    Sorry for the spelling mistake

    Hi dave



    the video card is stand alone (not onboard) fits onto an AGP slot on the board. I used to run 128 MB as 64 MB RAM ? why is it halfing?



    thanks

    Hi dave



    The previous video card was an S3 3D/2X Card, I replaced the processor with the same type of 400 mhz pentuim 2, the new card is an ATI Rage 128 MB , The halfing wasn't related to shared memory because the old card didn't say it was sharing in the bios



    Thanks

    Hi dave



    Its not the pc 133 ram or Pc 100 ram that is causing the ram problem cause I had a PC 133 ram in the pc and worked fine, I don't know what is going on. The CPU and fan is ok

    Roger,



    Sorry this is taking so long.

    This is one I'm having to RESEARCH on. Turns out this is a 1st Generation AGP board and I'm trying to narrow down the reasons for your symptoms.



    In order to figure this out I'm going to need to know the details of your upgrade. This Board can take both socket type and slot type CPU's.



    I need to know what you previous CPU was and what you replaced it with



    As well I need to know what Video card you HAD and what the new one is.



    The Memory issue (where the system only sees half) sounds like a shared memory problem with your video card but This is usually only with integrated Video cards, but I suppose if your old one was an OEM card(One made by ASUS it might still be able to share memory)



    Give me an update on the details and I will try to get you up and running again



    Thanks

    what is the specification for the RAM.?

  • David Preston
    David Preston May 11, 2010

    Roger,



    Was the video card you relaced an integrated(Built into the Motherboard) version?



    Or was it a standalone, Fits into the slot on your motherboard?



    Once I know this I can try to figure out why your computer is no longer detecting your ram.



    thanks

Roger,

The problem clearly isn't a video sharing as I was originally suspecting.
First let me inform you that even your upgrades are several generations behind the current mainstream, Not a problem as long as they are sufficient for your needs. I don't know about the CPU but the Video card is no longer supported by ATI.

Ok lets get down to the Nitty Gritty

First lets remove ALL of your cards from the PC
Video card, any PCI cards and if you have them even the ISA cards
Now remove the ram modules and the CPU

OK we should be starting with a bare Motherboard
Check to make sure that all of the power connections are attached in this case it should be a single 20 pin ATX connector

With that done make sure the IDE connectors are oriented properly there is a notch on the drives connectors that lines up with a key on the ribbon cable.

make sure this cable fully seats into the Motherboard and the drives connector(Try to route the cables so that they are tucked out of the way if possible)

Now repeat the procedure with the floppy drives ribbon cable and connector (If applicable)

Inspect the CPU make sure the heatsink and Fan are attached and mounted Flush to the CPU card
Now insert the CPU into the Slot1 making sure to pay attention to orientation. If I read right you replaced the processor with one of the same speed? if so you don't need to mess with the jumpers that are onboard for the CPU.

If it DOES need a different FSB setting the open up the user manual(Link below if you no longer have it) and find and set the appropriate settings

http://dlcdnet.asus.com/pub/ASUS/mb/slot1/via693/p2v-b/p2vb-102.pdf

attach the CPU fan leads to the proper header on the Motherboard

Now check out the RAM slots, there are 2 latches at either end of each slot. Don't put the ram in yet move the latches into an upright position. The should be firm in place you should NOT be able to wiggle them. If there is some PLAY in them we might have just found your ram problem. These latches sometimes jar a little bit up and thus PREVENT the ram modules from seating properly. Any latches that had some PLAY in them just give them a bit of downward pressure (Don't have to FORCE them) until you here and/or feel it click back into place. Now fold down the latches and insert the SDRAM cards once in place fold the latches up until they LOCK into place and hold the ram steady. If any SLOTs are empty fold their latches up too (There are little sensors under these latch arms, that if ANY are down it prevents the Rams address bus from energizing to protect any improperly seated modules)

Now insert your Video card, If there is a latch at the back of the AGP slot make sure that engages properly (Don't worry if there is not one SOME of the older ones didn't have them) just make sure the card seats down all the way into its slot.

Now install any other cards I had you previously remove from the system install any wires from the front panel header that might have been removed or jarred loose, make sure that your case fans are attached to their headers.

I think your ready to give it a try NOW.
When you boot up it may pause asking you to confirm a memory checksum error as the Memory level should be different from the LAST time it boot press what button is says to do so to continue. After the ASUS logo blinks off screen press <Delete> to enter BIOS make sure the Video card setting is for AGP and not PCI press <F10> to save and exit.

This SHOULD have you up and running if not comment back and I'll try to assist you further.

For your information the last Generation of Winows supported with drivers for this board are Me/NT/ and 2000

When you are next ready to upgrade I would recommend getting a more modern motherboard with integrated graphics (If cost is an issue at the time) It will improve your upgrade and support options

Hopefully this helps you
Dave

    OK you say your getting beeping when your trying it?



    pay Attention to the beeping its kind of like a Morse code specifically for PC's their called POST (Power On Self Test) codes if you can tell me WHAT the pattern is. I can narrow things down to what component is affected. It should be a pattern of short and long beeps.



    When you tell them to me use this format Long beep = L a short beep = S and a pause =



    so a pattern of 3 short 1 long and 3 short with pauses in between would look like the following.



    SSS L SSS



    looking forward to helping you further

    Roger,



    I searched for a bit to find THAT particular Beep code and found 2 possible answers.



    1.) Prob: One was that this beep code indicates a CPU fan error

    Solution: Double check the CPU fans connected to the Header just above and towards the left Side of the CPU's slot



    2.) Prob: Bad or improperly seatted RAM

    Solution: Try to reseat or replace you SDRAM modules (Verify you are using compatible modules) For you its simple If it isn't SDRAM PC100 then you've got the wrong RAM



    If these don't resolve your problem heres another way you can NARROW it down



    Replace your NEW CPU with your Old one if you get a different post code or if the machine boots up you KNOW the fan mounted to the NEW CPU is bad.



    Hope this helps you

    David Preston Nov 13, 2008

    Roger,



    I'm afraid you've stumped me on this one. You can try contacting Support at ASUS and see if they cant tell you what THAT particular POST/Beep code means.



    If your SURE that the 2 things I mentioned on my last post are fine, then my last best guess would be it has something to do with the Jumper settings that control the Processor Front side bus or the memory timings. (Information on adjusting those are in the manual which I gave you a link to previously)



    These settings are adjusted by jumpers on your board (So they have to be Physically changed) Whereas on more modern boards they are adjusted from within the BIOS or even sometimes automatically by the board itself.



    Good luck

    Dave

Hi,
As I figure your problem, it seems that you upgraded your motherboard, and video card, but the other part are still the same with your previous P2, if you upgrade your computer better to upgrade everything, cause if your still using the old part like the RAM, the upgraded computer will not detect that part.
Thanks.

ALL I GET IS A CONSTANT BEEP ON START UP. NO MESSAGES JUST FAST BEEP


It is common for most motherboards to beep to let you know
that something is not right: for example, missing/incompatible
RAM modules (or RAM modules not properly installed) or
missing Graphic Card or CPU improperly installed or overheating
beyond specs...If it's a new motherboard, lay it out outside the
case, installed with the minimum one RAM module, a Graphic Card
(if no built-in Video), the keyboard and mouse. Plug in the power
supply and CPU power coonectors and make sure you can post it
without any error. If there are, check your CPU and its socket, check
for thermal grease. Check for properply installed RAM module. Check
for Graphic Card if any. Of course, assuming that all your components
are compatible with your motherboard (consult user's manual or
manufacturer's website)

Hi, I need standard spec info of VGA built on Asus P5GC-MX 1333 whether 64 Mb or 128 Mb. Many thanks & regards, Richard


you can use up to a maximum of 224 mb of your computer's RAM for the onboard video chip to use. You can install a video card with any amount of memory (which would give you a lot better video performance).

My dv6-1247 cl when i turn on the power it beep 8 times and the screen does not come on help


Yu will need to determine which BIOS you have a see below
The computer beeps several times
If you hear several beeps from the PC speaker, it means that the computer failed its power-on self test (POST) because a problem was detected. The POST is a procedure that tests several components such as power, BIOS, CPU, memory, and video. Only if all those tests pass, the computer will then allow the operating system to load. But if one or more of these tests fail, beeps indicate a problem and the boot process is halted. These errors are a little more difficult to troubleshoot.
To diagnose the problem, listen to the beeps carefully and write down the sequence. Is it one long beep? Is it several short beeps? How many? Once you have the beep sequence documented, you need to find out what it means. What BIOS do you have? When you first turn on the PC, look at the top of the first screen to find out. Common BIOS types are Award, Phoenix, and AMI.
Award:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information Any other beeps Most likely a RAM problemYou can find more detailed information about Award error messages on Award's web site.
Phoenix:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information 1-2-2-3 BIOS ROM Checksum 1-3-1-1 Test DRAM Refresh 1-3-1-3 Test Keyboard Controller 1-3-4-1 RAM Failure 1-3-4-3 RAM Failure 2-1-2-3 Check ROM Copyright Notice 2-2-3-1 Test for unexpected interrupts 1-3-4-3 RAM FailureYou can find more detailed information about Phoenix error messages on Phoenix's web site.
AMI:
1 beep Refresh failure 2 beeps Parity error 3 beeps Base 64K memory failure 4 beeps Timer not operational 5 beeps Processor error 6 beeps 8042 - gate A20 failure 7 beeps Processor exception interrupt error 8 beeps Display memory read/write failure 9 beeps ROM checksum error 10 beeps CMOS shutdown register read/write error 11 beeps Cache memory badYou can find more detailed information about AMI error messages on AMI's web site.
If you get beep errors, you should try to think what happened right before they started. Did you add a new piece of hardware? If so, it might be faulty or not installed right. Remove it, then try again. If everything is fine without the hardware, try to reinstall and configure the hardware again. If that does not help, try exchanging it and see if that corrects the problem. If the error persists, narrow it down systematically. Remove everything but the CPU, memory, keyboard, and video card, then boot again. Does the error still occur? If not, then add one piece of hardware and try again. Repeat until one new component causes the error and you now know who the culprit is. If yes, then reseat your CPU, memory and video card and try again. If the error still happens, try replacing the CPU, video card and memory one by one to see if one of them is the troublemaker. If that does not help, you could have a bad motherboard. Check the motherboard carefully for any signs of damage. Also check for shorts, a metallic object could have found its way onto the motherboard, or the motherboard is not installed correctly and touches the case somewhere.

DDR2 Ram allergic problem....


When using different kinds of RAM together in the same computer, there is a general rule that the Slowest Ram has to occupy the first slots (the ones closest to the CPU and usually numbered on the Motherboard)

This is possibly the cause of your ram error although they're both 400Mhz, just try re-arranging them.
I think the Ram Error Code is two long beeps and the video error is one long beep and three short beeps.

Also, watch the Ram counter when you first turn the computer on, or check the "My Computer" properties to see that all the RAM installed is recognized.

New Motherboard Problem


I believe you have a driver conflict
Check your BIOS is set for CPU etc.
And Uninstall all drivers And see if computer start with only the windows drivers present.
As if you have just installed windows and no M/board drivers.
And reinstall M/board drivers one at a time Should fix your problem

Got video now


Memory banks 1 & 2 are where your computer looks for RAM. If nothing is installed in them then the computer looks no further. You can upgrade RAM by putting 2 more sticks in the unused banks as long as they are compatible to the board and first 2 sticks. It makes no sense to buy faster than the first 2 as the cpu would make them run at the lowest speed of all installed RAM. If you are using an asus board then when you boot up you should be able to press the del key to enter bios setup. Video cards are more to preference. If you have the psu & board capabilities then the sky is the limit. Hope this helps & please remember to rate my answer. Thanks.

Upgrade P5RD1-VM motherboard to the gaming PC


Your pc is not for gaming right now because you are using Intel Pentuim 4 Mother board and CPU. Amd Athlon is best for gaming. I have a AMD Athlon 4200+ X2 with 4gb Ram and Nvidia 6800 256mb OC. to upgrade your computer to a gaming pc. you will need to switch your motherboard and cpu for best performance on games. in order to do that, you might need a different case for your new motherboard. because the one you have might not be right for the AMD Athlon motherboard unless you have a custom made computer. other than that everything is set for you. if you have less than 1gb ram you might want to add more. because the games they are coming with right now is 1gb minimum or required.

i hope that answers your question.
