Problem After CPU Upgrade

Hey guys,
So I bought an Asus G51VX and have been perfectly happy with it. However, many games coming out require a better processor than the stock, so I purchased an Intel T9600 Dual Core(this version of the G51 doesn't support Quad Cores, I believe).

Anyway, I received the CPU, and installed it with no difficulty. The computer runs just fine, normally, but anytime I try to run a game, the system only lasts for a few minutes before shutting down. It's entirely possible that this is a heating issue, but I've applied thermal grease to the new unit and bought a cooling pad, AND undervolted, so I'm not quite sure what other steps to take to mitigate overheating.

If it's some different problem that I might not be aware of I'd be interested to hear it. I suppose the GPU might be overheating as well, but I didn't have that problem with the stock 2.0 ghz dual core. I overclocked the original core without overheating issues, so, yeah...I'm kinda stuck. Any help would be appreciated!

 

Blakery, if you are not getting any blue screen, do you notice any entries in event viewer related to the shutdowns?
Also are you using Hwinfo32 or hwinfo64 to check CPU and GPU temps?

I have same laptop as you and in my lap there is Intel E8435 55W version. I have also changed tim and undervolted it, but there is no mods done on laptop and still is not overheating. Max temps I was able to see were around 85C playing Crysis. Make sure you download some monitoring temp tools and check it. Something is overheating, but may or may not be cpu, could be gpu or you just didnt apply enough paste or screws are not all in.

 

but, did you use the rice grain method?

Is your AC Adaptor working properly and at the proper power output for your system's new minimum requirements?

 

Good Question! maybe with a higher TDP you need a higher amp supply.

 

Considering Dragan said he has the same notebook and it using a 55W TDP CPU, a 35W one wouldn't require a new PSU, especially because IIRC these notebooks were sold with Q9000's and Txxx series.

 

If it were a PSU problem the PSU would cut out and it'd default to battery power. Also I believe the quadcore laptops from this series shipped with a 150W adapter (instead of the stock 120W). I OC a 260m and an E8335 with no issues on the G50vt (same chassis/PSU/mobo).

As people said before, check temps, your paste application, and that all heatsinks are making full contact with their respective parts.

 

yeah make sure you use the proper method of applying paste, not spreading it out and use something like HWmonitor.

 

Hn. Well, since the system lasted all of 15 seconds in a stress test and I saw temps over 90C I'm pretty sure it's a heat problem.

So. Just so I'm sure, what's the proper method of applying paste? I'm fairly new at swapping out CPU's so it's entirely possible I did that entirely incorrectly. Other than that though, I am currently undervolted(although I can always do more) and have a cooling pad; what else can I do to help mitigate the heat?

Do a search on Google. Basically find a good thermal paste, I use Noctua NH-H1. Basically, remove any old rest from the heatsink with some cleaning tool for example ArctiClean™. You can also use some pure alcohol. Apply just a little dot on the center of CPU then tighten the screws from 1.2.3.4. As I said, a quick google or youtube search will give you plenty of results to start with.
