FAQ

Can I remove the heatsink/heatspreader?

No. Removing the heatsink/heat spreader will void ZION warranty

How do I determine if my RAM is defective?

Please use a memory testing software to test your memory modules. Memtest86+ or Windows Memory Diagnostic are popular choices.

It would be best if each module is tested individually, in order to produce conclusive results.

If none or all modules produce errors, please contact our tech support with details and we will do our best to help you. (care@zionram.com)

I want to install more memory, in addition to my existing memory kit. What are my options?

We do not recommend mixing memory kits, regardless of brand or model.

By mixing memory kits, there may be compatibility issues such as unable to boot or unable to operate at rated specifications.

Each of our memory kits are thoroughly tested to ensure compatibility within each memory kit. And because we have not tested our memory kit with your existing memory kit, we cannot guarantee compatibility when multiple kits are used.

What is a safe DRAM voltage?

DDR3

Standard DDR3 memory voltage is 1.50V.
Low voltage DDR3 is at 1.35V.
Ultra-low voltage DDR3 is at 1.25V.
When overclocking, DDR3 memory voltage can be set up to 1.65V.

DDR4

Standard DDR4 memory voltage is 1.20V.
When overclocking, DDR4 memory voltage can be set up to 1.35V; or if at DDR4-4133MHz or above, then the rated memory voltage may be up to 1.40V.
In general, voltage above the rated memory kit specifications may damage the memory modules over time. Please also keep in mind that higher voltage means more heat, and excessive heat will shorten the lifespan of the memory modules.

Why is my memory kit only operating at 1333MHz or 1600MHz?

If on an Intel platform, please make sure that XMP is enabled.
If on an AMD platform, please make sure DOCP or XMP-equivalent is enabled.
If XMP or XMP-equivalent does not work as intended or is not available, please manually tweak the BIOS settings for the following four settings according to the information on the warranty sticker or package:

DRAM Frequency
DRAM Voltage
CL Timing (tCL-tRCD-tRP-tRAS)
Command Rate
Make sure to Save and then Quit/Exit!

Does ZION make ECC memory modules?

Yes, we do manufacture ECC memory modules.

What does “CL 9-9-9-24-2N” mean?

CL means “CAS Latency”.

The four numbers represent the values of each type of latency, and are listed as “tCL-tRCD-tRP-tRAS”.

The fifth number represents “Command Rate”, which in this case, has a value of 2. Sometimes, this fifth number may not be listed, but our default setting for the Command Rate value is “2”.

I just installed ZION memory into my system. Why doesn’t it boot?

1) Make sure that your motherboard supports the memory capacity and frequency.

2) Clear the BIOS settings by using the “clear CMOS” jumper/button on the motherboard. Or you may disconnect the power cord and remove the round lithium battery from the motherboard, wait 60 seconds, then put the battery back on the motherboard and reconnect the power cord.

3) Update the motherboard BIOS to the latest version.

4) Check the memory modules with a memory testing software, such as Memtest86+ or Windows Memory Diagnostic.

What is XMP? DOCP?

XMP (Extreme Memory Profile) by Intel is a preprogrammed profile that you can enable in BIOS to set the correct memory settings in one easy step. XMP is exclusive to Intel platforms only.

DOCP is similar to XMP but developed for use on AMD platforms
