omega939 Posted January 6, 2014 Share Posted January 6, 2014 I have question regarding my AC adapter or thermal heat related issue. Whenever I benchmark my gpu (nvidia gtx 680M) with 3dmark 2013 and using afterburner (tweaking to high core clocks and memory clock settings), it loads but after loading my notebook shuts down... Is my PSU lacking in power? Or related to heat issue? That's why it shuts down. I am using a 240 watts ac adapter, vbios mod by svl7 (1.025v), ec firmware mod and unlock bios. Its not heat related because I just cleaned my gpu/cpu heatsink fan and put a xigmatek PTI-G4512 thermal paste. I did also run a memtest to check if its a faulty memory but did 4 passes with no issue.I am opting to buy a 330watts dell adapter if my 240watts psu is lacking power now as I saw in one of the post of meaker in another forum.Can anyone help? thanks Quote Link to comment Share on other sites More sharing options...
cresterk Posted January 6, 2014 Share Posted January 6, 2014 I doubt that it is due to the psu as I have gone above 1.075V on the default one without any probs except heat. Msi afterburner shows your temps on the side, check if it goes above 90C Quote Link to comment Share on other sites More sharing options...

Only a very overclocked sandy bridge could trip a 240W PSU with a 680m at 1.025V. If so I would expect the combined test to cause a PSU shutdown. If you're getting shutdowns during just the graphics tests then power is not your problem. Also if you were having PSU shutdowns you can tell because you need to disconnected the PSU for over 5 seconds to get it to turn back on, assuming you are using the dell m17x 240W psu.

Locked multiplier but still oc'ed fsb + oc'ed GPU 680m @ 1.025v.. So my psu cant handle the load? thanks mateAlso if you were having PSU shutdowns you can tell because you need to disconnected the PSU for over 5 seconds to get it to turn back on, assuming you are using the dell m17x 240W psu.<!-- google_ad_section_end -->When shutdown occurs, I can turn on the power button instantly... dunno if its heat issue, but if its heat issue, first the benchmark will still run then, artifacts, then exit in 3dmark right?

BCLK is weird and results in hard freezes/shutdowns when too high. If dropping the BCLK isn't it, then I say your GPU overclock is just too high.The PSU is definitely not the problem. 1 Quote Link to comment Share on other sites More sharing options...

Many thanksYour gpu OC doesnt seem to be that high. Just lower the bclk like khenglish said. Quote Link to comment Share on other sites More sharing options...

BCLK is weird and results in hard freezes/shutdowns when too high. If dropping the BCLK isn't it, then I say your GPU overclock is just too high. You where right with your diagnostics.. First and foremest, 3Dmark 13 with the updated version of V1.2.25 is so sensitive with BCLK. I lowered the bclk from 105 to 103 and it did work! No more shutdown. Your second advice is, I've checked my mxm board (took out the board from my nb and attached it to the heatsink to see if the thermal pads are doing its job) and found out that there where 2 thermal pads attached to the capacitor but it's not in contact with the gpu heatsink which I've put additional pads just to fill those gaps (thus leads to a more lower temps) I updated the vbios from v1.025 to 1.05v and it gave my 680M more juice!!! Here's the pic of 3dmark 11 benchmark @ 105 fsb I think futuremark should make another patch with 3dmark 2013 regarding the BCLK issue. Because before I updated to the latest version (V1.2.25), all is working well, Just like 3dmark 11. Both can run 105fsb with no issues/shutdown. Anyway, thanks mate :-D Quote Link to comment Share on other sites More sharing options...
Bishop1981 Posted January 11, 2014 Share Posted January 11, 2014 the problem is fsb of cpu , go back to fsb 100mhz and will work 3dmark, Quote Link to comment Share on other sites More sharing options...
omega939 Posted January 13, 2014 Author Share Posted January 13, 2014 the problem is fsb of cpu , go back to fsb 100mhz and will work 3dmark,<!-- google_ad_section_end -->@ 103fsb both 3dmark 11 and 13 are working flawlessly. Anyway thanks for the advice. Quote Link to comment Share on other sites More sharing options...
