Anyone oc Radeon 7?

[liam.waterfield96]

Managed to get 1900mhz but when I go to 1950mhz it crashes must be going wrong somewhere. The card should oc tpast 1950mhz I know cards are different. I must be doing something wrong.

[liam.waterfield96]

Even when I auto overclock gpu via radeon wattman supersition benchmark crashes?

As you said you know, not all cards OC the same. You just got a bad lottery roll.

[liam.waterfield96]

Even with that minimal overclocking that pushing it. radeon 7 can oc like 2100mhz can't be that much of a difference surely

Sometimes you pull bottom of the barrel trash. It happens.

I dont know anything about the overclocking numbers on R7, but of I was you, I go back and read to see what the average overclock is.

I get the same behaviour with my Radeon VII but I don't bother overclocking GPU's much these days, I don't see the point. 4K and 1440p gaming is easy for the card at stock clocks.

Edit: I had to double check, 2000MHz is good but will crash at 2025MHz. Mines on water.

Been doing a bit of testing and I found if I unlock voltage control (MSI Afterburner) without increasing Vcore my system would lock up at 1950MHz. Now at 2050MHz @1125mv a quick run in Unigine Valley doesn't lock up, about to see if my score improves in Firestrike.

2050MHz @1125mv was unstable in Firestrike's combined test so bumped vcore to 1135mv to run stable but core clock very seldom went above 2GHz and I'm hitting the 300w power limit (wonders if I should have a look at the powerplay table mod).

Now at 2GHz @1135 mv as above 2GHZ was unstable for gaming. Will see if I can lower vcore for gaming workloads.

Edit: ended up at 1130mv
Edit 2: after 2hrs gaming it decided to lock up on me again so bumping vcore back to 1135mv.
Edit 3: a couple of more lock-ups vcore ended up at 1150mv (not sure of long-term) but still not stable. Going back to stock settings now, had enough of messing with this.
Edit 4: couldn't leave it at that so now at 1950MHz @1120mv, will do more testing tomorrow.

I've got a feeling it might be my PSU that's making it crash but could be temps aswell reaching limit and crashing just going to undervolt it at the moment think i got it to 1000mv ran 3D mark and got through it but i did go to 1050mv just in case going to try again. for now i going to UV and might oc the memory see if I can get a sweet spot for the time being.

[liam.waterfield96]

Reason why I thinks it crashes because it's hitting a power limit I using 650w psu from my old system it runs default but 650w able to run 300w+ GPU when oc plus my be quiet dark rock 4 cpu cooler is around 250w / x570 motherboard with 3600x ryzen cpu & 4 be quiet wings 3 fans and two lots of 8gb RAM not sure about the watt usage but got a feeling I am using too much power for what I want but need to look into it further.

I'm very new to OC so forgive me of any ignorance.

[Spec_Ops_Ape]

Temps shouldn't cause it to crash, the card will throttle hard if it gets to hot (junction temp of 110°C and above).
BeQuiet's PSU calculator puts your usage at under 500w so 650w is plenty unless you have some cheap, no-name brand then possibly a PSU issue.
Are you overclocking your CPU/RAM? If yes, are those stable?

[liam.waterfield96]

Corsair PSU 650w and 3600x already oc so didn't touch it & RAM 3200mhz

Should be all good on that front so probably just the card not liking being overclocked much.

i don't have a radeon vii, but this is how i overclock in firestrike with wattman.

1. start with memory and power limit at default settings. fans at 80 percent.
2. set voltage to 1000.
3. run firestrike demo till conclusion of fight scene.
4. if i see any artifacts, stop demo immediately and increase voltage by 20 mV.
5. if there are no artifacts and boost clock is maintained, increase frequency by 10.
6. if there are no artifacts, but boost clock is not maintained, increase power limit by 10 percent.
7. increase values incrementally until a maximum is found. then drop 30 from the frequency to keep things stable.
8. increase memory frequency by 50 until it becomes unstable. if unstable, drop back down to the previous 50 and test again with hwinfo64 running in background.
9. if you are getting gpu errors in hwinfo64, drop down another 50. if no errors, that is where i would keep the memory overclock.
10. drop fan speed down to what you consider an acceptable noise level and monitor temperatures. lower frequency and voltage to hit desired temperature target.

What would you recommend me to do now?
seemed to have found a stable uv of 1025mv (stressed tested on 3d mark got 99.7% best score I have got) and have just ran hitman 2 benchmark passed got 47.8 avg fps (4k)

1. I am wanting to reduce fan speed to maximum of 50% (have done this before and passed and noise level was fine)
2. Would like to add a OC to it never gone past 1950mhz but have gotten it to 1900mhz before and passed.
3. Can I max out the power limit I think you can it just gives you that bit of margin incase it needs more voltage.
4. Finally Memory frequency can it get to 1200mhz or to find a middle ground.
