Hi

Can anyone confirm if this has been fixed in the latest CAT's ? I am still seeing massive FPS drops in COD4 for example.

I know there is a fix in flashing the cards BIOS but I really dont want to go down this route and would prefer if ATI just sorted it in the drivers (if possible)

Anyone confirm this or have an opinion on it ?

Cheers

Rivatuner, monitor the card, load a game play for a while, exit the game look at the chart, if the GPU core speed is dropping down to 300Mhz in places then you have the powerplay issue.

Yeah , tried it , it is dropping in places ..........

Surely EVERYONE with a 3870x2 has this issue so ? Or is it only certain games perhaps causes it ?
 
It is usually in certain games when the GPU usage drops below a certain threshold (mainly in older games, but also happens in Crysis, CoD4 and UT3 i've seen).

When it drops below the threshold the card drops into 'low power' 3d mode, which has the same clock speed as 2d mode, as such the game 'stutters' or slows down very noticably.

Then when the GPU load goes back up the card switches back to full clocks and the game speeds up again.

Giving very 'unsmooth' stuttery gameplay or large fps drops in certain places.
 
it is frankly a ridiculous oversight. I guess in benchmarking its almost unnoticeable as, well benchmarks are designed to put a max load on. but in real gaming if you stop to think about where to go next, check a map or something it can kill the load on the gpu.

I can't even get 8.3's to install correctly at the moment. I think mostly its a pain completely installing with a 790fx amd chipset as the uninstaller/installer wants to install/uninstall various chipset stuff aswell which randomly seems to screw stuff up.

Why amd mixed gfx drivers and chipset stuff i will never know. This setup makes it almost impossible to put new drivers on, mostly because I'm using raid so chipset drivers changing makes windows install unstable as heck and default vista drivers don't see raid on the 790fx chipset which is a pain. I uninstall JUST the driver and i get bluescreen on reboot, i uninstall cat manager, CCC and driver, bluescreen on reboot. tis ridiculous.

AS you said, flashing bios, i don't know how easy it is or not, especially without a damn floppy drive anymore and with programs to make bootable flash drives on large flash drives few and far between its ruddy difficult to boot to dos.
 
I agree, it is a problem that shouldn't exist, why ATi don't just change powerplay so that it can't go into lowpower/2d mode when in a fullscreen 3d application I do not know.


However if you do want to do the flash method and fix the problem it is a 2 min job, there is a thread on how to here:

As for getting into dos to flash, easiest method i've found is:

http://www.ultimatebootcd.com/download.html

Download, burn to CD, you can boot to just about anything also recognises flash drives.

So boot from that, then flash from your USB drive :)

I'm really disappointed that they haven't fixed this, I really cant be bothered to flash my card. A simple option to disable Powerplay is all we need...

im getting this, so any ideas how this powerplay thingy is fixed or is it a bios flash on the cards

When you go on the Uninstall wizard on 'ati uninstaller' can't you click 'custom' and then untick the chipset drivers so they're not uninstalled?? ...

Just 'unticking' no?

you can stop it by using rivatuner load clocks on windows boot option in the low level overclocking tab.

Doesn't work.

Riva tuner can only clock one of the cores, so you are only fixing one GPU the other will still drop down.

Also if you fix it in Rivatuner you have to run full 3d clocks even in 2d mode.

thats what i try. I have no idea how i got the 8.2's installed, i uninstalled the 8.1's like that, custom, only the drivers and ccc part, nothing else, reboot, blue screen, system restore, uninstall 8.1's the same way and install the 8.2's before reboot, seems to get back to windows but not really recognise drivers so reinstall the 8.2's and it finally worked.

This time same deal uninstalled the 8.2's only the relevant parts, blue screen, last known config worked this time(didn't last, system restore takes ages as that damn vista dvd is SOOOO slow getting to an installable point, i have no clue why its sooo damn slow). at that point the 8.2's were back, uninstalled them, installed the 8.3's before reboot, rebooted, said no drivers installed, tried the 8.3's again at that point and every single time it just said during the ati driver install part that the inf was not found and it failed to install. Completely baffled, no idea why any of it is happening.

It has to be doing something other than whats listed in regards to installing/uninstalling. never seen this issue with an ati install(or nvidia for that matter) over the past 5 years. But this is first time i've used an ati chipset, why they intergrate any part of the chipset drivers with the gfx drivers i don't know. especially as the uninstall seems to do something other than what it should be. Ever so slightly more complicated by the raid issue and windows not being recognised without that installed, although saying that a lot of the bluescreening in all this is after it goes from windows bar loading just before it goes to desktop so its probably not quite that.

basically i have no idea what it is, so i don't know how to avoid it.

Pretty much you'd think, uninstall previous drivers, reboot, install new ones would work, as it always has. but i get bluescreens before installing new ones.


GRRR, finally had a go at another company after they sent off my p35 gigabyte for rma, 5 weeks later i was pretty angry at being ignored so harassed them massively via e-mail yesterday which resulted in credit note and i was told a replacement(abit quad gt x38) was being processed and would be sent out yesterday. So gave up with this hoping i could just do a fresh install with my Q6600 system working again. NO mobo arrived today though, will hope it turns up tomorrow.

This gigabyte board is truly awful, 790fx, i don't think its the chipset, a lot of people are finding issues with this board with phenoms, quite a lot had horribly unstable phenom + gigabyte 790fx setups, but a change to asus/dfi/sapphire/msi and its all stable. Maybe the driver issue is down to dodgey bios/driver/unstable setup in general.

I have been noticing the Powerplay issue when playing Trackmania United, which is massively fast paced and needs constant high FPS. When Powerplay kicks in to give 2d or low power 3d clocks, FPS plummet and it ruins the game.

Using Rivatuner, the GPU also never seems to reach 100% usage either, and hovers around 50% all the time. In fact, my current card seems to offer little if any performance improvement (apart from 3dmark:rolleyes:) over the x1950xtx I sold for this card to replace! ATI need to fix this issue and give me 100% of the available performance 100% of the time when gaming.
 
Can you bypass Powerplay by overclocking using Rivatuner and killing the ati2evxx.exe processes (ATI External Event Utility)?
 
I did the bios flashing to make low power 3d clocks the same as normal 3d clocks, its like night and day. The card virtually sucked completely in some games, it is now massively massively massively improved in all the games it had the low power clock issues.

It was very simple to do, took 5 minutes and is 100% worth it.
