The problem with the heat transport between the die and heatspreader is the same with the 4790K. The only solution is to gelid the CPu. If you make that it willbecome 20 °C cooler suddenly.
MSI Z87 G45 Gaming
Th fourd card will scale very bad.
Not really. It works, but the V-ram, which is used even for the SLi, and the higher CPU consumption of the 970, i would recommend not to do that. Better buy 3 GTX 980 this will be something much better, or 4 GTx980. But if you do that, and i think the GTx980 was the best SLI card ever( the EVGA ACX II SC,) buy an asus rampage IX Extreme or P9 x79. With a Sandybridge EP Xeon like the E5-1660@6x 4,6GHZ Quad SLi with 4 980 will work great, 4 970 will work worser but with this mobo6 CPu constallation even 4 EVGA 970 SC will work great.
No because it only drives 16 PCie lanes. For Quad SLi 970 you need 32 PCIe lanes. And even when you use a mobo with plx chips which doubles the PCIe lanes signal( it is together wwith a high input lag). With a MSI Z87X Power or a EVGA z87 classified and 2-3 more mobos you can make quad SLI. But 4770 K @5 GHZ or 4790 K @ 5GHZ. There is no Haswell 1150 CPU wich is powerfull enough to fuel quad SLI, really. And there is a thing with the 970. Because of the partitionated V-Ram ( 3584MB with 224 BIT and 512 MB with 32BIT= address more than 3584-3680MB your V-Ram has a 32 BIT Interface) The thing with the v-ram isn´t so bad because you can adjust the game settings so that you don´t adress more than 3584 Mb and it is ok. But i had 2 MSI GTX 970 4G and it was a great thing, the best thing i have ever had maybe. But when i bought a third 970( with the MSI 970 it wasn´t possible to make triple SLi with using a metall SLI Bridge. The SLI fingers where made that you had to see that you should not make triple sLi with these cards. When i bought an asus strix GTX 970 used it like a bridge between the 2 MSi which worked good mechanicaly but i saw the V-Ram bug the first time, but everywhere.This was the most because of the GTx970 needed more CPU powe for the calibration of the V-Ram. With 2 cards and a strong Hasswell CPu it was ok, but with the third card the CPu became to weak. The triple SLI GTx 970 performance was bad, scalling same like the second card the third. But only in benchmarks, in games the performance of 2 was better. Imagine that with 4x970´s the v-Ram becomes a masssive problem. Triple SLi with 3 980, i had after the 970, was a complete other thing. It worked much better and the CPu wasn´t so overrused. Maybe with a 2011-3 E5-1680 v3 @ 8x4,7GHz or a Core Extreme 5960 x it is something other( and with GTx 970´s from EVGA SLI with 970 ´s work best). But the v-Ram becomes scarce in every way with more than 2 970´s in SLi. With a 4770K @ unrealistic 5GHZ even 4 980 work not realy good. 3x 980 and a 780TI 4physx was a nice thing but it wasn´t validatet by 3 D Mark. I still have a MSI Z87 x POwer.It is a mobo which never was made before and after, so exexissve and uselessss.It has 32 active and passive " Spannungswandlerphasen um die CPU. You never need that. It was one of the most expensive mobos ever and the z97 X Power you couldn´t compare. 150€ it works perfect in original box.
But i like the 4770K more than the 4790K because overlocking is more simple with the 4770K. Over increasing the VCCIN voltage to 2-2,1Volt with offset+ you adjust the corevoltage which is neeedet for the overlocking you want with the open coremultiplikator. Intel speed step deactivated, thermal module deaktivated, overcurrent protection deactivatet, spreead spectrum deactivated you can adjust to 4x4,7-4,8 GHZ. more than 4,8 GHZ isn´t performative anymore and becomes unstable. with my chip.
I upgradet from a FX 8150 to a Xeon E3-1240 v3@4x3,8GHZ and i found the performance increase, even with 4x3,6GHZ massive, insane. My HD 7970 GHZ Crossfire was working the first time. with one card i had more frames than before with 2 and a much better performance everywhere. When i installed the Fx 8150 on my asus crosshair V formula( before a Phenom II 970) i thought it was a bad joke. This poor singlecore performance ridiculous. When i overlocked the FX to 4?8x 4,7GHZ the CPU was..ok. Because i didn´t wanted to downgrade my bios in a blackscreen, like it was when i updated it. No one said that that the bios upgrade ends with a blackscreen and you have to change the CPUs than to have a picture again.
Why did you do that to your computer for? Where you angry with it? even if you were that's no excuse to use such unneeded hate and just plain nastiness, in fact you should be ashamed of yourself! do your parents know what you've done? I bet they don't! You're treading on thin ice Keith, I'd take a long hard good look at yourself in the mirror and ask yourself.... Really? Did i I do that?? Yes Keith, I'm very very sorry but it's not just a dream, it's true, you do have titan x ... :( I'm sorry Keith, i REALLY AM :(
if your video editing software support CUDA or Open CL GPU computing you dont need a very fast processor. . bettar to buy the video card with most cuda cores you can afford.. GPU:s are mutch faster than any cpu.. and way more price effective
Can anybody tell if the i7 4770k handle 4 gtx 970 sc please and answer my questions thank u
Can the i7 4770k handle 4 gtx 970sc just asking
Can the i7 4770k handle 4 gtx 970 sc and my motherboard is a z97-ws quad strength graphic power 4 way motherboard and my power supply 1200w 80p gold just asking
so many people seem to love the 4770k despite the 4790k performing better. i just switched from an amd fx 8150 to the i7 4790k. significant performance increases all around. glad i did it. was it perhaps more worth the money to get a 4770k though? i heard stories about how the 4770k output more heat and had a few other issues but nobody seems to be saying that here.
Your CPU is a Titan X? Lol....
lets hope! i7 4770 and 16g ddr 3 memory, thats all we need
I am so pleased cause i built my gaming pc in September 2013 with a core i7 4770 and i cant believe its still top of the line! I did upgrade my cpu to a titan x last year but thats it for the last 2 1/2 years
I will be getting i7 6700k to replace my i7 4770k, I don't think skylake refresh will be a lot faster than 6700k right now according to this tendency, i7 4770k = 4790k there is literally no difference between them.
I'll be rocking my i7 4770k for probably another year or two. Very good cpu.
here is a good example of a cpu. again you can change any of these parts according to what your budget needs. . The processor I included works with your editing software and is a much better candidate then the i7 4770k (2 more cores and 4 more threads.) and is cheaper by 100 dollars. And if you ever chose to everything is compatible with Edius 8 as well.
I have just realized that both of these processors WILL NOT work with Edius 7 because it is missing ssse3. you will need a processor that has the instruction set "supplementary SSE3". The i7 4770k will work but not 4790 or 4790k.
You can hand pick the best parts for your computers here: this is probably the best website for you to pick out pc parts because it checks if it is compatible with the selected parts. So I suggest a high end 4 core(4770k and the processor needs supplementary SSE3) or an 8 core processor if you have the budget for it. Which ever Processor you pick YOU NEED THE INSTRUCTION SET 'Supplementary SSE3'. Video rendering is strongly cpu based so that should be the focus point for your build. The graphics card dose not matter much, maybe a low end nvidia graphics card (gt530,540,620,630,640 with 2gbs video ram and more is better). The graphics card really depends on if you will be doing other things then rendering and Photoshop like playing games. Motherboards are hard to recommend because it heavily depends what you want from it. So this is where I heavily recommend using pcpartpicker because you can easily compare each motherboard and it's specs. Also pcpartpicker will tell you what brand the motherboards are and the best place to buy them. But I will say for the mother board stick with major brands such as msi gigabyte Asus so on. If you need help with or have questions go to the forum you can get more help there then I can give. Right ram almost forgot. You want a high amount of ram for video editing meaning 32+ just to be safe actually you are probably fine with 32gbs. Don't worry about the brand too much because there is not much difference between them. My personal opinion is go with corsair or gskill(gaming ram but it should not be a problem for for you and it is a REALLY good brand and has low price points.). The frequencies have to be the same as your motherboard allows and cpu but if you use pcpartpicker you won't have to worry about this. Also you want the the highest frequency that you can get even tho it is not much of an improvement it is still noticeable. Also you need a cpu cooler(i suggest an cooler master 212 evo) and you also need a psu or power supply unit and it needs to have enough watts for your system. You can pick out a good one on pcpartpicker and I recommend corsair or evga. So I guess that is it I hope you have fun with your builds and everything goes smoothly.
can u please recommend me the motherboard for the same and other configrations
Thanks for the sir and can u please recommend the other configuration of the computer ( motherboard, RAM, and graphics card) for edittine( Edius 6 or 7). Please recommend the company name also , so that we can purchase easily. Regards Varinder Sharma
