SetFSB OC'ing G73JW CPU

Hey all!

I was wondering if you all had any luck OC'ing the i7 740QM on the G73JW on setFSB...I tried to go to 170 but I got a BSOD--maybe a taaaad too much o.o.

Screenshots are welcome, and thank you for the support!

 

Bumpity bump

 

My 720QM goes to 160. Absolutely not 1mhz over, but completely stable at 160. I think it's a motherboard limitation, because it simply hard locks about 2 seconds after I exceed 160, before any stress testing. Seems unlikely that the CPU would have such a hard wall.

Wondering if maybe it's a bootstrap issue......

 

It's a Core i7 issue AFAIK. Unless you use unlocked or extreme Core iX processors you can't really overclock them. They don't work like previous generation processors. They don't have a FSB, and they adjust performance based on many parameters to stay within thermal design limits.

 

Is it possible to overclock the G53JW? It seems to have the same hardware as the G73JW.

 

Actually, that statement is somewhat misleading. The i7 architecture uses an external frequency as a reference for its timing. The frequency generator is the PLL. If you wish to think of overclocking i7 processors in terms of overclocking older Intel processors, when you overclock the PLL, it is almost the exact same as when you used to overclock the FSB.

The PLL determines the CPU speed, QPI speed, and memory speed. (probably a few others, but those are the big ones off the top of my head) It is the PLL that setFSB overclocks. The RESULT of the PLL overclock is that the CPU, QPI and memory frequencies go up.

I wasn't wondering at why my 720qm wouldn't overclock at ALL... I was wondering why it quit at 1.92ghz! My PLL doesn't seem to wish to go above 160mhz (133 default). It runs right up to 160, passes stress testing, but at 161mhz, it won't stay on long enough for me to even START the stress test. In my desktop experience, when you are approaching a CPU barrier, you start to lose stability slowly. One MHZ difference results in a small difference in stability, not a complete loss.

Is there possibly a custom BIOS that allows better overclocking options? This machine just seems to need one bug worked out and who knows how high the 720 could go!

 

I wish! My little HP MINI is OC'd at 2.34 from 1.6.

 

i can go up 2 175 untill it freeze..but i normally oc to 170..



and its stable to play games or benchmark using the 170..

yes it possible.

 

That's just the slider setting... The PLL is set at 153.3 in your picture there.... As I recall, my slider setting goes to 180, with the PLL at 160.0. 181 is insta-crash while 180 is benchmark/stress stable. I think it's 180, but I can't recall for 100% certain. My screen is out at the moment, as I got the Best Buy model and am in the process of replacing the screen with something a little more suitable to the platform!

 

Hey -keph-, this thread is talking about the JW model, not JH.

 

JW and JH use the same PLL, same CPU choices and same overclocking method. It is likely the case that overclocking results will be more or less identical between the two, and valid for general comparison. A 3dMark score will obviously differ, but is still valuable information that, in my opinion, should be celebrated!

 

dont u think i can read ENGLISH ??? im just comparing i720 n i740 here with the same program we are using to oc...

@xfinrodx sorry mate i thought ur talking about the slider there..hehhhahaha...well i guess its locked..so a max up to 160( u can see my cpu-z validator down at my siggy its 158mhz when the slider is 170 thats y when i try to go to 175 which i assume is 160mhz ++ it freeze)

@xfinrodx dude can u try to run vantage and see what score u get??im just trying to compare i740 gtx460 and i720 5870m scores...thx

 

No problem, keph! I would love to know if anyone has exceeded 160mhz PLL and if they did anything crazy to get it over...

 

hahahah thx..welcome to notebook review forum...my higest vantage score is 9300-9400 oc'ed..and 3dmark06 13000-14000 oc'ed..

 

I'll run vantage probably THURSDAY (grrrr....). I got a 1920x1080 screen shipped to me, it arrived yesterday. I tore apart the screen, opened up the box for my new screen... aaand was greeted with this:



Brand new lovely screen, totally fudged by UPS. The company was cool about it and are shipping me a replacement. I paid a $5 charge to have them ship me the new one before the UPS resolution 7-10 days from now, and the new screen should be here thursday- in a double walled hard cardboard box.

But yeah, back on subject, I'll run you a Vantage when I reassemble the laptop. I thought I was around 9600 last time I ran it, but I will definitely be pushing everywhere I can for a nice tidy 10k soon!

 

wow whats that did they break it??damm..looks pretty beaten up...btw u can reach up 2 9600 wow thats nice..i thought 460 cards on a stock jw reached at around 7500ish..(thats the review on notebookcheck.ne*)which i also see a jh stock will reach 8100 stock thats a 600 point differences on STOCK..

 

No need to be aggressive. I'm still new to G73/G53 lappys.

 

not sure setFSB is a great idea for overclocking. Ive been running into some problems with various games like counterstrike source in multiplayer which basicly records your clockspeed wrong cause everything to be jerky and your player model to move like a 'speedhack'.

Is anyone else having this issue with setFSB and counter strike source? it's a shame I cant overclock the cpu on this thing because it would give the fps boost I need to run source at 120 consistantly for compeditive reasons.

Seems to only affect certain multiplayer games and its highly annoying considering the fact the temps for the cpu are so low they could do with a boost as its bottlenecking the GPU.

 

For my part, you're alone with that issue... My setFSB overclocking works fantastic. My startup shortcut auto-applies my overclock and it simply works fast! Haven't noticed any stuttering. I do keep my system clean, though. I have never used ASUS's Windows install... My first boot up was with Windows 7 Pro install media to wipe the factory installed virus. Probably helped me sidestep a few issues, perhaps this is one!

Are you sure you have the program configured right?

 

yeah I set the clock generator to g73jh and then move it up from 139 which is default.

the overclock works and it shows in cpuz id but however it appears to have a problem in source engine 'multiplayer' games. Its almost like the server is reading your clock speed wrong so it becomes out of sync.

hard to explain but for normal windows desktop use the overclock works fine. do you have counter strike source or a source engine game like tf2? give it a try and see if its not jerky etc when you do the overclock. Since its mainly what I play I decided to set it back to defaults and then the problem came right on the multiplayer servers with no jerkyness and it was fine when I hosted a singleplayer game with bots :/ weird

I also did a clean reinstall with windows 7 pro minus the bloatware and to my knowledge my system was never infected with a virus

 

I have played left 4 dead 2 fairly extensively on this laptop, both as a client and a client/server. Nothing jittery at all, no jerking around. I think something else might be going on with your machine... Danged if I know what, but setFsb overclocking is certainly not blanketly problematic with a g73. Hopefully you figure out what the issue is and can share it with the rest of us!
