question about 2500k voltages

post #1 of 10
Thread Starter 
sorry if this is a newbie question but i cant find a "newbie help" forum. on coretemp, it reports my VID as 1.360 during my first load test at 3.8ghz but HWInfo and HWOpenmonitor report my Vcore as 1.260. Does anyone know what the VID is and why it is any different than the Vcore?

thanks!

running i5 2500k @ 3.8 ghz (first time overclocking) on a gigabyte z68ap-d3 with 8 gb ddr3 1333mhz ram patriot 2 gamer series

Maybe Vdrop.

( drop in voltage )

Thanks! I'll try to investigate that later today . Any other suggestions?

Hmm, not really sure. But Vdrop is quiet normal.

If you have a stable clock, then its nothing to worry about smile.gif

okay. my last question is why do we have to do stress tests if were not doing serious overclocking? whats the utility? if i want to go up to 4.2 or 4.3 ghz on my 2500k, knowing that most people dont have a problem, whats the point? if it passes the stress test but then gets BSOD in games and while actually running programs (which ive heard of), do stress tests have any meaning when not doing serious overclocking work?

also, how do you know if you "fail" a stress test? i know what that means for the IBT tests, but prim95? what am i looking for? if the computer turns off and stops booting, is that what you mean by "fail" because at that point youre already screwed.

thanks again!!

A stress test is a good idea, because programs like Prime95 will push your CPU to the max. It should be used in conjunction with actual programs.

I don't know what system you have, but if you are planning on overclocking above 4.0, deffinitely invest in an aftermarket heat sink. Something like the Hyper 212+ would work great. I use it, and my temps are very good, below 75C on load and in the 30s at idle.

You know if you fail because your computer will reset/crash/BSOD.

Here is a great guide that I followed to achieve my 4.7GHz overclock.

You should put your components into your sig rig so that people will be able to help you better. Have fun.thumb.gif

im not the best at explaining things but for me stress tests are important to make sure your system is stable and wont crap out when your are doing extensive stuff. you can also say it is a test to make sure you have a decently working processor.

people have different views on how you fail a stress test. personally, if i go 24 hours without fail (bsod, screen freeze), i am confident to say that i am stable. and so far 24 hr tests havent let me down.

thanks for everyones help so far! i repped all of you.

a couple of other questions. ive read that having the bus speed/BCLK anything over 100 mhz is unnecessary and potentially dangerous for the mobo. i used the cpu ration setting to increase my clock to 4.0 ghz in my stress test right now. my vcore is 1.26 which is pretty good, but my bus speed is rated at 100.3 mhz (becuase the mobo setting is on AUTO and not locked at 100). is this dangerous? should I lock it to 100 mhz? whats the danger in it being upped to 100.3 mhz?

thanks!

Regarding your stability question, it's a good one. The basic point, as I understand is this: When a the CPU screws up because it's unstable, it can (or maybe does) do something that makes it degrade faster. The slightly longer version is that an error occurs when certain parts of the CPU aren't turned on/off at the right time, which puts those parts in situations they weren't meant to be in. I think I read about it in the Sandy Stable Club thread somewhere, but that may not be the case. It's been a while, so I'm terribly fuzzy on the details. It's questionable how risky it is to your CPU life; most people just want to maximize it and not deal with crashes/errors.
