CPU upgraded.

Hello,

I just replaced my 720QM for 920XM, installed since 30mins. Everything work great so far, the chip run cool. However, i was wondering if there anything i need to set/fix to get the maximum performance.

Thank you!

 

Throttlestop will unleash the potential for your 920XM. Good to hear your CPU upgrade was great success.

 

Sweet, ill look into this. Im excited .

 

Welcome to the extreme club.

 

Congratulations! I... will join you! Soon!

 

Cool! I think your laptop has a pretty good cooling system, if I remember correctly...
You should be able to run it with a 24x multi across all cores.

Now is there anybody who still wants a SB CPU?

 

I'd love the battery life but no way can afford another brand with an MXM slot

 

I got a question regarding ThrottleStop on the 920XM. I have ran different setup of TDC & TDP and multiplier and i dont see much of an improvement with the benchmark. My 920xm is OEM.

Stock TDC & TDP are 55/49 with 24/23/17/17 multipliers.

Tested with :
1- 70/49 24/23/17/17
2- 55/49 24/23/19/19
3- 70/49 24/23/19/19

Max temps around 85C with the throttlestop benchmark (32m).
Anyone with the 920xm can share his setup?

 

Stock is 55/49 TDP/TDC? I think I had 62/62... maybe the ES version differs from the OEM.

I can't remember my settings, I can check it when I'm at my machine if you like, but the you'll definitely have to increase the TDP/TDC for running a 24 multi across four cores (yes, get them up too )

I think I have something like 88/80 for TDP/TDC. You can push the multi to 26 or more for one core.

Look around on the Alienware forums, there's a thread on this and you'll be able to find the settings of the other 920xm users.


Max temp at 85C isn't too bad when you do some benching or prime95 tests...

 

What range of temps is safe? Isnt bad to push the chip over 90-95C?

 

You will get a BSOD when pushing too hard, as the cpu will shut itself down to prevent harm when the temp reaches 100°C.

But I never get such high temps unless I'm pushing it with wPrime or similar... When you test different settings with Throttlestop just keep an eye on your temps. You can even set an alarm for a certain temp with TS.

 

Yep im watching my temps very carefully. I wonder if the temps display in TS stop at 100C because i got the same temps with much higher setup.

I tried both TS and SetFSB at the same time, however i didnt pushed the FSB too much, from 153 to 165.

I had BSOD at 26 multipliers. Definetly temps issues... I wonder how i can fix that.

 

No need to use setFSB, Throttlestop is more than enough. Anyway, baseclock is clock is 133, not 153?

Assuming the G73JH has the same or at least similar good cooling system as the G73JW I really think you have to reapply the paste. Maybe you accidentaly got some little air bubbles between CPU and heatsink.

Also check for dust inside the laptop and make sure nothing's clogged. Try getting some more space between the bottom of your laptop (where the air gets in) and your desk, for example by raising the back of your system with a book (make sure you don't block the vents).


You could also compare your temps to other G73 users with a 920xm, I'm sure there are a couple of people at the Asus forum which can provide some advice which is more specific for your system.

 

Here's what's possible if you can keep the core temperatures from getting too hot.



This is a pic of a 940XM. Nice work 5150Joker.

26 across the board even when fully loaded.

 

Its 153 with turbo on (get fsb). JW should have the same cooling setup.
Ill redo the repaste again but im pretty sure i did it fine on my second repaste, i even cleaned the fan with an air can. It take quite some time to repaste . Oh well...

That is very nice performance. On a side note, in TS the set multiplier (not TRL) goes from 9x,...,15x and then turbo. I can see in this pic 5150joker set his at 17x.

EDIT: I tried to run wprime with twinturbo mode disabled and my temperature seem to be lower and i still got the same speed. 100C to 90C with 26/26/26/26 and 95/75

 

On the Core i processors, for full turbo boost, Set Multiplier needs to be set to 1 more than the default multiplier for the CPU. The default for the 920XM is 15 so Set Multiplier needs to be 16. The 940XM is a default of 16 so Set Multiplier needs to be 17. This is how the CPU works internally.

Many users didn't understand this so instead of using the +1 I decided to call that request Turbo because that's what you're actually doing. You're requesting full turbo boost. The TRL Turbo Ratio Limits window controls how many bins of turbo boost you get depending on how many cores are in the active state.

This is a little confusing because Turbo Boost is something Intel added on to their original design so the regular multiplier and the turbo multiplier are completely separate internally and need to be adjusted separately in ThrottleStop. It kind of makes sense after you play with TS for a while.

When your CPU is allowed to hit 100C, it will start throttling and instantly kill performance. Its hard to make a fair comparison of settings when thermal throttling is randomly kicking in and out.

 

Thanks for the explanation, now i understand how this work.

 

How much hotter does the 920xm run than the 720qm? I'm considering upgrading as well, but I need to know if my cooling system can handle it.

 

If your sys is the Y560 I doubt it'll be able to handle it; just based on what I've read about that particular laptop's mediocre cooling potency.

 

To run a quad-core extreme processor, you'll need more than good thermal paste. I'm suggesting doing copper mod (copper shim) to the heatsink (between the CPU & the heatsink).

 

That only works if poor contact is the reason for poor cooling.

 

FWIW, it is already proven to works though. I have not read anyone tried it on i7 extreme processor but there is already people tried it with i7 quad-core processor. Dropped the temperature around 10C. It should help cooling down extreme processor too.

 

It will be model and heatsink specific, but if someone has done it already and it helped then obviously there is an issue with contact on this model.

 

Sounds easy enough and I'd like to improve my cooling anyways if possible, does anyone know where to buy a thin copper shim?

 

What in syberia? Not a clue

International forum remember. Where do you live?

 

eBay maybe. You'll need to know the dimension & thickness. You don't want too thick because you don't want to damaged the CPU & chipset. It should be enough room for thermal paste too. I don't have experience on this mod, so sorry I can't be much more help. You can take a look at this post for pictures of the heatsink, before & after mod - as an example. If you can find the seller, ask them if they have any for your notebook. If they don't have, ask them if they are willing to make one. It is not too difficult to them, they just cut it according to your measurement/dimension. This method has been used years on desktops & laptops. It's effectiveness is depend on how good you do it though.
