My Ti4800 set at agp 2x

ok kids i need ur help, i'm using a MSI G-Force 4 Ti4800SE on my ASUS CU4X mobo and WinXP Pro.
I set agp 4x on da mobo's BIOS but when i checked on da ge-force tab in da display properties, da card was on agp2x and couldn't be changed.Plz help me ok thx!

That mobo chipset is the old Apollo Pro 133A. Asus had problems with the GART Driver and disabled a lot of the AGP Features.
Make sure you load the latest GART Drivers.
Go to Viaarena for the latest 4 in 1 drivers.

FSB spread spectrum setting and AGP spread spectrum setting on K7n2G-I

For the combo K7n2G-ILSR and athalon xp 2400 what would be the best setting for the FSB spread spectrum: disabled, 50%, or 1%. and for the AGP spread spectrum: disabled, 50%. does it make a diff.? Can I leave them set at disabled even though I do not plan on overclocking? Anyone know? Does this affect video output(i dont think so) Thanks for any help-

Yes, leave them both disabled.

Is there a definitive word on how high/low to set agp aperture, et al?

Seemingly, the most elusive part of the bios settings is the agp-related settings (agp aperture, fast-write, etc.). I say this, because all I ever find on posts is 'this is what I do', or 'well, this is my rule-of-thumb...'. Is there no definitive logic for how to set these? I realize, like some people say, you can futz with the settings, run a benchmark, rinse, repeat, until you get your best benchmark setting, but this seems a bit too 'random' for my taste. I'd actually like to understand what I'm doing, why I'm doing it, and be able to see the benchmark to prove it right or wrong.
Does anyone have a good, definitive understanding of these features to be able to offer a reasonable justification for setting them one way or the other? So far, in my limited understanding, I tend to think I should set my agp aperture to as low a setting as possible, for example, as my video card has 256mb onboard, which exceeds the requirements of the games I play in-and-of-itself. Thus, why would I want to tie up system ram when video card ought to have more than enough already? Maybe this sounds stupid, but that's why I'm asking

256Mb should be more than enough to run todays games at HI settings. From what I understand it only addresses out memory tasks when onboard memory has exceeded its amount. Running down the AGP bus to RAM would be slower than onboard because of the interface (GFX-upto 256Bit DDR3 etc). If the app can run happy with onboard RAM, the amount set for "aperture" is used for system use and is not set a side until the apps needs more than GFX can offer addressed onboard. It does need an amount set even if its the smallest amount. I thinks

AGP Aperture.. What is it and where should it be set?

While messing with my new MSI video card today I came upon a good question.. what should my AGP Aperture be set at for best performance? Is it based on amount of system memory? Video card memory?
To refresh your memory I have:
AMD XP 1600 Processor
512 DDR RAM (2x256)
MSI Geforce4 ti4200 64MB 8X
Asus A7A266 Motherboard
30 GB Hard drive
Thanks!

(long post warning)
You've all got a pretty good understanding.
VGA memory on your card is used as required by the application FIRST (for textures, buffers, code, etc.). Key point - VGA memory is FAST - remember, in the case of a G4Ti4600AGP it's clocked at ~650MHz(DDR). (and in the case of the GeForce 5600FX, that's now 1GHz DDR II)...
AGP Aperature memory is used NEXT (for textures) if your VGA memory is full and the application requires more. The amount of memory available is as you set in the AGP Aperature setting in the BIOS.
The key point about AGP Aperature memory is that it is the portion of your _SYSTEM MEMORY_ that _can_ be allocated to be used as AGP memory IF required.
What's special about it, is that any access made to it (by the Video card) is done directly through the AGP bus without need for translation (i.e. without CPU intervention) - this makes using the aperature memory faster than using normal system memory. (but still much slower than the local VGA memory as seen above - eg. a P4 can use 400MHz DDR RAM - much slower than the VGA memory not even accounting for latency, AGP bus speed, etc.).
Finally, if after this your AGP Aperature memory becomes full, then the application must resort to using regular system memory - requiring CPU/Memory Controller intervention - and share with other components (PCI bus) also requiring access to the system memory. MUCH slower.
Setting a large AGP Aperature won't hurt you as it's only going to be used if your VGA memory is full - however, once used, it's taking away from your system memory. So, if you set your Aperature to 128MB and you only have a total of 128MB system memory installed....
If your VGA card has alot of memory (64MB or 128MB by today's requirements), then it's likely you won't need a large AGP Aperature as the VGA memory will handle the load. Still, suggested requirements is to set your AGP Aperature at either 64MB or 128MB (and if you've got the system memory to spare, than all the more power to you). If OTOH, you've got a small amount of system memory, you may want to remain conservative here - but it will still also depend upon the amount of VGA memory you've got.
Eg: in 3DMark 2000, there was the 64MB texture test - anyone running a 16MB VGA card with an AGP Aperature of 32MB could not run this test - even setting the Aperature to 64MB didn't necessarily mean you could run the test due to overhead - from the link I posted above:
Quote
AGP aperture must be more than twice the size of the desired AGP memory space. So, if you want 15MB of AGP memory for texture storage purposes, then the AGP aperture has to be at least 42MB in size.
The good news is that games today don't yet require this massive amount of memory, thanks in part to texture compression techniques, etc. - but who knows what the future holds (hence we're seeing cards with 128MB and now 256MB on board). A few more years down the line, and the technology will probably change altogether (I've already heard of the AGP bus being replaced).
(whew...I hope everyone understands better. This is at least my understanding of AGP Aperature - it might not be 100% accurate)

Problem setting AGP 8x

Specs:
MSI KT4V w/VIA 4in1 4.51 and AGP 8x
9700 Pro 128mb w/ Cat 4.3
Bios 1.9
Win 2kPro
Dx 9.0b
I looked at the FAQ for my board and it says that AGP 8x will be automatically set if available. In the bios, I cannot manually change the AGP Timing setting. When I ran dxdiag, I noticed the following:
Display Devices
Card name: RADEON 9700 PRO
Manufacturer: ATI Technologies Inc.
Chip type: RADEON 9700 AGP (0x4E44)
Does this indicate that AGP is running at 4x? I just want to ensure that 8x is, in fact, enabled. I can provide more info if necessary. Thanks.

Hi:
Usually, KT400 MOBOs set the AGP to 8x automatically when the card supports it.
To know if your card is running at 8x, view your card settings (or properties).
Hope that helps.
Edyros!

Need help setting AGP Speed

The motherboard is K8T Neo-FIS2R with the lastest Bios 1.1. I am running Win XP Service Pack 1. The video Card is Radeon 9800 XT with the lastest driver. In the Bios of the motherboard, the AGP Mode is Auto and it will not allow me to change that. Fast Write is Enabled.
My problem that I'm having is when I'm view the APG Speed in the Advanced setting for the Video Card, the Current AGP Speed is set to off and Fast Write is off. When I changed the setting to AGP Speed 8X and Fast Write Enabled, I have to reboot the system and after reboot, the seting went back to the original (AGP Speed is Off and Fast Write is Off).
Why is it doing this? During installation of Windows XP, it never ask for any driver except for the Serial ATA. Do I have to install some driver that came on the CD with the motherboard? I went to view the CD but the CD is bad, the CD drive would not read it but read other CDs just fine. I went to the MSI website and looked at drivers for this board and saw VIA Chipset 4 in 1 Driver. Do I need to install this? If so, will it override the Serial ATA driver that I have to install before installing Win XP?

If it scrolls that way, its NOT because you run AGPx4 and NOT because fastwrite is disabled. That is only a driver problem.
It's best to disable fastwrite anyway. Gives no extra peformance and makes the whole system a little more unstable.
There is also NO or very little (minimal) performance gain from AGP4 to AGP8.
Be sure to use the catalyst uninstaller from ati.com before installing the drivers again

Setting AGP 8X!

Ok,
Please read this bit dont give me the same old answer!
How can i set the AGP 8X from this certain motherboard:MSI MS-6712 1.0 and a Inno3D GeForce FX 5700.
I cant seem to shift it out of PCI mode.
I definatly know that my motherboard+card is AGP 8X compatible, but i found no way to set it.
I run Win XP Pro, 1004mb ddr ram and 120 (111)gb hard drive, any more info needed, feel free.
Ok,
Thanks in advance,
Rob

I am sorry for being demanding, i didnt realise.
Here is the link where i bought my mainboard from:http://www.savastore.com/include2/info7.asp?catalog%5Fname=Savastore&product%5Fid=10268629&pid=40
I am using a different sound card but thats about it.
Where can i download the drivers from?
Sorry again,
Merther

Can't set AGP speed

Hello,
I have the A64 3200+ and the MSI K8T NEO Fis2r... with a Radeon 9800 XT.
I cant set a AGP speed for the 9800xt, in the bios its auto, and I cant change that. In the smartgart in advanced display options for the vid card, I can set the speed, but it always goes back again to 'off'..
can anyone help me? I have all the newest drivers and bios!

Try a fresh install installing the OS, updates, via drivers, then vid drivers. Or try running the AGP at 4x. It resets back to off when it fails the setup test.

Bios Request to set AGP 4x on KT400's

I own some MSI KT4VL (rev 1.0 w/ latest bios) and some Radeon 9700 Pro - Eventhough it is running fairly decent, I do experience lock-ups and this is annoying...I've posted the details in the Radeon 9700 and KT4 thread here in this forum...
From what I've read from other users experiencing lock-ups issues with the 9700 Pro and KT400 motherboards, a lot of them were able to set AGP 4x (instead of AGP 8x) as a workaround and get the 9700 to run nicely - With the MSI KT4V, the AGP mode cannot be changed from AGP 8x - Would it be possible to make a request and get a biod which would allow AGP mode to be changed so that we (the consumers) could get on and try out this workaround (this would ease the pain)...Bas, Maesus, can you guys inquire and make such a request?
Much appreciated,

There are KT400 motherboards out there where you can set the APG speed mode other than 8x - The Asus a7v8x for instance...
Here is a thread here where 'RavenShield1' set the AGP speed to 4x as a workaround to fix the lock-ups...I will add more examples and just wanted to point you to this one in the meantime...
The bios for the KT400 MSI mobo's according to the manual is supposed to let you set the AGP mode but whatever GPU I run, I got no way to change it...

Stable Gf4 Ti4800 se became unstable on new motherboard

My Gf4 Ti4800 se ran perfectly on my QDI kt333a motherboard, but now that I've upgraded to an asus a7n8x-8 motherboard it has colour corruption even in the bios. Letters are still present, but large blocks of text will have their colours incorrect etc. In Windows the corruption is much smaller, but still present. It is instead the size of a few pixels here and there. The colours can be corrected by highlighting the text, image, etc with the mouse then removing the highlight.
This is with the newest drivers and motherboard bios. The new motherboard works perfectly with a Radeon 9800. The old motherboard only ran the card at agp4x, where as the new one had 8x capability...as the card advertised it was capable of.
I have a Barton 2500+, not oc'd, and 1gb of ddr333 ram. Windows XP sp1. all newest drivers/bios, & fresh install.

Piezo,
The card should run at 8x, but for testing purposes lets try:
First uninstall the Video Drivers and the Mobo Drivers, then install just the nVidia 3.13 Drivers. They already have the ForceWare Drivers in then for the GeForce4 Ti card.
If that does not work, set the AGP to 4x and disable sidebanding in the BIOS.
Let us know what that does.
Take Care,
Richard

AGP 4x problem?

Just installed a GF4 Ti4200 128Mb card, and d/loaded the latest VGA drivers from MSI (but not BIOS update - if there is one!) I'm running Win98 SE on a PIII/866 with 256Mb. Seems to be working except I can't change the AGP setting in the 'MSI Information' dialogue box from its default(?) value of 1x. (My M/B BIOS is set to AGP 4x and my VGA setting is set to AGP). In fact, I can't change ANY of the settings on the 'MSI Information' dialogue box.
Running dxdiag.exe shows me that there is a problem when running the 'Test Direct3D' test using the hardware accelerated DirectX 8 interface - it gives the error message:-
'Direct3D test results: Failure at step 5 (GetDeviceCaps): HRESULT = 0x8876086a (3D not available)'.
Incidentally, the frame rates in MS Flight Sim 2002 aren't much higher than they were with my old ATI Rage Magnum 32Mb card.
Any ideas/thoughts on this? I'd be very grateful for some pointers. Thanks.
Howard

I would recommend a total reinstall of the system. Having had another videocard previously installed tends to mess up pretty much that is connected to videodrivers and 3d (direct x).
Even if you have run with a videocard in the same familily of cards (such as going from a GF2 to a GF3) you will most often benefit from a total reinstall and gain 3d performance.

875p, I CANT LOCK my PCI / AGP Frequency using FAST,TURBO, or ULTRA

i have an 875p neo. i am one setting away from loving this mainboard(finally). i have a 2.8ghz running at 3.0 (with a 1:1 FSB/RAM). i can run stable in TURBO MODE, with "timings by SPD". i am using 1.7 bios (1.8 gives me lower performance). i tried all the bios from 1.4 and up. my problem is I CANT LOCK MY AGP/PCI frequency. no matter what, it boots up in windows as 70/35, but only when using FAST,TURBO,or ULTRA PERFORMANCE MODE. my agp/pci frequency locks fine at 66/33(67/34) if i run in SLOW MODE, but any other performance mode setting overclocks the AGP PCI frequency to 70/35. this causes my ATI 9700np to freeze almost instantly while playing any game. luckily my ATI card has unlocked bios or the problem would be worst. i have been using CLOCKGEN to throw the settings back to 66/33 when windows loads, and i get no freezes. BUT I WANT A PERMANENT FIX MSI. not a CLOCKGEN patch. my question to you all out there:
IS THERE A particular BIOS THAT I CAN USE THAT will LOCK THE PCI/AGP FReQUENCY while using FAST,TURBO, and ULTRA PERFORMANCE MODES? or another way to lock the setting in the bios?any suggestions? thanks
EDIT 2:
i just remembered, i forgot to tell you all. my agp/pci lock works fine if i run my ram in 333mhz mode. i have 400mhz ram. i was a running 1:1 ratio. agp/pci doesnt lock only if i use "auto" or "400mhz" settings. it run fine when i have my ram set to run at 333mhz. are you runnig at 400mhz or 333mhz? if 333mhz i can see why i left you guys confused...sorry.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!MY FIX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WELL I GUESS WE HAVE TO USE THE GHETTO FIX FOR NOW:
(i am assumming this is an ATI CARD only PROBLEM)
download clockgen and install it. check your AGP/PCI frequency. if it reads 70/35 then you have a problem, which will cause your ATI card to freeze up during a period of use.
unlock your cards bios(if it's not already unlocked). this will allow room for the 70/35 AGP/PCI frequency overclock. get info from rage3d.com forum on how to unlock your ATI card.
make your clockgen settings startup when windows boot, @***ghz, 66/33 agp/pci(read the clockgen instructions on how to run clockgen on boot)
download radclocker and install it.
set the AGP core/mem clock speeds to what you desire. then bump down the core TWO NOTCHES, then the memory down TWO NOTCHES then click "use current" bios button. 70/35 boot overclock pushes your ATI core/memory up two notches, so by setting radclocker 2 notches , radclocker takes the 70/35overclock two nothes lower. you have your desired speed. then clockgen throws your agp/pci frequency back to 66/33....which makes everything work right. it all boots in the right order for me.
explaination:
when windows starts it boots your agp/pci frequency@ 70/35. you need to be at 66/33 AGP/pci frequency for your ati card to run correct and not lock up after intense gameplay. radclocker underclock your card.clockgen puts your agp/pci to 66/33 AGP/PCI frequency.

AGP aperature size in BIOS

In the BIOS there is an AGP aperatire size setting and I was wondering what this setting should be set to. There are options for 64mb, 128mb, and 256 mb. I have a PNY GeForce FX 5600 256MBS DDR Ram. And does this setting even affect performance?

This BIOS feature allows you to select the size of the AGP aperture. The aperture is a portion of the PCI memory address range that is to be dedicated for use as AGP memory address space. Host cycles that hit the aperture range are forwarded to the AGP bus without need for translation. The aperture size also determines the maximum amount of system RAM that can be allocated to the AGP graphics card for texture storage.
The AGP aperture size should be calculated using this formula : maximum usable AGP memory size x 2 plus 12MB. The actual usable AGP memory space is less than half the AGP aperture size set in the BIOS. This is because the AGP controller needs a write combined memory area equal in size to the actual AGP memory area (uncached) plus an additional 12MB for virtual addressing. Therefore, it isn't simply a matter of determining how much AGP memory space you need. You also need to calculate the final aperture size by doubling the amount of AGP memory space desired and adding 12MB to the total.
Note that the AGP aperture is merely address space, not physical memory in use. The physical memory is allocated and released as needed only when Direct3D makes a "create non-local surface" call. Windows 95 (with VGARTD.VXD) and later versions of Microsoft Windows use a waterfall method of memory allocation. Surfaces are first created in the graphics card's local memory. When that memory is full, surface creation spills over into AGP memory and then system memory. So, memory usage is automatically optimized for each application. AGP and system memory are not used unless absolutely necessary.
It is quite common to hear many people recommending that the AGP aperture size should be exactly half the amount of system RAM. However, this is wrong for the same reason why swapfile size shouldn't always be 1/4 of system RAM. Like the swapfile, the requirement for AGP memory space shrinks as the graphics card's local memory increases in size. This is because the graphics card will have more local memory to dedicate to texture storage. This reduces the need for AGP memory. So, if you upgrade to a graphics card with more memory, you shouldn't be "deceived" into thinking that it will therefore require even more AGP memory! On the contrary, a smaller AGP memory space will be required.
If your graphics card has very little graphics memory (4MB - 16MB), you may need to create a large AGP aperture, up to half the size of the system RAM. The graphics card's local memory and the AGP aperture size combined should be roughly around 64MB. For cards with more local memory, you needn't create quite so big an aperture. Note that the size of the aperture does not correspond to performance so increasing it to gargantuan proportions will not improve performance.
Still, it is recommended that you keep the AGP aperture around 64MB to 128MB in size. Now, why is such a large aperture size recommended despite the fact that most graphics cards now come with large amounts of local memory? Shouldn't we just set it to the absolute minimum to save system RAM?
Well, in the first place, many graphics cards require an AGP aperture of at least 16MB in size to work properly. This is probably because the virtual addressing space is already 12MB in size! In addition, many software have AGP aperture size requirements that are mostly unspecified. Some games actually use so much textures that a large AGP aperture is needed even with graphics cards with large memory buffers.
And if you remember the formula above, the AGP aperture must be more than twice the size of the desired AGP memory space. So, if you want 15MB of AGP memory for texture storage purposes, then the AGP aperture has to be at least 42MB in size. Therefore, it makes sense to set a large AGP aperture size in order to cater for all eventualities.
Please note that reducing the AGP aperture size won't save you any RAM. Again, what setting the AGP aperture size does is limit the amount of system memory the AGP bus can appropriate when it needs to. It is not used unless absolutely necessary. So, setting a 64MB AGP aperture doesn't mean that 64MB of your system memory will be appropriated. It will only limit the maximum amount of system memory that can be used by the AGP bus to 64MB (with a usable AGP memory space of only 26MB).
Now, while increasing the AGP aperture size beyond 128MB won't take up system RAM, it would still be best to keep the aperture size in the 64MB-128MB range so that the GART (Graphics Address Relocation Table) won't become too big. As the amount of local memory on graphics cards increases and texture compression becomes commonplace, there's less of a need for the AGP aperture size to grow beyond 64MB. Therefore, it is recommended that you set the AGP Aperture Size to 64MB or at most, 128MB

Anyone else have an AGP card that\'s seen as PCI in device manag

Does anyone else have an AGP card that's seen as PCI in device manager > display adapters > general > location PCI bus 1,device 0, function 0
I'm running Win2k and that's what mine says
I have my video set to agp in bios :(

I think that is correct, even though it sounds strange (sometimes USB is seen as COM3). But if you are not sure about the status of the AGP, use a program like WCPUID . Sometimes, under Win98 the AGP is not enabled unless you install first the drivers for the motherboard.
