So I'm running 16.30 package w/ the 4.8.4-1-ARCH kernel (on arch) on a 6 x RX470 (Hynix) system w/ and I can do a few things w/ it...

I'm currently running a stock ROM.

I can use the overdrive w/o a problem, but pp_sclk_od only seems to affect the top speed, not the intermediate levels, so it's not really useful for me (I underclock for better perf/W and run at P6).

I can also overdrive the pp_mclk_od which would be more useful for me, but the 2000 strap timings are worse than the 1750 strap timings, so it's not a big win. Is there any way to adjust memory timings in Linux w/o booting into Windows/flashing a new VBIOS?

Also, is there anything available for adjusting voltage - really, just voltage offset would be fine (defaults to +4 on my Nitro cards, would ideally just like to bring them down to -10 or -12).

I poked around w/ mining a while (almost 2 years back) and am just recently jumping back in and it's interesting just how harder it seems to get BTCs these days.

Tonight I signed up w/ Coinbase, which has a decent exchange rate ($108.07), but I'm still waiting for the ACH verification. This of course isn't very private at all.

I looked into Bitstamp which has comparable exchange rates and the highest volume according to http://www.cryptocoincharts.info/#jump-btc-usd but wiring money in looks like a real pain.

I was able to use Paypal to VirWoX (USD to SLL to BTC), although by the time it gets in your wallet and you total up all the fees, I turned $50 from Paypal into 0.37BTC, or an equivalent exchange rate of $135.14/BTC - that's a 25% premium.

That actually makes LocalBitcoins seem pretty reasonable. There's some well rated people exchanging for cash at $125/BTC, about a 16% premium for anonymity.

BTC-e has the best exchange rate, but I take it it's really impossible to get USD in?

In any case, for just having some BTC to have/use/treat as an asset, it seems like Coinbase might be the most convenient way to get BTC in the US as long as you're not concerned w/ anonymity?  If you are, it seems like LocalBitcoins would be the best way, especially since things seem pretty locked down these days.

Voted. Looks like your plan is working. She's winning by a landslide so far!
