Two Quad meet : Abit Quad-GT+ Kentsfield first test

[over@locker886]

Abit AB9 Quad-GT
Intel Core2 Q6400ES (2*4MB L2)
4*512MB XtwinZ DDR2-9100ES
Inno3D 7900GT
Aerocool Aeropower 550W

Once I can boot 6*450Mhz and windows running, but I want run Spi 1M system freezed, and never able to hit 450Mhz again

So..,Max FSB@430Mhz




orthos running 3,2Ghz, and PWM underhot ,system shutdown when pwm4 over 162C



and some everest test on 3,2Ghz..
everest photo
cpu zlib
fpu julia
fpu mandel
fpu sinjulia
memory read
memory write
memory copy
memory latency


Coming soon... test with Q6600

[jugeen]

grat m8! keep on OCing!

over@locker,

have you checked your pwm heatsink? load should spread more even across all 5 pwm's and so should temps. the very odd temperatures across the 5 pwm's lead me to believe the heatsink is not seated properly!

for the current your pwm's are delivering, i would expect temps somewhere near 90C or may be 100C!

i once run 1.6V vcore trough my e6400 which lead to a pwm current somewhere around 100A and pwm temps were nowhere near yours!

also, even if you are going to use stock heatpipe configuration, you need some airflow through the pwm heatsink. if your cpu cooler does not supply this additional airflow, you have to place a fan at or near the pwm!

i had my quad gt under load the other day too, seems 2 of the pwm's do get strained especially over 4ghz, it tripped out with load, I may try checking for mosfet contact, I have a feeling the circuit just does not handle the current draw of quad well, hopefully I'm wrong......

throw an 80 or 90mm fan over the PWM area before you kill the board.

make no mistake about it,, that PWM is running that hot,,

Actually, you're right.

I bought this mobo as second-hand. Saler told re-paste the pwms, but At weekend I removed again, and grease pwms. And I put 3 zalman heatsinks about big IC in front of 5 pwms.
I sold Q6400ES, wait Q6600 and will check temps again.

I would like to see some thermal shots of this board, like this:


What are you guys using to cool these boards. I see one member liked the HR-05? I'm not sure what to get with it.

Hehe be carefull, that's how my Abit IN9 32-MAX died

[situman]

1.6vcore, 3.9ghz Xeon 3060 PWM without fan is 110C. With a fan is still near 90c. O i was stupid enough to touch it and got a nice little surprise and a "marked" reminder not to do that again.

nice OC

160C on PWM is sick

[Ajfina]

U have to remove the heatsink takeoff all the crap sticked on bottom of heatsink and apply a good thermal paste to the PWM and u will see a big drop on temp , i did that and my PWM rarely go higher than 50 even at 500FSB or more
like these pic at 515 and look at PWM

[rithina]

the pwm is more than 140 and still increasing when i do 400 x 8 on my 3210 ES priming and eventually shut down due to heat...btw, i replaced my default HS with those ram sink...cant push high on quad due to heat.. have to sell it off..for conroe.. it is still ook

Good, but you try orthos..and for quad core need more power and pwms hotter than only conroe run with orthos.

Thx

yeah..
