Pros & Cons

Pros

  • ✓ Genuine SK Hynix part, not a relabeled bulk pull
  • ✓ Exact part number HMT351S6CFR8C-PB printed for QVL matching
  • ✓ PC3-12800 (DDR3-1600) speed grade, top of the mainstream DDR3 range
  • ✓ Ships within 24 hours outside holidays and weekends

Cons

  • ✗ Single 4GB module only, so dual-channel needs a second purchase
  • ✗ Non-ECC, so it will not work in ECC-required servers or workstations
  • ✗ 4GB per module caps total capacity on two-slot boards at 8GB
  • ✗ DDR3 is end-of-life, so no upgrade path to a newer platform

Manufacturer description

The SK Hynix HMT351S6CFR8C-PB is a genuine 4GB DDR3 SODIMM-class module rated at PC3-12800 (DDR3-1600), built for non-ECC unbuffered systems that need matched, first-party memory rather than a rebranded pull. Because it ships as a single 4GB module, it drops cleanly into a one-slot upgrade or pairs with an identical stick for dual-channel operation on older laptops and DDR3-era desktops where mismatched timings cause boot failures. The value here is provenance: the part number HMT351S6CFR8C-PB is printed on the label, so you can verify the die and organization against your board's QVL before…

SpecPicks Verdict

SpecPicks scored Hynix 4GB PC3-12800 DDR3 1600MHz Non-ECC Unbuffered HMT351S6CFR8C-PB using a rating × review-volume × price-fit model applied to published specs and reviews across the memory & ram category. SK Hynix's memory & ram lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for memory & ram of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Is this real SK Hynix memory or a third-party relabel?

It is listed as guaranteed genuine Hynix under part number HMT351S6CFR8C-PB, the manufacturer's own designation rather than a reseller SKU.

Will this work in my ECC server?

No. This is a non-ECC unbuffered module. Systems that require ECC registered or ECC unbuffered memory will not accept it.

Can I run two of these in dual-channel?

The listing covers one 4GB module. For dual-channel you need a second identical HMT351S6CFR8C-PB stick, matching part numbers to avoid timing mismatches.

What speed does it run at?

DDR3 SDRAM at PC3-12800, which is DDR3-1600. It will also downclock to slower DDR3 speeds if your board or CPU memory controller tops out lower.

How quickly does it ship and what if it is defective?

The seller states shipping within 24 hours except holidays and weekends. Check the product listing for current warranty and return terms, which are not specified in the product data.
