M15x GPU Overclock Thread

Could it be because you use Vsync and your monitor is at 60fps?

 

Haha now I feel stupid. I didn't really realize what vsync was until now. Is it better to have it maxed at 60? Or turn off vsync and let it go higher?

 

Eh, how do you even overclock with CCC?

 

you can't oc with ccc. you have to do it with amd clock tools.

 

imo it's better to have it on when not benching.
off for benchmarks and meters, on for best quality.


using vsync adds a minor performance hit, however the overall fps is more consistant which usually results in a smoother experience. For example dropping from 220 fps to 30 in an instant is noticable, whereas a 60 to 30 fps may not be. people with extremely acute perception might be able to pick up both.

the screen tear effect is because the fps is not in sync with the monitor and you're seeing two simultaneous screens (or more like 1/2 of one and 1/2 of the other)... this is why it's only (usually) noticable during scenes of extreme movement.

 

Yes you can... 10.6 let me. It's called ATI Overdrive I think and it is the last option in the drop down. I downgraded to dell's official driver, though.

 

Curious - how'd it go mb67?

 

my bad forgot its a dell 5850, hehehheh. did you have overdrive and amd clock tools at the time you were having your issues?

 

Nope. I had Overdrive and Rivatuner. Overdrive would get shut off when I wanted to use rivatuner.

 

seems that overdrive has conflicts with other oc programs. i tried overdrive and had amd clock tools and it was acting very strange also.

 

OK this might sound dumb but I'm still kinda new to the whole video card over clocking thing.

I have my computer running on high performance with stealth mode off. I used ATI Overdrive to OC the card to 700/1050 and when it runs smooth without any problems. But when I'm not gaming (2D stuff), it only goes down to 450/1050. For me to get the video card clocks to go lower I have to turn stealth mode on and then it goes to 100/150 or 300/400.

Is this normal or should I do some bios flashing to get the clocks to be on 300/400 when I'm doing 2D things and it'll go up to 700/1050 on 3D stuff. I don't really wanna to be in stealth mode cause I feel as if the computer slows down more than it should be. I just don't wanna burn out my card with it running at 450/1050 all the time.

 

thats sounds strange, so the memory clocks won't downclock?, are you turning off overdrive when not gaming.

 

Overdrive doesn't have an option to turn it off... Unless there is one I don't know about.

 

see if you can uninstall just the overdrive and powerplay. then use amd clock tools to manually change the clocks. i don't have overdrive currently so i don't remember if there is an option to disable it.

 

I think I solved it.. I just disabled CCC from starting when windows boots. Now the clocks adjust automatically based on what I'm doing. I guess I'll just open CCC right before I start gaming so it got to the 700/1050 clocks.

When you use ATI tool, do the clocks stay where you leave them even after you close the program?

 

yes it will still stay at those clocks until you change it again.

also amd clock tools and overdrive don't work well together.

 

what is the correct ratio for ocing 260m??

 

Hey guys, i've downloaded rivatuner.. but for some reason, i dun see the "fan" tab.. can anyone tell me why? :/

 

umm.. i have a problem here, hope someone can help me
i just installed the amd gpu clock tool 9.8
and when i run it instead of the program to run i got this message popping out
"Failed: no valid devices found!", is the version im using not compatible? im using hd 5850, thanks before

*edit: i just changed the clock tool version to 9.26 and it works, old stuff does work!

 

did overdrive option disapear a few driver versions back as in 10.6 and 10.7 i dont have the option, or have i missed something?

 

Hello,

Still quite new to the gaming world. I have had my laptop just over a month and I'm curious about OC.

Will this void my warranty
Which OC tools should I use
What is a recommended OC limit for everyday use

My spec is ATI 5850 GDDR5, 720qm, 4gb ram

Thanks for any help.

 

i spoke to many techs about this and they said it was fine, actually one of the tech told me to use riva tuner,lolz.

for ati card, amd clock tools is good and very simple to use, but you may have to try a few different versions, some versions don't work with your card.

 

Just for fun I'm going to overclock the GT240M I have in the system right now.

Stable for the core clock is between 650 and 675 (default 550).

I'll post more about it later.

 

Thanks inap,

From game.amd.com, they have AMD Overdrive. Is this the AMD clock tool to use.

 

This is what people use: techPowerUp! :: Download AMD GPU Clock Tool v0.9.26.0 For HD 5870

 

The Revelator, always to my rescue. Can I use this on 5850? Have you used this product?

 

yup thats the version for the 5850.

overdrive and powerplay depend on the driver, if you use those then do not use amd clock tool because they will conflict which each other.

and yeah rev is the man. he knows everything

 

What little I know I learned right here.

 

Just clicked onto the link, download. There is no GB option, shall I just choose USA, plus theres USA-1 or USA-4

 

yeah any one of those would work.

 

Thanks,

Did you install the Advanced Micro Devices Systems whilst installing the programme?

 

Yep, but there's a trick with the 5850. If you're using PowerPlay, when it downclocks to the idle setting of 100/150 it also reduces the voltage to 0.9v. If you try to overclock to higher levels (sometimes even 750/1050) it will crash. If you first increase the voltage to the maximum available (1.0v with stock vbios) and then set the higher clocks, you'll be OK.

 

Right, my engine clock is 99.99 and memory clock 150.00, voltage 0.9V

 

Any of those links will be fine.

 

Will increasing the voltage harm/damage any parts?

 

hey rev did you do anything special to your 5850 bios, i should be getting that card in a few days.

 

Nope. I routinely run at 1.10v to support the higher overclocks. we use 1.15v on many of the 5870's. You'll be perfectly safe at 1.0v. That's the stock setting for the standard 3D clocks with the stock bios.

 

Also, What is a recommeded setting for good, reliable everyday use?

 

Mostly just changed the clocks and voltages around so that you have the benefits of PowerPlay, but can still spin up to your highest setting. There is one change on the last page/section of the vbios that you need to eliminate a clocks ceiling included in the stock vbios. I'll make a screenshot of the before and after settings. I haven't seen anyone else mention those limits, so it may not apply to everyone, but I couldn't increase the core above 800 until I made the change.

 

oh sweet, that would be nice. after the card gets here i still need to wait for a mobo replacement or a whole system replacement too, geez. thats my luck for ya. hahhaha

 

We've been hard on our motherboards lately. Here's the shot:



I needed to move those two sliders back to zero (far left) before I could go above 800 on the core. The memory is already set to 1200, but since I haven't approached that yet, it didn't have any effect. Worked for me, but the fact that I have not seen it mentioned by anyone else makes me wonder whether it is needed generally.

Sorry about the quality. That's just how RBE looks.

 

wow thasnk for that, i nevered really check all the options for RBE yet.

 

Didn't need to. All the Clevo vbios's are already set to 0 in that section.

 

GT240M stock: 550/1210/790

My OCCT stable clocks: 650/1470/930

Now I'll try out games and see if it can maintain perfect stability in things other than OCCT.

Edit: so far 630/1450/910 is perfect in games. The other clocks are still stable enough for benches if I were to run them though.

New record for 5850?

 

nice score idk if its the record or not though

 

Hi Revelator,

I don't have that screen on my ATI tool. I just have the options to increase memory, engine clocks and increase voltage to 1.0.

What i'm going to do is manually set the clocks before playing a game, then reset them when running normal activities like surfing.

Why are my settings only set at 99.99/ 150, seems very low. Do they automatically enhance when palying games?

I think a stars coming your way, lol.

 

Guess who just joined the 10k club!

 

Congratulations, Zswickliffe. Welcome aboard.

 

That screenshot is from Radeon Bios Editor (RBE), a utility used to edit various components of the video card's bios, most notably clock speeds, as a prelude to flashing the card. It is completely separate from AMD Clock Tool.

The 99.99/150 clocks are the idle clocks set by PowerPlay. It automatically increases both clocks and voltage to 3d levels (625/1000 stock) when a 3D application (games, etc.) is encountered. Clocking down on idle saves power and facilitates cooling. It's working just the way it's supposed to.
