usb block eruptor 470MH OC?

[Condortra]

hello.

at this shop they sell usb block eruptors OC 470MH  HERE :  http://bitcoinit.bplaced.net

so anyone knows to how to OC them? and can i OC mines also? i mean can noobs oc it? lol

greetings

You need to replace resistor R1 and oscillator.

any English thread ?

pls in english

Considering Im not able to do it myselves, how much does the oscillator + work would cost?

Oscillator + resistor about €1.20, then find someone who can do SMD soldering.

i bought all needs for an oc

i try to oc one of my eruptors now i report the outcome asap

[Condortra]

just trashed one eruptor....

Somebody told me it could reach 600MH/s with some equipment... 

[Condortra]

i was able to oc one its runs now smooth with 483MH yay

finaly after 5 hours lol

For a complete novice, let's say I bought one of these overcloced units. So I would be running 470mH/sec -- What does that yield (on the average) in a 24 hour period if you were to mine it solo? I'm curious.

How difficult was the overclock? 

I've got little to no soldering experience (or real hardware electric circuit experience) but I'm generally good with my hands and am interesting in modding my usb erupters just to learn a bit more about how they work.  I've read the instructions a few times and it seems really doable.  Just an issue of purchasing all the equipment

[Condortra]

extreme for me i am complete noob lol

but managed it somehow

well i think you cant mine solo just with 470mh..

but even when you buy the device  it will make you 0.0027 BTC (1 oc device) at day by an pool mining

i didn't know it could be overclocked.
does OCing it damage the hardware faster?

[Condortra]

i dont think so its just abit warmer

[balanghai]

This is not overclocking but instead changing the oscillators frequency by replacing the crystals. This won't hurt the hardware. Just use a proper air solder and controlled environment when doing so.

excactly

Do you know why the manufacturer did not do this?

i have no clue, i think they didnt knew it lol

did the prices reduced at the shop? oc eruptor only 0.19 lol

1-2 days ago was it 0.30+?

Increasing the toggle rate of the chip's transistors increases power consumption. Friedcat wanted to keep the block erupters within the USB specification which is 500mA @ 5vdc

Increasing the clock rate beyond 14Mhz will probably require a vcore voltage boost (replacing the resistor sets the asic core voltage regulator to a higher voltage)

Higher core voltage puts more current through the gates and increases stability but is harder on the chip and will reduce its lifetime.
