G73JH - 2Ghz from a 720QM

Before I claim I have the highest 720Qm CPU overclock on this forum and take over all of middle earth please feel free to contest against me.

I have a stable CPU overclock of 190PLL or 2Ghz and with turbo reaching 3.4Ghz and although my temps are pushing 5oC higher im seeing no glitches or issues so far.

If anyone can beat me I will begin creeping up from 190PLL.

Screenshot and my setup details shown below.

Let the contest begin! AT YOUR OWN RISK! :yes:

ADDED:

With SETFSB you simply raise the PLL and test every couple of mhz by using something like Prime 95 to make sure it does not lock up or BSOD. If you have the 720qm like me you will start at 139PLL or 153PLL depending if you have turbo mode on. Work your way up and as above you will gradually reach a point where things start not responding, gadgets and programs start crashing and you eventually BSOD. For me that is around 187PLL although my overclock ability as per my sig link of 2ghz is a lot higher than the norm and I usually hang around 185PLL to remain stable. Remember what your highest clock is and drop it down 4 or 5mhz once you have rebooted from the BSOD and then stress and test the PLL to make sure its stable, if not drop it a few more.

(SETFSB will reset back to default 139PLL if you crash or restart your computer)

IMPORTANT: have a read through this and apply this fix if you plan to o/c the CPU as Windows 7 has an adverse effect which needs correcting with a simple timing fix applied through DOS prompt using administrator settings. All compliments go to Unclewebb for this fix and his continued support with CPU overclocking.

Overclocks are limited by voltage and thanks to Asus it would appear because of hardwiring these cannot be changed so as long as you have good temps at the moment or good paste you wont really need to worry about the small increase in temperature, but use HWINFO to make sure everything is running as it should by using the sensors. Also every chip is different so do not expect to reach what others have or expect to reach more, as Tijo has explained on another recent overclocking post that chips are put through certain tests to make sure they can handle the stock clocks, voltage, watts, etc (called binning) and if they pass the tests they are allowed into the OEM production world, they do not necessarily test for the chip to reach the sort of output we aim for which in my case is excessive and im nearing the point of attaching a car battery to the GPU/CPU.

I posted this on another link I have amended it slightly. Remember overclock at your own risk as always.

 

I'd try it but I have no idea how to overclock. <3 Feels good.

 

You have the same model as me so yours might be mutant as well!

The temptation will get to you one day!

 

and right after my whole bios change ruining my overclock debacle.. this is like rubbing salt on an open wound *sniff*

Still congrats on the MONSTER oc.. doubt anyone will be able to beat it..
Did you do something different this time or you just hadn't dared to go so far before this..?

 

May I pretend I didnt see the "from a 720QM"

Nice job though. Im still trying to find out why my components suddenly decided not to OC very well

 

Any hints where newbies can find comprehensive info on mobile overclocking? A bunch of links would be very welcome. I did search for it, just am looking for info you found especially useful. Thanks!

 

Use Google to search through this forum. The in-built search feature is VERY dodgy for some reason, it never seems to be able to find anything.

 

I posted this on the link called comprehensive overclocking yesterday.

Hope it helps.

Lets go crappy alloy bring your 840QM into this contest lets go come on

My apologies however it was your post inspired me to try it and so I skipped PLL178 that was causing me to BSOD and it just kept going up. I will stick to PLL190 at the moment because im hitting near 70 watts at full load and with a 45nm my power brick might start swearing at me.

A worthy 1000th post!

 

My my my Dallers, what sexy BCLK speeds you have~!

Those are some nice values Dallers! Congratz!!!

Here's my max stable (ran prime95 and TS) w/o errors:

http://i.imgur.com/iHIBB.jpg

I insta-BSOD @ at about 187, and I like to drop 4-5 PLL to ensure stsability, which after running TS @ 1024 and Prime95 confirmed it.

I could have probably gone up to 183 or even 184 but im content at where Im at. It was already a decent jump from my previous max of 161 PLL.

ANYWAY, IM NOW OF TO FLASH MY BIOS TO 211 SO I CAN BEAT YOU DALLERS!!!!!!!!!!!!

just kidding, no more messing with it for me. Im content with my values.

Interesting update: When I had my power plan set to 'Power4Gear High Performance' I insta-BSOD at about 187PLL. But when I set it to 'Balanced' I was able to creep up to 190PLL crash-free (stopped there though), immediately ran TS bench, got an error within the first 30 seconds, dropped to 188PLL, error again after 2 or so mins, and now Im running it at 185 no errors so far....what....the....hell? Dont quote me but not only does OC potential have something to do with BIOS, but it also has something to do with power options? ohhh boyyyyyyyyyy

Update 2: TS Bench 1024m passed @ 185PLL, running Prime95 now...

 

@dallers did you do anything to get your turbo mode to work. Seems that when I put it into turbo and then back off, it lowers my PLL in setfsb.

IE just tried it before leaving for work. Before turbo I'm at 168, click on turbo and it drops me to 155, click it off and it goes to 144.

 

Haven't touched the turbo fella. When only running on 1 core my turbo reaches 3507mhz at 190PLL.

Still waiting to be contested then I will begin creeping higher!

 

OHHH, I C. How do u test just the 1 core?

Also what is the ratio to determine what the 1 core turbo is capable of reaching? (FSBx21=?)<--that it?

 

Hey dallers, have you even ran a stress test on your cpu yet? Preferrably prime95 and ts bench.

The reason why i ask is 1.you havent mentioned passing a stress test and 2.although i passed both tests at 185pll, i crept up to 188pll 2 hrs ago and just been browsing around and playing music no issues, but as soon as i run stress tests i get errors. My point being, though 187pll hasnt been acting up at all i still dont consider it my highest stable considering i get errors running tests. To me a true oc is where you dont get any errors. So yeah run some stress tests.

 

See the screenshot I have posted at the beginning of this forum post. See my gadgets and HWINFO32 is at full pelt, 2ghz over all 4 cores.

That is under stress and had been for 20 minutes at that point. Prime 95 is minimized you can see from my icons and no errors or glitches had occured unlike at 178PLL my gadgets would fail and then a lockup would occur shortly afterwards which is why I never bothered trying to go over 178PLL, I left it running overnight and it reached 79oC average temp but no errors occured. I tried stressing 192PLL just before I left for work and it hit 73watts and started throttling badly until the point that only 1 core was being stressed so I fear 190PLL is going to be my limit and I will probably drop it to 185PLL to make sure it remains stable when the GPU is draining power as well. Still happy it is possible.

To stress using one core I used Orthos which allows you to stress only threads 1+2 or core 0.

To find out what the turbo mode and ram can hit max I just run maxmemm test it displays this information at the top and its a really useful program.

 

So you say you fail at 178, but you can get to 190. Was this just trial and error or did you jump about 5pll each time?

Reason I ask is that if I put it on 161 and run Bench and Prime95 I get errors, 162 insta-BSOD, 170 fine with Bench but fail with Prime, 169 lockup, 168 seems fine. So I jumped from 159 to 170, expecting a lockup, but it was fine until prime. I've worked to 168 and it seems to be fine, but I might try to jump to 180 and see what happens.

 

It was mentioned in this post of a similiar issue about overclocking working differently under different settings BIOS etc, I realised I hadn't tried to go higher since I applied the W7 timing fix so decided I would see what happens and it just kept going up.

The hope of it continuing up past 190PLL is gone though clearly the voltage/brick cannot handle higher but one thing that may be a mitigating factor is that I do have a foreign brick and a UK convertor so this may be a factor in why I get so much juice, and probably why my electricity bill is so high

 

what is the standard outlet over there 220V?

 

240V I believe in the UK but I am no expert I overclock and repaste thats about it when it comes to power I just plug stuff in.

 

the power brick should handle both 120/220(40)V without a problem. Look on the sticker, it should say so. You can get a cable that goes from the outlet to the brick for around $10 if you want. It might make your life simpler.

 

I will have a shifty when I get home im at work at the moment.

Obviously not working however

 

Hi man, can you send me your clock generator ( G73GONEWILD) please ?!!

 

ditto. it helps when you are the boss

I wouldn't think you brick had anything to do with it. I would assume that chip is only allowed so many watts. I would think your ram speed has more of a factor in it.

 

Actually, unless i'm mistaken, the JH is capable of delivering around 175W of juice but the power brick is only rated at 150W. I never tested this but i think i came a cross a thread where this was mentioned. I could have been dreaming too but i bet Chastity knows.

Awaiting confirmation from the G73 goddess .

 

Still the voltage going to the CPU is going to be a big factor along with the RAM.

Any differences noted between the 211 im using and 213?

 

ahhh, I didn't know that. If that is true then that may be why.

 

Found where i came across it: http://forum.notebookreview.com/asu...xm-multiplier-tdp-tdc-values.html#post6663385.

 

Rgr that. I'm guessing Chastity is installing her new RAM. I'm looking forward to what she has to say about it. i'm still guessing that my 1066 is holding me back. I may pull a stick of ram out to see how that affects my OC ability when I get home today.

 

Well after more testing, 185pll is official my highest absolute stable OC. Dallers, you and I both have the same model, except you have 8gb ram and i have 6gb. Not sure what else I can do on my part other than try BIOS 211 and test there....but nah. Im content with my OC since it already surpassed my highest expectations.

Well, again congratz, on your 190. I highly doubt anybody else will surpass that and remain stable.

 

Kneel before me peasents! :laugh:

Only joking it was no competition I was just interested to see why I can overclock this high and will be dropping it down later to make it more stable. I am content with 1.9-1.95ghz which is still very high for a mobile CPU.

Will see what the benchmarks make of the 2ghz later and update my results played on The Witcher 2 earlier and noticed that my frames handled themselves a lot better only 1 or 2 frames higher but it did not drop as it did before should weather come along or the scenary change in quick concession. Of course ATI drivers and a hotfix is required but maybe a 720qm is struggling slightly in the processing department and the extra 400mhz should make a difference if it is.

 

I have my 740qm at 2 GHz.

 

LOL at Dallers excitement
i wonder if parking the cores would have any difference?

 

Well I know mine are unparked. I doubt I'll be able to get that high. Maybe I'll just get a 920 and then smile at him!

 

It does help. Thanks! I also found this guide.

 

Smile at me all you like I couldn't care less.

I did not post this to show off I wanted to see if others are able to produce similiar results or if there is a reason why I am able to clock to whats seem no extent until my CPU throttles itself, a bit of banter does not hurt. I have changed no settings and have been limited to 178PLL since I applied the timing fix but now can raise the PLL upto 196 and still I do not lock up although stressing causes massive software failure and error logs when I raise it that high.

I still do not believe my chip is a one off and there must be a reason for it.

Your welcome and my god I haven't seen that post before that is what you call a comprehensive guide to overclocking

 

Yeah, the reason being the combination of BIOS 211 and 8gb RAM duh!

i kid i kid

 

Damn Dallers that is a insane BCLK.

How many others in this thread are able to push higher BCLK's with the timing fix? I'm not getting any difference after applying the timing fix.

I max out at 162bclk all threads. Any higher BSOD. Load temps are 85c which is higher than I'd like.

I can run 164bclk stable if I only stress on core#2

 

Alright Dallers, seems my BIOs 213 is whats causing my higher-than-159-PLL instability, which means I cant hit 3.6ghz anymore only about 3.45 lol but I still have those 2mb extra cache on you and your 720 and with my new adapter I seem to be able to get 900/1150 on my GPU

 

Crappyalloy did you get that Targus adaptor? Did it really let you get that high with your GPU? What where you settings before?

I'm wondering if I'm running out of brick. I have my PLL to 168 but I can't get my GPU andy higher than 755/1055.

 

any chance to throttlestop / get fsb the sandybridge 2630qm in g73sw?

 

Tell Tell what adaptor is this? I need more juice that is clear and I care little for the cost of electricity

In regards to stability I lost it after repasting for some unknown reason. My temps are lower, I used IC7 but now I cannot get it stable past 187PLL?! .

 

I 'think' it is this one: | APA05US | by Targus

I remember seeing Chastity talking about it.

 

Yes I did. Well its made my OC's more stable, but it seems it didnt really extend my max OC (GPU wise) upon further testing. Before if I set it at or above 900 on the core it would instantly crash the drivers, then come back up, and crash again, etc. Now I can actually sit at those clocks and nothing happens. However it still wont hold in-game. *shrugs* 870/1150 doesnt burn the PSU up like normally does though. Some chips are just made differently (luck) then others. It might help, it might not, cant be too sure, sorry.

EDIT: Oh I might have misunderstood what you were asking. My "original" max GPU OC was already 870/1150.

The 180watt Targus PSU/Adapter Chastity likes to spam lol
Only gets warm to the touch, even when OC'ing for long periods of time, as opposed to the stock one that would become burning hot after a while (and after my dog knocked that one around, started shutting down my G73 once it got too hot, and even just warm at times). It may provide just enough breathing room for what you need, as I told cuban, cannot be too sure.
EDIT: Yeap the one cuban linked, though I got mine for about 50 bucks (you're in the UK right? not sure about over there) all said and done.

You may have just about caught me in the CPU department but im telling you im going to find a way to get to 900/1150 gaming-stable, possibly 900/1200 and hold that crown lol

 

does it mean, if we have bigger ac adapter, we have bigger OC potential for GPU ?

 

No read what he says above just makes it more stable however better Adaptor - more Watts - more power.

The Asus standard adaptor is not made for overclocking so it struggles to produce the juice.

 

That's usually not true since the power draw gets limited by the motherboard. Keep in mind that the components on the mobo are only rated for a certain max current/voltage, you can't simply push more power through it without the risk of killing the board. That's why it's usually limited... higher rated PSUs may work, but in most cases won't let you draw more power.

The PSU of my M15x can deliver up to about 180W during benchmark runs with highly overclocked components, and users with the 240W adapter reported the same values.

An advantage that a higher rated PSU has, is that it runs less hot during heavy load. Would be interesting to see the power draw of an OCed G73, I'll do some measuring with a kill-o-watt and a JW when I find time.

 

So in my case it is true because I have a 160watt adaptor and the Targus is 185watts and as you state the PSU of your laptop can deliver upto 180watts if this is similiar to the G73 then I am losing out on 20 watts of juice.

 

Well, my PSU is actually a 150W PSU, but it delivers up to 180W (say ± 10W measuring error). What I want to say with this, is that a high-quality PSU can deliver more than what it's rated for (but it gets pretty warm). I assume you can get to similar levels with your standard PSU.

My point is that you can't expect that your system can use 240W just because there's a 240W PSU plugged in. 180W max power draw for a system with a 150W standard PSU seems reasonable.

 

svl7: Keep in mind that your power adapter is probably rated to deliver 150W DC. It will show this on the label. Most users measure power consumption at the wall with something like a Kill-a-Watt meter which is showing power consumption in AC. As you approach the maximum that a power adapter can deliver, more of the AC watts coming out of the wall are being turned into heat so even when you're sucking 180W from the wall, your adapter still might only be outputting its rated 150W DC because of these efficiency losses. I believe that the Dell bios has to support a higher rated power supply for it to work correctly. If it doesn't, the extra watts will be ignored. I'm not sure how Asus boards handle extra wattage but I don't think they have the same built in bios limits that Dell uses.

 

@unclewebb: That's true, I'll see whether I can make a more precise measurement to see what the PSU actually delivers under very heavy load and OCed components, would be interesting. But could be difficult... I'd either have to cut some cables or strip down the whole system, haha.

 

Is there something you could plug the adapter that allows you to control the power draw and measure it at the tip instead of at the electrical outlet. Using that in conjunction with a kill-a-watt meter could allow you to get a figure of how much the adapter delivers compared to the reading on the kill-a-watt meter.

I'll ask the technicians at university about it tomorrow if i don't forget.
