HP OMEN 35L Gaming Desktop GT16-0066m: problems, parts and running costs

Checked: 2026-11-01

Summary

This black mid-tower desktop with a Ryzen 7 8700G and RTX 4060 8GB is a 1080p gaming machine; owners report memory instability with four DIMMs and occasional boot issues. Running costs average about $75.92 per year for typical gaming use, and the system is a good buy below $1,100.

Common problems and fixes

Memory EXPO instability with four DIMMs — owners of closely related GT16-0044 systems report that enabling EXPO or filling all four DDR5 slots can prevent boot; usable speeds often fall to 3600MT/s or lower. Fix by using a matched 2×16GB kit and disabling EXPO in BIOS, or resetting CMOS. HP documents this behavior under Modern Standby with memory Turbo enabled. [1][2]
Occasional boot or POST issues — some owners report getting stuck at the boot logo or seeing intermittent POST failures, often resolved by checking storage/RAM with HP UEFI diagnostics or resetting CMOS. HP does not list this as a widespread defect. [1]
CPU upgrade limitations — HP’s Wolant 8CF4 motherboard officially supports only 65W Ryzen 8000G processors (8700G, 8600G, 8500G); users attempting 9700X or newer chips report intermittent boot failures. Verify BIOS and power limits before upgrading. [1]

Parts and consumables

Memory — stock 2×8GB Kingston FURY DDR5 RGB; optional upgrade to 2×16GB DDR5 UDIMM kit. No scheduled annual replacement. [1]
Second SSD — motherboard has an extra M.2 PCIe NVMe slot; example WD_BLACK SN770 1TB at Best Buy was listed $99.99 but sold out. Verify drive length and heatsink clearance before purchase. [1]
CPU — installed Ryzen 7 8700G; HP lists 8600G and 8500G as compatible upgrades. No annual replacement required. [1]
Graphics card — preinstalled RTX 4060 8GB; PCIe x16 slot available. No annual replacement required. [1]
Cooling and PSU — 120mm 4-heatpipe RGB air cooler and 600W 80 Plus Gold ATX PSU. No scheduled replacement. [1]
Accessories — no proprietary toner, filters or cartridges; display, keyboard, mouse and HDMI/DP cables not documented as included. [1]

Yearly running cost

Typical gaming scenario: 4 hours of gaming per day at 200W wall draw, plus 4 hours of idle at 60W, electricity $0.20/kWh. Annual energy: 0.20kW × 4 × 365 = 292kWh for gaming, plus 87.6kWh for idle. Annual cost: $58.40 + $17.52 = $75.92. At 2 hours of gaming per day: 146kWh, or $29.20 per year, excluding idle. Actual cost varies with games, frame rate caps, lighting and power efficiency. No mandatory software subscriptions for normal Windows gaming or local media. [1]

When it is a good buy

≤$900 — excellent value for a new, warranted RTX 4060 desktop in this chassis. [1]
$901–$1,099 — reasonable if you want the OMEN case and HP support. [1]
$1,100–$1,299 — weak value unless you plan to add memory or a graphics card. [1]
$1,300–$1,649.99 — poor value compared with CyberPowerPC Core Ultra 7 265F / RTX 5060 Ti 8GB at $1,439.99 and Core Ultra 7 265F / RTX 5070 12GB at $1,649.99, which offer stronger GPUs. [1]
Above $1,649.99 — gaming performance alone does not justify the price; consider CyberPowerPC or Skytech alternatives with RTX 5060 Ti or 5070. [1]
