On facebook marketplace, I found 16GB DDR4 (8GBx2 2666Mhz) for 3k. I quickly tried to buy it, but they said the ram would only work for intel cpus/mobos.
The model of the ram is aeI8GD4U26M16C (ant esports 690 neo fp 8GB). I think they were just confused by the marketing materials saying that the ram is tested with intel kits. I am thinking of just buying it, hoping that the ram would work (DDR4 is DDR4).
Just in case, I wanted to confirm with folks here, if there really is ram that only works with one cpu platform and I may be committing a mistake.
“AMD only” was a term for DDR2/DDR3 rams that were out of specifications as intel systems didn’t supported anything out of specifications back in those days.
I haven’t heard any RAM termed as intel only.
It only has an XMP profile, not the AMD equivalent.
It uses lower grade DDR4 chips that are incompatible with Ryzen’s demanding memory controller.
It’s likely #2 since it’s a budget brand. I have an 8GB stick of DDR4 that works fine with Intel 6th and 7th gen but just won’t boot on any AMD Ryzen system.
Yeah me neither until I got curious about why eTT ram was a fraction of the price.
I guess for memory, you really need to go with a reputable brand, they’re not all the same, and you only go for the cheap stuff if you’re looking for something almost disposable.
I thought all memory was the same, just binned for different speeds at higher prices. But nope, you gotta stay away from the junk brands.
You can overclock it manually, XMPs are just OC profiles that are almost always able to run on most PCs. Usually if it says it can do XYZ speed with XMP you can push it further if you manually OC it.
What most likely happened is that the user checked speed on task manager and it showed as half the speed of the rated 3200mhz which is 1600mhz. Windows supposedly released update to “fix” this and show full speed (now listed as MT - Megatransfers instead of in mhz) but the reviewer didn’t update his windows.
I’m facing the issue that you guys are discussing here.
I’m planning to buy 2 x (16x2) kits of identical G-Skill Trident RGB RAM (not NEO). But the thing is, it says that these kits support XMP 2.0 on Intel. There is no mention of AMD, and these are pretty dated models and apparently the NEO sticks are the ones meant for Intel.
In your case it’s likely the older sticks don’t have AMD-specific profiles, but they’ll work just fine, G.Skill wouldn’t be using the lower standard memory chips.
In fact I’d guess any ram that doesn’t offer lifetime warranty is using the lower grade chips, like 1 year or 3 year warranty. I’d stay away from those brands unless if the price difference is huge and you’re okay with it become disposable after the warranty period.
Years ago when I was starting out my homelab/server journey, I came across some ddr3 sticks on AliExpress that were AMD only, and were suspiciously cheap, I’m talking “general” option 8GB at 1.8k, but “amd only” at 1.2k . Assumed the sticks just aren’t tested on intel systems, and purchased 2 sticks.
Once they arrived, put them in my i5 4400 system, and nope, didn’t boot. Mixing those sticks with a normal DDR3 stick would get me to uefi, but the diagnostics menu would just show “undefined 8GB” and would not count towards the total capacity in any OS. I had a couple of AM1 systems that I had purchased off of @rsaeon iirc, and they booted up just fine with the weird sticks. That day I found out about dram column address bits, chip density and non jedec standard configurations. One of the sticks is still in use in an AM1 machine that I’m running pfsense on.
On the contrary with ddr4, intel CPUs are far more tolerant/robust in dram support, and I’ve never come across a kit that didn’t run on a ddr4 intel platform. I have 2x32gb patriot ddr4 3200 sticks, both fail memtest in a ryzen 3000g + a320 system, but will run memtest happily in my intel 12100 + b660m server. Sample n=1 for both platforms, so take that with a grain of salt.
Only ECC Rdimms are exclusively compatible with intel motherboard and incompatible with amd motherboards, other than that there’s none. That’s the only reason why x99 motherboards are still very popular
