Overclocking the Radeon 6770m in the dv6t 61xx

is the 2gb version of 6700m better than 1gb version for overclocking?

 

I don't think so, but I think the 6770 may (I am not positive) be able to use more than the 1gb if you can pump up the memory clock. But it probably isn't worth the $50-$100 bucks or whatever they charge for the upgrade. I would have ordered mine without the 2gb if I knew what I knew now.

 

thanks
will take one with 1gb

 

Im overclocking for Skyrim. What would be the best to get higher clocks in? Memory or Core?

 

memory seems to increase performance more and it also overclocks easier

 

I have a silly question..my BIOS version is F1.A dated 20/7/2011 according to the BIOS menu..but I don't know how to switch to manual mode cause I can't see an option in the menu!any help is appreciated.thanks in advance

 

you have to go into the BIOS and change from dynamic switching (which is what you are on now) to manual switching

i think the hotkey is ESC to get into the BIOS when the laptop is booting but i could be wrong

it'll tell what the key is when its loading

 

The key to get the BIOS is F10

 

Overclocked mine to 875 / 950 . no artifacting and every app runs well,
Crysis 2 on hardcore ran at 25 fps before. after the Overclock it runs at 40 fps

 

ok at 875 / 950 my driver crahsed once so i reduced it to875/925.

Ran perfectly .

 

If you have a 60xx model, even with F1.A, you will NOT see a BIOS menu option... ONLY with the 61xx. The 60xx series are ONLY manual.

 

ok is frequently switching your clock rates harmful for the graphics card?

i normally keep it at default but when gaming i increase it to 850/900.


I do this atleast 4 times everyday.

I hope i am not harming my card

 

I've been switching the GPUs like nobody business since 6 months ago. No hardware problem so far.

 

im not talking about switching gpus im talking about changing clock speeds

 

LOL! My bad.. again.

Should be no problem IMO. The clock speed constantly changing based on the GPU usage. On idle it will drop to 100/150 IIRC.

 

No, there is no problem doing that what-so-ever

 

hi guys, there is a method to do a permanent clock?
i has been used the Radeon bios editor to do on a ati radeon mobility 3650hd in asus laptop, but in HP laptop i dont know how to extract vga bios file from *.fd file, solutions?

 

Good afternoon to everyone, my name is Richard, I am a new user and I am glad to meet all of you!
I hope you can excuse my awful English speech, but I am a native speaker of Italian. I need your help!
I tried to overclock my radeon HD 6770m on my Pavilion dv7, but when I try to modify "MSI Afterburner.cfg" a window told me that I cannot modify the file because tha access to C:\ etc was denied!
What can I do to solve this problem?I am sure I logged in with Administrator account!

 

Did you open notepad with administrator privileage? Right click Notepad in Start Menu and choose Run as Administrator.

 

Ok, at 875/950 and DNA 11.8.3 i get stable performance and counter strike on the highest possible settings runs at around 50fps.
With fraps recording it goes down to 25~20.
No artifacting or any other issues.

MAX GPU temps = 75 though the average was 71.
MAX CPU temps = 87

 

I followed the instructions but when I click apply in afterburner it resets the sliders to 0. Is that correct? I don't see any change in CPU-Z for the speeds either.

 

^ Are u using dynamic switching?

 

yuuupi!!! LOL
I discovery a method to Dump the VGA bios file from FD bios with a tool call'd Phoenix_Mod_Tool_1.42, now i have my GPU with definitive overclock!

 

^ w00tz.. can u overvolt too?

 

Yes Dynamic is selected in the BIOS

 

Ok guys.
With Original Hp .3000 + DNA 11.8.3
OC @ 850/950 in performance mode = FREAKING TEMPERATURE !! Manage to run furmark for 10 mins and temperature hits 90 C !! Somebody please help me out !!

 

You need to use Fixed to be able to overclock the GPU.

Sorry can't help you.

 

LOL ! Can't help ??

 

With cooler? with TurboBoost on?

 

It was on Performance mode in coolsense. And high peformance in powerplan !

 

set it on Coolest to disable TurboBoost.. without cooling pad? try to raise the laptop with book or something..

90c is CPU temperatures or GPU? If GPU i don't want to know what your CPU temperature is.

 

YEAH. DID THAT. Btw 90c in furmark !! -_- And I believe its GPU's temperature !! Is it something wrong with OC or driver ??

 

Neither Trixx nor Afterburner will let me change the voltage. They're both blank. FurMark correctly reads the voltage at 1.050V. Afterburner has "Unlock Voltage Control" ticked and Trixx has "Disable ULPS" unticked. What do?

What is the temp when not overclock?

You can change it with Trixx but need to use 11.9 driver and below.

 

So anyone know if the voltage will continue to stay locked for all future drivers (like 11.10-11.11)? Cause I think that means I'll be stayin on 11.9 for a while.

Stable OC:
Core:870
Memory:1075
Volt.:1053
Temps: 80-81C (Coolsense on Performance)

Have yet to push the gpu to the point where it stops being stable. I wish I could run 3DMark, but ever since I swapped my HDD for SSD all of them fail to run with some system info errors....

What clocks/temps are people using?

 

OK. Cool sense in coolest mode. CPU in 99%. OC 850/900. Furmark result 78C/79C !! Should i try pushing the memory alil bit or stick on to this ??

 

Whats your temperature while running furmark ??

 

Oh, in fixed mode how does that effect the computer useage?

 

Yes because the we mod the bios with a tool Radeon bios Editor wich iss possible manage all things of grafic card

 

I'm not sure.. the display will flickers for 2-3 secs when u switch the GPU. It is seamless in Dynamic mode.

Naise.. wanted to try but i afraid it will brick my laptop.

 

Excuse me if this is a stupid question, but when using msi afterburner I save my oc to a profile but it seems it doesn't save the oc and just goes back to default clock. Any help and sorry if this has been discussed before.

 

I think we HP notebook owners are lucky for Recovery crisis, i already done once because change voltage from RBE, and my notebook didnt accept ....search for: undocument insyde bios recovery

 

with my very old dv7 2000series with quad core q9000 and hd4650, im getting almost 8k on 3dmark06, and temps with gaming never pass 80ºc, and in idle 39ºc

 

SO I just ran the test, and got some entertaining results. SO with the mentioned oc of 870/1075/1.053 the max temp on futuremark went up to 85C which is higher than in game in BF3 where I saw 80-81 (a max of 82, but only for like a second every some 10min) but since this is a burn in, that's not really all that surprising. However, as I'm watching the temp slowly creep up above 80-81, I'm thinking that the laptop feels significantly cooler than it did in BF3. This not too suprising either since BF3 uses the CPU ALOT (6-7 threads....yeay for quad core) which would generate alot of extra heat (furmark seems to only care about the gpu)

Here's the entertaining part (and note this is on performance setting on coolsense); as soon as the temperature reached 85C the fan revved up and the temperature started dropping and after a min or so, it ended up at 82C (the max I had ever seen in BF3). So I guess 85C is the magic temp that coolsense waits for before going full blast on performance (or maybe it monitors the cpu temp at which time it reached some other 'key' number...but I doubt the coincidence).

So ya, max temp 82C (though it did reach 85 before the fan went full blast). Also note that the laptop is on a zalman nc1000 cooler and currently has the extended battery in (allowing more airflow...though not sure if that's actually helping since with the normal battery there could be more air hitting the laptop directly from the zalman....gonna test regular battery next, but I don't expect any large changes).

 

Quick update:

Without the extended battery, the temperature pretty much immediately dropped down to 81C, at which point the the fan slowed down, after which the temps went up to 88C...and the fan still wouldn't go full throttle. So, max temp got up to 89C (stayed at 87-88C 99% of the time), but the fan wasn't at max. This strongly suggests that the fan is not controlled by the gpu temp but by either the cpu temp or the avg of the two (or some other abstract algorithm hp decided to implement). I might try the same test but with coolsense set to coolest mode.

 

Quick update 2:
So as soon as I hit apply in coolsense to coolest mode, the fan went full throttle and the temps started dropping. Within about a minute it went from 88C to 83C. After sometime the temp kept fluctuating between 78-79C.

 

u mean u failed to overvolt from BIOS mod?

Mobile SandyBridge is very hot. Our GPU is not as hot as GT555M tho, else everything will get way hotter because of the shared cooling.

Go into Settings and Assign which profile to use when 2D and 3D.

 

so BF 3 temp goes upto 81 to 82C right ?? Btw whats ur current FPS in BF3 ??

 

It does seem to depend on the stage, but I've been playing alot of metro where the fps tends to be 24-32, but sometimes it does dip to 21 sometimes (this is in 32v32 matches on 1080p with everything on Ultra but no AA)

SO just avg some samplings from a 10min game in metro map taken every second. OCed at 865/1105/1.054 with coolsense set to performance, I got an avg of 74.5C and 27 FPS
