Intel Core i7-5960X ‘Haswell-E’ overclocked to 6253MHz

A well-known enthusiast has managed to overclock an engineering sample of the yet-unreleased Intel Core i7-5960X microprocessor code-named “Haswell-E” to rather whopping 6.25GHz. While it is hard to make conclusions regarding overclockability of Intel’s upcoming top-of-the-range chip, the early result still seems to be interesting.

TaPaKaH, a well-known overclocker from Russia, has managed to push an engineering sample of the Intel Core i7-5960X processor to 6253.16MHz (up from 3.0/3.50GHz default frequencies), according to a listing at CPU-Z. The result was achieved on a system featuring MicroStar International’s MSI X99 SLI Plus (MS-7885) mainboard and quad-channel DDR4 memory kit. For some reason, the overclocker used a 32-bit Windows XP SP3 operating system, hence, naturally, there were issues with correct recognition of DDR4 memory modules.

In order to boost clock-speed of the Core i7-5960X “Haswell-E” microprocessor to whopping 6.25GHz, the overclocker had to disable six out of eight cores (as well as the Hyper-Threading technology), increase the core voltage (Vcore) to 1.753V and also (presumably) use liquid nitrogen (LN2) cooling.

Even though 6.25GHz clock-rate is a nice result that shows good overclocking potential of the “Haswell-E” in general, it has little practical meaning since only two cores were enabled.

Meanwhile, a member of Coolaler forums has managed to overclock the Core i7-5960X “Haswell-E” microprocessor with all eight cores with HT activated to 4.0GHz with 1.046V Vcore. The overclock was not only validated by CPU-Z, but the chip managed to complete the SuperPi 1M benchmark in 14.555s. Most probably the “Haswell-E” could do even better than that with higher voltage and better cooling

KitGuru Says: It is only one day left before reviews of the Intel Core i7-5960X “Haswell-E” microprocessors are set to hit the web. What we do know already is that the new chips should not only offer rather high performance out-of-the-box (which is expected), but also great overclockability.

  1. What’s the point of overclocking a multicore processor if you disable nearly all the cores?

  2. It’s weird the overlock speeds of the 4790k seems better than the newest processors if that is the case whats the point in the new processors?

  3. https://www.youtube.com/watch?v=Q8f1hsAiy_Y

  4. Do you realize that this is an 8 core 16 thread CPU with 20Mb of L3 Cache vs the 4790k which has 4 cores 8 threads and 8 Mb of L3 …oh and and the 5960 has quad channel DD4 support… there are also pictures of the 5960 at 4.5 Ghz on all 8 cores(and will likely go up to 4.6-5ghz)… so on avg. it has double the performance(on paper)

  5. only 2 cores of this cpu wer ocd

  6. What is the paint of OCing it if you disable 6 cores?

  7. My local store already has the cpu in stock: http://ple.com.au/ViewItem.aspx?InventoryItemID=616107&CategoryID=653

  8. What… what was that?

    I need to sit down.

  9. To me i would like to gain as much as possible and to update as possible as i can and im totally clueless as to what the newest processors are capable of at stock speeds and oc’ed. The 4790k seems capable of 4.7 safe oc’ speed to only gain 0.3 ghz on is alittle meh. Also will people wait for a 880ti

  10. Can we please stop writing articles about pointless LN2 “overclocks”? It’s news worthy when its something real people can use 24/7.

  11. If the CPU allowed multipliers up to 33.0 then how did he break the limit legitimately?

  12. JAJAJA AMD FX 9590 5GHZ VS INTEL CORE I7 5960X
    IS WIN INTEL I7

  13. Intel Core i7-5960X can it be Overclocked to 4.5 GHz without getting too heated while playing gaming for hours?
