The Definitive DV6z Llano Overclock and Optimization Guide

guys... if i select in the catalyst and windows, to allways run at CPU at 100% regardless of battery or AC, the only thing that matters in regards of OC would be changing P0 and B0 frequencies and voltages right ?

the p1,p2,p3,p4,p5,p6 would'nt matter cause i would always be running at 100% correct ?
thanks

 

You would have to turn off cool n quiet if you want to run at 100%. Or just go into windows power settings and set min and max CPU speed to 100%.

 

Anyone? If I am asking a dummy question, please, let me know too!!

 

samgu, it seems a great frequency for such low voltage... but hey, as the pro's say: "every cpu is different"

maybe you got extremely lucky, or perhaps you're doing something wrong..


@ HT i don't think i have this cool n quiet stuff.. at least i've never seen it.. and i didn't install the HP support whatever, maybe that's why..(if not, where can i find this cool n quiet?)

And yes, my CPU is minimum and maximum at 1.4GHz in power settings


Thank you for your help

 

Thank you for your answer! I followed the tutorial twice, word by word, and I think I might have been lucky then!! I will try to lower my voltage a little bit more to see if I get a lockup or something like that. Should I apply the setting and try to play a game for example, or just keep Prime95 running is good enough?

 

yeap, keep lowering till you get a lockup or bsod, when you do, pop up to levels of voltage and leave prime95 running for a good few hours just to make sure you found the perfect set of frequency x voltage

that's what i would do..

 

Thanks, highly appreciated. I know I may be doing something wrong because it's too good to be true to achieve 2,2ghz with 0.7 volts, but I really followed the tutorial. The laptop was working flawlessly for almost 45 minutes and then I decided to stop the tests and return to the default settings!! I will perform new tests and will post the results in here. I also checked on CPUZ and the numbers didi change reflecting voltage and speed, so let's see how lower I can get!!!

 

Something has to be wrong! I got 2,2Mhz with 0.450 volt!!! Is it possible that the programs are showing something but hardware is using a different voltage value?

I attached a picture of all progrmas up and running.

System has been running with this specs for 27 minutes now.

 

run on battery for a sec and see how much it draw Oo? Maybe a ultra lucky chip .

 

Run HWInfo64 while running that because I find it more accurate with voltages. That seems like an error or an anomaly. That seems to break all laws of physics.

 

I will try that when I get home. Didn't think about before.

I am running with HWInfo64. It's the rightest windows in the picture, and it matches with CPUZ. Weird!!!!!

The Max voltage that I can select is 1.275 and the Min is 0.450. But this chip is for sure "strange" because when I select 2,8ghz with 1.275 volt it freezes. The max I can select is 2,6ghz.

 

I have questions about overclocking my 6750m. I followed the guide and managed to raise the core clock and memory clock to their max values (780/1040) (WITH THE OTHER VALUE AT STOCK) without seeing anything weird in kombustor or crashing. What are these artifacts supposed to look like?

And when I set BOTH values at 780/1040 and run kombustor I do crash. Is this supposed to happen?

Where is this Musho's Bios?

 

What do you mean by set BOTH values at 780/1040?

Musho's BIOS: http://forum.notebookreview.com/hp-...-llano-overclock-optimization-guide.html#bios

 

Core clock: 780 MHz and Memory Clock 1040 Mhz. The respective clocks for the core and memory that were tested STABLE for me when testing each one overclocked by itself.

 

you test it together, not by individual. Up core first then mem.

 

Oh I understand what you meant to say now. Yeah, just because they run independently doesn't mean they will work together, but it's a good gauge of how fast it will run. I have to step back my clocks a bit when run together too.

 

hey guys, quick question.. is it a problem if i select all cores to only run at 2ghz ?

i mean, no B0 or P1 P2 P3 P4 P5 P6... it only runs on P0 which is 2hz

that's ok right ? i only user A/C adapter and the temp is good

 

hey guys, there's something wrong here, its not possible..

look at my config :



im running STOCK clocks.. here's two things :

all 4 cores are on 2.3ghz aparently

is that normal ?

and regarding my GPU, my clock is 100mhz and memory 40.5
according to the hwinfo i have to multiply my clock by 8 and my memory by 16, so it equals to :

core 800mhz
memory 650mhz
thats stock right ?

so i think gpu is ok, but my processor seems to be all 4 cores on turbo eventhough im running stock clocks

am i reading anything wrong ?

thanks!

 

So I increase the memory clock WHILE the core clock is at its maximum stable? I thought the guide meant to test them each INDIVIDUALLY before testing them TOGETHER

So if the purpose of this is to have both core and memory clocks at high, stable clocks what's the purpose of the guide saying to test them individually if they will have different stable clocks when testing individually and testing together?

Confused Face.jpg

 

human, typing error and brain freeze does happen

 

No you should test them individually, and then together. But that's only so you know what your limits are. It doesn't mean that you can run both at whatever maximum is individually.

 

but usually core OC have a better performance boost so try to get higher core then mem

 

..Does anyone else's dv-6135 make an occasional beeping sound after undervolting? And does anyone know what the cause might be, if so?

 

I some other issues:

I just discovered that afterburner can have its clock limits raised after you set a higher clock configuration than stock and restart afterburner. So initially I can set the clocks up to 780 core/1040 memory, but when i leave it at those clocks and restart afterburner they can now go as high as 1015 core/1355 memory. Is this a normal phenomenon with afterburner? Can the clocks above 780/1040 (i have a stable core clock of 800) be set when i startup windows? And is there a way around this when testing overclocks?

A second problem: Sometimes when I'm testing overclocks kombustor fails to display the fuzzy "msi" screen when testing the 6750m (discrete graphics(. I already set the kombustor (directx11) to "high performance" in catalyst (I'm using version 12.1). This happens when I use any of the D3D options, and when I use either GL options it uses 6620G (integrated graphics). I believe this usually happens right after I test an overclock so the 6750m may be "resting" and it requires me to restart, but sometimes it just happens when I haven't even tested it yet. Anyone know this problem and have a solution besides restarting?

Edit: To clarify, it basically sometimes just shows a black screen. Happens only with any of the D3D modes. When I choose either GL modes, it works, but only uses the integrated graphics and not the discrete one.

 

It's just a glitch with MSI Afterburner. You can also change it by moving slider all the way to right, going to settings, selecting the 6620g/6520g GPU, click OK, wait a second or two. Click settings again, choose 6750m again, then click ok, now it will allow you clock further. Afterburner is a big buggy with little things like that.

Not sure.

 

New owner, simple question, how can i turn off the hp logo on the back of the display off.

It seems to show though the lcd screen during boot and other dark screens

A thousand more questions to come

Thanks for any help

John.

 

You have to remove the LCD bezel and unplug the cable.

 

Wow what hp model do you have? I have a dv7 with the light-up logo and it doesn't show through the display.

 

It was a really common problem, you only notice when your lcd is off with backlight on . (when booting probably)

When the LCD is w/ graphic , it is unnoticeable.

The lights on Dv6 are all annoying for me except the wifi/cap lock ~~

 

Here`s a strange one.

I am creating my recovery dvd`s , 5 dvd`s , it creates dvd 1 and 2 fine and then asks for dvd 3 but does not anything.

I have tried a number of blank dvd`s both dvd-r and dvd+r , and it still doing nothing.

Now i have burn recovery dvd`s on a lot of notebooks, so i am not a newbie at this.

I have tried re-booting the notebook to no avail.

Thanks for any help.

John.

 

hey guys i have a8 3510mx and i tried to overclock but i got blue screen, i was wondering could someone post a k10stat stable overclocking profile....thnx

 

Someone else's stable profile will not work for another machine. Every machine is different, so you really have to tune for your specific machine.

 

You can use my profiles, so far it worked stable on all E2, A4, A6, A8 Llano laptop that I tested:

1.15 2.4GHz
1.025 2.0GHz
0.9625 1.8GHz
0.9125 1.6GHz
0.8625 1.4GHz
0.8125 1.2GHz
0.7750 1GHz
0.7250 0.8GHz

These voltages probably can go down with 1-3 steps, but won't make difference, so recommend keep these to not get again BSOD.

I also recommend to use FusionTweaker instead of K10Stat, because easier to make custom P-state settings permanent.

 

oh thought i could use someone else's profile, i see that some ppl overclocked a8 to 2.8 GHz wanned to do the same thing .....thnx anyway for your support.....

 

You can try it, but use it more as a guide to start with, so don't be surprised if your system locks up.

 

Have you experienced this problem? Has Kombustor show nothing but a black screen?

 

This is not quite true. I could manage my 6620G from 444MHz to 457MHz!!! I know it is not much, but all the little matters. Maybe with a more recent version of MSI Afterburner can overclock better.

 

I did a system restore, but recovery is still asking for my third dvd but there is an dvd in the drive, windows recognizes it, and i have tried a few blank dvd`s

I have read there is a hack to allow you to write more than one backup, does anybody know what it is, maybe it will fix this fault.

Thank

John

 

< 3% won't make any measurable difference. also fire up HWInfo64 as I find that to be most accurate measuring GPU speeds. And only real way to tell is to do a sensitive benchmark to measure the difference, even then it will probably fall in close to margin of error.

 

No, no, it is like each extra MHz makes one extra 3DMark11 points. If I could manage up the 6620G to 600MHz, I could hit 1000 points and do not need to buy Trinity...
The importance of this discovery is the integrated graphics can be overclocked, just no programs to support it...
Here is the HWInfo64 screenshot, which also verifying the overclocked result:

 

Thanks for that. I'll have to try later. I don't know that it's a software support issue but most likely hardware limits on the GPU itself. I would love more than anything to be able to overclock IGP, but I just don't think it's physically possible.

I'd say your best bet is to call HP and tell them your recovery process failed. Hopefully they will send you recovery DVD's.

 

Yes, try it definitely, might your 6620G will act different, plus you have more experience to overclock laptops. Use the beta Msi Afterburner, because the regular version do not allows to do anything.

 

Second run:
P894 3DMark11
17021 3DMark03

This mean overclocking 6620G by 13MHz, makes 23 extra 3DMark11 and 234 extra 3DMark 03 points. If we could find out how to overclock further, than Llano will kick the ess of Trinity for both CPU and GPU power .

 

I dunno...

From what all the review websites are saying it looks like the CPU will be 29% faster than Llano and GPU will be 56%.

Plus, it's not to say that Trinity won't be able to overclock as well. It may overclock better than Llano and scale better to boot.

AMD Trinity delivers 29% more productivity and 56% increase visuals over Llano

 

They compare the CPU speed with the stock clocks of Llano. However Llano can be overclocked more than 29%, while Trinity we do not know yet, but probably not. Trinity's base frequency will be very high, so there is only little room left for further increase. Believe me Trinity will disappoint people.
I would not eat poison for Trinity IGP as well, because based on Cayman. Cayman generates to much heat, while performance not as bright.

 

I don't really want to talk to HP at the moment while i decide whether i keep this notebook or not, I dont want to register any details with them.

Anyway i solved my problem, I have got into the habit of making a clone of the original hdd with Acronis before i even turn on a notebook for the first time, So all i did was a complete restore from my backup, and once i had windows running i copied the restore dvd`s to a flash drive.

Thanks

John.

 

help please guys

 

Yes they are normal. 2.3 GHz is the turbo mode and the 6750m is not being used so it's frequencies are low.

Where did you get the idea Trinity won't be that good?

 

but all 4 of them at 2.3ghz ? turbo isnt supposed to boost one at time ?

 

I thought the same thing as you, but with one correction, turbo turns of 2 of the 4 and boosts the remaining 2 to 2.3 (or whatever your turbo clock is). I've been seeing the same thing with HWinfo64 running.
