G1S-B1 CPU Question....

Can you upgrade the cpu to a penryn cpu?

 

I thought I had heard that the Merom and Penryn chips were supposed to be pin-compatible, but I could be wrong.

You'll need a BIOS update to support it, and obviously a cpu upgrade instantly voids your warranty.

 

G1S is Santa Rosa, not Merom, right? And those two aren't pin compatible... or aren't they FSB-compatible?

If Santa Rosa NOT Merom, but Merom YES Penryn, then Penryn NOT Santa Rosa.

Oh boy... I think I need to get some sleep

 

^WTF? Most confusing post I've read in a while.

Penryn is pin compatible with Santa Rosa, which is not pin compatible with Merom.

 

Thanks, that clarifies thing a bit (my post didn't do much in that direction, I'm afraid).

 

On Asus G1S support page, there is a new BIOS upgrade that brings Penryn support to the G1S amongst other things...

The new bios (300) is specifically for upgrading the motherboard to accept Penryn. The pins will match up as they are the same socket as the T7700 in you G1S B1. You won't see a lot of difference between the T7700 and T9300 though. From what I have read so far, it will be slightly faster encoding (few seconds), a few degrees cooler, and a few more minutes of battery life. You would also instantly void your 360 Warranty from Asus. All that for $350 and some change. It doesn't sound worth it to me.

 

This clears alot up for me. I wish that Asus was better with updating info for its owners...

 

if in three years i can just add a penryn for a speed boost instead of buying a whole new lappy, itll be worth it. for now, my t7700 flies compared to the p4 2.8ghz i was using for four years prior, so im good.

 

hmm than would the G1S-X1 be able to use the Penryn Processors?

 

I believe that the T7300 uses the same socket as T7700/T8xxx/T9xxx. You would have to update your bios to "300". Check out this blog for instructions. Read carefully before attempting as updating a bios is not to be taken lightly. http://asusg1s.blogspot.com/2007/12/upgrading-to-bios-300.html

 

yea..iv updated to v300 a few weeks ago..im just thinking if i should get the processor or not, will ASUS help u change if i bring it to them because if i change the processor wouldnt it void my warranty?

anyway wat u you guys think about upgrading the processor?

 

Asus does not perform upgrades on consumer's notebooks. Any CPU upgrade requires that the seals be broken, thus immediately voiding your Asus warranty.

 

rulebreaker: Well are you running CPU-intensive tasks on a regular basis (I'm not talking games, there the bottleneck is usually the GPU)? If so, it might be worth it and you need to weigh the speed increase against the cost.

Otherwise, it's certainly not worth it.

 

If you use your G1s for gaming primarily, upgrading from a T7300 is not going to give you that much performance increase. For example- run a performance monitor log while you are in your favorite game sometime and check it afterwards. I bet you will find that your processor cores are running between 45% and 75% of their full potential. So unless your processors are maxed out you will not see any performance increase. Realistically the bottleneck in your system is not the T7300 processor. It is the 8600GT. Nothing against the card but that is how it stands. Encoding on the other hand would would be an example of a CPU intensive process that you will see a performance gain in. So it ultimately depends on what you use your laptop for the most.

 

well..iv completed crysis already, but will the new games require alot of CPU power, and will the graphics card still be powerful enought to play the game? because if i upgrade my CPU the graphic card might not b powerful enough and the GPU in the G1S cant be changed..soim not sure if i should change.

 

I really think we are good for a few more years... Crysis is not a good example of games to come. I think Crytek (makers of Crysis didn't make a good job optimizing it's engine.) It was thought out for ~$4K USD game rigs and even then they sometimes choke!

There are other games that look quite as stunning as Crysis and perform much, much better, for example Call of Duty 4.

yea..completed call of duty 4 too, waiting for new games now..so the upgrade would be worth? which penryn processor model would be a good upgrade?

 

Yeah, 3D programmers are really relaxed with their programming, and make a poor job of it relying on the fast hardware to do their work for them. But even for this, the bottleneck is the GPU and not the CPU.

Hopefully the advent of notebooks instead of desktops will eliminate the gaming rig as the main target of game developers, so they'll start paying some attention to their programming quality...

Rulebreaker, in case we weren't clear enough: it's not worth your money to upgrade the CPU at this point. You will see almost no real-life benefit. Stick with your current CPU, and save the money.

 

I totally agree with you E.B.E.

@Rulebreaker, The CPU upgrade will only help on other tasks like video encoding, ripping, video post-processing, image processing, file (de)compression, etc.... Stuff like that, and then again it will only be a marginal performance increase.

Hey guys, interesting thread
I was wondering, a couple months ago Intel rolled out some sort of quad core CPU for laptops, could one replace the 7x00 processor in the G1S with one of those or would the thermal requirements of the CPU be too high? And is the socket even compatible?

Tnx

 

that's a great quesiton.....i'd like to know that too, anybody?

 

So does anyone have any idea about this??

 

I have no idea, there would be several things that need to be satisfied:

1. Pin layout has to be compatible.
2. Chipset must support the CPU (FSB etc).
3. CPU microcode has to be in the BIOS.
4. The TDP of the CPU must be supported by the cooling system.

 

As I recall, Intel anounce a quad mobile chip based on Penryn or Nehalem in their roadmap coming out at some point later this year or early '09. All of EBE's comments remain requirements for it to work, and remember that replacing a CPU within Asus' warranty timeframe immediately VOIDS that warranty.

 

@E.B.E

In that case, what's the point of Asus rolling out a G1S Bios update that clearly claims Penryn support among other things?

Cheers!
Rayan

 

Well that means that Penryn is supported. (releasing a BIOS update means pretty clearly that the hardware requirements are satisfied)

But the OP was asking about some quad-core CPUs? I'm not sure those are the typical Penryns. Also I didn't say they would not be supported, I just said that I don't know and that those are the requirements that are needed to support them.

 

I dont see much advantage in trading my CPU (T7500 w/2.2GHZ) for one of the new ones... as the speed gain would not be that impressive... and the costs for doing it would be WAY too high!!!

However, when a quad-core CPU were finally out for notebooks.. Well... that's a whole new different story! Cause IF my G1S specs could actually support it (even by doing some little tweaks), that would definitely worth the shot!!!

Don't you think so, ppl?

 

Yeah, a quad core will give you a massive performance boost in lots of applications as well as video games where the CPU is used for processing the physics of the game e.g. Alan Wake

 

Only assuming that these applications use multi-core processing. Not many of them do nowadays...

 

Correcto!
