Change liquid substrate capacitors to solid ones?
-
Let's see who can shed light on whether it's really possible to replace an aqueous substrate electrolytic capacitor (the normal ones) with the equivalent in farads and voltage but solid substrate electrolytic (solid/solid Japanese) ones, and specifically talking about the VRMs capacitors of the CPU.
I haven't been able to clarify it by browsing, but it has brought me doubts, one that it's not entirely clear that they are interchangeable because of the specific way each type of capacitor responds, and another that the application or use being given to it also influences, and if it's a switched power supply it seems that it can influence quite a bit.
From what I've read those capacitors are doing is removing the "ripples" but as I'm not an electronics expert I have no idea if that can be altered by the differences in response of one capacitor or the other.Why do I want to know this? Well, I've already replaced almost all the capacitors in the VRMs (I would have changed all of them at first), they are well ventilated, and the MOSFETs are also good, but it seems that the overclocking and the voltage I'm giving it plus the fact that I'm stretching the board has been too much, and since I'm asking a lot from the capacitors I thought that if I could replace them with solid ones they would last longer and on top of that it's likely that they would give me a little more frequency according to the theory.
And no, I have no intention of changing the motherboard for the time being ;D
Can any expert shed light…?
Regards.
PD:
Note:
I am not responsible for any problems derived from following these ideas, the motherboard can be rendered irreversibly unusable if more heat than necessary is applied or it can be damaged with the same soldering iron tip. Also, if you look closely, the copper circle where the solder should be attached is tiny.
It is supposed that one should know how to solder "well", on the first try, etc.

yes, you can change them without any problem, as long as you unsolder and solder well without damaging the board, which is not so easy
the improvement is considerable because they do not deteriorate as quickly and can withstand more oc, and they are more stableregards

si, you can change them without any problem, as long as you unsolder and solder well without damaging the board, which is not that easy
…"If you're right…

Yes yes, that's why I wanted to change them to solid ones, but are they completely equivalent? I don't know if people raise doubts to avoid getting their fingers burned or if there is a reason for doubt, they say that the behavior of one and the other are not exactly the same….
Do you have more info that can make me feel more at ease?P.D.; You know what I'm saying? That since I know nothing is going to break, and the most that could happen is that there would be anomalous behavior of the VRMs and that the normal ones would have to be put back in, I'm going to go ahead and put them in.
I'll go look for them and I'll comment later, I have the OC to the tricore half-checked because of these damn inflated capacitors.Regards.

Hello, I'll tell you. The difference lies in the fact that they are smaller and some can better withstand high temperatures. The OC and others do not vary. If you want to remove them because they are broken. It's not a bad idea and if you also put in more capacity. Then if you improve a little the OC capacity. In fact the difference between a value and a deluxe motherboard. From the same manufacturer. It is usually the amount of capacitors and or the heatsinks it mounts.

You can't put capacitors with more capacity, the higher-end boards have more power phases not more capacitance or capacity per phase. Be careful with the sources of information.
If they can withstand the heat better, the solid ones are better of course, that's why they would withstand better an OC of many watts on a board with few power phases. Besides, the ones with aqueous substrate don't break overnight, they lose their values as they degrade and at a certain point they produce failures.

You can put higher capacity ones in. But they have to be the same. Because if not, it wouldn't be worth it. And at asus. You find the same pcb with more capacitors for the same phases. In the high end. I've been repairing motherboards for years, especially 775 on intel and the entire amd range. -
Well, you leave me puzzled...
Now, one immediately becomes curious about the subject and wants to know more about the vrm, but with the time I have left lately, we'll see if I change the capacitors one of these days, I'm fine at 3.2- 3.5 and I never feel like tinkering with it.
Best regards.

If you talk about the VRM of the board, I think the capacitor values are calculated, I'm not sure if it's ideal to change the capacities in a buck converter without more...
-
well, let's clarify something. putting in larger capacitors won't give you more power. that's what voltage and amperage regulators and limiters do. the VRMs. the capacitors are the ones that will filter out any ripple that comes from the power supply. since there are capacitors in front of the regulators and behind them. the ideal thing is to change the ones that are between the power supply and the regulators. since that's where there's the most variation. plus, this way we protect the VRMs from the ripple or electronic noise that destroys them and makes them heat up more than normal. i've been working in electronics since i was very young. even before i got into the computer world. -
I don't know, I haven't studied electronics for a long time, but I do know that the number of capacitors is related to the number of phases and that the ideal characteristics of these are calculated according to the circuit (http://rohmfs.rohm.com/en/products/databook/applinote/ic/power/switching_regulator/capacitor_calculation_appli-e.pdf). Obviously there are margins, but I don't quite understand the advantage of increasing their capacity, assuming that they are already designed with the optimal values.The input capacitor will always have the same signal and the output one unless you apply a very high voltage also, perhaps in the case of an aggressive OC… But speaking of replacing with something more reliable, from electrolytic to solid, I understand that the best thing is to respect the capacity and voltage values, and an ESR and ESL equal to or less.
But I say that I am a bit rusty on the subject
