1.All 3200MHz 1.2V memory modules use green PCB boards.
2.The 3200MHz 1.35V memory module randomly sends a green or black PCB board, and does not accept specified PCB board colors.
3.Please pay attention to identification before purchasing the product. If you have any questions, please feel free to contact our online customer service.

Note:
1it can't fit for x99 and x79 series motherboard please check it before placing order,thanks.

2.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.
If the motherboard and CPU don’t support the change standard, the memory will can only work at 2666MHz/2400MHz.

3.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.We make sure all the rams been tested 100% before shipping,if tried every method we offer you still can not solve your
problems,we may have to do replacement.items need to be sent back by local post office air mail(not accept DHL/FEDEX/UPS/TNT,ect) ,when tracking number online,we will send you new ones. All returned items must be in the original packaging and condition，please understanding.

Because the memory controller of the AMD platform is generally weak, it will be more unstable than the memory of the Intel platform when using high-frequency memory.
We recommend using 6000MHz RAM on the AMD am5 platform to avoid the problem that EXPO will not run properly.
If you are an AMD CPU, please choose 6000MHz or 6400MHz (Hynix A die), otherwise the product may not function properly and the frequency may need to be reduced. To avoid causing you losses, please choose the correct option! Thank you for your understanding!

If you are a DDR5 motherboard, we only recommend that you use 2 RAM.
If you want to use 4 RAM at the same time, your frequency may be reduced.

Intel CPU:When you use four DDR5 memory at the same time, the default frequency of the system will become 4000, and the maximum can only reach 5600MHz.

AMD CPU:When you use four DDR5 memory at the same time, the default frequency of the system will become 3600, and the maximum can only reach 4800MHz.

In addition, due to the CPU and motherboard’s problems, if you use two pieces single channel ram or four combinations together , it can’t form two-channel or multi-channel, without the original manufacture’s test, you can’t mix and match personally , there may be mismatch and can’t work in right way, please noted, thanks .

We are not responsible for any wrong or undeliverable address. Please make sure your address is correct and detailed before placing an order.

Please make sure the item is compatible with your model before ordering. Before ordering, please make sure that the RAM is compatible with the motherboard/CPU.

DDR4 and DDR5 memory are not compatible, and DDR5 memory modules cannot be used on motherboards that support DDR4,
This memory module is used for Desktop and does not support Laptop

CUSU Black Heatsink DDR5 gaming memory can run up to 6000MT/s. Each 288-pin DIMM is equipped with PMIC (Power Management IC) and ECC (Error Correcting Code), featuring a more stable performance and high-speed operation. Armored with aluminum alloy heatsink, the memory modules function with better heat dissipation. With selected originally produced IC and other parts, they have undergone rigorous tests on compatibility, reliability and overall performance.
