3800X on X370 Crosshair 6 Hero

[tufpistol]

I did some light reading on installing 3rd gen CPU's in this motherboard finding hosts of people having issues. I loaded motherboard settings to defaults and BIOS 7201 and restarted. I went into BIOS again and set voltage to 1.35 and DRAM Voltage to 1.4 and restarted. Next I installed my 3800x. My computer booted right up!  After running some initial performance tests I saw comparable numbers to other users with 3700x or 3800x. Awesome!

So I go out to get the latest available BIOS 7403. I continue messing with settings and find that an all-core 4.4GHz clock speed is giving better synthetic results (Cinebench R20) than standard auto-clocking. I leave this alone as the performance is way better than my 2600X. So now I begin dialing in the RAM. I set the speed of my G.SKILL 3200 CAS 14 kit to 3600MHz at 1.45V. Success. I continue on to 3666 and it benches without issues. Now I have booted to 3733 and ran AIDA64 benches with success. What amazing leaps Ryzen has made. While this chip isn't overclocking in the classic sense... I am still having fun dialing in these results. If this is stable, I will attempt CCX clocking next.

Well first off you have to Flash the BIOS.  Also you do lose PCIe lanes and some other tech.  I would go x570 or get a X470 and flash it and use your 3xxx CPU and what not.

Very nice!! I have the same setup, except a 3700x instead of 3800x and just have mine at 1.35v at 4.2ghz all core and sounds like the same RAM kit, Flare X 3200mhz left at XMP settings. Havent tried pushing RAM at all.

Lose PCIe lanes? First I've heard of this. You do lose bandwidth as compared with PCIe 4.0.

Even the 2080 ti will not saturate PCIe 3.0x16 anyway.  The only gain I see from PCIe 4.0 is the m.2 drives (which I don't need). X470 is what I would buy if I was in the market for a new budget board. Otherwise X570 for newest tech.

I am not sure what gains I could see from 3200MHz CAS 14 in gaming, but the synthetic benchmarks look promising! More bandwidth AND a reduced latency.

This is faulty Turtle... you dont lose PCIe lanes. Those are hard on the CPU, not the motherboard. If you read the post fully, you will see he is on the very latest BIOS, 7403 on the board with the 3800x....

It can help because the Fclock going 1:1 at 1600mhz where its best at will produce some gains, not a ton. LTT recently did a video demonstrating a lot of variables and differences in the RAM clocks in terms of FPS performance in games.

 Precisely! I have the Fclock set to 1866 also! Currently stable in R15, R20 is throwing some errors.

Its generally advised to never go above 1600 on the fclock as anthony explains in the video.

Pick up an X570 asus prime and sell the crosshair 6?

You quoted the whole original post, but you didn't read it? OP already has the motherboard and reports that it works great, why would they get X570?

Sounded like he was having issues or something

Only the first line says anything about problems, and that was that other people reported issues. Every other result looked peachy

Read the OP? Is this some strange new rule?

 

@tufpistol Per CCX OC is a great thing. I let the other CCXs do what they want and set CCX0 to 4.5 on my 3900X. Tis nice.

What voltage do you use for this? I will give it a shot here soon. I initially attempted 4.5GHz all core with 1.39V and failed but didn't want to cross 1.4V. Idle temps are around 35C and AIDA64 load test after 5 minutes is 75C

Around 1.4. Binning is a huge factor though with Zen 2.

I have noticed this through the Ryzen generations. Cant wait to play on AGESA ABBA release from ASUS. This chip autos to nearly 4.6 from my initial testing but as previously stated, the all core method seems to be the way to go.
