Start with a baseline
LIVE RAZER HZ CHECK
This Razer Mouse Polling Rate Test helps you compare what Synapse says with the pointer timing delivered to your browser. It does not read raw USB packets. It gives you a repeatable way to compare 1000Hz, 2000Hz, 4000Hz, and 8000Hz on your own mouse, receiver, browser, and PC.
No download
The browser test starts from the page and needs no account.
Use the same motion
Repeat the same circles before and after a Synapse change.
Judge stability
A short peak is less useful than a strong Low 5% result.
Synapse 4
How to Change Razer Polling Rate in Synapse 4
Razer Mouse Polling Rate Test: change one preset at a time
Razer's current workflow uses Synapse 4. Open the app and select the connected mouse from the dashboard. If the device does not appear, reconnect the cable or receiver and check pairing before changing a setting. A missing device can point to a connection or firmware issue, not a polling-rate issue.
1. Open Synapse 4
Start the app and select the mouse. Confirm that the active product name matches the hardware on your desk.
2. Go to Performance
Open the mouse Performance panel. Razer places the polling control with other sensor and performance settings.
3. Pick a preset
Choose 125Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, or 8000Hz when your model and connection expose that value. Save the profile.
Razer high-rate presets can depend on a compatible HyperPolling Wireless Dongle or a supported wired path. Check Razer's official support information for the model and receiver combination. Do not assume every Razer mouse has every preset.
Before and after
How to Verify a Razer Mouse After Changing Hz
The cleanest check has two runs. First, use the old Synapse preset and save the metrics. Then apply the new preset and run the same test. Keep the browser, USB port, receiver position, surface, and motion the same. This removes many sources of noise from the comparison.
Test before the change
Record average, peak, Low 5%, jitter, stability, and event count.
Use movement that can saturate high rates
Small fast circles or figure-eights create more distinct pointer changes.
Run after the change
Wait for the profile to apply, then use the same sample window.
Read the lower values
Keep a high mode only when Low 5% and stability remain strong.
A browser result can differ from Razer's own utility because each tool watches a different layer. The utility may inspect lower-level device timing. This page watches effective events delivered to the browser. Use both when you need device validation and real-world comparison.
Preset reference
Razer Polling Rate Reference
These intervals explain what each common Razer preset aims to do. They are not a promise that every model, browser, or game will deliver the exact value.
| Preset | Target interval | Useful for | Watch for |
|---|---|---|---|
| 125Hz | 8ms | Office use and battery saving | Large report gap |
| 500Hz | 2ms | Casual play and troubleshooting | Less frequent updates |
| 1000Hz | 1ms | Safe competitive baseline | Higher modes may add little |
| 2000Hz | 0.5ms | High-refresh trial | More CPU and USB work |
| 4000Hz | 0.25ms | Compatible 240Hz+ setups | Frame and wireless stability |
| 8000Hz | 0.125ms | Top-end compatible setup | Receiver, CPU, and game support |
If your Razer Mouse Polling Rate Test shows a strong 1000Hz result and a weak 8000Hz result, the lower preset is the better setting for that connection. The largest advertised value is not automatically the best daily profile.
Troubleshooting
If Razer 4000Hz or 8000Hz Does Not Show
A missing 4K or 8K option usually means that one part of the supported chain is absent. Check the mouse model, firmware, receiver, connection mode, and active profile before you treat it as a software bug.
| Check | Why it matters | Practical action |
|---|---|---|
| Model support | Not every Razer mouse exposes 4K or 8K | Read the official model page |
| HyperPolling receiver | Wireless high rate may need the matching dongle | Pair the supported receiver |
| Firmware | Old firmware can hide modes or affect pairing | Update mouse and dongle |
| USB path | Hubs can add noise or shared load | Use a direct motherboard port |
| Receiver placement | Distance can lower wireless stability | Keep it close to the mouse |
| Movement speed | Slow motion can under-report | Use fast circles for several seconds |
- Keep the HyperPolling receiver within a short, clear distance.
- Avoid placing it beside an active USB 3 hub.
- Close heavy overlays before comparing browser runs.
- Retest with the same browser after a restart.
- Use 1000Hz or 2000Hz if the game stutters at a high preset.

Quick answers
Frequently Asked Questions
How do I change polling rate on a Razer mouse?
Open Razer Synapse 4, select the mouse, open Performance, and choose a supported Polling Rate preset. Available values depend on the model, firmware, and receiver.
Why does Synapse show 8000Hz but the browser shows less?
The browser measures effective pointer event timing. Movement speed, CPU load, receiver distance, USB stability, and browser processing can all lower the observed result.
Do all Razer mice support 4000Hz or 8000Hz?
No. The mouse, firmware, connection mode, and compatible HyperPolling receiver decide which presets appear.
Should I use 8000Hz in every game?
No. Try it in the game you play. If frame time, Low 5%, or aim feel becomes worse, use 1000Hz, 2000Hz, or 4000Hz instead.
Does Synapse need to stay open?
Many devices save core settings to onboard memory, but behavior varies. Test after closing Synapse or restarting if the effective result changes.
When you are ready, run the live Razer Mouse Polling Rate Test and keep the preset that gives the cleanest repeatable result in your actual game.
