Ok had nothing but problems finally got everything working and now suddenly...

When i load a game. Uengine Valley, or anything else which uses my GPU's only my gpu 1 is working. my gpu 2 stays at Idle 300mhz...

Why?

Thanks for reading.
 
Disable ULPS in regedit.
Go into the AMD CCC for Crossfire, is it definitely ticked (When I ran a 6870 Crossfire, it used to love deactivating)
 
YO Martini! GPUz seems to not show its bumping up to equal usage as gpu1.
but msi afterburner is so maybe a fault in gpuz ?

Got my haswell to 4.5ghz and uncore 1:1 ratio! with a 1.25 voltage
I needed 1.375 for 4.6ghz and i didnt think the rise in temps was worth it so im happy with 4.5ghz!
 
Remove Msi afterburner..
install again...
Disable ULPS and restart (if it is already disabled you should enable, restart, disable and restart again).


Are you sure your CPU is stable [email protected]?? because it is weird that it needs 1.375V for 4.6ghz and only 1.25v for 4.5ghz... try [email protected] just to test.
 
Ye very stable! Heat as low as 68 under full usage. If it boots my comp and I can play games with no issues I'm happy. What would 1.3 do for me? How would that benefit me now if everything seems so stable!?

And my cards were working lol I figured out crossfire doesn't enable unless in full screen and I was trying to test the hpu2 usage while in valley basic. Which isn't full screen. Went into extreme HD and came out and msi showed that both cards peaked to 99%
 
I watched a tutorials from some one at Asus guiding you threw to over clocking haswell on my board. And he says he sees this all the time... Some people can go to 4.5 with 1.150 and some people need 1.3-1.4 and also you can suddenly hit a ghz which your chip just won't tolerate So I don't think mine likes anything over 4.5 ill try 4.5 @1.3 and see if I get any improvements in benchmarks? What do you think?

"Of the processors Asus has tested, 70% hit 4.5GHz, 30% reached 4.6GHz, and 20% made 4.7GHz. Only 10% were stable at 4.8GHz."

"
Here are my results before the Delid\ stock TIM on a noctua nhd14 with 3 fans

4.6GHz @1.35V 3900MHz ring bus max temp 90c"

And a lot more comments on the web to suggest mine situation is normal.

But mine was better temp at 4.6 1.35 I had max of 80! But I'm happy at 4.5 I'm not out to show my chip off, just want max performance with max stability

I use Intel Burn Test to check for cpu stability. If you pass 20 runs of the very high preset in my experience you're rock solid stable. For the love of god make sure you have a good cooler installed on the cpu before you run it though and be prepared to stop if temps get over 90c.

Click to expand...

1.3V was to test if it could be the problem.

my pc can boot at 1.26V, I can log on windows, can run games, can use stress and benchmark tests without problems but if I try to watch a video only on Internet explorer the computer freezes... with 1.28v it runs ok.

So sometimes you think your computer is stable because it is running games and other stuff, but you get some weird problems and could be the overclock.

P.S.: Yes, crossfire only works in fullscreen
