Cryptocoin Mining?

[wand3r3r]

Quick question. (PCI-E risers)

I have a PCI-E 1x to 16x powered riser, the power cord goes to my PC's power supply, but the cards power is coming from a second PSU. The card's fan starts now (it didn't when the 4 pin power adapter was on the 2nd PSU).

MSI AB and cgminer both can't see it. What's the issue here?

Note to self:
I shouldn't have bought basically the cheapest z87 board with 2x slots (I wasn't planning on going with 4 cards then) and Microcenter was sold out of most of the options at that time. The 2nd PCI-E 1x slot is completely under a video card so in order to use it I have to

Perhaps you need to do "How To Install A PCI-E 1X Jumper Wire" from http://www.gobitgo.com/articles/1001/How-To-Correctly-Use-and-Install-PCI-E-Riser-Cables/ ?

I was able to get my 2 290's and my 290x to all run exactly at 910khash. ................. My 290x runs at 950/1250
and my 290's run at 1030/1450

Now that's about as perfect comparison to show the difference between a 290 and 290X I've come across and may justify for some why the 290X MSRP's at $150 more.

I say put these cards under Water or buy the VisionTek CryoVenom R9 290 which MSRP'd at $550 (Not likely now when they become available) and put your rig under water and you will likely get well over a 1000k hash for mining with each card.

So question what happens to a coin when all the blocks are mined?

Thanks I gave that a try, it doesn't appear in windows/cgminer/ab still. I had seen that article a while ago when debating risers but I had forgotten about that jumper cable. So now I've tried with and without it.

Anyone else have similar issues?

Currency still continues. Mining still continues to secure the network. Blocks only contain the transaction fees, no extra coins. Money is moved around solely by transaction fees charged to send money.

Edit: So there is really no last block.

what card? 290?

Dogecoin (or something) is proving very profitable even for my lowly rig on middlecoin. My per-day payout is nearly double what it was a few days ago.

 

[wand3r3r]

what card? 290?

I tried to put a 290x on the riser. I have a couple cards in the case which work fine.

try a different riser, 290/290x cards are very picky about the quality of risers. Try shielding the riser with aluminum tape, I had to do that for my 290s.

also move it away from emi sources such as the psu.

if possible, put tahiti cards on risers and 290/290x directly into the full size slot.

Looks like my 5850 finally died. Sad day. I mined 1000's of dollars of BTC and LTC with it over the past 3 years.

Edit: Ran it at 100% load and 90+ temps for close to two years 24x7

Can you elaborate on the characteristics of the death?

Example: is there a big smoking hole in the circuit board, like this:

Or was there no visible signs on the circuit board, and the card is just not providing any video output (does the fan spin)? Or does it provide a video output, but it's just corrupted with visual artifacts and cgminer gives you errors?

 

[Z15CAM]

Aside from the blacken circuitry is that a blown bolt head? Ah! You don't need visual to mine -She's good to go.

Kinda reminds me what a nVidia Riva TNT looked like after a few weeks - LOL

No burns, when it is installed in the machine it causes all other cards to not be detected in Windows.

The Lottocoin exchange rate just quintupled today...

I suspect you have a VRM relay shorted to ground.

 

[gbeirn]

I suspect your VRM's are shorted to ground.

Well I came home from work one day and the whole house stunk like burning electronics. All my mining rigs were still up and running and no visible signs of damage anywhere (it took a while to look through everything) but once the machine with the 5850 in it rebooted that was it, never detected again.

Edit: I am going to hang onto that card forever though. Maybe make a nice case for it and hang it on the wall. Made me more money than I can count and help pay for all the other cards I now have. I love that card.

 

[Z15CAM]

A burnt VRM Relay (Coil) or short to ground in a VRM Circuit will do that. Something similar happens if you short out a VRM casing to ground when installing aftermarket heat sinks. This is a common mistake when installing a heat sink on the bottom VRM Module on the Reference R9 290/X as there is very little clearance to a Ground pin and shorts the VRM casing to the pin. Other then killing Video, the short usually does not damage the MB Bus nor Cards if you can locate the short (usually visible) and fix it.

Excuse me I should not have use the word Relay but a Coil where each VRM Circuit is a Transistorized PLL Voltage Regulator with a Coil. If the Coil is internally shorted you have to replace it; other words, the short is visible somewhere around one of the VRM Metal encased chips.

Good Luck on saving that Darling. I've got a few: an AGP ATi Radeon HD 9800XT & 2600XT PRO plus an EVGA GTX 280 that I cherish. There's nothing like firing up 95B or WinSE on occasions with a 1600 Mhz P3V4X Slot 1 and playing Duke Nukem, War Birds or Quake III - LOL

OC'd Tualatin in a slotket?

Yeah go DOGE go! Drop that LTC difficulty!!

Why would miners continue to "mine" the coin if they receive no coins? Dogecoin should be halving here in a couple months it looks like.

Much difficulty. No coin now. Wow.

Looks like it might be skipping on the bottom right now. Might buy back in.... need to check funds.

No mining = no network = no coin value.

They will receive some coins from the blocks that contain transaction fees. Every time you send money you must pay a little bit to support the network ( transaction fee). This gets included into blocks. For example right now, each BTC block found is 25BTC + whatever transaction fees were included so a blocks may be 25.4BTC total. Some pools keep the transaction fees, some do not.

This is the same with every crypto currency. It is envisioned that by the time all normal blocks are mined, the currency will be used enough that transaction fees will be enough incentive for people to continue to mine. Since no currency has reached that point yet, no one knows for sure.

The above is true for every currency except for NXT.

I read somewhere that DOGE would be 5% inflationary per year once all blocks are mined. I can't confirm this though.

Edit:

For the first time in awhile it looks like LTC is not corresponding w/ BTC fluctuations. I'm guessing that all alt coins are being eschewed for the new #3. Wouldn't be surprised if market cap exceeds LTC within a month or 2.

Doge is the obvious choice to mine scrypt, but holding.....? BTC, LTC, Doge or cash?

Yes this may be true too, some coins may not have hard limits programmed into them. Not sure which ones though.
