Whoa! now thats one sweet rig. Did you check out the io on the disks, just awsome.

Just wondering if you ever tried 705 or 711 offical BIOS. At one time I had a 3200 in my nF3 UltraD with C19 and had a heck of a time with it. My Sandy 3700 and Opteron 146 however were fine with C19. Just a thought but you might want to try one of the official BIOS, do a proper CMOS clear and see if things improve for ya.

There is a known cold boot issue, with some of the earlier bios for this board. What is your current BIOS version?

Moulinex, I can tell you from my own experience you will have big problems getting stability with 4X512Mb, and mixed memory. The only way I ever got this to work on this board, was with 4 matched pairs of the same memory, and even then, depending on what bank a particular stick was in would sometimes throw things off. Over clocking in this configuration, was well interesting to say the least... If you press on see this entry in the OCDB which may help. http://www.dfi-street.com/forum/showpost.p...99&postcount=60 You must also run 2T. The other option which I eventually went with was 2X1024 which is really sweet, and you can get some good deals on 2X1024 right now which is a bonus. Good Luck!

Try this guide dude, hopefully it will get U started http://i4memory.com/showthread.php?t=327

petergiro, do you have SATA drives connected, and to which ports? If you could add this to your sig it would also be helpful. Thanks,

Check this post, which describes this a bit. It looks easier than it is actually. There is very little room to get a probe in on one of the torroids without shorting things out, which is not good if you know what I mean. :mad: http://www.dfi-street.com/forum/showthread...ment#post197338 http://www.rebelshavenforum.com/sisubb/ult...c;f=31;t=000195 To do this you will need to get your hands on a 3M micro probe-it clip on test lead, or something equivalant. I found mine at a local electronics supply I use here. They have a tiny wire gripper that retracts from inside the tip of the probe, that grips the lead without shorting everything out. Then you can measure vcore safely.

That pretty much seals it, your PSU is at fault here. Kudos to you for sticking with it and methodically narrowing down exactly what the the problem is. This has been a good thread, that I think I will need to bookmark for future reference. Once you get your new PSU enjoy your new system. My nF3 Ultra-D is about a year old and although I am handing it down to my oldest, I will miss it as it has been a great system. Cheers!

I think what you are looking for is in the mainboard manual for this board on page 51. The PWR-LED pins will supply power to the led when the power is on. You should be able to just push the connector onto the connector pins 2 & 4 and it should work. Hope this helps... http://www.dfi.com.tw/Upload/Manual/lp%20u...081000414-r.pdf

Thats what I suspected, the C19 bios does not enable the CPU Voltage adjust in the BIOS. I also had to set my CPU Volts quite high (1.575) just to get 1.42v vcore using a multimeter. Its a pain, I have learned to live with it. It looks like your on your way though so that is good news, and luck As far as the SATA thing goes, search the tweeks sticky. There are some really good threads there regarding this. Its tricky, but if you leave your SATA until very last when you are done tweeking you can get it to work. Overclocking after that though can be interesting.

Q: What BIOS version are you using, when you see "CPU Voltage adjusting = +0.1v" greyd out? Q: do you have sata RAID drives connected and configured? I had a few thoughts on this, but need to know what BIOS U are using - Possibly you have the core voltage set too high and CPU Voltage adjust is not available to avoid seriously overvolting. Try lowering core voltage, and then adding CPU Voltage adjust. - The BIOS version you are using does not have this feature. For example C19 does not have CPU Voltage adjust in geni bios. You can only adjust the core voltage. BTW, is CPUz reports 1.5v that should be lots of volts unless you are seriously overclocking. Assuming you are still trying to get stock stable for now I would stay with this at this stage until you figure out where the instability might be. Later on try increasing vcore once you get some of these things sorted out to your liking. Also watch your temps, and if you have a multimeter measure your vcore instead of using bios or cpuz which are whak.

Hmmmm, before you give up on those sticks, you should know this is pretty common with C19 on the nF3 Ultra-D. C19 is very picky, and there are few settings that need to be manually set in the bios before you will get anywhere. Auto is just not an option like on nF4. Here are a few suggestions that might get you started: First off use the following procedure to do a proper CMOS clear. I would reccomend that you stick with C19 as it works best with opteron, with both sticks in the orange slots. http://www.dfi-street.com/forum/showthread...lear#post317242 Also a few other things to be aware of... This board under-volts VCORE (the CPU core voltage), if you are not using +0.x voltage adjust. If you are it overvolts. Check the table in the tweeks sticky attached, and use the tables to set the proper VCORE. When I started with my 3000+ venice I used the following which gives about 1.4v VCORE on my board. CPU VID Control = 1.425v CPU Voltage adjusting = +0.1v http://www.dfi-street.com/forum/showthread.php?t=17498 - Also check your vdimm as it defaults to 2.6v which in many cases is too low. Bump it up to 2.7v and see if things improve. - Make sure your SATA drives are on ports 3 or 4. The other SATA drive ports (1&2) are not locked. - Set your AGP OverClock in MHz = 67 to lock the SATA bus. Otherwise the SATA bus is unlocked. You will also need to find some stable stock settings for those sticks, or read the spd and other timings using A64 tweeker. I would suggest looking in the stock settings database or in the overclocking database (OCDB). Start by setting the SPD manually, in the geni BIOS and test only with memtest86 on a bootable CDROM. Don't try and get into windows yet until you get memtest stable. Next start coding the following in pairs in this order. DDR DQ drive strength = 50% reduction DRAM Bank Interleaving = Enabled Max Asynchronous latency = 8ns Read Preamble = 6ns Row Refresh time (Trfc) = 16 Row cycle time (Trc) = 12 If you follow this and you still have errors in memtest, or cannot boot into windows then it may be more likely you have a bad stick.

Thats correct the Vantec Iceberq does not report its RPM to the BIOS. BTW I think we are drifting here, lets try and stay on topic...

You can use this cooler (CCB-A1C) Iceberq on the nF3 Ultra-D without modification. It does not have the fancy leds, or a fan sense leads but it works and it quiet http://www.newegg.com/Product/Product.asp?...N82E16835110103
