TL;DR: can I max out the ECC cap on the motherboard and turn the ECC feature off to have more RAM, with normal speed?
sorry if the title is somewhat vague, I don't really know how to put it right
so, I am planning to make a cheap somewhat temporary build using old Xeon parts, I already have high-end GPU (well not really, an XFX R9 280x) and PSU (850-watt platinum EVGA p2) and SSD (1tb Samsung Evo) so no need to give suggestions on those.
I am looking at this board:
http://www.supermicro.com/products/motherboard/QPI/5500/X8DTU-F.cfm
with a dual Xeon x5680
it says it supports up to 192GB of ECC RAM or 48 GB of unbuffered ram
can I buy let's say 192GB of ECC RAM and then turn the ECC feature off to get faster ram?
I have no need for the ECC feature, I mainly do Blender Cycles rendering and work with Blender game engine/Unreal, I do backups often. it is nothing crucial to have some errors here and there. I also am planning to make use of ramdisks if possible...
but will it work? will it give me an error or something, and I'll be stuck with 48GB of unbuffered ram? or not even allow me to use the computer?
edit: I know it is a lot of RAM, and it is quite expensive, I just want to know this type of information before buying anything.
Also, if you guys have some idea of a better CPU/mobo ( to buy used) for about the same price (-U$100), I'll be glad to know. I can't find a motherboard with socket 1567 for the e7 2870, more cores the better but speed, PCIe lanes, and SATA ports are also relevant, unlike power consumption. I don't remember if Tom's hardware won't accept this type of multiple question thread. if they don't just ignore this part and I'll make another thread.
any tips are appreciated, thanks,
Marcus.
