*HP dv6z AMD Llano (6XXX series) Owners Lounge*

The CPU reached a maximum of 81 °C, I recommend to you to do first test with the prime95 software, since it stresses the CPU for as long as you want. I have to mention though that this is not my primary frequency (2.6 GHz), it's only used for emulators since they require more speed rather than processing power, hence the temperatures are normally a bit above of 70 °C but allows me to play NDS in this nice laptop 2.3 Ghz is a nice frequency to have and doesn't generate to much head under full load (a bit above of 70 °C)

 

thx musho, working perfectly! the temps are now a little higher, about 79°C, but still okay.

 

Musho can I get a 720/900. I would really appreciate it

 

I was having the same problem but solved it by going into the device manager and unistalling the drivers for both cards from there. Restart, then install the ones you want to try, restart again, and then run the tests.

New high score. Only a bit away from what seer had predicted... 2240!!!

 

Sure, here it is: F20 720-900.zip

This was the last one for today though. Time for me to catch some sleep. Night night, guys!

 

yeah that is not mine either I was just curious to see if you had similar temps as I wiht same v. I keep mine at stock but undervolted while on battery and a8 most of the time and for gamming but 2.2 po and 2.8 b0 for cpu intensive operations.

 

Good Night guy, thanks a lot!

 

Okay so I am intregued by the bios modding he he. So I have a few question but prolly no one has an answer yet...
1) can the igpu be undervolted and left at stock speeds?
2) how far can you push the igpu safely?
3) @ Musho how hard is it to mod a bios? because it may be easy if there was a way we could do it ourselfs and thus save you the trouble of making a custom bios or two for everyone that wants to try it out on the forum.

 

So I decided to really push this machine...

with cpu at p0 2.6 and b0 2.8 and the gpu oc to 750core and 975mem I get
p1913 in 3d11
g score 1931
p score 3235
c score 1139
Temps never exceeded 82c
I am using the 11.8 drivers with coolsense on performance and crossfire enabled

 

1) iGPU is not moddable/overclockable AFAIK. I already had a look at the vbios of that card.
2) See 1
3)

Not too hard. Althought it does require some experience with:
-Calculating and converting in Hex
-Hex editing the correct bytes
-Knowledge of how and where the clock speeds are stored in the vbios
-Fixing the checksum by changing filler bytes (00 bytes and FF bytes)

I've done it plenty of times now already though. Modding takes me 5 minutes per bios max. Not too much of a hassle, I enjoy doing it

 

How did you get 750/975 on the dGPU with 11.8? Did you mod the bios yourself? =]

 

1.- The efforts for changing the voltage of the 6750m so far hadn't been successful, but the frequencies can be changed almost at will as Musho has shown.

You can revert back even to the original bios from HP, I did that a couple of times.

2.- That depends mostly on your temps, but it's a rule that you don't want to exceed 90 degrees or you gonna fry something.

BTW, testing Crysis 1 with everything on max on my settings of 2.3 GHz at 1.0375v, 770 core 950 mem for the 6750m and the 11.8 drivers I get around 22 FPS with everything on max, even antialiasing and a resolution of 1366*768.

My temperatures are 88° for the processor and 85° for the 6750m, that's quite good for extreme gaming... because I really don't want max settings.

 

Okay I was mistaken about that. I did windows update and hp support assit updates and installed the latest ccc on amd so i just assumed I had the latest drivers. i looked my driver version and it is 8.861.1.400 so i am running 11.6.

 

He is referring to the speeds that you have, he hasn't made any bios with the speed of the memory set to 975, are you perhaps using the MSI afterburner?

 

I have been using msi afterburner

 

So I set my p0 to 3.0ghz with a v of 1.2625 jest for fun and ran cinbench.
I got 3469 single thread and 11856 multi thread with a temp of 90c. A little too hot for my likings but fun to test out.

 

I'm having a problem with this method. After uninstalling the drivers and restarting, windows attempts to install it's own drivers, which prevents the ones I want from installing. How did you get around this?

I notice in the graphics benchmarks it is stuttering or switching between the 2 gpus a lot and it is really affecting performance.

Upon checking msi afterburner, my GPUs are not performing as they should in crossfire.... and I reset them in the CCC. I may need to do more driver reinstalls.

 

It doesn't ask me to install the drivers when windows starts. The screen has a lower resolution but then I install the drivers I want and restart again.

 

Wow, drivers are officially borked with BFBC2. I've played with DX9, DX10, DX11 in various details and resolutions and locks up within 30-45 minutes. Temps are a cool 65-70C, and all CPU voltages were even bumped up a few notches. All I can say is they better make it work for Battlefield 3. I've really played as much BFBC2 as I can bear, but just playing to screw around with performance and monitor temps and such.

 

I have some questions before making the jump to Llano:

What's a good overclock for a A8-3500M (35W)?

Can the A8-3500M reach 2.4Ghz?

How would the A8-3500M @ 2.2Ghz overclock compare to a N970 2.2Ghz?

 

You try running it at stock clocks?

 

Well the bios didnt work, did the same thing that happens withh 11.8 for me when try to overclock the gpu. About a min after windows starts the screen gets all jumbled <--- technical term. Then it blue screens half a second after.

 

Mine doesn't ASK, it just starts installing automatically (like when you insert a usb drive for the first time). There is a way to disable automatic driver install, but it is not available on windows 7 home premium....

 

Yes, same result.

edit: Just confirmed again because wasn't sure if I disabled K10stat or just set it to one of the stock profiles. Disabled K10stat from Task Scheduler, rebooted, confirmed it wasn't running, played BFBC2 at all stock settings and sure enough, crash. I guess the good news is that it's not the overclock, it's most likely drivers, that hopefully will be fixed.

After you uninstall drivers, go into device manager, and right click each gpu and "uninstall". It will pop up on the first one you do with "do you want to completely remove drivers" (or something like that), check the box and then it will blow away any drivers it has. Reboot and it will try to install drivers but will fail because drivers were deleted.

---------------------------------------------

edit: Interesting find in the K53TA forums: http://forum.notebookreview.com/asus/608772-k53ta-bbr6-cooling-mods-5.html#post7895166 linked to here: http://forum.notebookreview.com/windows-os-software/599026-utility-access-allmost-all-hardware.html

A utility that allows for direct access to hardware registers. The one listed is for Asus. Wondering if there's a switch there for the HP. They are able to turn fans on max with that utility. Of course I don't want to brick my machine by doing so, and I'm sure Asus location will not be the same as HP. I wouldn't even know where to start though to verify.

 

problem!!!!!!!

in battery mode,
when i scroll a page, like facebook or others page forum, the brightness change,
the screen backlight i aasume is not stable.
anyone whit this problem?

i dont want send pc to repair after a week

 

Funny (well not really), I noticed this yesterday. If I switched tabs in Firefox, it would start dim then increase brightness slowly. And then noticed it would dim then get brighter randomly. Kind of irritating. Not sure if this can be fixed with a BIOS update or if it's an issue with the motherboard. I would see this with a CCFL if the inverter was bad, but not an LED light.

 

The automatic brightness changing is a default setting in the vision control center. Just go the the Power tab in the vision control center, PowerPlay, and then uncheck the box that says enable vari-bright.

 

If you're on battery you have to right click the desktop, go to graphics properties, go to powerplay and disable vari-bright. It's some battery saving "feature".

edit: Your BC2 problems might not be the drivers. BC2 for some reason has a lot of problems with online, just google Bad Company 2 crash and you'll see. I can't even join a multiplayer game for some reason.

 

I think hp has a host of environment sensing software, that controls fan speed, screen brightness etc. according to sensors. I did read it supposedly can tell whether you're on your lap or on a desktop and change things accordingly...
seer

One other thing, the 11.8 whql drivers appear to suck.

 

tnx a lot for solution

 

Ok, guys, been fighting with this for a few hours now after the bios update and I cannot get the 8.861 drivers to install, i can get the 8.81's which suck, and the 8.832's which suck... LOL

what am i missing here

seer

 

Thanks +1 on the vari-bright. It's not so "bright" if you ask me.

Regarding stability of BFBC2, I can play for hours on my desktop without crash. It's a nVidia GPU but not sure if that has anything to do with it.

Try going into device manager and uninstall the drivers manually by right clicking each GPU and select uninstall. Be sure to select "delete driver software for this device". It will only ask on one of them because same driver, but uninstall both. Reboot. Then run the 11.6 driver package, choose custom, and then select the video driver box.

 

Wow, the APUs are rather cheap to get @ebay. Could be a good option to replace my A6-APU, if crossfire will ever work better:

AMD A8-3500M APU with Radeon? HD 6620G AM3500DDX43GX | eBay

 

Or try to get an MX CPU if anyone can validate RAM that will work at 1600MHz and give a boost, along with Crossfire, theoretically should boost performance considerably.

 

Weird. I play BC2 every once in a while and I haven't gotten any crashes with 11.6, stock GPU clocks and my CPU overclocked.

 

Well sometimes I can play for 30, 40, even 45 minutes or so and no issue. Then all of a sudden it locks up. Heck with my new cooler it's been running 63C! and still locks up, so I know it's not temperature related.

------------------------

On another note, I have both the NotePal U2 and U3. With the 9-cell battery the angle sits kinda steep unless I let it sit in the slot at the top of the cooler, but then it sits too high up the cooler, and the U3 is a bit big for this laptop, but the three fans are nice.

 

I don't know, are you guys having any problems with musho's bios? Sent my lappie for a loop. thought I was going to have to do a rebuild, but managed to salvage boot, been replacing everything since...ONE thing that has come up that might interest you wingnut. Was in a hurry to replace the bios and went right past F20 to F18 and my idle temps fell on the floor. Must have some change they made to fan speed. in any event, as I type this both temps down to 34C. and last 3dmark11 run (thank god I got my linked crossfire working again, i.e. two plateaus without all the spikes) anyway, top temp in 3dmark11 according to afterburner was 67C. and that was only on a spike as the combined test began, then the fan kicked up and knocked it down to 62C. I'm about ready to lock this down and call it a day. Been trying to find what the improvement of F2 was over F18, seems there was an intervening F1D which "lessed fan noise"...heheh we all know what that means....anyway, I think I'll hold onto the F18 for a bit.

Seer

 

SO basically what you are saying is that the bios that originally came with the laptop makes it run cooler than the updated bios?

 

@seeratlas - Where'd you find F18 BIOS? Only one I see on HP's site is F1D and F20. It would be good to see the full BIOS update change log though.

I haven't had any issues with Musho's BIOS though and it's nice to have GPU set where I want it so it doesn't matter which drivers I use. Although I'd be happy to give F18 a shot.

 

That worked but now I have another problem. I wiped out the drivers completely, but AMD CCC installer refuses to have a "display driver" check box and refuses to install the drivers.

So unless I can get windows to detect the drivers somewhere in the folder, I have no display drivers!

 

Which drivers are you trying to install?

 

Wing, I just finished a cinebench11.5 cpu run and got a 3.33 that's highest on this box. and i was running afterburner in the background with everything else i normally run , norton, malwarebytes, etc. and the highest temp reached was 81C twice, but got knocked back down into the 70's both time. That's good enough for me. 3.33 is a pretty decent cpu score on that bench. Now, guess where I found F1.8. It was in my machine. When I got it to wake up after I thought it had gotten bricked, I raced into the hp bios utility, and hit roll back, and there it was. Have never seen it anywhere else. I *suppose* i should fool around with it so far not a hiccup and man its wild to look over and see that 34C in the tray where I used to see 40 to 44... I also had relatively mild cpu settings when I ran cinebench (well mild for me) I was expecting a 3.09 to 3.11 or so, then I noticed the squares were really boogieing around the picture. jeez, temp just hit 33C as I'm typing this. I'm on the coolmaster U2, but that's waaaaay lower than anything i've seen on this box. Oh, yeah, forgot to mention, the cpu on these settings with this bios just threw up a 3598 physix score in a trash run thru 3d11.

Seer

 

Can you post the BIOS file?

Of course now I'm seeing 29-30C at idle WITHOUT the cooler with my mod. I'm hoping someone will be a guinea pig and try the R&W utility to see if it will crank the fan up to max speed by changing the register of the embedded controller. If I hadn't modded my machine I would since I'm still in my return period, and just return it if it bricked.

 

here you go wing, look down in the lower right corner..

edit: Duh, it just hit 32C. as I was posting this.

edit 2: ok, now this is getting silly, just hit 31.

 

Does the fan sound any louder, like its running faster? Can you post your F18 BIOS file?

 

ok here's 31. if it goes any lower I'm going to put on a coat. LOL

oh room temp is 74-75F.
seer

re: fan, I don't hear it above the Coolmaster fans, I feel cool air coming out of the grill tho.
ok, I pulled the plug on the coolmaster fans, and I *think* i hear a faint whisper of fan noise. Certainly not blowing hard.
I'll see if I can find where HP was hiding that bios file for the rollback, any ideas of where to look? You might check yours, probably got it in there somewhere too.

 

Ok I got the display drivers working. The large 100+mb package that HP includes had the display driver as an install option, however 11.6a and 11.8 did not.

I still have crossfire spiking problems (((((((((((((((. failure.

 

Mac, i tried everything I could think of but could NOT get 8861 driver to install..

seer

Swat, worse than that, this laptop came with F20. I never new F1.8 existed till the crash and when i hit rollback, it rolled back to f1.8. Where it came from I don't know. Trying to find it on the computer now.

seer

this is the one that killed the spikes for me.

AMD VISION Engine Control Center Version 2011.0524.2352.41027 its an oldie i think.

seer

 

No I meant your actual BIOS file (.bin), not screen dump of temps or anything. Will probably have to put it in a zip in order to post it anywhere like mediafire.

 

Guys.... I need help.

For some reason when I tried to do a backup of my hard drive with Acronis Home, when the computer restarted and loaded a CD with acronis in it, it froze and I shut it down.

When I turned it on the caps lock led began to blink, I was scared at first but after some search I found that the BIOS went corrupt somehow because the capslock blinks two times, then stops, then another two times.

I'm trying to restore the BIOS but I don't know which filename is searching for this laptop.

My laptop is a DV6-6110sg and the motherboard is a 358D. Can somebody point me to a post where I can find the correct filename?

Thank you very much in advance.
