System-specific DDR3 upgrade

This 8 GB kit delivers two 4 GB unbuffered DIMMs built to Dell XPS 8500 X8500-1059BK specifications. It runs at DDR3 1600 (PC3 12800) with CL11 11-11-11 timings at 1.5 V. The modules are non-ECC, single-rank 1Rx8 parts on major-brand chips. Computer Memory Solutions validates compatibility for this exact desktop model.

Ideal for XPS 8500 owners

Owners of the Dell XPS 8500 X8500-1059BK who need a matched pair to populate two of the four slots will benefit from the guaranteed fit. Buyers whose system requires ECC, registered modules, a different pin count, or a voltage other than 1.5 V should look elsewhere. The kit also does not suit platforms limited to DDR3 1333 or lower speeds.

Speed and pin count decide fit

The decisive specification is DDR3 1600 on 240-pin DIMMs at 1.5 V. If the target motherboard accepts PC3 12800 unbuffered non-ECC memory, this kit will work; if it demands a different generation, voltage, or pin layout, it will not.

Questions about this item

Will the 240-pin DDR3 DIMMs fit the four memory slots in my Dell XPS 8500 X8500-1059BK?

Yes, the kit uses standard 240-pin DDR3 DIMMs that match the four slots in the XPS 8500 and the system supports up to 32 GB total.

What is the correct way to seat the two 4 GB modules so the system recognises the full 8 GB at 1600 MHz?

Insert each module firmly until the side clips click; the common mistake is stopping early, which leaves the stick partially seated and the system sees only one module or runs at a lower speed.

Do these non-ECC unbuffered sticks need any firmware updates or periodic replacement?

No firmware is required; the modules run at 1.5 V with CL11 timing and are covered by a limited lifetime warranty from the manufacturer, so no scheduled replacement is needed.
