Is that it Marto? You're just going to keep ignoring me?

How much more clear do I need to make this?

YOU DID NOT SHIP MY ITEM
YOU HAVE MY MONEY

Do you realize that this is theft? Do we really need to escalate this? What do I need to do to get my money back? Go to the police?

Sorry about that Gator.
Specially for customers like you we are finishing now 4 chip version with normal heat sink and fans.
I hope it will be stable @ 130 range with nice 2-3w fans.
The damn chip is sooo power hungry

Update in Monday

This is great

I am sure many people will choose 4 chip version Grin

Are these A1's chips a different production run to the ones Bitmine are using? How did they manage to get 1GH/1W?
What about the Bitfury 2, is the ETA for that still March? I'm probably just going to wait for another chip.
If I cannot get these running quite I'll eBay them.
If someone can give me the lowest GH/Watt they will run at it would be useful before I pick up a temporary PSU.
But if not I'll find out tomorrow and report back!

They use more chips at slower speed to save power.

I'll have to go hunting for a PSU tomorrow, can anyone confirm 850mV it runs < 264W?

I was trying with frequency 200 & voltage 850 mV but the board not hashing just like stifla first screen shot Cheesy

Then frequency 240 & voltage 850 mV , hardware error 23% Shocked

OMG guys the fans are worse than I thought! MARTO! Shocked

BOTTOM FANS = Sunon PF92251V1-000U-G99/S99 = 92mm 12V 4.7W 4500RPM 46dBA 75CFM

TOP FAN = Sunon PMD1209PMB1-A(2).GN = 92mm 12V 12.5W 4900RPM 57.6dBA 120.2CFM

The thing is HUGE! Here it is next to a Hex16B!

I don't have time to mess with it today because it's valentines day and a couple of family birthdays too!

All the parts I need have arrived except the PSUs I had on back order.

I'll have to go hunting for a PSU tomorrow, can anyone confirm 850mV it runs < 264W?
I might just pick up a cheap 550W 44A to tide me over. It's using 17.2W just for fans!

On a serious note guys these fans are dangerous to little fingers. Keeps kids away/get fan guards. They only cost a few dollars.

I am currently running one board with a PSU where I use 2 rails 22A each, stable for 20 hours now with 980mV.

Here some picture of my board that just arrived Grin

And fan picture, i bet Gator-hex will be surprises Wink

Bottom fan is "SUPER FAN" SUNON PMD1209PMB1A rated at 12,5 W, 4900 rpm & 57 dBA

Upper fan is SUNON PF92251V1-000U-S99 rated at 4,7 W, 4500 rpm & 46 dBA

After trying some setting:

Hex8A1 Chip Frequency : 250
Hex8A1 Chip Core Voltage : 980
Hex8A1 Set ASIC difficulty to one : 1

Ampere usage on 12 V rail is 30 A

Alright, so the bottom one is the pain in the ass Grin

Do you think about any replacement options? I'm still on the looks for good fans right now

BTW: 30 A are quite ok, so you get approximately 1,44W/GH with this settings ,right? (i have avg 250GH/s)

Even with that 4900 rpm, the heatsink is very hot. So i don't want to replace the fan Cheesy

That is my rough measurement since i had to measure on 3 wire Cheesy

So around 1,44 - 1,5 W/GH.

When are you going to return the money you stole from me Marto? Do you think I will just forget about it?

order ref ?

ABOIPMBVS

Please do not send me the miner now. It is too late. I have made the order more than 4 months ago, so the miner is now completely worthless (due to drop in BTC value and increase of mining difficulty). I would like to have my money back please (you may send me in BTC).

@Marto74

(1) I would like to ask for a refund for my order that is more than 2 months old now.
Order reference: UICAWGFJD

OR I would like to get a HEX8A1 card as a form of consolation

(2) Why don't you react to messages sent to technobit.eu?

Best regards,

Marto, please answer.
Order ref is UICAWGFJD
