What is vdroop mod

What do you think about the capacitors to be added behind the socket? Funny thing is I benched with that motherboard and I did not have vDroop so I am a bit bemused that your one does. OK give me a few minutes and I will see what I can pull out from my old hard drives about volt mods that I did to that board. Please show me a CPUz screen with your P5Q system at idle and under load I want to see the volt drop - my notes say I had no volt drop with this board.

That is not the same thing. If you go into your bios and look what the vcore is at, then boot into windows and use a proggie and see what it's at there. If there's a big difference, like. I havn't tried it nor do i know much about it, that's just what i've read. First, let me explain vdroop.

In the voltage menu of the BIOS, you will probably notice thats some voltages are higher there than they are reporting inside windows. But due to the nature of electrical transport, in Windows, the actual voltage the CPU is getting is much lower, like 1.

The vdroop would be. Some vdroop mods may require soldering, others could requires just a number 2 pencil. But be warned, every board and part has a diff thing to mod, so info on the web is specific to that exact board. No, vdroop mods are not necessary for functionality of 4gigs of RAM and has nothing to do with it. As what I can see it needs to be done when you have 4 gb or more? Is that correct? Only "necessary" if you're overclocking your CPU by a good amount.

Report Post. Graphite is a good conductor of electricity and so by vdroop, you are basically shorting or bypassing a resistor in the motherboard by pencil mod to get lesser difference between idle and load voltages for CPU. This voltage drop is actually meant to protect your CPU.

It's like the stunts; nice to see, but damn too risky to do, and the results aren't worth the risks undertaken. I know of people killing their motherboards due to stray graphite. If you prefer not to take unnecessary risks, and end up with dead components, leave out pencil mods or vdroop mods. I have my QX at 2.

Yeah the vdroop mod is nt needed always. I only did it to help stabilize 3. Key word "help", other things had to be done too, lapping, and voltage optimization. Yeah that's right , and the correct combination that provides stable ocing at max possible settings isn't something that's found in a few hours; we'll require trial or error with several hours of testing and benchmarking to do that, but still, to tell the truth, you can have a better sleep knowing that you haven't done pencil mod, that's all.

Apr Does anyone recommend this or not. And yes there is one, or maybee 2 bad caps. I dont know which voltage rail they belong, but to increase stability this must be fixed. Maybe this cause these "all of the sudden pc turn offs" with all my 4 P4CE dlx boards. It was random, most time when I connect a usb device the pc turns immediately off and sometimes dont turn one for some time. Unplug the power cable of the psu and wait for 10 minutes solved the problem the most time.

I never thought this was a psu problem because I thought Enermax was a very good psu manufacturer. I thought this was the common known "USB latchup" problem with or in the southbridge.

Well I will try to make a complete recap of the psu and try it again later. I will ask the questions relating to this topic in another thread. Attached Images Ok guys, I just repaired my Enermax Liberty psu and put a new bios battery on the board. I checked the new battery before, it has 3,3 V. The old one had 2,87 V.

The board still boots with "new CPU installed" message. Any ideas? Meanwhile OC ability get a little bit better due to the psu recapping. Mostly the 12V and 3,3 V line got more stable and stay stable under heavy load, but also in idle or Bios. The only problem now is the "new CPU installed" issue. Can anybody help? Edit: I turn off the pc ans switched the psu off, after 2 min psu on and boot.

Wtf, I just put a new 3,3V Bat on it Edit2: I put the new 3,3 V bat out of the board and measured it. It has 3,21 V Where gone 0,09 V in 2 minutes Save them by your self in the BIOS screen. There is NO such issue. Problems gone! Now I go back to my old rig setup step by step and try to find the error!

Greets TCC. Ok, problem solved.
