What you're after is a Voltage Controlled Oscillator. Something a 555 can be made to do.
Feed said VCO with the PWM signal after said signal has been turned into an analog voltage by a RC network, and presto.
You are not likely to get 0-733Hz easily without a microcontroller, though.

I've yet to run into a motherboard fan header that cared about getting a TACH signal back when it's putting out PWM, or one that used any feedback.
Every board I have worked with, used, benched on, or reviewed the PWM output % has been based solely on CPU core temperatures, nothing else.
The health monitoring section wants to see something on the TACH pin, but as long as it's over ~250RPM it doesn't care either.
My experience is that the mainboard does not command the fan to run at X RPM at all, it simply says "Run 50% duty cycle!". This is backed up by the duty cycle for a given core temperature being the same regardless of whether I'm using a fan that does 700-2000RPM or 0-6000RPM. All the motherboard/mainboard cares about is core temps and duty cycle.

EDIT:
Built one, it works pretty nicely but gives a fairly narrow frequency output. Some mucking with it will clearly be required.

lol yeah, I bet!  The real question is, are stealth miners built for use on your own computer?  Well.... no.  They're built for installing at work, at the library, etc.
You know, illegal theft of computer time.  People have gotten in serious trouble for that running FAH and Rosetta@home, and that's not for financial gain.

Yup, a couple times even.

That really depends on how you look at it.  A tool for sneaky USB drive installation and a total stealth miner is rather like saying that your easily concealed x-ray invisible switchblade knife is ok because it's just built to be easy to use.

I mean honestly, what do you think this is going to be used for?

Litecoin BotNet edition?

Maybe he already is an adult conversation?  That'd make him pretty special, after all.
Anybody can have adult conversations, not anybody can be an adult conversation.



Personally I definitely want ch/rs/whateverhe'scallinghimself in control of SC, it's hilarious watching him thrash around like a fish with a water shortage.

Assuming the first statement is true (which is quite the assumption), the second is hilarious!

It's ok to run a DDOS on alt coins now?

If I hadn't already left Eligius when I realized his wiki flat out lied about his payout methods (may have been fixed now, I don't know, I'm not coming back) I'd certainly leave now.

BEX did it (assuming he really did) by himself.

LukeJr used a bunch of other people in his pool.
That's a pretty big difference IMO.

They're both scum though.

Bout time for SC3, isn't it?

Could?  Almost certainly.
Should?  Absolutely not.
There are already longpolls every few seconds, GG would drop that to fractions of a second.  No thanks.

Capitalizing the first letter of the username fixed it, now it can connect!
Interesting, as the view-your-balances link doesn't care about capitalization at all.

Phoenix isn't very happy and doesn't seem to be delivering work very well, but I suspect that is an issue at my end.

Thanks for the help!

Made an account, but I cannot connector to it with a miner.
If I put the username into the page to check my balances it comes up correctly, but I get an RPC Invalid User error when I try to point a miner at it.

The female bit makes sense to me, it explains quite nicely why BEX expects other people to do all the work.

btc-e.com converts a number of them directly to USD.

Compile your own copy of ArtForz's minerd, with the proper SSE/AVX flags for your CPU.

The pot can call the kettle black and still be correct.  The fact that the pot is black as well doesn't change the kettles color.

Voted.

If march=native doesn't detect high level SSEs and/or AVX, it doesn't detect it.
Doesn't matter what the computer is being used for.

I tried march=native, it didn't do any better than just using SSE2 for me.
Specifying all the SSEs as well as AVX (I was using a 2600k) made a big difference.
