Interesting that you decided to kill your CPU. Let's hope you succeed!

Ever heard the phrase: "Curiousity killed the cat"? tongue.gif But nah, I get your curiousity.

I'm struggling to get stable at 130 x 37 :/ Max temps of 78 avg, usually around 70 when folding, but it's getting a LOT of juice. More than I was initially comfortable with, but I guess I've made peace with my CPU not living forever tongue.gif

Been pondering if I should see if I could get it stable below 1.5V vcore at 130 x 38, but meh, not sure.

...Yes i know that saying well ! I got spare 3820s ones a ES and the other is a Costa rica just in case:p . Anyways my chip wants more juice so 1.6v is the limit so i had another go....2530947.pngbiggrin.gif.......try 1.45v vcore and llc on ultra or extreme works 4 me:thumb:
post #1385 of 6499
I have my vcore at 1.37 in the bios but when i run prime it drops down to 1.34-1.35 why is that?

That is called Vdroop. It's a built in feature by Intel which is to make sure the voltage doesn't go beyond what you set in BIOS. There is always an overshoot when there is a voltage change & this feature prevent this from happening. Depend on the quality of the hardware, Vdroop can cause instability when overclocking. Otherwise it's a good feature. If your computer still running stable or not crash, you don't have to worry about it. If it cause instability, increase CPU Load Line Calibration to medium or high. Exceeding high is not recommended unless you have very good cooling system.

thanks and my cpu is clocked at 4.8 but my volts are at 1.472 under load and that is where it is stable. do you guys know if that is to high of a voltage for a 24/7 setup and how do i put up a screen shot so you guys can see what im looking at.
P.S my temps under load at that voltage is 66-67 and idel at about 26-30

Well, I finally got some time to overclock my 3820. If everything goes well, I'll pass a 24hr Prime 95 session at 4.56ghz. Midnight CST is my deadline. I'll post up with screen shots soon as it passess. I apprecaite all the good info and Reads/Writeups! one this passes. I'll probably see if i can lower the Vcore down. Right now it's on Auto except 1 setting because of XMP. Wish me Luck!
post #1389 of 6499
Well, I'm a little late, gave the rig a 1 hour cool down session for idle temps etc. I don't think it's too bad for a first time. I'm sure there are capable inprovements. Rig is In Sig. Anyone know if the SB/SB-E Club still active? would like to be added to the chart most def.

24 Hours Prime95. 1 Hour Idling. H100 was set to "Normal"
1.25 Strap, BClk Down clocked to 120.00 to get Mem to 1600Even, Bumped Memory to 1.575V for giggles, Rest Shows On CPU-Z Etc.


P.S. for some reason, after cooldown, i rebooted comp to save profiles, started windows, and went to shut it down, hung up a bit, then when i turned pc back on, it POST said OC Failed! mad.gif Went in, double checked everything, everything was fine. reloaded the profile for the hell of it. rebooted. works perfect again. fluke? or i guess there's a tweak i still need? figured 24 hours was enough... oh well. I'll start gaming and see what she does.

how do you have your volts so low at 4.56 im at 4.8 and my volts have to be at 1.48 to be stable?
