The website is back Smiley
UPDATE: website is intermittent as of 9am (PST)

It does look like the pool took a hit last night 7p, but it bounced back by 8p.

I left my miners connected and it's been doing just fine.
It does look like the pool lost about hash it's hash rate since the dip.

The new bootstrap theme combines the desktop and mobile theme into one that can be used for the full pool experience from any device. 


Please report any issues with the site. 

Also, do you have skills on website theming?  Any help or donated work is much appreciated.

+1 for extended login timeout.

Many of the other pools log you out after say 5 minutes of inactivity. 
That makes it a total pain to check on your miners if the pool happens to be your only way to do so. 

I LOVE the long logout times Wink

Hi again Marty,
My miner seems to be happy swimming in your VTC pool Wink  Over the last 15 hours I'm averaging about .25 VTC per hour.  I've read that you really shouldn't evaluate VTC by the hour, a longer time sample is needed to get a more accurate indication of your miner/pool performance... but I only got hours at this point.  I will be running for days so we'll see if the numbers improve.  At this rate I'll be making 6 VTC/day, at the current exchange rates (VTC 0.00276, BTC 567) that would be $9.38 USD.  Unfortunately I live in LA, so power is a little spendy... my rig is running 4 Gigabyte r280x GPUS (undervolted) consuming a total of 1100w... which costs me about $4.42/day.  So currently, if I cash in as I go, I'll be raking in $5/day Smiley  Hey, if I found a $5 bill on the ground everyday I'd pick it up and feel lucky!  I would guess most people are hording their VTC in hopes the value skyrockets, but I'm trying to get ROI first.

You new webpage is looking pretty fancy.  I like that it's now different than all the other VTC pools.

Question about the Stats Graph:
Are the plotted data points the average of the hashrate over the last hour, or just what the hashrate happened to be at the sample time?

Suggestion for the Stats Graph:
The Both graph is not really useful as the pools hasharte is so much larger than mine, it fits the height to the pool max, and my hashrate is basically a straight line at the bottom.  Would it be possible to simply overlay the two graphs (with their original scales) in the Both mode so you can compare peaks and valleys?  Sure the units would be confusing, but in the Both mode your really looking at how the graphs compare and you can always switch back to individual graphs to inspect the unit values.

Comment on the Overview>Round Information:
Looks like the VTC 24 Hours Estimated Earnings is just a duplicate of the Hourly


Question on Miner Performance:
Is 1400kh/s average good for a rig of four r280x GPUs... or is there room for improvement with further tweaking?

Now if I could just find a block...

Hi Marty,
Just joined your pool this morning and so far I'm impressed!   Not necessarily by the pool's performance (yet... I only just started) but more by the communication you offer here on the forum and on your pool's dashboard.

I started mining back in November and learned early on that coin switching would consume my life.  That's when I found Middlecoin... at the time a growing multipool with good payout and a community.  Unfortunately the pool operator was not very forthcoming with information and left his miners in the dark more often than not.  Looking around, I found another up-and-coming Multipool called Wafflepool.  This one looked really good in that the operator was totally responsive, active on the forums and actually seemed to care about keeping his miners in the loop.  However, fearing the Gridseed... I decided to explore VTC and other asic-resistant coins.  I've been having difficulty finding a good community for VTC... like what we had over on Wafflepool.  I joined a few pools to keep my miners busy, and the first few days it was about 4x what I was making on Waffle Smiley  Then things started to slow down... I tried to contact the pool owner but there was no forum and they never replied to email Sad  A second pool I mined for just disappeared with my coins... so I've been investigating p2pool and running my own server to connect to... but the research has been slow.

So... all this to say, I'm encouraged by the possibilities it appears your pool will offer. 

Let's find some blocks!!  Wink

Just a heads up guys, but WAFFLESTATS will be down probably until morning. I needed to upgrade the AWS EC2 instance and my instances keep getting AN INTERNAL SYSTEM ERROR HAS OCCURED whenever I try and launch a new instance and/or request a spot instance. What was supposed to be a simple: Backup database, stop existing instance, start new instance, reattach database turned into an hour of SYSTEM ERROR SYSTEM ERROR SYSTEM ERROR.

Sorry. Undecided

Annnnd, we're back. Sorry about that guys. Also, huge update coming tonight or tomorrow. :-)

WOW!!  AWESOME!!

Nicely done MisterWil.  Woke up to a brand new WaffleStats!

I don't got much, but listen for a *clink* in your tip jar today  Smiley

one word:  RAILS

This is a new one for me.  Either I got lucky last time I built my SLI windows machine, or the cards weren't power hungry enough compared to my PSU... but in this case, it's all about the RAILS!

When I originally connected up my wires I figured given the modular design of the connectors, there was no way to wire it wrong.  Two GPUs per PSU, red goes to red.  Being a little OCD, I liked the look of VGA1 and VGA2 being populated in each PSU... FAIL!

Moral of the story... put one GPU per rail... in my case it was VGA1 & VGA3 (or VGA2 & VGA4) on the PSU.

Ugh!  No matter... I'm just glad it's solved.  Hopefully my public humiliation will help future miners avoid the same pitfall.

So you can run one card at a time, but not both at once? Sounds like a PSU issue.

Crazy!! As much as I don't want it to be a PSU thing... it might actually be?!  I need to investigate more, but here is what I discovered (thanks to your prompting).  If I put one GPU on each PSU, both will run at gpu-threads 2.

Here are the Watts:

PSU#1 (numbers include LCD)
54w idle with MB, CPU, 2 GPUS on motherboard, but powered via 2nd PSU)
105w while mining at gpu-threads 1 (both GPUs powered by 2nd PSU)
326w while mining at gpu-threads 2 (one GPU on each PSU)

PSU#2
246w while mining at gpu-threads 2 (one GPU)

For the life of me I can't fathom how these brand new 750w Gold PSUs can't handle 2 GPUs who's combine load is under 500w?!

Next I'll start playing with cords and VGA PSU slots to see if there are some magic combinations.

Can't get gpu-threads 2 working on multiple r280x GPUs *SOLVED*

I'm building a new mining rig but can't seem to get past this problem.  Each GPU can run with gpu-threads 2, but if both are set it will only mine for a few seconds before the video signal fails and the GPU fans spin down to idle... the system then requires a reboot.  I've tried various Catalyst drivers, litecoin_bamt installs, powered risers, GPUs mounted directly on the MB, even flashed their BIOS to run a lower voltages.  Together, they pull under 500w before it crashes... no visible power spikes or other oddities.  I'm running out of ideas, so I'm willing to try just about anything.  In fact, even if I've tried your suggestion in the past, I will try it again and post hard data where applicable to best document this problem (and solution hopefully).

Here are some specifics on my hardware:

I used this guide: http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/
MB: MSI Z77A-GD65
CPU: Celeron G1620
RAM: Kingston Hyper X Blu 4 GB
PSUs: 2 x EVGA SuperNOVA NEX750G
GPUs: 4 x GIGABYTE GV-R928XOC-3GD rev2 r280x
I've posted about this problem in another related thread, but the replies get lost and so does the momentum for finding a fix.  I'm hoping I will be able to update this thread with the large bold SOLVED before the weekend is over Wink

Related thread I posted in... (Most of the suggestions centered around power issues):

I have also posted this on the litecointalk.org forum and will update both if a solution is found:

Hi all,
I tried the pin short on two 1x slots of a Asus A8N-E with no luck.  The computer doesn't boot or even give me the first beep... no video signal.   The fans, keyboard and mouse get power, but no joy.  Is there a certain BIOS I need with this MB for the pin short to work?  I can't get more than one card workin in this old box Sad

Any help would be appreciated!
