Overclocking G73JH using 920xm

Boy this forum has changed! I'm one of the few that did the 7970m mod on my G73JH, and after a couple years finally got around to doing a 920xm upgrade. However, I am having some issues overclocking it. I'm hoping some of the old school people are still around to answer a few questions.

I found several guides, the problem I have though, and this could most likely be a user issue, when I set Throttlestop to the correct settings, multiplier never goes beyond 17x. I am currently following this guide

http://forum.notebookreview.com/forums/asus-gaming-notebook-forum.1087/create-thread

I can follow the guide but I am unable to see the CPU go above 2200mhz when benchmarked. I was hoping to see a few screen shots of how this guide had the settings but the images no longer exist.

Anyone share some light?

 

Can you run xtu? It could help you indentify the problem as it gives good information about what is causing throttle.

 

XTU? Not sure if I'm familiar with that word. Can you elaborate?

 

Extreme tuning Utility, it's a program made by Intel for the purpose of overclocking their CPUs.

I used to own a G73JH with a 920XM and if you are running off the stock power supply, it might be an issue of power supplied. I can't however remember what the TDP and TDC settings I used were, it should be somewhere in one of the G73JH threads though.

IIRC, I had to crank the TDP quite high to hit ~3 GHz, in the >90W range. Even if you change the multipliers, you will also need to change the TDP and TDC settings somewhat to allow the CPU to draw more current and dissipate more heat. Be warned though, you may end up limited by the power supplied by the motherboard and/or PSU and not be able to hit more than a certain clock speed.

 

Fascinating. Out of curiosity, did you have a 7970m?
So with XTU, do I not need Throttlestop? Note that I am NOT using the stock power adapter. I immediately got a higher one when I upgraded. I don't remember the wattae, 280 I think or 240? I'm at work so I can't check right now.

My understanding is, you set the multipliers, like 25 25 25 25 or whatever, check Turbo Mode, set TDP and then turn on throttlestop, but the multiplier as indicated in throttlestop is still at 13 or some low number.

 

Just got home from work. I don't get why I can't overclock this processor. I am using the latest modified bios that I got from here. I downloaded XTU, temps are below 60''c. I attempted to overclock with XTU to no avail. System fluctuates in speed, 2.6 to below 2ghz. Seems to like 2ghz for whatever reason.

I don't know what to do. Could someone share some lights? Does this have to do with BD Prochot?

 

How about post some screenshots? If the CPU multiplier in the 920XM is not reaching the maximum amount when fully loaded, it is likely because the values you are using for TDP and TDC are too low. You need to increase those limits so the CPU gets enough power so it can run at full speed. The Dell laptops of this era seemed to have better cooling so could be pushed harder before the CPU got too hot. Heat is usually what limits you. Keep raising TDP TDC until your temps get too high.

 

As UncleWebb said, raise the TDP/TDC values and also I would say increase the voltage slightly.. I think it's power starvation which is causing the clocks to fluctuate..

 

Thanks guy for your input, I did that and it still was not overclocking however, I did got into the modified bios, there was an option there that said "enable extreme edition", after doing so, the computer allowed me to change the multiplier. I increased the TDP/TDC values but I am a little confuse as to how much and what the ration is between the 2. I did something like 90/75 with a speed of 3ghz, when running prime, temps reached 100'c and it throttled back down to like 2.6ghz. I am assuming that is because of the heat. When I ran 3dMark, which is significantly less heat intensive, it stayed at 3ghz the whole time.

Is there a way to fully disable throttle control? I bought some ram heatsinks, I plan to add them to the heatpipe of the CPU.

I'll post a picture after work

 

The throttle is built into the CPU and is there for a reason You want that working at that level.

 

svl7 showed just how much performance is available from the 920XM if you can find a way to keep it cool.

With proper cooling, it is a beast of a chip. Time to repaste your CPU with the best thermal paste money can buy, add some more copper to the heatsink and do whatever it takes to unleash the beast.

 

Well adding more copper wont help unless you apply airflow to it, but i've seen adding heatpipes help

 

I was going to add more copper an drill some holes from below the heatpipe to allow air form the cooling pad to enter.
Also, seem as if it will only throttle down when I prime95 it, temps do get quite warm, about 100'c. However, if I just play games, it hovers around 80'c

 

Prime is designed as a greater than normal load stress test.

 

i'm strapping one of these to my G73JH,
