90nm Vcore Max??

[asicman]

For those with 90nm chips, what Vcore do you run everyday... I'm finding that I can't get much out of my 3700+ SD without raising my Vcore to 1.62 or so... And at 1.62 in the BIOS, cpu-z reads about 1.65 or so.

most people dont feel comfortable raising it above 1.55. normally thats all that is needed. if you give you full specs and details on your overclock we may be able to help you.

Well, it is an EPoX 9NPA+Ultra mobo with 3700+ SD and XP-90 with L1A, 2x1GB PDP 2-3-2-5, 550W Aerocool PSU. I've measured the 12V rail on a scope and it is solid. I've tried Corsair 512MB VS RAM, to make sure mine wasn't the problem, and it isn't.

No matter what I do, what CPU dividers I use, how far I divide down the memory and the HT, I have been stuck at 2540 with BIOS setting +0.075 on Vcore. That setting gives me a 1.55V reading on the BIOS startup screen, and about 1.56 from cpu-z.

Tonight I got to 2700 stable with SuperPi at +0.125 Vcore which gave me a 1.68V reading on Vcore at the BIOS start screen about up to about 1.7V from cpu-z.

I am really starting to wonder if the EPoX BIOS readings are way off. But, I guess it's not really worth it to assume so.

1.53ish

If you use RMclock to downclock your cpu when it's not in use you can set a lower voltage for idle/mid load, while having 1.6v or so at max power.

mine is at 1.55
doing good,
though I have water cooling,
so, it helps keep my temps barely 40 C on load

1.55V 24/7 for the last month and a half or so. 2.8Ghz (255X11)

 

[t3h l337 n3wb]

~1.495

You shouldn't go above 1.6 on air.

 

[RichUK]

i use 1.6 all of the time 24/7, the temps at load are 53c, but if i was to push any higher the voltage will kill the proc not the heat..

 

[imported_Kensai]

<1.6V

 

[Leper Messiah]

Shens you guys. I've been running 1.6vcore on stock cooling since april, and I haven't fried anything yet.

 

[Diogenes2]

I Ran 1.7 for several months on my 3500+....

No problems.. ( plus I'm very comfortable ... )

Not running it now because have new 4200+ to play with...

 

[n7]

Mine's at ~ 1.55V.

 

[mindwreck]

my semprons at 1.68v right now. pushed overclock to 2.6 and still testing
