i7 860 @ 4.2 on air - volts?!

post #1 of 7
Thread Starter 
Hi all






does these volts seem ok ?

Its hard for me to test stability since prime95 is gettin too hot if i leave it on for too long. Alternatives if i dont care about stresstest-temps?

using a asus sabertooth 55i mobo

thx

If it gets too hot I would turn down the OC a little

If you dont care about stresstests (why wouldn't you?) temps I guess you can just leave core temp on in the system tray all day and use it for whatever you use it to and see, like having it running while gaming and see max temp after.

Indeed, if you are exceeding recommended temps on prime you need to turn it down or accept a degraded chip life.


If you're reaching thermal shutdown, you have more serious issues and it prob wont be worth running at that OC.


Options could be stability testing on cold air, improve air flow or get better cooling




Edit:
Argh noooooooo, software overclocking D:

Do it in the BIOS, also I believe the 860 can use higher multipliers than 21, I would recommend that too, it will take strain off the board.

Those volts are very good for the speed. I've had a few of these and none of them would do that clock with less than 1.35v. Keeping these cool, especially at that speed is a challenge.

I wasnt doing it via turboV - just to show the volts! and no i cant do more than x21 im afraid.

however today i got a new cooler, a used corsair H70. Using both fans

I have question tho. How should i connect the pump and the 2 fans?

right now im running the pump into my mem fan pins..

and the 2 fans on CPU and SYS 3-pins. however im only gettin 1500 rpm on the sys pin - 2000 rpm on the cpu

how can i make sure the pump is running full speed? and is there a way to get 2000 rpm on both fans? cant find anything in the bios

thanks for your input!

btw. temps are looking a lot better now... idle 43 - load up 75 IBT

I think the manual said pump on PWR_FAN and the push/pull fans on CPU header, I'm sure the push/pull fans should be in CPU header, dont know if you can place the pump in whichever you want tho but I run mine in PWR_FAN. Fan speed should be in BIOS under hardware monitor --> Fan speed control. Then check what header you put the pump on and set that to run @100% all the time.

1.272V is pretty good for 4.2GHz, but are you sure it's stable? Using turbo enabled, you can set 24x as default, and lower the BCLK. I can't run mine very well at 200 because of voltage issues, but for 4GHz 24/7, I basically need the voltage you run for 4.2

My idle on an A70 is only ~32°, so I must ask what your ambients are? If you're unstable, you will need a voltage boost.
