Seems fine to me. I am getting 10450 with my Powercolor 390 1100 / 1575. I have a 3570k. The 6600k scores about 300 points higher than a 3570k.

Well its seems okay then. Btw I have a question, I followed this guide when i OC'ed my cpu https://www.youtube.com/watch?v=A0zy1TEMiOQ. Everything is fine during the stress tests. But last night I got a blue screen with "machine_check_exception" while browsing steam and my pc hang one time when I was playing AC Syndicate. CPU temps were at 70C when it hang. Is it caused by my overclock?

I'm just chiming in to give some insights. thumb.gif

Memory straps info - these cards have memory straps that you need to target when overclocking.

1375 -
1500 -
1625 -
1750 -
1875 -

With the exception of the XFX DD 290X 8GB where the BIOS litterally don't follow such rule, when you OC the Memory, follow this rule:

Shoot for the strap ends. See above. If you are nearing the higher strap end, say 1620 -- it uses the the timings from 1501-1625 -- meaning, tight timings for the frequency.

Whereas if you are at 1650 - 25MHz from 1625, you are now using 1626-1750 timings. Closer to 1625 than to 1750. Meaning, loose timings for the freqiency.

I am willing to bet 1200/1625 scores better than 1200/1650 that you are in. You can test to confirm. Also, it's not gonna hurt to try 1750 for 3XX Cards seem to do better in memory OC than the 2XX cards. thumb.gif

What are the safe temps on msi r9 390? Is 78C max load fine?

The cooler the better. 78C is better than 90C from ref 290X DEEMED safe by AMD though.

Here's my submission. She looks like a pretty good one as far as 390x are concerned. Does 1230mhz at 75mv. I'll see what it can really do when I get some time. And yes, that's only the cooler as I already ripped it off and put a universal block on it. thumb.gif

Seems like my MSI R9 390 isn't that great overclocker and doesn't like voltage. I tried getting 1150/1600Mhz stable but after I added some voltage screen went black and only way to get it to work again was to boot with safe mode and uninstall drivers with DDU.

At least I can get 1075 / 1550Mhz stable without adding any voltage. I'm happy with that.

did you increase power limit as well

Hello everyone,
Been following this forum for quite a while now and finally decided to get an account since i have a pretty important question.
i've got an asus dc2 390x card (watercooled, dc2 cooler is crap frown.gif wish i knew that before buying my gpu).
Right now i got a stable overclock of 1200/1700 at +100mv so there is plenty of room to tinker with.
However, whenever i try to increase voltage more, say like +150mv, my pc crashes occasionaly. core temps are fine, as wel as vrm temps.
There is also no artifacting when doing this what so ever.
So, i overclocked to 1250/1775 with +150mv. Ran heaven benchmark couple times without a hickup. But as soon as i start to play some games, black ops 3 for example, it crashes after a couple minutes, sometimes half an hour.
Someone who has an idea?
And by crashing i mean black screening tongue.gif

pc specs
i5 4690k at 4.7ghz (not the issue here, is perfectly stable after 24hr stresstest)
r9 390x with a kraken x31
coolermaster g750m psu
16gb 1600mhz ballistix
asus h97 plus mobo
evo 500gb ssd
2tb hdd


many thanks!
pj

Is there anything I can do to have lower temp? Add extra intake fans etc?
