Some days I feel like a complete computer idiot... I cannot even burn a copy of BAMT to a USB that works!!!

Frank... any power readings for a 3x270 rig... wondering if it runs cooler and more efficient than a 3x270X rig.

atm, I only have 7950 cards in use and 270x on order, so can't help you on that one.  Looks like only one model posted to the mining hardware comparison list but without wattage info.  Nice hashrate though.  Hmm.  I am going to have a look at the technical differences between a 270 and a 270x.  Wouldn't that be neat if there was no real difference for mining purposes?

Litecoin mining comparison page shows no real difference between the Non-X and X cards, on all the R9s.  I was really tempted to buy the non-X version of the 270Xs, but the 3 fan gigabyte design is pretty slick.  Near silent, and stays cooler than a polar bear's toenails.

But considering the 2 fan gigabyte is only $179 on Amazon Prime, I might have to buy a few more cards in the next week or two.

I like the litecoin comparison chart, but I usually find it to be waaaay off, some results irrepeatable, details lacking, etc. I find better results in the forums.

24kilo, if you use windows, use the program I linked. Use a 4gb or larger stick to be safe, something fresh. It should burn without errors. If there are errors, it is likely the stick, slight possibility the downloaded file was corrupted on the way down. I would try another stick, then simply redownload.

I'm about to burn 2 more sticks right now, so I can test the 270x's which just showed up.

Preliminary 270x results

Setup: ASRock 970 EX4, BAMT 1.2, Cgminer 3.7.2

GPU 0 - The PowerColor AXR9 I was using before
GPU 1 - VisionTek R9 270X (link)
GPU 2 - Sapphire DualX 270X (link)

Here's where I'm at after like 10 minutes of hashing. I went with the settings from my powercolor tests (1145/1500, 24000, i20, g20):



The temps are a little weird because the first 2 are sitting next to each other, but the sapphire is hanging upside down over the PSU (kinda just tossed it there), so it's taking in PSU heat. Didn't have time to put in a riser setup.

Looks promising so far, but I'll have to put them on risers to eliminate heat issues while tuning (gpu1 was about to die because of it as you can see by the trailing hashrate), and then see what can be relied upon. Definitely over 450 I'm sure, but I would like to see over 480 stable. Power usage will come after this, I'm betting it's not above 175w/ea.

For another comparison, I know I already stated what I get earlier in the thread but here's a screenshot:



These are the Gigabyte R9 270 Windforce OC ones. I wanted to keep the project under $1000, but I didn't buy a hard drive or memory (had memory laying around and it's running BAMT from a USB stick). I'm not sure on the power usage, as I don't have a Killawatt, but from what I'm reading elsewhere, the highest I can find is max powerdraw is 180W each.

Here's a little mini album of the rig I built for it, I'm kind of proud of it but I didn't buy enough screws to make a spot for the PSU yet so I have to go back to Home Depot Sad:

Bejeebus... 24 MBs.  Someone down under is a baller.  What's the local slang for someone like that?


I figured I'd post here before I post elsewhere:

[WTS] GPUs - SOLD
https://bitcointalk.org/index.php?topic=411613.new#new

WTS 3 x Sapphire reference 7950s.  Mined and lightly used for literally less than 3 months.  My mining partner bought them and then never ran them.  They sat forever in the corner of his house not being run due to the fact that his place had no AC and summers here get into the 110+ range.  I took them to my place and ran them for like a month before I gave them back when he wanted to use them to game.

They come in the original boxes with I believe all the cables and such.

I would like to sell the 3 together to save on shipping.  Would like to get $250 a card, including shipping, so $750 for the 3, shipped.  Will take TAG or BTC.

PM me if you're interested.

My partner is bringing them by tomorrow, I can take pictures if needed, but I assure you that they are in VERY good condition.

-Fuse

Edit- In case anyone is wondering why I would sell the extra hashpower, it's because my partner has agreed to house our newer 270X rigs in his place.  He lives in a small bungalow style guest-house and he has to house the rigs in his main living area, so he wants to sell these to get quieter 270s.  I can't house equipment at my place because I am on a reduced power cost program has a maximum KWH per month limit.  The cards are great cards, they just don't fit our operation plans at this time.

So, .... I have some choices, and they look like:

1. 3 GPU, 1.4 MH/S, maybe lower wattage, and lower total cost. These R9 270 GPUs.
2. 2 GPU, 1.5 MH/S, (the one being offered by Mark at about 800 USD / 35,000 PHP)

And I don't necessarily have to get the ASRock BTC mobos that can do 6 cards too.

I've asked Mark a few times about his rigs, and he's told me a few times now that he's not ready to sell them.  I know you're more local to him, so if he's willing to sell to you and you can snag them, I would do that.  The R9 280X Toxic cards are legit, and the resale value should be higher than the 270s.  But in all honesty, the heat / noise reduction of the 270s would be worth it in the long run.

I'm going the route of the 270/270Xs from here on out.  I'll have to run more boards, but I really like the fact that while mining, these gigabyte cards are near silent.

I am going the same route... for me it is heat... it is 34C today... so about 100F... and I have to throttle all my 280X's to keep them running at less than 84C... if I can get a rig that runs natively 10C cooler... that is a huge gain for me to keep a higher hash-rate over a 24 hour period.

And so begins another torturous round of installing windows 7 (really should get into this Linux stuff!) .  As I mentioned earlier I bought a new MB today to enlarge the farm.  Had to get an extreme 3 as the 4's are unavailable.  Not a problem really as I've got a coolermaster 750W laying around which should be a nice fit for 3 x 270x cards.  Just need to get a 1x riser for the 3rd card as the extreme 3 only has 2 16x slots. 

Fortunately my family seems to kill at least 2 laptops per year so I'm never short of a valid windoze 7 serial...  Roll Eyes  If I run out, well, there are ways around it..  Wink  But it literally takes hours to install, reboot, install, update, reboot, update some more, etc, as I like to do a fresh install.  One of my 7950s has been pressed into temporary service to do all this, so there goes 650kh/s for several hours.

John,

I just got my order of risers in... if you need one... I am happy to loan you one till you get some more or sell it to you if you prefer... let me know... very interested in seeing how this rig works out... the heat is killing me today... I came home to find half of my miners shut down from overheating.

Thanks for the offer 24kilo but I'll be right.  I'll spend tonight getting the 3rd miner up to speed and then probably sit on it for a few days whilst I decide whether to go with 270x 2g, 270x 4g or just the vanilla 270.  By the time I sort that out and buy some new cards I'll have a few 1x risers courtesy of our ebay friends in Hong Kong.

It takes me an average of 2 hours to do a fresh install of XP and 7. It takes me another 30~60 minutes to stuff all the apps I'd need for office work. I buy an average of one computer desktop every month for my office.

The installations used are updated and slip streamed as of the previous month.

FYI

There is something not quite right.  The front-end is running extremely slow.  I'm looking into it right now.  There might be some downtime today as I restart services and such, but nothing extended.

This also might be a DDOS, but the initial charts are showing otherwise.  I'll check with the provider as well to verify.

Jackpot might take a little longer to process today, so hang tight.

-Fuse



9:18AM PST : EDIT- MINING IS DISABLED UNTIL I CAN FIGURE THIS OUT.  Manual and auto-payouts will still be processing.

9:41AM PST : EDIT- MINING HAS BEEN RE-ENABLED.  I am still investigating the issues the pool is having.

Things are back to normal.

There was an issue with a false double payout being detected, and locking the cronjobs.  I've resolved the issue, and the pool should be working properly now.  I will be watching it through the day to make sure.

I will process the jackpot tomorrow in case there are any issues with the DB records.  I just want to make sure everything is squared away before I do the processing.  I hope everyone understands, and can wait a day longer.

24Kilo, you might be interested, but I figured I'd ask openly in here just in case...

I would like to sell my 531145 Coinye for Earthcoins.  If anyone is interested, let me know.  Not sure what the conversion is, but I'll research offers.  Just PM me.

Yes... I'm watching threads right now.  Will be watching the main tagcoin thread mostly, so if I don't respond here, you guys will know why.
