Anybody know what card I can use for this motherboard? It is an Asus P4S8X with a Sis648 chipset.The manual says the AGP slot will support any AGP 8X/4X/2x 1.5V cards.
The Radeon X850pro uses 12v direct from the power supply.Can this be put in the slot?—or should I just go for a less powerful card.
My current card is a GeForce4 Ti4200(now deep-fried).

Any of todays agp 4x or 8x cards will be ok.
The fact that the X850pro uses 12v direct from the power supply is nothing to worry about.

The 1.5V refers to the voltage of the AGP slot as apposed to the voltage required to power the card. As the previous reply mentions all modern AGP cards work with 1.5 volt AGP slots. As the X850pro requires a direct input from the power supply you should make sure this is powerful enough, a 400watt PSU should be enough but the more the better.
Enjoy your new card!

The only 3.
0V AGP cards are the very (very!) old ones. There is no x850 with a 3.0 volt interface in existence.

Thanks for the info!! My power supply is only 300w.The computer is 3 years old,so rather than get into a cascading pile of upgrades,I am looking for a more compatable card!

If you stick with the 300w PSU i would recommend getting a cheaper card. I’ve never used ATI cards so i’ll stick to what i know and suggest the nvidia geforce 6200 or 6600 (not GT!) as these will show a massive improvement over your Ti4200 (i used to have one) and should work fine with a 300w PSU. I suppose the radeon 9800 or x700 would be similar, but as i said i’m not as clued up on these!
Also if you could give more specs of your PC it would help, as there’s no point going for higher-end cards if your other components aren’t up to a similar standard.

Hi Cookiedude I think you sold me on a 6200.
The Asus N6200/TD128mb is going for $80 at Bestbyte.
The rest of the system is a P4 2.4cpu Western Digital 80g 7800rpm.Only 512 ram DDR333,but I am going to double that.

The 6200 should suit your system well. Its always good to have as much RAM as you can afford too, plus DDRs pretty cheap at the mo. So doubling that’s a good move.

Case closed—I bought and installed the 6200.
Now I have another problem!!
With the drivers from the disk installed,I could use the smart doctor over clocking utility.At that point I also had the Asus enhanced driver and the Nvidia driver.
Before I downloaded the new driver I went to the remove programs utility to blow away the old drivers. There were 2 programs,asus enhanced showing memory used,and Nvidia with no memory being used.Blew both away.downloaded and installed new driver.Tested it on Quake 4 demo-not too bad!!-Tryed to use the smart doctor to overclock—The Message:Asus enhanced display driver not installed!
AND-the asus support site is not available at this time-try again later!!
I searched both my mobo disk and agp disk for this driver with no luck-and I don’t want to re-install the card software again-Probably have to update and go in circles again!!

have u installed the latest nvidia drivers from their website.
Also if u want to OC ur card then ive always found CoolBits to work well, its nvidia’s own OCing facility and is usually inherent on all nvidia cards it just needs activating. do a search for coolbits in google n it’ll bring up all the info you need.
As for the ASUS drivers i would suggest renistalling software for your card from scratch then, rather than deleting any of the drivers, update using the latest nvidia drivers.
Personally i prefer not to overclock my graphics card as some recent games refuse to run properly with overclocked hardware, such as Doom 3.

Man ,you are a wealth of info—I was considering that option.
The nice feature with the Smart Doctor is that it gives you a display with sliders so you can bump up the core and memory speed a bit at a time.

CoolBits works the same way, slider for memory and a slider for core. You tend to get seperate settings for 2D and 3D so if you only want OCing while running games you only adjust the 3D settings.

I have found that my machine is compatible with only AGP 4x,1.
5v cards
So, please tell me the best available AGP 4x,1.5v graphics card, my mother board specification is in the below link..
*www.mercury-pc.com/product-spec.php?productid=90
Other system spec:
CPU: Pentium 1.4 Ghz
RAM: 640 MB
please mention the hardware changes i need to do like… power supply,etc.. but i am not planning to change the motherboard, because my plan is to just add a graphics card, and any other minor changes and use it for gaming…
Please dont ask me to buy a better pc, i just dont want to waste this pc, any card and any game with any graphics level possible will do for me, i dont bother if cant even play the latest games with lowest graphics setting also..
Please just mention the best Graphics card for this config…
Thanks

Forget gaming in this one.
However you can try to get a 7600gs or 7300gt. But you dont even hav a 8x agp slot

I think its better to upgrade to a current generation Core2 or Phenom architecture CPU rather than wasting money on this system. If you buy a GPU to play good games, you need to shell out a lot of money, and when you upgrade, all will be useless later. So either upgrade now or sit with the rig in its current state.

Accepting that you won’t or can’t shell out for a new system now, a GF6600GT will do quite nicely.
A 7600GT will be even better, but an AGP version is probably quite difficult to get, and it will be bottle-necked by your CPU.
It won’t make much of a difference that your gfx slot is 4x and the card is 8x. I suggest that you hunt for a used 6600GT for around 2k.

Thanks for the replies..
I have access to more powerful system. but i am just trying to use this system also.. The system is not too slow and it plays CS 1.6, Quake III, etc i am just trying to make it better instead of keeping it idle i can use it to play some good games not latest ones.
I think I have found the GeForce 7800 GS & GeForce 7600 GT(also said by few here) (see attachment) in the nvidia website.. what u guys think about these cards and which will be compatible, and how to find whether it is 1.5v? I couldnt find a very detailed specification page…
and which one is best ?

7600GT,7800 are good cards. it will run all latest games. but don’t know how it will perform on yr system.u need good procesor & ram also.
so don’t waste yr money on it.
Try nvidia6200 or ati x series.it will not run latest games,but u can play good title like nfsu2,mw,carbon,fear,hl2,hl2-epi1,1,tombraider legend & anniversary,etc.
second option is go to local assemble pc shop,if they exchange parts or not. if yes then upgrade ur ram,processor,mobo.

I think you can try to see if you can get a *REASONABLE* deal with this Rig of yours. If its pretty enough a deal, then go and either get a VIA+Sempron headless system for use as a downloadbox, or keep the money and smile.

Do you mean that «nvidia6200» is the best in the GeForce 6 series? or how would you measure my system and tell that the 7600GT,7800 GS couldnt be compatible, just curious?
Thanks for the Replies…
Any ideas?

6200 is bad card now. but it is good for u if u want to keep this system.
7600,7800 need 8x agp slot i think. don’t know about 4x.
what about yr power supply??? normal i think.u need good psu for that.
afterall it’s yr choice.

No. Except for some onboard (IGP) versions, a 6200 is the lowest in the GF6 series. A 6600GT is twice as fast. Comparing the universal popularity of gaming cards in their own time, the 6600GT was probably the most popular one ever. And a 7600GT is roughly 50% faster than a 6600GT.

Again.
. Hello all..
I went to my city’s all big vendors and found that most of them only had GeForce FX 5500 and one vendor had GeForce LE 6200 XFX, the vendors agreed to my request that I will just take my system to them and they will fix the card and if it works then only i will buy.. and they said that there is no demand for AGP cards nowadays(may be much less in my city), so they are not having more AGP cards stock, also they wont be able to order a higher model for me, as they wont be able to return it, if it is not supported by my config..
So what you guys think and shall i buy 6200 ?
Thanks
Any suggestions???

Accelerated Graphics Port (AGP)
- Details
- Parent category: Motherboards
- Category: Local buses
To improve video and graphics performance, Intel developed a new bus in the mid-1990s called the Accelerated Graphics Port (AGP).
This bus is similar to PCI, but contains a number of additions and extensions. And physically, and electrically, and logically, it does not depend on PCI. For example, the AGP connector is similar to the PCI connector, but has pins for additional signals and a different pinout. Unlike PCI, which is a true multi-socket bus, AGP is a high-performance connection designed specifically for a video adapter, and only one AGP slot is allowed per video adapter in a system. The AGP 1.0 specification was first released by Intel on July 1996 years old This specification used a clock frequency of 66 MHz and a 1x or 2x mode with a voltage level of 3.3 V. AGP 2.0 was released in May 1998; it added 4x mode and lowered the operating voltage to 1.5 V.
The latest version of the AGP specification was version 3.0 — for the AGP 8x bus. It defines a data transfer rate of 2133 MB / s, which is exactly twice as much as that of AGP 4x. The AGP 8x specification was first publicly announced in November 2000.
Support for AGP 8x is currently implemented in most motherboards from major manufacturers. Despite twice the bandwidth compared to AGP 4x, the practical differences between 4x and 8x compatible devices are minimal. At the same time, many chipsets that support 3D graphics have upgraded the frequency of graphics cores and memory, as well as the architecture of the graphics subsystem, so that they can better support a faster interface. nine0011
Most newer AGP video adapters support the AGP 4x or 8x specifications, both of which require 1.5 V. Many older AGP 2x motherboards only support 3.3 V. Installing a 1.5 V video adapter The 3.3V slot can cause physical damage to both the adapter and the motherboard itself. To avoid such situations, special connectors are provided in the AGP specification. As a rule, adapters and slots have connectors that allow you to install cards with a voltage of 1.5 and 3.3 V in slots with a voltage of 1.5 and 3.3 V, respectively. However, there are universal slots that allow you to install video adapters with different voltage levels.
The location of connectors for AGP adapters and the types of motherboard slots depend on one or another AGP standard (see the figure below). nine0011
As you can see from the figure, AGP 4x and 8x (1.5 V) video adapters can only be installed in 1.5 V AGP slots or in universal 3.3/1.5 V slots. Design of slots and connectors adapter does not allow you to install a 1.5V adapter in a 3.3V slot. So don’t worry if your new AGP video adapter won’t fit in your old motherboard slot, as it will only benefit both the adapter and the board itself. . In this case, you need to replace the video adapter or purchase a motherboard with an AGP 4x/8x slot that supports 1.5 V.
Attention!
Some AGP 4x compatible mainboards can only use 1.5 V AGP 4x boards. Therefore, before purchasing an AGP board, make sure it is compatible with your existing mainboard. In addition, some AGP 4x-compatible slots use a board locking mechanism (Fig. 4.79). Older AGP 1x/2x connectors have a pronounced divider that is not present in the newer AGP 4x connector.
AGP 8x cards can also be inserted into the AGP 4x slot. nine0027
The new AGP Pro 1.0 specification was introduced in August 1998; in April 1999 it was revised in the new edition of AGP Pro 1.1a. It defines a rather long connector with additional pins on each end to supply power to AGP boards that consume more than 25W (maximum power is 110W). AGP Pro boards can be used in high quality graphics workstations. AGP Pro connectors are backwards compatible, i.e. standard AGP boards can be connected to them. Since the AGP Pro connector is longer than the AGP 1x/2x, there is a possibility that the AGP 1x/2x card will be installed incorrectly, which may damage it. To avoid this, the AGP Pro extension, located at the back of the connector, is sometimes covered with a special cover. This cover must be removed before installing the AGP Pro board. nine0011
AGP 1x/2x, AGP 4x and AGP Pro standard connectors shown.
The AGP bus is a fast connection that operates at a base frequency of 66 MHz (more precisely, 66.
66 MHz), which is twice that of PCI. In the basic AGP mode, called 1x, a single transmission is performed every cycle. Because the AGP bus is 32 bits (4 bytes) wide, at 66M cycles per second, it can transfer data at approximately 266MB/s. The original AGP specification also defined a 2x mode, in which two transfers are made in each cycle, which corresponds to a speed of 533 MB/s. Currently, almost all modern motherboards support this mode. The AGP 2.0 specification supports a 4-time data transfer mode (i.e., transmission occurs four times during one cycle). At the same time, the throughput reaches 1066 MB / s. Most modern AGP boards support at least the 4x standard. In table. Figure 4.77 shows clock rates and data rates for various AGP modes. Most of the new AGP video adapters conform to the 4x standard, while the latest models from NVIDIA and ATI support the AGP 8x standard. nine0011
Because the AGP bus is independent of PCI, using an AGP video adapter can free up the PCI bus for traditional I/O functions such as IDE/ATA, SCSI and USB controllers, sound cards, etc.
In addition to improving performance video adapter, AGP allows you to get quick access directly to the system RAM. This allows the AGP video adapter to use RAM, which reduces the need for video memory. However, some models of AGP video adapters have recently begun to be equipped with a sufficiently large amount of high-speed memory (up to 256 MB). The use of native memory is extremely important when running demanding applications, such as modern 3D games. Modern AGP video adapters are capable of not only running games, but also playing full-fledged dynamic video on a PC. nine0011
AGP 8x bus (2133 MB/s) is 16 times faster than 33 MHz 32-bit PCI bus (133 MB/s) but twice as slow as PCI Express x16 bus (4000 MB/s). Beginning in mid-2004, motherboard manufacturers targeting the high-performance Pentium 4 and Athlon 64 processor market began replacing AGP 8x connectors with PCI-Express 16x connectors. In 2006, most motherboards of all price categories were already equipped with PCI-Express 16x slots instead of AGP.
This trend definitely marks the end of the AGP era. nine0011
Note!
If you want to purchase a motherboard with a PCI Express x16 slot but don’t want to change the AGP video adapter, look for a motherboard model that has both AGP 8x and PCI Express x16 slots. Similar motherboards are available for both Pentium 4 and AMD Athlon 64 processors.- < back
