The Crucial 8GB DDR3L-1600 SODIMM (CT102464BF160B) is a single 8GB, 204-pin laptop memory module rated for DDR3L-1600 (PC3L-12800) at CL11, and it is a sensible upgrade for an older laptop that uses DDR3 or DDR3L and has a free or replaceable SODIMM slot. Because it is a low-voltage 1.35V module that can also run at the standard 1.5V, it suits both DDR3L-only laptops and many older DDR3 machines. The catch is that it only makes sense if your laptop’s chipset can actually address 8GB per slot.

Crucial 8GB DDR3L: key specs at a glance — Crucial 8GB DDR3L key specifications, summarised from the table in this guide.

This guide is for people trying to stretch a few more years out of a Windows laptop from roughly the 2011 to 2015 era, or a similar machine that still has removable RAM. It is based on official platform specifications, published product listings and the JEDEC DDR3 standard as documented publicly, not on hands-on testing. Specs were checked on 17 October 2026.

Short verdict: if your laptop supports DDR3 or DDR3L SODIMMs and 8GB modules, this is a straightforward, no-frills way to get to 8GB or 16GB. If your laptop is a Core 2 Duo-era model or has soldered memory, look elsewhere.

Quick verdict

Best for: older laptops with a DDR3L or DDR3 SODIMM slot that support 8GB modules, such as many Intel 2nd to 4th generation Core laptops
Skip if: your laptop uses DDR4, DDR5 or LPDDR3, has soldered RAM, or is built on an older chipset with an 8GB total limit
Key strengths: dual-voltage DDR3L design (1.35V, can run at 1.5V), standard JEDEC CL11 timings, single 8GB stick that frees up a slot
Key limitations: an ageing DDR3 platform part, no heat spreader, and it will run slower in laptops that only support DDR3-1333 or DDR3-1066

Spec sources: the observed Amazon.in title, Newegg Canada’s listing for part number CT102464BF160B, RS Components and LDLC. Crucial’s own product page could not be reached from our research environment, so rank and component layout are deliberately left out of the table.

DDR3 vs DDR3L: the voltage question that matters most

DDR3L is a low-voltage addendum to the JEDEC DDR3 standard, published in 2010. Standard DDR3 runs at 1.5V, while DDR3L is designed for 1.35V. According to the JEDEC-based summary on Wikipedia’s DDR3 SDRAM page, DDR3L modules are backward compatible with standard DDR3 and can run at 1.5V in an older DDR3 laptop. The reverse is not true: a laptop that explicitly requires DDR3L, such as many mobile 4th generation Intel Core systems, cannot use 1.5V-only DDR3 memory.

This is why a dual-voltage module like the CT102464BF160B is the safer pick for an old laptop. Intel’s specification page for the Core i5-4210U lists only DDR3L and LPDDR3 support, so a 1.5V-only DDR3 stick is the wrong buy for that kind of machine. Meanwhile Intel lists the Core i5-2410M with DDR3 support, and a DDR3L module that can run at 1.5V covers that case too.

One naming trap to avoid: DDR3L is not the same as LPDDR3. LPDDR3 is a separate mobile memory standard that is normally soldered to the motherboard, and it is not compatible with DDR3L SODIMMs. If your laptop’s spec sheet says LPDDR3, there is usually no slot to upgrade at all.

Will your old laptop accept an 8GB stick?

Capacity support is the second big compatibility check, and it depends on the processor or chipset generation rather than on the RAM itself.

Core 2 Duo era (Intel GM45 class): Intel lists a maximum memory size of 8GB total for the Intel 82GM45 graphics and memory controller hub, with DDR3 at 800 and 1066 MT/s. Laptops of this generation were typically designed around smaller modules, so an 8GB stick may not be recognised at all, and even if it is, the platform cannot address more than 8GB in total.
2nd generation Core (Sandy Bridge mobile): Intel lists the Core i5-2410M with a 16GB maximum across two channels and DDR3 at 1066 and 1333. Two 8GB modules fit within that ceiling, but the module will run at the lower speed the platform supports, not 1600.
3rd generation Core (Ivy Bridge mobile): Intel lists the Core i5-3210M with a 32GB maximum and DDR3/DDR3L at 1333 and 1600, so this module is a natural match.
4th generation Core (Haswell mobile U-series): Intel lists the Core i5-4210U with a 16GB maximum and DDR3L 1333/1600, which suits a 1.35V module like this one.

These are processor-level limits. Laptop makers can impose their own lower limits through the BIOS or motherboard design, so always confirm with your laptop’s service manual or with Crucial’s own compatibility tools (the Crucial Advisor and Crucial System Scanner) before ordering.

Speed and latency in practice

DDR3L-1600 with CL11 timings is the standard JEDEC rating for this class of memory, so there is nothing exotic about this module. Its theoretical bandwidth is 12,800 MB/s per module, which is where the PC3-12800 name comes from.

In practice, the bigger gains for an older laptop come from capacity and dual-channel operation rather than from raw speed. Going from 4GB to 8GB, or from 8GB to 16GB, gives a modern browser and Windows more room before they fall back on the much slower storage drive. Installing two modules, one in each slot, lets platforms like the Core i5-2410M and i5-3210M use both of their memory channels, which Intel lists as two on all the processors mentioned above.

If your laptop only supports DDR3-1333 or DDR3-1066, a DDR3-1600 module generally runs at the slower supported speed. That is normal and is not a fault, but it does mean paying for 1600 speed brings no extra benefit on those machines.

Design and build

The CT102464BF160B is a plain SODIMM without a heat spreader, according to the Newegg listing. That is typical for laptop memory, where the module sits under a panel and a heat spreader would add thickness. It is unbuffered and non-ECC, which is exactly what consumer laptops expect. Server-style registered or ECC modules would not be the right choice here.

The part has been on the market for a long time. LDLC records referencing it in May 2012, and RS Components now shows it as no longer stocked. That age is not a quality issue in itself, but it means availability through official channels can be patchy, so buying from a listing sold or fulfilled by a reliable seller matters.

Who should buy it and who should skip it

Crucial 8GB DDR3L: who should buy which — Crucial 8GB DDR3L: who each option suits, summarised from this guide.

Buy it if you have an older laptop with DDR3L or DDR3 SODIMM slots, a platform that supports 8GB modules, and a fast enough storage drive that memory is now the bottleneck. It is especially useful for 3rd and 4th generation Intel Core laptops, where DDR3L-1600 is officially supported.

Skip it if your laptop uses DDR4 or DDR5 (those slots are a different design and this module will not fit), has soldered LPDDR3 memory, or is a Core 2 Duo-era model limited to 8GB total. Also think twice if the laptop still uses a hard disk drive. In an old laptop, moving from a hard disk to an SSD can matter as much as extra RAM, so consider planning both upgrades together.

Alternatives worth comparing

Kingston ValueRAM KVR16LS11/8: Kingston’s datasheet lists an 8GB DDR3L-1600 CL11 204-pin SODIMM with 11-11-11 timings that supports both 1.35V and 1.5V operation, so it is a direct like-for-like alternative.
Crucial 4GB DDR3L-1600 SODIMM (CT51264BF160B): a 4GB DDR3L-1600 CL11 module from the same family, worth considering for laptops that cannot use 8GB per slot.

Whichever brand you pick, match the voltage type (DDR3L if your laptop requires it), the 204-pin SODIMM form factor and a capacity your platform supports.

What to check before you order

Crucial 8GB DDR3L: buying checklist — Crucial 8GB DDR3L: what to check before you buy, from this guide.

Confirm the variant: the Amazon.in listing title we observed reads Crucial 8GB Single DDR3/DDR3L 1600 MT/s (PC3-12800) Unbuffered SODIMM 204-Pin Memory, CT102464BF160B. Make sure the part number on the listing matches before you buy.
Check your laptop’s memory type: run a tool such as CPU-Z or check the label on your existing module for PC3L (DDR3L) or PC3 (DDR3).
Count the slots: many thin laptops have only one slot or some memory soldered to the board.
Mixing modules: if you keep an existing stick, matching capacity and speed gives the best chance of dual-channel operation.
Warranty and service in India: warranty terms depend on the seller and Crucial’s regional policy, so read the warranty details on the listing and keep your invoice.
Static and handling: power off, unplug the charger and, where possible, disconnect the battery before opening the panel.

Frequently asked questions

Will the Crucial CT102464BF160B work in a DDR3 (1.5V) laptop?

Generally yes. DDR3L modules are backward compatible with standard DDR3 and can run at 1.5V, and listings describe this module as dual voltage. Your laptop’s chipset must still support 8GB modules.

Can I use it in a DDR4 laptop?

No. DDR4 laptop memory uses a different SODIMM design with its own notch position and voltage, so this 204-pin DDR3L module will not fit or work in a DDR4 slot.

Is this a single stick or a kit of two?

The listing linked here is for one 8GB module. For 16GB in a two-slot laptop, you need two modules.

Will it run at 1600 MT/s in my laptop?

Only if the platform supports DDR3-1600. Laptops limited to 1333 or 1066, such as the Core i5-2410M generation, generally run it at the lower supported speed.

Can I mix it with my existing 4GB stick?

Often yes, if both are the same type and voltage, though matched pairs are more likely to run in full dual-channel mode. If your laptop requires DDR3L, the old stick must be DDR3L too.

How do I check compatibility before buying?

Use Crucial’s Crucial Advisor or System Scanner, your laptop maker’s service manual, or a utility such as CPU-Z to confirm the memory type, slot count and maximum capacity.

Conclusion

The Crucial 8GB DDR3L-1600 SODIMM is a simple, standards-based upgrade for older laptops with DDR3L or DDR3 slots. Its dual-voltage design is the main reason to pick it over a 1.5V-only DDR3 module, and the 8GB capacity is a real step up for multitasking on an older machine. Check the platform’s capacity limit first, especially on Core 2 Duo-era laptops, and confirm the part number on the listing. Check the current price of the Crucial 8GB DDR3L-1600 SODIMM on Amazon.in.
