    1st real flight was in a Ford Trimotor in the early '60's. A $5 ride that my uncle paid for. I was hooked.

  1. I'm going to have to run that test again. I found one of my hwinfo logs from that time (22 Nov) and it shows the AVX speed (4.7GHz) 67% of the time. Core 0 was AVX 48% of the time. The other 7 cores ranged from 65-74%. All 8 cores were at 4.7 24% of the time. On average 6 of the 8 cores would be at 4.7 and 2 cores would be 5.0 at any given time.
  2. If memory serves (which is always iffy) when I used AVX offset in my standard test flight around the patch at KLAX I would see the frequency drop intermittently. Most of the time it was full speed. So I don't use AVX offset for normal flying because I would only see brief spikes in my temps.
  3. I'm not concerned at this point. After running the RealBench stress test for 15 minutes at 5.0 with HT off, and a max power draw of 167W, the max VRM temp reported on my board was 51C. I have no direct cooling of the VRMs; just the 3 side-mounted 120mm fans.
  4. It might depend on the silicon lottery for your specific 9900k. I can run at 5.0 with reasonable temps on all cores with HT off. I even had it running at 5.2 for a couple of days but had one BSOD so I backed it off. With HT on I can reasonably run at 4.8 without the temps getting out of hand.
  5. I've been trying them out this morning with my standard test flight around KLAX using TrackIR. Take off from 25L, make a 20nm downwind over Long Beach and land 25R. When I turn onto the crosswind over the Pacific and look left to the city all the autgen buildings are black and the textures pop after a couple of seconds. But the FSDT KLAX is still fully visible, which is an improvement from before. My VRAM usage is just under 9GB vs. 5GB before. RAM is 10GB vs 8.5GB. [GRAPHICS] MAX_TEXTURE_REQUEST_DISTANCE=320000.000000 ENABLE_MEMORY_OPTIMIZATION=0 [TERRAIN] TEXTURE_SIZE_EXP=10 UseGlobalTerrainView=True My autogen settings were not maxed out for this test which was a leftover from previously having Orbx SoCal loaded, which is a frame killer and stutter inducer. I'm going to re-run the test with only OpenLC NA and max autogen. As soon as I look left: After a couple of seconds: Video showing autogen texture popping:
  6. It's a different story with HT. My 9900k runs about 10C hotter with HT on than with it off. RealBench wll fail or BSOD at 5.0 with HT with some thermal throttling on 1 or 2 cores plus the CPU package. However, it easily runs at 5.0 with HT off in the 70's with peaks from 79-84.
  7. Created the return on Amazon. It's packed and ready for UPS to pick up tomorrow. I ran comparisons between the Ryujin and the EVGA in Cinebench (which takes 20 seconds to run) and RealBench (15 minutes) . The Ryujin did better than the EVGA with HT off, but the EVGA did as well as, or better than, the Ryujin with HT on. The values are the average peak temps for the 8 cores. Cinebench R15 HT Off @ 5.0 HT On @ 5.0 Ryujin EVGA Diff Ryujin EVGA Diff 66 °C 73 °C 7 °C 91 °C 81 °C -10 °C RealBench 2.43 (15 min - 4GB) HT Off @ 5.0 HT On @ 5.0 HT On @ 4.9 Ryujin EVGA Diff Ryujin EVGA Diff Ryujin EVGA Diff 76 °C 88 °C 12 °C 94 °C 94 °C 0 °C 93 °C 94 °C 1 °C HT on @ 5.0 resulted in a BSOD for both coolers about half way through.
  8. Ya. It appears that they put all of their effort into the bells and whistles of the OLED display and the actual functionality was a poorly implemented afterthought.
  9. Big disappointment with the Asus Ryujin 360 AIO. I don't see that it cools any better than the EVGA CLC 280 and, even worse, it doesn't even have the basic features of the EVGA cooler, like showing the coolant temp and allowing setting the radiator fans based on it. And as for instructions on how to use the software: "Please visit the product support page at to download and install the control software." The download page for the Ryujin has AI Suite III, LiveDash, and firmware updates, but no additional documentation. The LiveDash is easy enough to use. It lets you select the following: Parameters you want to display on the OLED (although it doesn't remember previous choices - everything is unchecked when you open it) What image or animation to display, either predefined or custom A custom string to display with the ROG logo during boot Lighting control for the LED stripe, if you don't have an Asus mobo with Aura The first choice is the only one I used. Pump and fan control is done from AI Suite, which seems like it could be an issue if you bought this to use in a non-Asus mobo. Unfortunately for me AI Suite didn't see the radiator or VRM fans leaving me not knowing how I was supposed to control them, as there is no documentation or FAQ. I found out from a new review of the Ryujin AIOs by Tiny Tom Logan on OC3D's youtube channel. I found that my system doesn't see the USB connection on every boot, especially cold boot. Tom pointed out a non-trivial issue. Namely that the pump and fans all operate based on the CPU temp, but not the actual temp reported by the CPU; rather, it's from a mobo probe that has a definite lag and under reports the CPU temp by 5-10C. Although I found that it also spikes intermittently by 10-15C, which caused all the fans to suddenly run high for a couple of seconds before slowing down again. I adjusted the fan curves to eliminate those annoying run-ups. The best thing about the Ryujin 360 is the set of Noctua fans. I've never used them before and I really like them. The little VRM fan on the block is definitely the loudest thing in my system when it spools up. I don't know the speeds of any of the Ryujin fans because they don't appear in the fan list that shows the current speeds. The fans only show up in the profile graph that lets you customize the speed by percentage. I'll run some direct comparison tests in the morning with the Ryujin and the EVGA CLC with both HT on and off to get some hard numbers, but I'm leaning toward returning the Ryujin to Amazon. I think I can put the $279.99 ($301.06 w/tax) to better use. Maybe it's time I started looking at a custom loop.
  10. Going from a 6-year old 3570k to the 9900k has been a definite improvement for me. Although I've gone down a rabbit hole the past few days trying to determine if there's a setting that would avoid the stutters when flying over Terminal Island in Long Beach with Orbx SoCal. I ended up turning of all autogen, reflections, and shadows to no avail. There's something about that scenery at that location that hammers the CPU. With HT off, 6 or 7 cores would hit 100%. With HT on, 14 threads would hit 100%. Although I can't run with HT on at 5.0 when AVX kicks in because of temperature spikes. New AIO supposed to be delivered tomorrow...speak of the devil, the USPS just delivered it to my door. Welp, time to open up the case again.
  11. Yes, mine was throttling back to as low as 4.1 before I set several parameters to max values: Long Duration Package Power Limit = 4095 Package Power Time Window = 127 Short Duration Package Power Limit = 4095 CPU Core/Cache Current Limit = 255.75 CPU Current Capacity = 170% DRAM Current Capacity = 130% VRM Spread Spectrum = Disabled
  12. It's an adventure of exploration. I'm having a lot of fun with it.
  13. The back has a small grill that's about 7x14cm. It has the slightest outflow, even under load when the radiator fans are high. The bottom of the case can take 3 x 120mm fans, so that's a large open grill at the moment. There's definitely air coming out of the bottom under a load when the intake fans are at high speed, ~1500 rpm. I can add 3 more fans to the bottom if I need them for better GPU cooling, but I'll have to add a Corsair Commander to power and control all 6 fans and to provide an extra USB header for the LED controller of the additional fans.
  14. Manually setting AVX offset to 3 made all the difference. That ran the cores at 4.7. I let the test run for 30 minutes with small FFTs and the max core temps ranged from 77 to 84 with CPU Package 84. The Prime95 version is 29.4 build 8. I'll see what my temps do when I get the Ryujin 360 next week. Big thanks for that advice!!
  15. Good question. I captured stats for most of my KLAX circuits. Here are a couple of examples. Orbx Global Only Core #0 Core #1 Core #2 Core #3 Core #4 Core #5 Core #6 Core #7 Min 42 41 40 41 37 38 39 37 Avg 65 53 62 61 61 60 59 57 Max 76 73 84 82 86 82 83 81 Orbx OpenLC & SoCal Core #0 Core #1 Core #2 Core #3 Core #4 Core #5 Core #6 Core #7 Min 34 36 35 34 35 33 36 34 Avg 61 50 57 55 55 54 54 52 Max 70 69 78 77 79 76 76 77 I'll update it after I install the Ryujin 360 AIO.
