    We just posted part one of the how to on uploading new files to the Library. Part 1 covers adding new files. Part 2 will cover making changes to your the uploads you own.


    Questions or comments please post them in the regular forums. Which forum is that... Well it is the one you spend the most time in.

Ive got a QX9650 overclocked to 4.0 and its pretty stabile. What would be your recommendation for the cpu voltage. Im running vista 64 with an 8800 gtx with 4 gig of ram (1100) duel channel on a asus stiker II formula MB. Running 2 250 gigs in raid 0. Got a 900 watt tagan ITZ series PS. The cpu is water cooled along with the 8800 gtx (2 of em) but I dont use SLI. The reason why I am asking is that every so often the sim just freezes, and Ive got to manually reboot to get windows to load up. seems to only happen when I get up to about 3.8 ghz and above. I tried the newer drivers 180. series But had alot of crashes. Im running 178.24 drivers becouse they seem alot more stabile. Any input would be great.

Thanks In Advance

You can push it to 1.645 but I would not go past 1.5v on water

AT 1.435 and 4.20 GHz it should be very stable
 
The QX9650 is a great chip. I'd mine running 24/7 at 4ghz with the bios voltage set at ~ 1.43v (4.5ghz+ should be possible with adequate cooling). For comparison, my QX9770 is running at 1.45v. You need to allow for voltage droop (V Droop) when overclocking.......some boards seem to be more suseptible to this than others. Use CPU-Z to get a more accurate voltage reading....and keep a close eye on cpu temps when upping the voltages. :)
 
4.5 saweeet. I bumped it up to 1.4v at 4.0 ghz and seems good, any advice on overclocking ram, I was told that overclocking ram does nothing for FSX ?

Ideally the ram mhz should match the cpu's FSB mhz rating.....in this case 1333mhz. I tend not to overclock the ram too much as it's all to eay to fry it (which can prove rather expensive with 2gb DDR3 modules!!:isadizzy::costumes: ). Investing in a memory cooler would be a good bet too.:wavey:
 
I was told by a hardware guru (in case the name "Nick Needham" doesn't ring a bell) that FSX prefers a 5:6 ratio between FSB and Ram frequency combined with low memory timings.

Since both of these elements work together, try setting your Ram frequency first and then adjust the memory timings for a stable and fast operation.

Personally, I managed to reduce my Ram latency from around 85ns to 64ns with the right settings.
