Thanks Miyconst! Review: Ram compatibly ## Features - LGA 2011-V3 server socket: Compatible with Intel 5th/6th generation Core i7 processors and XEON E5 V3/V4 series processors, not compatible with LGA 2011 CPUs. (eg Core i7-5820K, Core i7-6850K, Xeon E5-2609 V4, Xeon E5-2673 V3) - DDR4 memory slot: This gaming motherboard is designed with a 4-channel DDR4 memory slot, which supports DDR4 memory with frequencies such as 2133/2400 MHz, supports overclocking, and has a maximum memory capacity of 64GB - Dual M.2 high-speed slots: Including 1 NVME M.2 slot and 1 NGFF M.2 slot. The NGFF M.2 (SATA M.2) slot operates through a SATA channel with a maximum transfer speed of 6Gb/ s, while the NVME M.2 slot operates over a PEIe channel with a maximum transfer speed of 32Gb/s. (NGFF M.2 slot is not compatible with NVME M.2 hard drives, please note the distinction) - PCIe 3.0 protocol standard: 4 PCIE slots include 2 PCIE X16 slots, 1 PCIE X4 slot and 1 PCIE X1 slot. The X99 motherboard supports the PCIe 3.0 protocol. Under this protocol, the transmission rate of the X16 can reach 15.754 GB/s, realizing the release of the performance of the motherboard - Stable performance: X99 computer motherboard is made of 8-layer PCB material, ATX large board design, strong signal anti-interference ability, support sleep mode. And it is equipped with an aluminum alloy heat sink and a high-frequency silent fan to achieve rapid cooling. If the fan does not rotate or rotates slowly, you can use a toothpick or other small objects to move the fan blades and wait for a minute or two for the fan to run normally - One-click "Power On" or "Restart": X99 motherboard is equipped with power-on and restart buttons, which can start the computer with one key without using the case and get rid of cumbersome wiring. It can be used for testing when replacing motherboard accessories and for use in game studios - The package includes: 1*CPU fan bracket, 1*SATA cable, 1*I/O baffle, 1*motherboard. Tip 1: The CR2032 battery on the motherboard has been removed. It is not included in the package. Please purchase it yourself. Tip 2: The user manual is not included in the package.

Please do not wait until the startup LOGO screen appears on the computer screen before operating, because it is already too late. If you don't know where to download the driver, it is recommended to use the win 10 system, which can help you solve all driver problems - Common problem: "FF" code appears on the diagnostic card, which may be caused by incompatible CPU, foreign objects on CPU pins or improper power connection. The metal fingers of the CPU can be wiped with an eraser to ensure cleanliness. If the codes "b7", "b9", "53" and "b0" appear, this is a problem that the motherboard does not detect the memory. You can remove and insert the memory several times or wipe the metal fingers of the memory with an eraser to solve it ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09X1JGMXN | | Available Memory Slots | 4 DDR4 | | Best Sellers Rank | 99,832 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 984 in Motherboards | | Brand | MACHINIST | | Brand Name | MACHINIST | | CPU Model | Xeon | | CPU socket | LGA 2011-3 | | Chipset Type | B85 chip | | Chipset type | B85 chip | | Compatible Devices | Personal Computer | | Compatible Processors | Intel XEON E5 V3, Intel XEON E5 V4, Intel core_i7 | | Compatible devices | Personal Computer | | Compatible processors | Intel XEON E5 V3, Intel XEON E5 V4, Intel core_i7 | | Customer Reviews | 3.6 out of 5 stars 28 Reviews | | Graphics Card Interface | PCI Express | | Item Weight | 1 Kilograms | | Main Power Connector Type | 24-Pin | | Manufacturer | MACHINIST | | Memory Clock Speed | 3200 MHz | | Memory Storage Capacity | 64 GB | | Model Name | MR9A-PRO | | Model Number | X99-MR9A-PRO | | Number of Ethernet Ports | 1 | | Number of Ports | 12 | | Platform | Windows 10 | | Processor Socket | LGA 2011-3 | | RAM Memory Technology | DDR4 | | RAM memory technology | DDR4 | | Ram Memory Maximum Size | 64 GB | | S/PDIF Connector Type | Optical | | System Bus Standard Supported | SATA 3 | | Total PCIe Ports | 4 | | Total SATA Ports | 4 | | Total USB Ports | 6 | | USB 2.0 | 4 | ## Product Details - **Brand:** MACHINIST - **CPU model:** Core i7 - **CPU socket:** LGA 2011-V3 Socket - **Chipset type:** Intel B85 - **Compatible devices:** Personal Computer, Server - **Compatible processors:** core_i7, intel_xeon - **Memory clock speed:** 2 GHz - **Model name:** E5-MR9S - **Platform:** Windows - **RAM memory technology:** DDR4 ## Images ![X99 MR9S MOTHERBOARD - Image 1](https://m.media-amazon.com/images/I/71nVGeBJAgL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: The computer won't power on and the fans don't spin** A: Verify the motherboard power and CPU power connections, confirm CPU and memory model compatibility and condition, and ensure the memory modules are properly seated; if the issue persists after checking these, clear the CMOS **Q: No display (fans spin but keyboard lights remain unresponsive when pressing Caps Lock)** A: Verify the motherboard and CPU power connections, ensure memory modules are properly seated, and confirm CPU/memory model compatibility and condition; if issues persist after these checks, clear CMOS. **Q: No display (fans are spinning and the Caps Lock indicator lights up when pressing Caps Lock)** A: Verify the monitor is on and the display data cable is connected; ensure that the display data cable is connected to the display interface on the graphics card; if the issue persists, clear CMOS. **Q: Press the power button, the fan spins once, then immediately shuts off. Or repeated reboots** A: Clear the CMOS. If the issue persists, check CPU and memory compatibility or damage. If CPU and memory are fine, remove the graphics card, hard drive, and USB devices before attempting to boot again. **Q: Computer blue screen or crash** A: Check if cooling is adequate: Is the CPU cooler fan spinning? Is the cooler base tightly seated against the CPU? Has thermal paste been applied? Check or replace the CPU, memory, hard drive, operating system, and power supply. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It worked!
