Thasp Posted October 7, 2005 Posted October 7, 2005 I know DAGF users are the minority here. However, if this can help just one person who is having a problem with vdimm voltage on the DAGF, it'll have served its purpose. You _can_ get up to 3.2v on the DAGF board. It is a pain in the butt, but quite possible. I have cleared the CMOS using the jumper, I have read the FAQs on DFI's homepage, and have tried the latest BIOS(and many others). This problem has persisted for me on my older NF4-DAGF, and my new NF4-DAGF. I read here http://www.dfi-street.com/forum/showthread...87&page=1&pp=15 that there are a few problems with the vdimm voltage which convinced me it isn't just a dagf thing.. or even a The RAM always runs 0.36v lower than what I set i to when I set it above 2.8v. I set it to 3.2v and it showed up as 2.84 in the BIOS. I tried using windows and rebooting and had the same problem. Then I ran a prime95 using the RAM torture rest for 20 minutes. When I rebooted, it showed 3.24-3.25v. I repeated this process to see if it worked, and it did. There is also a second way to fix it. If I do the above and it doesn't work, say I reboot after 20 minutes of using prime95, set to 3.2v and it shows 2.9v, what I do is keep rebooting and checking the BIOS. If at any given time the voltage is less than 0.36 off from what I set it to, this means the voltage is progressively going up with each reboot. About 10 reboots fixes it. With each reboot, the voltage goes up by 0.3-0.5v until it hits what I set it to, and then I am able to run at that voltage stable. I check the BIOS after each reboot to check if it is going up.

Thasp Posted October 20, 2005 Posted October 20, 2005 Found something else: if I unplug the power supply, and hit the power button a few times to completely drain it, the problem resets to how it originally was. The DAGF has no ability to remember what vdimm voltage I gave it, very siimlar to the cold boot problem I linked to above. Perhaps a new BIOS could fix this issue. DFI never emailed me back on this, so I guess I'll have to live with it. Share this post Link to post Share on other sites More sharing options...
learners permit Posted October 25, 2005 Posted October 25, 2005 Sounds like a simple voltmod issue to me. Share this post Link to post Share on other sites More sharing options...
Thasp Posted November 25, 2005 Posted November 25, 2005 What would you suggest, then? I just spent 20 min playing FEAR than 10 priming with high ffts for RAM and the vdimm is still stuck at 2.84 when set to 3.2v. I had a chance to switch PSUs earlier finally to some generic one in another computer with 24 to 20 pin adapter (thought it would perform worse, better, whatever) but the problem continued. I didn't run anything intensive as it was generic but this rules out the PSU as it performed the same(volting 0.4 less) with another.

learners permit Posted November 25, 2005 Posted November 25, 2005 If I had modules that required higher voltage I would assemble the board outside the case and poke around VERY carefully with a multimeter until I found the vdim power supply and a suitable circuit to bridge to for the desired vdim with regards to the current requirements of the modules and the circuit that is to carry their load.. Of course this action will void the manufacturers warranty. Another less risky solution is to replace your memory with some TCCD or modules with lower voltage requirements. I will soon be joining you and purchasing the board your using so I could help with this mod as soon as I can afford to make the move to pcie. The X1800XT is still outta reach for me at this point so it will be some time b4 I can do this. Share this post Link to post Share on other sites More sharing options...
Thasp Posted September 2, 2006 Posted September 2, 2006 JUst for kicks, I tried this with my new DAGF, since I bought one for a server. I never thought to overclock it but I put this RAM in there and tried it anyway.. same thing, I put 3.2, it shows 2.8, and I know it's putting 2.8 because winbond ch5 should boot at ddr400 2-2-2-6 with 3.2.

Thasp Posted September 3, 2006 Posted September 3, 2006 Has anyone had experience with the OCZ voltage booster on this motherboard? I'd like to try it since the DAGF can't go near the 3.2v defined in the BIOS. Share this post Link to post Share on other sites More sharing options...
Gipse Posted September 3, 2006 Posted September 3, 2006 You might want to contact RyderOCZ, I am sure that he will/can help you. I think there is a thread on www.bleedinedge.com too. Gipse Share this post Link to post Share on other sites More sharing options...
