May 11, 201214 yr Most games and flight sims run perfectly @3.5. I remember you - the guy that doesn't like to OC... while I don't have an issue with that, you shouldn't make blanket statements such as "most games runs perfectly @ 3.5." I can tell you in my experience the difference between 3.5 and 4.4 is massive when you start using addons with high levels of AA/AF using inspector. I run LOD 6.5 at times, with NGX, FSDT KLAX with NO ai traffic and it's difficult to get even 20 when in heavy weather... In addition to FSX... I tried BF3 with stock cpu vs my current 4.4GHz OC and it was much much smoother in game. | My Liveries | FAA ZMP | PPL ASEL | | Windows 11 | MSI Z690 Tomahawk | 12700K 4.7GHz | MSI RTX 4080 | 64GB 6000 MHz DDR5 | 500GB Samsung 860 Evo SSD | 2x 2TB Samsung 970 Evo M.2 | EVGA 850W Gold | Corsair 5000X | HP G2 (VR) / LG 27" 1440p |
May 11, 201214 yr Commercial Member HT is a no-no with FSX. Get a Corsair H100 and try for 5ghz. Intel recommends a max core voltage setting of 1.6 with the 2600 but 1.5 should be sufficient. FSX comes into its own at 5ghz +. Cheers jja Jim Allen[email protected]SkyPilot Software home of FSXAssist / P3DAssist

Why is HT a big no no with FSX? From everything I've read there is nothing to suggest HT hurts FSX performance, especially if you have the correct affinity setting in FSX.cfg. I know that turning off HT will let you shoot for higher overclocks at less voltage, but can you qualify why HT is a no no for FSX? If this truly is the case then I'll have to think about turning it off. -Anthony Young- "For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return." - Leonardo da Vinci

You will see no boost nor any problems running ht on, but your cpu will produce more heat and lower the chanced of oc. As long ad you don't do it, it doesn't matter, keep ht on, and correct am.

Sent from my iPhone using Tapatalk Word Not Allowed, thanks for confirming my understanding. I may just have to play around with my overclock when I get the time and see what sort of temps/voltages I can get with HT off. For anyone that's interested, I found the following thread which has an explanation of what VID is, it cleared up my understanding of it: http://forums.anandtech.com/showthread.php?t=2188628 Correct me if I'm wrong but essentially VID is a pre-programmed voltage the CPU is telling BIOS it needs at the particular clockspeed/powerstate, but Vcore is the voltage actually being supplied. Atleast that's mt simple interpretation. -Anthony Young- "For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return." - Leonardo da Vinci
May 15, 201214 yr Author Well it's official, I now have the overclock bug and am going to do some testing and get some settings for both 4.8Ghz and 5.0Ghz with HT turned off. From there I'll try running FSX Mark 11 to compare the results at different settings and work out what works best and within CPU temp limits and go from there. At the moment my PC is at home running Prime 95 Blend at 5.0Ghz. As far as temps go, in IBT temp maxed out at 81*C but so far max temp in Prime 95 was 77*C. Now just to wait until 24Hrs is up and I'll deem it stable. I did a quick test at 4.8Ghz HT Off and in IBT my max temps did drop about 10-12*C compared to when I was running with HT On which was to be expected, but I hadn't run Prime 95 over an extended period so I don't know if it was stable. I'll report back on my results once done, then I'll actually start doing some more flying!! lol My Saitek yoke/throttle shipped yesterday so hopefully it arrives just after I've decided on my perfect FSX config. haha -Anthony Young- "For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return." - Leonardo da Vinci
May 23, 201214 yr Author Well I finally found the time to do an FSXMark11 at my different OC settings and will post them over in the FSXMark11 thread. I was able to get my overclock Prime 95 stable for 24 Hrs with HT off at 4.9Ghz but at 5Ghz I only got through Prime 95 for about 6 Hrs and decided to stop spending time tweaking trying to hit 5Ghz and just accept it as it is! lol Results were pretty reasonable although I was hoping for a couple of frames better than what I got.
