According to cpuz runs the 3 of them @ x8Quote:

Icebob CPU-Z is probably wrong. Unless Intel did a special deal for that MB.
I thought that the nf200 chip will take care of that. Here's a quote from the Guru3d review:Quote:

The black PCIe slot is a x4 slot by the way. Hard to see, but all the way to the left you can also see a x1 PCie slot. "
running crossfire on nf200 :up:Quote:

Hey guys.
I havent followed this thred and just want to know how high are you pushing the voltage on the core for the 5870 cards? Is 1.35 to high?
I used 1.4V on my previous 4890s 6 months without a problem.
If you watch the temps of the voltage regulators and keep them under 65~70șC
youŽll be fine! Im gona push mine to 1.4 and keep it 24/7 but i have it watercooled and sinks with fans on the Vregulators.:up:
Thanks for the heads up bro.
how do you guys install the overclocking software in Windows7 X64?
its always tells me "driver not signed". I Can't even run rivatuner or other monitoring software (easytune6 etc)
Here is what I tested quickly on Vantage, i think increasing the frequency gpu carefree at 1020/1050 .

Well the default is 1.16v for the RV870XT. The RV790 has a default of 1.316. And the RV790XT (1GHz) is running on 1.4375v.Quote:

But we will have to wait a while until we know it for sure.
Hi guys,
Can someone get me a bios unlocked XFX HD5870 ??
My video card is XFX and I would like to use an bios XFX...
thanks..
Yea i know bro. The lower the manufacturing process. the lower the safe 24/7 voltage. So i`l keep it at 1.3 max with the stock cooler.Quote:

i have force3d 5850 unlocked with msi bios
I have this card VTX3D Radeon HD5850 HDMI DisplayPort Dual-DVI 1GB , do u think i can use the MSI unlock bios to go past the limit . My limit now on Core in CCC is 775 and mem 1125....
This card http://www.vtx3d.com/products_features.asp?id=38
here's my awesome vantage score i dont know wtf is up im pretty sure it has to do with vantage, because i was getting higher scores before, btw this is with x2 5870s in xfire 1000/1300, i7v 920 at 4.2
http://i41.photobucket.com/albums/e2...creenshots.jpg
its really low for 2x 5870s...
here's mine :

the thing is that just after this, i found out that my memory can stay up untill 1260... :P cause i didn't understood the way to check and stablize them so i put them on low freq...
your cpu is holding you back...
Thats low indeed. HT enabled should help. What driver you use? Are you sure crossfire is enabled, seems like a single card score.Quote:

crossfire is enabled and windows is recognizing both cards, i'm using the beta drivers which i have been for the past month or so. i'm pretty sure its a vantage problem i tried uninstalling and reinstalling which didnt work
i rolled back my drivers to cat 9.10 and same results except i scored at 20k. i disabled xfire and scored 17425 wtf is going on here? a week ago i was scoring 25k+ on stock

I score P22646 in Vantage with my crossfire 5850's at 950/1250, and i7 at 3.8GHz HT enabled, CCC settings are highest quality.
25k+ sounds too high at stock GPU settings. Low 20K's I can possibly believe.Quote:
