Why not ECC ram? Lot of AM4 boards support it.
- resonanttoe 3y agoDoesn't look like the 3000G supports it. https://en.wikichip.org/wiki/amd/athlon/3000g https://en.wikichip.org/wiki/amd/athlon/3000g
- yasuocidal 3y agoAFAIK, all ryzen cpus UNofficial support ECC, its up to the motherboard IIRC.
- dannyw 3y agoNo, the 3XXXG series do not support ECC; which simply do not work. This is because the iGPU doesn't support ECC RAM.
- Dylan16807 3y ago> This is because the iGPU doesn't support ECC RAM. What, how? The only part of the chip that touches the ECC bytes should be the memory controller itself. The reads and writes going across the internal fabric should be exactly the same. Also the PRO versions support ECC and seem to have the same iGPU.
- cassianoleal 3y agoOnly PRO CPUs do though, and they're only available as OEM parts of complete systems, or second-hand that's been ripped out of them. :) On top of that, finding compatible ECC sticks is not easy and they can be quite pricey.
- TwoNineA 3y agoMy Ryzen 3900X supports it fine, ASUS Prime Pro 370 and 570 boards. Using 64 gigs of this: https://media.kingston.com/pcn/PCN_KSM26ED8_16ME_C1.pdf https://media.kingston.com/pcn/PCN_KSM26ED8_16ME_C1.pdf
- cassianoleal 3y agoRight, it looks like it's for APUs where only the PROs are ECC-compatible [0]. Given that was one of the requirements of the OP (integrated graphics), my point even though technically imprecise, still stands. I have the same memory sticks. They cost £157.86 each 32Gb stick. That's over 2x the price of non-ECC sticks of otherwise similar specs. [0] https://www.asus.com/support/faq/1045186 https://www.asus.com/support/faq/1045186
- ThePowerOfFuet 3y agoYou buy that memory once, then run your precious data through it for years. Sounds like money well spent.
- cassianoleal 3y agoAssuming the data being accessed by that RAM is precious, you're probably right. In fact, I agree so much that I spent that money. I wasn't making any value judgements though, only posting observations.
- Dylan16807 3y agoYou could use that same logic to justify a $30 power cable, though.
- ThePowerOfFuet 3y agoNo. Power either is there or it isn't.
- cassianoleal 3y agoThat's not quite true. Power fluctuations can cause instability or crashes, either of which could lead to data corruption. That said, it's much more likely that a faulty or low quality PSU will be the cause of that rather than the cable, and there's a lot already written out there about why a high quality PSU is important.
- HansHamster 3y agoI think most Zen CPUs support it, but only the PRO APUs. Just upgraded my NAS a while ago after upgrading my main PC and replaced the 2200G with my old 1800X and some ECC ram, but also had to install an old GPU because that one doesn't have an iGPU.
- Fnoord 3y agoI'd go with ECC RAM even if it costs a little bit more, same with an enterprise NVMe SSD. The latter is worth it in case of a power cut. It allows you to enable write cache and using the SSD as ZFS cache, massively increasing performance if you are using mechanical HDDs. This guy goes full SSD, but for the content he serves that isn't required at all. Also, just have enough RAM, but don't disable swap. Put swap on an enterprise SSD but let Linux handle it. It will do so cleverly. Whereas with RAM only you cannot use swap at all. Minor disadvantage is you should encrypt your swap. But with modern hardware that shouldn't be a large penalty.
