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

It doesn't help that the heat sink is shared and very thin on top of that. The heat sink you showed in the pics does not look very robust. they could have used an extra few pipes coming off the sinks to the fins.

If I buy one of these laptops I'll be getting those adhesive copper squares to stick along the pipes as well.

 

I have been able to overclock my dgpu without disabling ulps in system registry. So I disabled it and the only effect it had on my machine was my batter performance was cut in half.

 

You can overclock without disabling ULPS you just have to be using 11.6 drivers and "prime" MSI Afterburner with a 3D app, like setting GPU-z to "high performance" before starting MSI Afterburner. Disabling ULPS just eliminates that step of "priming" MSI Afterburner for overclock.

 

Actually the CPU has two heat pipes, one to a dedicated heat exchanger and the other one shared with the GPU but is much larger. I don't think just adding those adhesive copper square heatsinks will help. There is literally no air movement in that compartment as it's isolated from the fan. I plan on cutting some slots in the fan shroud that's isolating it from the CPU and GPU so it can get some airflow over the CPU and GPU, and with added copper heatsinks should help dissipate heat. But it still has to go somewhere.

I hacked open the bottom of the panel above the CPU and GPU and just doing that dropped temps 5-7C. I ordered some heatsinks that should be here in a couple days, but am about ready to modify the fan shroud as noted above and see how that fares. Heatsinks should only help. there really is very little room though between the heatsink on the CPU and GPU to the bottom panel, so you'll need some that are only a few mm thick. I'll be dremmeling to fit for sure.

Problem is I think I'll have to sand off that black paint (what the hell did they do that for?) to get good conduction between the heatpipe/heatsink and the square adhesive copper ones I add. That black paint serves no purpose that I can see except maybe to hide the inside component through the already TINY airflow slots that are UNDER the laptop that you won't see anyhow. But I digress.

 

Gratz and those are some great scores

Mac does that thing run in gl? is there a patch to get it to go dx10 or 11?

seer

 

you taking photos of this stuff Wing? I'm sure we'll all want to see what you're doing. Especially where a dremel might hit something 'bad' LOL.
Seer

 

It uses open GL yeah, and there is 1 mod I could try, but it is essentially a DX9 game, like alot of other titles I own (fallout 3, ect).

IDK why it wont work with the 6750...

 

My question is, is it really worth it to overclock the cpu. Even abbadon said there isnt very much gained from it. I think maybe the gpu would have more of an effect on over all performance.

 

Completely off topic but you guys have no idea how glad I am to be able to post here today. Yesterday early evening I took a full shot direct to the forehead from the bucket on a backhoe, on a construction tractor. Never saw it, and it was coming FAST. They tell me I did a back flip and flew through the air. Just so you know, I'm 6'4 and about 240, soooo to launch me...I got hit HARD!!!
I wokeup with my face about an inch from somebody's rear truck tire some 12 to 15 feet from where i was standing, wondering how in hell I was doing there, and how I got there. I have no memory of seeing it coming or of getting hit..just one moment standing there looking at the hole and the next laying there looking at the tread on a tire. Needless to say I spent the night on my back with my head packed in ice and tho I'm having some trouble moving, and have one HELLUVA headache, at least everything seems to be working, so once again, I'm reminded that life can be very short. Do what you enjoy, deal with the worst and hope for the best, and may you all be as lucky as me That bucket had six inch teeth on it, and I'm told if it hadn't hit me exactly the way it hit me, and Where it hit me (hardest part of my skull) it would have literally torn my head off, which would've left me no place to put my hats So anyway, if I repeat myself or forget something in the next few weeks, you might cut me some slack . I wish you all well.

Seems to me I read an amd whitesheet on the llano somewhere that had a footnote to the effect that th gl will always default to the onboard apu. I'm a bit fuzzy at the moment, but I believe if you can get it to run dx9, you can assign it to the 6750.

seer

 

Damn dude, that is incredible! Glad to hear you only have a few bumps and bruises Who else is gonna tell us how great our overclocks are

@ Varucell It depends how CPU intensive the task is you are doing. I have found it to be a pretty big boost to just overclock the p-states so it hits higher clocks more often. eg my 3530mx regularly sits at 2.4ghz and turbos to 2.6, very often (lower voltage) as opposed to sitting at 1.9ghz and boosting to 2.6 very rarely.

 

I would say it depends on the app. If its cpu intensive, there's a big difference in clocking the cpu. If its a heavily dx10 or dx11 game, then not so much. You have to remember that if you're using a lot of cpu, then you're restricting how much the igpu can contribute, and vice versa.

Seer

 

Guys, i'm pretty sure that GTA4 is DX9 *only*, i haven't heard about any GTA that runs on OpenGL.
That, or i misunderstood your questions about the game lol

@seer: it's nice that you are still with us, i've learnt a lot with your posts and as far as i can see, i'm sure that you're a great men also

 

Well I'm ready to take the plunge and undervolt this sucker, any recommended guides for a tech-savy/ overclocking-noob like me? And any monitoring tools I should use?

@seer Don't stress your head, let it rest. Head injuries are always bad.

 

That's exactly what the black paint is for, just to hide the copper from anyone looking inside through the vents. It was like that on my M17x R1 and R2 as well. Really unnecessary for them to do that as I doubt people spend time admiring the underside of a laptop. It is a very good idea to remove it, Isopropyl alcohol could probably remove that easy and maybe more cleanly.

 

Seer - Glad to hear you're alive and well. That's very scary. Take it easy and rest!

I did part of my little cooling mod experiment. Well let's just say it's partially a success. Where before I was hitting 90C (again) on Bad Company 2 at 2.4GHz (sounds like I'm not the only one), I hacked out a hole where the vents were for the CPU and GPU. That improved things about 5C right there.

Then I cut a slot in the fan shroud to let some air flow through the CPU and GPU compartment. That seems to help also, dropping temps down to 80-81C. HOWEVER! There's a HUGE BUT here (there's always a huge but isn't there?) the palmrest gets very hot. Plus the GPU tended to run a little hotter. I guess it's moving the hot air from the fan and heat exchanger area to the main compartment of the laptop. While airflow helps with cooling, it's pushing hot air, and obviously not good since it's right below the left palmrest.

I guess the compromise is a hotter CPU but cool palmrest as opposed to cooler CPU but hot palmrest.

When I get my copper sinks I'll let you know how that helps. But I'm thinking I'm going to have to electrical tape up the fan shroud because it gets pretty toasty when playing games.

The bottom enclosure and heatsink/fan assembly if I want to replace them cost about $125 total for both of them, so worse case, I replace both with new and out only $125 if I want to get back to stock.

 

I just tried the 11.6a drivers and i got this results:
AMD Radeon HD 6620G video card benchmark result - AMD A8-3500M APU with Radeon(tm) HD Graphics,Hewlett-Packard 358D score: P1711 3DMarks

Lower!

I'm going to do a few more tests, if i still get lower results i will go back to 11.8 and use the bios mod to overclock the gpu

 

Rest your head seer, its good to still have you here.

 

Good to hear you're alright seer. Did you have yourself checked before going home? sometimes you feel ok but there are underlying problems especially if your were hit that hard. If you have the time get an advice from a medical practitioner. Usually they would have you tested (Skull series, MRI, ect) just to be safe.

As to heat of the laptop, I hit my highest yet. 84C @ 2.4 playing duke nukem for sometime. I usually play Heroes of Newerth at 1080p with high settings and highest I could get is 81C.

 

Hope you recover just fine, hate to lose any of that knowledge you have been imparting on these fourms.

 

What I did last night:
Use fusion tweaker to set all p-states to 800MHz. Test with Intel Burn for stability. Once I find a stable voltage, leave P7 as it is, and set P0-P6 at 1000MHz, and so on. That way you can ensure that the lower P-states are also stable under load with the undervolt. I used Core Temp to ensure that the correct P-states are being achieved.

Once you've got your voltages decided, follow the K10stat guide and make the settings permanent.

Aspire Gemstone: K10STAT AMD Griffin Processor UnderVolting Guide

My stable voltages are:
800 MHz - 0.7V
1000 - 0.7325
1200 - 0.7750V
1400 - 0.8125v
1600 - 0.8500V
1800 - 0.9125V
2000 - 0.9750v
2600 - 1.125v

I have a 3510MX.

Good luck!

Seer, great to hear you're okay!

 

Seer,

Glad, you are doing well!

ikrana,

why are you using FusionTweaker and later on, you switch to K10Stat, to make the settings permanent? FusionTweaker is supposed to do that too, if you activate the service. Is it not working?

-witteks

 

thx, man! rep+1
Now the next bios thing I'm looking for, would be the modded one with the "Ctrl-b"-option to get into the ram-timings menu. Then I'd consider upgrading to 1600-DDR3.

Oh and of course, I'm still waiting for a breakthrough on the overclocking-bios front.

Any news on that Musho?
I remember the guy from RadeonBiosEditor edited a few unsed bytes in his first bioses, just to correct the otherwise wrong checksum. Maybe you could find a few unused bytes and edit them too...

 

It is definitely worth it to a certain extent, especially if you have anything other that the A8-35xxMX APU's, but once you get to 2.2GHz or so the difference in game just doesn't justify the difference in heat production, at least for me. If 2-4 FPS is worth another 5-8C to you then that is your choice.

 

I tried activating the service. Doesn't seem to work for me. I have to set it up every time I reboot the machine

 

Did you tried as described on the Wiki?
Click on "Service.." , click on "Update" (current settings should show up) and than hit "Apply".
I'm just curious. If there is an exception or the seetings look odd, I could try to fix it. Screenshots also help, if you want to use the program.

-witteks

 

Yeah, 2.2GHz seems to be the sweet spot for me too. It still runs hotter than I'd like or expect it to, but it's decent.

 

Just so you guys know, now after 15 minutes of Prime95 large FFT's with a repaste and cutting out the bottom panel above the CPU and GPU, my temps run 70C at 2.2GHz in a 25C room! My heatsinks should be here by Friday, see how much of a difference that makes. Running mine at 2.2GHz at 1.050V, actually ran fine at 1.0375, but got errors after about 20 minutes prime95 running 1.025V so bumped it up a bit to be safe.

The biggest frustration out of all this is still the fan though. If we could just crank it up to full on demand, it would help things immensely. I wish I knew the best person to contact at HP to make the request. Actually my temps go between 70-73C because once it gets to 73C the fan picks up a bit and drops it down to 70C, then the fan drops speed and temps rise again. Cycles over and over again.

 

I just tested the musho's mod (I integrated it with the whitelisted bios) and look the results:

Spoiler

Works like a charm! Thanks musho!
I'm going to set it to 800/900, i had that config on the 11.6 driver and worked great.

 

So how's the whitelisted BIOS working for you then? No lockups? Can you edit the bios settings? I heard this can cause black screens.

 

Works fine, after flashed i changed the bios language, enabled SVM, disabled fn by default and changed boot order. I'm not bricked

I had a " bios recovery pendrive" ready, just in case

 

Are you using the one here?
http://forum.notebookreview.com/hp-...n-whitelist-hp-authorized-wireless-cards.html

Or how did you whitelist? I really want to get an Intel 6230 in mine but don't want to brick my machine in doing so.

 

Is there an absolute minimum voltage for under-clocking?
Cause I can go under 0.7v and it still passes the Intelburn test.

Also with the wifi cards can't you only use the Intel cards in laptops that have Intel processors?

And anyone try the 2x2 broadcom 4313AGN card ?

 

No, Intel cards can be used in any laptop.

 

I'm using this one: kr105_sp54025_NWL_ByCamiloml.exe
My mobo is the version 358D.

I'm now running at 800/900, driver 11.8 and i got this results:
AMD Radeon HD 6620G video card benchmark result - AMD A8-3500M APU with Radeon(tm) HD Graphics,Hewlett-Packard 358D score: P1915 3DMarks

I think that i need to tweak it just a little more

 

On my undervolt/max battery profile, i have P6 set to 100mhz and 0.6250v

 

Thanks, I may have to consider that, mainly for the whitelisting.

At 100MHz doesn't your system move at a crawl? I mean that's probably less than single core atom speed!

 

So it seems i have a big problem with direct x games detecting my 6750 which is why gta4 would not work. When i am in fallout new vegas launcher, it only lists the 6620g as my availalbe gfx adapters. Has same issue as gta4, and fable 3 where there is no video but audio.

 

Are you running in crossfire? If not maybe it would detect both GPUs with it on, don't know.

 

Man this is sucking more and more. Bad Company 2 is locking up after 15-20 minutes of gameplay. The sound stutters for a while, the screen is locked up and then the sound eventually goes away and it either goes black screen or just sits there. I have to hard shut down and reboot.

I've tested every P-state profile for 20 minutes prime95 stable. Strange thing is if I fix all P-states to the same, the game runs stable.

I've tried 11.6, 11.8 pre-release, 11.8 WHQL drivers, pass IntelBurnTest with flying colors. I don't get it.

 

Try to bump up the voltage for each PState by one step and try to play again. Might be the case that your stress testing was not heating up the die enough in slower PStates. While gaming, your die is hot and gets into a slower PState eventually, which makes the voltage not beeing sufficient for the frequency/temperature combination.

Edit: You might just need to bump up the slower PStates a bit, if the theory holds.

Hope that helps,
-witteks

 

I did bump up each P-state voltage one notch, and I tested with Prime95 and MSI Afterburner running in the background so it was sufficiently hot. It's unfortunate that it takes so long to see if it crashes though, because going through each P-state will take forever to get it stable. And hate to run all P-states at higher voltages than they really need to be for heat and battery life. I may just use a profile with CPU fixed at 2.2GHz on all P-states when gaming.

I just bumped up P-state voltages another notch and will see what happens.

 

It's a sign that you should have kept the K53TA.

 

Yeah I'm thinking that more and more.

It wasn't quite as a good performer but it ran cool and didn't lock up, well at least what I used it for. I'm going to do a clean install and see if that helps matters. I've fudged around so much with drivers and everything else there might be some issues going on there too.

I just ran with my voltages bumped up two notches and still it locked up after about 15 minutes. GPU was 77C, CPU was 81C.

 

HT, I had to bump up my voltages one notch from what intelburn would pass as stable to get 3dmark11 to finish. Then after I oc'd my dgpu with after burner I had to bump up 2 more notches to get 3dmark11 to run the physics test without locking up, and my temps @ 2.2 were hitting 74-77C with the dgpu at 660 core 880 mem. Those values passed and I got a score of P1920, but it locked up after about 45mins of Section 8 single player and my temps were 84-85C. I haven't had time to mess with it since then.

 

I think I will just use a profile for general use, and one for gaming, just fix it at 2.2 across all P-states and leave it. So far it's been stable, but more testing will confirm. Only thing I can think of is at higher temps if it jumps down to a lower P-state it's unstable, and no real easy way to test for that.

Although when CPU and GPU are highly taxed, crossfire is off, and even if I fix the speed to 100% (in advanced power options) the speeds still bounce around at higher temps.

 

For you guys running xfire/dual graphics, when things start to go south, there's a cure that almost always works...bring up CCC and hit 'reset to default' LOL. Apparently those default settings really are the best, and at least you now have a chance to go into a different direction.

seer

 

Ok, here's a new one. when you start up the HWinfo program, either 32 or 64, you will note near the center of the 'System Summary" page, a red "CTB". which if you hover your cursor over, a message will pop up saying "AMD core performance boost support". now, that new program 'Fusion Tweaker" has some interesting options...and *apparently* it is possible to turn off that 'CTB" with Fusion's ability to reset B0 (the boost setting) to act like "PO" the dominant system favored p state. If you do that, the calculating ability of the cpu jumps a BUNCH, especially if you also check the 'Fast Up' box in Fusion Tweaker, which causes the cpu to ascend from the lowest p state, and jump straight to the highest P state on demand, do not pass go, do not collect 200.00 and do not bother to stop at any of the other pstates on the way up. Together I think those two things accounted for the 3600 3dmark11 physics score I can get. If you run cinebench 11.5 on cpu multi, you'll see the squares flying round the graphic with always one square easily finishing before the others and moving on and most likely a .10 or 15 increase in your cinebench score. Mine went from 2.86 or so to 3.16.

you will of course, get some more heat but not as much as if you just peg the cpu to a high fixxed number.
Oh, and for comparison?
Asus K53E Core i5 2520 at 2.5mghz can do 2.8. heheh. The i7's can do 5 something, but then they're using 8 threads, not 4.

I may have to play with that seeratlas, may circumvent my lockups after an extended period. Because if I lock all P-states at 2.2GHz things run fine, but set up a profile tested tried and true with Prime95, combo Prime95+Kombustor, and also IntelBurnTest without error, yet after 15-30 minutes in Bad Company 2 lockup. I had an inkling it was related to voltages, but bumping up each P-state one by one would be too tedious to test.

In this case it would just bypass all other P-states maybe eliminate the issue.

On another note, I ordered a Notepal U2 cooling stand from Amazon for my beloved DV6z that hates me. Well someone in the sky is laughing at me because the box was all mangled, as was the product packaging and the stand itself. I mean how do you deform something as solid as this stand without punching it with something mechanical and large.

I actually have a chance to go play some games with a friend tomorrow night and am irritated that my system might lock up on me or whatever... grr...
