Unstable memory does not lead to slow downs, it can achieve crashes, but then it achieves BSODs at similar rate. Image stays way it was till you press reset. When Ryzen does not have enough voltage, it does not slow down, if freezes whole system. Now, interesting part is that you are talking about slowdowns and game crashes. Therefore a lot of experimentation and BIOS resets. (Power efficiency lost.)Īlteration through power states is not something I would recommend as fine tuning each power state is PITA and may result in system which is unable to boot. There 2700X does easily 4.2GHz on all cores, but it comes at price of not having higher single core boost and loss of ability to decrease clock on idle.
OC means setting manual multiplier/fsb and voltage. That's best this chip can do without removing basic clock UP/DOWN functionality.
Once XFR2 is enabled, it turns to 4.3GHz max CPU with ability to go to 4GHz on all cores under full load as long as TDP or temperature limit is not breached.Įnabling PBO2 on top of that will increase achievable clock by some 25~50MHz in all situations.įor CPU OC, just undervolt CPU through Voltage offset and enable those 2 features. That's not really OC, that's out of the box behavior. I got easily my 4 sticks from 3.2 to 3.4GHz.Īs for your CPU OC at around 4GHz. Then calculate optimal values for stable situation.īut Agesa 1.0.0.6 which you have now made things much more stable. You should be running mem tests and count number of errors per time interval to find out optimal values in unstable situation. Well, for memory on Ryzen, your most important part is resistivity/impedance settings. I approached Gigabyte support to see if it was a problem with the mobo as there have been other issues with the recently like not being able to access the BIOS but that also seems to have gone away now.Īny one else seen anything like this and have an ideas? However, since having the earlier mentioned issue, i have returned everything to stock. I did also fiddle with the CPU OC for a while and was running at around 4ghz with no issues. Had a lot of issues with stability and couldn't get anything stable above stock of 2133mhz. So then i started trying to get more stability by using the AMD Ryzen Calc for Ram to ensure all the timings were correct. It would work fine for a week then fail to boot a number of times and revert to default (this is when i only had 2x8gb sticks).
First it was just failure to boot if i had XMP profile enabled. However, i have had some issues since building.
Last year i rebuilt my entire PC with the following specs: So round 1 might work ok but by the time the next game or round loads it is unplayable.
On less demanding games it seems to be less severe such as PUBG but newer games like battlefield it will sometimes crash the game. It will stay like that for 5-10 mins then reverts and everything is ok. I am having an issue where during gaming my PC will random just drop FPS down from say 100 FPS to 20-30 or in some cases 1 FPS.
