Discussion on Asus X-Hero Z-370 Wi-Fi 9900 kbps performance (initial test)
Asus Z-370 X-Hero Wifi + 9900 ks 5 ghz @ 1.28v, 4.7 ghz cache, 4000 mhz DDR4 CL-17. Who claims the Z-370 Asus X Hero isn’t sufficient (first test) will adjust voltage and increase MHz later (7 hours real bench), without throttling. I’ll tweak the first test to try 1.24v next. Real bench requires about 0.020 - 0.030v less than Prime 95 26.6 non-AVX small FFTs. So far it’s performing well for Z-370 X Hero? Update: At 1.28v it passed Prime 95 small FFTs on AVX, at 1.25v it passed on non-AVX and ASUS real bench. 5 ghz all cores, 4.7 ghz cache. @ 1.25v manual core voltage, load line level 6, no AVX set, 4.7 ghz cache, 16GB DDR4 4000MHz CL-17 tuned.
Thanks for the update. I'm checking 1.26 v 5 ghz with all cores and 4.7 cache. After an hour, I've completed 95 small FFTs without any errors so far.
Does employing the AVX instruction set in Prime95 cause any failure or downclocking? Consider alternatives such as RealBench. Start with a 15-minute stress test—it delivers a more accurate high-end workload and actually uses AVX. Although I prefer Prime95 with AVX, the stress it applies to a CPU differs significantly from real-world conditions.
Hey there
I ran prime 95 "small ffts"
@ 5 ghz all core
@1.25 v bios
4.7 ghz cache
Load line level 6 (7 is max 6 no drop)
Woke up after 8 hrs with no errors or issues and no throttling in hardware monitor 64
I’m feeling pretty good right now and temperatures stayed around 81°C max
I saved the pictures of all the stress tests and temperatures for proof
Trying 1.24v. Ow
I passed 8 hrs of asus real bench 2.56 stress test yesterday @1.26v and ram at 4000 MHz cl-17
No issues so far with 1.24v tests
Good day everyone, here’s my latest update on the ASUS X Hero Z-370 with a 9900 K speed. I completed an 8-hour ASUS real bench test at 5 GHz all-core and 4.7 GHz cache. The results were solid. I used 1.25 V manual Vcore, load line level 6, and 0 AVX ofset. During the test, I achieved prime 95 small FFTs without any AVX issues, even while sleeping for 8 hours. No throttling was observed, and the voltages stayed stable.
I also tested prime 95 small FFTs at 1.24 V, which triggered a WHEA error but no issues afterward. If I upgraded to a Z-390 apex, would the voltage drop to around 1.21–1.23 V? Should I keep the 9900 K at 1.25 V for these 5 GHz tests on the Z-370?
My current CPU is an 8700 K with Rockit coolers and copper IHS. It needs prime 95 small FFTs non-AVX at -5 GHz all-core, -0 AVX offset, -4.7 GZH cache, -1.27 V, load line 6, and 4000 MHz RAM. It requires -5.1 GHz all-core, -0 AVX offset, -4.8 GZH cache, and -1.34 V manual Vcore.
For the 8700 K, I need it to run at -5 GHz non-AVX with no AVX offset, -4.7 GZH cache, and load line 6. Should I keep the 9900 K at 5 GHz at 1.25 V, or should I stick with the 8700 K? My 8700 K has liquid metal and excellent aftermarket copper IHS. It’s a solid build, but I’m considering selling it for $450 plus CAD.
