HP DV6 QE (6770 Ati) (i7) and 90W adapter. Little review.

So, i really like this laptop, but one thing pieces me off, gigantic brick-adapter. So i ordered slim one from ebay,
OEM GENUINE HP 90W SLIM POWER LAPTOP AC ADAPTER BT798AA | eBay





Its fully compatible with my laptop (sign) and it works perfect, except i see some performance drop in cpu dependent game, like gta 4:

On slim adapter:

On default one:

I moved my brain and used ThrottleStop,
ThrottleStop - Performance Adjustment Tool for Core 2 / Core i CPUs
to lock cpu, and it worked!

Now i have same performance like on default brick but on slim adapter.

 

What do you lock the cpu at? How hot does it get?
Mine gets 92 degrees playing games normally and I have
the 2630qm, that's hot.
Wish I could lower the voltage to the cpu, I doubt it needs
all that juice.

 

Just use coolsence for cool mode. You will have 80c

 

And a slow cpu down clocked. i7s should run over 3 ghz,
my laptops is 2 ghz with turbo up to 2.6 ghz, not that fast.
If I coolsense it to cool mode, I will probably be running at 1.6 ghz,
or the same speed as my 6 year old computer! I PAID for the speed,
it should run under 80 degrees at its normal default speeds, HP used
a poor cooling system I guess, even though it sounds and feels like a hair dryer exhaust. I have a feeling it is way over volted.

 

1) you would be running at 2ghz on all 4 cores with coolest mode

2) per clock per core, sandy bridge is much better than even the last gen nehelem or arrandale, let alone ur 6 yrs old tech. 2ghz on ur 2630qm not only has 4 cores vs the 1 or 2 cores from ur 6 yrs old machine, it also work much faster than it even if it was 2ghz also.

3) 2ghz on sandybridge is more than enough for anything you would throw at it considering your comment about the cpu.

 

Do you have any idea how turbo mode works? Base clock is 2.0 per core. Turbo will boost up to 2.9 on one core. It goes down from there as more cores are running (multi-threaded apps). Coolsense just disables turboboost on coolest mode. It won't throttle down your base clock.

You can't compare it to a 6 year old processor. Only a newb compares clocks between C2D and Sandy Bridge.

 

I know the difference in architectures, but a C2Q from a few years ago running at 3.6 ghz is faster than a 2.0 ghz 2630qm, especially in single or dual threaded games, which most are.

Anyways, if I lock my cores at 2.0ghz with coolsense, there would be no difference because in a game that uses
all 4 cores (or 8 hyper), such as Rage, my cpu under performance gets 92 C on all 4 cores, the fan is hot and loud,
and obviously the cpu is automatically taken out of turbo and all 4 cores are forced down to running at 2.0ghz anyways, performance mode is not going to allow 4 cores to stay at 92 C and turbo up to 2.6, 2.7, 2.8, or 2.9 Ghz. Coolsense
will only make the laptop cooler when you are not fully loading all the cores, so what is the point? I don't need it to
be cooler when it is under a slight load or using 1-2 cores, I need it cooler when it is fully loaded on all cores, and I
don't want to sacrifice performance for it. I have a 4.7ghz i2500k system (non-hyperthreaded) and it pisses all
over this i7 hyperthreaded 2.0 ghz 2630qm. Mhz makes a huge difference with these new processors, even at stock speed the i2500k at 3.2 Ghz trashes the i7 at 2.0 ghz, except for 3 multithreaded business apps that no one uses on a laptop anyways.

 

Oh, your desktop processor destroys a 900 dollar laptop? No way, I never would have guessed.

 

Wait... I think the i2500k and the 2630qm are both sandy bridge.
And yeah, a cpu with a TDP of 95W can be faster than a laptop cpus which is only allowed a TDP of 45W. The question is: Is your i2500k (at stock!) more than "two times" faster than the 2630qm or not?

 

um... you do realize that on this laptop, for any games that might have low fps, the cpu is NOT the bottleneck right? e.g. you aren't going to get any fps gain going from 2630qm to even 2920xm... regardless of if it is optimized for single, double or quad cores.

you also have obviously not tried to stress the cpu on coolest setting... it does NOT get to the same temperature as it does on performance mode.

of course your 2500k at 4.7ghz is going to be faster... it has the same performance per clock as the 2630qm... as both are sandy bridge... and one has over twice the clockspeed of the other...

your other statement of a 3.6ghz c2q over your 2630qm is probably not true. did you actually run benchmarks or did you just pull that out of nowhere?

 

I saw benchmarks on cpu test sites reliably showing 100 cpus, 3.6ghz c2q over 2630qm is true. And I agree most games are GPU dependent, but GTA IV and ESPECIALLY RAGE! are CPU dependent. Rage maximizes all 4 cores (8 threads) to do all the cpu and texture streaming. My 6770m easily does 60fps at 1920x1080 in Rage without overheating, I can not say that about the cpu.

 

What does this even mean? It makes no sense. Either your computer pulls 60 FPS in Rage or it overheats and shuts down.

It doesn't seem like you have any idea what you're talking about.

And as for the stuff about a 3.6 GHz C2Q, there was never a C2Q that ran at 3.6 GHz stock. So you must be talking about an overclocked desktop processor. Which is ridiculous.

 

He's saying that his GPU is able to run RAGE at 60fps without overheating but is CPU is unable to keep up due to lower frequencies (i.e. a cpu bottleneck). Makes sense to me.

 

Actually, notebookcheck has a whole lot of benches. And as you can see, the "puny" 2630QM does fairly well against old desktop irons.

 

If his CPU can't run the game, how does he know that his GPU can do it?

I understand what he's trying to say, but A) there's no way Rage runs at 60 FPS on 1080P on a 6770M, and B) It doesn't make any damn sense in practice.

 

Reliable cpu test website benches 100 cpus,
c2q at 3.6ghz is faster than 2630qm at 2 ghz.
And Rage is CPU bottlenecked, not GPU. The 6770m
runs it at 1920x1080 at 60fps, you need aa to get it to drop.
But the CPU is using 8 threads at 100% and 92 C for its texture
system, so yes, most games are limited by the 6770m, but a lot
of the new ones coming out will be based on id 5 engine. And there
is GTA IV, and other Starcraft, etc. cpu dependent games.

 

A C2Q at 3.6 GHz is a watercooled desktop processor. Why can't you understand that?

And 92C is not overheating. 100C is overheating.

 

Well if 92C is not overheating, it is definately shortening the lifespan of the cpu. And yes, I can run Rage at 1920x1080 with the 6770m 2gb at 60fps with no aa. If I turn on aa, then it starts limiting the framerate due to the GPU. I put the rage driver over the hp driver and it does seem to crash every so often, but I can play it for about 15-30 minutes at a time, that is why I thought the cpu was the problem as it is blowing out burning hot air and crashing with 4 cores at 92 C!

 

Easy. He's getting 60 fps -> temp rises -> CPU throttles -> fps drops. Whether he's getting 60fps to begin with I don't know, but it's plausible.

92c is pretty high, hotstocks, you should get a cooler or repaste or something.

 

i7-2630QM (2.0GHz) ~ i7-920 desktop (2.66GHz) > Core 2 Quad QX9770 (3.2GHz)... NO need to worry. CPU speed means little compared with the CPU's of several years ago. It's all about architecture.

Passmark:
i7-2630QM = 6335
i7-920 = 5567
Core 2 Quad QX9770 = 5018

Cinebench 11.5
i7-2630QM = 4.7
i7-920 = 4.81
C2Q QX9770 = 3.94

PCMark Vantage
i7-2630QM ~ 10000
i7-920 ~ 9000
C2Q QX9770 ~ 5500

With the DV6, I say get in there and repaste. I did it and it dropped temps like 5-8C at peak (with AMD CPU however, but same cooling system).

 

I think it's far more likely that he has no idea what he's talking about.

 

I know what I am talking about, and I do get 60 fps till it crashes, less driving around though. I have been building computers for 20 years, hence my perfectly stable 4.7ghz monster which never gets above 70 C.

P.S. I do have artic silver 5 and I wish I could re-paste my laptops cpu, but I have never worked on a laptop, and don't want to ruin it. I watched a video on how to do it, and man did it look complicated and delicate. It looks like I would break thin cables or wires and never get it back together properly. There HAS to be an easier way to re-paste than on that video. Besides, my laptop is brand new and if HP thinks 92C is acceptable and intel thinks 100C is acceptable, then I am ok with my hairdryer, I mean laptop, seeing as it only gets this hot with games or stress testing. I heard pasting doesn't even help usually, but drilling air intake holes in the bottom by the fan helps temps a lot, but then again, I am not about to do that either! I also heard using the 9 cell battery raises the back up off the table and lowers temps. I live in Michigan, people are using this laptop in Florida, Texas, and Nevada where it gets 110 F outside, if there were problems I am sure they would have them.

 

i'm going to tell u right now that your crashing is not because of your CPU. 92C is indeed not TOO worrisome, but it's ridiculous to compare that temp with your desktop... laptop temps and desktop ones are not even REMOTELY comparable.

just wait until amd releases a better rage driver and that should fix all your issues.

 

Your desktop processor is completely irrelevant.

 

So you have all gone off on a tangent. Whats the final conclusion of using the slim adaptor? Does it get too hot or put the laptop in jeopardy?

 

no it doesn't. i've been using a 90w slim adapter on the go and keeping the 120W at my desk for about 4 months now. it works perfectly fine.

the adapter gets warm, but that's about it.

 

Is the slim adapter lighter than the normal one? If it is, I can buy slim one to keep in my travel bag and leave the normal one at desk.

 

much lighter. it's about 1/4 the weight/size
