What's the normal ambient temperature of the room your machine is in? How much does it fluctuate? Your performance makes me think it's closer to 20*C -- is that correct?

tcclaviger Please, if you have points of contention let me know, I believe in life long learning and have no issues admitting I'm wrong or learning from other enthusiasts.

Thanks for the effort, I will read through it, interesting stuff indeed!

nick name Something I toyed with today was reducing IF bandwidth to see if I could increase IF speed above 1900MHz. I could not.

tcclaviger 3800/1900 is far more common on single CCD chips when you just throw it in an set the dividers. On dual CCD chips, it often requires playing with settings to get it fully stable, but some of them Dual CCDs are fine at 1900. This is why Silicon Lottery was selling 1900 stable 3900/3950s for a premium even though they weren't the best binned for core speed/voltage scaling.

It does seem to be getting more frequent, or, people are claiming stability when it is semi-stable. 1900 is finicky like that on dual CCD chips, it'll appear stable, everything will work, and 12+ hours later, you'll throw a bus error, which is sometimes caught by WHEA and corrected and sometimes not, causing a BSOD or data corruption, leading to a slow crash where everything just slows down over 30 second to 1 minute period until it completely hangs but doesn't BSOD. Simply running a series of stress tests and benchmarks that pass will not validate it. It requires time, use, and is a pain in the rear to validate.

The settings I used are a composite of little tidbits I found from various sources all thrown into one configuration. Credit for various things will be provided and sourcing for people to go read deeper if they want to. I am attempting to make this as easily digestible as possible (and failing so far).

The analysis is taking longer to prepare than I expected, as I have no established work flow for this since I never do presented data analysis at home and don't have any of my templates to use that I have at work (and they cannot come off the air-gap network there). At home I chuck it all in an excel table and do the analysis in my head since I'm not showing anyone else usually.

Whats so special about it? (I am asking as complete noob regarding ram oc, so my post may be dumb and funny, sorry guys lol)
I think he meant with a raised BCLK, or maybe not, don't know. Both my Ryzen 3000s does 1900 FCLK 3800 Mem, but I've heard most are unstable above 1867MHz.
