When i wan to go further n adjust 1.335>1.350, my pc fail to boot, after POST i got a black screen with underscore on top left screen. 1mo is i seen u guys oc with gaming ram, is it related to oc cpu? My ram is kvr 4gb ddr3 1333mhz, i leave it at stock speed currently.

the only effect is it will let u run higher speed.
risk is blow upĀ  biggrin.gif

Nice, but not a good proc. Temp is that high due to hot weather in msia.
ur vcore during load is actually 1.41v.

Ya, the temp is a bit high, so i roll back to my previous solid hard rock 4.6ghz, only max 74c while running 50x linx. And i found my 4.8ghz is not stable yet, even i ran 50x linx and 1hour prime95, after that i just open winamp listen music and viewing picture in my folder den blue screen.

U knw TMPIN0 temp is from which system component? It hits 79c lol.

U will get higher GFlops on HT off coz 4 extra threads hv to run on the same amount of cores.

So mean 8 thread i7 2600k will get more GFlops? My i5 2500k 4 thread with 90+ GFlops is acceptable right?

aiyo, look clearly what owikh said  doh.gif , he mean ht off will get higher GFlops

please show us a full info about your setting, use cpuz to show cpu clock speed, ram clock speed etc. hard to judge ,because you only show a linx screenshot.

Downclocked to 4.5GHz due to high room temp sad.gif


Added on April 8, 2011, 8:48 pmis it latest LinX much stressful? It feels like after trying latest Linx i only got such high temp. sad.gif


Added on April 8, 2011, 9:07 pmuser posted image

I test back the previous 0.6.4 linx, i found the previous version takes longer time to complete each task, latest version takes 50sec high GFlops, previous takes 110sec low GFlops, its means latest version is really much stressful, it squeeze every juice of my cpu to work, tats why more heats is created.

now i knew my h70 not tat sux actually , last time was surprise because saw you all using hyper 212 clock at 4.5ghz and get same temperature with my h70.

@firagaz, can you show you ram speed? cause i also clock at 4.5ghz now, how come i can get 124gflop but you only get 95gflop

2500K should be producing the same GFlops, unless CPU throttling.

what mean CPU throttling?

I'm running daily i5 2500k 4.5Ghz at around 1.38V for stable =.=
I think my voltage too high .... but if decrease will having bdos 12~24 hours late .... how to improve it >.<

do u enable internal pll voltage? try disable can try again, mine last time enable 4.5GHz need 1.35v, but after disable i can run it at 1.325v.
