[RESOLVED] HOOK-UP THE DANG P4/4PIN CONN>> VCore-Problem with La

[nagybalfasz_b]

I have a new DFI Lanparty NF3 UT 250GB mainboard and a 3400+ Newcastle CPU. The strange thing with the two is that the processor crashes all the time (strangely as if the video card would crash it produces a picture full of rectangles) if I set a VCore higher than 1.475 V. This is totally strange to me, cause 1.475 V isn´t even the standard voltage for the CPU. The strangest thing is, that I thought the problem was unique for that single CPU, but after changing the processor to another 3400+ it produced the same problems.

I´m using the Corsair Hydrocool watercooler, and the processor is totally stable at 2520 MHz. So how can it be, that the processor can´t handle 1.5 V upwards even at 2400 MHz, but is able to run at over 2500 with 1.475?

wat is the multi set to, if its auto then it would be adjusting itself. set the VID multi to anything but auto. for 1.65v, its 1.5 and 110%

It doesn´t matter if I only set the VID to something above 1.5 V or that I get a VCore of more than 1.5V with the addition of VID and VID multi it produces the same result. Tha strange thing is, that the system doesn´t crash, only the picture. So I can restart the Windows normally without having a right picture (only these rectangles overall) with the right combination of buttons (Windows-button + one up + Enter + "n" for Restart (German Windows XP)). So it seems that the video card produces the problem. But if I set the VCore under 1.5V all these problems are gone. So what has the VCore to do with the picture??

What PSU do you have?

A good one! Leadman 400W. The PSU can´t be the reason, because I tried it without all the extra HDDs and PCI-cards with the same result (and beside that I tried another PSU with 450W).

The video card can´t be the reason for it, because I tried two different cards with the same result of crashing the video signal (but the system itself doesn´t crash as I said).

...when we know all the what it is nots and none of the what it is.

 

I have seen a couple of people using Radeons that do similar to yours that added a switch to delay turn on of the Video card because of the massive amount of 12V needed to crank the card and computer and the few I have seen do so had much stouter power supplies than you said you tested with.

 

Suggest you RMA the board back to where you bought it from and get on with your computering because your problem is so strange there is not going to be a hack for it that will crank it up.

 

Sincerely, RGone...

Hmm, I noticed one strange thing in the PC health status in BIOS:

It says that the PSU only provides 10,66V instead of the 12V. I really don´t trust in the numbers in the PC health status, but this is a difference, which would be horrible, if that would be true.

Strangely I had no problems at all with this PSU in the past with other systems (eg my last system: Athlon XP 2600, Radeon 9800 Pro, 3 HDDs, 2 DVD-drives).

[bldegle2]

the actual outputs with a multimeter, the low 12 volt rail is your culprit, the vid card you are using runs with a 12v molex...................................with voltages in the 10.5 range, i can see all sorts of weird behavior.

 

if what you say is true with the other parts working fine in other setups, then i would have to say the voltage regulator or some other part is not allowing the full 12v to course through the MB, and it just may need exchanging.

 

check the bios voltage readout with the other PS, if the 12v line is low like the other one, motherboard for sure. i would be checking the readouts with each PS running in the system, just check it at a four pin molex, at least you will get the 12/5 from that, the 3.3 is metered from the FAT orange wire in the 20pin MB power feed.

I checked my 2nd PSU now (a TSP 420W) with pretty much the same result. The PC health status says 10.66-10.98V.

As I can´t boot into Windows with the RAM-voltage higher than 2.8V, although I had no problem at all in the past to use the RAMs with 2.9V (that was the max the NF7 could provide) I´m really beginning to believe, that there is something wrong with the mainboard

Do you have the 4pin connector hooked up to the mainboard. As far as your PSU handling other systems the A64 really draws a lot of voltage, so the requirments are greater.

 

Also try clearing CMOS & hit LOAD OPTIMIZED DEFAULTS. Then go back in & set every thing back up.

 

Now you do know that you have to set voltages two times in bios.

 

 

Enter bios - set voltages- save & exit - enter bios - save & exit. This has to be done before the voltages can take effect.

 

Try raising AGP & CHIPSET voltages also with CPU voltage.

 

You do have COOL&QUITE dissabled right.

What do you mean to the main board? Where would it go? I am having the SAME problem with a low 12v rail.. I have an antec true480 and it was solid as a rock on my other system (AXP).. During prime it dips to 9.72.. This isn't right..

 

I have the 12v molex from the PSU (black color) connected another molex that goes to my gfx card and fan controller.. Is this wrong? I had the same exact setup in my other mobo..
