Help.. Voltages !!

Hey, my core voltage is 1.70 and the aux voltage is 1.23 , is this normal or am i screwed?! :D ?( )
Please help. Anything.

Is the PC running stable? If yes, why wonder about the voltages. Only look at those if you have severe problems.

IPhone 5 brightness permanently reduced (Please help, voltage issue??)

Hello,
I really need someone with high expertise to help me. Obviously i appreciate any help given but please dont say point less comment like reboot the phone or turn autobrightness off.
Here is the issue:
I have had several iPhones, right from the first to the 5. Lucky me. But i have always had the same issue. The screen brightness is significantly lower than any other iPhone that I compare it to.
Now i have the iPhone 5, if i compare it to anyone elses the brighness is much lower. Autobrightness is off. When i first got the iPhone the brightness was like everyone elses.
i only use the official charger. I think there may be a problem with the voltage or the electricity in my home as all my iPhones have had this problem. Im not sure when the change happens but the something is damaging the backlight of my iPhones. No idea what.
Please can some one with the same issue or knowledge of physics please help me. I dont want to keep having this issue. I also have a Macbook pro and am fairly sure its happned with this also but have no means of comparison as I dont know any one else with one that comes to my apartment.
Regards
Fahad

The iPhone 5 has full Warranty. Make Genius reservation and take to Apple Store. Show the Genius the problem and they will replace your iPhone 5 with a perfect iPhone 5 without problems. If some of iPhone 5 have this problem, it does not matter, Apple makes millions of iPhone 5, some are going to have a problem. When the Genius gives you the new replacement iPhone 5 test it out in the Apple Store before you leave, so you are happy and do not waste anymore of your time.

Moving to Uk and Need help with Voltage Issue

Hi
I recently (less then a month) bought a new Intel based iMac (17/1.83/512/160/COMBO/AP-USA) with built in iSight, and now I am moving to UK for a year. I want to take my iMac with me. Can someone help me with true answer on how to solve the voltage issue. I did some research on here and else where but could not come to any conclusion yet.
I found this article http://docs.info.apple.com/article.html?artnum=75099 to know if my iMac has auto-switching voltage and also this article http://docs.info.apple.com/article.html?artnum=301724 to determine which iMac I have but still cant come to any conclusion yet.
This will really help me to decide if I should connect directly to power outlet in UK or will I have to buy a power converter.
Thanks in advance!

Hey guys,
Thank you very much for your help. I am well aware of plug/pin adaptor to connect US plug in to UK outlet, I have been UK and Euro frequently but always with my Macbook which never had any problem cause all notebooks comes with power adaptor. This is first time I will be going with iMac that doesn't have power adaptor to convert voltage.
All I need to know can I just plug directly into wall outlet or will need a convertor in between. I am not sure is my iMac has auto switching inbuilt.
Thanks again

Using DAQ-assist to input a waveform; need help building a counter to count voltage "spikes"

Hey all! I'm pretty new to labView and even newer to this forum, but its nice to meet you all...I hope that perhaps someone can help me with my problem.
Allow me to begin by detailing the specifications of the problem. I am an undergraduate student, and have a job doing research in a MEMS (micro/nanotech) lab. The graduate student I am making this program for is working on biomedical applications; eventually, the program will be connected to a microdevice that has a tiny channel in it, cut through a wee little capacitor, which blood will run through. As red blood cells pass this capacitor, the voltage will spike; meaning that for each voltage spike, we can (and are trying to) count the number of red blood cells.
However, I am still in the early developement of the program, so this above specific info is not that important. Basically, I am using a function generator to input a waveform to the DAQ assistant of, say 500 mV. I am trying to write a program that increments a counter every time I turn the voltage above say 550 mV (peak-to-peak), counting the number of simulated "spikes." I have tried quite a lot to write a working program, and although I have not gotten it to work yet, I will post a screenshot of my most recent attempt HERE:
I thank you in advance for any helpful tips, advice, or straight up assistance you may be able to give me. Please ask me any clarifying questions about the program I wrote or the application, or anything. Happy Friday!

Hey guys, it's been a while! A lot of stuff has been happening in my life and I have had virtually no time to work on my LabView project.
I did create a LabView program based off IanW's reccomendation. I am unsure of what exactly is going wrong, but when I run it, only a simple "snapshot" of a waveform from the DAQ shows up in the graph. Even when I put the DAQ assist in a seperate while loop, the same thing happens. I am including a screenshot of the project in case I am messing something entirely different up. If you happen to read this, I really appreciate your help and thank you Ian!
I am also having a random issue with the filter signal VI. So that background signals in the actual experiment do not read as "spikes" I have been instructed to include a high-pass filter in the VI. However, everytime I use the high pass filter VI, it botches my signal and turns it into a bunch of noise! I, nor my graduate mentor (who isn't too well-versed in LabView) have any idea why this is - we've tried using different types of filters to no avail.
Lastly, I would like to talk to Peter about a few questions I had abour LabView design. In case you're still around, I will write another post later today with more detail. In the meantime, I will try to find some of the example VIs about shift registers All who read this have a great day!

Help! Want to read from a xl file and get an output voltage value!!!

Hello..
I`m a beginner, so please help..
My program should output an voltage value that is read from an xl-file with one collum. The most important is that each values in the xl graph should be read per iteration. So that the file is read over time. I want to use this xl file to controll the output signal over time.
Can anyone show me how this VI would look like, and what would the xl file look like??

The easiest way to do this is to save your Excel file as a comma or tab separated text file and not the native Excel format. Then you can use Read From Spreadsheet File (on the File I/O palette). Using this, you can read the file all at once and then just have a 1D array that you can wire to a while or for loop so that with each iteration of the loop, you get one element in the array. A for loop automatically indexes an input array. Reading the file all at once will be more effecient that reading the file line by line.

Need help getting a voltage and current reading with myDAQ

I have set up a VI using the DAQ assistant with the myDAQ, I am using the ai0 port for a voltage reading and using the DMM for my current reading, the circuit is working as I am measuring the voltage on a resistor after the ammeter but I am unable to get a current reading in order for it to work. If I have something wired wrong please let me know, thank you. My circuit is a 12VAC power supply, going through a potentiometer to drop the voltage to 8VAC, which passes through a resistor, ammeter is in series after this and attached to another resistor to complete my loop, the AI0 for my volt meter is connected across the second resistor, I have the proper voltage reading when I run the VI, but am unable to get a current reading to display. Thanks for the help.

Mikes Project2.vi ‏134 KB

I mean I can't get a proper current reading as a numeric value, I have my power supply going to a potentiometer to change my voltage level and then have 2 resistors, I am measuring the current between the 2 resistors. By doing so I am getting a value but not the same value I am getting on my multimeter, I am also having trouble with the calculation using the formula R=V/I in my formula node. If I use input controls I can get the formula to work properly, as soon as I connect it to the outputs of what I am trying to read, the formula node doesn't work.

Help lowering the voltage

Hello all. I've came to this forum before, asking help to overclock my i5 3570K on my P67-GD65 motherboard. As I was running in to trouble with a game I rolled back my OC. Had it happily at stock for a while.
A few days I've turbo overclocked it to 4.1, not to shabby. The problem is, when at full load voltages are at 1.360. In my point of view, it to damn high!
I know that if I set the Vcore any other than AUTO I'll lose all power savings, and I don't want that... Could this value being so high because I have Vdroop set to High? On my BIOS I can only set it to High or Auto so I guess I don't have much to do
Can someone help me to reduce voltages so I can reduce temps also? While gaming (Skyrim, World of Tanks) tops out at 60º although I think it's a bit high with such conservative OC.
Disabled EIST, C1E, Spread Spectrum, EuP 2013, Overspeed Protection, C-State.
My relevant specifications:
Intel i5 3570K
MSI P67-GD65 (B3)
Corsair A50 with Be Quiet Shadow Wings
Corsair PC3-12800 1600Mhz Vengeance CL9 2x4GB

I have the latest bios also, as windows 8 x64.
Thanks.

Attached is E7681IMS.441 (Beta) you may try this bios if you wish, but there are no release notes pertaining to your issue. That does not however mean it will or won't help. If you want to test with this bios, >>Use the MSI HQ Forum USB flasher<<
Select option 1 and point the tool at the entire compressed archive (do not extract the attachment)
Point the tool at your fat32 formatted usb stick and then boot to that usb when the tool has completed its work.
Can I roll back to the stable one I have now if I have problems? Any chance of bricking the board with this beta?

Need VI design help, trying to output continuous voltage

This is one of my first attempts at this, so please bear with my elementary level questions.
I'm running LV 8.2.
Using the NI USB 6211 Multifunction I/O
My VI seems to work with the exception of a couple issues I'm not sure how to resolve.
1) I would like to turn on my voltage output (2v) on a true condition and have it stay on until the condition changes. When the condition changes to false, the output should turn off and stay off until the condition changes once again. Currently, when the loop is true the output turns on, but turns back off before the while loop iteration completes. So I end up with a on then off at the speed of the loop. How is this corrected??
2) I would like the indicator lamps on the front panel to be on only when the respective output is on.
Please have a look, any and all comments are appreciated.
Thanks in advance, Bryan

Hunley MR Damper Control.vi ‏933 KB

Thanks for the reply centerbolt,
I tried somthing like you proposed, only I used a mean value from the mathmatic functions pallet. This does change the output to a single floating point value. However, I still have the same palsing response.
Your correct, I am collecting a accelerometer value from a vehicle application. This measures roll acceleration. If the value is more than .2g it should activate the 2v output to fire a damper for the appropriate side of the vehicle and maintain the 2v until the condition changes. If the value is less than -.2, the other side damper should fire and stay on until the accel changes condition. But it doesn't maintain the output signal. Instead it cycles on then off every loop iteration.
I also have to figure out hoe to have my indicator light come on only if the respective damper is active.
Thanks again for any help, it is appreciated,
Bryan
Here's what I have at this point:

P55M-GD45 Vcore Voltage Help

I've read the sticky, I know about pg up/pg dn and the +/- keys.
My problem is that I can't manually set the vcore voltage in the Cell Menu. It says Auto (greyed out) and when I do pgup I can increase the voltage up to about +.303, but it doesn't allow me to manually set the voltage, nor undervolt it.
I've updated the BIOS to 1.8, but still no luck.
If anyone has any suggestions, please help.

Quote
I honestly wish the mobo had manual vcore control.
Well, it does. You said so yourself:
Quote
"Cpu Voltage" it is either Auto (Grey) or increasing the voltage in increments.
Quote
I didn't increase it +.303, I was only specifying the limit of what it would allow me to change.
To be honest, I fail to see the problem you are having with the voltage. That means that either I am terribly misunderstanding what you are trying to say or that you are misunderstanding the way the voltage settings work.
Can you please try to elaborate what exactly it is you are trying to do with the system? It is irrelevant at this point, what the system will be used for. What is of importance is what clock speeds you are trying to run the system with, what exact settings result in an unstable system and which settings have been working for you. Within a certain clock speed range from the default settings, increasing the core voltage of the processor may not even be necessary. It all depends on what you are actually aiming for.
In terms of current system settings, you have not really told us much so far:

Failed OCCT during a 2hr test.
Under what operating conditions? Base Clock Speed? Memory clock speed? Memory voltage? Memory timings (post CPU-Z screenshots [SPD & Memory]? CPU Voltage [as shown by CPU-Z]? Other Cell Menu Settings you modified? etc.

PS4 voltage, please help!

Hi, I just bought a PS4 in the States but I live in Israel, where the voltage is 220 instead of 110. I checked at the back of the PS4 to see if it would support 220V but it only says 120V, so I thought of using a voltage transoformer. However, in the instructions it says 'Do not connect the AC power cord to a voltage transformer for overseas travel because it may cause heat to build up in the system and may cause burs or malfunction.' What should I do?

Hi Samuel,
I hate to be the bearer of bad news, but as explained in this article on Sony's official PlayStation support site, PS4 consoles sold in the United States are only intended to be used in North America. Sony does not provide information on adapters or converters made to override territorial restrictions, and owners of U.S.-purchased consoles are not advised to travel with their PS4 outside of the United States.
That being said, I'd encourage you to follow up with Sony's technical support team when you have the chance to do so. While I cannot make any guarantees, they may be able to help you find a solution.

Need voltage help

my v core is set at 1.55
memory at 2.55
agp at 1.5
im not exactly sure what all of that is but...
with vcore right now its 1.07
3.3 is 3.04
5 is 4.95
12 is 11.96
so what exactly am i looking for when i overclock? i have a really cheap psu so i just want to make sure everything is where it should be when i OC

Don't look at tha numbers any software tool tells u. There inacurate.
2 voltages are usually raised when overclocking:
vMem, the memory voltage
vCore, the CPU core voltage
Raising the voltage will not make stuff faster.
Raising the FSB (HTT on AMD64 boards) or multiplier will make the CPU run faster. At some point it will become unstable, raising the vCore can help to make it stable again.
Same goes for memory timings and the vMem.
Raising voltage makes componts run hotter and wear faster, occasionally u may also blow soemting up if u raise the voltage too high

WEIRD RAM Voltage Problem. Really happy for some help =)

Hi I have a K8N Neo2 Platinum motherboard with BIOS version 1.4.
I have a wonderfull set of OCZ PC-3200 Platinum rev.2 RAM that preferably should have atleast 2.75 V. They do work with less, but stability can suffer in some cases.
My problem is that if I choose 2.75, 2.8 or 2.85 V in BIOS I still end up with 2.7 in Windows. Only by increasing the voltage in windows with, for example, Corecenter can I reach a voltage over 2.7. Why do I have this problem? Is there any simple way to fix it?
I mean, I think that if the MB was broken in any way (hardware wise) so shouldn't it be possible to change the voltage through windows (the voltages are correct BTW and the MB show no other signs of error except this).
Is this a know bug in any way for the MB or the 1.4 BIOS version? And as said before, do anyone know how to fix it?
Lots of thanks to anyone that can help (this problem is really making me confused).
Edit: one more question while Im at it. As many others I have freezing problems with my 6800 ultra. Is there any trick/BIOS that solves this (I know disable AGP fastwrites... helps and disable NV/Ati speed up... but except that).

The bug is most likely corecenter. It seems to report things wrong for most people. Try using speedfan or similar program to verify voltage before you get too concerned. Just dont use mbm 5, people have reported problems there as well. You can get speedfan at www.guru3d.com.

adjusting gtl ref. voltages isn't very difficult, but it is probably best to learn the basics first.
So, basically, increase the fsb a little. So, for example, from 1333 to 1400. See if it's stable, if it isn't try bumping up vcore one notch and try again. If not try Northbridge. Then later move on to stuff like the fsb term.
Test stability using prime95, there is a 64-bit multi-core aware version floating around somewhere. Try the ftp server linked to in the "hot use prime95" sticky on here.
Tbh with your OC you shouldn't need to touch any other voltages, or really use the gtl ref settings. What exactly is "sufficient" cooling though? Stock?
*EDIT: on a side note, just so you don't think I'm deliberately being awkward not telling you specific voltages, they wouldn't do you any good. Every cpu/mobo can handle different freq. at different voltages. Also, use cpu-z to check on your actual voltage and make sure you don't raise it beyond 1.3625 (I think that's right, it's 1.36something anyway)
Thanks for the tips. The reason I wanted to jump straight to FSB 1600 is because the MSI p7n is really picky and only likes 1:1 ratios.
My "sufficient cooling" is an aftermarket heatsink, high performance thermal paste, and MASSIVE airflow through my case. If you want specifics, its the Scythe Zipzang
Quote from: AaronYuri on 08-October-08, 09:05:16
CPU Voltage - No one can tell you this.
NB voltage - Depends on what frequency you want
SB voltage - What's your HDD setup?
NB Memory reference voltage - Auto
DIMM memory reference voltage - Auto
Memory terminator voltage - Auto
CPU GTL reference voltage - Depends on speed and other voltages
NB GTL reference voltage - Same as above
FSB terminator voltage - Depends on CPU voltage and CPU/FSB clock speed
SB sleep mode voltage - Auto
PCI Expander PLL voltage - Auto
My recommendation is do some reading. Guessing leads to dead hardware.
6GBs smells like mixing modules... Or do you have 3 modules?
First of all, I already stated the frequencies that I wanted in the top post, and fairly clearly at that.
CPU shouldnt be too hard to figure out, as there are very few to choose from. I'll try to get back to you on that one
I have 5, 7200rpm SATA 3.0 drives. It sometimes runs with only 4, as one is a hot swap.
My ram IS mixed, unfortunately. I'm using 2x 1gig sticks, and 2x 2gig sticks. However, both sets have heatsinks, and are rated at 800mhz, 4-4-4-12, 2t, timings. (2.1v)
I AM running them in dual channel.
If this helps you suggest voltages please do, If not, then I will just have to start trying using nihilkrist's suggestions.

Help.. Voltages !!
