That post about a different machine from a different manufacturer solved your SP10 problem? I am skeptical.

I think I've got it but I could be wrong.

I use one of those 49-port hubs for testing, and some inline meters. I test batches of 25 at a time at 200MHz, which means around a 20-25A draw through the hub without any problems at all and I've been using it pretty much continually for going on a year. They're pretty nice.

If you have suitable skills and knowledge you can get a cheapo hub without current regulation, beef the 5V and ground rails, hook up a stout 5V PSU and wind up with a 100W-capable hub for not a lot of dollars.

Reckon they'll do like they've done a couple times before and reopen sales in a couple hours once we're all panicking and desperate?

Not from my own experience - being the manufacturer, my setups tend to be somewhere between "cusom" and "industrial". There's a lot of good info in this thread but I don't think it's consolidated anywhere. I know the name "Superbpag" (or something like that) comes up a lot, and what, Anker? makes a good hub.

If they're US green-heatsink sticks, you should have no trouble hitting 200MHz at stock voltage unless they were bought used from someone in which case they could be set who knows where. If one stick works fine but multiple sticks does not, I would doubt the strength of your hub.

Have you looked at the troubleshooting section in the first post of this thread?

Unless I have good reason not to, I'm assuming to use the same heatsinks/screws on future versions with new chips so a setup built for BM1384 Compacs should work on newer ones too.

Yeah, the chip is 8mm per side. Somewhere in this thread I posted the mechanical specs for the heatsink if you want to know screw positions or anything.

Actually the stock setting depends on your software. I think our cgminer defaults to 150MHz, but BFG defaults to something like 225MHz. You actually have to turn the voltage down a bit from stock to get 500mA draw at 150MHz but it's close.

USB3 is 4.5W, 5V 0.9A

USBC is up to 100W, but that's a whole different breed of cat.

And there is no specific "what the compacs were designed for", not really, since you can pull 15W with one if the hub allows. Good mining hubs don't limit you to 500mA anyway, but most good mining hubs could only source about as much power as the Compac can safely dissipate with a good fan. I think that's what he meant.

My mom knew well enough to understand early that racism and its ilk were foolish and raised us kids to think about people as people rather than targets. Subsequently I have more hangups about people who are fine with being lazy or dumb and not trying to do better for themselves than about any race or sexual preference. Considering the neighborhood, I feel lucky to have had the parents I did.

Fan control on the Dell 750 board is a basic pot. The DPS2K board (out of stock and pending some redesign) has adjustable PWM to two 4-pin headers for external fans. The DPS8/12 board doesn't have fan control because those supplies are internally regulated. Current measurement was done with a low shunt resistance and sense amplifier, but the feature was so little used compared to cost it's been removed.

I used to say I was proud to be from Missouri, but then I started learning more about other people in the Bitcoin world. BFL, VMC and MinerSource are all from Missouri; Minersource started in the same town I'm based in, even. Yes there are a lot of hicks in MO, and I did grow up on a farm, but if you know where to look you can find a lot of really smart people and if you really know where to look you can find smart hard-working people. Rural upbringing does wonders for the work ethic.

I supplied a lot of PSUs to Maxime last year, before they started doing a lot of work in-house - both breakout boards and hard-soldered cabling. Folks who can do their own rigging like you don't benefit nearly as much from what I do, and I'm certainly not going to be upset about self-sufficiency.

Glad I caught your edit before replying. My only affiliation with bitcoinware.net is they bought my stuff to resale in Canada, same as my affiliation with HolyBitcoin and ASICPuppy in the US. If it has my name on it, I manufactured it in and shipped it from Missouri, USA regardless who is the reseller. The only place I have ever listed Compacs for sale is on this forum, so if you see them for sale anywhere else it's a reseller (authorized or otherwise) and I claim no responsibility for their actions. The only website I'm "behind" is my own sadly neglected one, gekkoscience.com

Are you asking about 1/4" quick-connects to tie directly onto the power blades from the PSU? You could have asked, because I've made cables like that. I don't think it's a great long-term solution but it works. I have some temp supplies in hosting set up just like that.
Also all my breakout boards have an active-high external turnon pin specifically so it can be used alongside an ATX PSU without additional hassle. My first server PSU mods were for a GPU rig, so that feature's been there since the beginning.

It shouldn't be too hard to get power to the chips with a different PSU, but I don't know if the miner's control board actually requires being able to talk to the PSU (how it gets the data/stats on power use) or not. As for running on one PSU, each PSU directly powers one of the big hashboards so without rewiring (and serious downclocking) you can't run both off one PSU. What you want to look for is a setting like "restart mining if hashrate is under xxxx" and lower the number to a minimum for one board - probably around 2TH.

Sounds like you don't want it. That's okay. Can I get opinions from the other side?

Vcore and the CP2102 never interact, so I'd question why both were reading off. The 3.3V from CP2102 only interacts with the ASIC indirectly; the closest it gets is through a resistor divider or a pullup resistor on an open-collector output. Should be fine. But that doesn't explain why the Vcore is bottomed out.

Let's see what Bitshopper has to say, and if he can't fix you up let me know.

I don't have anything for the DPS2000 right now, but I have an HP Common Slot board (which has PSUs from about 500 to 1500W Platinum) with 12 PCIe jacks.

All I have for GPU-rig-specific hardware right now is cables. The 4-Molex conversion boards are still in prototype. MarkAz specifically requested ATX24 conversion boards so he might get dibs on that depending on how everything works out, but I'll try and build 'em one way or another.

Yes
