1  Alternate cryptocurrencies / Mining (Altcoins) / Good tester for USB3.0 A/M-M cables (for risers) ? on: July 25, 2017, 09:10:02 PM
Could you recommend me good tester for USB3.0 A/M-M cables? Inside are 9 wires - http://imgur.com/a/KGTcM

Recently I bought big quantity PCIE USB 1-16x risers from China and I have trouble with them. If more than one card in the rig it is not hashing only pcie errors. When I replace USB cables it works ok. Previous batch from the same supplier was ok.

2  Alternate cryptocurrencies / Mining (Altcoins) / Biostar TB250 BTC compatibility with M.2 to PCIE adapter on: June 15, 2017, 01:14:47 AM
Is mainboard Biostar TB250 BTC compatible with cheap chinese M.2 to PCIE adapters?
like this http://www.ebay.com/itm/High-speed-PCI-e-1X-4X-Card-to-NGFF-M-2-M-Key-PCIe-Slot-Converter-Card-Adapter-/322553862111?hash=item4b19b557df:g:G9kAAOSwi8VZP7Uw

Somebody with experiences? I need to use 7GPUs on this mainboard and I have trouble with it.

Also I found another more expensive version

Make it sense to buy this version?. Or it is the same as cheaper version above from ebay?
