Topic: Power Drain amout issues [Closed~] - page 2. (Read 2151 times)
I have seen both 1 and 2, and apparently the difference is that 1 allows the clocks to change if the card runs idle, for automatic downclocking, while 2 forces it to stay at the designated clock.
UnofficialOverclockingMode = 2 Two, you say... Hmmmm
its most def. not the PSU. 2xhd6870+1090t oc wont need more than a good 600w psu.
freezing means there something wrong with the cards/one of them.
1. check if u connected everything correctly
2. try them separately, w/ and w/o oc

I suggest you use the 1000w in the mining rig, and underclock the memory on both cards to save on power usage.
My 4870 saves 30 watt by underclocking from 900 to 190. You could see similar savings on those cards, giving more headroom for overclocking core, while still being within 1000W.
I suggest you use MSI Afterburner to do the underclocking if it's on Windows.
Install it and go to the installation directory. Open the MSIAfterburner.cfg and scroll down until you find "[ATIADLHAL]". Replace that section with the following:
[ATIADLHAL]
EnableUnofficialOverclocking = 1
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 2
AccessibilityCheckingPeriod = 0
When you underclock then, you need to close MSI Afterburner and reopen it after turning the memory clock to it's lowest. Repeat until you get down to the clock you want.
If you can do it, and the cards remains stable, you can also undervolt it to save on power and heat.

time to throw that miner out the window or take chances on burning yoru house down.
Get out of my thread, Cooling is not an issue, I have a Trench dug to supply cold air, And more
All cards are running full load mining.
Both comps are running win7Ultimate,x86
Both PSU's are RAIDMAX

Have you tested both cards one at a time, under full hashing load conditions? I thought I had a PSU problem too until I discovered one of my 5830's was a stinker and couldn't handle the OC its bros were shouldering. So I clocked the weak link down a bit, problem solved.
I doubt it's an issue with your PSU, but what brand is it? Also tell us more about driver version, OS etc 
Edit: Also what miner, OC tool and so on

The reward is based off of how Much you help me, Only one person will get paid, Minimum payment .1ßtcSo, I have Two computers, One with Dual XFX6970BE's (for gamimg), And my miner wich WAS a Dual 6990 miner, But i sold a card and bought a 2nd 6870 and a 5830, The miner is currently running One MSI 6990@stock core/mem/volt, and One 5830 Running @875core/stockmem/stockvolt,
The gamimg computer WAS running a single 6870BE OC'd too 1000core 1200mem. Running with no problems, stock volt, and could goto 1040 with stock volt
It HAD a 600W PSU and the comp has a 1090TBEPhenomIIx6oc'[email protected].
Now it has Dual 6870's at Stock, because anything above stock causes my computer to randomly Freeze after about 3-10mins (940core 1150mem)
It Has a 1000W PSU. Same specs for comp.
The Miner Has a 1200W PSU, So I was wondering if the 1000W would be better suited to run in the Miner, and have the 1200W in the Gamer, So that it would re-enable me to overclock my cards.
time is nolonger of the essence i am afk
