View Full Version : How much is too much?

I just got a 1800+ T-bred and seeing that I'm used to Palimino's the low voltage I'm seeing with the T-bred throws me off.

I'd really like to break 2g with this chip and I think it's possible. I was first booting at 2g and geting BSOD's. I uped the voltage a little and it was stable for a minute. With more voltage the chip stayed stable longer.

But I'm gettin scared :eek:

I'm at 1.75v right now and I wondering how much more juice to give it. I've seen people throwing 2v at them but I can't think that that is good for them.

Mdzcpa had advised to go +.25v on straight water for daily use. If that's the case and my chip defaults to 1.5v then I'm there now. Temps are lower than my 2000+ @ 1.8 1.85v right now and I think this chip has more in it.

Advice? :)

Remember...I gave you "rule of thumb". If your cooling is above average you may certainly get away with more. In the end, though, you will find that you hit a point of diminishing returns with voltage increases regardless of cooling. That's the point to stop. In my personal opinion, it isn't worth throwing the last .05v (or more) at the chip only to gain the last 50mhz....except, of course, for benching and tinkering around.

The key is finding the sweet spot for day to day use.

But...that's just my own approach:)

EDIT: BTW, anything under 2v should be fine for short term testing purposes with water cooling. Let your temps under load dictate where to stop on the voltage bumps along with the "diminishing returns" consideration. I think you'll find that anything over 1.9v will be darn hot though....so be very careful.

I would prolly say 1.85-1.9 would be where I draw the line on straight water.

in the good old days (i really need to upgrade...) you'd find like mike says you'd reach a point where the increase in voltage allows only a small increase in clockage and a massive increase in heat. on the old chips it used to be between 2 and 2.1volts where i'd run in to trouble with water cooling and at around 1.9 and 2 volts on good air cooling.

i'm afraid i'm not up to date on the new chips but if you follow the rule of trying to keep temps below 50c then you'll never run into trouble with the kind of voltages we're talking about heat is a much bigger problem than voltage
