**** BEGIN LOGGING AT Tue May 12 03:00:16 2020 May 12 05:57:58 elvispre: it was never 100% fully stable and it showed when I was running JaMa's OE benchmarks. Got new ram from Corsair but seems similar issue.... Testing them 2 modules at a time now with memtest86+ to see if there's a faulty module May 12 05:58:29 JaMa: doing the memtest now to make sure all modules are OK, afterwards might try that May 12 09:31:21 OK seems I'm able to narrow it down.... May 12 09:31:49 4/8 worked OK while testing 2 modules at a time May 12 09:32:23 When I tried modules 5&6 got errors May 12 09:32:31 Now testing 7&8 May 12 09:32:44 Then will try 5&6 one by one May 12 09:32:56 So seems faulty module most likely grrrrr May 12 09:42:08 Tofe: seems v2.5 of OSE was pushed out. They included nyx module for hardware GPS :) May 12 09:49:55 Tofe: You seen PineLoader? Multi boot loader for Pinephone! May 12 12:23:57 Herrie: I tuned my system to within an inch of its life last year trying to get anywhere close to what yours can do :P May 12 12:24:55 I got it down to about an hour and five for a full clean build, but that wasn't definitely wasn't a stable configuration. May 12 12:25:18 (just "definitely wasn't") May 12 12:29:50 One good outcome was that I discovered that one of my case fans was fitted backwards :) May 12 12:35:20 elvispre: Yeah mine does in about 50 minutes May 12 12:35:48 But it's not very stable at the moment... Now testing last module... 7/8 did OK May 12 12:36:01 Now testing 1 that has issues posting, now posted, so I expect that one to be the issue May 12 12:36:18 Guess I know in about 30 minutes, then another RMA I suspect :( May 12 13:05:34 Yup seems that one is deffinately faulty :( May 12 13:05:49 Lots of errors on that single module, others pass without errors May 12 13:05:58 So I guess timing wasn't the issue, just this specific module May 12 13:53:11 OK now testing with 7 modules and created RMA again.... May 12 13:53:18 See what they propose May 12 15:48:22 Herrie|2: Making 128 GB of flawless RAM does sound like a challenge. One that you have paid handsomely for, I'm sure, but 128 billion bits all behaving in the same way. May 12 15:49:29 I expect you'll be more impressed when they actually do that :P May 12 15:49:45 elvispre: Yes indeed May 12 15:49:52 Well got 112GB flawless now it seems May 12 15:49:56 Doing some stress testing May 12 15:50:04 It's @ 2666 Mhz and not 2933 but well May 12 15:50:10 That's fast enough for 128GB I'd say May 12 15:50:22 I can tweak more but not worth if they're going to replace the whole kit again May 12 15:50:43 You need a matching set of course. May 12 16:04:21 Yeah matching set not easy May 12 16:04:34 When I RMA'd previous one they sent me back differnet type number... May 12 19:30:01 JaMa: Seems that with 7 modules instead of 8 my all cores finishes without issues, so I guess it's rock stable now. I'll see how results are vs previous and might play a bit with timings and memory speed still May 12 20:01:37 Herrie: not sure how IMC takes the channels when they are not used evenly, but in my testing 2 memory channels are almost double build time compared to 4 memory channels, hopefully it won't confuse IMC that much May 12 20:02:20 Well they say that when > 4 modules it uses quad May 12 20:02:24 So let's see May 12 20:02:40 Herrie: it might be interesting for you to replace it with 4x32G if they are willing to swap it during RMA (and if there is compatible kit with 32GB stick for your MB) which I doubt on both May 12 20:10:30 JaMa: I don't think X399 supports 32GB modules May 12 20:11:11 I only saw 16GB on the Asrock X399 Taichi QVL May 12 20:11:37 yeah, even on TRX40 they are quite rare in QVL May 12 20:12:53 Well not in QVL, but seems on Asrock forum they confirm it should work May 12 20:12:59 Though no details May 12 20:13:28 "MB does support 256GB, and confirm from our HQ." as per http://forum.asrock.com/forum_posts.asp?TID=12298&title=256gb-ram-on-x399-professional-gaming-motherboard May 12 20:15:59 it would be nice to bump from DDR4-1866 (DR) / DDR4-2133 (SR) to DDR4-2666/DDR4-2933, but for me the difference between DDR4-2666 and DDR4-3200 was minimal May 12 20:17:22 JaMa: Well seems timing makes quite a difference May 12 20:17:37 So if I can tweak that a bit it might help May 12 20:18:09 for me chromium-x11 build @2666 1745s, @3200 1674s May 12 20:18:42 and with 2 channels instead of 4 2717s May 12 20:19:10 and that was with tmpfs, without tmpfs 4008s May 12 20:19:56 Hmmmz mine is significantly slower May 12 20:20:01 but TRX40 is quite different platform, so X399 might be different May 12 20:20:09 7737.28 seconds chromium-x11-79.0.3945.117-r0/do_compile May 12 20:20:38 Seems this build was significantly slower in general May 12 20:20:52 117.01user 15.55system 2:58:27elapsed 1%CPU (0avgtext+0avgdata 36820maxresident)k 32056inputs+5456outputs (2386major+95086minor)pagefaults 0swaps May 12 20:21:04 Compared to my previous one with 128GB May 12 20:21:09 And this was with 112GB @ 2666 May 12 20:21:16 Need to check the CLs though May 12 20:21:21 in the results you sent me for test-oe-build-time you were around 3074s with 2 BB threads May 12 20:21:52 how many BB threads in this 2:58 build? May 12 20:24:16 This was with all May 12 20:24:22 So I guess a lot May 12 20:24:39 8 is still running, should have full set overnight May 12 20:24:51 yeah that would be 64 May 12 20:25:50 16 bb was fastest before May 12 20:29:34 Will see with the Ryzen DRAM calculator if I can push things a bit May 12 20:29:58 You already have a new system or still checking results? May 12 20:38:22 Tempted to order 8*32 sometime just to try if it works and how... If not happy send back May 12 21:29:42 Herrie: yes, I have 3970 system and happy with that, glad I didn't get 3990 May 12 21:30:17 Herrie: 8x32 is too much ram for 2990WX imho and you'll end with slower speeds again because of 2 dimms per channel May 12 21:31:03 that's one of the reasons why I've decided against 3990 in the end, because I would need 8x32 for that one, with 4x32G kit wendell is using it's actually slower than 3970 May 12 21:32:25 I would still like to benchmark 7702P, especially now after seeing how big difference 4 mem channels made, with 8 channels on Epyc it would be really something and it's less than 30% more expensive than 3990x **** ENDING LOGGING AT Wed May 13 02:59:58 2020
