Extreme Overclocking of my Sager NP 5720

Thread Starter 
I just OCed my Clevo M570A (better known as Sager NP 5720 here) to see how far it will go.

In the BIOS I can OC the CPU up to 15 %, in this case to 2,44 Ghz.
The graphics will go up to 473/1320 Mhz.

So lets the the results (with 81.94 modded drivers):



Not on the screenshot but also nice:
17715 points in 3DMark 03 and 31,75 seconds in SuperPi 1M.

Can anyone beat this?

I think I have noted elsewhere, the comparison of the XPS2 to the 5720, must allow for what the 5720 can do (as we see here). A 2.4 P-M is a VERY good cpu, for both gaming and office stuff.

Nice job

Have a look in the BIOS under "Advanced Chipset Features" .

Mine is from Cyber System in Germany.
It seems to be that there are different versions of this notebook. Mine is one of the neweste ones.

8078 for 3D Mark 2005 is insane! That's 1000 pts higher than anyone in this forum with a Nvidia Geforce 7800 GTX Go! Your non-OC score must have been in the region of 7200++ right? Anyway, congrats on the system, it's crazy.

KUDOS on the scores, however we must be very careful here folks. Remember that while the score looks nice, OCing your systems too much can have terrible long term affects on your hardware. NEVER OC without proportional cooling. This is to say that you can damage your system without even knowing it. The effects can onset gradually, so unless you're a pro, don't even think about it.

Be VERY careful with OCing people, its not worth frying a $2800 laptop for a few more 3DMARKS...

Just my 2 centavos...

Can you post a link to the 81.94 "Modded" drivers used to obtain this score? I would like to do a baseline and see what I score without OCing. We have virtually the same config...

Thanks in advance...

Here are my results:
System: CyberSystem X-17 aka Clevo M570A aka Sager 5720
CPU: Pentium M 745, Pinmodded @ 2.4 GHZ
GPU: 7800 GTX, Biosmodded @ 475 Core 1300 Ram
Driver: orig 81.94

EDIT: damn, the pictures are sooo small... here the result : 8037 3DMark05




Temperaturs: Idle ~30°C, Load ~ 51°C

I love my X-17

HOLY CRAP!!!

I honestly don't know anyone with a desktop that can beat that!

One buddy of mine has desktop with AMD 3200+ / 1gig PC3200 CAS 2.0 XMS / and 7800GT OCed a bit.
His score for 3dMark2k5 was 7734

He has an SLI board so I suppose if he added another 7800GT he could beat it. But Still!!!!

D@MN THAT'S FAST!!!

Hi, where are you guys getting your modded drivers from? I have a friend who's just bought a 5720 and every time he tries to overclock using mobile ForceWare 81.94 and the Coolbits 2 mod, it automatically resets back to the default clock speeds.

Can someone please post a link - quite a few people on NotebookForums and NotebookReview have asked about this.

Also my friend’s 5720 doesn't appear to have any CPU overclocking features in the BIOS - what BIOS version are you guys running?

First off - overclocking should be done carefully but it's not detrimental @ about 10-15%. I've run several cpu's for literally years a bit more than that and they have been just fine.

Second, if the 5720 can OC, it's gonna make the Dell look like last week's leftovers to enthusiasts... You'd think Dell would respond with at least a cpu oc based on Intel's "burn in mode" sort of a 10% thing, at least on the enthusiast model. Yes I do realize that mode isn't in portables, but if you look at the 5720 you have to wonder

Anyway kudos to Sager!!

can you guys post links to your "pin mods" never heard of one hitting 2.4, but that's amazing

and on a laptop...makes me rethink on whether to go w/ the 9750 or the 5270

Did you have it sitting in your freezer when you got those numbers?

Nice....

thx for the gratz!

first off...
i didn't oc the fsb, it is still 133, look at the cpuz-picture!

you dont need any modded gpu-driver. the only way i know how to oc the gpu is the old fashioned bios-mod. it work the same way as it do for my old xps gen2.
you need nibitor to manipulate the original-bios and nvflash to reprogram your gpu-bios. all these tools can be found free, just google for them.

the cpu is easy and quick modded with the "wire-trick". just buy you a cheap fsb 100 pentium m cpu and connect two pins. if do it right you have a fsb 133 cpu with the higher possible multis. in my case i bought a pentium m 745 for ~250,-€ multiplier is 18, fsb = 133 -> cpu-speed = 2394 MHz!
i tried to oc the fsb via the bios but the system isn't stable.
i can even undervolt the cpu:


i don't need any extra cooling. cpu-temps are fine : ~31°C idle and ~55°C under heavy load. i didn't have any tool to read the gpu-temps!

happy oc'ing!

I would have to concur with you, however, I think folks could benefit from the following:

The following are my opinion's only and the information I present is not scientificly definitive. Like all things, almost nothing is (Except for GOD if you're a believer, which I am, death and taxes;-) I do not encourage overclocking, in fact I greatly discourage it. Those who OC, do so at your own risk, I will not be held responsible.

What exactly is the danger of OCing a CPU/GPU?

The specific danger is heat. When you increase the clock frequency of a microprocessor, you place additional stress on CPU/GPU transistors as their workload increases per clock cycle. This additional stress causes transistors to heat up more quickly. If you cannot properly cool off these transistors and cool them off quickly, you risk permanent damage to these transistors thereby potentially "Frying" your chip(s). This can result in a complete malfunction of the chip(s) or intermittent anomalous issues, such as, lock ups, graphical artifacts, random shut down's, etc.

Every chip has its own tolerance and volatility, if you're going to OC, make sure you research the chip's reputation for OCing and build your own baseline thresholds (Collect as much info as you can and try and identify a trend if possible). Collect this data from professionals and not just anyone you read an article from on the internet or a post from a forum.

Why should I overvolt my chip?

The reason for this is stability. The more energy exerted, the more energy required. Of course this all adds up to more heat, which requires you to provide more cooling. Overvolting a CPU/GPU is crucial when OCing, this is because as you increase your transistor duty cycle, you will eventually exceed your processor's tolerance whereby the processor can no longer function properly because it simply does not have enough energy to maintain its workload. You must proportionally increase your processor's voltage to its duty cycle. This is like running around your neighborhood block over and over again. With each lap you begin to run faster, eventually you exceed your bodies capacity to perform at the required workload, you run out of energy. Now a runner has a conditioned body, the runner can keep going where you faltered. This is because the runner's heart and lungs are proportionate and sufficient to the load required where your heart and lungs were not. Of course no matter what shape your in, you will eventually exceed your bodies energy threshold and colapse. The same with a processor, you can eventually reach a point where no amount of power can sustain the energy required from your processor and it will die. Just like the human heart, the microprocessor has a tolerance. If you can't get enough oxygen to your heart, it begins to die unless you can quickly resume a balanced blood/oxygen ratio. The same is true for the processor, if only hearts were as cheap and easy to come by ;-).

DOES A 10-15% OC = A 10 -15% INCREASE IN TEMPERATURE?

Absolutely not, processor thermal dynamics are relative to the given processor's thermal design characteristics. What is hot for one chip is cool for another, default operational temps are relative. However this is not true with regard to heat produced from OCing. Heat can rise exponentially when OCing based on the processors thermal characteristics, depending on materials and depending on the tolerance to heat those materials possess, a chip could be damaged with as little as a 10-15% increase in clock duty cycle without proper cooling. Some chips have a higher tolerance for OCing than others, plain and simple. Generally a 10-15% OC will not generate a terrific amount of heat from default frequencies. This is especially true with regard to those who have proportional cooling.

Just remember that the heat you are generating from from a 10-15% increase in clock frequency IS NOT proportional to your 10-15% OC. Depending on processor design, risk to benefit can be unfavorably proportionate and you can damage your chip.

IT IS MUCH SAFER TO OC A DESKTOP THEN A LAPTOP FOLKS.

Accessability to the friendly confines of a desktop PC's case to provide proportional cooling solutions is a major benefit to owning a desktop PC. While the 8000+ 3DMARKS are wonderful, just be careful as no matter how much you know or think you know, you can damage your system quicker then you think from OCing. It's dangerous enough on desktops, let alone laptops with microscopic confines.

I have been doing this stuff a long time, it's fun and addictive, just be cautious, logical, and conservative with your approach to OCing if you're going to do it...

Good Luck and God Bless

Happy holidays to all...
