Sony :: VAIO Z Speedstep

Aug 4, 2009

I just run some test on my my Z46 (P9700 2.8Ghz) and found there is something unusual.

I set the Vista power manager profile to high performance which suppose to give me the max speed of the CPU settings and I check with CPU-z and the reading was 2793.2Mhz which is correct ... however when I try to run some CPU stress test it CPU-z shows the multiplier jump back to x6 (suppose 10.5) and the core speed reduce to 1.6Ghz. And then I start notice whenever I have the CPU on full load it will switch to 1.6 Ghz instead of 2.8Ghz...

I tried it with different software and same happen.. I also monitor the temperature and it's only 65-68 which is normal to me...

I just can't figure out why the CORE speed would drop when it suppose demand the highest speed..

Is it just my Z46 or anything have the same happen ?...

Dell :: Permanent SpeedStep Enabled

May 13, 2008

Here is a brief description of my problem. I have a e1505 w/ a Core Duo (1.66GHz, T2300) My power adapter is reported to me "unknown" by the laptop. (total BS as i know the thing works) and then QuickSet tells me my battery needs to be replaced (this was too soon, so it leads me to believe that the power adapter did something to the battery) But I can't replace those right now. So i'm stuck at a multiplier of 6 (and yes i've disabled all the power saving features in the bios, but the wired thing is windows reports the real speed while other programs such as CoreTemp and CPU-Z report it at being just under 1GHz?)

And to get these things brand new would cost ~$120 (battery and adapter) So is there anyway I can get around the stupid limitation dell has imposed until i can find replacements for these? And, where is a good place to get replacements that won't cost me an arm and a leg?

HP/Compaq :: 6930p "Core2Duo Whine Noise" Has Been Resolved- Without Disabling Speedstep

Jun 12, 2009

I just got a new Elitebook 6930p and its a fantastic laptop other than the dreaded "CPU whine" as some call it. Most uneducated people believe it is the CPU that makes this noise but in reality this has NOTHING to do with the CPU. Its the power components like capacitors and coils that make the Piezoelectric Effect which causes the noise.

I could not bear the whine noise after a few days so I took matters into my own hands. Sure I read about stopping the C1-C4 states in Intels speedstep but thats not a proper solution IMO since battery life will suffer. So how can we mask or cover up this annoying noise? How can we seal it inside the laptop so it does not reach our ears? I have the solution!

Seal it up all the power components with silicon sealer. Silicon sealer is perfect as it does not conduct electricity. These components do NOT generate any heat either.

Sony :: VAIO- If A VAIO Had No Ram Should (if All Else Was Working) It Be Getting POST Beeps

Jan 15, 2010

I have just been given a VAIO PCG8A2M (GRX316MP) , i was told "it's broken but if you can fix it yo can have it" so having a quick look at it there's no sign of life on the display but the lights come on and i can here the HDD heads moving about.

Looking a little more i found that all the ram is missing , so now im not sure if its worth buying some ram to see if it works or not ? The lack of ram would prob explain the lack of display but i wonder if i should be getting POST beeps at least, which im not.

So my question is if a VAIO had no ram should (if all else was working) it be getting POST beeps ?

Sony :: VAIO TZ295N Vs VAIO TZ395N

Jul 4, 2009

I don't know whats the diference (besides the price), between VAIO TZ295N & VAIO TZ395N. Specs in all the websites I've checked say they have exactly the same components: Intel coreduo 1.33Ghz 2GB RAM DVD-RW and 64GB SSD Hardrive. I was wonder if the diference might be in the hard drive interface, with the TZ295N being PATA and TZ395N being SATA.

Sony :: (Old) VAIO Z BD Drive Fit In (New) VAIO Z Series

Mar 27, 2010

I'm wondering if the Blu-ray optical drive (Panasonic UJ-232A) of the (old) VAIO Z series will be able to fit into the (new) VAIO Z series? I would really appreciate it if anyone is able to answer my question.

The reason I'm asking is because I'm seriously thinking of selling my VAIO Z690 & just buying the base Sony VAIO Z (VPCZ112GX/S). I may just be able to afford that base model & the icing on the cake will definitely be the UJ-232A drive being able to fit into the (new) VAIO Z series & work.

Sony :: Vaio CW Or Vaio E Series

Mar 22, 2010

Am planning to get a sony laptop for me. The design simply rocks I am getting mixed reviews about cw and E series. But i made up my mind to get one.

My budget is aroung 40000rupees. Thats around 800$. So suggest me a better one between these two for occasional moderate and less(mosltly) demanding games. I dont care whether its 14 or 15 inch.

Am looking at lower end versions of both the models.

Only difference is CW uses Nvidia Geforce 310 and the E series uses some Radeon 5000 series one. CW has 14 inch screen whereas E series has a 15.5 inch screen. In the models which i am looking at both have matte finish and both has WXGA:1366 x 768 VAIO Display.

which one should i go for. whether the screen quality will be on par to Inspiron one atleast? ( I dont need HD).

Sony :: Vaio F11 Or Vaio E Series

Apr 9, 2010

im planning on using the laptop for videos, photoshop and a bit of gaming, maybe even a bit more gaming :-)

The Vaio F Series only has 330M Nvidia Graphics Card with i7QM and up to 8GB of Ram and up to 256GB SSD.

The E Series has ATI 5650 (a less powerful version, reduced clock speed) combined with a i5 520M with up to 6Gb of Ram and up to 500GB of HDD ? Why can i not choose SSD ?

Sony :: Vaio TT AC Adapter On Vaio Z

Jan 2, 2009

if I can use the AC Adapter of a Vaio TT on the Vaio Z. The standard AC Adapter that comes with the Vaio Z is of 19.5V and the one for the Vaio TT is of 16V, which I don't know if it's enough for the Vaio Z to function properly or if there could be any problem or damage. Both machines have batteries of 10,8V.

I have an undervolted Vaio Z by the way (last multiplier at 0.9875) so I don't know if this could help in any way for my Z to work ok with the TT AC Adapter.

Feb 10, 2009

I have this "problem" since I got my Z. When I start vaio update 3 utility I get this error "messageID=0008" there are no updates for your model bla bla...

However when I go to vaio support page, there are some new updates for my Z590N model (new Bios, USB patch...)

I have checked esupport page where is said if you have problems with Vaio Update 3, to download Sony Shared Library which suppose to contain vaio update utility), I run installation but it doesn't install Vaio Update 3

Now, I can live with this esupport page regular visit updates,

Sony :: Vaio Z, HDD To SSD

Mar 1, 2009

I recently discovered that my Vaio Z will go completely silent (the fan turns off ) after about 10 sec the HDD has turned off..

And, as soon as i click somewhere and the HDD is read again, the fan goes back on. (you can try this by defining the hdd to turn off after 1 min in the power management and closing as much processes as you can,

then watch resource monitor for example, where you can see the disk usage

Sony :: Vaio VGN-FE 41S

May 14, 2010

Time to clean up the basement and digging out some good old comps. I got this Sony a few years back due to its screen sharpness and elegant profile.

The sleek and stylish 15.4" x-black display provides a perfect viewing area. With a strong GPU at the time in GO7600 it was a perfect choice for business and some gaming machine.

Pricing at 1.500Euro-ish, this machine was not competitive in price comparing to others. But its packed specifications and performance can easily justify the difference. The sleek design, the simple beauty and the solid hardware live up to the reputation of Sony performance and quality....
