How about some consumer desktop ones with ECC RAM support?
- mamon 9y agoNever gonna happen. ECC is "pro" feature for Intel, reserved for Xeons only. They have to justify high price of Xeons somehow.
- TazeTSchnitzel 9y agoEven AMD think of it as such. Ryzen doesn't have it disabled on the desktop, but AMD haven't validated it either.
- agumonkey 9y agoDidn't AMD employees confirm it a few times on the web already ?
- onli 9y agoECC is working with AMD if the motherboard supports it, but you can't always be sure that the motherboard does support it correctly. You need to rely on user reports/what the motherboard producer promises, instead of it being a default feature that always works. Still a lot more than what Intel offers in that space.
- agumonkey 9y agoThanks
- TazeTSchnitzel 9y agoI didn't say ECC doesn't work. It is enabled on Ryzen. But it's not something AMD go to the effort of validating to make sure it works properly and it doesn't get support. It's left in there as a footnote for enthusiasts.
- sborra 9y agoIf I'm not mistaken there are a few Pentiums and i3 chips that support ECC. For example the G4560.
- chx 9y agoYou mean server chips. The server Atoms also support ECC. For eg. https://ark.intel.com/products/97927/Intel-Atom-Processor-C3958-16M-Cache-up-to-2_0-GHz https://ark.intel.com/products/97927/Intel-Atom-Processor-C3...
- jpalomaki 9y agoWhat's the price difference between consumer (no ECC) and workstation (ECC support) (mobo+cpu+memory)?
- sliken 9y agoXeon E3-1230 varies by generation (v1 to v6 or so), but is typically slightly cheaper or slightly lower clocked then the top of the line i7. The motherboards are about another $50, and the dimms are another 25% or so more than non-ecc dimms.
- k_lander 9y agoWhy is ECC sought after on the desktop?
- bitL 9y agoSome people run >32GB RAM with long uptime and there the chance of a random bit-flip might not be acceptable. Imagine working on some Deep Learning model, training it for 30 consecutive days and then hitting a memory bug during computation.
- Synaesthesia 9y agoNot your everyday requirement, also ML is somewhat tolerant to small faults like that.
- bitL 9y agoDepends. If a bit is flipped in a dataset you are likely fine, if in code your computation might crash. If you use enterprise-grade software like ZFS filesystem that keeps a lot in memory, it's much better to have ECC and accept a bit slower memory access for a bit better protection.
- OoooooooO 9y agoZFS without ECC is pretty useless ...
- michaelmrose 9y agoZFS is no more vulnerable to corruption when running without ECC than any other file system. The developers of zfs suggest ECC because ECC is a worthwhile thing for those who care about their data. You should stop spreading misinformation.
- Retr0spectrum 9y agoRowhammer protection, for one thing.
