    More AMD love and AMD 32 mil WR

    AMD FX-8350 Super Pi 32 Mil 9m19.828

    The last three months I have been competing in the Pro Cup Q4 contest. I tend to bench for me, and my results are for my enjoyment and pleasure alone I hardly ever submit scores. I like the tweaking side of things, the OS set up for specific hardware combinations is a bit of a hobby. My team mate for this contest, 8 Pack, is an exceptional over clocker, he can get an extra 100MHz out of hardware that others can not. He also benches to have the world’s top scores and is constantly posting top score. So you could say we would make a good team because of those differences, and we do.

    You can go have a look at his impressive results here.



    However Ian is more of an Intel kind of guy, and I am a bit of a Fanboi about the processors and the brand. Add to that Super Pi 32mil is the Blue Ribbon of 2D benching and I was hooked when Ian asked me if I could do that leg of the Pro Cup.
    This is a story about that journey.

    This journey would not have been possible without one man’s brilliance. The Stilt has single handily changed the landscape of AMD benching. Without The Stilt and his body of work no sub 10 minute Super Pi 32 mil scores would be possible I do not think. Thank you sir and long may you continue to explore.

    You can read up about this HERE

    The set up.

    AMD FX8350 8 Core Processor
    ASUS ROG Crosshair V Formula-Z
    Bios 1701
    Corsair Dominator Platinum
    PSU Enermax
    CPU LN2 Pot – Custom built by Thomas Keating Ltd.
    OS – Windows XP Pro (SP3)
    Hitachi 1TB mechanical hard drive
    LN2 Memory Pot

    The first thing to do when going sub-zero is to make sure your motherboard can take the cold and survive an extended period of benching.

    This is what my boards look like when I start to prep them. I paint them with liquid plastic to make them condensation proof. Much cheaper than Liquid Electric Tape and has the same conductivity factor as LET.

    Artist Eraser is the next part of the process, I block up the one set of dimm slots.

    Next is the paper towelling. Here I use the industrial paper towel rolls and will use an entire roll in a week when benching different platforms. So I buy them in bulk, pallets of 48 in fact. Makes my wife go crazy because out house is really small.

    There is a whole heap of stuff that goes on before any good score is produced. All most folks see is the finished product, the score. That is just part of the story.


    What you do not see of often hear is the days and weeks that get eaten up in the binning process, in the testing of OS phase once you have found two or three good processors. And the other hardware binning that is needed too.


    Let us start with the processor. I binned over 20 CPU’s for my first good processor. Then an outstanding bencher from Germany, Roman came along with his first CPU and benched at over 8GHz blowing my submitted score and all my backups out the water. That meant going back and starting all over again. This time I tried not only 8350’s but samples of all the AMD processors that were available. Yeah that includes the APU products too. Until finally I found one CPU that would let me bench close to where he was able to run 32 Mil. This process of searching and binning had taken nearly three weeks.

    How I bin. I set up my motherboard, the Crosshair V Formula-Z, with a single profile that includes voltages for the processor and memory. Then with the multi at 20x and set a high FSB of 300 I expect each CPU to boot into OS at 6GHz with all cores active. I then use TurboV to increase the multiplier by one each time, without changing any of the other setting values. I keep the two best CPU’s that were able to clock the highest at that set voltage. This is repeated time and time again until that one golden CPU is found, or not as is the case most often.

    Different CPU pots were tried to see which was best and in the end I went with the pot that Trevor Walker technical director of Thomas Keating Ltd designed and fabricated for me. The pot is fabricated from 12mm copper rods and a solid round bar base and not machined from one chunk of copper, held together by cryogenic glue. These guys make stuff for the aerospace industry. Love your work dude I owe you a pint big time.

    What you may not know is that I also bin motherboards. I tried with the Crosshair V Formula and the Z versions, 12 in total. I kept three of those twelve as performance was better by some measurable mark in Super Pi efficiency. One CHV and two CHVZ boards.

    Just some of the boards, I am too ashamed to show you the others as they are just all over the floor. I am not a tidy bencher at all and tend to take over the entire downstairs area.

    The same goes for the memory by the way, sadly I damaged my best set of memory two days before producing the final result, my back up for the contest otherwise I am sure I could have improved on the efficiency of the run. None the less I did have backups and had done the preparation work in determining what worked and what did not work.

    The whole process of the contest was heaps of fun and stress in equal parts. The first few sessions I could not get the one board and processor to run dual channel memory.


    9.42 run.

    I was able to improve on that run with a different board but still not get the pesky dual channel to work. And that was costing me big time.


    Finally I got the combination right, only to damage the memory sticks as I said earlier.


    I am quite embarrassed to say that the excitement got to me that day when it all clicked into place. You see I forgot to set CPUz to read the correct core. For those of you that do not know with AMD you can overclock a particular core higher than the others. PSCheck 3.4.1 is the application that allows you to do this, and you can change multiplier of one core. I then use TurboV to change the FSB. Thing is CPUz reads core #0.

    So on this run below I was actually benching at 7990 MHz according to my calculations, give or take a 10 MHz. Not sure I made 8GHz benchable but must have got darn close.

    Now that I had a level that I could bench at I saved the profile in my TurboV and started to work on my memory. At this point I realised my benching kit was damaged and had to turn to plan B. But at least I had done most of the hard work.

    My best run and the product of three months’ work, over 600 litters of LN2. And speaking of numbers, I must have run the benchmark at least 2500 times over that 3 months. It was all consuming and I had very little time for any of the other things that were going on in my life at the time.

    This is the method I used.

    Boot into OS
    TurboV and Super PI in the start menu

    Get Super PI 32 mil ready to run

    Set frequency of strongest CPU core
    Run stop bat file
    Wait for 3 to 5 minutes and do your wazza
    Wazza is 3 x the size of my maxmem well spotted Arne.
    D --> C pause 10 seconds C ---> D pause seconds D ---> C 45 seconds pause.

    Run benchmark.

    Repeat over and over again changing FSB and hope that it does not fall over because that mean new OS. After any blue screen ditch the OS and clone from ISO found that a blue screen or any freeze impacted on the times measurably.

    In conclusion special thanks to Mansfield Cryogenics for their willingness to drive down South and replenish my two Dewars, and of course ROG for the great motherboard design. Sadly I cannot thank AMD as I had to buy all my own processors and took a huge hit selling them on. But hey that is the price you pay for the sport you love.

    this is awesome my friend! Really crazy awesome. You like AMD maby emore than me . Your wasted time with binning and preparing... I have few question for intereting.

    Whats is this CPU batch? Do you know it?
    Did you found some difference between boards in max clock with the same voltage?
    Can you test thius CPU with some highend "air" cooler or allinone liquid? How high can it with 1.55V (Cinebench and Superpi+validation)?


    Awesome result and congratulation again for hard work and enthusiasm for AMD+ROG . And for very nice article to readings .

    Cheers - yeah I am a big AMD fan from many years now. They have a factory in my families home town since 1999 and I was lucky enough to be part of a project (research team) for 18 months at Fab 30. Project was cancelled Not my fault. But I have always continued to have an affinity with the brand.

    Binning - I do not think of it as a waste of time, binning is in my view as important a part of competitive benching as OC or tweaking is. You either bin or buy a golden chip for a high price. We see it happening all the time, guys selling Intel 4770K that can do 7GB for $3000 a few months ago. My way is cheaper for sure but time consuming. I am lucky that I can sell most of my discards on to system builders so I do not loose too much money.

    FlanK3r I bin under cold, I do not mount the CPU pot a very heavy solid copper pot, but I get it down to full pot state and test both IMC under cold as well as max core frequency and FSB at 1.66 volts. The best processors are then also binned for HT and NB frequency. The dream is to find one that has the best of all those aspects in one CPU - but so far I have not been lucky.

    The CPU I benched in the final run was a retail CPU - 1252PGT. This CPU did not like voltage as much as some others, and scaled really well with cold. The best clocks were achieved under 2.000 volts - it is a pity that I did not have the right core enabled in CPUz as I have no way of knowing if I actually benched over 8GHz for the 9.22 run. Which for me was part of the gaol I had set. I think I did, by doing the maths with PSCHECK and the FSB I think I was well over, but no CPUz so can not claim it. But I was never able to get the FSB that high with the memory timings I wanted to use again. In fact I have not been able to get over 300 FSB and that 27x multi to work together again. I had set it with PSCHECK and upped FSB with TurboV in the same way as before but no joy. That is how hardware goes I guess.

    Boards - Hmm this is an interesting one. I found that the Z boards were very good for memory and that made a difference in the end. The CHV was a little better with the top end clocks on most of the CPUs that I benched with but so small amount that the better memory clocking made it worth while going with the Z boards.

    I have done no air or water cooling testing at all it is so much easier to just put a 3.5 Kg lump of copper (my binning pot) on the CPU and get on with it. Easy to swap out just lift it up with the CPU still attached when done (frozen to the bottom), put the next CPU in the board and carry on.

    Very cool, indeed!

    I've been following 8 Pack's awesome work for a while and you already know I'm a fan of yours, but we need video. The pictures and the narrative are great and all, but...
