  1. I had it beaten on chiller already, so this gen seems a little bit faster, but not by much. If my efficiency is not too bad, then one would need 7200+ for sub 4 min on AMD, perhaps it's possible with some of the CPUs of the top guys. I'm not sure how big is the difference between validation and Pi as ZenStates was limited to 70x max multi and I hit that pretty easily Got beaten by my own tools, but I will try again next time. 74x seems to be the highest supported multi according to AMD's RyzenMaster. PS: First one on the bot has 74.75, so maybe 74 is not the max - I don't really know.
  2. I have removed the lower limit. The steps will be stupidly small (0.05MHz), but hopefully it works. I'm not sure what is the lowest supported frequency by the integrated PLL in nForce2, but you can try. Lowest multi should be 3x, but not sure on which generation. https://github.com/torvalds/linux/blob/4cee37b3a4e68c42b867c87a6218e11bc571ba66/drivers/cpufreq/powernow-k7.c#L78 NForce2Xtreme-v1.1-beta19-mod.zip
  3. I have tried and fclk and mem freq didn't matter for the cb. Today, with a remount, I was able to go lower in temps, but didn't have LN2 left to actually run anything. The contact footprint on the pot seemed perfect this time.
  4. You need a VID mod to effectively bypass OVP - by setting a higher VID you lift the OVP trip point to higher value.
  5. It's not possible to change memory timings runtime (within Windows) on AMD AM4/AM5 systems. Userspace programs don't have the privilege level and although you can write the value in the register, it does not get applied. It it was possible, I would have added that functionality into ZenTimings.
  6. I can run 6600, but not for y-cruncher, at least not with "tight" timings. Seems to be limited by the locked mem voltage, the cheaper memory (?) and the score probably should be better if I had tREFI. Maybe the controller is to blame at 6600 for y-cruncher, but I could not get it to run reliably. I have nothing to compare with, just one of each - cpu, motherboard and memory kit. The CPU looks like a good one with very small difference between both CCDs - around 50MHz, maybe good for MT benches. Not sure how common is that for this gen, the difference was usually larger for previous gen. Will have to see what it does with LN2.
  7. Didn't have mich time. This combination was giving me best results in 7zip. DRAM voltage is limited and the board has only one bios. Don't think I can tighten timings much more at 6000.
  8. Let me start. I don't have a 5GHz run and the efficiency is probably way off, plus timings might be plain wrong, but anyway... I only had 1 day to play with the system and not sure when will be able to do again, but hopefully soon. I was able to beat the current AMD top score as well: https://hwbot.org/submission/5125310_
  9. That's a catch, indeed. I was clueless why my score doesn't show up.
  10. Great deal, indeed. However, the usual question for most of the 939 CPUs is "if it scales with cold". A good water/air chip doesn't really guarantee a great result on LN2. Higher multi cpus have a better chance though, before hitting the cold FSB limit, but everything depends on the CB. This, for example, is a dud air chip, that could have been easily discarded, although it scaled massively on LN2 due to very good CB (-90 to -100C range, which I think is very rare for Venice): https://valid.x86.fr/8fed9t I don't reject any s.939 CPU anymore based on ambient tests only.
  11. Maybe back off the volts a little? It seems slow even on inefficient board, indeed. Perhaps the result will be better with a little lower clocks? PS: VCore seems too high for what I've seen (feel comfortable with) when benching K10. On my older screens with the 970A-UD3 board, the vcore under load is much different than what cpuz shows idle, something under 1.9V, because that board has an enormous vdroop.
  12. That's true, however the same applies for "ambient" water cooling. Ambient is not a definitive term. Someone's "ambient" might be below zero (with the rig outside), then other people are in the summer already with degrees over 30 (Celsius) during the day, so it will never be "fair" for everyone, despite the good intentions and idea. If the verification is done by a rig pic only, then good luck verifying anything. At least Alby (@leeghoofd) has shown his "ambient" clearly, can't say about others though :p
  13. I'm a little confused as well. Currently, 25-30C degrees daily temps here and my ambient is 24 right now (no AC). If my only cooling on the bench table is a chiller (with controllable temps), then: 1. Am I allowed to participate at all? 2. If yes, then what should be my chiller set at? 3. Am I allowed to go down in temperature as long as cores are still reading positive temps? Thank you! PS: There seems to be a thread about the competition already:
  14. By HTT he means the refclock/fsb in conjunction with temperature. Decreasing the temperature to increase core clock (while using a higher multi and/or voltage) will drop max benchable HTT/FSB, but judging by the current score you have a nice headroom left.
  15. Just wow! This is enormous amount of work done to the board, you deserve it! Digging the voltmeters, somewhat an improved version of my own one PS: Too bad the card doesn't look that good, especially on the mem side, would have made a bigger difference.
  16. I've ran a K6 on LN2 just once and mine had a CB somewhere around -80 IIRC. Not sure which one is more common
  17. Great one! I can't fight back, my 1800+ is long gone, it was pretty much beaten up when I got it anyway. Cascade is the way to go on s.A. You can still gain a little with LN2, but you can run for "indefinite" time with cascade.
  18. Depends on the board. Crosshair VI Hero, for example, supports Bristol Ridge in all bioses. If you leave Performance Boost to "enabled", then the boost multiplier (x36 in this case) can be used. Could not find a way to overcome that limit on "E" chip, but the same model without "E" has the multiplier unlocked above max boost multi.
  19. I have provided some more details as a comment under the submission in question. Don't think it is an intentional cheat and doesn't deserve bans or something like that, just doesn't belong to the LLC competition. It would be plain stupid to still show the actual clock in cpuz if trying to deceive others. It might be a simple mistake with setting 100.6 instead of 100.06 bclk, although I don't know what is the minimal step that Asus board allows. Benchmate version used seems to be the same as in my test run, but for some reason doesn't show the maximum effective clock - might be due to different win10 build (older) or the benchmate build itself? PS: The score is "impossible" with the claimed clocks, unless someone finds a magical tweak. Have to try newer agesa though, there might be slight improvement in performance.
  20. Sorry, but I don't think this score is eligible for the competition. The bclk is clearly altered. The version of BenchMate used is not showing Max Effective Clock for some reason. If you load Windows at e.g. 100MHz bclk, open BenchMate and then increase bclk, the "Max Core Frequency" does not pick up this, but "Max Effective Clock" does. FCLK, UCLK and MCLK are read from SMU power table and they are always reported on 100MHz-base, regardless of blck set in bios or in Windows. CPUZ clearly shows the increased bclk, also one of the timers is skewed. I have made a similar test on whatever Windows install I had on the SSD and got 2nd place easily with a single run. Boot bclk is 100.0625, then increased to 100.63 in Windows.
  21. They boot, but don't know how good they work. Unify-X still supports them in the latest official bios on the site. No official support announced on the site, but the modules are clearly there and I've tested 1800X and 1600AF on some of the older bioses. IIRC there were some options missing and the support is basic.
  22. It's in the human nature to explain things you don't understand with something else - aliens, god, cheaters, etc.
  23. What's next, dual-core Richland with a disabled core competing in single-core rankings? PS: Great frequency!
