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

[HelixPC]

i need to know why if i overvolt only the card crash @default speed......

my card did this as well. But i had another card next to me, tried that one and it does 1250mhz core with 1.25v set in MSI AB. So it all depends on the card, some like voltage some do not, weird.

[aussie-revhead]

Helix - did you try both at max volts but default clocks? I think thats what Andrea is asking.

[zpaf]

First and success try with Trixx at 1.3v on air.

37.5 + 30% = 48.75





Please do not ask about driver.

I have an Asus HD 7970 and it won't do 1300 @ 1.3V so I tried to do 1250 @ 1.275V but it artifacts like crazy. Anyone else think putting a waterblock on it would make it stable since it should be able to cool the card better? At stock volts it does 1150 easily.

really intrested in getting one of these cards waiting for april thou when ivy bridge is here.

[aussie-revhead]

My Sapphire does 1165 at stock volts with fan on auto, and does about 1270 at 1.3v with fan turned up, yes that droops to about 1.19-1.21v under load.

Hey guys anyone having problem with trixx setting back your over clocks to stock settings

[pinto]

Max frequencies with stock cooler, wait for my EK block to arrive. I don't expect much improvement without more volt...

[OC Nub]

^Nice clocks!

Trying old benches now. Ran this in w7 64.

I used trixx, didnt like it too much, i prefer MSI AB, you can also monitor temps, volts, fps etc.....

thanks man let me try , what refrence designe are you using helix

I have a Diamond model, which is a very good overclocker, doing 1.250ghz core, 1.725ghz mem with 1.262v set in afterburner. I did test a Sapphire card that i used for a build for a customer that did 1170 core on stock volts, it would crash tho once i raised voltage, lots of people are reporting this issue, seems to be a hit and miss with cards that can get over 1.2ghz.

have you played any games? 3dmark is not a good stress test for this card, try cysis 2 with dx11 patch and high res texture pack, cod mw3, bf3.

My card is a Sapphire and i can raise the voltage up to 1.3v without any problem...

It's not the purpose of my post, i'm here only to show my max OC. I play BF3 at max CCC, Crysis is too old to have interest now and MW3 seriously m8 a poor graphic game like that is an offense to the 7970?

@ HelixPC, The name of the thread is "HD7970 Results Thread - Torture Your Card, Post It Here!' I dont think everyone is shooting for 24/7 stability..

@pinto, are you using the Asus software to clock the card? My mem wont get near those clocks with afterburner.

[pinto]

I use trixx, it's works well!

[hokiealumnus]

Nice clocks pinto! Does TRIXX have some sort of memory voltage control I'm missing? Even with ASUS' software I can't get that kind of mem clocks.

[andressergio]

My Rig just got rebuilt its not fully finished probably around 89 percent but i had to test My new two asus hd7970 , and i gotta say for not really pushing and staying in cc boundaries , this cards are monsters and make my 6970 look slow in comparison , they run cooler , run faster , and overclock like and bunch of nerds in the playboy mansion . . . I think Ati cough AMD has got some footing

Rig Rebuild damn look at those shiny B@#$% beauty's 7970s

u got some really nice powa there Tony congrats

altough i aint fan of ATI lol !

No mem voltage control only more range than AB (I was limited to 1790 with AB). The gpu voltage drop identically as AB, sets to 1.3v give 1.21v load...

[Martin.v.r]

where can I unlock gpu in msi afterburner ,to more overclock ? max is 1125
I use 2.2 10 beta

[the_real_7]

u got some really nice powa there Tony congrats

altough i aint fan of ATI lol !

thank man ! ! ! you non Ati fan lol . . . kepler around the corner no worries Sergio

""Afterburner Beta 11 will be submitted to MSI soon. Changes list includes:

- Added memory voltage control for reference design AMD RADEON 7970 graphics cards with CHL8228 voltage regulators

- Now MSI Afterburner displays target VID instead of real voltage sensor reading on "GPU voltage" graph on graphics cards equipped with CHL8228 voltage regulators. These changes are implemented to avoid confusing the beginners and prevent the hysteria about voltage drop on AMD RADEON 7970 series graphic cards spreading across different discussion forums. Experienced users, understanding the difference between target and real voltages, may still unlock the previous real voltage monitoring mode via editing the hardware profiles

- Core and memory clock limits have been extended to 180% on AMD RADEON 7970 graphics cards in unofficial overclocking mode
- Now MSI Afterburner's startup daemon routine precaches VRM I2C registers state at the first Windows startup. Precached VRM state is being used to detect default voltage instead of hardcoding default voltages into the database. Please take a note that you may forcibly perform precaching later with command line switch or disable the precaching at all via configuration file if necessary and force MSI Afterburner to use the previous hardcoded database based default voltage detection
- MSI On-Screen Display server has been upgraded to version 4.3.1. New version gives you the following improvements:
o Added workaround for AMD OpenGL driver context switching issues causing abnormally low framerate in ID Software Rage when OSD is enabled
o Added workaround for AMD OpenGL driver PBO issues causing the driver to crash or perform abnormally slow during videocapture


The main reason of releasing new version is highlighted in bold. I'm tired of seeing lamers badmouthing current version of MSI Afterburner because of it "incorrect" voltage control causing "voltage drops" in different forums. Now preceise voltage monitoring from real sensor is simply hidden from users's eyes and you see traditional target VID monitoring, which was available in the previous graphics card families.

whit Trixx is it 1300
gpu test,not mem
org on air
SAPPHIRE
1.225v 1275/1600


next ?more test

[OC Nub]

You have a very nice clocking card. I tried trixx but Im still limited to 1700mhz memory.

It ned more vgpu whit 1275/1850 1.275v
