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

Just to make sure I'm not crazy (well completely at least), I went back to my Asus and realized in-game with Crossfire enabled both my GPU's are pegged at 100%. On the HP my dedicated GPU is running only 35-50%, and integrated bounces all over the place. Something is screwed up. I do realize the HP does perform better it's just that the Asus has rock steady framerates where the HP it bounces all over the place.

 

Are they running the same AMD drivers?

 

Exact same. Could it be the 6750m with GDDR5 is that much faster than that 6650m with GDDR3 and at 1280x720 the 6750m isn't being taxed as much? With the CPU as the bottleneck?

Sorry for all the questions but:
What speeds and temps are you running again abaddon?
Do you play Bad Company 2? How are your temps?
Can you control your fan?
What is your idle temp? Mine is 46-48, but on Asus it's 36, so I'm thinking some cooling issue (again).

 

I think there is a serious issue with the drivers. I cannot even run 3dmark vantage without it saying device removed error in the first graphics test. I am running at completely stock clocks so it has to be stable, yet the error is supposed to be an indication of instability.

If i turn crossfire off, 3dmark vantage just shows a black screen. MSI afterburner does not show gpu1 (6750) being used, but it shows gpu2(6620) and gpu3(?????) hitting 100% usage.

 

If it's not showing GPU1 that means ULPS is enabled. Either disable it or start an app (users here are using GPU-z) and set it to "high performance" before starting MSI Afterburner, then GPU1 will show up.

 

That is weird that it is enabled, because I disabled it in the registry already.

I checked the registry and it reset....... perhaps windows update did it???

 

If you ever update drivers then it will reset the ULPS. I think I'll make a reg file to quickly enable or disable ULPS.

 

I turned off ulps in the registry. however, gpuz states that it is enabled, and so does sapphire trixx.

GPUz also says that crossfire is disabled for the 6750, but it is enabled for the 6620 with 3 GPUs. Crossfire is enabled in AMD Vision.

EDIT : When i followed sapphire trixxs request do check the box and restart is re-enabled ulps in the registry -____-

OK this is just stupid. ULPS = disabled in registry, and when I checked with ULPS utility. But gpuz and sapphire say it is enabled when it clearly is not. I can OC my gpu fine..........

 

LOL. I was thinking that my DV6z was performing a little better. I had DV6z side by side with my Asus, didn't realize my Asus was on battery, plugged it in and a solid 45-50fps.

 

So the asus is performing better? or equal? That really makes no sense as the hp should be superior in both cpu and gpu.

 

It depends on the game. Since Bad Company 2 is CPU bound, then the GPU doesn't matter as much. My A6 runs at 2.2GHz at 70-72C where the A8 3510MX in my HP runs at 85C. I think there's some thermal throttling going on internally. I'm going to repaste my HP hopefully tomorrow and see if it helps. Otherwise I'm just going to keep the Asus and upgrade the screen and blu-ray. I like the construction of the HP overall though, and by the time I buy a screen and blu-ray that will add another $150-$180 to the price of the Asus, close to the HP.

I have both computers sitting next to each other, the HP is idling at 48C, the Asus at 36C. So something is odd.

 

What are your cool sense settings?

 

1. Right now I am running at 2.2GHz @1.025V with a turbo of 2.6 @1.1625V. When the CPU alone is taxed the temps range in the high-60s. When both the CPU and GPU are being stressed I get to the mid-70s.

2. Not often recently but the mid to high-70s is as high as I have seen it go at these settings. At 2.4GHz @1.075V it gets up to the low to mid-80s.

3. I honestly haven't tried. Like I said earlier, the difference in performance from 2.4GHz to 2.2GHz is almost nothing in games I play but I get temps 5-10C cooler so I keep it at 2.2GHz. With temps under 80C I haven't bothered to try to control the fan.

4. My idle temps are below 40C, usually around 36-38C in a 72-75F room. Your idle temp is the highest I have seen mine go with heavy flash browsing and multiple background tasks running in an 80F room.

 

Will it ever be posibble to overclock the gpu from 8.881. I really want to but 8.861, causes aall sorts of in game issues

 

I just tried FusionTweaker for OCing, looks a lot easier than K10Stat for Newbies:

fusiontweaker - Tool for undervolting/clocking Lynx (Llano) platform APU's - Google Project Hosting

 

Does anyone else's fan make a wierd sound like its hitting something? Especially noticeable around 60C. I feel a RMA coming.

 

I had no luck with OCing, still freezes...

 

I wonder if they changed something in the 8.881 that makes of so you can't oc

 

It's most likely possible to OC the GPU on the 8.881 drivers just fine with a modded bios, but nobody is willing to try out the bios I uploaded. If someone could try it and confirm whether the GPU runs at 610mhz/910mhz instead of 600/900 it would be great.

 

Musho, our stock gpu clocks here are 600/800. In fact until very recently I was unable to get my gpu to reliably run at anywhere near 910.
seer

 

7, that is a VERY interesting program. I'm going to do some playing around with that. thanks for the headsup.

seer

 

Huh? Are you sure? According to this site they are supposed to run 600/900 at stock...

Seer,
Here's the screenshot. The oddest thing is that the turning is responsive. It's the braking and accelerating that's laggy. I have no clue why. The game itself is butter smooth. F1 2010 does seem to be dx9. Should I try the newest drivers?

I can't seem to embed images, so here's a link.

well you might try some compressed air, might have a residual sliver of plastic from the chassis or tape or something got sucked in there. hold it so that gravity will work to the best effect and give it a few blasts and see if anything comes out

seer

 

Now THAT is a very interesting observation. You might consider running the kombustor benchmark several times changing only the power profile you use. I notice far less 'bouncing around' on "hp recommended" than on max performance.

seer

 

since you're going to repaste anyway, why don't you open em both up, switch the apu's and bolt em back together. Would be interesting how much each changes..

seer

 

Seer, are you positive stock clocks are 600/800mhz for the 6750? I've just examined some more modules inside the bios, and there are indeed 2 different 6750 modules in there. One with the stock speeds of 600/900 and one with the stock speeds of 600/800.

In my original mod I've modded the 600/900 bios, which won't do anything if the module doesn't actually get loaded, so I'll have to mod the other module to 610/810 to see if it changes anything.

Interesting enough the 600/800 is codenamed "HP/Flex Kelly/Young Whistler Pro" whereas the 600/900 is codenamed "HP/Flextronics Kelly 1.0 Whistler Pro". Seems like HP deliberately made an underclocked version of the 6750 with the "Young" prefix. (Whistler Pro vs Young Whistler Pro)

Anyone willing to try it out if I mod it? I don't really feel like modding it, if nobody wants to try it out. Atleast not until I get a Llano laptop myself. Note that if this works, it's going to work regardless of driver version, ULPS setting, etc

 

Btw Seer, about your new memory not running at their 1600mhz specification, if you're feeling adventurous you can flash the SPD to include the speeds you want them to run at by using this tool. Use at your own risk, advanced users only!

SPDTool: Read, Edit and Flash your Memory's SPD

 

I tried with performance. Coolest just clocks the CPU down. I have since done a clean install on an SSD and same results without coolsense installed.

Thanks. More I use this Asus and think about it, there's definitely something wrong, probably bad paste job. My Asus idles at 36C as well in a 75F room, right next to my HP, and Asus also runs max 75C at 2.2GHz.

 

Sorry if this has been answered, how do I get catalyst control center on my laptop? I removed the drivers and installed 11.8 but its still the "ATI VISION" center, I don't have the ability to effectively control which graphics card it uses or whatnot

The configuration options for this thing are shockingly bad, really regretting getting this laptop now as the performance isn't any better than the radeon 4570 in my old laptop

 

Hmmm, looks like it is cpu centric. the gpu's are loafing and the cpu has all four cores rocking.. are you running "ganged" or "Unganged" on k10stat?

seer

 

I've tried with a couple different power profiles with the same result. I will attempt a different driver installation route and see if it helps. At my moms for the day with my rugrats, so won't be able to mess around until tonight if I'm awake enough, otherwise tomorrow if I can keep the kids occupied with something for an extended period long enough to mess around.

Yeah, I would except I don't feel like disassembling and reassembling, or have time to, before next Tuesday when I have to make the decision whether to return the Asus or keep it. Both laptops basically require a full disassembly to get to the heatsink. Which is looking like an hour or more process for each.

My 6750m is 600/800.

 

thanks musho, I was aware of that but I thought i needed an eeprom burner to do that.. Looks like I have some reading to do.

And on the bios, that is VERY interesting. yeah go ahead and mod the 'Young" kid and I'll see what it does, once I bone up on insyde bios recovery LOL.

seer

 

someone just needs to make some stable custom drivers with a big 3 button GUI

- Use 6620 integrated
- Use 6750m discrete
- Use both in crossfire

lol its just that simple amd.

 

The cores are unganged, but don't seem to run unganged. I had overclocked the P0 state to 1900, which the CPU does seem to hit. Coretemp correctly reports 1900MHz, while System monitor still reads P0 as 1800.

Is 80C under load normal? I thought that was a bit hot.

 

seems like it would be doesn't it lOL. sounds like a big 'duh' to me too.

seer

 

well, as we learn and fine tune our systems, out temps have been coming down, except for Wing who seems to be dragging around some satanic residuals Ideally you would only approach 80 under extreme load conditions. in fact, see my next post.

I guess the name says it all

Lemme know if it works! Thanks!

Edit: Figured I should quote myself with the instructions, so here they are.

 

Thanks mush, i'll give that a go a bit later tonight, sorry no instant gratification but i made another breakthrough, kindof LOL.

seer

 

With your RAM?

 

Ok, did some thinking, changed a few settings, and i believe a new record 3dmark11 has been hung up on the wall Here's the screenie:

http://i726.photobucket.com/albums/ww267/seeratlas/2162a.png

Now couple of things to note, I actually LOWERED my clocks for this score, AND if you look in the lower right hand corner you'll see all the background stuff that was running! In fact, I wasn't trying for a record but just a quick run inbetween doing some surfing reading up on some white sheets, but when I saw the intial numbers on the first test, I let it run. I was online, had all the sensors up and monitoring, with all sorts of crap in the background..and I beat my previous base score by over 50 points.....and now, the dgpu clocks? 762/834 which is chickenchit compared to what you other guys are getting out of the 6750. Man if I only had your gpu's...imagine what a 920/1050 run would net.....sigh..
Anyway, the guys with the 'mucho power' sandybridge cpus and their overclocked 6770's over in the Dv6't' forums..are even deeper in the 3dmark11 dumpster hehehehe AND with the privilege of paying more money Man these 'z's will bring a smile to your face

edit: oh, those numbers in the bottom right are from top to bottom , fan speed, dgpu temp, igpu temp, and in the left hand column, those are percentage utilization numbers. Since i was already on the net, the test finished, i hit the see the score button and when it came up, hit the screen cap. Was a matter of a few seconds from finishing the test. Highest temps reached *appear* to have been between 68 and 72C as I heard the fan shift levels just at the end of the test, and that's where my custom fan profile kicks it up to 87percent. oh and I also had two external drives hanging off the usb ports...so, without all of that, probably a bit over a 2170 or better.

Seer

 

Yeah I am not sure if it is the latest bios or the fact I reinstalled my gfx drivers, but now in afterburner GPU 1 option is called "AMD Radeon 6600m series and 6700m series" as opposed to "6750m" .

Can anyone else confirm this.

@seer lol I do not think anyone has hit 920/1040 with a 6750 yet. I thought I had 830/1040 stable but I got a few artifacts popping up so time to revert to 800/1000.

 

Makes me sad I want to overclock. I am going to see what I can get going to for 11.6 drivers

 

LOL, darn it, i remembered someone and it turns out to be undeadrat who put up a 2159 which is what i remembered... however, went back and looked at his post and darn if he didn't rerun it with some more clock and put up a 2162 so we have an EXACT TIE LOL, who'd have thunk it .

>mutters...'u dirty rat...'
LOL
Seer

 

Yeah Mac, those drivers have different names. and as for the speeds? I thought i saw that someone had managed to get over 1100 stable enough to run 3dmark11.

seer

 

Varu, I ended up ditching the 11.881 drivers completely, they bluescreened for no apparent reason and were just generally more unstable for me.
11.6a is the way to go, at least until we get something new.
seer

 

LOL Nice yo got up here with me

 

I wish I could get settings like the others here, if I clock the memory on the GPU to anything over 850 I get crashes and I can't get much above 780 core without crashing.

 

heheheh, the Rat falls into the baited trap.....

Squeek! What did you adjust to get higher? Oh yeah, you also have a faster cpu then me, lol
