Hey jja,

 

Good to see you hereabouts again. Looks like you are going to have another winner. You were the highest 2600K overclocker in the world at one point wern't you- 5.4 or 5.6 Ghz or something like that? Right? Ah, the good old days...

 

Kind regards,

 

Hi old friend - Yea back in the saddle again. Do you still have your 2600k rig? And yes if I will delid the 3770k LOL

 

Cheers

I'll move to P3D when they make it DX10 and make it 64bit so I won't hit OOM.

X79 is a different CPU and sockel. Brings no advantage in FSX though, as the FSX relies on IPC, and there is not real benefit from going 4 -> 6 cores and the quad dram. There have been tests beyond initial 2600K and GTX580, which was a revolution for FSX as a combo, beyond that, hardware has made no advancements when FSX is considered.

 

Well I one time upgraded from an i7-2600k / P67 to an i7-3930 / X79 and there was only about a 3% improvement in overall frame rate in tests I performed in FSX, maybe because of larger L3 cache and more memory bandwidth, not sure. There was also around a 25% reduction in load times and same went for texture loading. However, there was worse stuttering, like 2-second random pauses usually while taxing or on the runway, and I had to tweak the FSX .cfg file to make it acceptable on the X79 system. A few months later I downgraded to an i7-3820, still same micro-pausing without the tweaks in the FSX.cfg file. Then about 4 months later I upgraded my video card from a 1.5GB GTX 580 to a 4GB GTX 680 and this upgrade greatly reduced the stuttering in FSX and got rid of the micro-pausing that was happening in my system without even me tweaking my FSX.cfg file. So it could have been a combination of the SB-E / X79 interacting with the GTX 580 that was causing the micro-pausing or the e 4GB GTX 680 just a smoother performing card for FSX, not sure, but now it's runs well in my X79 system without tweaking the FSX.cfg file. Also when I downgraded from an i7-3930k to an i7-3820, texture loading times increase noticeably, and load times increased noticeably as well, but frame rate was basically the same, maybe because of the similar turbo boost clocks on both chips and how going past 2 cores does not seem to increase the frame rate in FSX. A SB-E will only offer a slight improvement in frame rates over a regular SB system but the 6-core SB-E makes textures and flights load much faster than a 4-core SB or 4-core SB-E system. 2 cores seems to be optimum as far as frame rates are concerned in FSX, the rest of the cores are scheduled to help with just texture loading and flight loading.

 

I recommend an i7-3770k for FSX over a SB-E system. With at least 4 cores at 3 GHz or so, texture loading speed isn't really that bad in FSX and should be more than adequate in normal flight, but frame rates can always use improvements. You also get official PCI-E 3.0 support with Ivy Bridge CPU but not with SB-E or SB, sure there is a hack to enable PCI-E 3.0 for the GTX 600 series card in SB-E systems but it's not guaranteed to be stable since SB-E does not officially support PCI-E 3.0.

Update - got the Corsair case but the rest of the parts will arrive tomorrow so it should be a fun weekend. I had reservations about popping the top (delidding) on the 3770k but after reading multiple threads it seems to be a no brainer.

 

Toms hardware has a nice comparison between an oc'd 2600k @ 4.8ghz and a 3770k @4.5ghz and the results were mirrored except ivy-bridge did better with encoding. I like that.

 

Meaning that if I can get the 3770k up to 4.8ghz I should see some positive bennies in FSX.

 

I have to tell you though that my previous SB build was probably the best machine I ever built next to the old BX (386??) of yesteryear.

 

BTW the biggest advantage to more cores is on a server which has much higher multithreading requirements. FSX would do great on a 2 core machine (if it was fast enough) IMO.

Jim,

 

My new 2700K goes like stink between 5.0 and 5.4 Ghz, depending how my nerves are on any particular day!

 

Kind regards,

I was too contemplating if to try out the 3770K and delid it. Kind of playing with it a bit. But the money is short, so no... Have fun with it, surely amazing performance once delidded!

I have to tell you though that my previous SB build was probably the best machine I ever built next to the old BX (386??) of yesteryear.

 

 

If you delidd, iam sure you have it to 5.0 and if its one of the newer batches that do 5.0 at 1.3v you gone run it @5.1, as you seems to

be one of the old rocksolid Overclockers with experiance.

 

My best build is a System based on a QX6700 ES , back in 05 i had it for 3DMark run LN2 feed 1.9-2.1v @5.1, when it retired 06 a run it in

the SIM and now it works as webb PC. it lives.

 

Cheers Hasse

I'll move to P3D when they make it DX10 and make it 64bit so I won't hit OOM.

 

Is it supposed to be DX10 or DX11?

Update - So far the build is really sweet. I luv the Corsiar case as I can hide all the cabling and so airflow is unhindered. No delid or OC attempts yet but at idle things purr along at 30c. This is my best build ever IMO so I have high hopes for it. The default FSX flight is super fluid even at the default clock. After I establish a baseline and get all or most of the addons installed the fun will start. BTW I bought the RA Legacy which looks to be an awesome addition to the Duke Turbine.

 

The MSI MOBO and UEFI are a work of art. Unfortunately I can't get into a POST Bios cuz the thing boots so fast. Fortunately the MSI UEFI interface is available in Windows so I can make all my BIOS changes there.

 

Cheers

PS - Windows 8 installed in 2 minutes flat and booting into windows takes 2 seconds LOL

Nice to hear jja!

Update - delidded my 3770k and now am running in the 60c range at 4.9ghz and 1.45vcc under load (about a 17c improvement). Going to push for 5ghz now with the extra cooling. The delidding process took about 1/2 hour all told. The hardest part was to gain the confidence that Icould actually do it as when you first start it seems impossible to cut into the silicon. Patience is a virtue I guess. I was mainly worried about slicing up my fingers but blade positioning, starting at the corners and a bit of brute force paid off. Also I was worried about how to glue down the heat sink during the reinstall but you don't need to. Just position it squarely and lock down the CPU holder. Thermaltake Diamond #7 was the thermal compound I used. The plus is that it is non-conducting beside having great thermal properties.. Cheers jja PS it cracks me up that core 2 runs at 8c at idle with the other cores in the low 20s.
