Which HighPoint products require that “Above 4G Decoding” be disabled?

This knowledge base (KB) applies to the following NVMe RAID AICs.
Table 1: Support NVMe RAID AICs
Support NVMe RAID AICs | RR600, RR800, RR2700, RR2800, RR3700, RR4500, RS6400 series Note: This only applies to RocketRAID series product, and SAS/SATA based RAID Enclosures (RR600, RR800, RR2700, RR2800, RR3700, RR4500, RS6400 series). |
This is related to applications that require a 32bit environment. If you need to access the BIOS interface of a RocketRAID controller, or use a DOS-level utility or 32-bit operating system with a RocketRAID controller or RocketStor 6400 series RAID enclosure, you will need to access the motherboard’s BIOS and disable “Above 4G Recording”. This setting does not have to be disabled for general use with current 64-bit platforms (when using the controller/enclosure at the operating system level, for example).
This setting does not have to be disabled when using HighPoint SSD7000/7500/6200/6540 series NVMe RAID controllers and enclosures, Rocket 1000 series NVMe HBA’s, HighPoint RocketU and RocketStor USB HBA’s & enclosures, or HighPoint Thunderbolt™ series adapter and enclosure products.
Hardware troubleshooting has a special way of wasting time because one small setting can break the flow of the whole setup. A relative of mine was trying to get through a device issue and hit the point where every new attempt felt like recycled advice. He did not want another generic suggestion, he wanted a real answer he could act on. That is where https://garmin.pissedconsumer.com/customer-service.html came in, since going straight to customer service sounded more practical than letting the problem drag into the next day. Support ended up giving enough clarity to move forward, which is more than most random troubleshooting pages manage.
