I have a pretty regular system.
Hewlett Packard Pavilion A316n
2.4GHz Intel Celeron Processor
256MB DDR SDRAM Memory
80Gb Ultra DMA Hard Drive
CD-RW/DVD-Rom Combo Drive
Intel Extream Graphics with up to 64Mb Sharded video memory
Windows XP Home Edition
If by "regular" you mean the inadequate and overpriced fodder that the big firms feed to the masses, yes, I would totally agree.
I want to overclock & push my computer as far as it will go.
That would be reasonably simple had the manufacturer not messed up an otherwise reasonable technology with their inane policy of disabling most overclocking features on the mainboards they distribute.
Actully I am pretty satisfied with the specs I have.
The reason you are satisfied is because you don't have the knowledge, need or experience to determine otherwise. What you have is a very poor system indeed compared to the likes of which is suitable for modern Flight Simulation use.
I just like to do everthing top notch.
That is not evident from your choice of system, however, this again reflects lack of knowledge, stick around these forums and learn more.
I wanted to O/C my pc to force it to run at it's best.
Unfortunately, "it's best" is not going to rate amongst the PC's that most people here use. I'm not being snobby, just trying to bring about some awareness on your part. If you actually saw what a decent system is capable of, you would surely be amazed and start to understand what I'm talking about.
At a BASIC LEVEL, the PC's chipset will determine it's overall potential. That means the mainboard must be right.
Next, a celeron CPU is not a suitable type for gaming-simming.
256mb of RAM leaves your rig starving for memory and precludes any performance characteristics possible.
Intel Extream Graphics STEALS, not "shares" up to 64mb of video ram from your system, thus knocking your available ram back to practically zilch..... besides the fact that "onboard" graphics and lack of a dedicated video card are paramount to a performance "dead end".
256mb total less 64mb = 192mb less 124mb for windows to load = 68mb........ not exactly a performance rig and exactly a very poor one.
I hope this has been somewhat informative, and I'm sure plenty in these forums will be more than happy to help you learn more.
If you are used to paying Hewlett Packard prices, then you will find solice in these forums, as there are price competitive solutions available.
If you expect to turn a sow's ear into a silk purse, then I fear you risk disappointment. ;)
