sorry guys, been really busy & some unscheduled urgent appointments showed up. i'm around though. those who pm'ed me, i did reply & will deal with shipping by this coming friday. apologies.
OP i solved the HighPitch solution for you hahaha ... psu is cooler, less load + better efficiency too.
single 1200w platinum server psu is not enough for your power hungry multiple gpu setup? well the capt got a dual solution! *ordered a small batch of customized dual c13 cables*
running your miner in a hot environment? hot psu? fans are screeching? no problem cooling solution is here too...**i'm running & testing 2 sets now without the extra fan, it's cool & quiet
some stock arrived, SOLD OUT ! 100 risers, gonna order another batch, this time round 50 shorter usb cables & another 50 regular 60cm ones. rigs will me much cleaner !
after some drilling then continue with lots of screwing
more work to be done, enjoy folks.
as for multiple gpus setup more than the regular 7, i won't really recommend to most people due to :
1) you will need NOT only custom BIOS but probably some mods in WIN too but for more than 8 it has to be linux for sure
2) for the 16 or even 32 gpu setup, it's amazing development but still no pix & it's a meh for me tbh.
YES there are some indicator on the boards if a GPU hangs & the mining continues, good job, -wd 0 can do that as of now too but nevertheless the operator still have to RESTART the mining software in order to get all gpus up & running = longer startup time for DAG generation = more gpus will be down = more downtime. what we actually want to know is more towards which gpu is down & which is the one that needs to be adjusted ie in WattTool or in any other software or parameters.
3) Extensions are good for up to 2 gpu or probably even 3 on a single extension BUT either BIOS or WIN limit will hit ya (WIN will be something like NOT enough resources)
4) then it could be fleet of psu's that an operator will need to run & or to figure out the cables & wiring mess, sorry folks & yes i am NOT a fan of messy cables.
5) the boards will be quite BIG in size to fit all gpus = a new design for a rig/rack to fit all of them. say to fit all 16 gpus side by side with a decent amount of spacing between them for adequate cooling the width has to be a minimum 130cm or more.
6) i'd really like the no risers idea & the capability to run many gpus at 1 time but as the old saying goes, do not keep all your eggs in 1 basket.
KISS is sometimes the BEST solution to most problems.
OP i did NOT buy all the mobos HAHAHA.
**again, i DO NOT intend to be the "bad guy" here with regards to the 16 gpu setup but it's just my personal opinions i hope it's being viewed & taken as a constructive criticism**
