Intel LGA 1700 platform board

This ATX motherboard pairs the Intel Z790 Express chipset with an LGA 1700 socket that supports 13th and 14th generation processors. Four DDR5 DIMM slots accept up to 192 GB of memory with XMP 3.0 profiles. It targets builders who need high core counts, fast storage lanes and modern wireless connectivity in a single chassis.

VRM Thermal Armor Advanced and M.2 Thermal Guard

A twin 16+1+2 phase digital VRM solution feeds the CPU while heatsinks cover the power stages and M.2 slots. Smart Fan 6 controls curve points based on onboard sensors to keep component temperatures in check during sustained loads. The 2.5 GbE LAN and Wi-Fi 6E controllers run without active cooling.

Four PCIe 4.0 x4 M.2 slots

One CPU-attached slot and three chipset-attached slots each deliver four lanes of PCIe 4.0 bandwidth for 2280 or 22110 solid-state drives. This density lets the platform serve as a primary workstation drive array or a compact gaming library without sacrificing the PCIe 5.0 x16 graphics slot.

Questions about this item

How do I use the Q-Flash Plus button to update the BIOS without a CPU installed?

With the 24-pin and 8-pin power cables connected, insert a USB drive containing the renamed BIOS file into the dedicated Q-Flash Plus USB port, then press the Q-Flash Plus button; the LED will flash during the update and stay solid when finished.

Which thermal pads on the M.2 Thermal Guard need replacing if SSD temperatures rise after a year?

The pre-applied pads on the M.2 heatsinks covering the four PCIe 4.0 x4 slots (M2A_CPU, M2P_SB, M2Q_SB and the fourth slot) can be peeled off and replaced with 1 mm pads of similar conductivity.

At what memory speed does the DDR5 voltage regulator hit its thermal limit first during a long stress test?

The 16+1+2 phase digital VRM is rated for the full supported range up to DDR5 8266 (O.C.), so the CPU or memory ICs typically throttle before the VRM reaches its thermal ceiling.
