UnOfficial Asus Rampage II Extreme Thread

[affiliate13]

I just tried changing the BCLK a little bit ago and ran into a problem.

When I changed it to about 215 and upped the CPU voltage to about 1.55 my top most 5870 (which my Display port is usually plugged into) failed to respond..Wouldn't show the bios or anything. I had to plug the display into the bottom 5870 to get video.

When I went back to the bios and reset to the factory default I could then again plug my display into the top card...but I had to go back into the ATI CCC interface and re-enable Crossfire.

I can use the SINGLE bottom 5870 with a 4.6 ghz overclock without issue...but obviously I want Crossfire enabled.

When I try for really high speeds, something is messing with my PCI-E bus I'm assuming.

Any ideas?

IOH and PCIe voltage might need a bump, i used a little more to get 4.55Ghz stable on my cards, might not be the same issue though.

Hi mates,

I'm having a bit of trouble here,
my Internet provider shuts me down (I have to phone in each time)
claiming my Rampage II Extreme spams mac adresses...!?!

How do I solve this?
Is this common/has it happen to anyone else?

Help would be greatly appreciated!!!

Not happened on mine, are you using a router or a modem?
If a router, does it happen with both LAN ports and do your ISP have a log you can compare to your windows event log? Might be something there to explain it.

Looks good, how hot does that heatsink get under load? I don' think the Vtt daughter board is overheating, as the system remains stable under constant load.

I am pretty sure it's a bad BIOS issue. Weird thing is Trinity is still getting problems on 1504.

No sure, i am waiting for more parts, always more parts , ill stick a probe on it later in the week.

Could one of the PSU rails be overloaded, or possibly try with one stick of RAM see if that makes any difference. Not ideal i know but possibly worth a shot?
