One way to find if it's the NB.
Blast a load of volts into it, if the temp raises dramatically, it is.
And I think my Thuban's faulty.
Sometimes it takes a load really well, other times the temp goes up 1c a second till it BSOD'd.
Right now for example, priming, I'm at 43c.. And I have been for half an hour.
 
:eek::eek::eek:

running cinebench and my score has gone down .... despite me upping the NB ... I get the feeling i just wasted 8 hours priming the NB when perhaps theres nothing to gain but high temps..

TMPIN1 reached 49C and TMPIN2 reached 54C when running cinebench unless that borked the results

EDIT .. phew must have been HWMonitor causing it to glitch as speed has gone up re running :)

not sure the gains are worth the pains

I'm probably going to invest more money into the air flow in my HAF 932..
But anyways.

I'm running 3260MHZ on the core, 2600MHZ on the HT and 2600MHZ on the NB.
My RAM's running 1740MHZ at 8-8-8-24-25-1T
Temps at 46c on the CPU.
 
OK upped NB to 1.4v

HWMonitor is reporting

TMPIN1 low 34C high 52C
TMPIN2 low 42C high 66C

doing IBT for 10 runs high on run 7

fifnished 10 runs with max temps TMPIN1 = 52C TMPIN2 = 67C

so no idea if that proves anything .. lol

EDIT
reverse engineering ... NB @2800 1.3v 10 runs of IBT high and max temps TMPIN1 = 51C TMPIN2 = 65C

Conclusion ... INCONCLUSIVE .. lmao .. nb volts dont seem make much difference to TMPIN2 but they do make a small difference

1.55v :eek::eek::eek::eek::eek:

think i will reverse first and back down NB to 2600 and see if things drop more ...

guess the big question is .. if its the NB .. what is a safe operating temp
 
so far

NB 3000 @ 1.37v - max TMPIN2 70C after 8 hours prime ram [email protected]
NB 3000 @ 1.40v - max TMPIN2 67C after 10 runs IBT high ram [email protected]
NB 2800 @ 1.30v - max TMPIN2 65C after 10 runs IBT high ram [email protected]
NB 2600 @ 1.25v - max TMPIN2 65C after 10 runs IBT high ram [email protected]

soooooo analyse that ... lmao

upping ram voltage but lowering NB voltage gives same T2 temps :confused:

personal comment ... windows felt more responsive with NB@2600 than it did NB@3000 when first booted
 
perhaps we are being overconcerned as nobody else seems to even mention temps (or prove their temps) on places like xtreme

some claim to have 4.2Ghz on 1.42v with NB at 3.2Ghz on 1.25v at temps of less than 50C with air coolers but they dont show temps either core or cpu on their screenies and none even mention NB temps

seems i may have a badish chip as everyone else gets 4Ghz on much less vcore than me .. unless my ram was boogieing my early tests up

will have to try dropping my vcore and see if that lowers TMPIN2
 
well having lowered vcore to 1.42v peaking in HWMonitor @1.44 and dropping NB to 2600 @1.225v my temps are now

TMPIN1 = 50C max
TMPIN2 = 63C max

IBT high 20 runs with ram [email protected] so i wonder if T2 is a combination NB and IMC (sort of same thing anyway) .. minor temp 4C changes despite dropping from 1.4 to 1.225v or maybe southbridge with my case cooling not so good

someone bash me on the head .... :rolleyes:

checking back through my own screenies ... @stock NB and NBvolts my TMPIN2 was still peaking @62C .. so would appear its my system that has a high reading and a 3Ghz NB only adds 8C to it and thats after 8 hours+ priming

going on those figures I cant imagine the TMPIN2 is going to affect stability so only concern is if it affects the cpu life expectancy

thats my spin on it anyway ...

nice score martini ... beats my effort ... sort of .. though I have slower ram

so your NB is slower but ram is quicker .. does that mean a high NB isnt needed ?

Im away from home and thus my 1090T, only had weds evening to play with it :(

But its been good reading everyone progress, gonna have a play with some combinations of clock speed/ nb clock see how it affects performance.

I was finding that OCing to 4 GHz wasnt really doing much but hopefully upping the NB will.

Obviously I could try myself, but what sort of clock on the NB should I aim for with a 4 GHz cpu clock. Read somewhere about within 1.2 GHz? so what 2.8 GHz NB?
