whether you changed sensitivity or loaded another configuration. G502 X Plus setup guide, pages 7–9

The two factory profiles are Gaming and Productivity. A useful detail buried in the same guide is that they use different report intervals: 1 ms for Gaming and 2 ms for Productivity, despite sharing a default sensitivity of 1600 DPI. Consequently, matching the DPI alone does not mean two profiles have identical settings.

Seeing only two configurations therefore does not establish that your mouse has a two-profile limit. Logitech’s support page confirms the five-profile capacity after configuration through G HUB and warns that installing G HUB overrides the two default profiles. Record any factory behavior you want to preserve before customizing. Logitech’s onboard profile explanation

Save a profile before closing G HUB

Creating a profile in G HUB and assigning it to onboard storage are separate steps. To make a portable configuration:

1. Connect the G502 X Plus using its LIGHTSPEED receiver or supplied USB cable, then select the mouse in G HUB.
2. With On-Board Memory Mode off, configure the profile you want to keep. Start with your DPI and a simple button assignment that will be easy to check.
3. Open the mouse’s Device Settings using the gear icon and switch On-Board Memory Mode on. Logitech documents this device-settings route, although icon placement can change between software versions. Logitech’s mode instructions
4. Select an onboard slot. Choose Replace With and select your configured profile. An empty slot may instead offer Enable With New.
5. Leave onboard mode enabled, then fully quit G HUB and check the mouse.

The slot menu and its two assignment labels are documented in Logitech’s G HUB manual. Treat the saved slot as a copy: after editing the software profile later, replace the onboard copy again. Logitech G HUB manual, pages 43–45, hosted by Manuals+

For a practical verification, temporarily assign a spare button to an ordinary letter. Open a blank text document, quit G HUB from its tray or menu-bar control, and press that button. Then power the mouse off and on and repeat. Testing on another compatible computer without G HUB provides an additional check that the configuration travels with the mouse.

Closing the application window alone is a weak test because the software may remain running. Verify the saved behavior before uninstalling anything. If you need several onboard profiles, repeat the check for each slot and preserve a profile cycling assignment so you can reach them.

When a macro still needs G HUB

The G502 X Plus having onboard memory does not mean every G HUB macro works without G HUB. Logitech explicitly lists these macro types as unsupported in onboard mode:

• Repeat While Holding
• Toggle
• Sequence
• No Repeat macros containing the documented combinations of text and emojis

Logitech identifies limited No Repeat text and modifier combinations as supported and specifically mentions shortcuts such as Ctrl+C and Ctrl+V. That is narrower than a promise that every macro labeled No Repeat will transfer successfully. Check the actual assignment you need. Logitech’s onboard macro limitations

If sensitivity and a simple keyboard assignment survive closing G HUB, but a repeating macro stops, that result is consistent with the documented restriction. Rewriting the same unsupported macro into another slot will not remove it. Use software mode with G HUB running when you need those macro types.

Likewise, do not equate five stored configurations with automatic game detection. Plan to select onboard profiles manually; application detection is part of the software workflow. For lighting, verify your chosen effect separately instead of assuming that saving DPI proves every LIGHTSYNC setting transferred.

There is no reason to reject the G502 X Plus for ordinary onboard profile storage. It is a suitable buy for saved sensitivity and supported button assignments. Its limitation matters if completely software-free macro automation is the purchase requirement.

Physical suitability still matters when buying the mouse: RTINGS measured a default weight of 103.7 g, while Logitech specifies 106 g. It is a substantial mouse to carry between computers, even though its settings are portable. That measurement comes from RTINGS; this article does not claim hands-on testing.

If even a fresh profile containing only DPI and one simple key assignment will not survive quitting G HUB and power cycling, check the selected slot and write it again. If the same basic configuration fails on another compatible computer, contact Logitech support with the firmware version, G HUB version and exact failed assignment. That evidence warrants diagnosis; an unsupported repeating macro alone does not establish a faulty mouse or justify an RMA.
