Re: Undetected Good RAM Module HELP!
acceptable tolerances? The RAM circuit on the mobo degraded below what that module's tolerances will work with ? hmmmm .. sirs, how can we put it in layman's terms? is there any simple ways to check those tolerances that a certain module can handle?? by the ywa, PCBONEZ, i have a private message to you..Last edited by cmosbios; 04-15-2011, 10:56 PM.Leave a comment:

Re: Board do not start - burned voltage regulator?
what is it look like? i mean the regulator you are saying. isnt it that Mosfets are also regulators?Leave a comment:

Re: Undetected Good RAM Module HELP!
actually, i have 2 ram modules seated on that motherboard. with same frequency and type, almost identical but different brand. then one day, PC hanged. I rebooted and then there it was... black screen .. no beeps.. what i did is removed one RAM at a time and have the system boot with a single RAM. With the other one RAM, the PC booted. So one RAM is Good. To check the other RAM, I removed the good one and replaced by the other RAM (previously working on this board) on the same slot where the other one seated. tried all the slots (four of them)...Leave a comment:

Re: CMOS battery life
PCBONEZ, can you please give us an idea of basic BIOS circuit, I mean NOT the circuit inside the BIOS, but the circuit behind the BIOS system on a motherboard. Some kinda diagram and its basic components.Leave a comment:

like they always say, do not try to fix when it is not broken. try different working RAM first that the board supports ...Leave a comment:

Re: Undetected Good RAM Module HELP!
Digge, tried swapping from slot to slot and still no boot! NO BIOS beeps! Fan turns. I tried the other RAM and it booted up. At first, perhaps the RAM itself is faulty so I had it seated on different motherboard and the RAM worked with it smoothly.. and that means the RAM module is working fine.. The culprit motherboard has different RAM seated on it by now, and its working well with the motherboard .. but whenever I try to put in different RAM like the one I said .. same problem arises.. it stop booting .. voltage problem? caps? psu load? how...Leave a comment:

Re: Testing VRMs on A7N8x rev 2
set your ohmmeter to higher range and check again. and it should get 0 very low resistance. to accurately check the component being tested remove it from the circuit board and do a FET regulator test.Leave a comment:

Undetected Good RAM Module HELP!
I have 2 Good RAMs on my mboard. Suddenly, the other one stopped functioning and now been removed so that I can check if its still functioning when slotted to different motherboard that support that kind of RAM. And so I did, and the RAM works smoothly with different board (same model from the previous one). What do you think the reason that the other board couldn't have it functioned? Would it be a voltage problem? I left the other RAM still seated on its slot and functioning well. what do you think is the problem and what is the possible solution? -
Re: Testing VRMs
@Akor
you mean if I test the VRM, test each mosfet(VR) inputs and outputs? I am not sure if you are referring to VRM block (2 mosfets, ic driver, pwm) input and output circuit tests. what i know about the VRM is NOT the mosfet itself but the circuit. please enlighten me.Leave a comment:

well you can use hot air rework station for reflow.Leave a comment:
