Title: Don't recommend Ryzen
Post by: lupaz on 2017-07-05, 17:01:54
Hi all,

Just a short message.
I bought ryzen 7 1800x with mobo asrock taichi.
If you think you can overclock it at their advertised boost clock speeds of 4mhz, think again.

At 3.8mhz it's still unstable in my case. It could be memory, but I never had problems with intel...

well, for those who never overclocked before, you should know that the path to overclocking ryzen to something worth of spending a lot of time doing it isn't that easy. Especially in summer.

:)) I have intel I7-5820K unlocked with water cooler and etc. for overclock,, but still after Overclock much more 4.00 ghz  to 4.3 /via BIOS auto options CPU Upgrade for overclocking/
this begin to be unstable, especially in long time render, make crash and restarting's////Besides with complete absence of overheating, 70-75 C :)))
So don't recommend Intel:)))

What motherboard are you using? Thanks.

If it runs at just 3.8mhz then you should be indeed concerned and RMA your chip asap ;) And you could replace it with some 386 to get almost 9x better performance :)

Too bad you have a bad OC experience. Friend of mine has a 1700 and runs it at 4ghz just fine on a crosshair hero IV, since he got it on launch. To be fair, he has an AiO, but still...
Recommendations based on just a single user experience don't make much sense.

For info on OC and voltages see the Ryzen Owners club thread on overclock.net (http://www.overclock.net/t/1624139/official-ryzen-7-1800x-1700x-1700-owners-club-4ghz-club), it has a table for achived OCs with voltages. It usually averages out at 4ghz (shown as 3999mhz)
For Corona performance see the ryzen Corona benchmark tables (https://corona-renderer.com/benchmark/?cpu-type=ryzen&submit=Search).

These are good indicators of whether you should buy ryzen or not in terms of overclocking.
