i5 2500k overclocking help - Page 2

post #11 of 18
Thread Starter 
I'm almost 110% positive I updated the BIOS to the latest version a couple weeks ago but I'll double check. I'm gonna give this a shot now I'll be posting my results shortly.

It worked! Thank you! Right now I'm running Prime95 and I think my temps are a little on the high side. CPU is at 87c. Maybe bump the multiplier down a bit or is this just because it's running a full load. Also did a standard and high stress test with Intel Burn Test.

Edit:

Just to clarify the CPU temp is 87c when running stress tests under full load. When idle it's 30c.

You need to keep that temp under 70 degrees Celsius, if you're running daily-use. My I5 only gets to 61"C under full load @ 4.3Ghz (1.22v) with a True Spirit 120. Yours is just too hot.

As others have mentioned your cpu cooler isnt up to the task of cooling your cpu too well...try upgrading if you want to run a high overclock buddy. prolimatech megahalem, noctua d14, corsair h80 are all very capable.

Glad to hear that it worked with the settings I provided in the first page, however there is more work to be done before determining whether or not you can run that overclock 24/7 or not.

As other's have said, 87c is quite high and I personally wouldn't recommend running that for 24/7. I much prefer it to be lower than 85c whilst stress testing.

Try this:

Continue testing with custom prime blend with up to 90% of your RAM (goal is to run it for as long as you can, 12 hours should be enough), but this time start reducing the vcore from 1.35v. If the temps are still hitting above 85c then yeah it may be a good idea to reduce the multiplier or get better cooling to maintain the vcore and overclock. Let us know how you get on, preferably post screenshots of prime running with realtemp.


Good luck thumb.gif

Ok well I might be looking into water cooling as a summer project so I'd rather not waste $80-$90 on a nice heatsink if I could get a nice cpu block instead. Once I figure out what I'm doing I'll make the appropriate decision. For now I'd rather mess with the overclock to make it run less hot. Now my concern is that before when I did the auto overclocking crap and started playing minecraft, I would get warnings saying temps reached 86 or degrees. After I manually overclocked it that stopped occurring and now runs SO much cooler. It didn't go over 46c after the oc.

My next noobie question would be can lowering the vcore lower the temp? I would assume that the more electricity the more heat? Last thing is prime blend the same as prime95 lol

Yes. Less Vcore will make it cooler. Mine came stock with 1.19volts @ 3.3Ghz and in Intel Burn Test i had a max temp of 57"C . Now I'm running at 3.7Ghz with 1.07volts and i don't get over 51"C on the hottest core in IBT smile.gif . The idle temps remained the same because now i have the voltage on manual (so it's stays at 1.07 in idle and load) while before it was @ 0.99volts in idle and 1.19v in load. thumb.gif

That makes sense thanks. I will definitely start trying to lower it and mess around with it a bit.
