It might help to take a screen shot and attach the image here making sure it is readable. There may be some other setting that messes up at 2 MHz. (I am thinking in terms of setting bandwidth to 2 MHz with the front end set to 500 kHz, for example. Simon seems to have that handled but you might have found a small hole.)
You mentioned the Ryzen 7. That is new enough there might be an issue with special instruction sets. I am not sure if Simon uses them, though. Linus Sebastian mentioned in passing that some configurations with AMD CPUs may be a little sketchy. (That said, he also mentions his home machine is all AMD at the moment.) Are you overclocking by any chance? And how is your memory cooled? I am idly thinking of a setup a little like you describe. It's enough I could still run my video software on it.

Hi thanks for the input its much appreciated
1st we'll get the computer talk out of the way
![Mr. Green :mrgreen:](./images/smilies/icon_mrgreen.gif)
, i have been AMD most of my computer life with a few Intel's chucked in over the years and this is my biased account , even the Laptop is AMD .
You will not be disappointed if you go Ryzen + a good motherboard and GPU but choose whatever you like , this all AMD thing absolutely smokes , its the 1st computer i have had (but not my 1st built-up one) that i can play a very graphics intensive game turned up to full where the GPU does most of the work and the CPU just loafs along at 40-50% and that's with say the web browser and other stuff open on the external monitor at the same time .
No need to overclock btw , Ryzen Master software also balances out all the cores so they do share properly , the memory has heatsinks on them , at 1st i used all the software to check everything like temps/process's/usage and the likes all open on the other screen and several types and once i got the feel of what was going on and very satisfied after a month or so i hardly even open them up now .
Back to SDR , well today i did look around in the software to see what i could find related to 2Mhz only issues and did come up with the setting for "Buffering" was turned on to X2 and not the default so i set it back to default (i must have set that on the 1st day for some reason? and forgot about it) , so that's all i could find at the moment , ATM I'm using 3Mhz BW and the memory size is 1.2Gb with CPU waving between .4 and 1.2% .
I can't do a screenshot when it happens as it's an immediate close as i mentioned , just that noise then all gone and restart , but so far so good and no great drama , if only there was a "Make Coffee" button in the software , cheers
