The is the master blueprint for DDR4 SDRAM. Whether you are designing a new memory controller, validating a motherboard, or writing low-level firmware, this standard is your ultimate reference.

Whether you are designing a high-speed custom motherboard, writing a DDR4 memory controller in Verilog, or performing deep-level hardware debugging, the JESD79-4D standard provides the absolute mathematical and electrical ground truth for DDR4 architecture. For engineers looking to access or implement this

DDR4 was introduced as a groundbreaking leap in memory technology. Some seven years after launching development of DDR4, JEDEC officially released the new standard (JESD79-4). DDR4 features a per-pin data rate of 1.6 GT/s, with an initial maximum objective of 3.2 GT/s. Building upon the foundational work of DDR3 (JESD79-3) and incorporating aspects of DDR and DDR2 standards (JESD79, JESD79-2), JESD79-4D represents the evolution of these earlier works.

What are mitigations really?

Compared to traditional punishments, cheating players may find it harder to notice mitigations affecting them, increasing the time it takes a cheater to return with a fresh account. Mitigations include, but are not limited to, movement, reach and damage restrictions.

The SaaS Idea

Most checks in Polar are performed by Polar cloud. By moving the load from the customer's server to our cloud, we can ensure stable operations on the server instance.

Polar Cloud

Powered by Advanced Cloud Technology

Our distributed cloud infrastructure enables powerful detection capabilities while maintaining optimal server performance

What is cloud?

Server instances running Polar are connected to the Polar cloud system. Polar sends relevant player packets to the cloud for inspection.

Why cloud?

Detections that do not necessarily require real-time action by Polar are ran in the cloud. This helps reduce CPU and memory load on the server instance.

Why is cloud reliable?

Cloud checks offer higher integrity and stability as they go through an extended processing period to accurately detect suspicious client behaviour.

What about delays?

Since cloud checks do not require real-time game intervention, the detection delay is not interrupting the anticheat operations.

Cloud will only apply mitigations until the anticheat is certain a player is cheating, at which point a punishment is applied.
