G400 only AGP 4x compatible but can not run at AGP 4X speed!!!

Marmita: what exactly was that run-on? It seemed like it was informative, but shrouded in a mystery of nonpunctuation.

LrngToFly: Er, Intel is going to release the chipset then. That has no bearing on reality, or when production motherboards will be on the market. If you think you'll be able to get a Camino motherboard next Monday, you're wacky.

Giant Intel is continuing to have problems with the introduction of a somewhat mundane product that enables the main processor work with the rest of the computer.

Next Monday, Intel will debut its 820 chipset, but the advanced set of ancillary processors has been resisted by PC manufacturers. The 820 utilizes a new memory technology called Rambus, but PC makers so far prefer the established standard, synchronous dynamic random access memory (SDRAM), which is cheaper.

Analysts say that the 820 is facing limited demand, and at least one asserts that Intel has reduced its production plans.

My g*d, LrngToFly, at least keep up with the news! or head over to the shallow end and impress the toddlers...!

Geez.

Forget 4x and forget Camino. Intel is going to piss off alot of people when they release Carmel right after Camino with an AGP2 slot.

I am using VIA Apollo 694 ChipSet Mobo(like i820 support AGP 4X mode transfer) for the testing. The AGP slot AGP Universal Slot. It support 1x, 2x and 4x mode.

I have test other display cards :

1. Diamond Viper V770 : 4X mode support 1X, 2X transfer mode support, running at 2X mode

2. Creative Lab TNT2 Value : 4X mode support 1X, 2X transfer mode support, runing at 2X mode

3. Elsa ErazerIII TNT2 : 4X mode support 1X, 2X, 4X transfer mode suport, running at 4X mode

4. Diamond Stealth III(S3 S4pro) : 4X mode support 1X, 2X, 4X transfer mode support, running at 4X mode

5. 3DLabs Permedia 3 : 4Xmode support, support 1X, 2X transfer mode, running at 1X mode

6. Matrox G400Max(my card) : 4X mode support 1X, 2X transfer mode, running at 1X mode


The meaning of support 4X mode is : Can boot up windows9X and pass 3DMark testing when enable 4X mode support enable at BIOS.

The conclusion is :
TNT2 support 4X mode , only run at 2X transfer mode

TNT2 Ultra support 4X mode , can run at 4X transfer mode

Savage 4 Pro support 4X mode, can run at 4X transfer mode

Premedia 3 support 4X mode, only run at 1X transfer mode

G400 support 4X mode, support 2X mode transfer 2X mode, but my card only run at 1X transfer mode if forced to 2X will crush up. But I like to use G400

Hmmm Will Matrox enabled the 4X transfer mode and fiex my 1X transfer mode at next BIOS Update ?

Is that all of you can run your Max at 2x transfer mode without out problem ?

G400 Max 2X no problems (pcilist says 2X and tops out at 2X)

TNT2 Ultra 2X (pcilist says 2X and tops out at 4X)

Of cource no 4X mobo/chipset to test with here

So I guess Max can only run at 2X but will fit in 4X mobo, and TNT2 Ultra can run at 4X but won't fit in 4X mobo. Can't win for loosing.

PurpleHaze: What I ment is that the faster the agp goes it's less important how much memory u have on the graphic chip... the smartest way to go is to have one memory storage that any part in the computer can use...
lets look at the future for a moment:
Lets say you have a x8 agp with 512mb ram and 512mb memory on the 3D card.. so you have 1Gig of memory to use when you are running lets say Quake5... thats very good, but the problem is that the 512mb that you have on the graphic card are dedicated to it only.. no other part of ur computer can use it and I think it's quite a waste. a better solution is 1Gig of ram that the card can access at x8 AGP speed and a little amount of memory as a "Texture cache" that will be places on the card itself. The same thing goes for sound cards but the amount of memory needed for it are much smaller... In the long run AGP (or alike architectures) is the way to go and splitting the memory between the computer cards is a big waste, we are paying good money this memory.

Marmita only one part of the pc can use that memory at a time. If two parts want to access it at the same time, one will have to wait. The result is a much slower pc.
