FSX Problem

[ukmil]

i had same problem a few weeks back, and it was a faulty power supply

[tonymadge]

I had to upgrade to a 900W

So FSX is not Global Warming Friendly..eating all those Watts...did they mention that on the box?? Well guys prepare yourself for a visit from the Greenpeace and tree hugger party who will picket your home and demand you recycle more... I recycled my FSX to Dave and reused FS9... I think I will vote Green Party next election

What sort of temperature should a chip operate at? I flew FSX for about 10 minutes last night and it got to just over 60.

Depends on the chip mate and what its doing. Thats a bit like asking what temperature a car engine should be... it would depend on the engine and what its doing. ;-)

Should tell you if your chip is running hot, but 60C is well within normal operating range. I had a similar problem last year and it turned out my quite pricey 550W PSU was dying as one of the cooling fans in it wasn't connected, the fact it had lasted so long without cooling was a testament to the quality of the design but did make fault finding a bit of a problem!

Well I just got dumped again and I noted the temperatures on re-boot. There are 3 temperatures called IT8718F, the first is 74, second 42 and lastly 25. The 2 intel cores are reading -40 & -41?!?!? The graphics card is showing 66. Do any of these make any sense to anyone? Or does it look like a PSU issue? Cheers chaps.

Having just run it again & got binned, both cores are now showing around 80 degrees.

That seems very hot mate. Its probably that the heat sink is not properly attached to the cpu. Once it becomes detached, it needs to have new compound applied, reseating on the old compound isn't reckomended. Just out of curiosity, what motherboard is it?

[RobDob]

Its an ASUS® P5N-E SLI: Quad-core CPU Ready, NVIDIA® Dual X8 SLI. Are you suggesting I need a new CPU? Is it very obvious if the heat sink is becoming detached?

Hi Rob,

I also have an ASUS board, with a quad core CPU running at 2.66. ASUS have a utility on their website called PC Probe II which shows you all the temperatures, voltages, and fan speeds. I'd suggest using that utility as it is actually written by the manufacturer and not an interpritation of the Systems management chip by someone else...
Got FSX running at the moment with Ricks hawk through "The Loop" with Genx. All 4 of my cores are running full chat (between 90 - 100%) The CPU temperature peak is 65, but averaging 60 - 62. Now thats with 4 cores. Bare in mind that there isn't a "temperature per core" and if something is reporting that its largely bollocks. There is a thermistor on the board, usually bellow the cpu that monitors the cpu temp, so you will only see one temp. when FSX is closed and I'm siting typing into the web browser, the cpu temp is 39 - 43.

There is another temperature sensor on the board for monitoring ambient motherboard temperatures. On my system this has stayed at 31 -33 throughout.

It won't be obvious if the CPU fan isn't seated properly, as they are clipped on fairly snug, but its the special gunk between the two that actuall transfers the heat from the cpu to the heat sink, and the best thing to do is take the heat sink off , clean it and the top of the processor and apply new stuff.

It could also be the CPU fan playing up, and PC Probe will show you what the RPM is. as a guidline, mine is spinning at arround 4100 rpm when at full chat, and drops to about 3700 at the minute.

Your CPU shouldn't be damaged. even if it is getting up to 80... that is probably within safety margins, but it won't do it any good.

I've just uploaded ProbeII to our webserver here as it will be faster than ASUS's. Download it from this link...

Uninstall the other utilities first and let us know how you get on.
