Hello,
i wonder if i find somebody experienced which will be able to help me with following problem. I have laptop G74SX-TZ195V which originaly came with Intel Core i5 2430M. I upgraded this laptop with CPU Intel Core i7 2760QM.
- To ensure that i will keep temperatures down i used collaboratory liquid metal pads for notebooks and temperatures never crossed 69 celsius (under CPU and GPU load - for example tried with Crysis 3 or Starcraft 2 HOS 200units and Ultra detail settings, FURMARK, windows experience index, F1 2013) but failed with shut down OF PSU.
-laptop originaly came with 120W PSU
which i already exchanged for 150W PSU (genuine part for G74SX) unfortunately PSU exchange did not solve problem which appeared on previous PSU either - shut down under high load.
CPU have turbo boost feature from 2,4-3,5GHz and i noticed during testing when i limited multiplier with Throttlestop to 27T (2,7GHz) computer was able to run pretty stable, but everything basicaly from 2,8 - 3,5GHz was unstable and from unknown reason caused PSU shut down - yes PSU not laptop! (with battery plugged laptop keep running) - temperatures not higher than 69, GPU not overclocked. I estimate that some of the safety mechanics on motherboard purposely shortcuting PSU circuit which causing his shut down.
iam using modified BIOS from this thread (G74SX_AES_Throttle-Fix.zip)
