Noobie problem with voltage regulator simulation

Try putting a load resistor from each output to ground. Depending on the construction of the model for the regulator, it is possible that it needs a minimum load.
Lynn

Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of -5.3V, which is still completely unsatisfactory from a simulation package.
I swapped the LM7905 for another -5V regulator, the UPC7905, which gave the correct output but failed after a few seconds. The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output.
So I went back to the LM7905 but that still resulted in the incorrect output.
So Multisim cannot simulate the output of a garden variety, ultra common, component like the LM7905. This is unacceptable.
Perhaps changes to other options in the "Custom Analysis Options" dialog will improve the convergence. If anyone has suggestions I would be most gratefull.
Thanks

Problems with sound regulator in Satellite A300

Hello everyone!
I have weird problem with my sound regulator in A300. When I use "wheel" in front of laptop, next to headphones input etc., sound turns up and down very irregulary- I try to turn up the sound and it twitches around constant level of volume ending at 10% of desired level. I tried to reinstall sound drivers but it didn't work and all in all I have no idea if there are any other things I can do to fix this.
Can anyone help me? Thanks.

I had the same issue with my Satellite U400.
The volume wheel controller was dirty in my case.
I used an compressed air spray and could remove the dust between the sensors.
This helped a little bit.
Now the volume level does not jump too much while increasing or decreasing the volume level.

Problem with BPM Composer Simulation

Dear Forum Members,
When I try to start a simulation from BPM Composer, I get the following error message in an alert: va.lang.NullPointerException ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #13
Does anybody knows what that means?
Regards.

I don't believe it is documented anywhere, but check out the names of the roles in your process.
I've gotten that error when there are either space characters or underscore characters in the role names when trying to run a simulation in Composer.

To buy or not to buy in USA for use in UK , will I have problems with voltage ,should I buy UK cable or just use adapter?l I

I 'm off to the USA shortly and am wondering if I should buy my MacBook pro 15 over there. I will be saving about £300 but will I have to use a UK adapter to charge from power or can I buy a UK voltage cable to fit straight to the MacBook .
I 'm new to Mac but love my iPhone & iPad so would be glad of any advice please.

100 pounds is not a significant savings??? You and I may have different value systems.
I guess that came out a little wrong last time I sent one it was a 13" i5MBP, with shipping, taxes and import it was 78 pounds cheaper than in the UK, 3 pounds for an adaptor for the power supply made it a round 75 pounds, it took 8 days and was in perfect condition so .. you pays yer money and you makes yer choice.

Problem with instrumentation amplifier simulation

I try to simulate a simple example on INA114 with virtual ground.
In the first input I put an AC signal (1mVpk, 100 Hz) and in the other input I put a superposition of the previous AC and an other AC (0.5mVpk, 500Hz).
In the output I expected to take only the AC (0.5mVpk, 500Hz) without the AC that is common in both inputs but I just take the virtual ground voltage.
I have attached the example file.
The circuit seems very simple but I can't find what is wrong with it.
I hope someone here can help me with it.

Hi;
I think there could be a mistake wiring the amplifier. I was looking through the datasheet and here is the pinout of the component:
The pin numbers I think that should be used are the ones in brackets, but I haven't been able to test it.
Here is the link to the datasheet where I found this:

Z77 Mpower + 2500k OC Problem with voltage

win 7 64bit pro
2500k @ 4.6
z77 m power
2x8gb kingston red 1600
2xgtx 780 ref
i recently changed to this board from a z68x-ud3h-b3. But im having a problem where i can't make the voltage drop on idle. I currenly have my cvore set to 1.35 max load during IBT or gaming is 1.344 and degree's are fine. I have C1ST enabled and some of the other power saving features disabled as well as the Hybrid power Offset @ 100%. Is there a option on this board to make it drop to 0.9xx on idle ?? thanks in advance !
PS : is there a way to manually set the dram voltage ? it's currently set to auto but when i try to type in 1.5 or 1.6 it just goes back to auto ?

Club was my cell phone auto correcting.
Was intending to say cpuv and cpu multiplier.
long duration power limit 4096 My z77 = 255
Long duration maintained(s) 1 My z77=2
Short duration power limit 4096 My z77 =255
I set my turbo multiplier to 45 x
Quote
Also do u mean the core ratio limit for turbo multipliers and set them manually too 46 if I want a 4.6 clock and leave multiplier and voltage on auto and I have set then droop to 75%
Yes, although 46x was not stable on mine. Most users report being able to reach 45x w/ all power savings enabled, 46x would require 100% vdroop and most likely disabling some power savings features.

g.drawLine(x, y, a, b);
//Thread.sleep here

Basic noobie problem with image dimensions

Hi folks.
I'm trying to walk myself through a Layer Masking exercise, but I've run into a 'glitch' involving some very basic Photoshop CS3 sizing elements, and I'm durned if I can see what's going wrong.
I've print screened the last stage of my PSD and uploaded it to Alkaspace, here:
http://www.alkaspace.com/free/view_image/a0a4b2304/gearshake.JPG
The screen you see is made up (on an XPP SP3 laptop) of three basic components;
1) 'masking2.psd'is the file I created as background. It's 200mm x 200mm x 72 pixels\inch, RGB, 8 bits and white. But I'm not sure that this file has anything to do with my question. Rather, I think it's to do with one or the other of the two jpgs I downloaded from a tutorial site for the purposes of this exercise. These files are: (not the original names which I think were 'example1 and 2)
2) handshake.jpg 7k
3) gearwheel.jpg 25k
Here's my headscratcher:
Both of these files are 72pi and the same width, 8.82cm. (their heights are different, as you can see)
Both were set at (if it matters) 100% size.
So why is handshake front) markedly different in width from gearwheel (rear), when they're both 8.82 cm wide? Why don't the sides of the handshake image line up exactly with the sides gearwheel?
It's driving me bats. Help would be greatly appreciated :-)
TX

>There doesn't seem to be a choice in the Layer's right-click menu to turn off the "mask facility" without also removing the results of the masking process.
you can right click the mask itself in the layers palette to get a popup menu that lets you "apply" it. that kinda merges it into the rest of the layer.
>And if the Layer Mask is still activated on a layer, how does one then use the paint brush normally on the layer?
in the layers palette, on the masked layer, you can click on either the icon for the image data, or the icon for the mask data. try it. see how whichever one you click on gets a little border around it? that tells you which one will get attention when you paint on the layer in the main image.

Voltage Regulator problem !

Respect to All Experts !
Last month I had blown up my MSI 790FX GD70 by increasing "CPU VDD Voltage" to 1.45volts
I found this review http://www.legitreviews.com/article/1004/6/ relating to my problem bcoz they killed GD70 too by overvoltaging vCore.
According to them some first launched GD70s had buggy MOSFET/Voltage Regulator (9A2S292) which were not able to live at 1.45v. Unfortunately I bought one of them. My dead mobo had same MOSFET (9A2S292).
And then they successfully overclocked another new GD70 with new MOSFET (xxxx298) http://www.legitreviews.com/article/1103/1/
I got my dead mobo RMAed now
I have new mobo, new MOSFET
But this one has a different MOSFET (xxxx294)
I only wanna know if this one is strong enough to take voltage upto 1.45v or more ? Because I've read in many people are ok with 1.45v with this board.
I am stuck at 4.1GHz at 1.435v and I am also very afraid of increasing voltage more than this.
My Computer:
MSI 790FX GD70 (Latest BIOS)
Phenom II x6 1055T 2.8GHz, 125watt TDP
2x2GB ddr3 1333mhz
2xSeagate 500 in RAID0
Corsair TX850 V2 PSU
XFX HD 5770

Quote
What will happen if I increase voltage to 1.45v in "CPU Voltage" and leave "CPU VDD Voltage (MOSFET)" at default ?
Doubtful anyone can predict the outcome. I suppose it's always possible to ask MSI if they will modify your mainboard or exchange it for one with the xxxx298 & what the cost would be?

I have a problem with simulation in Matlab 6.5 and LabVIEW for PID controllers

I have a problem with simulation in Matlab 6.5 and LabVIEW. I have some methods for granting PID controllers in MATLAB to go but not LabVIEW. International Teams degree to transfer two but when I go past the fourth degree no longer work. We changed the formula for calculating the parameters for grade four and gave me some good values for Matlab award but when I put on LabVIEW have not settled. formulas are available in PDF and are. Please help me and me someone if possible. Thanks
lim.4 generation parameters in MATLAB program and comparison methods are for second-degree transfer function.
Solved!

Problem with CPU Voltage

Hello
I build new PC with:
i5-760
Noctua NH-D14
MSI P55-GD65
G.Skill 2x2GB CL7 ECO
Antec TruePower New 750W TP-750
TwinTech GF 9600GT
I have problem with CPU voltage as even when I set it for example to 1.201v in bios, under load it overshot to 1.256-1268. The best is when I oc`ed cpu to 4GHZ and set voltage in bios for 1.30v it overshot for 1.45v+! Not to mention that temps are skyhigh from that. It doesn`t matter if I try to put BIOS Vcore on 1.1v on stock because under load it still rise to 1.16. I turned off all eist, c-state, turbo boost, phase led and switch phase, set vdrop to low and still something is wrong here. I updated the bios under dos from USB stick to newest 1.9 version in order to update CPU micro code without error and it not helped. I want to know is that even possible to fix or should I RMA MB or CPU.
Minor problem is with sysfans as they power on for a second and turn off instantly to start working again when I see list on devices in post. After rebot when my monitor is switched off it takes something like 5 sec to power monitor on and another 5 to show bios, is that normal?

I have similar issues, it's hard to tell which measurement is the most accurate, there are 2 different measurements in the control center that don't match up with the figures set in the bios. The only way to be sure would be to get an expensive accurate multimeter but If you're only interested in running a stable overclocked computer without knowing the exact figures then get the computer running stable and lower the voltages until it starts to become unstable with prime95,
Or you could work the other way round, set the voltages so it boots but doesn't run prime95 for long, then raise the vcore and vtt one at a time until your happy with the length of time prime95 runs without errors. I'd be happy with 24 hours, I seem to remember errors creeping in at around the 9 hour mark on the setting below what I have it set to now.

Problem with multiple output for software simulated project

When a software simulated project in captivate is published more than thrice, the output is not generated properly, i.e not in-line with the project. Is this a problem with my system or due to some settings in captivate which is not activated?

Thanks for the suggestions Malcolm,
They're very handy app's for sure, but unfortunately they didn't fix the problem.
Detour DID overide the routing for iChat's general bleeps & noises, but not the audio stream from video conferences (which is the problem I want to fix).
If anyone has any other suggestions for fixes, I'd appreciate it!
Thanks again,

Real Time Simulation, problem with the 3D Lookup table

Hello,
I have a problem with LabVIEW RT. I want to read under the parameters of temperature, time and voltage, the current out of a matrix.
The matrices differ only in the temperature (first entry in a matrix).
If the 3D Lookup table only get one matrix, I often get "Not a Number" as result. But not always, although the parameters remain the same.
If the 3D Lookup table gets three or more matrices, the result never be "Not a Number". But the 2 other matrices are "dummys" filled up with zeros, expect the temperature. Also the problem appears only if I start the test sequence as Startup on the RT-System. If I start the test sequence from the Front Panel, the 3D Lookup table works well, whether one or more than three matrices!
Its confusing, I know ^^
The appendices contains pictures from a matrix an from the Block Diagram

Hello salomon,
The 3D lookup table is not generated in my code, but is invoked as a constant. I examine the behavior of electrical loads in the cars. Consumers were in a climate chamber measured at various temperatures and these values were packed into a 3D lookup.

Problems with AGP and voltage

HI i have a problem with my VGA card MSI Ge FOrce4 Ti4200 TD8X, the card is agp 8 but voltage in BIOS is 1,5V (like AGP 4). Can anybody help me????????,
Thanks

Don't worry about the BIOS Voltage Being 1.5 (instead of .8 for AGP 8X) as thre is no such BIOS setting for .8 Voltage ..The reason for this is that all AGP 8X Vidio Cards Reduce the Voltage from 1.5 to .8 on the Vidio Cards themselves with the Vidio Cards Own Electronics ......So do Not worry 1.5 Volts in the BIOS is the Correct Voltage for an AGP 8X Vidio Card .............Sean REILLY875

PC-Card (Voltage?) problem with T42P, T61P and X61

Hi!
I´ve got a problem with my LaCie - card, but the card is okay so it´s a problem with my thinkpads.
The card runs ok with my T61P: an external powered FireFire storage is recognized by the thinkpad. On my T42P and my X61 the card is recognized as an texas instruments IEEE 1394 bus host controller BUT: neither the self-powered firewire storage is recognized nor an audio interface (motu ultra-lite km3, selfbowered or bus-powered).
My question: is there a voltage problem on some thinkpads? Any idea what I can do? Another firewire-card? I do have to run the audio-interface bus-powered with a thinkpad, is this impossible???
Hope you can help me!
With best regards,
Thomas
EDIT:
- The audio interface only runs on T61P, but not bus-powered. It only works with power supply - but the port seems to be to slow: "The device is on a bus that cannot support this transfer rate" is mentioned by motu software
So I´m quite disappointed, if I get it right:
- PCI-Cardbus does not provide enough voltage to work with a good audio interface
- PCI-Cardbus is too slow to work with a good audio interface
Any suggestions?
Mmmhhhh.....
Greetings,
Thomas

If until now the Xbox is working wirelessly, the problem might be on the computer side. A firewall update/setting might have caused the problem.
