DDR3 RDIMM
DDR3 servers such as the PowerEdge R710, R720 and T620 still run accounting systems, phone servers and file shares in plenty of businesses. Memory for them is cheap and plentiful on the secondary market, which makes a targeted upgrade a reasonable bridge while you plan a refresh.
We handle DDR3 as a maintenance item, not a growth path. Every upgrade comes with a written migration plan so the hardware does not become the reason a business stalls.

What RackLedge does
- Tested refurbished modules with burn-in before install
- Low-voltage vs standard-voltage matching on 12G platforms
- Migration plan: physical-to-virtual or lift to a current PowerEdge
- Data protection during the stopgap period (backups verified first)
How we work
A memory engagement starts with evidence, not a parts list. We pull utilization from your monitoring or hypervisor, confirm memory is the real constraint, and only then choose modules that keep every channel populated at full speed.
Firmware comes first. BIOS and BMC updates fix memory training bugs and unlock newer module types, so we baseline them before opening the chassis. Installation is scheduled in a maintenance window and validated with a memory test and an application check before the server goes back into rotation.
Parts are new or tested refurbished with a warranty, matched to the vendor's qualified list or an equivalent specification, and we keep a record of exactly what went where so the next upgrade starts from documentation rather than guesswork.

Frequently asked questions
Is it worth upgrading a DDR3 server at all?
Only as a bridge. If the box is the single copy of a critical application, put the money into a backup and a migration instead.
Can DDR3 and DDR3L be mixed?
On most 12G systems the server will run everything at 1.5 V, which works but negates the low-voltage benefit. Keep them consistent when you can.
