Apologies for waking up this thread. I just wanted to note that the motherboard was faulty. It has been repaired by DFI (according to the report, they changed the chipset and some ICs). For the moment it seems to work fine. I do not want to rely on it too much, though...

Well, I think CnQ is effectively disabled when I run two instances of Prime95. If need be, I will turn it off completely to see if it changes anything. Thank you very much for the multiplier tables. Now I see that my second theory was right, and the MCV/L value in the BIOS means some fixed dividers. (200 -> CPU/10, 266 -> CPU/8, 333 -> CPU/6, 400 -> CPU/5 for my CPU multiplier of x10). It is interesting that the memory can run 400Mhz fine when there's no overclock, but it fails to run at the same speed in an overclocked situation.

Thank you for your suggestion, I could try that. OCZ says 2.1V +/- 5% is the limit for this model, though, for warranty purposes. Even with warranty put aside, it tells me there's something wrong here, and it may not be just the RAM. I think my initial setup also supports this theory (initial setup where I had no overclock and I could get the memory to run at 400Mhz with 2.1V without any problems). I just found out a thread in OCZ support forums that mentions about problems with their 2GB PC2-6400 kits and AM2. It does not refer to DFI specifically but I see some users not being able to run these modules to the full capacity. The thread is here: http://www.bleedinedge.com/forum/showthread.php?t=22133 In another official thread from OCZ, it is mentioned that the BIOS should have NVMM version 4.062.19. I do not know if it means anything in this case, but just wanted to point that out.

The system is in the sig (#2). Here's what I figured out so far with respect to the capabilities of the components: CPU MAX: 2.6Ghz HTT MAX: 260Mhz (yes, I tried to go above that but it loses stability around 270 (using x9 as CPU multiplier, so I think 260Mhz for HTT is the max for my board) Memory MAX: 440Mhz My initial settings were HTT: 200Mhz HTT Mult: x5 CPU Mult: x10 MCV/L: 400Mhz Notes: 1- Timings manually set to 4-5-4-15 2- CPU voltage set to 1.45V (def 1.35V) 3- DIMM voltage set to 2.10V (def 1.85V) 4- HTT voltage set to 1.35V (def 1.30V) CPU-Z reports that the memory is running at 400Mhz, 4-5-4-15-22-2T To understand how MCV/L works, I set the system as follows (yes, I have CnQ enabled, and I would like to keep it if possible): HTT speed: 260Mhz HTT Mult: x4 CPU Mult: x10 MCV/L: 200Mhz In this case, CPU-Z reports that the memory runs at 261Mhz (idle, CPU/5) and 261 Mhz (100% usage, CPU/10). If I change the settings to HTT speed: 260Mhz HTT Mult: x4 CPU Mult: x10 MCV/L: 266Mhz the memory runs at 261Mhz (idle, CPU/5) and 326 Mhz (100% usage, CPU/8). BTW, these settings are what the system is running on at the moment. If I try to set the MCV/L to 333 or 400 Mhz in the BIOS without changing anything else, the system does not start. I want to ask what that setting actually is. I had two ideas: 1- Judging by the wording, it should be some limit on memory speed, even though the actual speed is adjusted automatically. However, getting the memory to run at 326Mhz while this "limit" is set to 266Mhz means that this is not true. 2- If this setting implements some fixed divider (i.e. 200Mhz means 1:1, 266Mhz means 4:3 etc), I should be able to set this in the BIOS to 333 Mhz and get it working. However, it does not work as I expected. I tried the following setup: HTT speed: 240Mhz HTT Mult: x4 CPU Mult: x10 MCV/L: 333Mhz Now the system boots and the memory runs at 240Mhz (idle, CPU/5) and 402 Mhz (100% usage, CPU/6). This setup, however, is not stable. It boots but Prime95 fails in a few minutes (interestingly, when Prime95 fails and I reboot, the system DOES NOT BOOT. I have to hold the INSERT key and lower the HTT speed even more to get it working. Strange...). I know that the CPU handles this load fine, as well as the memory (402 Mhz is nearly the stock speed). The only explanation I have at the moment is that MCV/L setting does something that I cannot figure out. Thanks in advance for helping me with this.

I tried those steps once more but it did not help (I had tried them a few times over the last 18 months that I owned this mobo). Those instructions assume the machine does not boot at all and once you get it working, you can actually see something on the screen and make necessary changes. In my case, the machine POSTs fine, and it boots into windows. I can even go into the BIOS menu by pressing DEL. I do not see what I am doing but I can shutdown the machine from the windows (Windows-U-U) or I can get out of the BIOS menu (ESC-Y-ENTER). Is it possible that there's some video card related setting that needs to be set but it is set to some unsuitable default so that the machine is hosed? If this is the case, I can put in my PCI video card, set the setting and put back the PCI-E card. Thanks in advance.

I have this Ultra-D mobo since the beginning of 2005 (I am one of the early adopters). Except for a very short while, I have not been able to get the PCI-E slots on this mobo working. I will give it one more chance by asking here, with the hope that someone can help me. Otherwise, I am planning to scrap (*1) this mobo. If I use a PCI-E video card (*2), I do not get a video. The last diagnostic LED remains lit and I get one long, two short beeps. I know that the machine boots into windows since I can shut it down with a key sequence (Windows-U-U), but I can't see anything at all. I tried both the 8x8 and 16x2 positions of the PCI-E jumpers, it does not make a difference. (*3) If I pull out the PCI-E card and put in my old Matrox PCI card, everything is fine. Any ideas? Thanks in advance. (*1) A friend of mine needs a lightweight server so if I cannot get this working, I will use the matrox card and build the server for him. (*2) ANY PCI-E card. I tried this with GeForce 6600GT, 6800GT, and some others. The most recent one I tried is a Sapphire X1300pro. None of them worked except the 6800gt and it worked only for a month or two. One day, after a reboot, that also stopped working. And yes, I verified that these cards are functional by using them in other machines that I have used. (*3) If I put the video card in the top slot, the detection process takes a few more seconds. The end result, however, is the same.

It was a GA-K8NF-9 board.

DFI USA (after talking to HQ in Taiwan) replied to me saying this is not supported with the current BIOS. I had built the media center computer for a friend and he wanted to use it as soon as possible. To solve this problem as soon as possible, I visited a local dealer and checked the manuals of all mobos to see which ones had the option. Finally, I switched to a Gigabyte board and all is well now. DFI USA also said that they would ask the HQ to rush a BIOS with this feature supported. I hope it will help others.

Well, I checked it again and it is not there. Maybe you were thinking of another motherboard. Or, if you know of a certain BIOS version that has this, I would appreciate a pointer to that. I have read several posts about NF4 Lanparty UT and STR, but the consensus is that it does not work and should not be used. I built other Media PCs with different mobos and I got it working all the time. Therefore I am inclined to think that this is a BIOS problem, and I am hoping that it is fixed as soon as possible. I can't just believe that "it does not work, use S1 or some other mobo" is the formal approach from DFI. I am saying a problem, since even if I put the OS into S3 and push the power button to resume, it restarts rather than resumes.

1. Yes, and yes. 2. Yes. 3. I am not sure if my mobo has this option. Where should it be in the NF4 BIOS? Thanks for your help.

I tried those but they did not help. Is there anything else to set (maybe a setting in the BIOS)? More than that, I can put the machine to S3 via remote but if I try to wake up by pushing the power button, the machine just reboots. I am not sure if this by design or not. Any ideas? Thanks in advance.

Hi all, I have built a MCE 2005 box and I was hoping to be able to put the machine to standby and wake up using the media center remote. Putting to S3 stand-by is no problem but I cannot make it wake up from that state. I searched the forums and could not find about this issue. I apologize in advance if I missed any existins answers. Thank you in advance for your attention.
