Predator Helios 300 PH315-55-795C-HID11

This 15.6 inch QHD gaming laptop runs on an Intel Core i7-12700H processor with 14 cores and 20 threads. It pairs that CPU with an NVIDIA GeForce RTX 3070 Ti graphics card holding 8 GB of GDDR6 memory. The system ships with Windows 11 Home installed and targets users who need high frame rates at 2560 x 1440 resolution.

64 GB DDR5 4800 MHz dual-channel kit installed

The builder replaces the stock memory with two 32 GB modules rated at 4800 MHz, giving 64 GB of total system memory in dual-channel mode. A 1 TB M.2 PCIe 4.0 x4 NVMe SSD provides the primary storage volume. Upgraded thermal interface materials are applied to lower temperatures and reduce fan noise during sustained loads.

240 Hz QHD IPS display with ComfyView

The 15.6 inch panel delivers a 2560 x 1440 resolution at a 240 Hz refresh rate using IPS technology and an anti-glare ComfyView coating. This combination determines whether motion clarity and colour consistency meet the needs of competitive play or colour-sensitive work. The chassis measures 14.10 x 10.90 x 0.98~1.02 inches and weighs 5.73 lbs.

Questions about this item

Will the DDR5 4800MHz memory need replacing later?

The 64 GB DDR5 4800MHz kit uses two 32 GB modules in dual channel. The laptop supports this speed subject to system capability, so further upgrades would only be needed if you exceed the current capacity or platform limits.

Which component hits its limit first during long gaming sessions?

The RTX 3070 Ti runs at a 150 W maximum TGP with a 1510 MHz boost clock. Under sustained load the GPU power ceiling is reached before the CPU 4.7 GHz turbo, making the graphics subsystem the first bottleneck.

How loud and hot does the chassis get when running all day?

HIDevolution applies upgraded thermal interface materials to lower system temperatures, prevent throttling during intensive tasks and minimise fan noise. The 14 core i7-12700H and RTX 3070 Ti 150 W design are tuned for sustained operation.
