First OC experience on my G73JH

well today i decided to donate for SETFSB and check what can be done with it on the i7 720 QM, here are the results i got so far.

CPU-Z Validator 3.1

what do you think? i tested with Prime 95 and got max temps of 89oC on CPU(10 minutes torture test Run).

can you give me some advices to get a better result???

 

Not too shabby. I see you have 1333 ram. That seems to be the only thing holding mine back. I have the 1066.

 

how much do you get with 1066?

 

Isnt the stock speed for the 720 2.8ghz?

 

Your temps are quite high for a 720QM mine never went above 78oC even when I had it running at 190PLL/166FSB.

You might want to think about blowing out the fans with compressed air or consider a repaste to achieve better overclocking results. TwinTurbo is 143Fsb so you are only 5mhz above that.

Make sure you have applied the SetFsb Timing fix or you will not see any benefit from your overclock. See the movie in my sig for a walkthrough.

Yeah he has taken the screenshot at the 19x multiplier hence the lower clocks should be around 3Ghz under 1 core.

 

Dang, I was just about to come back and edit my post Dallers; I am multitasking a bit right now and I didnt notice that but agreed about the temps, mine has never gone above 76C (OC and stress testing), gaming is usually 60's, idle is 40's. Just for reference sake.

 

yes, when turbo boost uses just 1 core, I think i got this runing 4 cores, because when I checked the HWinfo 64 all 4 cores where working at that speed.

or may be I'm wrong and i just paid for nothing je je je, becuase when i go above 163 PLL on SET FSB sistem Freezes.

could somebody point a light on this? i afraid im may not be doing things properly.

 

Was gonna say there is no way in hell that Alloy didn't know this but thought I would take this chance and opportunity to get one over on you.

+1 to Dallers baby! hahahaha!

@OP Validate when your core hits x21 to show your max clock speed on 1 core.

As above ^^ read my post your temps are too high and have you applied the SetFSB timing fix?!

You cannot have 4 cores running at that speed with a 720QM only the XM models can run that speed over all 4 cores.

The 720QM clocks down at stock depending how many cores are engaged. 1 core: 2.8ghz 2 cores: 2.4ghz 3 or 4 cores: 1.6ghz

By overclocking the FSB you raise the overall core speed meaning at a guess you will have something like 1 core: 3ghz 2 cores: 2.6ghz 3 or 4 cores: 1.8ghz etc..

 

ok, i will try the "fix for SetFSB" thing, but as i stated earlier, i'm not able to turn PLL above 163, when I hit 164 side bar closes if I go for 165 I get a BSOD.

Dallers how were you able to get PLL to 190 with out freeze?

how can i get just 1 core running? cause i watched for 20 mins and never gone above 2.8 with x19

 

Dallers: bahahah hey! I am at a LAN party at the moment, with all of the games and conversations going on, I shouldnt have even posted to be honest lol

psycho.wizard: As to which PLL any one person is stable up to is mostly luck, I for example have only been able to hit a max of 168, with 165 being the most stable at the top. To see how high it will go single core, run a stress testing tool on one thread (or one core if thats an option). Something like wprime or CINEbench should work. You can also calculate the theoretical max by (in your case with the 720) multiplying the BCLK by 21.

 

so i pretty much spent money for almost nothing because if with TT FSB goes to 143 (153 PLL) an I can only get + 4-5 Mhz on FSB (160 PLL "Stable") that means that it would have been better to stick only with TT instead of purchasing the SetFSB wich makes my system unstable with those extra 4-5 Mhz, i just had a freeze lock with out OC, i thing that "SET FSB Fix" mesed up with My W7.

 

The "fix" just syncs the performance timer with a consistent "tick", it shouldn't result in any freezes if done correctly; however, you may have a few random lock ups and reboots if you have just under gone several failed OC attempts with setFSB, it happens, after a couple of restarts it should stop (you are messing with the base clock of the entire system after all)

IMO its not a waste, for me TT still removes a multiplier. If I use setFSB, and set it to the same PLL as TT does, and run multiple CPU tests, my multipliers are always one lower during the TT tests, especially when in quad core mode.

Which BIOs version are you on btw?

 

running Bios 213 and Chastity's VBios, the thing is that hang up ocurred again, just left the damn thing and went downstairs for dinner and when i came back, screen was off, keyboard was off, all the other lights were on, but system just was not responding, i presed every key on the keyboard, and touchpad, even usb mouse, but computer does not respond when this happens, only way to fix it is a hard shutdown and restart, and this is happening with out the overclock, already done registry cleaning and defrag, but issue still persist, and started when i started using "the fix" any idean on this?

also i know that G73JH can handle the i7 920XM procesor because dallers has one of those, but what about the i7 940XM?
i saw the intel website and the 940 has more power that the 920, but if i change to that ES procesor, can the MoBo of the G73JH handle it?

both chips are 55W max, but will the 940 produce more heat? can the colling of the G73 keep with it?

wich one do you recomend? 920 or 940?

 

It can handle both the G73JH has a TDP of 55watt.

The only reason most go for the 920xm is the price vs performance because it is unlocked you can just raise the multipliers with Throttlestop to above that of the 940xm and save yourself a couple of hundred $ although overall the 940xm is better.

Also the ES/QS versions of the 920xm are going very cheap on ebay. Mine cost £200 a while ago.

Re the 720qm is trial and error really shifting the RAM around, different amounts of RAM and repasting to lower CPU temps all yielded different results for me its a game of luck really but your temps being 89oC are hit I would recommended repasting..

 

I'm able to get to 165 PLL (if I remember correctly).

One thing I found was by switching from 211 to 213 I lost my ability to OC a few PLL. Once I reverted back to 211 and then updated to 213 I was able to get higher than previously, but still not as high as I could before. Pretty random if you ask me.

 

1. Why fumble around with this tool - and get a few Mhz more?

2. Is it "the excitement value" you get? Because in games it´s useless IMO!

3. The heat, the d... heat! Unless you turn on the fans with RW-Everything, you´ll burn the CPU...

Here´s a suggestion:

Turn off ½ the CPU cores with "Processor Affinity" and turn on Twin Turbo, that will give you more performance, at least that´s my experience with FlightSim X, but you kids probably don´t play this year 2000-coded Hog!

 

1: I managed to get mine upto 190PLL which boosts the speed from 1.6ghz to 2.0ghz over all 4 cores and from 2.8ghz to 3.4ghz when running 1 core and in CPU terms that is the difference from upgrading the CPU or not.

2. Games it is not useless test it yourself 4 cores running at 2ghz against 1.6ghz in Civ 5 / Starcraft 2 CPU intensive games it will make a difference. With my 920xm running at 3.2ghz*4 it makes a substantial difference.

3. The heat from overclocking my 720qm was minor only 6oC idle and Prime 95 overnight reached 78oC maximum without additional cooling.

OP just needs to either repaste or clear out the dust in his fans for his temps to drop.

 

already cleaned the vents, temps are the same, i think that I'll have to wait for my ICD 24 to arrive from canada, but the postal service here in mexico sux, i think they are going to lose my paste, but a canadian ebay seller was the only one that wanted to ship to mexico.

 

A few bucks for a bit more power is not really a waste of money and SetFsb is for life as well.

If you dont see the results the 920xm is your way forward. See my sig for results it packs one hell of a punch.

 

yea, i already contacted a seller on ebay that exanges 720s and 740s for 920s and 940s, just waiting on the response, i think it's called monkey something ja ja ja.

if the price for updating is less than 200 dollars, I'll go for it and forget about the new car stereo i wanted je je je.


Edit: it's time for going to the university, read you later.

 

Laptop monkey are who I got mine from also I was very impressed with the seller my chip runs perfectly and it arrived next day.

 

Thanks Dallers, maybe I should consider this "E-Bay Monkey, something..." - and get me a 920 or 940, Flighsim X is totally CPU bound...

Anyone want´s a cheap 720?



Edit: Found the "Laptop Monkey" - is this the right CPU, overclockable?

@psycho.wizard: You mention "a seller on ebay that exanges 720s and 740s for 920s and 940s"

What do you mean, does he take your 720 in exchange or what?

Sorry, I´m not English native...!

 

yup thats the seller, what i mean with exchange is that on the i940XM ebay item, he states that can take you i7 in exange plus an X amount of money i sent him an email but I have'nt had a response yet.

I found Laptop Monkey very helpful and the item was in pristine condition and super fast delivery. For a QS/ES model that is no different to a Retail/Oem in performance and output. Highly recommend them personally. Make them an offer though they normally knock off $20 even more if you bypass Ebay and pay them through paypal.

You dont use Setfsb to overclock the 920xm you use Throttlestop. Unlike the QM models the multipliers are unlocked so instead raising the BCLK speed you are just raising the multiplier ratio.

For instance 720QM (Locked) running:

1 Core 21x: 2.8ghz 2 Cores 18x: 2.4ghz 3 or 4 Cores 13x: 1.6ghz

You can choose what multiplier you want the CPU running at:

My 920XM (unlocked) is currently:

1 Core 28x: 3.6ghz 2 Cores 26x: 3.4ghz 3 or 4 Cores 24x: 3.2ghz

Depending on the load it will raise your temps and will require a high wattage to power these overclocks I am currently running at 95 watts when I use Twin Turbo to reach 4ghz on the first core This hits 90oC with ease though. Generally I run at around 90/75 without throttling. My overclocks above can comfortably handle 3.2ghz *4 core Prime 95 with a max temperature of 88oC. The power output is outstanding desktop power in a laptop. Additional cooling helps obviously I have an SF-19 Storm with a small Air Con feeding it cold air and the maintenance panel removed

In regards to performance do not listen to the '' it has no performance gain in gaming '' because it is not true. Yes you may not see a huge increase in GPU intensive games but what you will see is more stable frames in games that drop rapidly the biggest improvement for me was Dragon Age 2 and Witcher 2 because they are games that run between 30-40fps with the highest settings so you do not want it dropping below 30 and the XM processes so much faster. See my thread for a link to the difference in FPS in games you will notice the minimum frame rate raises significantly. Along with processing and editing becoming super fast, installing a major speed increase and in general things run smoother. CPU intensive games see a big increase in terms of performance.

If you are not aware of what the XM's do/work/perform you might want to read the God's of Xtreme models discussion in my thread. They helped me understand fully the XM and how it works and how to safely reach my stable overclock using Throttlestop.

 

Awesome!

Thanks for the info guys...

This is a cheap way to upgrade, because the AMD/Radeon 5870, and 6 Gb 1333 RAM etc. works OK, just too many stutters and eventual decreased IQ in Flightsim X, which is the only thing I play!

Just got an i5 2500K @ 4.8 Ghz on my regular rig, so the G73 suddenly appeared very slow...
