Undervolting a X9000 on a p6860

I know a few people here have done this. I was just wondering how low you could go and what kind of heat you were running at with everything maxed out.

Also if anyone has gone through the trouble and figured about he best configuration if you could let me know I would really appreciate it.

Thanks

 

I have mine uv'ed to 1.0volts in all but the top two multipliers, which are stable at 1.1volts.

Each chip will be a bit different though so you'll just need to see what your can do when you get it.

The max temps i get now are about 63-66

 

@Kamin, I'm very interested in undervolting, but the guide here says I have to test for 45 minutes per multiplier change per volt step change (like every 0.5 or so volt I go down).

...I mean, is that neccessary? That could take up tons of tons of time I don't have. My T9400 runs @ 1.250V at the moment for maximum power, but I'd like to get that down to a stable point as well as every other multipler in RMclock without spending over 12 hours...

 

Actually the guide suggests a 10 nimute othros run every time you change the voltage.

The only long test you run is the 3 hour test at the end to make sure it works perfectly

Yes its a time consuming process. But if you follow flipfires guide you will have no problems. If you start cutting corners... well you might do perfectly fine of you might get a hard core multiple unstable multiplier BSOD that takes you longer to fix than to just do it correctly the first time.

Just take one random saturday that you have free and were going to bum around on the internet for a few hours and start the process. You dont have to finish it in one sitting. Just do your top 2 multipliers and the quite until you get more time and work your way down.

 

you don't have to do them all.
as you dont have to use all multipliers,
from x10 and below i cant go under 1.0v (cpu restrictions?) so actually had to test only 5 mutipliers. and since i see no temp gain in using x6 over x10 when both are 1.0v (both idles@40c) i don't go down to x6 when plugged in (power on demand).

hope this is of some use.

 

Does anyone know the max temps for a t9300 just running stock? I am just trying to contrast the difference in heat between the chips. I know the t9300 runs cooler but it is dramatically cooler or just notably?

 

Its dramatically cooler.

The t9300 runs cold as ice once undervolted. I think Diablo was getting my idle temps as his max temps (i have the x9000 and he has the t9300)

 

Hey Kamin_Majere what clock speed are you running your x9000 at 2.8ghz?

 

3.0gHz, but i would gladly run it higher if the Gateway BIOS didnt suck

 

wow, i smelled my name from the other forum. lol.

i cant give you temps off of the cooler as i rarely ever run the computer without the cooler, but i can tell you that i dropped about 14C off my max temp under load after undervolting.

my temps now are low to mid 20's idle max 50C (only one time has it gotten that high) under load.

 

yes, but a t9300 IS the lowest heat producing chip to date. when i had mine.. i got it to 18c

glad to see the under volting is still going strong!!

 

Hmm, what about the P9500? Higher clock and 10w lower...

 

don't know for sure about the p9500. haven't heard anyone going lower than the t9300's and the p series has been out for a few months now.

 

I'm not the expert on CPUs but I thought the P series had a TDP of 25W and the T series had a TDP of 35W, therefore producing lower heat and staying cooler. How a T9300 stays cooler than a P9500, going against physics, is beyond me, lol.

 

hey, join the club! but it's still the lowest chip on the market. unless one has hit 18c and we didn't know about it...lol
test have been ran....

 

Oh you are basing what you are saying according to what you saw it hit? Lol, I wake up in the morning on my T9400 and get that, it's fall around here.

 

no. im basing it off of me running my system, then let it sit idle for 5 minutes and get my temp reading. in a room that is above 80c on average. right after running orthos for 10 to 20 minutes. after running wprime for 10 to 20 minutes. 3dmark for 10 minutes. vantage mark for 10 minutes. cod 4 for 10 minutes. crysis for 10 minutes.

 

So after running all that for all those minutes, what is the temperature?

THAT is the difference between the T and P CPUs, the T will have a higher average/max than the P.

 

hpdv9740us about 80 degrees
gateway 6831/6860 about 60
on top of a bed...lets just say it was up there. lol
gateway 6831/6860 22/24. i would have to wait about another 5 minutes for it to drop to 20 and below

these we're the systems i tested it in.

 

So what do these tempatures mean in terms of real world use. If I have a CPU that is maxing out at 66C and a GPU at 60C is this thing going to be catching my lap on fire?

Will the fans be so loud I cant hear anything?

Whats the user experience like, in your opinion, with hot components in a p6860fx?

Thanks

 

nope. i would start to worry if it is around 90c's on either one or the thm0 sensor. other wise...people tend to go over board with the temp stuff.

 

Just for the record I got my x9000 and was able to get the top two down to 1.1 volts and all the rest to 1.08 volts.

I idle at about 25C and max out at 55C

I'm not overclocking
