You should be just fine with HT off. Let us know how it goes

I haven't run FSX yet with HT off, but I can tell you that my temps dropped by nearly 13-14C and I can run a much lower vcore (1.475 vs 1.544) and much lower VTT/VCSSA (1.1 vs 1.3). It's unbelievable. I hope the game works as well as it did with HT on.

Oh boy, what started out as a promising thread, is turning into an e-penis match.

 

Haha, someone's gotta trademark that word lol!

Okay, the HT off FSX runs a bit better, my temps are extremely lower and I can use much lower vcore.

 

The problem is, whatever affinity mask I use, I cannot get all cores to be 100%. The first core, core 0 always sits around 2-3%. Core 1 is at 100% constantly. I tried affinity mask 62, 63, and 31.

To clarify, if I run affinitymask 62, core 1 is 100%, rest is 80-90%, core 0 is 2%. If I run affinitymask 31, core 0 is 100%, cores 1-4 are 80-90%, core 5 is 2-3%.

Dear DerStig

Have you red any of the topics I've started? You can improve on load time and texture loading with the help of HT, but not FPS. Do you know that the first assigned thread is the main thread (what produces the FPS) and any activity on the TH'd core sharing with the main thread will cause a drop in FPS? The rest of the assigned cores are texture loaders. They all peak towards 100% every 61 seconds as the lighting is being refreshed. In between the refreshes the load you see on the texture loaders is from...texture loading. So the faster you fly, the more texture loading is needed. FSX also uses a few other threads (around 50% core load) that you can see in task manager (they are very often incorrectly referred to as fibers). These can be scheduled by windows on any of your cores including the core the main thread is on or the HT'd core sharing with the main thread. This is most likely to happen for a while every 61 seconds when the texture loaders peak during the light refresh. That's why we tweak the AffinityMask to avoid the other threads to cannibalize resources from the main thread and thus reducing the FPS.

 

Having all cores constantly at 100% in task manager is never a good sign with FSX. Especially not if you have HT activated. Since only 1 thread in FSX is producing FPS an overclocked i5 IvyBridge will be able to give the same FPS as your excellent build. But you'll have faster load times and can fly faster and still get the sharpest ground textures.

3930k isn't just about 2 extra cores. It has better ISA (Instruction Set Architecture), can work with higher clocked RAM (because can handle higher VTT and VCSSA values) with tighter timings (i.e. I am running 5.0 Ghz on this chip AND 2400 Mhz/9-11-11-31-2 timings), and has a lot more cache at different levels.

 

3930k costs 2.5 times of a i5 2500k, its not 2.5 times faster, I agree. But it is a better processor.

 

Also, can you tell me what affinity mask to use. Right now I'm using 31. My HT is off.

Your chip uses the same ISA as every Intel chip since the original 8086 (instruction set enhancements like SSE and AVX aside). It has benefits over the 2500k as you say, but ISA is not one of them. Your chip actually has an older architecture than the current generation Ivy Bridge chips (3xxx series chips below 3820) which have been measured as being 7% faster than your chip at the same clock speed, all else being equal. Also, newer Ivy Bridge chips support faster memory which leads to additional performance.

Okay, I think the only way you guys will get off my back is if I say this openly:

 

3930k is an overpriced processor that has no benefit whatsoever for FSX. People who buy 3930k for gaming don't know what they are doing. They have a lot of money to waste and they know nothing about computers or technology. Because I'm a rich spoiled person, I'd like to go and waste my money on these tech gadgets for fun and then come here to the forums and show off. I don't know anything about computers and I am wrong, you are right. You and everyone who has turned my thread into a flame war are the perfect gamers/tech people who know the best and know the best strategy to build PCs.

 

Can you please leave me and my thread alone now? Are you happy?

 

I have made this thread for one thing only. It was to share "my" experiences building this computer and how it worked with FSX. Seems like we have a lot of arm chair theorists here like we do in every forum and even such a simple, innocent, and harmless thread, turned into a pissing contest. I'll keep this in mind before I make a similar thread around here.

 

Let me know how that haswell turns out next year.

 

Thanks.

No one's on your back, no one's calling you an idiot. Just providing more info to give a more complete picture.

First thanks for sharing and a very good SB-E Overclock :good:

I was thinking to do a test with a 3930K in FSX most for faster texture loading.

Inrested to test the strap 1.25 1.67 for the mems you seems to be close to max at 2400mhz not many SB-E can do over 2500mhz.

As you know is only Bclk for SB to get higer than 2133 run mine 2255mhz cl8.

This is the part that the 3770K shine i run my mems @2700mhz cl10 or 2800cl11 (max 2974mhz cl11 1.75V) with thigter subtimings its sligtly faster at 2700mhz.

When a went from SB2700k to a 3770k it was most for the memspeed , 7% faster clock for clock and no coldbug.

Now it seems that the 3930K hve the same nasty coldbug and the fact that a need 5.8ghz to have the same fps with faster textureloading

i let the 3770k runs to Haswell is out , i like the rumors of the TDP 84W if thats true a dont need to tune my PhaseChange back to 300W

have it at 220-240W now.

Thanks one more time for sharing your experiences with the SB-E

You fail to see, it's not the 3930K's fault. It's a great processor, it's just that FSX can't take advantage of all of those cores, and everything else.

 

Just enjoy your rig, it's still really great and the best you can have for FSX right now

ROFL!! Your post is funny =D. I'm a fellow 3930k owner as well so everyone here has practically taken a ###### all over my processor too. I always new my PC sucked. Ah well, bring on Haswell!

Hey man, easy. You seem to take things the wrong way here. Who has said you are a riched spoiled person?

I myself seriosly consider getting a 3930K. Just beause of the small benefits the extra cores will bring in FSX. (Thing is, I don't have time/space for my simming at the moment. My current rig is still packed in boxes since I moved house a few months ago and it will remain there until I've got far enough with doing up the house.) It's so annoying that Intel is lagging behind over a generation with the -E series chips. IvyBridge already offer the SingleThreaded advantage over the SandyBridge. And Haswell is soon here.

 

Have you read this topic? I know the pictures have dropped out but you can access them all through links in a post further down.

 

This picture is the most important for the 3930K

Here you can see how you can shorten load times and get faster texture loading under high LOD by the help of more than 3 cores and hyperthreading but at the same time you'll get less FPS. You can't have both unfortunatly. And as you pointed out, enabling HT makes your chip run hotter and thus reducing your potential overclock. FPS, load times and texture loading all scales linearly with clockspeed. If you benchark it properly you'll find that's the case. Anyone saying that a 10% increase in clock gives 30% increase in FPS hasn't benchmarked properly.

 

With the 3930K you can still use the same affinity mask as quad SandyBridge owners do and just enjoy the (assumed small) benefits in FPS of the larger cache and quadchannel memory + faster RAM speeds. But you can also enjoy the faster load times and texture loading the extra cores enables but at a reduced FPS. Something the quad core Sandy+Ivy Bridge owners can't. That comes at a price most people don't find it worth to pay. But you do indeed get something for that extra money. It's just your usage model that will have to decide if it's worth the extra money.

 

When it comes to AM on your 3930K, 62, 61, 59, 55, 47 and 31 should all perform very similar without HT enabling the highest FPS thanks to offloading the other-treads(or incorrectly fibers) but at the same time using the extra cores you have. If you have other aplications running at the same time as FSX it might affect wich one that'll work the best for you so you have to test what's best on your own system. Standard AM=63 will give you even faster load times and texture loading but at the potential risk of not offloading the other-threads at times.

 

You can also use AM14 as many quad owners do. It will give you higher FPS but as I said earlier, you wouldn't make use of your extra cores, just the extra cache and memory bandwidth.

 

Any AM assigning only two cores will allways give you absolute highest FPS. But at huge cost of load times and texture loading.

 

As for having 3930K with HT on I'd assume that AM 4089 would be a good one. 4081 is also a good option. That's the first two I would try myself if/when I got one. Other programs running at the same time as FSX could mess this up however (especially with AM=4089). Using HT together with FSX introduces certain problems but can also give you faster load times and faster texture loading. But unless you are on a dual-core it will never give you higher FPS.

The thing Lars, is that this is FSX and not Super Slew Fest haha. Texture loading is slightly faster with 6 cores, (and load times are definitely much shorter), but at normal gameplay speed, it really makes no noticiable difference .

I don't know, maybe for low (and very, very fast) flying over complex photoscenery
