Great news guys, asrock released a new BIOS for my board with AGESA 126.96.36.199ABB, I'll report back with details
Hope it's better than the Gigabyte 188.8.131.52ABB they released for my board. In 3 hours of benchmarking...not a single core hit 4.4ghz. One core never went higher than 4.325!Great news guys, asrock released a new BIOS for my board with AGESA 184.108.40.206ABB, I'll report back with details
I'd like to sign up to the club! Seems like a happening place.
Not having much luck with PBO, seems pretty broken RN.
I believe that AMD say's that is half of the actual rate due to the I/O config on the CPU's.Hey guys ive just booted new system 3800x + Ch8 and my old b-die 3200cl14 ram iam getting horrible write speeds only 25000 and latency 75ns, any ideas on whats happening ?
Source https://www.tweaktown.com/reviews/9051/amd-ryzen-3900x-3700x-zen2-review/index3.html"In memory bandwidth, we see something odd, the write speed of AMD's 3700X, and that's because of the CDD to IOD connection, where the writes are 16B/cycle on the 3700X, but it's double that on the 3900X. AMD said this let them conserve power, which accounts for part of the lower TDP AMD aimed for. AMD says applications rarely do pure writes, but it did hurt the 3700X's performance in one of our benchmarks on the next page. Memory latency is a bit high at stock, but you can overclock the memory quite easily".
“This is an expected result. Client workloads do very little pure writing, so the CCD/IOD link is 32B/cycle while reading and 16B/cycle for writing. This allowed us to save power and area inside the package to spend on other, more beneficial areas for tangible performance benefits”.
Some of the bios releases also won't let the cpu boost to the advertised speeds....keep that in mind also. (Especially some from Gigabyte)Here's my submission. Running a 3700X stock at the moment, with Gigabyte B450 Auros Elite with F42A BIOS and Corsair LPX 16GB 3200MHz @ C16. Everything works fine, haven't had any issues except for the core clock that doesn't quite boost to the right frequency, but that might be due to using the stock cooler in a fairly hot environment (ambient temps are pretty high, can't do a lot about it). I'll post an update once my Noctua socket adapters arrive.
Exelent thanks for the info , gess my ram speed is alright thenI believe that AMD say's that is half of the actual rate due to the I/O config on the CPU's.
I need a CPU-Z ValidationSign me up! I just installed my 3900X yesterday. I've got it in my Asus B450-I ITX Mobo that I had a 2700X in prior.
I've run into the FCLK != MCLK cold boot bug on their 2501 BIOS. I was able to boot my memory changes by lowering the FCLK one step. And, I was able to sync them in Ryzen Master. I'm presently running 3600 MT/s using 1800 MCLK / FCLK. Aida scores 56,608 MB/S Read, 55482 MB/s Write, 57,001 MB/s Copy, 66ns Latency. So far the best I've done. That cold boot bug sucks; hopefully Asus updates the bios to fix otherwise I have my eyes on Gigabyte Master X570 and a new case.
It is waste of time for the vast majority of 3000 series owners to put much effort above 3600mhz. In more than 9 out of 10 cases your infinity fabrick will prove unstable above 1800mhz. Buildzoid ahd a youtube video about his fabric going up to 1900mhz with 3800mhz memory speed and achieving some mild success. BUT he clearly admits that that will only happen for 1 out of 100 chips. It is a pursuit for fool's gold. Unless there is a bios release that has a major impact on fabric overclocking it will be fruitless for most of us.Thanks for the ad!
Congrats on the score os2wiz! How have you found the memory scaling up there over 3600mhz?
(also before anyone pings me- the verification shot shows me pussing out at 1.42v on water for a limited bench run- she wont live there lol)
