Asus G73Jh 920/940XM Multiplier & TDP/TDC values

Please can people with an Extreme Mobile Core i7 processor let me know what multiplier & TDP/TDC values that they are running, and if they are using any additional cooling to keep their temperatures down.

I am running my OEM SLBLW i7-920XM in my G73Jh at 75W TDP with multipliers of 28/28/26/26. On full load, using Prime95 and RealTemp, I get 2.53GHz (19x) on all four cores, and get right up to just before TJmax, with a peak HWiNFO32 CPU power draw of 80W.

I only fully load my CPU when I am running Anti-Virus software, or during compilation or synthesis of my code, so my G73 runs quietly the rest of the time with core temps in the high 40s & low 50s.

 

Hi, here is my settings with stock cooling. This is as high as i could go while being stable for hours at 25C ambient temp.

TDP 78W
TDC 49A
Ratios: 28,28,23,19 (Completely stable after many hours at full load)
CPU core temp max 85C

Yours is throttling down to the same multiplier as have at 4 cores (19x) so there is really not necessary to set the multipliers that high.

First i used Arctic Silver 5. After repasting with AS5 two times i tried ICD7 and got better result. Mostly because it is much easier to apply correctly i think.

Cheers

 

Thanks. 75-80W seems to be the maximum TDP for the G73 with standard cooling, so I think I will leave my settings as they are, and let the BIOS and the ACPI do the throttling. I did not know what to set my TDC to, so I set it to 67A, which is an increase of 20 from the stock values (55W/47A).

From what I have read, the maximum TDP seems to be around 105-110W, and is limited by the 175-176W maximum power draw of the G73 motherboard. This requires extreme cooling, so seems to be for the very bravest people only.

It might be useful in the future to get some sort of notebook cooler or refrigeration system, and raise temporarily my TDC/TDP values via throttlestop, to get more performance out of my system when it is required. For the moment, a fast SSD is going to make a bigger difference in performance than anything else.

 

I'm satisfied with the result. It's almost 1GHz up from the 720QM.

Here's a cooling solution for you. If your brave enough

Can you change the multipliers etc in BIOS? I cant find any settings. The reason could well be that i have an ES processor.

 

u might want to get a 180W targus universal PSU so u can OC more.. the 150W adapter for G73 isn't enough.

 

The Power Supply is sufficient as long as i'm overclocking with stock cooling.

 

There is an Extreme Edition menu in the G73 BIOS under Advanced->CPU Configuration->Power&Performance. This should work with the Extreme ES processors as well as with the OEM ones. Soviet Sunrise posted a dissertation somewhere about the 920XM Q3B8 ES processor being hotter and less stable at high temps than the 920XM SLBLW OEM processor, but the 940XM Q4AP ES processor has been reported as being ok.

The overclocking menu allows you to set up the maximum allowed multipliers and TDC&TDP values. You can also use Eleet, ThrottleStop and SetFSB to overclock, but these need to be run every time you load Windows, so it is easier to set everything up in the BIOS and let the ACPI handle everything.

I also have the Targus 180W PSU, which is more useful than the standard 150W PSU, since it has a right angled plug and spare tips for other notebooks.

 

i got a 920xm but when i try to change the settings in the bios for a mild overclock when i boot it will stay stuck a 2 ghz no turbo boost what can it be??
i have the eleet tune and it overclock ok with that.

 

The Turbo Boost has been disabled, so your 920XM is running at the stock speed of 2GHz. You may have disabled accidentally the Turbo Mode option in the BIOS.

Otherwise the TDC & TDP values are in increments of 0.125, so the default TDC & TDP values of 47A & 55W are 376 & 440 in the Extreme Edition menu (bitshift by 3 or multiply by 8)

 

its enable because if it was not i cant change the multipliers in the bios, and i dont us the turbo mode. the problems is when i activate the extreme mode in the bios that lets me change the multi when it boots up in os it stays stuck in 2 ghz like if i disabled turbo but its activated.

 

Have you tried changing the TDC & TDP values in the Extreme Edition menu?

The stock settings for the 920XM in the Extreme Edition menu should be:
376,440,24,23,17,17.

 

ok my bad thats where i went wrong i set the tdc & tdp all wrong. thank you alot for explaining. so how do i set the tdc and tdp to start throttel at 85c?

 

You need to experiment with different TDC & TDP values, and monitor your core temperatures, using programs such as HWiNFO32, ThrottleStop and the Argus Monitor, whilst stressing your CPU using programs such as Prime95 & RealTemp. Throttlestop lets you change your TDC&TDP values on the fly, so you do not need to reboot everytime.

I think the limit of the G73, using standard cooling and a decent thermal compound, is around 75-80W TDP, so a 70W TDP should achieve a max temp of around 85 degrees. This should give around 2.4GHz on all 4 cores under full load.

 

got any game benchmarks or anything with it running at max O/C?

 

Use Throttlestop. You have the ability to use multiple "speed" profiles. You can set a maximum CPU temp, when it's reached Throttlestop switches profile and downclock until temp goes under your preset max temp then switches up again. Very nice feature.

 

There is no increase in FPS since the bottleneck in games is the GPU. The CPU is plenty enough at stock speed. However in applications like Digital Photo Professional (converting raw images), video encoding etc which are heavy CPU dependent there is a quite noticable gain. Which benchmark are you interested in?

 

Just checking to see if the 5870 would scale at all with a faster cpu, guess not.

 

Thank you all for the help.

 

Does anyone got the 940's bus/core ratio? Is 25/24/18/16 correct?

 

I think it is 25/24/18/18.

 

e-leet tells me the same but it would be very helpful if somebody could give me an official link. There is absolutely no problem finding this information for the 920 but it is for the 940.

Additionally, if the laptop suddenly switches off without any warning it would mostly because of a weak PSU, right? (CPU: 85C max, VGA not oc)

 

See List of Intel Core i7 microprocessors - Wikipedia, the free encyclopedia

 

Thank you.
Intel could release this relevant info on their ark.intel websites though (imo)

 

Ok somebody please help me. I just got my 940xm a couple days ago. It is the es version. is the cpu option under advanced not there? Anybody think that Asus failed to incorporate the 940xm into the overclockable category? It would be nice to know anybody have some info I would highly appreciate it deployed in the sand box...

 

Wow, necro thread

You got a 940xm? Cool!! Best thing to overclock this is Throttlestop, that's all you need to release the beast. Check out the guide and feel free to ask if you have some specific questions.

 

Yeah, use throttlestop. It's easier to setup than to use the advanced option. Like svl7 said, thread necro, but at least you used the right thread .

 

Throttlestop is the way to go as Svl and Tijo said Neancell. It can and will make da beast go like it was made to go. Just watch your CPU temp go up

and up


and up





and up !!

 

Not with my G73


In my 213 bios I have't the last line "CPU CONFIGURATION" !



Is there a modded bios for 940 xm ES ?

Thanks for your help

 

It's not showing up on my G73JW either, mine has a 940XM ES.

 

Thanks Hackness, if you use ThrottleStop could you please show me pictures of your setup

Thanks for your reply

 

Hi, my G73JW is not with me at the moment, but I remember using 28 27 25 24 85W 65A. I used RWeverything to force the fans to run at full speed so max temp on 8 threads through the internal stress test tool on ThrottleStop is around 90C at the 15% mark.

 

90C is way to hot...you need to find a way to better cool that.

 

Ok thanks, whith my standard PSU (150w) my G73 hang sometime to time what PSU i'have to buy ? 180w or 200w ? pehaps little more ...

 

the 150w psu is fine as long as you dont through in a XM chip. You are hanging either because of OS/throttling/programs or something else. You need to lower your temps for sure.

if its regular OS/program hangs get an SSD that will make a night and day difference. they are now on sale below 1 dollar per gig

 

You do realise the normal temp for a 920XM/940XM at multiplier 24 on 4 cores is above 92C right? That's 3192MHz on each core

 

i run 3-3.33GHz with 85TDP/TDC and i get 80-90C with ambient temps. AC on It is 80C AC off its 90C. I am running a g51J with an abysmal cooling system that i have tweaked like no other. I am going with water cooling next if i can pull it off for 4GHz or more

 

I didn't put Ram heatsinks on my G73JW tho, without those the temp won't really go lower than 90C I guess.
