Considering a super-cheap mining rig, i've came across the 5770. However, the page at https://en.bitcoin.it/wiki/Mining_hardware_comparison seems awkward: Model | Price | Avg. Mhash/s | Mhash/J | 5770 | $136 | 212.83 | 1.45 |
if the 5770 has a MAX tdp of around 108W, shouldn't that be more like 2.0 MHash/J? OC'ing 3 of these could get about 700MH/s with around 400W total load: somewhat efficient and cheap The reason for the 5770s, is mainly for how easy it is to buy and sell them used, making for a less risky investment than a high-end card... Comments welcome

I think that to get 212 Mhs with a 5770 it must be already well overclocked. One of my rigs has 2 5750@870/300 hashing at 172 mhs each, running fine 24/7 with an old 500W PSU. I found them at 50 euros each used (one on ebay included delivery).

Silly me, you're right. I've looked closely at the charts again, about 180MH/s seems to be the default for these cards. Still, that would mean 1.8MH/J at stock, much better than 1.45.

I have a 5750 (which is 5770 but with insignificant lower speed frequencies) and I'm doing right now 54 Mhash/s. I'm in the BTC Guild, using GUIMiner.
I thought I would have at least 150 Mhash/s... what's the problem?

S/t is way out of wack. You should get triple speed at stock clock. Are you watching videos or playing all the time? If not, try with Phoenix or reinstall the drivers.

Thanks for answering! I have updated my drivers and now it's working @ 135 Mhash/s. Also, I have added at extra flags this line: -v -w128

Consider the single-slot 5770. It runs cooler, more efficiently, and has XFX's Lifetime Warranty. See my sig, I have one left if you're interested.

Its scary how much of a difference this makes. I did this on my 6990 and it shot up to around 720mH/s
