Solved Will BIOS update help oc my pc or not?pll#

Specs: Windows XP sp3, Sempron/1.5GBram
I am trying to figure out whether I should buy eSupport service to update my BIOS since I can't access the multipliers in this eMachines.

CPU Type AMD Sempron, 1800 MHz (9 x 200) 3100+

CPU Alias Winchester-256 S754

Motherboard Name FIC K8M-800M

Award BIOS Type Phoenix - AwardBIOS v6.00PG

Anyway I heard here, that Semprons and AMD's from that era were good for overclocking with stock fans, my case is usually at 40 I installed one additional fan to cool the cpu, so it's helped keep the temp stable, just because I want to get the most of it for now. I downloaded clockgen software to access FSB directly, but I could not find any pll number when I opened the case.
System BIOS Date 05/11/05 .. esupport driver agent scanner says there is a BIOS update available, does anybody know any other means to gain access to the FSB, and will an update help do that. I am not really planning on spending on actual hardware anymore since this is a pretty old pc.

Sorry, it will not help you. Machine manufacturers use custom hardware so you must use only their BIOS updates (so don't go looking around) but because of the economy nature of the hardware that they purchase, they lock down the settings so you cannot cause equipment failure that you would blame on them. They do not want to be responsible for replacing hardware under warranty due to an over zealous enthusiast over doing the settings on their marginal hardware. It may be that the CPU you have is very overclockable, but not unless you purchase an aftermarket motherboard, which as you pointed out may be throwing good money into an older system that might only see marginal improvements, especially since you would probably end up adding a graphics card, better power supply, better memory to support the new board and keep up with the overclock.
Summary: save it for a new system. If you are interested in overclocking, you really need to build it yourself to get satisfactory results.

You have to be a little bit crazy to keep you from going insane.

A BIOS update for your computer must come from eMachines. Such an update should only be done if it specifically addresses a problem you are having. I strongly doubt than an update would allow access to overclocking settings.

OEM computers do not stand up well to the extra strains imposed by overclocking. The manufacturers try to prevent this by omitting these settings from the BIOS. This protects you from failures and them from the resulting warranty claims.

Overclocking is best confined to home built systems where you can control the quality and specifications of the components used.

✔ Best Answer
Just to add, you should NEVER pay for a BIOS update (or for drivers). They are always free from the manufacturer.

As for overclocking your CPU, all AMD CPUs (other than Black Edition) have the multiplier locked from being raised higher than the default, it can be lowered though. Also, please get the terminology correct. AMD doesn't use a FSB & hasn't since the days of the Athlon XP. What you're referring to as "FSB" is the CPU reference clock. All AMD CPUs since the very 1st Athlon 64 to the latest Phenoms use a reference clock of 200MHz.

To properly overclock your CPU, you will need to be able to do the following:

- increase the CPU reference clock
- lower the CPU multiplier
- lower the HT multiplier
- lower the RAM speed
- lock the AGP at 66MHz
- disable Spread Spectrum
- adjust CPU & RAM voltages

If you're willing to take a chance, you can try cross flashing to the FIC BIOS, but you'll risk trashing the board & making it completely useless. Everything you need can be found at the FIC website:

Thanks for the advice, I was wondering whether I should have invested into an aftermarket mobo but obviously it might require additional to be invested into a psu, likely another cpu fan.. and it's just not worth it, but i will check out the information you guys gave me, FIC seems to be "out of touch" and in my opinion not an OC friendly company since they mass-produce these for companies like Dell, emachines, and the like..

I flashed the mobo directly from eMachines last year which is why I came here. mickliq, thanks for the info. . have anyone of you cross flashed a mobo successfully? I might try that, but I'll try the link mickliq sent me, the link to download the driver itself is dead but I'll contact the poster.

Yes, I have flashed a S754 eMachines board (FIC K8MC51G) to a modded BIOS. It is now fully overclockable. I have also cross flashed an ECS board to a Biostar BIOS to get the 1T/2T option for memory settings. Both boards are still functioning & I've had no problems with either.

mickliq what motherboards do you consider might be compatible to crossflash with mine the FIC K8M-800M, I suppose a modded FIC model, I will make a shortlist..

Do you have a quick guideline to find the right bios to cross flash to make the search better?

Thanks to everyone for responses so far.

Update. I contacted the poster about the modded Emachines T3104 VVC09EM but no response.
