Dell Latitude 7490 RAM & SSD Upgrade Guide (Pakistan)
The Dell Latitude 7490 (8th-gen Kaby Lake R) is one of the most common corporate-lease-return laptops on Pakistan's secondhand market, and it's genuinely upgradeable — two DDR4 SO-DIMM slots supporting a 32GB maximum, plus a single M.2 2280 slot that accepts either SATA or PCIe NVMe SSDs depending on your board revision. It's a thin-chassis ultrabook-style Latitude, though, so unlike the bulkier 5000-series, there's no spare 2.5" bay for a second drive.
This guide covers the exact compatible specs, what a RAM or SSD upgrade costs in Pakistan right now, and the install steps. We're N.N Laptops, Hafeez Center, Lahore — we see a steady stream of 7490 units come through the shop and stock both DDR4 SO-DIMMs and NVMe SSDs.
Max RAM
32GB DDR4-2400 (2× 16GB SO-DIMM, dual-channel — official Dell maximum for this platform)
Max storage
Single M.2 2280 slot supporting SATA or PCIe NVMe SSD — up to 2TB NVMe (no secondary 2.5" bay on this thin-chassis model)
Compatible RAM
DDR4-2400 SO-DIMM, 260-pin, 1.2V
Compatible SSD
M.2 2280, SATA or PCIe NVMe (confirm your board revision supports NVMe before buying — most 7490 units do, but a few early-run boards are SATA-only)
Upgrade cost in Pakistan
- ram
- DDR4 SO-DIMM: 8GB ~Rs 14,000-16,000 · 16GB ~Rs 18,000-32,000 · 32GB single module ~Rs 34,299 (2026 DRAM-shortage pricing — up sharply from 2025 levels; confirm today's price on WhatsApp before ordering).
- ssd
- NVMe M.2 1TB: ~Rs 37,000-56,000 (Gen3 cheaper end, Gen4 higher-speed end) · 2.5" SATA 1TB: ~Rs 25,000-33,000 — both up due to the parallel 2026 NAND shortage.
Step-by-step procedure
- 1
Confirm your current RAM and SSD interface
Task Manager → Performance → Memory shows slots used; Device Manager → Disk drives or CrystalDiskInfo confirms whether your existing M.2 drive is running as SATA or NVMe, which tells you what the slot supports.
- 2
Buy matched DDR4-2400 SO-DIMMs and/or an M.2 NVMe SSD
For the full 32GB, two 16GB modules. WhatsApp 0314 4000131 to confirm today's price and to double-check NVMe compatibility for your specific board revision before ordering.
- 3
Power off, unplug, and ground yourself
Shut down fully, disconnect the charger, and touch an unpainted metal surface before opening the base.
- 4
Remove the base panel
Undo the captive Torx screws around the perimeter and lift the cover from the rear hinge edge to expose the RAM slots and M.2 bay.
- 5
Install the RAM and/or SSD
Seat each SO-DIMM at 45° and press flat until the clips click. Insert the M.2 drive at a slight angle, press flat, and secure the retention screw.
- 6
Reassemble and boot
Replace the panel, reconnect power, and boot. If you replaced the boot drive, restore from a clone or reinstall Windows first.
- 7
Verify in Windows
Settings → System → About for RAM total, Disk Management for SSD capacity. Reseat anything reporting lower than expected.
FAQ
What's the maximum RAM on a Latitude 7490?
32GB DDR4-2400, using two 16GB SO-DIMMs across the two available slots — this is the official maximum for this 8th-gen platform.
Does the 7490 support NVMe SSDs?
Most 7490 units do, since the M.2 2280 slot supports both SATA and PCIe NVMe depending on board revision — but a few early-production boards are SATA-only. Confirm with us on WhatsApp before buying an NVMe drive.
Can I add a second SSD to a Latitude 7490?
No — unlike the bulkier Latitude 5000-series, the 7490's thin chassis has only the single M.2 slot with no spare 2.5" bay for a second drive.
How much does a 32GB RAM upgrade cost in Pakistan right now?
Two 16GB DDR4 SO-DIMMs currently run roughly Rs 36,000-64,000 combined due to the 2026 DRAM shortage, up sharply from 2025 pricing. WhatsApp 0314 4000131 for a confirmed quote.
Can NN Laptops fit the upgrade for me?
Yes — bring your 7490 to Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore. We'll confirm your board's NVMe compatibility, source matched parts, and install while you wait. WhatsApp 0314 4000131 first.
