If you are using an Nvidia card your physics score would be higher if the setting is enabled in 3Dmark. You have to uncheck it to force CPU only physics.

Well,...as much as like the responsiveness of Windows 8.1, have to go back to W7. Microsoft is doing a great job at taking more and more control away from the end user. If that tendency continues I'll have no choice but to switch over to linux entirely. We are entering a grim era of control instilled by world's leading corporations.

Awesome temps Bro! But your ambient/room temp is really low BTW, if you are using eGPU, your CPU temps will be even lower. My CPU draws an extra 15W for the IGP part during games.

I followed the noble cause and sent him an email. Not hoping for anything but who knows. You gotta try. you miss 100 of the shots you never take

Here's a screenshot. Running @3632QM clocks, normal computing, browsing, etc. No elevation, no forced fans, no chest freezers. I don't hear the fan at all. Even the vent is cold to touch, lol

I have a 8470p bios dump. Will give it a shot but need to do some serious prep first, just in case. Here's what puzzles me,.... while the 35W BIOS restriction applies to every bench and test I do, there are moments when the machine stays idle and the OS starts some kind of low level maintenance process, which uses 45W! The temps go up to 94c and the fan is at full blast. HWinfo64 and other tools detect the exact same numbers, max clocks - 3.6quad-3.8single, 45W and high temps! So the OS does have access to all 45W! If only there was a way of forcing the OS use all the juice. If we can solve this mystery, no need to flash the BIOS!

If we had access to the CPU voltages, you could undervolt it and slash another 10c without affecting the performance. Alas, this still remains a dream unless someone is brave enough to try cross-flashing BIOS from another model like Nando suggests. I'll probably give it a shot at some point, but am too dependent on my machine nowadays...

For sure, you will probably see about 0-5c difference but at the expense of 8x600mhz = 4.8Ghz total. Note that 45W quads operate restricted to 35-40W in our machines. That's why the load temps are tolerable. My 3360M hit 90C+ in prime same way the 3840QM does. The cooling mod was maybe about 5W total if I'm very lucky... Nice temps. Did you force the fan or let run at stock settings (BIOS controlled)?

Well, if you really want a cool running machine at 3632QM level of performance, - go for a 45W quad and reduce the clocks. When I don't need the full power I simply set the max CPU to 99% in advanced power settings. That way it performs equal to a 3632QM running at full load but the temps never reach 70c. In fact my idle temps are around 35-40c and I almost never hear the fan, like... never, unless running benchmarks or games.

Tried a few more tools just to make sure I didn't miss anything: RMClock, Throttlestop, CrystalCPUID, CPUGenie, etc. All in vain, the CPU is completely locked down in BIOS. So is that it? Is 200mhz via BCLK all we can really do? I read about recent attempts to flash HP (RSA signed) BIOS but even those who succeeded had issues afterwards with random lockups.... I wonder if it's possible to completely rewrite the system BIOS (using the stock one as a reference) without invoking the RSA checkup? I wouldn't mind paying for the job. Would even spend some time to learn BIOS programming (have some basic knowledge of C/C++, PDP-11),...if there's a hope.... What saddens me is the fact that we could probably get an extra 600-700mhz@8threads out of our quad cores with a right combination of unlocked multipliers, undervolting and other power settings while having similar temps to what we have now! Not to mention the ability to use third party Wireless and WWAN cards like Bigfoot Killer and Intel's latest 811.ac... *sigh* You can't really have it all, can you?

Sounds like a good idea to me. Though I'd probably tag it as IVB XBook 12, hehe. But I see your point and completely agree!

Yep, check out this review. I ran the same tests on my machine and got a better IGP and more than 2x higher CPU scores. And these are their new 14"ers....

And no full voltage socketed CPU's in portable business machines. Only Clevo but their overall build quality is sub par to Elitebooks, and no NBD warranty. Looks like for the next few years there's really no reason for us to upgrade...

Very good results! You should see an extra couple of degrees difference with a quad and higher RPM. I'll try your mod for sure.

I always run the blend (default) test. Also wprime 1.55 32MB and 1024mb (set to 8 threads).

weird indeed. Try cpu only tests like Prime 95, wprime 1.55, cinebench r10, r11.5 Edit: How do you like them bananas : 3dmark06 3840QM/HD4000 3dmark11 3840QM/HD4000

Nice job! So, what's the difference in temps?

So what would be the fastest RAM for our machines? As I understand the system won't accept and anything above 1600mhz and will revert to 1333mhz. Please share your experiences, guys!

Too much work imho. I used a torque force of a screwdriver and it worked. As for residual glue if you care about it, use sanding paper + xacto knife => less than 5 min of work.

Possible, I removed a second heatpipe after gluing it with AC thermal adhesive. Just need to apply some force

Well, maxing out the fan with TPfan control really helps. I've just finished a 3 hour gaming session (Crysis and a few other games) and the max temp was about 77c which is perfect. But there's definitely some more room for improvement. But it's not just more copper, it's more thin copper with a lot of surface area and easy to dissipate. Otherwise you will only slow down the heat but once it gets to the critical point, it will be very difficult to control. Awesome stuff, keep us posted. Every degree counts in this business!

Ok, guys, I ran a few stress-benches (wPrime 1024mb and Prime95 10min). First of all, the temps are now completely adequate. Under full continuous load the system settled under 89C in Prime. That is with the fan at full blast and stock BCLK. With a back plate removed the same test showed 81C max. Same test at 104.8 BCLK - 82C max. So, drilling holes in the cover would definitely bring some improvement but no more than a couple of degrees. Still, I might do it just for kicks. Here are the screenshots: 1. Stock clocks, Maxed out fan, wPrime 1024mb run: 2. Stock clocks, Maxed out fan, wPrime 1024mb run, no back cover: 3. BCLK @104.8, Maxed out fan, wPrime 1024mb run, no back cover:
