I was actually going to post that as well. Although I was able to get solid fps in crossfire with the right drivers and settings, I got better fps with just the 6650. I also noticed you updated your gaming profile. I'll probably try mine at the same since your machine and mine seem to have the same range, while other volts I've tried on recommendation BSOD'd.

I think the comment made way back in the thread about CPU core OCing taking throughput needed for the 6520 in crossfire was correct. I also think the benefit in most games from the CPU overclock makes better overall frames without crossfire than the added GPU core does at stock clocks. Hence the better frames without.
I've confirmed this in Crysis 2, RIFT, Alice: MR, Fable III, Deus Ex: HR and Fallout: NV. Some of those are DX11 games and some DX9, but they all run better with single over crossfire, though the difference is less if running crossfire and stock clocks in the DX11 games.

Hi guys. First things first: this laptop is awesome, best laptop you can buy today in terms of performance/$, especially for gaming.

This is my third Asus (had a G60JX and G73JH, vastly more powerful than this but also more expensive) and I had an Alienware M17x R3 6970m...

Yet this laptop still pleases me to no end. Love the overclocking, love AMD's efficiency, and the Crossfire with IGP/dGPU is genius. I've been wanting a 15.6" like this for a while.

Now, here's a question for my fellow overclockers:

After adjusting voltages in K10Stat, I've been stress testing my P0... @ 2.1, 2.2 Ghz and 2.3 Ghz, stress testing via Prime95 Large FFT's is going fine...

Except after 2-5 minutes, consistently, every time, core #3 fails the test. Even though the temps are anywhere from 72-77c depending on voltage, core #3 keeps failing. IntelBurnTest has no problems with core #3, but Prime95 just errors it out every time.

Is it safe to assume my 3rd core is probably faulty (at least when overclocked) and I should go exchange the laptop? Just bought it today and I'd rather be safe than sorry, and get one that has decent O/C capabilities.

I have a similar situation, when testing my temps are low 70s, and core #3 gets an error in Prime95 (rounding error) when I try to drop the voltage down to 1.075 at 2200; however it works on IntelBurnTest. I get no errors at 1.0875 and 1.1v at 2200, in either Prime95 or IntelBurnTest, so those seem to be, for my CPU, OK voltages.

What frequency and voltages, paired with 2.1,2.2 and 2.3 GHz are you trying when core #3 fails?

It's been a while since I've overlocked, things have come a long way.

If SiSoft Sandra says I have 2 memory channels, am I running in dual channel? I bought the cheap gskill memory stick from newegg. CPUZ didn't have anything in the dual channel field.

Thanks!

any cooling modifications ? ? ?

anyone know what sorta access we have to the cpu for thermal coating?

[r0ge]

Finally got my cores stable at 2.2Ghz. Had to crank the voltage up to 1.1 to get core 3 to be stable. I played a good hour of BC:2 and it performed fairly well.

Thanks for the tip on locking the cores when testing Wingnut.

Now to mess around with this GPU mess.

It shouldn't be running hot at the proper voltages. I'm running mine at 2300/2600 when gaming and not breaking 73C. Several other people have gotten even higher speeds at lower voltages.
If you're running at similar settings to other successful ones you've seen here and your CPU is still overheating, you might consider exchanging it at the store.

As to pasting, hold on, I'll shut down, flip it over and take the panels off and find out.
EDIT: I would not recommend opening the casing on this laptop. I got the back panel off, but the plastic could have easily cracked at several points with the slightest slip. Once the board is exposed, the heatsink doesn't look too difficult to remove. Looks the same as any other laptop heatsink. I didn't actually remove it because mine is running just fine, so I don't want to break the seal. If your CPU is running too hot, it's not worth voiding the warranty by leaving evidence that you opened it up.

I have 2.4@1.1ghz stable, and after an hour or so of COD4 it will hit upper70's lower 80's...you think that's normal? and How can I stress test my GPU? I haven't had any problems at 700/1000, so should i keep bumping it up and playing games until it locks up?

The CPU is rated up to 100C, so you aren't doing damage. If it's causing throttling, it's a problem, but if it's running fine with no BSODs, you should be okay. Mine stays under 75C, but I could be in a cooler environment with better airflow and running less demanding settings on my games.

As for your GPU clocks, from what I've heard 700/1000 is the sweet spot. That's the other reason yours is hotter, I'm running 11.8 drivers so I'm at stock GPU clocks.

Honestly, don't even bother with Prime95, it seems to be an anomaly. I stresstested my newest overclock of 2.73 Ghz @ 1.185v with 3DMark11 (which WILL fail any unstable overclocks very quickly) and 6-7 hours of Deus Ex: Human Revolution and it was absolutely fine. Temps were at 75-80c.

I think Prime95 just has a really weird issue with these CPU's... if everything but Prime95 is stable (and several things that tax the CPU even harder than Prime95) and it's that same Core #3 failing... I really think it should be dismissed as a strange anomaly and error. I'll go test my 2.73 Ghz overclock right now with Bad Company 2 and see how she does, but I'm guessing it should be stable .

There's an easy way to prove if Prime95 works properly. If Prime95 shows no errors at stock settings, then it's not an error with Prime95.

The danger of dismissing Prime95 as faulty is that the laptop may slowly corrupt data over time.
