3570k overclocking (throttling)

helping

Posted

Tinkering with a build for someone, and it's actually a really good chip, so far it's looking pretty promising and I've got it running at 4.5Ghz @ 1.2v with next to no vdroop after LLC and 76c on the hottest core.

Problem is the motherboard is a pile of shit. Using a P8Z77-V LX. Terrible board, nobody buy it.

it's seriously limiting the overclock. It's unstable at 4.6Ghz and I can't raise the voltage any more beyond like 1.22v, after a few minutes of running LINPACK or OCCT it begins to throttle down.

Right now it's in an NZXT Phantom 410, and it's got some pretty good air flow. Would adding heat sinks with some thermal adhesive likely fix the issue? Clearance isn't an issue. I assume they're the little black boxy looking thingies.

I believe the heatsinks should be added to the small black chips behind the R68 ferrite inductors.

Yea, I have no idea where to put them since I've never handled a board that didn't already come with sinks. 

 

 

I'm also considering if I should even bother since it's already at ~76c, and I'm not really sure where the 'safe' cutoff is.

I would cut it around 80. My 2500K runs 5GHz/1.5V at around 69C peak. (But that is with an H100i)

I might just leave it alone, since he's going to be moving from an h80i over to air.

aye yo don't be stealing my deadmau5 swagger

Nah, I think I shall mang.

I would cut it off. Personally I hate to have my CPU even at 60C max load (3570K 4.4GHz 1.14V VCore) and 4.5GHz is already a great OC. Plus I wouldn't be comfortable pushing it too much on that board since it doesn't have heat-sinks on the VRM and doesn't seem very high quality.

My Current Build: 

Intel i5 3570K @ 4.4GHz 1.11V, Cooler Master Hyper 212 EVO, Asrock Z77 Extreme4, Corsair Vengeance 8GB 1600MHz, Samsung 840 EVO 250GB, Asus GTX 760 DCII Overclocked, Corsair CX600M

you will be limited by vrm design, not vrm cooling.

 

I would replace that board to something more OC friendly if overclocking is important.

That was the board i originally built my PC with. Now it sits in a closet and actually still somehow works. 10/10 would not buy.

Our Father Birb has taught us with His humble heart and gentle wing the way of the bob. Let us show Him our reverence and follow in His example.

I agree with that. The board is only has 6-phase VRM circuitry. This will severely hold back your overclocking attempts.

Phanteks Enthoo Pro Black | Corsair TX750v2 | ASRock Z97 Extreme4 | Core i5 4670K @ 4.4 GHz @ 1.27V | Corsair H105 | 16GB Patriot Viper 3 PC3-12800 | EVGA GeForce GTX 770 | Axiom Signature III 240GB SSD | WDC 1TB Blue | Hitachi 750GB

I use a 'moron filter' on tech forums. If I don't respond to your post, considered yourself filtered out.

On the mosfets. You dont cool the grey blocks (chokes) at all, whats the point cooling copper wires off :P it's only the mosfets that are being cooled.

If you're throttling just make sure to disable Intel thermal adaptive monitor under the cpu configuration tab. I've seen that thing throttling my 2600K I had at 73° >.>

Marketized as a 6 phase but only 4 are being supplied to the vcore. If you haven't noticed many overclocking boards like you see from MSI z87 mpower max orsomething is actually a 5 phase design. Source: http://www.sinhardware.com/images/vrmlist.png

4 phases shouldn't limit you, I've seen a livestream a guy clocking his i5 to 6.5GHz under ln2 with that asrock z77 extreme4 (also 4+0 design)
