Just a simple question.....

[YeaYea&#33&#33&#33]

Hey guys what is the one problem you know I am gonna experience with this motherbaord? Im getting it up and going when my x1800xt gets in.

Thank you guys.

With your sig config, you may have some problems with the Plextor PX-716A.

In order to correct the corrupt recorded data issue you need to force the Plextor to UDMA2. Check this for explanations on how to do it.

Only problem i see is if you want Crossfire, as like me you have bought the wrong board, these boards are only for x800 series Crossfire, the proper Crossfire boards for the X1800 series are due around Febuary. :mad:

[bikspk]

I'm running that setup right now and it's working okay. Don't know about the "due in february - http://www.pcconnection.com/ProductDetail?...SourceID=k22350" but am interested that the ones that are available are 256MB rather than 512MB and don't know how that would affect performance.

 

1) Make sure you put the memory where it belongs.

2) Good power supply with right power connectors (check).

3) Reboot issue that will drive you nuts (power down - power up works). Think it is a bios issue

4) My 3700 overclocks well but the FSB/HTT won't go up far.

5) Cheap memory won't play well with this board (check).

6) Don't count on the on-board audio if you are going to use mic. This may be an issue with my board but there sure is a lot of discussion about the Karajan audio module relating to front mic connector, etc (check XFi).

7) Browse the forums and, if someone has a complaint, read through the whole thread to the resolution since some people either give up and live with the problem, give up and RMA the board, figure out on their own then not post their resolution, etc.

8) Have another computer up so you can get to these forums if you have a problem.

 

Good luck.

Yes it works but very poorly, new boards in Febuary are for the x1800 series as they have the new RD580 chipset, x1800 crossfire on those boards runs amazing, whoops SLi, where as on these boards that are designed for the x8 series, it hardly beats 2x GT's, 5fps faster if that infact, these boards should have been out about 9 months ago, thats why they are designed for the x8 series. :mad:

 

Still its only a mobo ive gota bin.

[BSteng]

so for those of us wishing to use our x1800 series cards in crossfire mode, we would need a new mobo?

[Daedalus]

If you don't want a new mobo no, as they do work on these boards, but as said they work atrociously as these were designed for the x8 series, as i said these boards are over 9 months late, ive just been reading some more reviews, and they are getting absolutely hammered by the 256mb GTX's in SLi, in most tests by over a whopping 40fps!!!!, but on the new chipset they wallop the GTX's.

 

here is one review, just look at how they get slaughtered by over a whopping 40fps once you crank the res up to 16x12 and above, these boards must be absolutely crippling the x1800's if on the new boards tables are turned and SLi is walloped.

 

Its a pity thay aint got the GT's in SLi on there to, as even they beat the XT's on this piece of carp, Nvidia must be wetting theirselves with laughter.

 

If you want to go Crossfire with an x1800 on this piece of ****, then by all means go ahead as it does work, but absolutely atrocious so be warned.

[Daedalus]

Heres the board we should get in this review, doesn't use the crappy RS450 ?Southbridge, it uses the ULI M1 575, which fully supports SATA2, no USB2 speed issues etc..., this is how x1800's should perform.

Heres what we get here on our pieces of crap, big difference you see, its the same all over in reviews, even whooped by the GT's.

 

If you want x1800 Crossfire, then like me you got the wrong board. :mad:

[YeaYea&#33&#33&#33]

Well thank you very much guys. I was wondering where my thread went and the fella from Portugual has been helpful as all of you have been. I am planning on upgrading to the RD580 in Feb as thats been the plan. I just want to get this PC going already, I really wish ATI released the mastercard for the x1800xt already.

[Daedalus]

Mastercards are on their way, probably arriving next week, go for the Asus board with the ULI M1 575 Southbridge if your going Crossfire with the x1800, as you can see from the results above, it does very well against SLi, where as on boards like this pile with this ****** Southbridge it gets whooped, even by the GT's, its the same across the board, any board using this crap gets whooped, the ones using the ULI M1 575 don't, Anandtech reviewed using the same Asus board as Guru, and the results are about the same, equal or better than the GTX's, and in some cases out performing the 512mb GTX SLi, but when you read reviews of Crossfire used on these SR450 Southbridges, they get well whooped, even by the GT's.

 

Don't make the mistake i made, get a better board, fair enough your getting the new boards in Feb, i may be to, but i still would'nt pair 2x1800's on this rubbish, its abysmal, and not worth it, just get the Asus board, besides DFi have another board coming now with the ULI M1 575 Southbridge i guess as that will perform much better than these.

 

Im actually considering binning this now, and just getting the Asus judging by the performance of it, i would'nt need to jump straight onto the new chipset boards in Feb.

Although I agree with you in the fact that the RDX200 misses the SATA II and the USB 2.0 performance, I disagree that the Asus A8R-MVP is better than the RDX200. I own a computer store, and I have already tested one Asus A8R-MVP, because I just like to test the hardware by myself. Well, I must say I am VERY disappointed with this Asus motherboard. Max Vcore is 1.50v with Overvolt enabled, Vcore is very unstable, does not like some TCCD memories (Gskill PC4400FC errors at default speed 200Mhz). Max HTT is 325, with active cooling on the ATI chipset and doesn't have chipset voltage control. RDX200 gives you 2.0v VCore (not that I need more than 1.85v) and 360/370 Mhz HTT.

I don't believe this Asus will solve all the problems that the RDX200 has. It is a fact that this Asus will solve the lack of SATA II and the USB2.0 performance is a little better than the RDX200.

To me, the RDX200 is still the best overclocker board with ATI chipset. The Asus A8R is a fine board, that just hasn't what it takes to be an overclocker's choice.

In the end, you get what you pay for. And if you really like to OC, than you will be disappointed with the Asus A8R. Save your money and spend it with a new board that has the new ATI Chipset.

 

For X1800 crossfire setup, I think we should wait for the next ATI chipset.

BTW, I saw something stating that RDX200 has passed ATI Crossfire certification with some new revision of the motherboard. If this is true, then we should expect better performance in X1800 Crossfire with the new revision of the RDX200.

 

Edit: Don´t blame the southbridge for poor Crossfire performance. Crossfire is controlled by the northbridge (the ATI chipset) in both boards. The issue with the RDX200 seems to be the electronic switch that controls the dual/single PCI-Express card operation. In the Asus this is controlled with a switch key that is inserted/removed from the upper PCI-Ex slot.
