2500K @ 4.6GHz using 1.35v + 0.05v

OCCT runs stable for 24rs and shows:

Temps Min 38c Max 74c
CPU Core Min 1.32v Max 1.37v

Biostar TP67XE Mobo
Xigmatek Gaia HSF

I ran 4.7GHz and an error was detected and I'm not prepared to go over 1.4v.

Still beats my 1.2Ghz oc of my E4300 from 1.8Ghz to 3Ghz, so well chuffed with this bit of kit.
 
Voltage seems pretty high for 4.6 IMO, but it may depend what the biostar boards are like, as at the moment your running at 1.40v for 4.6ghz (1.35+0.05=1.40). Lower voltage = lower temps, BUT at the moment are looking ok. I certainly wouldn't want to push that any higher without a better HSF, I would say 4.6ghz is about your limit for that cooler.
 
Thank you.

What's worrying me is around a 45c idle temp. Is that anything to worry about when my max load temp is 74C?

I'm using some old Coolermaster High Performance thermal paste but do you think my temps indicate a bad seating?
 
I have speedstep enabled.

I have a Coolermaster 311+ case with a 120mm bottom front fan and 120mm top rear fan.
 
Guess if my temps on load stay below 75c on 1.4v, it's probably that I don't have enough airflow.
 
75c for 1.4v @ 4.6ghz on that HSF is probably about average tbh, a slightly roomier case may shave a few degrees off and maybe a voltage drop might reduce them a further few degrees but nothing drastic.

There is room on the Gaia for another fan if you haven't put one on already, that should give you a decent cooling boost.
 
Thank you.

I will look into getting another 120mm fan to put on the Gaia.

I tried 1.35v (no offset) with 4.6GHz and the PC just turned off running through OCCT.
 
You don't need to worry about your idle temps (admittedly they're warm but they're OK) and your load temps under maximum stress aren't that bad. 72 Degrees with your clock and voltage is pretty respectabble with that cooler and case - and normal usage: games and apps wont produce those types of temps. Also, your voltages are about average for 4.6GHz for a 2500K with an average cooler.

How did you apply the paste on your HS?

As your Heatsink has exposed heatpipes this method is usually advised as the gaps in the HS base will suck up a pea sized blob and somtimes hinder spread.

Additional: As already suggested a better case/ventilation will help but a better quality Cooler, such as the Silver Arrow (or similar), will give significant temperature difference - if it will fit in your case.

I spread a thin layer of thermal paste onto the CPU die.

After reading that article though, I will resit the heatsink again using two lines of paste across the heatsink and add a 120mm to pull the heat off the heatsink out of the case.

Thank you so much for your help Plec.

No worries.

Don't be too surprised or worried if your temps don't change with a resit as your application does accomodate the exposed heatpipes. The only reason there would be a radical change is if the gaps had sucked up too much of the gunk or there wasn’t full contact between the HS and CPU.

As mentioned previously your temps are warm but nothing to worry about and well with tolerance; especially when you consider your hardware and clock/voltages. In fact you could argue that your temps are quite respectable considering... (An intake fan would be advisible though as this may improve temps slightly and cool other core components.)


However, if you do decide you want to reduce your temps significantly a better cooler, such as the Silver Arrow, would make the biggest difference – ~10 degrees. However, your case specs won’t accommodate a large cooler so you would have to factor this into your budget too. This would seem expensive but you would be able to reuse a quality case for many future builds and the cooler for as long as it’s supported – which is usually long enough to get value for money...

I did further tests with a stable overclock I've had previously at 4Ghz and 1.2v and my idle temps are quite interesting. My 2nd core is at 26c but my 3rd core is at 37c. This must be an issue with the amount of pressure the heatsink is putting on the CPU.

I'll unscrew the heatsink and carefully screw down each side evenly and post back results.

I have mine running at 4.4ghz and im having to use 1.35.. I cant hit any higher at these volts.....
 
Could just be down to the chip, its purely pot luck when it comes to sandybridge it seems. On a user average I would say that voltage is higher than average...

Yes, it's mostly luck/chip although MB, cooling and BIOS tweaks all have their part.

Having said that you seem to have a gem of chip (as do i), looking at your sig, so your user comparison isn't atypical to that of most users. 4.8GHz at sub 1.32V is a cracking clock to voltage ratio - great chip.
 
Yes its been good for me, though 4.9 and beyond just isn't do-able under 1.4v for me, I've hit 'the wall' :(

I was ruling my self out of the 'average' as I know my chip is good, I was referencing to other posts and sigs around here that on a most part are sub 1.35v for 4.4-4.6
 
Nah, still getting the same temperatures so I'm thinking it's not having proper airflow as load temps are still below 75C.

I have dead heat where my DVD drive is, so I'm guessing if I stuck a 120mm blowing through my CPU, those temps would drop nicely.

On 1.2v one of my cores is at 26C, so I'm far more content with everything after having a bit of a fiddle.

I'm now testing 4.4Ghz at 1.35v and so far so good. That could well be the figures I stick with.

Come to think of it, I may just get rid of the 2 stock 120mm case fans and replace them with silent fans.

Thanks again Plec.
