Oh yeah I did haha. I'm using a 110CFM brandless fan from robyn. Shouldn't be that much diff over the stock 90CFM sunbeam fan though..

got le... stock 1 max rpm only 1.9k+.... think am gonna change that fan too .. lol..
what's ur temp when idle? and full load?

Load is about 60-65C whereas idle about 45-50C. This is without EIST or Speedstep enabled.
90CFM to 110CFM yah i know, 20% diff, but not sure how much more effective it is lor =p

anyone using fm123 fan?
planning to change xigmatek s1283 stock fan with this. hopefully can get cooler.

anyway,
my test tonite,

3.5GHz (467x7.5 @1.325v)
passed 4 out of 5 ibt tests.



not give up,
3.6GHz (480x7.5 @1.375v)
passed all 6 tests



get excited, try increasing
3.67GHz (490x7.5 @1.4v)
passed 5 out of 6 tests...



finally increase fsb to 495, can login to windows! 3.7GHz, baby!
but a few seconds ibt start, hang!
must clear cmos for that...

but happy enough knowing that my system can stand up to 490fsb.
need better cooling system inside the case to get the temp down a bit.
core temp read 80+ degrees.

now will try to get 3.5GHz rock solid stable.

iirc using higher cfm fan only will give u few degree c of improvement...something 1-3c maybe....

cmiiw, fm123 max cfm is 100+. xigmatek stock is 56.3 from official site.
CM performance fan is 90 cfm.
anybody has recommendation which fan to use to replace my hsf stock fan?
looking for fan that has +- 100 cfm or more.

thanks!

im using 3xfm123 on my radiator... its the best noise to performance ratio fan so far.. u can turn it to the max to get 100+cfm but its noisy ...

for a xigmantek the high cfm fan doesnt play big role so much,but if you on core contact freezer it show quite a good diferent..

@kaiser falco ^
is it?
then will need good active cooling in my casing.

im really puzzled how u guys manage to oc high with low vcores..
must be coz of mobo? i need high vcore to oc 3++ cud be my mobo sux ><

i notice 1 thing for the penryn quad core aka yorkfield,

the more vtt(vfsb) the less vcore needed for a particular clockspeed, hence running cooler.

may i know wat vtt(vfsb) most users here using ? i using 1.3v

but dun increase untill 1.4v or above as it will kill ur yorkfield according to anandtech

actually 1.4v is advisable MAX vCore, not vtt

Your mobo's an X48-DQ6 though. Can't be that's the bottleneck. Maybe I was just lucky la..seems like my proc's exceptional for some reason.
I certainly never expected a 12hr prime stable proc at 3.5Ghz 1.24v..

I'm running 1.175vtt.. I will try higher vtt hb see if vcore can be lowered.. Btw it's vtt that kills ur proc not vcore..

actually..it applies to both, VTT and Vcore

Yupz I agree 100% there. Both vtt and vcore..

suicide run, 470FSB on P35-DS3P. any higher, wont boot.

vCore 1.40v
vFSB +0.35v
vMCH +0.3v

temperature:

Lol priceless? Very hot issit? Crazy that you need so much vcore to get to 470 wei, probably you can tweak Vtt or GTL refs..

yes, 54-58C IDLE...

nope, my P35 dont any GTL refs. if i drop any setting of Vtt (VFSB), vMCH or vCore, it wont boot. but that just a test run. dont bother with those insane speed haha

i tested Everest benchmark on FPU, 3.5+Ghz X3320 at least twice faster than a stock quad QX6700. insane...

does this apply to vdroop also?
coz i notice when LOAD vcore drops like 0.04 ><
and whats the connection between vtt, vFSB and vMCH
coz gigabyte's bios no vtt le

Added on September 1, 2008, 2:05 amhav u tried CTRL+F1 when entering bios?
coz that'll unlock cpu GTLREF on my bios but i dunno what to do with it lol
