Server DDR1 Memory Kit

This 4 GB kit contains two 2 GB 184-pin DDR1 modules rated at 333 MHz PC2700 with CL2.5 timing. Each stick is ECC registered and operates at 2.5 V using major-brand chips without heat spreaders. It is built specifically for Sun Fire V215, V245, V240 and V445 servers.

Suited for legacy Sun Fire maintenance

The kit fits administrators replacing or expanding memory in the listed Sun Fire models where the platform maximum is 16 GB across eight sockets. Buyers needing higher capacity per module or non-ECC unbuffered memory for other platforms should look elsewhere.

ECC registered DDR1 at 333 MHz

The registered ECC design with 2Rx4 organisation is the single specification that determines compatibility. Only systems requiring PC2700 registered DIMMs at this voltage and pin count will accept the kit.

Questions about this item

Which Sun server models must I already own for this 184-pin DDR1 333MHz ECC registered kit to be compatible?

This kit is validated for Sun Fire V215, V245, V240 and V445 servers.

Can I add this 2Rx4 registered DDR1 kit alongside existing unbuffered DDR1 modules in the same Sun Fire system?

Registered and unbuffered DDR1 modules cannot be mixed on the same memory bus; all slots must use registered DIMMs.

How do I verify the 2.5V 184-pin DDR1 modules are running at PC2700 333MHz with ECC active after installation?

Check the system BIOS or firmware memory report for 333MHz speed, registered mode and ECC enabled status.
