"HD7970 & HD7950 Results Thread - Torture Your Card, Post It Here!"

This interests me too. I could run 3Dmark looping for hours, but as soon as I would start playing I'd get a crash within seconds.

I can second that, but I also have had crashes in windows after the computer has been on for a while.
These never happened while I was browsing with the occasional youtube, it happens when I turn of my monitor (yeah, strange habbit), and go do something else for a couple of hours.
When I come back it takes a little extra time to get back on and I get the message that ATI etc crash.

I get the Display driver has stopped error while on desktop sometimes, guess its a driver problem. Since 5870, I expect driver issues when I buy an ATI card, but the card is a beast for 3d benching so for me its worth it. For gaming I would much prefer using an nvidia card.

Your monitor go to sleep? Because zerocore with overclocking cause driver stop situation after monitor wakes up. on RC11 driver, need to test this thing on last 7970 leak driver. At this time temp solution is disable display off timer in power settings

Problem with monitor resume not working is with the latest leaked drivers.

[GX-BadAngeL]

Confirm. Same "driver stops" issue.

Any have a unlocked bios for Sapphire 7950?
Wonder when the new RBE will come out that supports the 7xxx series?

on my case is related with firefox...

I can confirm this. I switched from an AMD to INTEL rig...format and installed same driver so it could driver related to my monitor?

i have a samsung s27a950d..... 120hz...

add: i have random fliker on 2d mode....

2xgtx680 is on my mind....

@ GX-Bad Angel

Hey, the monitor doesnt go to sleep, I have it set to "Never", but the screen goes black sometimes while im on desktop, and then it shows the display driver has stopped warning/error.

I dont use firefox, Ive been using chrome or explorer.

Try this for flickering 2D and other 2D issues:

Navigate to: "C:\Users\USER\AppData\Local\ATI\ACE\Profiles. xml"
Edit in Notepad and find the section below:

<Feature name="MemoryClockTarget_PCI_VEN_1002&amp;DEV_6798& amp;SUBSYS_0B001002&amp;REV_00_4&amp;2F1C4782&amp; 0&amp;0018A">
<Property name="Want_0" value="15000" />
<Property name="Want_1" value="137500" />

Edit the value
<Property name="Want_0" value="15000" />
to this
<Property name="Want_0" value="30000" />
then save before closing.

This will change memory idlespeed to 300mhz instead of 150... Reported to solve 120hz issues, might be linked to other issues as well.. Crossfire will have two of those entries, one for each card, to be safe change both... This is an old 5xxx "fix", I believe most issues seen on 79xx needs a driverfix, but here you can try changing idle core/mem to see if something works..

Thanks! Ill give it a try.

On another note, thought I had killed the card last night. I was changing memory out, guess I hit the card with my hand, but when I powered the board up, The card was not all the way in the slot. So I get the black screen every time when tryingt to boot, I thought "OH ". Finally switched the card to slot 3 and it booted ok, but the screen would go black at random and lost all function in windows, the screen would turn green, blue, lost icons etc. As a last resort I moved the bios switch on the card, and all seems ok. Then reflashed the other bios and both seem to be working ok. Luckily this was not on the R4E, but the Giga Z68 board, still kind of sucks to have a dead pcie slot.

Interesting! - Its all find and dandy doing benchmarks are super high clocks but if we can't game with them its a bit pointless!. I initially thought it was because 3dmark11 doesn't use up much graphics memory it might be that so reduce the memory speed to something I knew was easily sustainable - i.e. 1575 as per CCC 100% stable overclock. This still gave me the same problem - lockup in BF3 in 5 > 10 seconds of starting a game. I took the GPU clock down to 1150 (I know I can do 1125/1575 100% stable on stock volts using CCC as thats what I've been using from day one) - but was still getting the same until I upped the vcore.

Wierd...... Anyone any thoughts on this anyone?

My thinking was theres no point running afterburner / trixx etc etc to gain slightly better clocks than CCC by having to use more volts aswell, if it isn't gaming stable so have gone back to my CCC overdrive stock volts settings of 1125/1575...

[mR Yellow]

My BF3 runs fine. If you are crashing it's because of too high oC with too low volts.
BTW, i'm using the latest Beta.

Did anyone notice a performance increase with the new BF3 patch?

MSI 7950 Twin Frozr III



In air, with stock cooler : max 1250@1.25v and 1800 for memory
In watercooling : max 1280@1.3v for 3D11 and 1250/1800 for 3DVantage
No LN2 test because no possible for the moment vcore > 1.3v

[lowfat]

Is flashing my HD7970 to an Asus BIOS the way to break the 1125MHz wall? Afterburner no TriXX are able too from my testing.

[Martin.v.r]

got a new form rma 7970 SAPPHIRE

meget fin asci.jpg

1250/1800 1.168v
1285/1775 1.185v
1300/1775 1.200v

Having fun with my Sapphire 7950 OC so far. 1260/1787 @ 1.25v. Tried 1800Mhz on the memory but it caused 3dMark11 to crash about 1/2 way through, might see if I can use afterburner to add some memory voltage to break 1800. Dual fan setup is nice and quiet and cools very well.

What VRM temp are you guys getting with your overclocked 7970 ?

You can check it with newest version of HWiNFO64.

I got a little scared when i checked my temp, on a SAPPHIRE 7970 with aftermarked Accelero Xtreme 7970 heatsink+ fan on auto.




Good thing Accelero @ 100% fan sounds like stock cooling @ 30%, so i made a very agressiv fan profile with temp over 50 degree celsius = 100% fan.

(screenshots was just a test, from before i found my 24/7 clocks. 1200/1750 + fan at auto @ 1.175v + 1.625v)

*edit*

I dont know how to make the screenshots any bigger. So i uploaded them here also:

Although I am running high clocks since I haven't figured out how to clock past 1125MHz. But this is w/ an EK water block.

@ lowfat you need the bios linked from KPC, that one lets the sliders in AB go to 1665 core and 2400 on the memory

[Ourasi]

Here is how to extend clocks in CCC to and Afterburner to 1665/2475 with no unofficialmodes or bioschanges:

Create an Shortcut of MSIAfterburner.exe in the MSI Afterburner folder, and in the shortcuts properties Target box add " /xcl" (space+/xcl without the quotes) and make sure the shortcuts administrator rights option is turned on. Start Afterburner with this shortcut (make sure Afterburner is closed before doing this), and you'll be asked to reboot. After reboot, CCC limits are extended, so are Afterburners, independant of each other. Keep the shortcut, as you'll have to do this after a driverupdate. This will work as long as AMD allows it in future drivers.. Tested to work in RC11



Kudos to Unwinder...

By the looks of things iam not the only one having problems with VRM temp on the Accelero heatsink. (other custom coolers also)

Found this on a other site (I will remove the link if its not allowed to link to other forums)

Getting 95-100c @ 1200mhz + 1.1175v when looping vantage.

The stock cooler is actually better on the VRM's, but its so much louder.

Can't have your cake and eat it too i quess

Hoping swiftech will make a heatsink like this that fit under the Accelero+7970 combo. I would order it in a heartbeat.
