Geil recently announced the availability of its new EVO Spear series of memory, with kits labeled specifically for either Intel and AMD Ryzen based systems. Geil states the EVO Spear series is intended for gamers, enthusiasts, and case modders looking for a cost-effective upgrade. The two flavors give one for Intel and the other for AMD Ryzen with capacities up to 64GB and speeds reaching 3600 MT/s (although not at the same time).

Geil says the EVO Spear series of RAM is optimized for Intel Core X, i7, and i5 Processors which includes the Z200 and X299 series chipsets. They go on to say the AMD Edition sticks are fully compatible with Ryzen 7, Ryzen 5 Processors, and AM4 motherboards, and we suspect that Ryzen 3 and Threadripper will be supported eventually as well. The only differences between the two versions are the QVL and compatibility testing - while most kits should work in most boards, the AMD kits are officially certified in various AM4 boards and Intel kits for 200-series boards. The maximum speed on the AMD Edition kits top out a bit lower as well. 

From Ryzen's release day, board partners have been working with AMD to further increase compatibility with AGESA updates via new BIOS, and the market is seeing more and more AMD compatible RAM at faster speeds as time goes on, so the updates are working. The AMD Edition sticks have an AMD Ryzen logo found on the packaging and modules, while the Intel sticks are nondescript. 


Capacities range from 16GB up to 64GB in both dual and quad channel kits. The operating frequency for the Intel sets is up to 3466 MHz, while the AMD Edition peaks at 3200 MHz. CAS ratings will vary by SKU but range from CL15 to CL17m and Geil offers a limited lifetime warranty on the EVO Spear Gaming Memory. 

The DIMMs use standard height heat sinks ensuring “zero mechanical interference” from the sticks. They are available only in a stealth black heat colored spreader with the EVO Spear name on the side. The heat spreader covers a black PCB, and in an effort to remain cost effective, RGB LEDs are not on the EVO Spear line.

In total there are over 50 different kits coming to market, divided by capacity (2x4 GB, 2x8 GB, 2x16 GB, 4x4GB, 4x8GB, 4x16GB) - the Geil website has the details. Pricing was not listed, however, a couple of dual channel kits are already available on A 2x8GB DDR4-2400 CL16-16-16-36 AMD Edition kit sells for $130.99 and a 2x8GB DDR4-2800 CL16-16-16-36 kit is asking $135.99.

    No lights and heatspreaders that don't look like Daenerys dragons! Hopefully others follow with similar products.

    Sadly timings are on the show side.

    Just out of interest, Intel doesn't seem to me to have an issue with RAM compatibility and I, for one, don't want to have to buy RAM and commit to one CPU manufacturer. Therefore, would it not make sense to buy the AMD one regardless, knowing it'll work with AMD if you chose to change in future and knowing that Intel doesn't have a compatibility issue? Or does Intel have an issue of which I am unaware?

    Intel doesn't have issues because they were the only ones using desktop DDR4 up to this point. The Ryzen specific DIMMs are probably guaranteed to use Samsung chips and not Hynix chips, whereas the Intel specific product lines might have either one. I could be mistaken though. Either way, DDR4 compatibility is a mess. I hope JEDEC comes up with a solution for this for DDR5. Some 16GB+ DIMMs won't boot past 1866...

    Hynix needs to work on Ryzen compatibility. Right now you typically have to go with something using Samsung B Die. That being said, I wish manufacturers would work on getting Ryzen/Threadripper up to 3600 with good timings for 16 GB sticks. It's possible to have up to 3866 in some cases, but not with 16 GB sticks. Maybe AnandTech should do a memory compatibility article with Ryzen, Threadripper, and Intel's top end offerings.

    Is there a way to quantify speed gain for a higher clock but higher latencies?
    Meaning, how much does going to 3466 gain, if the latency increases to 16-18-18-38?
