" rel="nofollow - Hi new here. Looking at picking up the above board for a couple of v3 Xeons to avoid my previous Asus z9pe-d8 ws nightmares. Does anyone know if it accepts unbuffered ECC ram? Or only RDIMM's. Trying to save a bit of money, ECC RDIMMs are at least twice as expensive as consumer dimms, but at least unbuffered is marginally cheaper. 64gb ddr4 ecc rdimm is going to put me back around 900 USD after import duties here. May even have to go the new Asus board to cut back on costs (consumer ram much much cheaper and readily available used). For 3d rendering, so can live with the odd memory problems, not doing high finance. However, my OEM cpu's (e5-2696 v3) are known good with the asrock board and want to avoid various pcie and bios, chipset nightmares occuring with the asus board if possible. Still....950 bucks for memory, or much less than half that! and deal with usual Asus headaches. Current z9pe-d8 ws has been stable last 3 years, but took a lot of cussing to get there! This is for home experimentation obviously, not work. Still waiting for reply from ASROCK tech support.

The best I can tell you is the memory types that are supported are dependent upon the processor itself, since it contains the memory controller. If we check the specs of a similar E5-2697 v3, the Memory Types simply include DDR4 1600/1866/2133 with nothing about a requirement for RDIMMs: http://ark.intel.com/products/81059/Intel-Xeon-Processor-E5-2697-v3-35M-Cache-2_60-GHz" rel="nofollow - http://ark.intel.com/products/81059/Intel-Xeon-Processor-E5-2697-v3-35M-Cache-2_60-GHz ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Thanks for reply. Can't figure it quite out, ASRock rep emailed me saying I would sic 'brick the bios' if I used UDIMMS...but on the other hand tweaktown did a test with generic udimms and seemed to work fine. Same discussion with the z10pe-d8 ws. https://www.techspot.com/review/1218-affordable-40-thread-xeon-monster-pc/#allcomments) A lot of people harp on and on about RDIMM, but have seen for both boards people have successfully used udimms. This is for 3d rendering, not mission critical stuff. Can understand using rdimm when using very large ram sticks maybe 32 and 64gb modules. How do you brick the bios anyway? Thought you had to go in with a hex editor or flash it to make changes.... thanks. The price difference is around 500 bucks between normal udimms and ecc rdimms (for 64gb). Addendum: I could pick up 2x rdimm ecc 32gb modules relatively cheaply (600 usd), but not sure using only 2 modules (1 per cpu) would even boot. Would be brilliant if it would. ECC RDIMMs are very hard to come by cheaply here in scandinavia. Just can't pony up the 1200 usd for 128gb at the moment, and only need 64gb for 3d work and video. In fact, 8x8gb here is going to cost me 950 bucks (due to 25% sales tax/VAT).
