The Definitive DV6z Llano Overclock and Optimization Guide

The P6 on K10Stat can be underclocked from 800 MHz to 500 MHz without any noticeable slow downs (computer starts feeling slow at 300 MHz or lower). I was able to undervolt my A8-3530mx down to .7 V

 

anyone tried amd catalyst 12.4 beta, says thats the fastest driver so far, i have 6750m dedicated graphics im not sure if i should install it or not...any idea???????

 

Sorry for taking too long to give some feedback about my "problem". But as I mentioned before, I think either my laptop is broken or I am doing something wrong!!!

I took this picture just now and my notebook has been running like that for the last 20 minutes.

Any ideas?

 

I was wondering why manufacturers don't like to leave full control over CPUs, GPUs to customers? Because they try to use all kind of crazy voltages, multipliers, etc...

 

Because most people don't care and don't want to brother? People buy a machine to do work, not buy a machine to work on it.

 

hi everyone! Ive been studying this thread for like three days now cause i'm so eager to learn how to overclock/undervolt,I just want to point out that I've never done over clocking before,so my apologies in advance for the questions that im about to ask.

*would it still cause lockups if i copy a k10stat setting from a dv6z with the same exact cpu/gpu as mine?
*would the repeated process of dropping down the voltage till your laptop errors out cause any damage at all?
*as mentioned in this guide it says i should start at 2.2GHz. I have a
AMD Quad-Core A6-3430MX 2.4GHz/1.7GHz, is a P0 of 2.2Ghz fine with mine?or is it too high?if it is, then what value should I start?

any help would be much appreciated.

 

Every machine is different. You will likely cause lockups if you use someone else's profile, or conversely not fully realize the lowest voltage your system can manage.

There is always a risk with overclocking, but as long as you are careful there should be zero damage to your system. Just don't be typing your term paper and not save it while doing this, lol. Don't run anything of importance while overclocking and in absolute worse case scenario, you may have to Windows system repair or reformat. But this is rare, and likely only to happen if you just try to crank up speed too quickly.

 

like people who buy apple /mac computers, they don't like to tinker with them. rather just buy a new one every few months. lol

 

hi everyone! ive bin reading in to the gpu overclocking using the msi software in this guide but theres not much detail into it unlike the one for the gpu.uhm...if its not to much to ask,can somebody post a link on a much complete /dummy guide for first timers on how to use the msi software to overclock the gpu so i can follow it step by step?

thanks.

Hi.

Do i have GDDR5 or GDDR3 , as gpu-z and catalyst hardware info, contradict each other?

Thanks

John.

It's GDDR5.

See here: http://forum.notebookreview.com/hp-...z-cooling-mod-thread-warning-lots-photos.html

 

Thank`s, any idea what kind of overclock speeds for core and memory with stock cooling?

John.

EDIT: 850/1000 according to your cooling guide.

 

Yes, most can get 780-820 and 850-900 stable. I can run 780/880 all day long. 800/900 is stable 99% of the time, with an occasional anomaly or hiccup, so I just stick with 780/880 because it's stable and good enough. That extra amount doesn't really add anything.

 

I would only overclock if i bought a game i found a could not run at a decent speed, but it`s nice to know there is extra power available.

Thanks for all your help.

John.

 

i have my 6750 running at 780 / 880 all day, everyday

the difference in fps in bf3 with original clock and overclocked is very noticeable

 

Does anybody get thin black horizontal lines on the screen at random times, they appear and disappear, their is only a couple, I am not overclocked.

EDIT : I just clicked on driver update in catalyst and it is downloading v12.4

John.

 

never had that tinderbox..

what i get from time to time is back and white vertical striped screen..

i know its graphic card related... but does anybody know what really is ?

 

how is this 12.4 working for ya ?

 

It does NOT work with AMD dual graphics, install errors, left display resolution at low, I just overwrote v12.1, no good, and then i ran driver sweeper before the install and tried again, still no good, looks like it`s back to v12.1

John.

 

yeap.. been there, done that..

that's why i asked, to see if you had different results

im back to hp drivers...unfortunately

 

Back to v8.9 why? "amd_catalyst_12.1a_preview_win7_32-64" works fine, "12-3_mobility_vista_win7_64_dd_ccc" works but the cpu clocks are wrong , mains 800-1500 , battery 800-1700 ???

John.

 

i always get those same errors with other drivers..

i mean, install errors, low resolution and the catalyst won't show up when i use the right click on my desktop...

i've tried these drivers but with no sucess...

are the performance between those and hp drivers that noticeable john ?

thanks

I am not much of a gamer, but they install for me.

What is your notebook spec?

John.

 

Is anyone having issues with Afterburner 2.2.0 like me? I applied the Eula and UnofficialOverclockingMode and made sure I disabled ULPS, but the Afterburner "clocks" are stuck at 0. I didn't have this problem in 2.1.0, but I can't find the download for it ANYWHERE, they've all been replaced with 2.2.0.

 

Did you go into settings and make sure you selected the dedicated GPU?

Hey. I have a general question regarding K10stat. I have had a stable OC/Undervolt (P6 800Mhz at 0.625v through B0 2.5Ghz at 1.125v) profile that I have been running for awhile (can post if need be) and I have been having problems with freezing. You're thinking "well then it's obviously not stable" and that may be the case, I just don't know.

I have my K10stat to boot on startup, the problem lies if I unplug or plug in the AC then my computer freezes. No bsod, just a freeze. Also, with K10stat running it NEVER shuts down properly. It freezes on Shut down. If I ever want to shut down my machine I have to hold down the power button.

Any advice (besides not running K10stat) would be appreciated. Thanks!

 

Actually, "GPU1", "GPU2" and "GPU3" all listed the 6750m.

I had no issues with 2.1.0 besides the unusual overclocking limits resetting after a certain high clock setting was applied and afterburner restarting and afterburner failing to apply my overclocks at startup.

2.2.0 didn't work for me at all, but it's ok, I've downgraded back to 2.1.0 and downloading it by "hacking" the latest version's link location and replacing "220" with "210". I really can't find any links to older versions of the software.

 

afterburner never worked to applied clock at startup for dual graphic, it will probably work in fixed mode but dynamic is no go.

How is 2.2 not working?

 

I've been getting the freezes lately. If I find anything out, I'll let you know. Is your HD light constantly red now? I think I might have some memory errors.

Edit: This is directly related to K10STAT. I'd recommend disabling it for now. I even upped my voltages by 1 step and it still happened. My computer won't boot with K10 now, it'll freeze immediately when I login.

 

Hi.

Why is my dedicated graphics showing up as "AMD Radeon 6600M and 6700M Series" in gpu-z and cayayst hardware and i am supposed to have an 7690M

Thanks

John.

 

this is normal, they did it with the driver sometimes ago

 

I reader on notebookcheck that an 7690m is really an 6750m with a extra 100mhz memory speed, but my memory speed is at 800mhz should it not be 900mhz , so do i really have an 6750m and have been told it`s an 7690m ???

John.

 

7690m = 6750m
7690m XT = 6770m

Same chip, same speeds.

 

Most likely your P6 voltage. You probably weren't stability testing correctly and unless you have a very special chip, 0.625 V is wayyyy too low of a voltage for 800 MHz. My voltage for 750 MHz is .750 V so for 800 MHz to be stable it should be about .7625-.7750 V. Your voltage for 2.5 GHz is fine (mine is at 1.1 V).


If you want you can underclock your P6 down to 500 MHz and the stable voltage can be as low as .7 V. That's my P6 state and my computer doesn't feel slow at all (usually starts feeling slow at 400 or 350 MHz)

Edit: Forgot to mention I have an A8-3530MX. Stable voltages could be different for each APU. Which one do you have?

When I apply those configurations to allow overclocking the nobs are stuck at "0" MHz for both core and memory and won't move at all. Before applying the EULA and unofficialoverclocking the nobs work normally, but clock limits are at stock.

 

I use Fusion Tweaker.

I have my P7 800mhz at 0.6875 , I have had two freezes over the last couple of days, but i have been messing with NB P0 and NB P1

I ran prime95 for 10mins on each frequency, is that long enough?

Do you find, that you can get a freeze when the notebook is idle, you come back to it after a few minutes to a garbled frozen screen.

John.

 

.6875 for 800 seem too low. If you are only testing using short duration, spend some time look at the clock in hwinfo , if the clock jump around or some core crash, still need to bump it up.

I would say just bump it up 2-3 notch, it is not gonna be noticeable in battery life. Better be safe than sorry.

 

Try reading my post above yours.

Is it just me or is everyone suddenly having low voltages for 800 MHz? It's like an epidemic of low voltage freezes!!

 

I just adjust the power slider in catalyst so only 800mhz is used and then run prime95 for an hour, even then my notebook is quite responsive, I browse the net with no slowdowns, is prime95 really using 100% of your cpu?

John.

 

I've seen this issue with 2 laptops, an Acer, and my current hp dv7-6165us. It seemed to be related to the stock drivers, and went away just as soon as I updated to 12.3. Try that and update us on if it goes away!

 

Neither 12.3 or 12.4 detect my dedicated gpu , only 12.2 preview does as it seems to have more drivers and is larger than the normal downloads.

John.

 

What do you mean when you say it doesn't detect your 6750m?

 

EDI : I have just installed 12.4 over stock 8.9 and it seems to have worked

John.

I don't get an catalyst control panel with 12.3 or 12.4 , also i have an 6520G + 7690M

John.

 

guys,I just started my first OC/UV tweaking on my dv6z A6. pls help T_T

P0:2000 MHz @ 0.9375 = laptop BSOD
so I increased the voltage twice as said in this guide to 0.9625 and started 2nd torture test
but HWiNFO64 shows my core 3 stoped while others are still on "self test"
does this indicate an instability?whats my next move on this one?did I do something wrong?

ps:I started Undervolting form stock settings.

 

yes, push the vid higher. my 2.0Ghz is 1.0125.
Typically you go from high to low so you dun get BSOD as much. core stopping is sign of instability.

 

so do i need to up voltage twice again to 0.9875?and what do you mean by -push the " vid" higher- ?

what and/or where should I look for other signs of instability besides temp and core status?how would i know if a core s throttling? all the k10stat,HWinfo64,HWmonitor has alot stuff in it,im not even sure if im looking at the right spot or what are all the things i should be watching for.

 

yes , up the voltage.

Typically it wont throttle under pure CPU stress.

Obvious sign of instability:
BSOD
1 of the core/worker went off (as in error)
not so obvious :
the clock reading fluctuate back to previous pstate often

Here is I typically do mine.

find a "guide" look up the value (clock/Ghz) increase the "guide" value around 3 notch voltage. run stress test (prime95 in the guide, do small or large fft either should be fine) , decease the voltage by 1 or 2 notch at a time and see if there is any instability.

If testing from high voltage to low and hit a BSOD, I would typically set the voltage 3-4 notch above the BSOD , that clock should be stable.

Don't stress too much on the ultimate lowest-clock. When you see other peoples example, expected a variance about +- .5VID.

 

Hi.

What is involved in removing the lcd back cover, to disconnect the hp logo light?

Is there only two screws, near the hinges under the plastic covers?

Thanks

John.

 

Will this help at all?
