Dual Cpu Overclock Build Concept, is it Worth it?

Poking around online, I've came up with a fun Pc build design. Now before I get into the details, please don't go and complain how there's no point in dual cpus and games don't utilize all these cores. I play beamng drive and for ever car you spawn, it utilizes a core which easily translates to more cores = more cars (it utilizes as many as you can put out). My i3-4150 cant handle this well. I also do a lot of video editing, photoshop, and plan on expanding into more fields.

Now for details, my concept is based on buying 2x intel xeon x5650, 1366 dual socket motherboard, new psu, and a new case. Im basically designing a whole new build except that i'm transferring over my gtx 970. If everything goes well, I'll try and overclock the blck on the cpus to at least around 3.8ghz, if not more. If I can get all the parts together, itd' roughly be around $500. Now here's the part where everyone will say get an i7, but i want to try something different.

I have a few questions: Can you overclock the blck on any motherboard? If so, could any motherboard handle 2 cpus being overclocked? Is it even possible to get that high with 2? is it worth it?

If you agree with me, can you link me a dual socket motherboard that could handle this and give more advice? That'll be very helpful.
If you are against it, give me logical reasons why you oppose this. Just please don't all spam saying get an i7, be reasonable and helpful.

(also, if i go this route ill be gifting my old computer to my mother since it has everything still there except for a gfx card, which it doesn't need. :) )


 
Solution


An i7 980x or above will do the trick, 6 cores 12 threads and with a decent cooler will hit 4Ghz and in australia are about $100-180 per CPU!!
Good luck

there is many advantages and disadvantages, bryan from techyescity does the same as your doing, you can check out his 2 videos here: https://www.youtube.com/watch?v=RS2dEEn9-dI and here: https://www.youtube.com/watch?v=tony8dGupKA
 
blck over clocks wont get you anywhere. however the xeon x56** are multiplayer unlocked. sadly the only dual socket mobo i know fow that socket that will overclock is the evga sr-2 whitch costs a huge amount of money. the best and cheapest option would be get 2 used xeon e5 2670s and a nice mobo and call it a day

Wow watching those two videos, that build was incredible! them benchmarks were very impressive for stock speeds and relatable since i have a 970. The build would be very hard hitting on my budget, being $200+ more. Also on the blck clocks, im pretty sure a lot of people are able to push the chip i mentioned up above to around 3.8 ghz though.
 


no with a blck overclock its not possible to hit near that. i have a blck oc on my current chips and im lucky to get a +200 mhz clock. the chips will only get that high with a multiplier change

those chips are fast enough combined. overclocking the BCLK also alters the chipset, ram, sata and pcie controllers making things run hotter and possibly killing that component, this is why you dont get to far up

Looking at your answers, I"m able to dig deeper into this topic and learn what i'm missing. So far, i've learned that the 1336 chips are fully clockable but not many boards support this, let alone dual socket. I"m now on debating on the idea of finding a decently priced board that can OC, a high thread count single cpu, and bam!
 


then go with a i7. any xeon after socket 1366 is locked and wont oc and any 1366 chips will not get to a i7 level of preformance overclocked
 


XTacticZ,

I've not ever heard of overclocking dual LGA1366 Xeons as they have locked mutipliers, but I suppose it's possible if the voltage could be boosted. I would worry about stability for working though as dual CPU's have to synchronize all those threads between the two CPU's.

Anyway, if you're after 3.8GHz, it's quite easy, the Xeon X5687 which is 4-core @ 3.6 / 3.86GHz, 130W.

Supermicro has many choices in dual Xeon LGA1366 motherboards. The trick is to find the one with the slots you need and whether you really need 388GB of RAM or is 92GB enough,...

Cheers,

this is a bit of misinformation. the xeon x56** series have a unlocked multiplier and can easily overclock to above 4 ghz. the only issue is finding a dual socket mobo that can adjust this. the only one i remember is the evga sr-2. moded super-micro boards have worked as well i believe. the overclocking record was held on a xeon x5698 @6.2ghz for abit

Sorry for the late response on all of this. I understand the new I7's can hit above 4ghz and that's great. But I don't need that much power, I'm just trying to score around atleast 3.8 ghz and squeeze out as many cores I can at a price range below the it-4790k. Thinking back, I don't exactly need a dual cpu setup. I'm just looking for a cpu that can sport atleast 6 cores+ with hyper threading that allows it to be overclocked to around 3.8. I hope that helps you guys venture me on my quest
