I cant understand why Intel would not set the Extreme version at 4GHz,Everyone seems to run the i7 920 at 3.8 to 4.2 GHz, why announce a 975 at 3.33GHz?

Is it a name brand PC, like Dell, HP , if so the bios generally does not allow for overclocking.If not what Motherboard do you have, I assume the stock CPU Fan?

Agreed, HT OFF also allows me to run 4GHZ cooler at lower voltage, I only turn it on for video encoding.Thanks for the Toronto comments, seems the areas I've been using for stutter testing need tweaking on even the best systems.Yesterday, I setup FSX Accel on:i7 4GHZ HT off, x58GTX280Win7 Beta181.20 drivers, 16x AFFSX AF, AA ON, TBM 70The base install flys Toronto smooth with 19m terrain, 60cm textures, SC max, AG dense.Made an image and will slowly add extras, and tweak FSX trying to keep things smooth.In the past I was just moving my full FSX installs around.There was too many varibles between hardware, OC settings, drivers and FSX and addon settings.It was all but impossible to find a specific reason for stutters on any given setup.Hoping building slowly on a fresh install will work better.First addon will be GEX to rid those blurry sandlike distant default FSX textures :)

Driver, 3d Glasses and a normal LCD 60Hz monitor = 3D ???Looking at the driver it mentions the need for anaglyph displays or special hardware displays?Seen other people saying you need a CRT at 100Hz or more?Supporting GeForce Stereoscopic 3D Displays•Passive polarized stereo displays◦Zalman Trimon ZM-M220W (22 inch 1680x1050)◦Zalman TriMon ZM-M190 (19 inch 1280x1024) ◦Zalman HDTV LCD (1366x768)•Anaglyph display with red/blue stereo glasses

Finally found a decent i7 / gtx280 base setup for smooth flight:Win7 64 Bit betanVidia 181.20 Drivers, AF 16xFresh FSX Acceleration install, AF AA checked, 19m Terrain, 1m TexturesFSX.cfg changes:widescreen onTBM = 70Thats it.Finally a base that produces stutter free and artifact free flight flying LOW over Toronto with SC and AG turned up.Made an DiscWizard image and now to slowly install addons, and different FSX and GPU settings. My lesson is alot of the FSX tips used in the past on core systems do not work well my evga/i7/gtx280 on any OS, as I tried them all thanks to technet plus!Bufferpools being a big one that comes to mind, and also setting textures to 7cm.Not sure about the usual nHancer suggestions either. As with this setup I just turned AF/AA on in FSX and used the Nvidia CP to set AF to 16x. Its giving very nice IQ that for the 1st time is stutterfree.LOW flight stutterfree over cities is the most important benchmark to me.Bufferpools resulted in graphic glitches galore, and textures at 7cm resulted in stuttering and annoying texture resolution poppingand often blocky textures when close to the ground in the other i7 installs I tried.

Any chance of releasing your manual install version now :)Most of us here are content editing configs and manually copying files as needed,in fact many of us would rather do it that way to keep control of things...Just a thought your previews look great!

I'll have to try those 180.20 as well, as my new i7/gtx280 is stuttering as well when I'm low to the ground or making turns.I've been defragging, trying different OS's etc without a perfect solution.I've tried Vista 64, XP 32 and XP64 of them all strangely XP 32 seemed the best,but its hard to tell with so many variables in setups.Vista 64 was the most problem prone, with stutters and flashing textures, etc.It's my main OS so I'd like to get it working.Here's what has helped Vista 64:+ Removed the bufferpools entry in fsx.cfg+ Space / Name defrag per Nicks tips+ Run settings at 19m terrain/ 1m textures, 7cm textures seem to increase stutters flying lowStill not happy with the i7/280 Vista 64 setup for FSX but its improving...Note my old 280 worked fine with FSX on a quad core.Simple test I do is fly about 500 ft or so above a runway, with the new setup the runway numbers flicker/stutter its very easy to see.Vista 64 is fine otherwise but unless you run a lot of add ons with FSX I'm not sure its that different than a 32 bit OS?

Wow, its been a while since I ran FS9, but tried my old install on the i7 today,sure this is old news but...Could not believe the performance, you can max every setting,set AF to 16x, AA to Combined 16xS, and put VSync on, and lock at 60fps full refresh rate everywhere.But its the smoothness that is just amazing after running FSX for months.FS9 on the new system is perfectly smooth in every city and area I try it with.Flying high, or low, it just works.FS9 textures fall short of FSX but the smooth 60fps vsynced performance is remarkable.

Has Toshiba's dropping of HD DVD made sales of HD DVD titles increase?

Actions speak louder than words.No development, no staff, no future.Can't see them selling it to someone either, that would have been done before letting the staff go.FSX will continue to have a shelf life but with a declining active user base and declining add-on interest.Add on interest seems to have declined already, look at the response to ManhattanX here, about 10 posts.I think MS seen the writing on the wall, and made the future clear.

Developers want MS to be clearer?MS completely shut down FS development and let go all related staff ....seems clear to me.It's over.

No you need a fresh install to go from 32 to 64 bit.But if you want to try an quicker 'fix', just buy 2GB of more memory for your XP 32 system and add NickN's OOM fix.http://www.simviation.com/cgi-bin/yabb2/Ya...?num=1199566076http://www.simforums.com/forums/forum_post...&PID=138287If that does not work then go to a 64 bit OS.

Use a standard tool like cpuz to check your vcore, it will always be somewhat different from the bios setting.Read about vDroop and Load Line Calibration, they impact the difference as well.

Another area I fly ... Toronto, Canada seems to produce a high number of stutters with Scenery Comp at 100%.HT on or HT off.Try taking off east from the Toronto Island Airport and quick fly north low over downtown,then swing back to land on the island.Stutters, stutters, stutters, even with a fresh XP x64 install. I dont recall seeing these with my older quad core setup, maybe I'm just expecting more with i7.Other areas are fine with the i7, but some cities seem to give more pronounced stuttering.They are seen with 64 bit OSes, seems lesser with XP 32, but its hard to prove, might try video taping them and playing back side by side.

Faster indeed.After a DiscWizard restore, O and O showed the drive as fully SPACE defragged graphically and running a SPACE defrag was all but instant.DiscWizard is based on the newest TrueImage, maybe something has changed.It backs up file by file, then it would restore file by file as well, should be space defragged?The file order is probably close to the directory layout too?Not sure what tool to use to find out?Give it try, it can be a lot faster than multiple defrags on many drives .Another topic...In O an O 11, running SPACE, NAME, the SPACE, the last space seems to mess with the NAME ordering?After the SPACE , NAME were complete the graphical image showed a large white space area in teh middle.Running SPACE again, filled the white space,but ..watching the final SPACE run, it appears to grab blocks randomly from the layout.If its already in NAME order, I'd think it grab them in order?

Any know if you make an image of a drive using True Image and then restore it,will it restore on a file by file basis... resulting is 100% space defragged drive. Might be quicker in some cases than running multiple space defrags.For that matter I guess it may also restore in Name order too?Not talking about the sector by sector image/restore just the normal one.P.S Seagate offers a free tool, Seagate DiscWizard, based on True Image that does pretty much the same as long as you have a Seagate or Maxtor drive in the system.

The i7 XP install just broke the 10 sec barrier in SuperPi 1M as well!It's a 32bit XP Pro and the eVGA board can only recognize 2GB of ram with 32bit OSes,a new bios might up that to 2.49 but the new bios has OC issues for some.Think I'll try a XP 64 install never used that before, glad I joined Technet or all these OS's would break the bank.Anyone having FSX micro stutters on a eVGA i7 Vista 64 setup you might want to try XP,or maybe we can find what the Vista issue is. I going to try to compare all my drivers in both installs.I can tell you the difference for me is night and day when I fly smooth vs seeing the micro and major stuttering.Back on topic with XP 32bit, and HT off all is smooth, no AF mask entry needed, 4.1GHz.

Stutter problem seems to be due to my Vista 64 install, 1st time I used V64 with the i7.Maybe some driver issue not sure. I cloned my XP FSX install from the old machine, installed new drivers, and guess what... smooth on the i7.

Thanks for the tips again Nick, I can take this to another thread if you like, but I'll ask here since its based on your suggestions.Noticed something... When I set the frame rate to unlimited in RJTT test flight, I get massive black spikes and flashing textures when doing the initial fast pans around the plane.If I set the frame rate to 24 no artifacts during the pan.Anyone else notice the same or is that sign of a hardware or cfg issue?

Nick - Toyko is tough indeed, but its one of the few areas I can come up with that always stutters at some point.Maybe you or someone can suggest another test area so we all can try the same area?I can't say I see a clear difference with HT ON and AM=255 or HT OFF and AM=15.I can get a higher CPU clock at lower volts with HT off , so that should help FSX in general.I find the Task Manager CPU usage charts strange with AM= 15 or 255, where cores 2,3,4 all graphs look the same?

Alphahawk3 - thanks for the feedback, so HT off and affinitymask=15 works best for you. What area is a good test to show that for you?David Roch - What area are you using to test?Nick - can you comment on the RJTT flight I posted, does it stutter on your setup?Overall while the i7 clearly offers higher fps for me, when it stutters its more noticable, would like to solve that somehow...

Here's a saved flight that produces stutters with the i7, despite changing settings.http://members.shaw.ca/HD_IMAGES/files/rjttstutter.zipIt uses just a C172 flying out from RJTT , an area where very few have extras installed.The flight was saved mid flight, auto pilot is on.Stuttering for me starts right off the bat.After a couple minutes when the stuttering stops,try turning auto pilot off , and make a sharp turn,which produces stuttering again during the turn.Love to hear if any others are able to run it smoothly and suggested settings...If that area is too busy, maybe others can post a suggested stutter testso we all can be on the same page when we report on this issue.

It reduces stutters with HT on , off, or it does not matter?

252 makes sense to free a full core...test for stutters at rjtt fly low...

NickN - so what vcore did it take to burn out a 920?
