Question about ATI RADEON X1650 Xt, (256 MB) Graphic Card

1 Answer

Crazy x1650 Overheating may be the problem , but dust cant be a negative factor ( the graph card has 1 month ...it has no trace of dust anywhere ) ...so i think that 'cause of overheating the GPU is dead ? ...if i start my computer with this card after 3 minutes the whole PC hangs up..and on the monitor i can see a lot of weird things (lines, triangles , dots ) of different colors....so what do i do with it if the GPU is the prob ? reply me soon please...10x , again

I have had similar problems with graphic cards, and in most case i had to replace the VGA card. A technician i know gave me a temporary solution (though he had no idea why it sorted the problem up), where he would take his hot soldering iron over any place where there were solder points (not touch but over it so that they got heated up).

Once this was done the VGA card actually worked for a while (2 more months before the problems came back). I tried the same with my home soldering iron (which was not as powerful as the unit used by the technician which said 400C!) and this only solved the problem for a few hours! So basically you need a powerful soldering iron.

Another factor i have heard is that if your power supply is not good, the graphic card struggles to work properly and fails after a while. The X1650 is no power hog like the some of the higher end solutions, but in case you have a generic power supply saying 300-400W this could be another cause for your problem.

Graphs are drawn as the negative


There is nothing mysterious about it. Wittingly or not, you
switched the window limits.
Examples
Xmin=6.3, Xmax=-6.3
Ymin=3, Ymax=-3
or some other combinations.
Here is the 1st case (Xmin=6.3, Xmax=-6.3, Ymin=-3, Ymax=3).
The traced point has positive x

Complete switch. The graph looks correct but as
you can see the traced point has positive x,
and negative y.

I made a scatter graph with a linear regression and now want to find values for points on the graph that are not my original plotted points ie if X is 50 what is Y or if Y is 5 what is X where these were...


Your question is a very interesting one and I believe people will benefit from a complete solution to it. So I will provide a solution but I will apply it to a quadratic regression.
The points I will represent are those on a parabola
L1= {0,1,2,3,4,5,6,7,8,9,10}
L2={0,1,4,9,16,25,36,49,64,81,100}
As you can see, I am cheating (no experimental points will fit a perfect parabola) but this will have no incidence on what I am going to show you.

1. PREPARE THE GRAPH FORMAT (you will see why latter)
With the calculator turned On, press [2nd][ZOOM] to access the (FORMAT) screen. Notice that RectGC is highlighted. It means that the coordinates are rectangular. IF the POLARGC had been highlighted and you had used the TRACE function the values of the coordinates of the points being traced would be in the form (R, theta), in other words polar coordinates.

2. ENTER THE DATA

Press STAT, then under the EDIT menu press [1:Edit]
57b097c.jpg
to open the list editing screen. Enter the elements of the two lists
d10bb96.jpg
After you enter the data in L1 and L1, Press [2nd][Y=] to open the (STAT PLOT)

3. CONFIGURE THE STAT PLOT TYPE

Initially the Plot1 may be OFF. Make sure at the beginning that all Stat Plots are OFF. If necessary press [4:PlotsOff] execute the command in Main calculator screen and press [2nd][Y=1] to get back at the stat plot screen configuration below
d653a12.jpg
Press 1:Plot1 Off to open the P1 configuration
The cursor will be blinking on On. If not use cursor to highlight ON and press [ENTER]. The cursor will move to second line (TYPE), on first icon. Since you want to do a scatter PLOT that is the one to choose. Highlight it and press ENTER then move cursor with Down arrow to move to XList
If your data is in L1 and L2 Xlist and Ylist will be already selected. If you have entered your data in some other lists, enter the proper lists (L3,L4, etc.)

DRAWING THE SCATTER PLOT

Now you can press the [GRAPH] function key. Here is what you get
0d9dbd0.jpg

PERFORMING A REGRESSION

Because I chose it so, we will perform a quadratic regression QuadReg
To do so you press [STAT] and use right arrow to select the CALC(ulate) Menu. Type 5:QuadReg

b12881c.jpga7fbc6b.jpg
Command echoes on Main screen as QuadReg with blinking cursor as above on the right.

If you press [ENTER] the calculator will assign L1 to X and L2 to Y by default. If that does not correspond to the problem, you had better change the names of the lists used by entering then explicitely on the command line. Just press [2nd][L1] then [2nd] [L2] to get the following screen
30d1079.jpg
Pressing [ENTER] to execute the command will get you the regression equation and its coefficients but you will not be able to have it graphed on the scatter plot

2757d7c.jpg
The coefficient/factor of determination R2 is displayed if you ran the DiagnosticOn command from the catalaog, or as in the newer version of the OS (version 2.53MP) you press [MODE], scroll down to get to the second page of options and selected Stat Diagnostics ON

e380d1f.jpg
Thus to be able to draw the regression curve on the scatter plot, you must save it to a function variable, Y1 for example. You do it with the following command line
0b6bc57.jpg
After you press ENTER you obtain the equation, a,b,c, and R2. By pressing the [GRAPH] function key you get the raw data and the regression on the same screen.

3e957b3.jpg
As you can see both are represented

TRACING THE REGRESSION CURVE (Sorry it took so long to arrive to the point)
Press Trace and see what you get
e481e00.jpg

As you can see the trace defaults to the scatter plot P1, L1,L2 (see the top left). If you stay on that graph you will on ly trace the actual data points (raw data). The cursor will jump from one point to the next.
To trace the regression curve (the second curve) you must move cursor on it. To do so press the Up and Down arrows. Left and right arrows allow cursor to move along the same curve.
Pressing Down Arrow you move to the regression curve. Notice the equation on the top left corner. The cursor can be displaced anywhere (depending on the resolution of the graph.

Can i solve an equation of second degree(like X^2+2X+1) with Casio FX-7400G Plus ? If so how?


Sorry but the calculator does not have a solving routine. You can however use the graphing capabilities of the Casio FX-7400GPLUS to solve an equation f(X)=0.
  1. Graph the function Y=f(X)
  2. Use the trace function to locate the point(s) where the function vanishes (has value Zero)
See the screen capture for an example.

If you were hoping that this calculator would be able to factorize polynomials for your, sorry my friend it cannot.

Monitor stays black. Says no video.


I'd try running windows in safe mode by holding down f8 at startup. If that ends up working it's probably a setting that is wrong. If all still remains black i'd look at testing another video card and monitor. Either one could be it.

Hello matbedui,
If you think the Radeon card is overheating you can check this by simply touching the card after it's been running for sometime. Some Radeon cards (high end) do have this problem. PC cases that do not have sufficient fresh air flow cause problems not just to video cards but to everything inside the case. The design of the HIS Radeon X1650 is less than sufficient. Keeping air flow contained. One way in & one way out. This issue is so important many companies creat sites to help you cool your card.

Your Radeon X1650 Pro IceQ II runs ATI's chips. Installing the latest software is recomended. Download from here:
http://ati.amd.com/support/driver.html
Pick your OS. Than pick Radeon. Scroll down to your X1600 series. You can also update through HIS. Their software is twice the size of the ATI software.

Ati Radeon X1650 goes mad ....


Eeek its the card getting too hot and thus causing the wierd lines , due to dust build up , remove card & connectors , take off the heat sink , remove old thermal paste & apply new thermal paste (if necessary needs to be replaced if it looks dry and cracked) and remove the dust around it using a brush or compressed air.

Why do you think so?
Does it boot in Safe Mode?
Remove and re-seat this card, then reinstall the drivers.
