Intel Adds Optane Memory Support for Pentium and Celeron Processors

Intel's Optane technology brings all the heady promises of a new memory technology, like blazing fast speeds and incredible endurance, but pricing and limited compatibility with existing systems have hampered wider adoption. This holds true especially for Intel's Optane Memory solution, which is a small drive used for caching hard drives to boost overall performance. Intel has long restricted compatibility for the speedy solution by only enabling support on certain chips, like Core i7, i5, and i3 models while disabling support for the value-oriented Pentium and Celeron line of chips.

Now, with absolutely no fanfare, Intel has enabled Optane support for the cheap Pentium and Celeron chips via a new memory user interface and driver update. Support for these lower-end chips does come with a few caveats, though, as you'll need a 8th-gen (or higher) processor and RST driver 17.2, or later.

Intel enables Optane Memory on cheaper motherboards, like those with the H370 and B360 chipset, along with the expected support for higher-end boards, like the Z370 and Z390 models (although we wouldn't expect those premium boards to be paired with a Pentium or Celeron chip). Intel also extends support to several 100- and 200-series motherboards.

Pricing for Intel's Optane has fluctuated over the last year, but the super-fast storage devices still command a premium and come with much lower capacities than normal flash-based SSDs. To help ease the relatively poor price-to-capacity ratio, Intel recently announced its Optane Memory H10 SSDs, which blend the speed and endurance of Optane memory with the low pricing and high capacity of QLC flash–all on the same small M.2 device.

Importantly, these new Optane Memory H10 drives use the same caching techniques as the existing Optane Memory drives, making the new support for Pentium and Celeron processors more important over the coming months. The new Optane Memory H10 drives include two models with either 1TB or 512GB of QLC flash paired with 32GB or 16GB of Optane memory, respectively. That's a significant boost over Optane's 118GB limit on existing M.2 SSDs. Intel has yet to release pricing or performance information but says these new SSDs will come to market this year.

Intel's efforts to boost the uptake of Optane Memory seem to be evolving. The company recently canceled its Core+ bundles, which consisted of bundled Optane drives with a few of its popular CPU models.

In either case, you can now use the Optane Memory caching drives with low-end Pentium and Celeron processors. Pairing a $32 (16GB) or $62 (32GB) caching drive with a budget chip may seem counter-intuitive, but the caching drives do offer quite a boost to real-world performance over a single hard drive, as you can see in our Intel Optane 3D XPoint Memory Review.

Here are the system requirements for pairing Optane Memory modules with Pentium and Celeron processors:
