  1. Thanks for your experience! Did you manage to clock your memory higher than previous generations?
  2. Hi all, I was wanting to get some census on anybody running Ryzen 3000 series, preferably 3950X or at least 3900X on a X370 Asus Crosshair Hero VI. How has your OCing experience been, did you have to tweak any settings in particular to get memory or inifinity fabric to be stable? (stable being, for example 8 hours in Realbench stress test). I was able to achieve a stable 4.3 GHz rather easily with just offset voltages, but as soon as I even look at the memory frequency or timings the stability just goes out the window. My BIOS version is 7601
  3. It is mainly propylene glycol. However there may be some ethylene glycol in it too, exactly what ratio is unfortunately anybody's guess. To be on the safe side, it should be treated the same as automotive coolant.
  4. By case fans I assume you mean radiator fans. You've now unoptimized the liquid cooling setup since the BIOS has no idea of the fluid temperatures and ramp up the fans according to the CPU temperature by default. This is stupid with liquid coolers since you don't need to increase fan rpm unless if the coolant temperature increases. If you were to do this sensibly, taking the functionality of the S36 into account, you would: 1. Plug all radiator fans into the fan hub on the S36 2. Plug in the pump fan header into the CPU_FAN header 3. Set CPU_FAN header to be 12 V DC, Full speed mode, whatever in the BIOS that gives a constant 12 V to the pump You're exchanging a lot of functionality for just being able to see the fan rpm in BIOS which in my opinion is super dumb.
  5. The BIOS is reporting the pump rpm, which should be set at max speed (12 V constant, DC mode) for AIO pumps. The fan speed is controlled by the AIO itself reacting to (probably) fluid temperatures and so the BIOS will not show the fan speed, but this is intentional and should be left this way.
  6. I always do 8 hour RealBench stress test to check overall system stability.
  7. Yes, it was at 20 %, then I tried 0 %. Neither was relevant. I also cannot be reliant on Windows only software since I half-half with linux. So would really need a BIOS level solution.
  8. So yes, after tinkering it looks like Zen2 only has one P-state (P0) so while setting the P0 to 4.3 GHz and VID to ff, it achieves the 4.3 GHz overclock since there are no other Pstates the CPU doesn't downclock. Any other suggestions are welcome on how to get the thing to downclock on idle
  9. So i managed to overclock by pstate, but there was only p0 and im not convinced its clocking down.
  10. Hi all, Just finalizing my overclock of the 3950x on my Crosshair Hero VI (x370) motherboard. I remember on Gen 1 when I was overclocking my 1700, there was this thing called Pstate overclocking so that the CPU would still downclock when idle, is this still a thing for Gen2?
  11. Not saying either is better since I haven't used the VPP775 V3, but I did want to raise the point that the VPP775 V3 is no a D5 and is not made by Laing/Xylem
  12. So been playing around with the 3950X (installing it was supposed to be easy but I dropped a washer and so it was more complicated than it needed to be....). I've got an all core overclock of 4.3 GHz, using offset +0.325 V in BIOS. It's a bit weird since it doesn't seem to reflect volts in HWinfo but for whatever reason the temps are better than Auto, so I leave it be. During Realbench stress test temps are in the 80-85 ish. Fluid temperature at the moment equilizes at 41 degrees with radiator fans at 1100 rpm. I've installed a "temporary" spot fan in the PC to get strong airflow over the VRM heatsink, this keeps the VRM temperature at 58-60 degrees during Realbench. Without the spot fan, the VRM heatsink gets to around 80 degrees ish, not catastrophic (for VRMs), but hotter than I would like. So this fan may be here to stay. Thankfull as a Noiseblocker fan, it is not very noisy. At 4.3 GHz, Cinebench R20 scores are just below 10k (9920~9980 ish) however this is with Stock RAM. However enabling a RAM overclock looks like its not going to so straightforward with the X370 board and my quick attempts did not look very stable. I guess this would not be the case with a decent X570 board, but I only have what I have, so we'll see Picture to come....
