On other news, I just visited one of our mad scientists in his lab. The photos speak for themselves. Cool

This board only has 7 chips on (for reasons not worth going into), which means we're currently getting 2.24 per chip on the 8 board. Not bad. This is without proper cooling and various other tweaking on clock, voltage etc still to come, so we're looking good. Grin

Wow! That is great Barntech (and great news about the 6+2 PCI-E connector - all PS's have that or the 6 if older. Tons of choices out there).

You are getting just under 18 Ghash/s per board (if you had 8 chips). That is nice and such a huge jump from last week. Not really overclocking them much yet either. Good luck finding that perfect setting.

So small, I really thought they would be larger. (I can always put the mini in a larger computer case with a noise generator and blinking lights to get that effect though, just for when company is over of course! Grin

)

Thanks for the pics, nice to see. So exciting to be this close. Congrats.

Waiting for the go on 12V and I will order my Cooler Master V450S at 92% efficiency. (We need that with the rates here in Germany nearing .28 kwh)

Barntech (and others),

First great news, close to the decision on the PS. Maybe we can order later today and set up the Mining Shrine.

Question - Are the 6 pin Molex common connectors on modern Power Supplies? (Do they go by a different name?) As I can't seem to find many.

Looking at PS's I am not seeing the name "6 pin Molex". (And I'm hardly seeing 6 pin connectors, but on a few)

For example:
-Only 2 of the 7 low watt (300w - 500w) "Be Quiet" models have PCIE 6 pin connectors and just 1 at that (I think that is Molex as it is the only 6 pin listed.)
-I see no 6 pin on the cooler master series (see 6+2)
-EVGA 500 - I see only the 6+2 listed
-400 Watt Super Flower Golden Green - 1 x 6 pin PCI Express power (I think this is it).
-Corsair RM 450 - No 6 pin listed
-Corsair CX 430 - No 6 pin listed (both of these Corsairs list 6+2)
-Seasonic SSR 360 - 1x 6pin PCI-Express Connector

So, if 6 pin connectors are not as common on newer power supplies, be selective with which you buy. (Excuse me if I'm wrong here, just checking and don't understand all the terminology but imagine others are in the same situation.)

Can these 6 pin connectors be had via an adapter to an (e.g. 6+2 pin?, etc.)

Thanks,
IA

edit - From what I have read, I think you can use an adapter to go from 6+2 PCI-E to 6 PCI-E. Can someone confirm that?

The 6 pin molex hes referring to are PCI-E adapters. Most PSU's will have these connectors now, some will have 2, some 4 or more..

The 6+2 are simply an 8pin PCI-E adapter, where the 2 extra pins can be unclipped from the other 6 pins (as you see in the pic that Barn posted), similar to when ATX adapters went from 20 pins to 24pins..

Ok. Sorry for the confusion. It is this connector. Pretty sure they are standard with most power supplies.

IAS, i believe the 6 + 2 you were talking about is just one of these; can be 6 or 8 by just including the 2 or not:

Basically you will plug it in and it will take the power that it needs.

That sounds highly compatible with my preferences re: power/voltage.

Hey,

So if we go for the 12v, the connectors on the boards will remain 4 pin molex, but the connectors on the miniplanes and doubles scrolls will change to 6 pin molex. On the miniplane, probably only one will be required, but we may put 2 on just to make sure you'll get enough power. The double scroll will have 2 for sure. This means for all you ex GPU mine heads, your giant PSU will potentially be able to run four double scrolls.

That would be a good idea to include 2x 6-pin, as they're rated for 75W each, so 150W total. We'll have the option of using molex-to-6-pin adapters if needed.

They're called 6-pin PCI-e by the way, to avoid any confusion.

IMO good decision to use 12V instead of 5V, as the 3.3/5V rails on modern ATX power supplies are mostly an afterthought compared to the main 12V rail/s. Less efficient, and on certain models with group regulated designs, prone to go out of spec when put under a meaningful load: http://www.techpowerup.com/reviews/Antec/HCG-520/5.html

EDIT: 1x 6-pin PCI-e plus 1x molex would be another possible config, if it's practical to do. Every ATX PSU worth its salt has at least one of each of these connectors, so no adapters required.

The 21.7 is a good deal but the 2.7 thumbs are a bit overpriced.

Thanks Barntech Cool

So,no 5 volt needed at all,if you go with 12 volt,so I can make 4 pin molex's with or without 5 volt leads.More confusion,I know Cheesy

This you say, with bonus lack of question mark:

The only reason I asked is because the 4 pin molex has both 12 & 5 volt in the same connector Roll Eyes

Just trying to be sure I don't fry my boards or underpower them Grin

I gotta alot of "cleanup" to do but,heres my Klondikes rockin @ 5.5GH x 6,on my homemade cables.1 more above & 1 more below Cool

It is actually easy enough to buy some extension cables and set them up for 12v or 5v. I am betting that most computer geeks have at least 2 or 3 ATX PSU just lying around making. I would like to get the boards in my grubby little hands and then when the Drillbit team asks us what we would like or not in their future boards we could get that sorted out before they go to assembly.

12v sounds good, from what I've heard. I assume that a computer PSU of reasonably modern origins is what most people have been planning for their Drilling Rig©.
