The seller says 2Gh/s but with Bitminter is working at 1.5 Gh/s What is going on?

You need to adjust the clock speed for your AntMiner U2 device(s) to achieve the advertised 2.0 Gh/s. BitMinter client versions 1.5 and newer support this feature. Go to "Tune and Tweak" and change the clock speed value to 0981. Your U2 device(s) will then run at the expected 2.0 Gh/s.

It is slightly slowly than high speed internet. I sent the device back because of the onerous terms of agreement that you had to give them a credit card to sign up for service. If I were you...look into the Karma device, it has no such agreement and is just as fast.

Have the same problem. I will try some steps before it goes back to Amazon and a negative review for the vendor (V4ink)

It is 1866MHz but it'd work with your system, just set it to the correct speed and everything should be fine.

Something is not right there. On a wired 1Gbps connection with a single copy I would expect at least 400Mbps, with speeds over 700Mbps on faster switches (efficient internal packet forwarding). That is from testing when I first received the unit (tested with 4 x 5200 RPM Toshiba 160GB in RAID 5, prior to 4 x 7200 RPM Seagate 750GB in SHR I have had in it since then - but I haven't tried that on a fast switch, my home switch seems to max about 500Mbps).For comparison, I've seen speeds close to single line speed (~900Mbps) on a DS713+/DX513 combo.If you are on WiFi, I would run hardwired tests for comparison. Then start troubleshooting your WiFi. Something is not right there.

Yes it is but ,I don't know at the same place it write 260m and other time write 210m how can I fix it?

If you are using an older machine that does not have USB 3.0 support the slower transfer rate can cause an issues such as this and there is no fix. If you are using a USB 3.0 port make sure your motherboard drivers and bois settings are up to date. After trying all this if the drive continues not to perform to your expectations I would exchange it for a different one.

Good Question for Amazon if they have both speeds posted. It is 5400RPM NOT A 7200 RPM

Thanks for the response...the first 2GB i received from Amazon actually seemed to slow DOWN my netbook...esp noticeable after i replaced it with the 1GB to see if the hanging shutdown would go away (which it did)...so my question to you is...do you notice ANY enhanced performance from the 800 mHz 2GB install?

I have one and it is 256bit, I am also getting another and it also says 256. Hope that helps

Hey, My understanding is that the base speed is 1.33 Ghz with the ability to go to 1.86 Ghz (like a turbo) when needed. I think this is done to save or provide better battery life without affecting performance. My also displays 1.33 Ghz. Grim

It appears that the Writing speed is about 5.60 MByte/s and the reading Speed is about 7.37 MByte/s. This is based on some of the tests I was able to run on my PNY Attache III 16 GB USB 2.0.

They don't publish what speed it is. They source different hard drive manufacturers. More than likely it is 7200 to meet the specs. From the various reviews from professionals, it meets their published specs. The transfer rates are very good. I liked mine.

As JohnK mentioned, SHA-256 only... 38 MH/s for scrypt at this price would be amazing!

Sorry but I´m acctualy dont have the bit-extender son i don´t know how works in it. Sorry also mi english.

Guess is a product malfunction the machine should maintain the selected speed. The one I owned has no issues of this kind. Should Call customer service for any specific instruction if problem persist suggest to return the product back to them.
