I used "Gelid GC Extreme" and although I haven't done extensive testing with other Thermal paste, I am assuming its working quite well.

I am using a Cooler Master Hyper 212+ EVO and live in quite a humid city [year round] and basically I am idle at about 35 - 38 OC'ed at 4..4 GHz. Some may say that's a bit hot but as I mentioned I live in Bangkok, and my place gets rather warm.

When I crank up the AC, and cool down the place, I can get lower temps.

The results were very very impressive for all processors [hence the reason I have & will always be an Intel CPU fanboy]

His final thoughts were, if you already own a i5-2500k there is no need to upgrade to a i5-3570k, but if in the market for a new processor, he very much recommended the i5-3570k.

These are one-hulluva- Processor.

I'll stick with my i5-2500k for now.

I have a question for you guys.

Can running a stress test for stability like Prime95 and IntelBurn actually damage any hardware, as it is know to put serious stress on components??

Reason I ask is that I did an OC at 4.4 GHz - 1.31v and ran Prime95 a while ago just after I built my new rig. Everything seemed stable after running Prime95 for several hours.

A couple of days later I started to BSOD. After a while of trying to figure out what was causing this, I found the problem to be the Hard Drive.

So in this instance & I know this sounds very unlikey but could my HD have been damaged in the process of stress testing??

Initially when it happened I straight away thought that it must have been related to the Stress test by Prime95, as I started BSOD just a day or so later. Was it coincidence????

Your thoughts??

Cheers

Even Haswell won't really destroy the 2600k, maybe 25% increases in performance. I will stick with what I have until (I think it is called...)Skylake?

Basically the tock's or 'new micro-architecture', for 14nm/10nm models.

I really don't see a reason otherwise. Upgrading GPUs and HDD/SSDs have a better bang/buck. My only 'bottleneck'd' problems on my computer come with gaming and video editing where my GPU is throttled to 100%, and my storage where I am limited by how fast I can read/write.

I forsee myself dropping $3K on a new rig in 2016-17.

The 2500k/2600k's are just SO DANG AWESOME!

Intel/Nvidia fanboy for life!

I tried today playing around with my i7-2600K, that was my first attempt to approach its limits.Here is the result:



Not so lucky though as I couldn't get into windows on 4.8Ghz.Temps are not that good but satisfactory enough considering they are coming from a humble Corsair Hydro H50 and in a quite high ambient temp (25C+).I 'd really want to try on 4.8GHz but lack the knowledge for that level.smile.gif

Did you enable PLL Overvoltage? Could be why you won't get into Windows at 4.8GHz.

As long as temps are in check stress testing should not actually damage anything, getting way too hot can degrade things faster but should not kill it unless it was faulty already.
Probably just coincidence, or the stress test just exposed a weakness that was already there.

Actually these were my settings from the start:

By All cores= 45, 46, 47, 48
Internal PLL Overvoltage= Enabled

Load Line Calibration= Ultra High
Phase Control= Extreme
Duty Control= Extreme

Cpu Offset Voltage= 0.05 (multipliers: 45, 46), 0.020 (47), 0.030 (48)
CPU Spectrum DIsabled

EIST, C1, C3, C6 all Enabled
Vcore= Auto

*when failed to boot at windows (@4.8) I also set:
VRM Frequency= Manual
VRM Fixed Mode= 350

It posted just fine, displayed the windows 7 boot animation, then a black screen, silence and then a BSOD.smile.gif

I maybe should have watched HW monitor more carefully and find a fix vcore value so that I may would have saved some millivolts (hence temps) but as I said my knowledge on OC is quite limited. coolsmiley02.gif

Cheers FtW,

The Prime95 test ran ok, off memory [it was almost a year ago] everything seemed stable and I do recall monitoring it all. It was my first OC ever, so when the computer started to BSOD a couple of days later, one would initially think it had to be the stress test that did the damage.

As I mention, later it was found to be a faulty HD.

I am about to re-OC the system again, and would like to run at least a couple of tests Prime95 and AIDA64, to check for stability and wanted confirmation [or call it opinions] about the above.

Cheers

Just like FtW 420 said, if your temp while stressing is not too hot or daily usage is not too hot then it may not be harm smile.gif but remember better don't use Vcore +1.40 volt for daily like 1.45v eventhough some people with best WC still do it and chip is fine with lower temp.

Agreed smile.gif It's time to Enabled PLL Overvoltage at that case.

Are you trying to get 4.8GHz with these setting? Quite new to me smile.gif I usually use Adjust CPU ratio to 48 or use Turbo Clock OC by set all core to 48.
Don't use Auto Vcore at 4.8GHz it will be too much, I guess max Auto Vcore better use at 4.5GHz.
