CPU Upgrade again! ^^

Hihi to all, I have VGN-FZ190FE with a T7300 processor ... searching I found x7900, and the only difference between this and all the T7x00 scale is for heat support.

Maybe any problem with this difference ? .. I mean 35 W and 44 W for TDP ??

 

You also need the processor support, int other words, your laptop BIOS should support the processor to use it properly, also if I remember correctly, you will be paying a lot of extra money for an x7900 because it has unlocked multipliers and very few laptops support overclocking of the CPU by multipliers which I don't think happens to include your laptop.

Anyways, are you sure that you will be needing the speed upgrade ? Unless your job is CPU-intensive (Aka, the CPU is the bottleneck for the performance), the CPU upgrade is not going to really make a difference.

 

Game support is the Answer!... I can run games but with slow fps! .. and I dunno if bios support it .. that´s why I asking for! ... cand u help me to find if really can I ? ... or I take just 7800 one ... It needs the same Watts !?

 

You must go and see if your laptop has ever shipped with a CPU that uses that much power, otherwise you will have problems with cooling as well as the power supply with the CPU, because you are increasing the power consumption of the laptop and that's not what it was designed for, at worse, it might actually do some damage.

On a different note, much of the time, the bottleneck for the gaming performance is a weak GPU, not a CPU, upgrading the graphics drivers also helps. And upgrading GPU's is not possible for your laptop. (For more information visit the Gaming forum about the drivers and the GPU)

 

Why stick with a 7xxx series processor.
Your system should have no problem supporting the T8100/T8300 processors.

I am not sure what support is for the T9300, T9500 processors, but they should work.

When you are gaming, have task manager open in the background. If cpu load is 90% or higher when gaming, a cpu upgrade will help. If the processor usage is like 40% when gaming, than a cpu upgrade will not increase game performance.

The problem is your 8400M GT, and no CPU upgrade will solve that for you.

Better to save your money for a notebook with a real gaming GPU.

 

QFT. It doesn't matter how good your processor is; your video card is the bottleneck. There will be almost no performance increase by upgrading to a better processor.

 

Yes
When am playing Blu-ray the CPU is on 20% usage

 

Ok thanx for all your answers! ^^ ... I think I´ll go to save money to complet upgrade laptop! ^^... but If u wanna share more comments .. don´t be shy about it! ... I learn a lot whit this kind of comments ^^ ...

thnx to all! ^^

I add info about my notebook, if anybody can help me more with this data ^^ :

System Report

Please somebody can comment something more watching my system report please ? ^^

 

can you explain this?

 

Well, the CPU has a base clock, for example, the default clock of the X7900 is 200MHz, it is multiplied by the multiplier to a higher frequency, which is 2.8GHz.

Usually a number of CPU models, for example 4 differently clocked processors of the same family that are released at the same time, are actually made of the very same silicon, they are tested, and the one's that can meet the power requirements and the stability at a required clock (aka. Have a better quality) are locked (using changing some data on the CPU, or by burning some internal fuses in it) to the higher frequency, and the lower quality one's are locked to lower frequencies, so the multiplier cannot change.

Now, as you may have guessed, many processors that are locked at a lower frequency, are also perfectly capable of running at higher multipliers, but the reason for the locking is the business model, if they are not locked, people can get a cheaper CPU and set it on a higher multiplier, thus hurting the CPU maker's often far higher margins on profit.

So, Intel releases some of the high quality processors, without their frequency multipliers being locked, allowing the users to change it, but the motherboard should support that particular CPU, so it can set it's settings properly in the BIOS, and it also must be able to support the power it requires in this case. And, as far as I know, the only way of overclocking a CPU by increasing the multiplier on a CPU with an unlocked multiplier is to use some BIOS menus, which should have been programmed into the BIOS, which is not the case for most laptops.

 

OK I knew that, but I'm glad I could read it again so I could verify my info. But, SpeedStep changes multiplier on CPU regularly, I think it is kinda old technology.
Maybe I read something wrong in this thread or something.

 

Well, like some people pointed out, your GPU is "NVIDIA GeForce 8400M GT", which is not good for any kind of heavy gaming, the CPU is not what is limiting your speed at games, the only way of increasing your gaming speed is to use more up to date drivers, and that's about it.

Speedstep reduces the clock on-the-fly, it is configured by some power levels in the CPU, which is ultimately controlled by the software, the reason for that is that [I made a slight mistake in the post above] the lower multipliers do not get locked, so the CPU can dynamically go to lower clocks when the processor asks for it.

 

ok this clears things up, I was confused
