G1S overclocking?

I haven't heard much on the overclocking potential on the Santa Rosa platform, nor on the nVidia 8 series. Not being a computer engineer I don't know how to analyze the system (though being around it long enough I understand it when it is explained to me). Has anyone here heard anything or have any ideas about the new platform? Specifically in the G1S, if I get one I am going to want to overclock it (not permanently, just for fun once in a while), what are the prospects?

 

Well, it seems that 8600GT has a good overclocking potential.
It mostly depends on the cooling of the laptop which seems to be good.
It's very very unlikely that the CPU might be overclockable.

 

I have heard a lot of that same thing actually, thanks muj!

 

The only CPU that is overclockable is a Core 2 Duo T7600G and it only comes with the XPS M1710 to my knowledge.

The desktop version of the 8600GT is quite an overclocking GPU. But as usual with notebooks, you usually can only overclock the GPU ~20% max. Unless it's factory underclocked.

 

I think Clevo M570U also is available with T7600G.Anyways, I don't think it's worth the money.

 

I really hope that the Santa Rosa Platform would function along the same lines like the Sonoma. The newgen Core2Duo processors are going to be a different Socket, it could definately be possible that a pin-mod or something along those lines would work but it really depends on the architecture of the motherboard and socket and if there will be lower grade processors made of lower clock speed and FSB. Santa Rosa would raise the current FSB from 166 to 200. 33Mhz per multiplier isn't a difficult overclock, it's just figuring out if it's possible...

I guess we'll have to wait and see...

 

You can overclock with Your own CPU if you can buy an ES version . IT's the best CPU for overclock because it's an unlock version of the CPU in testing.

Well, this only applies if you build ur own laptop with a barebone.

 

I really doubt ES Versions (Engineering Samples) would work in this situation simply because laptops don't function the same way as desktop motherboards where you can change the multiplier and FSB. ES CPU are mainly multiplier unlocked processors, I've personally never heard of mobile ES processors.

Even with barebone laptops, CPUs are detected and ran at stock speed thanks to the BIOS. I would forsee even if there was a mobile ES version, and even if it were to detect properly in the BIOS, it wouldn't run correctly since SpeedStep technology is based on the multiplier itself. I would imagine that the processor may just run at the lowest or highest multiplier available on that laptop, which would be worst than any stock processor.

 

So CPU is hard to overclock but GPU isn't hard at all correct?

 

So since laptop CPUs are plenty fast enough to handle any and all comers, but the GPU, HDD and RAM tend to bottleneck...I can't overclock the HDD and the RAM wouldn't be worth the risk...The 8600M GT overclocks well and I will be able to get another 3-4 months out of my G1S. Thanks all.

 

I agree with the CPU being fast enough. However just like the GPU being the bottleneck in most cases for gaming, CPU also can increase gaming performance even though the RAM and HDD can be the bottleneck. Harddrives should be excluded from the equation since most gaming wouldn't require the information since all textures would be loaded directly into memory system of the graphic card and system memory. More performance from the CPU would always be welcomed in my view

RAM overclocking would be ideal since your directly increasing system bus frequency from 667/800 to 1000+ and beyond just like the desktop overclocked counterparts and would definately increase performance to unseen level, but this also non-existant in the mobile sector. Probably worst than CPU overclocking simply because the notebook memory modules are small enough already, and increased memory speeds would increase heat as well ( see heat spreaders on performance memory in desktops), and the increased frequency would require more power/voltage.


GPUs are easier to overclock thanks to the graphic card manufacturers and third party software apps but cooling graphic cards are far more difficult to apply for laptops. You can't simply modify or change the cooling systems since the design is often custom made to fit specific laptop design and often tied with the CPU.

HDDs aren't overclockable as far as I know in today's architecture. I believe they still working under the 66mhz bus or 133mhz PCI-E in recent chipset architecture. I would have to read up on that to verify but I don't think the increased bus speed would increase performance since the bottleneck is actually the drive itself and not the transfer speed.

 

It's not that it's hard. It's more like is it "possible"? For example the Sonoma/Pentium M architecture as well as the Conroe/Core 2 Duo architecture in laptops would allow overclocking to a certain degree.

GPU is relatively easier but your only working with software and absolutely no hardware changing. You can't swap GPUs on dedicated graphic cards in notebooks (except MXM of course).

 

I saw a benchmark thread that included an overclocked 8600M GT that claimed you could overclock the GPU over 50% and it remained stable...i cant seem to find the link now tho...
