Silly me, somehow the max. CPU state is at 100% on battery. I must have been forgotten to switch it back to 99%

I'm starting to think that this laptop is not meant to be equipped with a quad core because the fan sucks too much juice from the battery to cool the core.

The BIOS and power options are correct. Some laptops do have this problem from what I've read....

Mine doesn't work after waking up or going back to AC after using the battery At first I thought it's because the new installed 1866MHz Vengeance RAMs but turns out that even with the factory RAMs, it still behaves the same

Hey krazyazy, could you please check your turbo mode? Put your laptop into sleep mode and check if the turbo works after waking up. I'd be very grateful! BTW congratulations for the upgrade! At first, I was thinking about buying the same CPU but at the end I end up with a 240€ 3820QM....

I found out why the turbo wasn't engaged: it's because the turbo is disabled after resuming from sleep or after going back to AC after using the battery! It's like the system can't recognize the current state it's in after a state change. Could you guys please check and report how your system behave?

You're right and I didn't notice that before. It's weird because I used the same power options setting (HP Optimized) for the two tests. This is the new score I got after changing the power setting to high performance: Intel HD Graphics 4000 Mobile video card benchmark result - Intel Core i7-3820QM Processor,Hewlett-Packard 17DF The cores were in full force now. I dont' think so because it shows that the RAM frequency to be 933MHz.

Okay, so here are the results from 3DMark11: hynix: Intel HD Graphics 4000 Mobile video card benchmark result - Intel Core i7-3820QM Processor,Hewlett-Packard 17DF Vengeance: Intel HD Graphics 4000 Mobile video card benchmark result - Intel Core i7-3820QM Processor,Hewlett-Packard 17DF My system performs a little bit worse with Vengeance installed, weird....

I haven't tried 3DMark11 before. Should I?

Yeah, sure, it's at the end of the last page. No problem! I use the latest 3DMark because once I used 3DMark06 and it couldn't display the score because my "graphic card" (which is the iGPU) can't be registered. So, the scores: With 2x4GB hynix 1600MHz CL11: Intel HD Graphics 4000 Mobile video card benchmark result - Intel Core i7-3820QM Processor,Hewlett-Packard 17DF With 2x4GB Corsair Vengeance 1866MHz CL10: Intel HD Graphics 4000 Mobile video card benchmark result - Intel Core i7-3820QM Processor,Hewlett-Packard 17DF Although 3DMark scores always fluctuate a tad bit, the results tell me that the Physics scores are a little better with Vengeance RAM and the Graphic scores are a little better with hynix RAM. That would be against my expectation but I don't know if that means something.

I've just got Vengeance 1866 and it works. Unfortunately 3DMark reported no performance improvement.

Ah, nando why didn't you tell me earlier! LOL, joking! At least now I have two new cool grey sticks with VENGEANCE!!! written on top of them! Anyway, cool info..., and yeah I probably should get an eGPU.

Hmm I wonder why we don't get any from Intel. Anyway, my two 1866 Vengeance have just arrived and after putting my system to the test, 3DMark said that there's no improvement. My scores keep hovering around 60000 and 6400 for the Ice Storm and Cloud Gates tests, respectively. It's a bit disappointing because my system actually recognizes the new RAMs!

Intel says that my 3820QM doesn't support 1866 although it seems that the mobo does. What's more I couldn't find any of Intel's mobile CPU that supports 1866. Now I wonder why they sell those 1866 SODIMM RAMs.... What interesting is, that these 1866 are rated at 1,5V and not the usual 1,35V. Maybe you have to somehow OC your system to enable the RAM operating at this speed?

How did you check it, Aikimox? Crucial says that my (our) mobo supports up to PC3-14900 (1866).
