Anyway to stop "throttling" on 720qm and have iut run max speed? 7970m bottlenecking!

After hours of reading and tweaking I finally came across a thread that said there is no way to run a 720qm at max speed without being throttled because it has a locked multiplier. A lot of time wasted and some what frustrated grrr lol. I've played with Throttlestop and SetFSB

My only option is to either buy a 920xm/940xm or use setfsb correct?

I've used SETFSB payed version and I don'tget much performance gain. If anything I lost performance. Probably to do with the throttling.

Reason I run to run my CPU at max speed is because the throttling is killing my GPU. When I play games like BF4, GPU bottlenecks because of the throttle. It's virtually un playable.

I have the latest unofficial bios (G73jh.213.Moddedv5) provided by individuals here in these forums and I have a 7970m installed on it as well.

What are my options?

Have you checked your temps? The CPU might be throttling because of that.. I used to run my 740QM OCed and had no issues..

 

I concur with Tom. It will not throttle down unless temps are too high. 99% of the time is the temps. Or your 7970m could be tripping power so cpu and gpu both throttles down.

You HAVE to check this before a 920xm which outputs 10w more heat and uses a lot more power.

Prime95 & furmark test individually for gpu + cpu max temps. Next, run 7 threads of prime 95 and run furmark for the gpu TOGETHER. That will essentially max out both components.

Have Realtemp and GPUZ installed to see the temps of the components and if they throttle down at any point!

 

Did you try and untick BD Prochot in ThrottleStop?

 

If you want to stop bottlenecking your 7970M you'll need an XM overclocked to 3.5 Ghz or higher. The stock clocks on the Clarksfield i7 are stupidly low. My 740QM ran at 1.86 GHz in games. It was shameful.

 

Temps rarely ever exceeds 80 degrees on both CPU and GPU, they run very cool for the most part. I've read multiple threads that a 720qm will most certainly bottleneck the CPU because of the throttling. Don't see any reason why the GPU would be tripping (lol get it? its tripping xD) I mean, even when I had the 5870 the CPU was constantly doing its thing of playing with itself frequency wise.

Yes I have, very cool is what they run, rarely ever exceeding 80 degrees. I live in San Diego so temps are rarely ever too hot or too cold.

Yes I have that option available in the modded bios and in the software itselfs, "trottle stop". But when I disable throttle, it goes down to a multiplier of 13, which is 1600mhz. Does me no good.

That
s exactly what's going on with me, it running at a low frequency. Even in 3dmark, I am constantly getting either 100 higher schore or 100 lower score. Extremely shameful. So what your saying is, as other threads have suggested it, I need a 920/940 xm cpu? No way around it? If so, I see on ebay a 940 is around 300 bucks while the 920 is 170. Almost twice as much. Is the 940 worth the extra money?

 

and what happens if you disable prochot in the bios?

 

Get a 920XM since it's much cheaper and overclock the hell out of it. :thumbsup:

 

He kinda did not answer my same question to that. Also he dont mention what clocks 720qm downthrottle to it. And he cannot expect to have max turbo on all 4 cores under load on all of them. I dont remember now bu it is like with load on 4 cores multiplier is @13 =1,73ghz if he expect more then that then he is wrong. 2,8ghz is only achieved with load on 1 core.

 

well if it does the same thing i might actually start to suspect the CPU it's self, i've seen it before... well not in this specific case but, i have seen CPUs go wonky before.

 

Nothing as far as I could tell. I think it was intended for the XM cpu's. I need to use the software to enable the throttling but it sets itself to its default multiplier which is 13. ;/

Can the 920 achieve the same clock speeds as a 940? That does make sense though.

1600 or 1700 whatever the default is. What it stays at ;/ The who trubo concept is stupid. Causes so much head aches.

XM it is then.

 

all assuming it's not your power brick! i've seen PSUs do funky stuff from time to time. IF you have money to spend compliment that XM with wither better power brick. get a power brick form another laptop with more watts at the same volts and mod on the correct tip or cable to fit your laptop.

 

What are your power settings at?

 

I don't think so, I am using a Dell AC adapter, J938H, rated at 240w. Got it to accommodate the 7970.

Performance/High

Another thing I just found out, I get more FPS when I overclock using SETFSB, however when I play BF4, I start getting micro stutters, almost as if I was lagging because of high ping. When I set overclock settings to normal, stuttering goes away.
Frustrating, the more CPU intensive game the more lag I get. I guess I really do need a 920xm. To make matters worse I blew my desktop motherboard lol.

 

well then unless there is weird defect in you power brick it seems you are already ahead of the game there!

Well if you weren't over clocking i've seen those symptoms in faulty CPUs. I guess we will see what the XM does for you?

 

The only difference between 920XM and 940XM is one multiplier, and you'd be overclocking anyway, so of course whichever one is cheaper is the better buy.

You're not gonna be getting any worthwhile overclocks out of increasing FSB at the risk of destabilizing your entire system, so just get an XM and up the multi. Sounds like your current setting is unstable or you might have to futz with the RAM.

 

Then there is nothing wrong with your cpu. 1700mhz on all cores is what you gey from that cpu. 920xm has unlocked multiplier so it is only thermal limit that is roof.

 

so we all kind of dropped the ball with out thinking? at least i feel i did.

 

I didn't. I've owned a 740QM before and I know how ridiculously low the clock speed is. 1.86 GHz x 4 is a joke. Two years and tick-tock-tick later and the 3630QM does 3.2 GHz x 4 plus 20% IPC improvement makes it easily over 100% faster at the same TDP.

 

What are the symptoms of a bad brick? I do get occasional restarts and the brick does get warm even when the system is just sitting doing nothing or in sleep mode. I always associated that problem with the unofficial 7970m mod. The area where I have the cable taped up, where I spliced together the old asus connection to the new ac adapter does get very warm. I've checked the cables several times, their not making contact with one another. To be honest I don't know anything besides the tapes area getting warm and the ac adapter.

Oddly enough, when the system crashes, it's never when I am playing a high intensive game like BF4, it's when I play League of Legends, not CPU or GPU intensive, so ?

I think that's what's going on, system getting stupider when overclocked through FSB. How would the multiplier work though? Do I use setfsb for that?

Always though this cpu was a little gey. I'll buy some small copper heatsink and paste it around inside the copper heat pipe. It's over do for it.If I get the XM, this laptop should last a couple more years. Even if somethign breaks like the mobo, definitely worth fixing.

Know the feeling ugh 1700 ;/ XM go for about 170 I think I am going to buy it. Have to get my desktop working first. I blew the motherboard lol OC'ed it too much

 

Double post ;/

 

Copper shims wont help you only good cooling upgrade would be adding extra heatpipe along with existing. Or upgrading cooling fan. All other copper mods are just placebo effect.

 

With the XM just keep BCLK at 133 MHz and increase the multiplier one step at a time through ThrottleStop or BIOS (if unlocked). Stability test w/Prime95 between increments. You should easily be able to get above 3 GHz on stock voltage unless your sample is a dud. Increasing voltage will allow you to go higher but requires a physical pin mod and a cooling overhaul to cope with the substantially higher temps.

 

Wasn't talking about copper shims. I would place small copper heatsinks all around the heat pipe. I did this for the video card heatsink, it did bring down the temps

I do have the modded 2.13 v5 bios, could I overclock through bios? I see a lot of features...

 

See if the modded BIOS has options to change multiplier and voltage.

 

so is this a an Asus G73 we are talking about?

 

Read the OP.
