Upgrade beyond limits

Not sure what you are asking about. Asus site says the motherboard will take DDR2 533/667MHz SDRAM, 2x SO-DIMM socket expandable to 2GB
Which means DDR2 533mhz 1 gig per slot total 2gig
or DDR2 667mhz 1 gig per slot total 2 gig

To enter BIOs press F2 at boot up, but no setting should need to be changed.

They do not have a BIOs update for increasing the memory limits.
BIOs upgrades from first to current are.
BIOS 304
Update new CPU Microcode
System plays wave file and causes garbage sound.
BIOS 305
To fix system cannot do battery pre-charge process when an unknown/failure battery insert.
Support Intel Extend ID CPU:Merom Celeron 530 CPU.
BIOS 306
To fix system cannot do battery pre-charge process when an unknown/failure battery insert.
BIOS 307
Fix System hang at ASUS LOGO on SATA HDD with factory recovery image
Last upgrade date is 2008 7 14

First, have you ever changed/upgraded a CPU? It take quite a bit of research to upgrage. If you look at this spec of the Mobo your options are very limited, The Mobo only supports 2 different type Processors, 1, Core 2 Duo (Merom); http://ark.intel.com/products/codename/2683/Merom , 2 Core 2 Duo (Penryn): http://en.wikipedia.org/wiki/Penryn_(microprocessor) If you have a 64bit OS consider a memory upgrade, if you haven't already.

According to the specs I have Serena, the eMachines eTower 633i Desktop PC, uses a TriGem Cognac motherboard.

[TriGem is the manufacturer, Cognac is the model.
Note it is Not the TriGem Cognac+ ]

PDF motherboard manual,

Click on - Cognac - in the left side of the list.

Going back to the Motherboards.org page;
(Nothing like upside down photo information, and the motherboard is turned 90 degrees to the Right, to how it actually sits in your computer case )

The processor socket is a Socket 370,

http://en.wikipedia.org/wiki/Socket_370

Used for Intel Pentium III processors, and intel 'Celey' processors.

(Excuse me......Celeron.
An Intel Pentium III processor has TWICE the L2 cache, that a comparable Intel Celeron has.
The cache for a Processor is a small memory area for the Processor.

It is the First memory the Processor accesses.
The Ram Memory is second, and the Harddrive is third.
More cache for a Processor makes it more faster )

The motherboard chipset is an Intel 810.

The Northbridge chip of the motherboard chipset, is an Intel 82810.
The Southbridge chip is an Intel 82801AA, or an Intel 82801AB.
(Intel ICH, or Intel ICH0 )

Looking at the chart, and reading across, you can see what the Intel 810 motherboard chipset supports;

1) Processors: Intel Celeron, or Intel Pentium II, or Intel Pentium III.

2) Processor Front Side Bus: (FSB) 66MegaHertz, or 100MHz.

3) SDR Sdram ram memory at 100Megahertz.

[Single Data Rate Sdram is often just referred to as Sdram.

Erroneous.
Double Data Rate Sdram is also Sdram (DDR Sdram)
Synchronous Dynamic Random Access Memory
So is DDR2 Sdram, and DDR3 Sdram ]

Also referred to as PC100.

So when looking for a CPU you look for;

1) Fits in a Socket 370 processor socket.
Yep. The best is going to be an Intel Pentium III.

2) Has a FSB of 100MHz.

Hmmm,............

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_III_microprocessors#.22Coppermine.22_.28180_nm.29

Scroll down.

Pentium III 1100.

Maximum frequency rate ('Speed') is 1.1GHz (1100MHz)
Front Side Bus = 100MHz
Uses a Socket 370 processor socket.
Part Number = RB80526PY005256
sSpec Number = SL5QW

[ Don't forget to follow Anti-Static Precautions.
Clean the bottom of the Heatsink THOROUGHLY, and the top of the Processor if it needs it. (I always do anyway)

PROPERLY apply fresh, new Thermal Paste.

you can check out this web site.

According to PCChips, the maximum CPU & memory supported for all three is the Intel P4 Northwood (HT) 3.06 GHz 512K,533FSB,Socket 478 and 2GB (2 x 1GB) DDR 266.

Be sure you have the latest BIOS version for your motherbaord.

M925ALU (V7.3) must have BIOS : 030703s
M925G (V8.0) and M925G (V9.1b) must have BIOS : 050510s

Hope this helps you out.

Hope it answers your questions.

download cpuz it will tell your specs

you could only upgrade the processor and RAM in this condition i.e.

you can only change your an upgraded p-III processor like 1.0 GHz, 1.1 GHz or 1.3GHz and
upgrade the RAM by changing to 256 in each slot.

that is all what u can do with ur pc

Sounds like the processor you're trying to upgrade to isn't the same frequency. The processor, motherboard, and memory have a matched frequency. For example; a motherboard with a frequency of say PC4200 will only accept a processor and memory of a PC4200 frequency. If you try to use PC5300 memory it basically won't do anything, blank screen, or maybe a beep. The same if you tried to use a processor with PC5300 on the PC4200 board. The best way to find the frequency rating is to look on the memory. They class the memory by frequency, but rarely ever list the frequency for the board or processor. Research the new processor to find out the memory class and then see if it matches the memory in your machine. If it doesn't then the processor won't work. If it does, then new processor may not be compatible, and that means more research.
