I would appreciate some recommendations in re guards to up grading the current system listed below. The I7 4930K has a bad I.M.C. (Intel Memory Controller) and needs to be replaced with a I7 4960X.

 

This system is used for P3D v3.5 & FSX. A new I7 4960X rather than building a new LGA 1151 with a I7 6700K?

Current P3D & FSX settings are set very high and both sims run smoothe as silk with complicated aircraft with the I7 4930K at 4.4GHz.      

 

LGA 1151 limited to one GPU installed at 16x. If 2 GPUs are installed 8X. Current system LGA 2011 both GPUs run at 16x. LGA 2011 and LGA 1151 has PCIe 3.0

I7 6700K has 4 Cores compared to the I7 4960X has 6 cores. The I7 4960X has dropped in price. $300.00 from the original $1100.00. Could build a LGA 1151, I7 6700K with DDR4 would cost more than the I7 4960X by 500.00 Plus. I7 6700K with one GTX 780 S.C. would be a down grade? Need to run the second monitor on one GPU.  

 

Current System:

CPU I7 4930K was clocked at 4.5 GHz reduced the O.C. to 4.0 GHz. Bad I.M.C..

Mother Board Asus Rampage lV Black Edition. (Have 2 of these mother boards one new box is still sealed).

16 GBs of 2133 MHz C9-10-11 Have 2 kits 1 box never opened.    

GTX 780 S.C. SLI no. Both run at 16X.

Monitors 3440 x 1440 Ultra Wide and one 1920 x 1080.

 

Thank You & Have a Great day

what memspeed do you run 2133?

 

The Ivy -E have quite nice memcontroller 2666-2800 mhz cl10-11 was normal for both 4930k and 4960x , very small or no difference on the memcontroller of the 4930k and 4960x.

 

Difference between 2 x16 to 2x8 pcie lanes on 780 SLI is very very small or no difference.

 

Keep your system the 4960x not gone give you more than 1-2 % if your lucky, and worse if you get a bad 4960x the same or less

 

4960X With good cooling 4.5-4.6 ghz on CPU and mems 2666 cl10 if you ar lucky.

4930k 4.3-4.5 ghz 2666 c10

Westman thank you for the reply,

 

I7 4960X L2 & L3 Cache 16.5 MB. I7 4930K L2 & L3 Cache 13.5 MB.  You are correct concerning the O.C. Luck of the Lottery.   

SLI Mode No. 2 Monitors Primary 3440 x 1440 Ultra Wide, Second Monitor 1920 x 1080 24 In.

 

The IMC is degrading is normal for a high O.C.. How much they degrade over a period of time is relevant to the quality of the chip, V-Core V & Temps.  Will agree the I7 4960X maybe a 2% Gain Luck of the Lottery could be worse. 

 

Why I am considering a new build. LGA 1151 maybe a LGA 2011-V3 maybe a 8% Gain.

 

I7 4930K new 4.4 Ghz at 1.30v V-Core_4.5 GHz V-Core 1.40v Is average chip.

Current V-Core : 4.4 Ghz 1.375v, 4.5 GHz 1.48v will not clock to 4.5 Ghz V-Core @ 1.45v is to high for 24/7 use.  

Memory: G-Skill 2133 MHz 9-11-10-24 1.65v 

 

Thank You

For P3D you'd just be better off with a high overclocked 6700K / GTX 1080

Agreed, this is my combo and I couldn't be happier. I was able to achieve 4.6 easy on the 6700k, and there is a planned upgrade to the 7700k when available. The 1080gtx has provided a small gain over the 980ti in p3d, and a moderate gain in xp.

IMC degrading is not normal if you not run very high mem speed with high voltage to the memcontroller.

Core degrading is more common .

2133 on a Ivy-E is not much to handle for the IMC.

It was Tre years ago a have a 4960X here some bench with 4960x and a Titan, one odd thing with the Ivy-E is in lot of benches and FSX ( not run P3D that time ) it runs better in dual channel vs quad channel.

First vantage with mems at 2740mhz cl9 second super pi at 3200mhz lose timings but ddr3.

 

Run a heavy overclocked 6700k with fast and tight DDR4 in P3D on a Asus extreme VIII single 1080 Strix today.

Not wroth the upgrade though, minimal incense in performance.

Correct, if I was upgrading I wouldn't have bothered, but it is a new build, zero compromise system.

Fair enough, agree. Apologies, I didn't read the thread thoroughly.
