ya thats my next goal 5.0 :D
stock for them is 1.8~1.9 voltsQuote:

i run mine at 2.2 is that maybe why i cant get over 1066 stable? (445fsb)Quote:

This is for now. Problem was with my memory, maybe too aggressive setup with too low memory voltage. I'll deal with memory later. Passed 12 hours of Blend and Small FTT-s.

Mine needs 1.376V under load to run stable at 4,0 GHz. Maximum temperatures under load while stress testing are 64 C. Is this OK for 24/7, or I should run it at lower voltage?
to hot ? thats a hard question the limit eye believe is 72c
but 50c to hot for me
1.376 and 64c does not sound at all bad for benching or stress testing. While those numbers would be a bit much 24/7 keep in mind that you will rarely attain those temps during normal usage and then not for long. The consensus on vCore seems to be to not exceed 1.4v.
So, I'm fine with 4,0 GHz. Anyway I have strange proccessor batch. For 3,6 GHz it needs 1.232V under load, for 3,8 GHz it needs 1,304V under load, and for 4,0 GHz needs 1,376V under load... it has big gaps for little change in speeds...Quote:

My 8400 is exactly like yours.Quote:

As soon as I boot for the first time, the time it takes me to enter the bios the Temperature already shows 38º
waterblock contact is perfect, so...... why so hot lol
Are you using RealTemp? Because CoreTemp and Everest show wrong temperatures... they have wrong TJ Max...Quote:

i still think there are temp sensors that are off from intel myself
yes, 71c with realtemp (tj 95) with orthos small ftt.Quote:

Its just weird that some aircooling are doing 4ghz with a lot less heat....
Well, I guess Nirvana is pretty good air cooling and this temperatures I have are in pretty warm room, around 30 C....Quote:

you got a temp probe ??
If you're using water at 4.0 GHz and RealTemp shows 71C then you likely have cores making horrible contact with your IHS.Quote:

well I guess I will only know that after I try a different cpu this weekend :yepp:Quote:

Today I added a second radiator to the loop to deal with my watercooled 4870 because I dont trust my first one to handle a 71c e8400 and a 4870 at the same time...
The pump (eheim 600L 12v) is feeling very restricted though.... With all installed, she can only pump water about 3cm into the air :ROTF:
Wasn't there a theory about slow water? the more it stays in one place, more heat it absorbs.
Oh well.... its the price to pay for a 0db PC
no fans on the rad?
0db is a figure of speach :D
yes 2 fans, SILENX iXtrema 46cfm 11db working at 7volts. powersupply is the noisiest thing right now.
My E8400 @ 4.2 requires 1.5V, it's an OEM chip. :(

WTF?...34 degres idle and max 42 with ZALMAN 9700CNPS at 1.5VCore :shocked:....i can't belive that...that are temp for watercooling...and a good WC...Quote:

The more heat it absorbs and the less heat it dumps out to your radiator. Your 71C core temperature makes a little more sense now. :yepp:Quote:
