    Don't I Know You Guys?

    I remember relic. I'm still doing the old f@h on an AMD 4p and HD 7970s. Recently PPD had been majorly cut but this hardware is due for replacement. If I stick to folding at home the next hardware will be GTX 980 Ti GPUs or something 14nm.

    Make this Christmas [H]ard to forget

    Nothing much has changed for me, I haven't updated my FAH setup in at least a year. I'm running the same 4p and triple HD 7970 system as last winter and still getting good PPD.

    Change in BA requirements

    I think the announcement could turn out even better than before, bigadv machines becoming obsolete was a bad idea. Too bad VJ didn't wait for his new PR hire to word it a bit nicer than a termination date for bigadv. Really it could be more of a merging of bigadv and SMP if they set QRB right...

    Change in BA requirements

    What if the fix is to get rid of SMP and move all WUs to a point scaling that matched bigadv? Fast machines would still be rewarded throughout an increased QRB and the current bigadv WU would only be assigned to machines that had enough RAM and were returning lighter WUs fast enough. That way...

    Change in BA requirements

    The threshold is not arbitrary, it helps Stanford control how much research is being done by projects that use bigadv WU vs standard SMP WU. Some WU benefit from the fastest machines but Stanford doesn't want a large fraction of their network power being donated to these projects because the...

    Change in BA requirements

    That sounds very positive. The main remaining issue is that because the "# of cores" metric is so weakly tied to performance there is still no indication at all about how fast systems will need to complete WUs to make deadlines and stay in the ppd inflated "top 5%" category. When Standford works...

    Change in BA requirements

    F@H drama is a pain and you are not helping. Stanford's views seem to perpetually differ from those of the enthusiast donors which is unfortunate but the layers of forum moderators and representatives in between seem to only stir up disagreement. Everyone can read what Stanford says and either...

    Change in BA requirements

    I like the first long term roadmap and communication points. If I'm buying a new piece of hardware for the project the three factors I look at are upfront cost, power usage, and the "usefulness to the project". The first two are easy to track and don't suddenly change on me, it would also be...

    Headless AMD Overclocking

    One trick is to use VNC such as tightVNC to access the system, Windows Remote Desktop messes with GPU drivers while VNC has no effect. Teamviewer is great for remote access over the internet, I don't know if it works well for folding. Another trick is to right click on the desktop to change...

    FPGA Folding

    Seems the FPGA chip alone is around $7000 if you want to solder it on yourself, I think the dev board could be cheaper than that though since the goal is to get people trying out the tools.

    Altera's new tools write the Verilog for you. Paste in your OpenCL functions with some modifications here and there and at the end Altera produces the Verilog needed to run the functions on their FPGA. Basically it automatically create a custom chip architecture for you with advanced arithmetic...

    Linux Core 17 - situation in June 2013

    Does anyone know GTX 770 power consumption while folding these units? HD 7970's seem to get around 100k ppd while pulling about 160 W from what I've seen.

    AnandTech Supermicro quad 4650L review

    I put a comment in there somewhere a few days ago. Getting a 4p humming, even for folding which is very multithreaded, takes a bit more than Windows and some software designed for single processor systems.

    On P8900 I think there was a noticeable performance drop when I had the memory down as far as it would go in Afterburner on my 7970 (600ish?). I have memory back at stock now.

    G34 chip choices.

    If you are finishing more than one WU a day on average the you can hit 1M ppd without seeing 1M points per WU.

    12Core 63XX better than 16Core 62XX??

    But with fewer cores you should be able to clock them higher without straining motherboard voltage regulation or cooling. *Assuming AD ES can be overclocked.

    I have them on a motherboard that allows for an empty space between each card in an Antec Eleven Hundred.

    Here is my account. 4p 6128 at stock folding bigadv under Linux. That has been the only points to my account except for a couple WU on HD 7970 last month. Points are back up to where they were when I built the rig in Jan 2012. The one dip in early 2012 is from the Chimp Callenge.

    Intro, 1 week folding, lots of lessons learned

    I built a similar system to your HD 7970 rigs. I have a Gigabyte UD7 motherboard I found used to allow me to run three Gigabyte cards with that spacing. With a very high workload (LTC mining) the fans on these coolers barely run fast enough at max. I have 4x 2000rpm 120mm fans on the side panel...

    OpenMM 5.1 version of Core 17 released to beta

    I really want to see power consumption numbers for this core. Litecoin mining can push my HD 7970 to 55C above ambient while running this core I see 29C above at 100% fan. That should mean power consumption is at about 60% of mining. Edit: It looks like my client was glitching there. PPD has...

    My 3 HD 7970s really like this config for cgminer. Averages 2.006 Gh/s up from 1900ish with GUIminer. Clocks are at 1160, 1090, and 1080 with stock voltage or lower. Memory is at 675 because that is the minimum in Afterburner. Bitcoin and LTC profitability are fairly close right now so if you...

    Bitcoin Discussion Thread Part 2

    Now is a fine time to build a 7970 or 7950 rig. At current prices you get about $50 a week from each card mining and when that is over, folding and many other DC projects run great on AMD cards. The game codes are going for about $20 each on the FST forum so that is another $40 off each card.

    Most newer cards disable voltage control. Many brands disabled voltage control on model numbers that had it at launch. From what I've seen there usually isn't any easy bios update to get voltage control back.

    Core 17 updates

    I wonder if he could calculate how many flops the software is able to get out of these GPUs? HD 7970 does 4 trillion operations per second, I think it would be interesting to know how much of that performance is actually getting used.
