Dell Inspiron 580s Upgrade Kit

This 4 GB kit contains two 2 GB DDR3 modules built for the Dell Inspiron 580s desktop. It targets owners who want to increase system memory without mixing speeds or risking incompatibility. The matched pair installs directly into the board’s 240-pin slots and requires no configuration changes.

DDR3 1333 Practical Limits

The DDR3 1333 standard caps data transfer at 10600 MB/s, so the kit cannot exceed that bandwidth regardless of other components. CAS latency is fixed at CL9 with 9-9-9 timings, and voltage is set to 1.5 V, leaving no headroom for manual tuning. Unbuffered, non-ECC operation means the modules work only in consumer desktop chipsets that accept standard DIMMs.

Two-Module Capacity Constraint

Total capacity is limited to 4 GB across the two sticks, so the upgrade suits light office tasks but not memory-intensive workloads. Buyers who need more than 4 GB in this platform must look for higher-density DDR3 modules instead.

Questions about this item

Should I buy the 4 GB kit or look for an 8 GB kit for my Inspiron 580s?

The Inspiron 580s supports up to 8 GB across its four slots, so this 4 GB kit leaves room to add another pair later if you need the maximum capacity.

What does the 1333 MHz rating mean once the modules are installed?

The system will run the memory at 1333 MHz with CL9 timing at 1.5 V, delivering the rated DDR3 10600 bandwidth for everyday desktop tasks.

Will these 240-pin DDR3 DIMMs fit the motherboard in my Inspiron 580s?

Yes, the kit uses standard 240-pin unbuffered DDR3 DIMMs, which match the four memory slots on the Inspiron 580s motherboard.
