K900 | In reply to @atemu12:matrix.org K900: If you do stress -c 32, is your 7950x3D also up against 89°C and only at ~4.2GHz? Hold on, I don't have stress-ng, but I might have cinebench | 10:07:49 |
K900 | So yeah CB R23 multi-core is getting me to the 89C limit | 10:18:52 |
K900 | But I am getting better clocks | 10:18:56 |
K900 | 4.7GHz or so on CCD0 and 4.8-4.9 on CCD1 | 10:19:04 |
K900 | I can probably get it a bit higher with a more aggressive curve optimizer | 10:21:08 |
K900 | I'm currenly running -10 all core | 10:21:12 |
K900 | And I know this chip can go to like -20-25 | 10:21:46 |
K900 | But I've seen a few weird glitches that I can't attribute to undervolting but also can't NOT attribute to undervolting | 10:22:13 |
K900 | So I've been running it a bit more conservative | 10:22:22 |

Atemu | In reply to @k900:0upti.me But I am getting better clocks Damn, indeed if I up the fan speed of CPU and case, it clocks quite a bit higher | 11:30:13 |
Atemu | Already at 4.3-4.4 but my case is still rather hot from the stress test I just did | 11:30:35 |
Atemu | In reply to @k900:0upti.me Hold on, I don't have stress-ng, but I might have cinebench I'm using regular stress I think | 11:34:29 |
Atemu | Hmm, perhaps my NH-U12A actually isn't good enough for the 7950x3D? | 11:46:46 |
Atemu | After letting it cool to regular idle temps, it's almost at 89°C again with an all-core load | 11:47:21 |
Atemu | And that's with full fan speed and for both CPU and case | 11:47:44 |
Charles | Zen 4 CPUs run as fast as they can and try to hold 95C | 15:14:37 |
Charles | so that seems pretty much normal | 15:14:51 |
K900 | 89C for the X3D parts | 15:15:43 |
Charles | ah well there you go then | 15:15:58 |
