The msi 390/x overclocks the best because it has 2 extra vrms. Right?

1. YES, and a little Nope.
2. Nope.
3. Nope as well.

Higher ASIC Quality does mean a lower stock VID. 70% has an equivalent VID. Not that of the second statement.


Higher ASIC might mean you can clock fairly good at lower Voltages but to how much is another matter.


MSI may have a better board. But they don't have the control to the chip's OC abilities. Unless you buy a guaranteed one. Like a LIGHTNING for example. But even then, what you can achieve is still a lottery

mine is lower than that and my card OC's rather well.

ASIC quality doesn't seem to matter as much on the Hawaii archtecture as it does on Maxwell. Keppler and Fermi before it, was pretty random too.

Totally random thought: I have got to find a custom bios that'll help performance on this card....

So close to 1700, so close. Pushing to 1250mhz core made it artifact a bit, I didn't want it to crash so settled on 1245. Before VRM1 got into the 70's C it was fine, but once over 70C I start to see some flashes. Signs she's about to go black. Gotta get it cooler. I've been working on figuring out what to do, aside from putting the PC out in the cold (which I may do) I'm not sure how to get the VRM's colder. Seems its just the voltage making them so hot. If I run at 1000mhz and -75mv (which is stable) then my VRM's barely go over 40C. Overall, very happy with this card though.

Whelp guys I just learned an important lesson. Apparently my cases air flow sucked complete a$$. I added 3 fans since the last time i posted. (replaced my old ones) and my god the temps have been much more reasonable. I had a 10-12 degree drop in gpu temps. Before I was hitting 86 87 degrees @ 1130mhz with 69 volts. After that I added 2 fans and it dropped down to 81. Today I added the third fan and the temps dropped all the way to 75 same settings.

I'm very impressed. Probably going to replace my other fans too. Didn't even think about that. Still can't overclock to 1150 past 100 volts though. (I prefer to stay under 100) Although now I think I might be able to add more voltage since the temps are dropping so drastically. I'll try and wait till I can order at least 2 more fans before trying to go over 100 mv. The last time i did that. (before i added the 3 fans) I was hitting 89-91. Which I was not happy with lol.

Dude... I know lower temps are supposed to help stabilize an overclock but that is ridiculous. 1245MHz at 1.24V? Mine won't do 1200MHz at 1.28V. Damn... Share your secrets with me! frown.gif

EDIT : Seeing as it's a particularly cold day (By Greek standards, at least. It's like 10C outside) and the house is like a fridge because I forgot to turn on the heating, I decided to relieve my frustration by benchmarking stuff, so that I could make the best of a situation. Only thing I managed to do is cause me even more frustration. Some of my results are the following : 1200/1625MHz at +125/+25mV, 1210/1625MHz at +150/+25mV and, my personal favorite 1225/1625MHz at +175/+25mV. I was at least happy that it didn't explode, because otherwise I'm ready to throw the thing out the window. Temps didn't break 66C on the core and 60C on the VRM (10-15C ambient, side panel off and fans blasting at 100% does provide substantial cooling it seems), so these aren't the issue. I can't for the life of me explain why my scores go further down the higher I go. There also was no artifacting as far as I could tell. And then there's this 1185/1725MHz at +100/+50mV run that obliterates (ok, I exaggerate here but still) all higher overclocks. Also, my memory refuses to do 1750MHz no matter how much voltage I throw at it. Boom, black screen or RSOD. Kind of ridiculous, really. 1725MHz is fine for anything other than prolonged gaming.

So... Any ideas are welcome. Both for overclocking/benchmarking and anger management.

EDIT 2 : Did a suicide run at 1225/1725MHz at +200/+25mV. Still, no go. 14400 plus change. What the...?

The Stilt has posted info about "ASIC Quality", this post.

There are also some great explanations / other info regarding say LL effect on litecoin forum by The Stilt, his thread.

There's no secret. Its just the lottery. My VRM's are way too hot, otherwise I sure it could go higher on the core. I can't figure out how to get them colder. Thinking about buying a brand new block and modifying it so it will fit this card as its not supported by any block vendors ATM. You're card really isn't bad at all. Good even, mine is just a little better than average is all. There are some out there even better than mine, just the way it goes.

I know it's the lottery. By "secrets", I meant to teach me how to win the damn lottery. tongue.gif

On a more serious note, the only thing keeping me from slapping an AIO or something on my card is that its resale value will tank completely. Or at least I think it will. Maybe I'll change my mind about that as summer approaches. Temps do improve things a lot for GPUs, so I do not think 1200MHz is out of the realm of possibility for 24/7 operation under water. For how long that would work... That's another story. I have no idea how fast voltage and current can damage a GPU, but I tend to think that if temps are in check it's all fine, really.

Other than that, do you have any ideas why my scores suck so bad? I mean, they're not bad per se, but I see marginal improvements over 1150MHz and even a regression in performance over 1185MHz. Is it just that these GPUs hate voltage that much? I hoped not as long as temps aren't the issue...

If you can make it to run at 1750, you are in to a good start. Do a GPU-Z render for a little load to verify Memory Clocks are stable at least.

3. Set Core Frequency to whatever value that allows no artifacts.

4. Adjust fan speed to your preference.

5. Tune down the Voltage for better temps that is suitable for your Overclock.

Oh any special reason it should be +50 power limit always? Never heard aboutt memory straps is that specific speed that has to be? ( I cant put 1635 for example?)
