After the damn Internet Problem i got it running, the newest ATI driver don't work, i get funny pics ... So i installed an older driver, activated Crossfire but aquamark 3 crashed all the time. And some mins ago i got the error RAM full ... can't start anything.

I'll NEVER build my own PC again ... They cheched for the parts to run together but nothing seems to work, i think the RAM error occures as soon as i activate Crossfire :(

But i can feell the power my pc :D the first 3 minutes of Aquamark 3 (Before buescreen) are running twice as fast(i think thats a hint that's something wrong) as my friends PC but with FPS of 190, he got 60 xD

Hope i will get crossfire working ... Damn drivers.

yea checkign the ram one stick at a time is good. Double check the mobo setup guide too make sure your using the default Dual Channel setup as well. Usually its 0+2 and then 1+3 for the ram banks. But maybe 1+3 need to be used before 0+2 you get the idea.

You can mixed one stick of your and one stick of buddies as well.. but your ram will downclock to the bus speed of the friends memory or vice versa.

you can also try Dr.Watson (built into windows) to help analyze when something crashes.

I have reports of and friends had it happen as well, where certain parts dont like each other.. not hardware wise driver wise.

For instance I think the Rapter HD and some ATI or PSU things are not as friendly for some ppl. If possilible use one of your other HDs as a boot drive and load windows there. and see if same errors occur, via either one mem stick or both and same with video cards.

As DeepOne was sayign about the MB allocations for RAM.
Basically opn my system i have a 4gb max on mobo. 1gb x 4 slots. if I try to use 4 gb. It will only show and use 3-3.5 in windows. This is due to the fact taht the 32bit memory allocations in winxp and the mobo. If it is server 2k3 32bit should be an allocation problem or on a 645bit version of windows. The system bios uses a chunk of the RAM to store system information which becomes unseen/un sualbe by windows 32bit non server.

I am slowly getting up to speed on DDR2. This may not be the same problem as with DDR. However Why would you go witH CL 5 RAM? I i have CL 2. Genereally the lower the timings the better.

Abotu defect RAm.. Well from what I have been told by stores and suppliers is that OCZ though really good RAM alos has teh highest returns. But I do not know how many of them are from overclockers. Because of that I went with Corsair.



What version of DX are you using? I th nk HoMM 5 should ask you to insatll DX9.0c make sure that is up-to-date.

And before i end this long post...

Make sure you do have the most Rescent Bios Version for motherbaord, DX, chipset drivers, if its a Raid board and you have sometjhing plugged into one of the controllers.. even though your no using raid make sure its disabled or at least (if avbailable) turned to an appropriate setting like SATA2 or SATA or siomething.




oh and with the 1900 Xfire and the 1900XT the xt will just prefrom as best as the Xfire edition card so the compatiblity is not really the issue. What Catylyst versions have youtried. You may need to have a Xfire driver edition installed first im not sure. but you should take a look in the advanced display protperties settings tab to see if there are any fine tunning or enalbing or disabling options when to do with Xfire.
