DFI Voltages

post #1 of 4
Thread Starter 
OK, so everything is finally going pretty swell with my 3800+ overcolck except for some of the voltage details. First, I have a question. In the BIOS section that has where you can set the voltages there's also a part that shows you the current voltage draw at that time. On my RAM, no matter what I set the voltage to, it would be consistently pulling .05 volts more. I am up all the way to 3.24 volts and finally the DRAM voltage is exactly 3.24 volts at the BIOS screen. My questions are many. First, should I even be this high. All the reviews of my RAM say it can handle it, and I have two 80mm fans blowing on the modules and they are warmto the touch but never hot. (Even when the computer hangs.) Second, if it wants 3.24 volts at BIOS, should I go even higher so it can have more voltage during gameplay. I ask this because consistently while playing Civ 4 for about a half hour, the whole system just locks up.

Also, I have an option for LDT Bus Voltage. It's set at 1.21 but at the BIOS screen it's drawing 1.23. I don't even know what this is, but should I set the voltage so it keeps up?

My CPU core voltage is fine. I have it set to 1.425 and it never draws above 1.4.

My NB Voltage is set to 1.21 but there is no measurement telling what it is currently running. Does this need to be upped to keep up with the RAM? There's two NB settings: NB analog, and NB core. Both are at 1.21.

My overclock is to 2.55 (255x10.) My Idle temp is usually around 31 and my load temp rarely goes over 41 so I'm fairly certain that it has nothing to do with the CPU at this point.

PS, my northbridge and GPU are water cooled while my ram has the two custom fan setup cooling it full time. Temps are really not a problem.

Again, in case it's not clear, my system is hanging during gameplay: total freeze and sometimes a high pitched squeal comes out of the speakers. Any help would be really appreciated.

OK OK. How can your cpu be stable if it does hard locks. Has it passes Prime95 for serveral hours?

Those voltage fluctuations are fine but concerning your ram i personnally wouldnt go over 2.9v.

To start off with we all know DFI's are picky. So to start off with make sure you have plugged the molex and floppy connector into the board. Then return everything to stock and run MEMTEST overnight and check for errors. If any errors turn up it is likely to be dodgy timings.

If no errors are produced then move on to overclocking. Try not to exceed 2.9v and if the ram cant handle it put it on a divider!

I am running a divider. I was running 180 before and I recently tried 166. With both I checked (only in BIOS so as not to fry the RAM) and I have to go all the way up to 3.4 volts before the RAM finally settles at 3.37. I'm just curious if the RAM will basically take all that it can get (to a certain point) or is this the draw that it needs/wants?

Also, forgot to mention that my HTT is x3 and my timings are at 3-3-3-8. With no overclock this RAM runs absolutely fine at 2.5-3-3-7.

As to the CPU, I obviously can't say definitively that it's stable. I'm just saying that I get the feeling it's something else. Which is of course why I'm asking here.

You dont have to worry about the ram volts being slightly off, thats fine. Put a massive divider on your ram and this way you can start overclocking the cpu without the ram being any issue. Once you find the max speed for your cpu then lower your cpu and multi and try to find the max of ur ram. Then combine it to get you a proper overclock.
