I can understand that, but when they say you'll get shipment and tracking on the 27th that's kinda what I expect. Anyway I'll keep chasing...

Well I've tried email to the website, PM's on here and phone calls - nothing sadly. Eager to take BTC but not to provide any further communications. I'll be requesting refund at COB today if I don't at least get an acknowledgement of communications. Pretty shocking really.

What makes you think any new request, especially for a refund, is going to get any response?

My card is now dead, it never hashed to the minimum spec and no one from VMC or Ken has responded and probably never will, if recent history is any guide. VMC could have been something good if only someone, anyone would put on the customer service hat for a day and answer some requests...

Edit- I received a blurb from Ken on the VMC site that the warranty is 10 days for DOA. I am not sure if this is Ken's way of saying "tough shit" on a card that died within this 10 day period and never performed as advertised or if this is a general statement, so I responded with how to process the replacement of the card that died within this 10 day period. We shall see...

Forget-about-it

OP has these "750G/hash" for $849 and sells the older or other chips "512G/hash" for $1999 what gives? Im interested in the newer one if the price matches to performance. I mean if it was about 20% less since most see 20% less performance.. Nice design either way. Look forward to seeing the manufacturer paying a little more attention to this thread!

Has anyone received tracking numbers from orders over the holiday weekend? Promised on Tuesday but still have have nothing.. Sad

tracking will appear in order details.. open your order and look closely.. mine was sent via fedex although it said dhl

got nothing on my order sadly, was paying my BTC and it was done via PM on here

did you got e-mail that order was sent?
someone mentioned that Ken headed West.. maybe he is not in office to ship your order?

Did you remove some of the mounting plastics for the heatsink, or you used what was stated in the h110 manual? seems to me it should be possible to get it close enough by removing one of the small plastic clips, allowing it those extra mm's more closer to the cores..

never looked at the manual

this was my final solution:

ok, here I go:

indeed, using parts that came along with h110 watercooler, it is not possible to fit it on card, there will be a small cap..
so I used kids construction parts that were laying around.. and fitted into coolermaster mini-itx 130 case, I must say H100i is easyer to install on the miner board and into that chassi, also H100i is same size as air-intake holes on the side of case, although I leave cover off..

Temps seem to be about the same.. this card was 659GHz tested, 0.88v.. for me eligius about the same performance or maybe a 20G+ more.. time will tell..

Still I wonder how to rise voltage to the same step as "tested" label indicates...

I must say I lake the design of my miner.. If building it would not be so expensive and time consuming, I would add rPi and voila, you would get a nice miner

for now I have some more to build for myself Wink

EDIT: ok,, system with H100i get hotter.. it sits infront of air ventilation hole and gets hotter than system that has H110 and is next to it but does not have fresh and cool air ventilation hole in front of it.. so for next systems for me it is H110 or H100i + better fans..

Thanks for the update

did you manage to get it in contact with the cores? another stupid q - are you having the fans blow into the radiator or out from it? doesnt say in the corsair manual.. Huh

I installed fans to pull air inside the case through radiator and out. case has one 120mm and one smaller fan to push air in, also case is open in the back, so air can flow freely around the PCB also.

yes, it is in contact w cores

Well I am sad to report that my GR card is no longer recognized by any system after I plugged in an additional fan to the board (fan 2 header). I am now at a loss. The board powers up with the normal lights and the normal indicators when USB is plugged in. after that, nothing is recognized.

What I did to "cause" this...
1. All systems running stable ~600GH/s @ ~90C @ 800MHz
2. Power Card down
3. Plug additional fan into fan2 header pins
4. Power up card (new fan was spinning)
5. nothing, card usb not seen by multiple systems.

Anyone have any troubleshooting ideas here?

I contacted Ken and company but have had no response.

My card was running off and on (off for liquid block placement) for roughly <2 weeks total.

Thanks!

Had the same thing the other day, I pushed the reset button on the card, it rebooted and showed up on my pc.

2nd thing I did...

Still no joy.

One time I lost my card also, I powered it off, then removed power cable, and powered it on again (without cable) so all those energy things I do not know the word in english will disappear and after that my card was happily found and hashing again

btcguild reporting:

that is two (2) cards...
Sad

EDIT: hashrate seems to jump up'n'down a lot... tomorrow I can give a graph.

Ken just informed VMC shareholders that he was heading out West to work at tweaking miners in the ActM mining farm. Perhaps he'll come back with some instructions on how to set these units up to get closer to the advertised speeds?

How are the miners performing?

at least 13% under the promised 750gh/s spec. over 30% under spec in my case.

Has anyone contacted VMC to see what they'll do for miners that fall outside of the +/-20% variance?

It seems that ~650Gh/s is a more realistic expectation from these.

Yes. Nothing but us crickets here...

I think it's pretty well accepted at this point that they'll ignore you and your inquiries.

Other then for payment, yea, so far, nothing...
