Need 8350 OC views! Odd OC
I have a pretty cool 8350 running stable at 4.6 ghz with 1.275V, but pushing it up to 4.8 causes it to freeze. I've tested everything from 1.465V to 1.48V without success. I'm using a 990fx sabertooth, CM 850V PSU and an NH D15. I thought I could get it up to at least 4.8, but it's still not working. Any advice?
Yahoo! Glad to see you got somewhere close to what you wanted.
I found when OC'ing my 8350 that the percentage gain above 1.4v / reasonable temps for a 24/7 OC were negligable. 4.4 -4.6 was pretty doable at 1.35/1.375 v, which yielded low to mid 50C operating temps while gaming, on a not spectacular cooler. Which imo are happy temps for a FX series cpu. And that is with a R290x contributing it's many watts to case heat lol.
Unless you just want that screenshot of CPU-Z or w/e to make ya happy, and then drop it back to 4.8/1.4 for real world use, since your gaming/computing experience will have no noticeable difference.
But the heat and shortened life at 5Ghz are definitely a thing.
Silicon lottery might have replied "DENIED". I'd suggest looking in the AMD OC forum here on tom's, as there could be minor adjustments to achieve your goal. I believe 4.8 would be quite feasible, but since you didn't mention temperatures rising at that attempt level, I lean toward bad luck in the lottery. It does happen. A 4.6 at 1.275 seems solid, so perhaps another tweak nearby could help reach higher numbers. To be sure, checking it out might be useful.
Exroofer shared some insights about the lottery results and possible adjustments. He suggests checking specific tweaks in the AMD OC forum on Tom's, noting that a 4.8 setting might be feasible but could be due to luck. He mentions a 4.6 at 1.275 was solid and hints another setting might allow higher numbers. He recalls an experience with his recently replaced 8350 where increased RAM speed improved stability, though it took some time to confirm.
The problem was AMD overdrive, though I didn't intend it to be the cause. It's been 4.8 at 1.4v stable so far.

Exroofer shared his findings on optimizing performance under certain conditions, noting that gains above specific thresholds were minimal. He mentioned achieving acceptable temperatures around 4.4-4.6 with lower voltages and moderate cooling solutions. He emphasized that these temps are suitable for an FX series CPU, especially considering the additional heat from a R290x unit. He also warned about potential issues at higher frequencies and shorter lifespan, suggesting a possible need for a Ryzen 5 1600 upgrade soon.
Not really. Prime95 will reach much higher temperatures than any regular use ever will.
For gaming, I think you're probably in your mid-50s. If you're at 1.4.
Ambient definitely has an impact though.
Also, I noticed I could reach 2400 Northbridge on my rig.
4.6 /2400 NB benches and runs significantly faster than 4.8/2000 NB.
This provides a 15% boost over the stock turbo, plus a 20% boost over stock.
If I recall correctly, this resulted in a 35% higher CPU benchmark (depending on the test) compared to stock. It's been a while.
A 35% gain is definitely impressive.
*Note. NB bumps will also influence RAM speeds, I'm pretty sure I'm remembering it right.
So you'll need to adjust the RAM speed manually when doing this.
Also, NB bumps don't require higher voltages. They're more about thermal management.*
