post #671 of 4099
anyone got 7850 over 1250/1450 stable? it seems that's max for my MSi R7850OC.
it's @ 1.185v (10% more than stock) and Power Tune is on 10% (not stable without this, crashes after 1-15min).

max temp is 75C after 2 hrs of BF3.

I made it perfectly clear that it was a widespread problem, and I will reiterate it, but I will also do my best to cooperate with him to filter out any simple causes of this voltage spike situation.
For all I know, this voltage spike issue could be entirely related to version 0.6.0 of GPUz (doubtful because it happens in AB too), or it could be related to the sensors themselves specifically on the the HD7870. The truth is that I dont know, and apparently neither does anyone else here. It would be much more rewarding to help the support tech help me, than to just tell him that everyone else has the same issue, especially if some fix can be found. In effect, I hope to find the cause of this issue with Sapphire support, and hopefully any fix that they can come up with can work for everyone else as well. Wishful thinking, I know rolleyes.gif
I have a feeling that he is just going to suggest I RMA the card, which I really don't want to do, but I have a feeling that is what the result is going to be.
It can be frustrating, but I have hopes that being compliant, and going "through the hoops" will benefit myself, and everyone else with this issue. After he mentioned using the card in another system, asked if I had another card (because my components are brand new). I said I have an HD5770, and I could put that back in and test it to see if I see any spikes.
It will be much easier to swap the card, than to put a system together, and load my games onto it just to test my new card.

We understand the situation. It's just that this seems like is going the typical "can't figure out your problem" line. Problem → try this → not working → RMA → new card → same problem.

Hope this is not the case. We appreciate your time for making the consult. Keep us informed thumb.gif

Has anyone with an MSI Twin Frozr 7850 managed to unlock the voltage and run a stable OC?

Actually MSI AB version 2.2.0 is supposed to bring full support to the program for hd 7850 and other 7000 series. Although, When I try to run AB it crashes my system. Many people on the AB forum are reporting this problem with the new AB version. I was unable to test is the unlock works with 2.1.0 since MSI removed completely the 2.1.0 when they release 2.2.0 frown.gif

Mycard works perfectly with AB 2.2.0 final smile.gif just dont install Cat 12.4beta....its buggy for me. My little brother always had problem when playing PES 2012, it often froze and sometimes watching movies also froze. Roll back to Cat 12.3 WHQL works normal again smile.gif

Just got off the phone with XFX. Tech support said it is normal with the architecture due to the card throttling the clock speed higher (even the 1.998 V spike that I am seeing) . They said to disregard voltage spikes as long as you stay below 90 C then you are good; this is with me telling them I am sitting at 1.3 V 1300 Mhz.

Not sure if serious.... or if I am just ignorant.

Getting the same crash with 2.2 AB here on a XFX 7850 BE.

I was thinking a 7850 because it would be hassle free to crossfire being they are such low power cards.

They do overclock rather well yes.
If you are going to keep it with 1 card i would stay with the 480 though, its not worth the money for a sidegrade.

Yeah, I hope that this isnt the case, I would hate to have to RMA my card for something as silly as this.

Well that is curious... Curious indeed. I wonder if XFX is saying its normal because it is, or if they are saying its normal because they don't know why its happening. To simply disregard a voltage spike of 1.9v on a 28nm core seems silly to me. I would think a spike that large would instantaneously degrade the core. If you put 1.9v into a CPU, especially on air, bad things would happen....

You can post or PM a few results though and i might use it.
Would be nice if you can clock your cpu higher then 4,6ghz though.
I plan on doing all benches on 4,8 or 4,9ghz.

I can do 5.1Ghz but I think results using closer to stock or common speeds would help people if this were for beneficial purpose for a larger community. Maybe we can compare our results later using 5+ ghz clocks and see what best average speeds are. Input?
