[Official] AMD R9 390/390X Owners Club - Page 1001

post #10001 of 11908
I've been experimenting with overclocking my 390x a bit and wonder if these results seem normal. I'm not going to be increasing the voltage because it looks like it would be pretty hazardous with my 600w PSU.

Anyway I seem to have no problems at 1080Mhz. Beyond that a got a little artifacting at 1085. From what I have read 1080 is a little weak at +0 V but not too far off.

What seems odd to me is that memory clock. I have tried as little as 10 Mhz increments either way (underclocking as well as overclocking) and nothing seems to improve my Uningine Heaven score. This is both at my stock 1060 clock at at my overclocked 1080 and I think at 1070 as well.

Is it normally to get no gain at all from a VRAM overclock? I haven't tried smaller increments than 10 although if I did the benefit would be so small it would just be to satisfy my curiosity.

RAM OC gains little due to RAM bus width.

You need larger increase to gain something discernible in bench and also depends on bench.

You also need to be setting RAM frequency closer to the end of a RAM strap to gain the most performance for the timings of that strap.

390/X also have slightly tighter RAM timings "out of the box" so gain is less vs tightening RAM timings on 290/X.

Also the 390/X has tweaked memory controller timings vs 290/X from what The Stilt has posted. When we add VRAM_Info from 390/X to 290/X (with mos to make it compatible) there is again a ever so slight boost.

All in all the 390/X out of the box is tweaked more vs 290/X.

CPU- 3770k @ 4.7
GPU- Strix 390x @ 1150core 1600mem
Windows 10

Going to try and OC it more tonight and see. It's so humid in the south and its been hot. rolleyes.gif

Love seeing TimeSpy scores, keep up the good work fella's.

I'd always discounted claims that memory and core overclocking had any relation to each other, but today I more or less proved it while playing around with my bios to lower the voltage for all 8 of my pstates.

For example, if I run 936 on the core (pstate 5, aka the 3rd highest) with 1740 memory (my max) at a minimal core voltage, I will get massive memory artifacting. Memory artifacting is very different from core artifacting - more like flickering, in this case, while core artifacting is white snow. Running OCCT with its error checking on I get 0 errors, but the screen flickers unusably.

Now if I lower memory from 1740 to 1500, it's immediately solved. But if I raise core voltage enough (like 50 mV), it's also solved. And this is a straight up on-off thing: at one voltage setting it's flickering to hell, and then with 6.25 mV more it's completely gone and stable. AUX voltage seems to have no effect.

Raised memory by fifty, then raised it again. I've never had gpu memory clock this easy before. Might try for more later. http://www.3dmark.com/fs/9398840

Guess I better add the scores from the shiney new benchmark.

Here is clock stability test I made on Sapphire 390 Nitro in Witcher 3 with and without Power Efficiency option enabled:



I did this test because game was stuttery as fcuk.

Is AMD completely insane? Power Efficiency mode completely breaks performance and smoothness and is enabled by default. How many users and reviewers even know about that? How many users are even using this Radeon Settings panel? How could they set something like this by default?

Is there any difference in frame rate?

Well if there is a lot stuttering with Power Efficiency option enabled then surely there is differece, much more FPS drops and less consistency.
post #10009 of 11908
Normally if I got stuttering in a game I'd assume it was from lack of CPU power or something running in the background. If upping the GPU clock fixes it, then it could be tied to GPU.

Its all over the net already, at least in the US for english speakers. It was discovered when people were getting poor firestrike scores. Mines been off since day 1 anyways so ive had no issues. Haven't even bothered trying it with it on haha.
