I have the following rig

ASUS PK5PRO
Q9300
8GB A-DATA DDR2 800
320GB SATA
512GB 8800GT
DVD+RW
1 EXTERNAL 1TB HARD DRIVE
2 USB CONNECTIONS (KEYBOARD/MOUSE + JOYSTICK)

OS: VISTA x64

NO OVERCLOCKING DONE

The rig is powered by a 450W PSU. My question today is, is this PSU enough to cover all equipment ?

FSX is jerky during turns at airports, never >10 FPS and I thought possibly the GFX is underpowered and causing this.

I have followed all your guides and tweaks, numerous times over (installed, re-formatted, re-installed) I have no add-ons.

Thanks

I don't know about your question, but NICE RIG!!!

Thanks FuturePilot although I keep second guessing my choices for the GFX as well as the RAM.

I'll risk having Nick scold me ,,  :D

While the video-cars is a bit dated, I don't think it's a real bottleneck for that CPU (un-clocked)..

The power supply however, is on  the small side.. I'd think that 750 watts would be bare minimum there.

Hi

Your PSU should be fine, since you are not locking up or crashing.
It is a bit low at 450W, but if it wasn't enough, you would be having real problems.

If you are in doubt, add up the required power for all the components in your system and see if it is under 450W.

I too thought my rig was capable of handling at close to max on the sliders however with Nicks recommendations at the lower end of his suggestions iI still get these jerky movements while turning over large airports.

How much AI are you using?

Oh and Welcome to Simviation

thanks for the welcome.

AI is set as per NickN for low-end desktops.  When I get home I'll post pics of CPUZ as well as the settings for AI etc.

thanks for your help.

btw are your rigs/fsx installs running smooth without jerkyness etc?

btw are your rigs/fsx installs running smooth without jerkyness etc?

Pretty much yes, but I do slow down over big airports. But it isn't really jerky, just lower frame rates. I have them set at 24 and it holds that fine most of the time.
I fly mostly low level VFR, so I have ground traffic up to 100% and only like 5% airliners and maybe 35% general. I would rather see the world looking alive than to have a lot of planes flying around. Big airports look very lonely though. I take a serious hit if I try to get a lot of action around a big airports.

I am not at home and can not log onto the forums so I asked Dave to post this for me


I am sorry to say that rig is not what I would call a good FSX tower and yes the system is underpowered.

You need a better PSU but do not expect that to make everything run better.. It may help but the bottom line is that system is a medium at best for FSX if its not clocked.

This unit is 80 dollars with a rebate and is in line with what you need

If you ever intend to get a better video card and clock, you need this unit which costs 25 dollars more

Your issue is the memory timing., CPU speed and last the video card

8GB of memory is doing nothing for you.. AT ALL. More than likely to use 8GB the system is running the memory timing high which chokes the CPU communication. @ DDR2 800 you should be running 4-4-4 timing at MAX. Use CPUz to see what your system is running.. the memory tab will tell you the timing and speed.

Good Luck

Nick many thanks for your reply. I really appreciate your expert comments.

In your opinion would increasing power to one ofe the PSU's you listed as well as reverting to a XP OS as well as dropping the memory from 8gb to 4gb (what is your recomendation here?) help. I am little worried regarding overclocking especially when temp needs to be controlled. I have a CA-T05 case (coolermaster) with a noctua cooling NH-U12P that takes up most of the case (2 fans, 1 chasis, 1 cooling. I believe cooling would an issue in my case.

Any thoughts?

Cheers

You need a better PSU with a quad and a 8800GT, no doubt about that.

I question the memory timing and speed here because of the 8GB of generic memory

Use CPUz and post the CPU, Mainbaord and Memory tabs here

I need to see the GUI tabs, not the text report

Hi Nick here are the screenshots







what timings would you recommend for RAM and CPU?

thanks again

Sorry Nick I forgot the mainboard tab

The timing one wants at DDR2 800 is 4-4-4

You are running 5-5-5 which is not as bad as I anticipated but its still not the best none the less.

The memory product is not rated for 4-4-4 @ DDR2 800 (400MHz)


Your best bet is to get a proper PSU which is required no matter what in this. And after that perhaps try a bit of mild CPU clocking. More than likely the memory will never allow you to run it at 4-4-4 even if you remove 4GB of the 8. You could try it however its highly unlikely.
