AGP and PCI-e on one motherboard?

Hi,

Firstly let me explain im not a noob to the computer scene i just ended up being given a lot of hardware that was left over from other pc's. About 3 months ago, i realised i had had a pretty crappy rig, so i got a GPU, a Radeon X1600 (AGP). It works great and i can run HL:2 and Fear on full graphics.

So now i want to upgrade my cpu and my motherboard (which is a crappy old asus K8N). To be able to get the latest CPU's I need to upgrade to one with socket 939 (i think that is the latest AMD socket is it not??)

So now my problem is that I need a motherboard which supports AGP so my current card works, *also* supports PCI-e so in the future i can get PCI-e cards and also is new enough so I get a good cpu.

Is this even possible? If it is can i please have a recommendation on which CPU/Mobo pair to buy and how much it would cost me.

Many thanks,
Fluffman

Slicesoul is right and wrong, yes that board will do AGP and PCI-E, but it is not the latest AMD socket, socket 939 is being phased out (by now they have stopped producing CPU's the only ones left are those in stock...). If you want the latest AMD socket you are looking at socket AM2, and for intel 775 is still current.

I've just checked... and there is no AM2 mobo with AGP and PCi-E from asrock, not usre about other manufacturers.

BUT... the 939 dual VSTA that soulslice mentioned will take AM2 with the addition of a daugther card (if you can find them, I imagine that they might be tough to find.), read the specs on asrock site, this will take the DDR2 that the AM2 needs.

There might be a better option which is the asrock 775dualVSTA which will allow you to use your DDR and your AGP with a Core 2 Duo CPU...

The only chipset that REALLY supports both is the M1695/M1567 combo from ULi, the reason it supports both is because it's actually made up of two northbridges (a PCI-E northbridge and an AGP northbridge/southbridge combo chip in the southbridge location). The chipset functions well, and the Asrock board the other guy recommended is the only board I know of to use it.

I spoke up because I'm sure you'll see a few recommendations for other products that simply aren't adequate. The Asrock Dual SATA2 is the ONLY product to do it "right", and lucky for you it IS socket 939.
October 28, 2006 2:19:50 PM

Okay so i see that a Asrock DUAL-VISTA is the only way of doin this and there are some on ebay.

So thanks for that guys. :) 

So this mobo is socket 775 can anybody recommend any good 775 processors for less then $300 ?

please do not buy on ebay.

either of the two lowest C2D's E6300 or E6400 would be good if you were to go with Intel. They are very fast and very cool, look up some of the reviews of Core 2 Duo for data behind this.

The 939 option is still valid, but you'll need that daughterboard to utilise AM2.

I'm running the 775 and its fine by me.

I'd argue that the upgrade path of the 939 dual means that you have to buy DDR2 and AM2 at the same time as AM2 will not work with the DDR2, but with the 775 you can run on either DDR or DDR2.

Therefore the upgrade path is better on the 775, but thats only if you are cost constrained, especially given DDR2 prices right now.

thanks for all the help guys,

You can't mix DDR and DDR2 on either Intel or AMDs.

If you opt for 939 your existing 184pin DDR will work just fine and you don't need to invest into 240pin DDR2.

Like Crashman said

The 939Dual is virtually the only board that implements AGP and PCI-E correctly on the same board. In other words you get a real full speed AGP 8X slot and a real full speed PCI-E X16 slot and you can use both at the same time in fact I used 2 VGAs in mine for a while.

I have 4 ASRock 939Dual-SATA2 boards I got from newegg and have used a few more to build servers for clients and they work fine it's a decent board for the money.

The AM2 daughtercard is only $30 USD or about 15 pounds.

It is my understanding the 775Dual implementation is inferior.

As far as ebay is concerned, I use it all the time but I rarely use it for mission critical parts on my primary machines (mobo, CPU, RAM, etc).

was partway through posting when that last reply came in... apologies for the duplicate info.

simultaneous use of DDR and DDR2 is not supported, and it is not a board for overclocking, 5% max, VS >40% for C2D generally. Note that the PCI-E slot is physically x16, but electrically only x4, this is within the PCI-E standard and should not pose a problem, my 7900GTO copes fine with it, and scores about 10,000 in 3dmark05, which seems to be what is expected.

Linux, are you saying that you could use Am2 and DDR with the add on board, I did not think that you could. The OP originaly asked the question if 939 was the lastest AMD socket, and was assuming it was, however obviously it is not.

Negative, I did not say you can use AM2 with DDR.

All K8 AMDs have an integrated memory controller so you must use what the IMC on the CPU supports.

184 pin DDR for 754/939/940 etc
240pin DDR2 for AM2 / Socket F etc

The AM2 daughtercard has 240pin DDR2 slots for use with AM2 CPUs.

You really don't want to run your AGP8x card on a PCI slot, which is what the VIA AGP/PCIe combos do. Not only is it slow, but most boards won't even work with a non AGP2x compatible card because PCI signals are 3.3V.

AGP 1.0 is 2x and 3.3v, AGP2.0 is 4x and 1.5v, AGP3.0 is 8x and 0.8V. All 8x cards are 4x compatible (0.8V/1.5V) but only around half of them are 3.3V compatible (8x/4x/2x).

3.3V compatible cards have the forward voltage key, 1.5V compatible cards have the rear voltage key, 8x/4x/2x and 4x/2x cards have both keys. But these crappy PCI to AGP implementations often use an AGP Universal Slot, so that cards that don't work will still fit.

Precisely!

The PCI-E slot in not a real X16 slot and the AGP slot runs over PCI causing the issues Crashman described above.

It is not a very good solution at all ( as in the 775Dual ).

The 939Dual offers real 100% native AGP 8x and PCI-E X16 slots.

The other issue is DDR tends to somewhat cripple the Intel CPUs while AMDs still perform very well with DDR.

If you wish to go the AM2 route you would need the 939Dual-SATA2 or VSTA board + the AM2 daughtercard + an AM2 CPU + DDR2


If you take the 939 route all you need is your existing 184pin DDR + the 939Dual-SATA2/VSTA + a 939 CPU

Nope, the riser card has DDR2 memory slots, and w/o the riser you use the built-in DDR. With DDR2 memory prices way up, why not get the 939 solution anyway? Currently, there is still little benifit to AM2 using DDR2 memory, the benchmarks have shown this time and time again...

...by the way, there are two ASROCK mobo's that use the ULi chipset: the one in my sig, and the 939-Dual-Vista version. Either one works fine. Hmmm--Linux_0 has already pointed this out. Well, we agree, so perhaps we might know what we're talking about (OH NO! I can't believe that I'm agreeing with a LINUX user!) :lol:  :lol:  :lol:

the anandtech reviews show minor performance loss with PC3200 vs PC2-6400 in real world not enough to go and buy more RAM unless you had to anyway.

I've got the 775Dual, and it worked find with AGP and PCI-E so far, and have not noticed any performance issues, however I do accept that I have a sample of 1, and little other than charts to compare against.

The bandwidth in the PCi-Ex4 is enough, it appears, to feed a 7900GTO adequately. As a stepping stone board to get me to PCI-E and DDR2 and SATA I think it is a perfectly reasonable solution that does not mean I have to spend everything at once.

On a different note, does mounting the CPU sideways on the AM2 board cause interference problems with the HSF? or airlfow problems in the case?
October 28, 2006 3:24:31 PM

You missed the point.

The bandwidth problems with the 775 socket board are not the big problems, running in PCI mode is one of the big ones, and as Crashman points out:

Fx-55's are going for $200 on newegg.
They are single core, and the e6300 is faster than them.
Also the e6300 puts you on the new technology road :)

I went for the 6400 + VSTA a few months back, it came to just under 200 with delivery.

Had no problems with it at all so far, cpu runs ~40c all the time.
My old athlon 2800 ran at ~60c.

It's great for multi-tasking, runs fast at stock.

You can only get the FSB to 300mhz but who cares, its a very cheap board, anyone that moans about that is mentally retarded. It saved me over 400quid in my upgrade price (when you consider 2gig ddr2, an expensive mobo to make it even worth spending all that money on ddr2, pci-e graphics)

If it dies in a years time i'll have had my money's worth.

Indeed Crashman, bourgeoisdude and I agree that the AGP slot is crippled and has compatibility issues on the 775Dual while the PCI-E slot is not quite as bad although only PCI-E X4.

The 939Dual does not have this issue.

Also I am not aware of any cooling or other issues with the daughter card if you opt for AM2, although bourgeoisdude and I agree that you are probably better off with socket 939 which would be the most logical / inexpensive solution.

So its only an issue of making sure you buy a card that can take the voltage from that socket, not too big an issue surely?

The problem for the OP remains however the AGP slot is actually a VIA XGP slot which has stability and compatibility problems.

Since the OP needs a working AGP slot this board is not a good choice.

Many reviewers reported serious problems with the fake AGP slot on this board.

So the problem is stability, and not the fact that the AGP slot is keyed badly as per crashmans post.

I want to say 'And..?' (but i'm not going to as it helps no-one) as that link doesn't really tally with DOA's yes they do claim poor AGP performance, but have heard other people complain about stability, however as a very budget board for a CPU that generally forces a premium onto boards it is worth considering that you get what you pay for, I'll pay for 90% of the performance at 30-40% of the price...

Shall we just say that we disagree on this one, and that there may be a perception of problems with this board, but perhaps no more than other boards, I've lost count of the number of articles I have read here regarding 'my P5B doesn't...' and yet people still push it as a solution.

I take it you rode the short bus to school. I remember a movie where a guy spent several hours explaining a simple problem to some special needs people...

OK, so let me explain this slowly, so you can understand:

1.) AGP 1.0, 2x transfers, 3.3V
2.) AGP 2.0, 4x transfers, 1.5V
3.) AGP 3.0, 8x transfers, 0.8V

All current AGP cards: 8x/4x compatible, 0.8V/1.5V
Few current AGP cards: 8x/4x/2x compatible, 0.8V/1.5V/3.3V

9700Pro: 8x/4x/2x (supports 3.3V signals in addition to 0.8V and 1.5V)
9600 Pro: 8x/4x (supports only 0.8V and 1.5V)
X800/X850 AGP: 8x/4x (supports only 0.8V and 1.5V)

GeForce FX series: 8x/4x/2x (supports 3.3V signals in addition to 0.8V and 1.5V)
GeForce 6/7 AGP series: 8x/4x (supports only 0.8V and 1.5V)

Now you see the problem. Most of the older cards work in these slots (even powerful ones like the 9700 Pro), Most of the newer cards won't (even the whimpy ones like the X1600 Pro AGP). 3.3V did not go away in the Diamond Viper days, for ATI it went away with the 9600 Pro, and for nVidia it went away when they dropped the native AGP interface (moving to on-card signal converters).

Look at the original post, the guy said he has an X1600 Pro AGP. I'm almost certain the RAILTO chip is NOT compatible with 3.3V signals, certainly his card isn't keyed for 3.3V. I've actually tested the 9600 Pro on a few non-native "agp" boards, they won't even POST.

1.) AGP 1.0, 2x transfers, 3.3V
2.) AGP 2.0, 4x transfers, 1.5V
3.) AGP 3.0, 8x transfers, 0.8V

All current AGP cards: 8x/4x compatible, 0.8V/1.5V
Few current AGP cards: 8x/4x/2x compatible, 0.8V/1.5V/3.3V

9700Pro: 8x/4x/2x (supports 3.3V signals in addition to 0.8V and 1.5V)
9600 Pro: 8x/4x (supports only 0.8V and 1.5V)
X800/X850 AGP: 8x/4x (supports only 0.8V and 1.5V)

GeForce FX series: 8x/4x/2x (supports 3.3V signals in addition to 0.8V and 1.5V)
GeForce 6/7 AGP series: 8x/4x (supports only 0.8V and 1.5V)

Now you see the problem. Most of the older cards work in these slots (even powerful ones like the 9700 Pro), Most of the newer cards won't (even the whimpy ones like the X1600 Pro AGP). 3.3V did not go away in the Diamond Viper days, for ATI it went away with the 9600 Pro, and for nVidia it went away when they dropped the native AGP interface (moving to on-card signal converters).

If you say that they will not work, why/how did my 6600GT work, or Nix's 6800.

I was willing to accept you saying that they would allow cards that should not work to be fitted and hence be damaged / cause damage. But to say that the provided slot will not allow x4/x8 cards to work is not supported by the evidence.

Perhaps nVidia's AGP to PCI-Express converter is 3.3V signal compatible (which makes it odd that they wouldn't put the 3.3V key notch on the card). I checked with ECS to find out why some card didn't work, and they confirmed it was a signal voltage issue.

As for not damaging cards, there's a protection circuit for that (at least on some boards).

well i had run the asrock 775dual-vsta with his x1600pro agp and was running fine for a month back then. the 3dmark benchmarks sometimes exceeded 8 point from the tomshardware vga chart compared to the x1600pro agp.

now, with the same motherboard, i'm using sapphire x1900xt pcie card and also running fine :) 

i guess the 4x pcie is not a limit when playing 1024x768 or 1280x1024 resolution.

just my two cents, though..

So you're saying this particular board isn't using 3.3V signals common to so many other non-native AGP slots? That's a possibility too, one that would be easy to cross-reference using compatibility list.

i don't know much about voltage setting on the agp. the manual says to plug only a 1.5v agp card or something like that, not quiet recall.

i maybe wrong, but as far as i know, i've tried several agp & pcie cards (his 9200se agp, geforce mmx-440 agp, his x1600pro agp, asus geforce 6600 pcie, & sapphire x1900xt pcie), they all ran good.

9200SE is 3.3V compliant (2x compatible) as is the MX440. When my 9600 series cards didn't work on some boards, the only options I had left were older GeForce cards
October 28, 2006 6:55:37 PM

oh i see. is the 2x compatible means the speed of the agp mode?

i recall this motherboard only supports for 4x and 8x agp mode. hehe :D

oh gawd, reminds me of a song by RATT...

It doesn't matter what they say is supposed to be compatible in theory, all that matters is what they've tested and found compatible in practice.

A slew of boards with non-native AGP slots are "requiring" 1.5v or 4x/8x cards, yet actually using 3.3V signals (which come from 2x comptibility).

Ok this is odd... ASRock has a PCI-E VGA compat list but I haven't found one for AGP yet...

http://www.asrock.com/support/VGA/show.asp?Model=775Dua...

And you have to have BIOS P 1.40 or higher to use Core2 CPUs

I don't know if they tweaked the VSTA version of the board as far as the AGP goes.

Here's the chipset page:

http://www.via.com.tw/en/products/chipsets/p4-series/pt...



Again the VIA AGP+PCI-E solution is known to have problems. Maybe they corrected some of them in the latest version of the board however I would strongly recommend 939Dual + 939 CPU + existing DDR as that would be the least expensive solution and is known to have stable AGP and PCI-E support.

oh okay then. didn't know it before. thanks for the info.. :)

You can't geek up on AGP architecture all you like but working cards in slots can't be argued with.

My 6600GT works in it, my mates 7900GTO worked in the PCI-E slot too.

Heres my setup.

E6400
6600 GT
1.5gig DDR
80gig IDE Maxtor
300gig SATA Maxtor

No problems at all with AGP.
No problems at all with SATA.

The bios myth...Yes you need the new bios, thats because this board existed before core2duo, but all the boards from scan are v1.60 at least, i say this because mine was v1.60, thus its fair to say that their current stock will be at least that.


EDIT: you may well be right on the older versions of the board. The current versions however....
