is this safe on a 4-pin?

Recommended Posts

Posted · Original PosterOP

so i overclocked my X4 955 (3.6ghz at 1.5v) and it's been stable.

 

however while discussing it in a Discord server someone pointed out that this is dangerous because my board only has one 4-pin and the connector could melt or something...

 

is this safe to do?

Hmm... I don't see why it would melt, the worst that can happen is that your CPU won't get enough power. I don't think you can draw more than 75W out of a 4pin, at least not if your motherboard respects ATX specifications. I could be wrong but from what I've read I think you're ok.


...is there a question here? 🤔

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

I’m guessing OP games on one of them and uses the other for NVENC or something. On newer titles the 1050 should be faster but on older titles or games with good SLi support the 690 would perform quite well.

the board supports 140W cpu's so...

It depends on how much current the CPU draws from the 4-pin connector. From what I can gather on the interwebs, the 4-pin power should safely, if built properly, carry 8 amps per 12+V line, which means 96W between the two, or 192W total.

i should be fine then considering stock TDP is 125W and stock voltage is 1.35... it's not that much higher than stock.

stock is 3.2 so it's not that extreme.

GTX 690 runs my main screen and the 1050 runs my side displays. it's for 2 reasons. 1 to save vram ont he 690 and 2 because the 690 has limited outputs in SLI mode.

That's the TDP, not the power draw. Also the CPU takes power through the 24pin connector too. The 4pin or 8pin is auxiliary.

If there isn't any warning on the motherboard that specifically says which CPUs not to use, then I don't imagine it shouldn't be a problem using the CPU and overclocking it a bit. Also remember that overclocking, at least if you're only changing clock speeds, is a linear increase in power. So if you bump up the clock speed by 5%, that bumps up the power by 5%.

nope. the 690 is 2 680's on one card, and even a 680 is faster than a 1050. in SLI supported games the 690 is a LOT faster.

Shouldn't be a Problem for CPU and VRM.

However the 4pin Connector it is.

 

With 6A its 144W, with 9A its 216W maximum. That is really really close. 

And I'd assume that the CPU might be around the 200W Ballpark, maybe even 250W...

 

The old Phenoms can deal with rather high voltages and 1,5V is something you see for example on a 1800X at Stock...

 

The Russians from IXBT Labs IIRC did a Review of that a long long time ago, sadly the Site went down and I don't have a Backup either. It was an awesome Article, even 10 Year later. And I really really loved to link it...

Run some IBT or whatever for a bit and touch it? Should be fine though

 

*edit*

These and pretty much every other connector can go way over spec safely btw

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

i changed the multiplier so.... from 16 to 18. what does that equal to?

If you didn't change the base clock speed, that's 12.5%

so assuming the 125W is correct then it's 140W now. that makes total sense because if i go any higher it turns off immediately when it tries to load Windows, and the board only supports up to 140W.

so if we go by 140W then according to this it should be safe then?

As far as current carrying capacity of the wires, yes.

that was my main issue. thanks!

I'm not sure what else the rest of the system can handle.

i'm not that concerned about it. if the board dies it's very cheap to replace. i was more worried about the wires melting.
