PLZ. There HASWELL ask you about low-voltage processor notebook CPU problems

My notebook is DUO13，I7 4650U, with the core graphics HD5000, now found such a problem.
The BASE itself I7 4650U frequency is 1.7, in theory, can go to the highest frequency dual-core 2.9
Running some games when we get LOL example, a start frame at 55-60 or so, this time to look at the CPU frequency at 2.8-2.9.
After 1 minute, reduce the number of frames to 45 and down, this time to look at the CPU frequency back to a fixed frequency of 1.7 BASE up. Then I cut backstage Desktop 2 minutes, then cut back is 2.8-2.9 over driving games over one minute back to 1.7
The power management options inside no problem, that is, high-performance option, power on, only this time the whole temperature 60-70 degrees, everest did never even prompted high frequency reduction, it is impossible is the temperature problem. .
I would like to ask what is the problem then? Does your CPU in this case whether smoothly to maintain a high Turbo?
THX.

 

You are having CPU throttle issue. You can try a utility names ThrottleStop, but I really not recommend because the cpus already reach 70.
Those CPUs are Ultra Low Voltages, so I would not expect they can do the same as higher voltage CPUs which can run at higher clock.

 

I know, I have used ThrottleStop, ThrottleStop_600 version. However, no how. From everest which also no hint that i having CPU throttle issue, because the temperature is very low. I am very curious about other models of laptops, such as FIT 15/14 whether it will have the same situation, they also use ultra-low voltage processor.

 

Can you post a screen shot of the ThrottleStop Turbo Power Limits window?

The U CPUs are like 2 or 3 different CPUs with different specs depending on how a manufacturer decides to set them up. ThrottleStop can let you make some adjustments in that window to maximize performance.

Edit: Here is some more information that explains this part of ThrottleStop better.

I tested GW2.I do not know why there is like this 5 Figure same situation.




Because the fourth-generation processor is not very compatible with the software?

Or is it because I only 45W power adapter power?

Then this figure, we can see the beginning frame is relatively high. It runs on a high the whole time on the TDP. But after several tens of seconds will return to the situation of Figure 1.At first this time, GPU portion can be maintained at 750-900, GPU part of the power in 16W-20W. Then overall CPU TDP can be maintained at 25-30.
But this lasts only one minute. After the GPU on the back 500-550, gpu power consumption will be reduced to around 10W, the overall CPU TDP will be reduced to 19W



But if I simply run a non-graphical portion of the CPU TDP test, he can be stabilized at 25W and down. Than 19W when playing the game to be higher.

Anyway, thank you very much

 

Intel designed the Core i7-4650U to be a low power processor with a long term TDP of only 15 Watts. This power has to be shared between the Intel CPU and the Intel GPU. Long term, that's not enough power to run both of them at their full rated speed. You would need a laptop with a Core i7-4600M which has a 37 Watt TDP to run both the CPU and GPU at full speed.

For gaming, I would set the TDP Level Control to 2 and the Intel Power Balance to CPU=0, GPU=31. I would also try reducing the Set Multiplier value to less than 20. This will reduce the power going to the CPU and might free up a little bit of extra power for the GPU so it can run faster.

Unfortunately, low power U CPUs are very limited and there's not much you can do with them.

 

This is what I said above. Unfortunately, he doesn't have an option for higher power on VAIO Pro which only runs ULV processor for long battery life.

My brother picked up a Vaio Pro 13. He updated the Bios via the Sony Update program and got an error before the installation was complete. The computer now will not boot bios, windows, anything - even with assist button.

Sony acknowledged the problem saying that it has happened to other users. He wants to fix this himself if possible...

Is there anyway we can get the Bios reinstalled on his machine? This is like the 5th problem he has had with an almost new computer, and it is shocking. This is on top of problems with the trackpad, touchscreen, and WIFI.

Thank you for any suggestions.

 

sony can tell me their DUO13 long-running case in TPD25W. According to my tests, when only running non-graphics processing tasks, can indeed reach 25W, but if you need to run the game so the graphics processing tasks, but only to around 19W. This count is that we cheated?

 

The facts tell us over most of the hardware is not another strong indicator for playing games, except the power to keep up.

 

You can find Sony customer to the original BIOS do? Official website does not seem to provide the original BIOS.

 

He is ok with getting the updated bios on his machine. However, how would we go about flashing that?

What is the best way to get the bios on there?

Thank you

 

I have read somewhere in this forum saying with Insyde, there may be a recovery option.
However, it is also depending on brand to brand. I am not sure, which bios of vaio pro comes with.

 

I have heard of Insyde before, but is it even possible to recover the BIOS without having any screen or command prompt?

 

They have a combination keys need to press during power on to launch recovery mode and read bios from usb thumb drive.
