Here is what I found when testing the new 208 BIOS for G750JX

Scheduled BIOS Flash via WinFlash, rebooted - flashed new bios - booted into Windows - logged in - SHIFT-CTL-ALT rebooted to check UEFI changes - didn't notice anything new except version number, booted into Windows.

Set CPU/GPU to default/stock settings (Intel XTU / Asus GPU Tweak) - so was running at 3.2GHZ CPU 797mhz/4008mhz GPU.

1) With AC plugged in, started PRIME95 with 8 threads, task manager showed 2.98ghz 100% CPU

2) unplugged AC cable power from laptop, power plan automatically switched from Power4Gear High Performance to Power4Gear Power Saving, task manager showed 1.49Ghz at 100%, everything seemed ok.

3) Had jerky mouse, didn't think anything of it as PRIME95 can do that, although I hadn't seen it before on the G750JX, but when I selected power plan Power4Gear High Performance while under battery mode CPU went to 2.8ghz, then the mouse froze.

4) Had a tough time getting mouse control long enough to make any change, so I plugged in the AC cable, and after a couple of *minutes" I was able to click through and end the PRIME95. Mouse control still was jerky for while.

5) With PRIME95 ended, while waiting for mouse control to come back, I noted the CPU speed drop down below 1GHZ, usually it doesn't drop below about 1.2ghz while idle.

Then I tried a series of tests trying to see if responsiveness could be found with Power4Gear Battery Saving mode while running 4 threads of PRIME95 - no such luck.

After a couple of more tests, with reboots in between to see if that would help, I thought I should go back to 207 and try the same tests and see what happens.

While I have been writing this I am back on BIOS 207, on AC , on Power4Gear High Performance, running 8 threads of PRIME95 + Intel XTU 3.6ghz + Asus GPU Tweak 932mhz/5000mhz, and no lag, freezing, or other non-responsive symptoms.

I unplugged the AC from the laptop, screen dimmed as it switched to Power4Gear Battery Saving, still running the 8 threads and still at OC settings, with no lag / unresponsiveness - but of course the CPU speed dropped to .79ghz, and GPU dropped to 135mhz/810mhz.

Before this I had set up ThrottleStop 6.0 BETA to run on battery at reasonable speeds above .79ghz, in case I need to run on battery, which isn't often.

I don't have ThrottleStop set to run at boot time and to automatically set values at every boot - so it wasn't part of this test. But, I thought I should mention that I didn't see any mouse freezing or unresponsive behavior while using ThrottleStop at any value I set.

I am not recommending ThrottleStop, and I am not sure it is safe to override settings with ThrottleStop in short term or long term use.

Given the CPU speed difference between Power4Gear Battery Saving / High Performance (1.49ghz vs 2.8ghz peaks) it looks like Asus is doing some fun on the fly tuning that might be causing problems under CPU load extremes in BIOS 208... I might wait till 209 shows up with some tuning changes before I try again.

Please post your experiences / what you see after going to BIOS 208 (you can always revert to BIOS 207).

And, JH guys, what are you seeing?

Just my 2c - after updating to 208 on my JX, I have absolutely no issues at all. No need to throttlestop any more on battery, otherwise it is working same as always. I don't use power4gear though, just the builtin windows power centre with some customized schemes. All in all, the last minor annoyance I had with the laptop is now gone.

It's funny! I had press repeatedly the F keys and now PC gone! Now I'll try restart... What happening?
