JUHOR DDR4 8GB 16GB 3200MHz DIY Desktop Computer Memory Ram

1.This link does not support x99 and x79 series motherboards.2.XMP 2.0 is an optimization technology used by Intel on DDR4,It can automatically overclock. Just open XMP function in the BIOS,So that could get the idealperformance setting.Memory products with a frequency of 3000MHZ and higher than 3000mhz , which are not using the J.E.D.E.C. standard, which are with the X.M.P. standard. Please check whether the motherboard and CPU support X.M.P. before purchasing.3.If the motherboard and CPU don' t support the change standard,the memory will can only work at 2666MHz/2400MHz.In addition, due to the CPU and motherboard’s problems, for 3000MHz and above frequency 3000mhz memory, if you two pieces single channel memory or four combinations together , it may not be able to form a two-channel or multi-channel, without the original manufacture’s test, you can mix and match personally , there may be mismatch and can’t work in right way .4. High-frequency memory runs faster than low-frequency memory. With other hardware support, performance-seeking users can choose high-frequency memory a better experience. However, please note that if two or more memory modules of different frequencies are used simultaneously, the motherboard will automatically synchronize to the lower frequency.For example: When 2400MHz and 2666MHz are used together, the motherboard will automatically run at 2400MHz to achieve operational stability. Therefore considering compatibility and stability, it is recommended to purchase memory with the same frequency as the original memory.NOTICE: We show the photo of the products, pictures for reference only, subject to our available products.Why is my BIOS or diagnostic program (CPU-Z) showing that my memory is running at half the frequency? The BIOS or diagnostic program usually reports the memory bus frequency, which is half of the frequency for DDR type memory. DDR (Double Data Rate) data rate provides twice the memory bus frequency. Therefore, if the memory bus speed is 1600MHz and you are using DDR4-3200 memory, the RAM is running at the correct speed.Please download the latest version of BIOS and other software. If you are using an older version, there may be data discrepancies. If you have any questions, please our online customer service promptly.After-sales service is not provided in the following cases:1. Product appearance damage caused by natural disasters, accidents, force majeure events, or poor storage conditions; 2. Malfunctions not attributable to the product itself due to improper human operation (e.g., use beyond the designed scope, use as fixtures, or for insertion/removal testing) or improper installation (e.g., plugging/unplugging while powered on, powering on without proper installation, or use on equipment incompatible with Jiuhe product specifications);3. IC chip damage, scratches, or detachment;4. PCB circuit board damage, scratches, or fractures;5. Damage or detachment of internal components such as capacitors, resistors, or resistance grids due to external forces; 6. Failure to power on caused by EPROM damage; 7. Damage or alteration of original labels or anti-counterfeiting labels, or unauthorized removal/damage of heat sinks; 8. Memory damage resulting from improper disassembly/assembly, unauthorized repairs, or unauthorized modification of memory SPD parameters.Memory Purchase Tip1. Due to varying factory batches, PCB boards of the same model may differ in color and width. However, all memory products maintain identical quality and compatibility—use them with confidence.2. The manufacturer of the JUHOR memory module does not produce memory chips itself. Depending on the production batch, different chip types (e.g., Samsung, Micron, Hynix, South Asia Yisheng, Elpida), chip counts (4P/8P/16P), or chip orientations (single-sided/double-sided) may be used. Each chip undergoes rigorous testing to ensure compatibility and stability—rest assured when making your purchase.3. After installing memory modules, use CPU-Z to check their actual operating frequency. If the computer fails to operate at the rated frequency, verify the following: whether other hardware supports the purchased frequency; whether multiple memory modules with different frequencies are used together (high-frequency modules automatically synchronize with low-frequency ones); and whether the memory XMP setting is enabled. For further assistance, contact your store's customer service.4. For desktop memory modules exceeding 3000 MHz, they require compatible motherboards and processors to fully utilize their overclocking potential. Before purchasing, verify whether your current motherboard and processor support the desired memory specifications. The BIOS interface displays "XMP" or "DOCP" as the overclocking designation; without XMP enabled, the system operates at the default frequency of 2666 MHz, while enabling XMP via a single click delivers the officially guaranteed overclock speed.5. The rated overclocking frequency is the maximum frequency; do not exceed the product's design limits.6. The transmission speed of dual-channel configuration is nearly twice that of single-channel, delivering significantly better performance. Dual-channel operation requires no additional setup; simply insert the memory modules into the designated slots to enable dual-channel functionality. Generally, a motherboard with two memory slots operates in dual-channel mode when both modules are installed; for motherboards with four or eight slots, dual-channel configuration requires placing both modules in slots of the same color. Specific requirements may vary depending on motherboard design by manufacturer; refer to the official documentation for details.7. For systems with a total installed memory capacity of ≥4 GB, use a 64-bit operating system.8. Regarding insertion marks: To ensure the performance and quality of JUHOR products, all items undergo comprehensive machine testing before shipment, resulting in slight insertion marks on each product's gold fingers. These marks do not affect functionality or after-sales service; please use them with confidence.
