I'm using the Biostar TA790GX 128mb, and unlocking the cores couldn't be easier. Just make sure you're using the January 09 bios and not the June 09 one.

thlnk3r... Has anybody had any issues with their NIC on the UD4P? I first noticed I couldn't reply to PM's on a torrent tracker. When I checked the error console in Firefox there was a ton of problems. I cleared the errors and checked different sites. There's definitely s problem. I've tried just about everything including a clean install of XP. I'm using sp3.

Is it possible to fry the NIC or damage it by overclocking, changing voltages on the NB VID? I'm pretty sure I've had this issue since before I even unlocked all the cores but it's hard to tell. I also cleared the CMOS but there's still a problem. Should I just install a new NIC card and see what happens? Thanks!

While the new bios adds "support" for the new CPUs in that it will recognize it, it still works without it. The bios just reads it as unknown AMD processor :P

I believe that they disabled ACC in the new bios, but I'm going on only what I've read, which is why I'm using the Jan bios. Here's a link to it btw:
http://www.biostar-usa.com/app/en-us...s.php?S_ID=377 (my mobo shipped w/Jan bios)

I plan to keep tweaking the settings in the days to come, I've OC'd only through the multiplier so far, so I'll figure out where my wall is there before I touch the bus. This Katana 3 is bananas, though. 26-29C idle, 40C prime95 This Biostar bios is somewhat limited, but it's getting the job done (also seems like it undervolts considerably ) I'd kill for an asus bios right about now

Contagion, very nicely done +1

JMT668, nice overclock. Is it completely stable?

RendoR, I have not heard of any NIC issues with the UD4P and google didn't turn up anything when I performed a search. It's quite possible that overclocking did cause that component to fail or to become faulty. Does it show up in the device manager? Are there any errors in the event viewer?

Good luck

Just fiddeling around now, this chip will do 4160MHz + on 1.5vcore (see earlier post)

Im just trying to find a "comfort overclock" on this mobo before ill switch to a AM3 mobo later this week, i try now sub 1.4vcore and see if i can push even closer to 3.9GHz for 24/7 use.

Still on aircooling,using TRUE + 12cm Pabst@1840rpm
included hwmonitor to the dual superpi32M pic.

thlnk3r... My NIC shows up fine in the device manager and I did update the driver with the latest one straight from Realtek. There are no errors in he Event viewer that "appear" to be related to this problem. I'm getting an absurd amount of errors though in Firefox's error console though..

Just want to let everyone know something. The UD4P does have a hardware problem with the DIM voltage. The default voltage is 1.95v NOT 1.80v so if you have RAM that requires low voltage, you cannot lower the volts. I confirmed this with the manufacturer. That's why when I gave my RAM a +.200 bump, it didn't appear to change anything. So if you require 2.0v there's no need to mess with the settings. Just be aware of this when purchasing RAM and making adjustments.

One last question. Can you "wear out" a Bios by going into it too much? Not flashing it too much, just using it in general. Sometimes I have trouble accessing it now and if you hold the delete button down too long it makes a sound like a miniature jack hammer. That can't be good for it.
