ATI AGP Voltage Problems

I use the ATI AGP card ! It is  R9100(GPU) 64MB DDR  Series !
who have experience in ATI cards ?
My AGP card is working at  1.5v !  Who know at  which  voltage it will be  perfect performance?  
r9100 GPU Core at 250Mhz ;DDR Also at 250Mhz  !  support DirectX 8.1
How to overclock my ATI card?

Many people thought that AGP 1.5V ~ 1.7V is the one use to overvolt your AGP card. But in fact, that is little to do with AGP card. It has more to do with the AGP signals, and much much more to OVERVOLT and OVERHEAT your board chipsets - MCH and ICH (northbridge and southbridge)!!!
If you plan to overclock your whole system, you need to adjust this 1.5V higher, 1.6V which is OK. If your system crashed, it's not only to be your AGP card causing the crash, but also the onboard chipset!!! However, Intel chipset is very very robust by its own so it ends up to the motherboard design quality and also AGP card design quality.
Furthermore, now most high-end AGP cards have their own voltage supply by external power connectors. Some cards even have their own 1.5V regulator. So the AGP 1.5V does very little here to these AGP cards.
In answer to mofamous, stick with 1.5V, it's not necessary to overvolt it even you overclock your card. There is little performance margin you can gain from overclocking your card. And plain voltage pumping will not help much too.

  • MS-7025 AGP Voltage Problem

    I just tried to upgrade my video card and the new card wouldn't work.
    The computer store said I may need to increase my AGP voltage.
    The card I'm running now is a nVidia 5900GT and I tried a nVidia 6200. The 6200 wouldn't work..
    Can anybody explain what I need to do? I'm comfortable with BIOS changes.
    Thanks,
    Bill

  • Kt4v (ms-6712) agp volt problems

    Hi, i have an problem with my kt4v and my ati9800 pro. When i play games who need lots of power (pixel shader2 ect) like farcry. Ati's vpu recovery kicks in about 30 minuts and either it will fix it or i need to reboot when it fixes it the first time the next crash will take place again about 30 min later. I did a lot of rechearch about this problem and i think the solution is to increase the agp voltage to 1.6 or 1.7 but my pc wil lockup after 2 minutes when i put it on 1.6 and when i set it to 1.7 it will boot but i cant see my mouse and get all kind of glichtes.
    I already bought a new power supply (420 watt) my power stream is according to pc health: [email protected] - [email protected] - [email protected] - [email protected] there all dropping and resing slithly all the time.
    Any one know a fix?? i would be very gratefull

    That seems to be a common occurance with this board and ATI video cards, actually many boards and AGP 8X video cards. It seems the AGP 8X spec is still not fully optimised, or is still in need of refining. The good news is, there is less than 1% difference in performance between 4X & 8X. The AGP bus is pretty much capped at 4X, and 8X just cannot deliver a noticable improvement. I seriously doubt there will ever be a fix for this situation, as PCI Express is the direction all newer motherboards and video cards are taking to improve performance.
    I think the problem lies in the lower voltage for 8X, as the frequency is raised, the voltage has to be lowered to reduce heat buildup, and the lower voltage just cannot run the video in a stabil manner.

  • NEO 2 AGP fastwrite problem

    Hi all can anyone help me!!
    SPEC
    MSI neo2 platinum Bios 1.8
    AMD A64 3500+ 939
    Tagan 480W PSU
    2 X WD SATA 80 GB harddrive (Raid 0)
    Gainwad 6800 Ultra
    Creativ Audigy2 ZS Plat
    1GB OCZ platinum Rev2 DDR memory
    Sony DVD-RW
    Sony FDD
    MSI CD-ROM
    Windows XP SP2
    Iv had problem with this board ever since i brought it around 8 months ago and am starting to lose confidence in MSI products
    The system is now 100% stable at last
    But when i run games with anything newer than nivdia 71-24 drivers, the games freeze every 5 or so secs and wont run correctly. This is caused by AGP fastwrites not working with newer drivers.
    But if i increase or decrease the graphics card clock by a few Mhz's the games run perfect with new drivers and fastwrites enabled. but if i do something quick in a game i.e when BF2 loads a map if i click start imedietly the game freezes every few seconds
    I have tried disabling fastwrites but i notice a very big decrease in performance and the game freezes every 10 mis or so
    Is there a fix to the problem or have i got to rip out this motherboard and never buy MSI produtcs again    
    Thanks in advance 

    Berno,
    Keep smiling and do not give up, you are smart and can resolve this issue. Nvidia video cards are quite good when use on the Neo2 plats but they do like definite settings.
    1- First insure that your video card is set at stock speed and neither its FSB or memory speed are overclocked.
    2- Go to BIOS Cell menu & look up "Adjust AGP frequency" set this option to "67" this will lock your AGP bus speed.
    3- Then do following while in main BIOS Cell menu:
    a. Press "Shift + F2" and then "ALT + F3" this will unhide three previously hidden BIOS 1.8 Options (NV/ATI Speed UP; DRAM Drive Strength, and PCI Clock Auto detect) Live last 2 alone
    b. Set NV/ATI Speed UP to AUTO or live it there if already selected.
    4- Save and Exit BIOS and reboot. Try out new VGA card driver + games and see what happens
    5- Post again if still having problems
    Remember that if you decide to OC your Video card you must set BIOS as follow:
    1- AGP fast write - disabled
    2- NV/ATI Speed UP - disabled
    3- AGP adjust Frequency - 67
    You may also need to adjust your AGP voltage in Cell menu upwards by up 0.5 to 1.0 volt to stabilize Video card when OCing GPU or video memory. Monitor GPU temp closely if you do so.
    Good look and remember to keep smiling, you can and shall overcome...

  • MSI NX7600GS AGP direct3d problem

    hallo,
    recently i replaced my MSI GF4ti4200 (128MB) with the NX7600GS
    i did a lot of testing already so i've tried to make an overview
    (i've tested OpenGL with Doom3 and Direct3D with 3Dmark2001,2003,2005)
    in al my test situations, 2D works perfect
    i have an older motherboard (VIA KT133)
    AGP4x mode with Fast Writes
    - OpenGL = crash when entering 3D mode
    - Direct3D = crash when entering 3D mode
    AGP4x mode without Fast Writes
    - OpenGL = crash when entering 3D mode
    - Direct3D = works, but heavy graphic corruption (clipping errors, texture errors)
    AGP2x mode with/without Fast Writes
    - OpenGL = works perfect
    - Direct3D = works, but very heavy graphic corruption (clipping errors, texture errors)
    so i guess my motherboards AGP port isn't that good (although the GF4 always ran very stable at AGP4x with FW)
    because it doesn't make lots of difference i do not care about AGP2x or 4x, but i get the feeling Direct3D seems to do better in AGP4x mode
    i already tested the VIA drivers for my motherboard (old and new ones) and various nVidia drivers (there were a lot on the MSI install cd, but few of them work with a 7600)
    the card is OK cause i got it to run perfect in Windows2000 in AGP4x mode, but then i installed WindowsXP...
    (i already reinstalled Windows2000, but i did not get to run anymore cause for some reason)
    Some cards change frequency's when entering 3Dmode, does this card do that too? and how can is disable this (some people say this causes problems on older motherboards)
    any suggestion is welcome

    not all agp4x mobos can handle agp8x vga... i had experienced that.
    i didn't know if that vga has extra power conector, if not maybe the mobo cant give enough power to the vga.
    if there is an extra power connector then must be attached, and the psu is important, not only the wattage, but the amp on each rail. so post detailed specs of your psu. good look
    yep catfishjvl folow ivangelion advice and paste PSU details which i has been asked before.
    agreed, there is 3-4 simular cases with old VIA chipset board and simular problem. all is unresolved for now.
    catfishjvl you can try to push AGP voltage to 1.6V may help. and retest. but dont go more than 1.6V

  • Agp voltage

    hi,
    i have a asus radeon 9800xt/tvd and every now and then i get weird thick dark bands running vertically at window xp pro desktop...also has narrower horizonntal banding as well.  I reboot and it generally works after that properly.  However, the other day it initialised the GART driver just before desktop loading and suddenly rebooted...then did it again.  I went to bios and increased agp voltage from default 1.65v to 1.7v and it worked.  Hssn't done anything wrong since.  Was i right in assuming that was the problem and can i damage the card by doing so?  Has this happened to anyone else?  If so, how did you solve it and what was the cause?
    Aspro
    p.s. using latest catalyst drivers.
    p.p.s. does anyone use the asus enhanced driver for their 9800xt/tvd instead of catalyst?  if so why?

    I have read about some people using 1.7v to solve certain problems although this was earlier 9600 cards I believe. I'm pretty sure you can't damge anything with that setting so if it works keep it. It is odd though that increasing voltage would solve this since the card gets most of its power from the extra cable you connected.

  • PT 880 & Radeon 9800 pro - heavy AGP Voltage

    Hello!
    I'm worrying for my AGP voltage witch is 1,75 V (in red in core Center).
    I cannot change it in Core Center though (OK- and save) because after
    reboot it goes back to 1,75 V. My two friends who got similar computers
    have the same problem. The difference is that I've Sapphire's and they
    have Club 3D's graphic cards.  
    What to do - any ideas?
    Regards
    Lars

    Hello!
    After spending some hours reading around in this forum I've realized
    that Core Center isn't that good. I'll certainly remove it. I've had some
    problems with hang-ups on my computer but my friends haven't experience
    this yet. I thought it was due to old drivers but realized it probably caused by
    Core Center. Thank god for this forum and all you guys with answers.
    Regards

  • K8N FSR AGP voltage too high w 6800GT?

    Hi guys !
    I've been having trouble oc:ing my 6800GT and one guy told me that the problem is related to my AGP voltage. It's too high thus preventing the GT from running normally at higher speeds.
    The symptoms of oc:ing are 1-3 sec freezings in 3DMark05/03/01 plus crashes "expolrer.exe & drwtsn32.exe". It's not a heat-related problem because I have a NV Silencer 5 mounted on the core which also covers all mem chips. My temp indicator shows me 45-50C idle 60-65C full-load.
    I've heard that the GT requires 1.3V AGP voltage. Unfortunately you cannot lower AGP voltage in BIOS.
    Any suggestions ??

    i have almost teh same setup.  when i first got my 6800 i had same issueso/c and i watercool.
    it wasnt until i swapped my 430true power to wifes 350 enermax that it was straightened out.  ex has like 32a on 12v line
    cpu used to use the 5v line but now almost your whole system rides the 12v line all peripheral cpu and your gt juce sucker.  so those old powersupplies cant keep up with big systems like ours
    also with a64 some games you need to turn cool and quiet off during because the way the code is written it doesnt keep cpu at 100% so the cpu keeps throttling down and up.  i just shortcut in my toolbar for the power control from control panel. it works nicely
    agp 1.5v.  6800gt core voltage is 1.3 ultra is 1.4.
    those numbers are not really related.  your friend may be connecting numbers which are not related.  dont forget 6800 has its whole own mobo essentially with a core and ram and other chips sitting on it. thats what the agp 1.5v goes to.
    hope this helps

  • Why would you have to raise AGP voltage

    I have an MSI 6600GT and I was wondering when would you have to raise AGP voltage? Can you safely and stably overclock the card without raising AGP voltage? Is there a way to monitor GPU temperatures? What are safe temperatures?

    why would you have to raise AGP voltage
    you dont normally have to
    though in the case of some ati cards they are not happy without it upped a bit
    but ive never messed with it an any nvidia card myself

  • MSI 645 Ultra-C AGP voltage?

    Would like to know what is the AGP voltage of the motherboard mentioned above, can't find it anywhere in the MSI site.
    Asking because I'm using that mobo, and my newly bought ATI radeon 9600xt just won't work on it. When I say it won't work, I mean it crashes at any attempt to do 3d rendering(including direct3d test at dxdiag). My older card GF2MX worked pretty well.
    Someone suggested that "cause new graphic cards are using 1.5V......... Old 4X AGP are only compatible with 3V graphic card. " How true is that? Could that be precisely just why my new graphic card won't work on my mobo? The board I mentioned above only support 4xagp true enough, but I'm not sure of the voltage. Does anyone know? The manual does not specify it.
    Yeap, I installed and updated to the latest drivers.
    Thank you!

    My mobo can support 4x/8x AGP but I did use older AGP cards on it so no worries. I used to have an SIS 645D SA7 mobo from Abit that runs 2x/4x AGP Gart but also supports 4x/8x AGP cards as well as 1x/2x & 2x/4x AGP cards since 4x are found in all current AGP cards and on almost the new AGP cards, the RAMDACs are running on 1.5v(including the older GF4 series) so it's definately supported.
    Just follow my suggestions on increasing your AGP Voltage for your ATI card in BIOS and use Omega drivers for ATI based AGP card. It won't harm your ATI card at all .
    Lastly,I recommend that you do a clean un-installation of your old nVidia drivers or any older versions of AGP drivers before installing the new drivers. You may also be required to update your AGP Accelerator Gart driver for SIS based mobo, check the mobo's driver page for the latest version .

  • AGP Voltage @ 8x

    Hi
    I have query regarding the voltage that my GeForce FX5200 AGP card should be set to in the BIOS.  
    The 'spec' for the 875P AGP 3.0 slot states:
    "AGP slot supports 8x/4x at 0.8v (AGP 3.0) or 4x at 1.5v (3.3v is not supported)"
    Now according to CPU-Z, my FX5200 is running at 8x and my voltage setting is 1.65v, but shouldn't it be set to 0.8v for 8x?  
    (Come to think of it, I don't think the AGP voltage goes as low as 0.8v because I bleive the minimum voltage is 1.55)?
    Maybe I'm not reading this correctly but I don't want to damage my board or AGP card, so I'd rather check it out with you guys.
    Regards
    Brave01Heart

    No 1.55 is Fine ...As that is what MSI chose to use as the AGP Default......Some people run it at 1.6, But as most people don't realize that these newer generation Vid Cards get 90% of thier operating power from the +12V line (of the 4 pin Molex connector)....And even if you dont have a four pin molex, the only thing that you are doing is heating up your MCH (north bridge) with the the extra juice if you run it more then 1.5 Volts .....Sean REILLY875

  • MSI FX5200-T128[8917]Has 5200Ultra Chip Will it need AGP Voltage rise

    Hi,
    Some where in this forum i saw that someone is talking about after removing the heatsink of 5200 and seeing it is 5200 Ultra ...It happened to me too...  
    My GPU is ought to be 5200 but under the heatsink it is 5200 Ultra
    soo i need help about that how can i found vga bios for to turn its bios to 5200 Ultra's  
    My xp drivers saying it is 5200, after i updated bios will it be turn to 5200 Ultra...?? it must be but is there any compability issues known by anyone ??
    And it is 5200 Ultra why it doesn't needs external power input[From PSU] like other Ultras have ?
    If i rise the AGP voltage will it be helpful to use all power of 5200Ultra ?
    thanx for your time ...
    Sorry for my english

    Since this issue is regarding a VGA card I'm moving your thread to the VGA Forum...

  • Agp voltage --- 1.6v ???

    guys,
    i have an msi nx6800gt and my mobo is msi k8n neo2 platinum.
    do you think i should try using 1.6v agp voltage?
    i'm currently using default 1.5v but i was just wondering if using
    1.6v would help me o/c a bit more.
    at the moment the card doesn't o/c well at all.
    would it be safe to use 1.6v?
    thanx

    Yes, 1.6v is safe, but it may not help you OC much higher. If the card won't OC very well it's either to hot or your PSU is to weak on the 12v rail...Or you just got a card that doesn't OC well, that can happen too...Good Luck.

  • AGP voltage of gpu MS8808 ver:1A TNT2 Model64 32Mb??

    I need to know the AGP voltage of gpu MS8808 ver:1A TNT2 Model64 32Mb
    because I am getting a new Motherboard and it seems it just admit 1.5 volts AGP Voltage.
    Thanks

    That is a 4x Vid Card. All 4x and 8x vid cards work with 8x mobos. All 4x and 8x mobos work with all 8X vid cards.
    Here is an 8x Vid Card:
    Take Care,
    Richard
    P.S. If the card does not fit the AGP Slot on the mobo, the voltage is wrong. (The only time this is not true is with some old Vodoo Cards that were put on the wrong PCBs.)
