G50Vt-X1..Should I be a bit worried?

I have an well...you know already.
I am running Windows 7 Ultimate and the stock win 7 drivers for it...And now I am getting funny results...but I probably should not complain...you see my stock G50's p8400 has magicly gained an 9.0 Multiplier...making the over clocked mode from direct console= 2.63 GHz...I was under the impression that this was impossible...
CPU-Z results:

what a pleasant surprise! but how is the temperature?

 

Well..here is the problem,you see the Cpu-z only reports that at idle and not load...IDK,maybe it is an glitch...

 

9.0 is only on one core. It's through Intel's overclock-a-core thing. If there's a core being used more than the other, the cpu will overclock it slightly. For example, when I overclock to 2.7 GHz, I have my LCD set up to read the cpu's actual clock and it usually reports 2.718GHz. Every so often it will peak to over 2.8 GHz, and I've even seen it hit 3.0 GHz very briefly on multiple occasions. This isn't a sustained overclock, just a single-core single-threaded boost straight from Intel. If you try making 9.0 permanent in something like Crystal CPUID the computer will bluescreen. In my experience, anyway.

 

It's called Intel Dynamic Acceleration (IDA). CPU-Z isn't the most accurate tool for reporting this. When IDA is enabled, the multiplier will be constantly bouncing back and forth between 8.5 and 9.0 depending on load and how many cores are in the active state. This is happening hundreds of times a second so sampling the multiplier once per second only tells you part of the story.

If you want to see what's really going on try using ThrottleStop

It can accurately monitor the average multiplier on each core using high performance timers built into Core 2 CPUs. Post a screen shot of ThrottleStop while half way through a Super Pi mod test.

 

+1 for unclewebb.

 

Tis true...BTW...How long can I expect to wait to see an BSOD if I tried to change the multiplier via throttle stop?

 

Pretty instantly as soon as you check that box next to 9.0.

 

Before playing with the multiplier, always adjust the voltage to its maximum, then put a check mark in the Voltage ID box, then you can try changing your multiplier and putting a check mark in the Set Multiplier box. If you don't, a BSOD may be in your future. Some laptops are more sensitive than others when it comes to this.

Your P8400 is showing that Intel Dynamic Acceleration is working just fine.

An average multiplier of 8.84 on the hardest working core is exactly what you would expect to see when the multiplier is bouncing back and forth between 8.5 and 9.0. Any background activity immediately will drop the multi down to 8.5 as it wakes up the second core. When the background activity has been processed, it goes back to sleep and the one active core can use the 9.0 multiplier again. This switching back and forth is happening constantly. You can't have the 9.0 multiplier locked on when both cores are in the active state.

At least ThrottleStop is able to show you your multiplier accurately when this is happening.

dtd00d: Can you test that again by adjusting the voltage first?

If you want ThrottleStop to report your core temperature just add this to the ThrottleStop.ini configuration file:

TJMax=105

 

So am I able to do any over clocking with the utility,I see that the Bus speed box is grayed out,I mean I know I can change the multiplier of the Phenom II 955 in my Desktop project butt...
Has anyone ever been able to override the Multiplier lock on an C2d?
As I know it the upper models are just my p8400 with an extra multiplier.

 

The purpose of this tool was to monitor for Clock Modulation which is a technique being used on Dell and Acer laptops to slow them down to a crawl. ThrottleStop can help reverse that problem on many laptops. It can't be used for any FSB overclocking.

Let me know if adjusting the voltage first works for you. I plan to add that safety feature into the next release to minimize the chance of a BSOD.

The multiplier is locked on Core 2 Duos and there is no way to unlock it.

The 9.0X multiplier that you were seeing is simply IDA which all P8400 CPUs have as long as C3/C6 is enabled and the motherboard supports it.

 

So you mean to say that it is possible to up the mutiplier,And it works?!

 

The multipliers are locked by Intel. There is IDA available but that's it.

 

Sorry to be mister Question-O-Matic but Is this Clock modulation being used on mine,and if it is How do I use your tool?

 

On the Asus G51 with a Core i7 it was being used. It's a fairly new tool to allow users to find out if their laptops are being slowed down by this.

A lot of Dell laptops have this issue including gaming laptops like the Alienware M15x. Every laptop should be checked.

When none of the first 4 boxes are checked, ThrottleStop is in monitoring mode. I would click on the Log File option and then click on the More Data option. Go do some gaming for a while and then have a look at the log file. The two clock modulation columns should both show 100.0% for all entries. If it doesn't then you might have this problem too.

You can also test with Prime95 and then the ultimate test is Prime95 + Furmark. If that combo can't make your computer throttle then nothing will.

Some Dells are also using multiplier throttling where on a computer like yours with a P8400, first it drops the multi down to 6.0 at full load and then it switches on SLFM or Super Low Frequency Mode which internally drops the bus speed in half which is the equivalent of dropping the multiplier in half. That shows up as a multi of 3.0 in the monitoring panel when that happens. I haven't seen any of the Asus laptops do anything this insane. After that, Dell throws on some clock modulation to really slow things down. It sounds like a bad dream but it's true.

 

Hm. Both cores are reporting >8.5x multipliers when you have the box checked? That's pretty cool. I still think you can push a P8400 past 2.63 @ 8.5x if you really wanted. Mine runs at 2.72 (2.80 w/IDA) comfortably.

 

Random BSOD starts at 2.88MHz..Personal experience...

 

Haha, mine runs almost 1000x faster stable

I assume you mean GHz, in which case I concede defeat. 2.79 was my limit

 

Oh..Yeah...Thats meant to be GHz...
BTW...I was running Crisis Warhead set to enthusiast(It is awesome!) yesterday and without an cooler my GPU temp reached around 98C....The fan was full throttle and there were no obstructions to the vents...Once again...Should I be worried.

 

110C is the critical threshold when the card will downclock itself. Since you're not at that level, I wouldn't say it's an emergency but just under 100C isn't exactly cool, either. At 98C I'd definitely start taking precautions like propping up the back or finding a nice cooler. I've read somewhere that it's not really the high temps that will cause the board to just suddenly die (although it isn't as good for it), it's the quick fluctuation between high and low temps that expand and compress the joints ever so slightly.

In any case, the cooler the better. Other people will tell you you MUST find a cooler if your card even thinks about a temperature greater than 80C or else it will DIE. Whatever, I've been gaming >85C ever since I got this machine. It's working great, but to each their own.

I made my own cooler from a giant 12V fan used to cool a dozen giant capacitors on a giant microturbine board, and a mesh paper tray from Staples that I ripped a side off of. Works great! And just yesterday actually I drilled maybe two dozen small holes in the back plate over the fan and saw my maxtemps drop by 5-15C... I need to do more testing since I think the room temp changed. But that helped a lot.
