955 BE @ 4.0ghz

[arnogriffith]

I overclocked my 955 BE @ 4.0ghz using default voltage of 1.40v. Is this ok?

I can run benches and it is working fine, it's just that the temps are not accurate when I use CoreTemp and AMD Overdrive. Sometimes its not even detecting or showing the temp at all.

It is stable @ 3.7ghz but i am wondring why default voltage falls on 1.40-1.44v.

The temps im getting are a bit off. On idle, it is about 40C and 54C on full load. I have C3 and it seems stable @ 4.0ghz using prime95 for 30mins.

I have it on 3.7Ghz with 4 hours of prime95 and luckily it never crashed or BSOD with temps of 54C.

Im trying to push my luck Ocing it to 4.0 but im quite scared because the temps are the same with 3.7 and 4.0 @ 54C. The max temp I got is 54C on all the tweaking i made.

before i start pushing it again, I would like to know if 4.0ghz @ default of 1.40-1.48v is enough and wont cause any damage to my rig.

I have Oced the RAM to 1600mhz with 9-9-9-24-1T.
HT is at 2000 and NB is 2600 with voltage of 1.256v

Here's my Rig

MSI 890gxm-g65 mobo
Kingston 2x2GB DDR3 1333mhz
PII 955 BE

I am planning to replace the stock cooler with hypher212+ soon because summer is near.

Is it ok for my rig to push it further or stay @ 3.7ghz?


Thanks.

I got a 965 stable @1.45v 4.0 GHz..Voltages look OK to me....1.55v is the limit but I wouldn't risk getting near that I use 1.5 volts as my limit...

just got the coolermaster v8 and its almost perfect! got my temps down for like 5-7C

I can OC at 4.0Ghz at 1.44v without worrying about the temps.

It's stable at 3.9Ghz, I'm going to check at 4.0

yeah you will be fine I got mine clocked @ 4.025 @1.424v been runnin that for over 6 months now on stock cooler with no problems at all with the 1.44 you will be fine @ 4ghz but dont for get to raise your ht linkage as well cuz that can bottle neck your cpu

i had to use 1.4875 volts for a true stable 4.0ghz clock on my 955.

why too high vcore 1.48 hmmm , how about temp when fulload test stress..?
i thin'k right 1.42 -1.45 get 4ghz at 955BE. check again your voltage CPU NB maybe too high. !
if you want 4.Ghz get cooler more bigger than hyper 212 like Noctua NH D-14 or Sprire Thermax Eclipse II (just my opinion)

i see spec you rig in above : Kingston 2x2GB DDR3 1333mhz
and in list : 2x2GB + 2x1GB GEIL Black Dragon/DDR3/1333/8-9-9-24 @ 1.6V
what is the true..?

 

[viper_69]

1.42 is what I got my 955be @ 4g stable with no problems with any stress tests or anything idles @ 27-29 under load with stress tests I max out to 60

for stabillity Oc must use RAM same Spec and JEDEC
