In my experiences most of agp4x/8x card worked well on PII/PIII motherboards with agp 2x, but slightly slower because of that (but still VERY usable). So i am 99% percent sure that MX 420 will work with agp 2x. If not, try to upgrade BIOS to the newest version. Hope this will help. -dmc
Yes, AGP is completely backwards compatible.
Yes, However it just won't work at full speed.
AnswerYes.Added:Sometimes! Not all AGP 1x or 2x video cards will have the same connection type as 4x or 8x cards, some older cards will not physically fit in the slot for modern motherboards.
Typicaly it is 8x but on older computers it can range from 4x, 2x, and 1x.
it wont work with out the right one
Research your card and the specs for the motherboard of having a AGP 8x 1.5V the answer is, Yes. It will work.
The dimension 4550 motherboard supports up to 4x AGP according to spec. However, you can use an 8x AGP card as the specification is backwards compatible. It won't take advantage of 8x throughput but it should work just fine emulating 4x.
No. There's a reason there's AGP and then there's PCI-E..
Maybe. It depends on the AGP connector type of the motherboard and vga card. The ECS P4VXASD2.v1 motherboard has - I think - an Universal AGP slot ( not Universal AGP 3.0 !!) which can set 3.3 V or 1.5 V signal line voltage. The question is : What AGP connector does a vga card have ? Because of we are speaking about an 8x AGP card now the card connector type can be :AGP3.0 (in this case it won't work)Universal 1.5V AGP3.0 (it will work)Universal AGP3.0 (it will work).So the answer is : Try to find the voltage requirement or AGP collector type of card what you will purchase.If you have already bought the card and there is no signal from AGP (for example the monitor is dark )you can do a proof. Do the followings:check the card in an another computer with 8x AGP motherbord AGP slotif the card works try to find his "AGP driving control" value (for example on the working computer:PowerStrip->Adapter information->Report . You can see this value in a list. )note the "AGP driving control" value (it is a hexa value between 00 - FF)start the computer with motherboard P4VXASD2.v1 and enter BIOS setupgo to "Advanced Chipset Features" and see value of "AGP Driving Control" (the default is Auto)set it to FX5700LE's value"Save & Exit" from the BIOS Setupinstall your FX5700LE in the P4VXASD2.v1 motherboardstart the computerIf the "no signal problem" persists your FX5700LE has an AGP3.0 collector type.It means your card can not work together with your P4VXASD2 mobo. ( In this case you should set back in the BIOS the original "AGP driving control" value. It can be your old AGP will have a "no signal" problem now. If it was use a PCI card to set BIOS-value back) I hope , I could help you.Hi! I was asking similar question to ECS Technical Support (question was about different model of GeForceFX - 5200) The answer was that this mobo supports only AGP 4X graphics card (AGP 2.0), and it's not guaranted to work well with AGP 8X (AGP 3.0) cards. "This model is support AGP2.0(4X, 2X, 1X), so can not support AGP3.0 VGA card(4X/8X)" In attachment I got this: Differences between: AGP 2.0 // AGP 3.0 Signaling: 1.5V Signaling // New 0.8V Signaling Protocol: AGP1.0 + Fast Writes // AGP2.0 + Some enhancements - some deletions Speeds: 4X, 2X, 1X // 8X, 4X Connector: 1.5V keyed, Universal // 1.5V keyed, UniversalHowever, refering to the first answer, my graphics card's manufacturer technical support informed me that its connector is 1.5V, so it should work. I'll try the given proof and update my answer.
Yes, at 4x speed.
No it cannot you will need to get a agp card or upgrade your motherbord.
It will work, if it is compatible with the signalling voltage on the motherboard (1.5v for AGP 1x, 2x and 4x), but it will only work at up to the 4x that your motherboard is capable of. You may need to change your BIOS settings for AGP= 4x to obtain maximum performance from your motherboard and graphics card. AGP 8x cards run at 0.8v but some may permit 1.5v 4x compatibility. Those folks experiencing problems with 8x cards in 4x slots might consider the possibility of power supply issues. It's not unusual to see newer cards requiring 300-350 watt power supplies with specific voltages requiring up to 18 amps. Many old Dells and others have only 250 watt supplies, and the new dual gizmo gazillion megahertz screamers take a lot more juice than the factory-supplied cards. Some 8x cards are designed to be able to clock down to 4x, some are not. Many times it will say whether or not this is possible right on the box. In all respects the motherboard or 8x card should not be damaged by attempting this, the worst that will happen is it wont work. == == == == == ==
