Sudden increase of CPU voltage during undervolting

ok loard the lowest eye could boot in was 1.025
opened aegis panel and cpu v reading 0.094
droped 1 tic and panel reading was 0.093
droped 1 tic and panel reading wes 0,091
droped 1 more tic and blue screened

so my E5200 wont boot that low to start with sorry
maybe cause eye allready beat it up a bit:D last night was trying to see top
max clock with it and fed 1.7 v into it but it still does 4.0 at 1.36 and that was what it did the first time it got fired up :D it's vis was 1.250 anyways

maybe someone else can try this for you
good luck

Thanks chopper. :) I would like to repeat in case of misunderstandings:
You dropped down CPU voltage to 0,912V in AegisPanel and reading was 0,91V (0,81 idle), too. And there was no sudden voltage increase to read on the right site of AegisPanel.
Is that right?

sorry no help, but just for reference...

my e8200 on a P5Q (p45) is able to run 6x333 on only 0.85v (prime stable) :cool:
(but i think they are supposed to be able to do that :shrug: )

@ThugsRook:
What will happen if you try 6x200?

right every drop resulted in a drop in v on panel ( also using panel oc function to do all this )
and not once did it overvolt
thier was an overvolt event once but it was the aegis panel before the last realse but dont remember what all the facts were
come to think of it believe it in this thread if not in another

EDIT: yes it was post #9 & post #10 explained it and yes if cpu multi keept at 1.00 default it wouldnt overvolt
but when using any multi other than default it would overvolt then only .. for me anyways
eye just quit using the panel for overclocking and used bios or set fsb

That is strange. I thought that the FSB of the E5200 can be clocked down a lot - because of 45nm. :confused:

If you got 0,91V adjusted then there is a mistake on my Mars only. Did you check it with CPUz, too?

6x200 ran fine, then tried 266 and 333, both passed. 400 failed and 366 failed. 350 might pass, havent tried it.

temps were extremely low, barely moved above idle when loaded :cool:

@ThugsRook:
Was the multipler 6 fixed @0,81V or would it go up on stress?

C1E and speedstep was disabled, fixed on 6x multi.

i was testing for lowest clock, then how far i could go on the boards minimum voltage... with a 6x multi.

:)

Yes, thanks for that ThugsRook. It is nice to know that the E8200 can go down to 0,816V. :) So many users could test it on Mars, too.

But I think it is not possible to enable EIST/C1E on PQ5/P45 anyway if FSB and VCore is adjusted, is it?

youre welcome :)

C1E works, it just lowers the multi to 6x at idle if its set above 6x. i dont know about EIST, never bothered to try it.

:)

DO'OH didnt lower fsb lol
will try again later for ya must of been the med's :rofl:
