Set VCore Voltage Too High During Overclock Did I Do Damage?

[Rroff]

Are any of the components on the MB? I really hope that it is the CPU because the MB has the highest resale value (Asus Rampage V Extreme). I will be looking for a replacement cheap CPU on eBay but I can't replace the MB as the cheapest x99 is over £100.



Don't have to do that, I have a second Win 10 install on a separate SSD where I test my software so will try that and report back.

Motherboard in theory shouldn't let you set voltage values it can't handle - I'd imagine chances of doing damage to the board in this scenario are low.

Update: Got a replacement CPU and all works good now.

But I have a question...

Is it possible to set a max vcore on the motherboard - I know it's motherboard-dependent, but it that even a thing? Obviously I'm scared to mess up again.

and...

Is overclocking on auto vcore, stress testing and monitoring the voltage it's taking, then inputting that voltage into manual vcore a good idea?

For example: 4.2GHz, auto vcore, stress test shows CPU is taking 1.26v... input 1.26v into manual vcore and expect stability? Then maybe lower from there incrementally.

My approach has always been to start lower than the auto voltage. Yes, you can get a fairly good sense by looking at what the voltage is on auto during testing but there will be a lot of other 'auto' things at play. So, it's hard to get a very good sense of the parameters you have to work with. Generally, I would look at what people are running stable at for a particular frequency for that processor and board and work from there. Boards differ but really, when you set a manual vcore then that is also the max vcore. Instability issues don't just arise because the voltage is too low but also because the voltage delivery to the CPU is either too low or too high in a short burst. This is what LLC fixes. If you are running a low vcore then you are more exposed to under delivery when the CPU suddenly needs more voltage. A lower auto vcore setting will typically require a higher LLC setting.

OK, apologies, I see what you are asking. In effect, 'can you set something that stops you entering too high a vcore in the BIOS?' Nope, I've not seen that.

One thing you could condition yourself to do is use 'page up/page down' for settings in small increments and don't allow yourself to type in the settings.
