Losing my sanity over 3600 OC

Thought I'd help out in the country cup with a sub on my 3600 system for CineBench R15 single thread. It went downhill from there.

I knew my Ryzen 3600 system already had a Win7 install. When I dug it out, I noticed it had a single stick of 2133 ram in it. Need something nicer than that, even if CB isn't really ram sensitive. I pulled out 2x16GB of 3200 ram from another system. Enabled XMP in bios and... boot loop. Windows didn't like it at all, but I could go in the bios fine. Even turning off XMP I couldn't get Windows to load. The mobo never liked that kit, so I fished out 2x 3000C14 from another system. Much better.

Once into Win7, I knew I hadn't used it in forever so I updated the AMD chipset drivers, and GPU drivers. So far so good. I went to put on Ryzen Master, system rebooted during install. It didn't like that. Windows then would reboot during startup. It really didn't like that. I could still boot into safe mode, but what was causing the problem? It took a lot of trial and error, but there was an AMD device shown in Device Manager that had a driver installed but was listed as not working. I disabled it, and Windows booted again. To cut the story short, Ryzen Master couldn't be installed after this point so I have to do old school bios overclocking. At least I didn't brick my Win7 install. That would be the end of it as I'm not doing a new install!

I overclocked the ram to 3600C16 as I knew that was safe from previous use on Intel, and it seemed stable with a few minutes on Aida64 just to check it out. On the CPU I disabled SMT and reduced the cores to 1+1. Set 4.3 GHz at 1.4v and... got a run in. Hurrah! Banked a screenshot just in case, set it to 4.35 and... crash. A bump in voltage to 1.425 got a run in there and I called it a day. Going to 4.35 got me 205 points, compared to 204 at 4.3. Hardly worth the effort. With ideal scaling, I should get 206 but I'm not re-running in the hopes of getting one extra point. Also I assume I need a load more voltage to continue making way with clock, and I wasn't sure my air cooler was going to cut it.

In all, I think it took 2 hours, just to get 205 CineBench R15 points!

Then I saw, I never subbed on hwbot with the 3600 before, so I had to do a run with all cores. Wasn't happening at 4.3 1.40v. Insta-crash. Had to back off to 4.2 at that voltage to get a run done. For indication, I did do a stock run after, and it was boosting all cores to around 4.1, so hardly any OC improvement there. I wonder why I bother some times...
 
How was that board on other cpus? I never really liked. Asrock. Used them in the 754 days and they were total trash and I never used one since.

Seems odd. 1.42 I can pull my 3900x all cores to 4.7. right now I'm 4.5 1.36v.

What's your temps like? What bios?
 
Latest bios, with Agesa 1.0.0.4B. Temps, can't remember exactly but might be around 80C or so. I don't have the best cooler in there. 4.3 ball park seems typical for a 3600, bare in mind it is the lowest bin Zen 2 you can get in the West. What's your stability criteria? Here I'm only going for Cinebench R15 stable, which is a kinda mid-range load.

Welcome to AMD Ryzen overclocking. :(

Shocked you only saw 1 point gains for 100 mhz.. something isnt right there.

It's 50 MHz, 204 at 4.30 GHz, 205 at 4.35 GHz. If you scale the 4.30 GHz result then 4.35 should have resulted in 206.4 points. I decided it wasn't worth re-running for the chances of a single extra point or two (I don't know how rounding works, or if the 204 was an optimal run itself).

oops.

Doesnt change my sentiment, however.:)
