Found out that priming FFTs at 8k uses more power hence higher CPU temps

Currently priming small FFTs without aircond, 8k can go up to 55c max, next 1 at 10k, dropped to 51c load. Improvement indeed a lot biggrin.gif
Air cooling around 58-62c

yup bro, u'll notice when it's small fft (8-512k), cpu temp is higher than large fft (above 512k). smile.gif

if want to test the temp..try IBT i guess..
so long havnt use IBT.... maybe i have to try it...with my stock cooler laugh.gif laugh.gif

ibt? meh... we aint runni on intel chip bro... i did a comparison last time, ibt is slightly cooler than p95... so p95 still d ultimate stability test for amd chips. but that's just me, others mite have their own preference. nod.gif

yeah true not intel chip..but this software also can find error for amd chip..just not that precise..

on my past exp (when i use alot of IBT since lazy to wait) sometimes IBT able to detect the prob way faster compared to P95..
but also sometimes, it unable to detect any bur p95 can..

about the temp.. im think it will make chip hotter than p95 esp when set to use more mem..nvm..will run an exp later to see..

ibt doesn't stress chip all d time (hence lead to cpu usage is not @ 100% all d time) while p95 is 100% all d way until one/more workers fail. smile.gif

im agree with u about the stressing part.. and overall p95 is the best.. since IBT have some uncertainties (sometimes can detect error sometimes cant)
that is y now i also using prime..but about the temp.. 275secs of IBT beats 17mins of small prime (im checking the max temp only).. even after every calculation of IBT, the temp goes down (means not 100% stress) still it can beats 1c for a short period of time..
on my system la.. donno other system..

alah..biar la..ini small matter..just suggesting the shinjite to check the max temp..not to check the stability on the 1st place.. icon_rolleyes.gif icon_rolleyes.gif jgn mara unker laugh.gif laugh.gif

Now I think back, no need to prime so long ler
1 day me not gonna use the CPU for like more than 3 hours? laugh.gif

So far no problems

Maybe I will try 4-4-4-10 for the lulz tonight

Hahaha, nowadays i only prime for 1 hour, usually if it pass then should be no prob at all.. laugh.gif
I used to prime for hours & hours dulu2, but as get i older i get lazier hence the shorter time laugh.gif tongue.gif

kita berbeda

last time i only orthos for 5min.. kekeke..but not for perfect stability.. just to make it fast to reach the wall.. after reach wall with 5mins, so will reduce freq to make it prime stable..

now only prime for long hours..

lol..if me..i will try IBT first..

If IBT fail dont hope for Prime to success..

IBT good is becos fast - - i lazy wait long2 for just normal tests.

IBT? details plz, if its tat fast of detection, i would lurve to try it too!

fast not ensure stability..real helpful if u still process of finding the max/wall..

intel burn test.. google it..
if normal stress.. usually i make it around 10loop.. if max stress..means use alot of Ram, only 5loop..
depends on u la..

just a reminder.. system might pass IBT but not sure will pas Prime..

but bro athlon is ryte, we run the fast way first, thn we go priming, if IBT fails, no need to prime, hav to tweak 1st smile.gif

yeah.. but 1 weakness..unable to stress either ram or CPU..all stressed at once.. i think la..since no option to change..if isolate wont be a prob la..

btw..correct me if im wrong then..

haha ur ryte, priming can isolate problems based on the settings, but some people argue the best stress program for heat output is linx...i think.....btw..correct me if im wrong then..
