Downclocking manifests as a slowdown of your training throughput. When a GPU's temperature exceeds a predefined threshold, it will automatically downclock (throttle) to prevent heat damage.
We will be testing liquid cooling in the coming months and update this section accordingly. It is currently unclear whether liquid cooling is worth the increased cost, complexity, and failure rates. Liquid cooling will reduce noise and heat levels. We fully expect RTX 3070 blower cards, but we're less certain about the RTX 3080 and RTX 3090. Here's what they look like:īlower cards are currently facing thermal challenges due to the 3000 series' high power consumption.
Build a PC with two PSUs plugged into two outlets on separate circuits.Are there workarounds to home/office power limitations?
A PSU may have a 1600W rating, but Lambda sees higher rates of PSU failure as workstation power consumption approaches 1500W. Even if your home/office has higher amperage circuits, we recommend against workstations exceeding 1440W. Workstation PSUs beyond this capacity are impractical because they would overload many circuits. The highest rated workstation PSU on the market offers at most 1600W at standard home/office voltages. The GPUs + CPU + motherboard consume 1760W, far beyond the 1440W circuit limit.
National Electrical Code states that circuit load should not exceed 80%.US home/office outlets (NEMA 5-15R) typically supply up to 15 amps at 120V.Your workstation's power draw must not exceed the capacity of its PSU or the circuit it’s plugged into. These GPUs may overload your circuit (or blow your PSU)
The 3000 series GPUs consume far more power than previous generations: Several upcoming RTX 3080 and RTX 3070 models will occupy 2.7 PCIe slots. * OEMs like PNY, ASUS, GIGABYTE, and EVGA will release their own 30XX series GPU models. The RTX 3070 and RTX 3080 are of standard size, similar to the RTX 2080 Ti.
The RTX 3090’s dimensions are quite unorthodox: it occupies 3 PCIe slots and its length will prevent it from fitting into many PC cases. * PCIe extendors introduce structural problems and shouldn't be used if you plan on moving (especially shipping) the workstation.
