My 3800X arrived today, first quick bench

I was having a hell of a time finding any real benches on a 3800x, so I thought I would drop by and share this real quick. Might help someone make a choice. This is pretty much bone stock, PBO on, default ram speed 3200 and timings. I literally just fired it up about 20 minutes ago.

Sorry, Def not bone stock cooling. Custom loop, dual 360mm Radiators, Glacier C350AP block

Ooooh. So you're gonna be hitting 5000 points soon then.

Very easily, I would say. Samsung B die chips, I should hit 5000 just going to 3600 and better timings. I have a lot of voltage headroom on the CPU as well, at least it appears so.

One more quick bench, again no BIOS or memory tweaks at all yet. Just good cooling 78F ambient. The chip is doing 4.2Ghz on all cores by itself, not too bad. Just under 4.5Ghz on less cores.

I suggest doing a voltage offset to improve performance. I found optimal performance on my 3700x to be around -.05 to -.075 as stock voltage was really excessive.

Nice to see VR VOUT access on that board to show you the true CPU vcore at full load.

Can you test AIDA64 mem/cache bandwidth pls? thanks in ahead!

XMP speeds, 3200, tight but 100% stable timings

The good news is, almost hit 5000 just with tighter timings. The bad news is, apparently the latest BIOS 3.43 for this board is only AGESA 1.0.0.1 and it seems as though the memory speeds are locked to the XMP profile on this release (so I am reading) myself and pretty much anyone else can't go above XMP speeds or voltage or the system refused to post. Certainly seems like a lock of some kind, because I'm talking nano-hairs above.
I'm holding above 4.2 on all cores, no dips in a full Cinebench run, 4.525 peak on less cores. This is with minimum LLC and -.8xxx CPU offset, fixed 1.025 SOC, minimum LLC. Temps maxing out at 63c.

So think is pretty close to the best I can do until ASRock pulls head out of ass and gets an AGESA from this decade released. This beats my 2600X by 63%, same board, same memory (was benching at 3400 on 2600X, same timings), same cooling. That's not to shabby for 2/4 cores/threads more. I think 65% better can be expected once I can open up the memory OC.
