ATi Catalyst 10.5 Released - Official Thread

69c is nothing for a GPU, I have a feeling a touch of the placebo's may be in affect with you...

 

Default run, no settings changed.

I've found today another strange bug: if load a game and an hardware accelerated video, the powerplay set my card at 400/900MHz UVD profile, not the max overdrive clocks! :3eyes:

 

Some of the phenom II's are extreamly touchy with overclocking, and require quite a big voltage jump

My 955 goes to 3.5ghz stock voltage, but to hit 4ghz I need 1.4625 volts, which is a huge jump, but I've heard horror stories of 955's needing 1.45volts just to hit 3.4-3.5ghz

 

I read that the absolute max for 65nM is 1.5V but your temps must be in spec.
On my 45nM Quad, without reaching the max voltage, I need water cooling.
My old 45nM Dual core was fine with a TRUE120.
The last +5% (+200MHz) CPU speed on the Quad needs 16% more power!
(1.3V to 1.4V, absolute max voltage is 1.45V on 45nM)

Note the op is trying to overclock from stock speed by adjusting the multiplier, unless he has an unlocked multi, this wont work.
He shouldnt have hit a voltage/heat wall yet.

 

anyone in here play race on by simbin? I have terrible stuttering in that game now.

 

Really? I heard it was something like 1.3625v according to intel

 

Yeah thats the official figure for a 45nM CPU to provide decent service life in extreme conditions.
There is a bit of room to play with.
We're talking voltages that shouldnt be exceeded else something traumatic might happen pretty quick and a good long term max voltage without incurring too much wear.
Temps must always be kept in check of course, I stick to less than 70C.

I ran an E8400 at 1.4 to 1.41V on air (TRUE120) for about 1.5 years without a problem and tested it up to 1.45V in its early days.
Its still as good as day 1.
My Quads been up to 1.45V on water as well (damn it puts out some heat) and it hasnt changed its overclocking characteristics so it looks safe.
Currently running the quad at 1.4V for 2 months now and loving it

 

I wouldnt go above 1.4v on a 45nm myself

 

H all

Just bunged the 10.5 drivers on my setup (5970), got the same 400/ oc mem clock like everybody else but have more fans than a wind farm so temps aren't an issue.

No issues as regards perfomance, everthing running pretty much as it was before.

What is has done is unhooked the fan control and monitoring from Afterburner, have uninstalled/reinstalled CCC & Afterburner and faffed about for ages, to no avail.

Fan Control remains blanked out and fan speed sat at 30% regardles of what its actually doing, even in game when I can hear the fan ramping up the osd says its at 30%

Odd thiing is, I can go to Afterburner settings and create a custom fan setting and it will use it, yet still report fan speed at 30%

Didnt have any of this with the 10.4 drivers, anybody else have this issue?

Cheers, Mart.

 

Its not temp related, see posts #43, #66

 

official 10.5. (and 10.4) gave me really poor performance in CMR dirt. Latest beta (8.74) solves the issue. So for me 10. 5 are no go. Love the old dirt :nerd:

 

Well it had to happen sooner or later, been fine since Cat 9.11.

10.5A Caused random crashes, jittery games and clock speed problems, tried rolling back, damage already done. Had to reinstall Win7.
Now running great on 10.5A.

LeSigh.

 

Did you use a driver cleaner?
Did you ask for any help online?
Its extremely rare that a Video driver causes problems so bad that they cant be easily fixed.
I havent seen any other reports of 10.5a hosing PCs.

Do some stability tests to make sure your hardware is ok.

 

Is there a "Best" driver for running in Crossfire? Old or new?

 

Tried 10.5 WHQL drivers and had problems with it, but the 10.5 Hotfix driver is working perfectly for me and the long loading times in BC2 are gone. :O

 

Often its the latest driver but best to read release notes and forums to see what performance others get with your hardware etc.
It can vary with different games, different resolutions, different gfx cards and different OS's too.

 

Yeah it will do that but you will lose your 3D overclock setting. Now both 2D and 3D will read 157/300.

 

1- Yes used driver cleaner
2-No
3- Prime95+Memtest+Furmark OK

It must have been the exact mix of drivers/programs i had, one in a million, as i said everything is fine now.

Most annoying was i couldn't shut down, monitor would go off, windows would look like it had shut down but GFX card fan was running at 100%, hard-off was only option.

I tried numerous fixes, format was only answer.

 

Understood that you had enough, theres been a few times I've re-installed rather than spending twice as long troubleshooting.
Its good to know the cause, but time/patience sometimes isnt a luxury.
I'm glad you are stable.
