Intel’s Haswell-E family launches later today and the overclocks are already rolling in. Both dudes doing it with the Core i7-5960X must have had fresh changes of pants and underpants and rolls of toilet paper near their benching station, ready for the moment they crapped themselves when something wasn’t working, or the board didn’t boot or the memory went bust. Despite Intel sitting on these chips and the X99 platform for a long time to make sure it was good and ready, it’s still brand new stuff that no-one else has ever submitted scores for. being the first of the benchers for Haswell-E has some perks, with the main one being bragging rights.
The first was a CPU-Z validated overclock under LN2 (liquid nitrogen to the newbs reading this) by TaPaKaH from Russia, with a i7-5960X engineering sample. The chip had all but two cores disabled and the board in use, MSI’s upcoming X99 SLI Plus, had the bus speed increased to 125.06MHz, which is incredibly high for first-generation overclockable hardware. The processor clocked up to 6.2GHz with a 50x multiplier and a shockingly high 1.753v. That chip probably won’t last very long at that voltage but for a first-generation overclock this isn’t bad at all. Netting more than twice the default clock speed is even more impressive, although enthusiasts won’t ever see that with air or water cooling setups.
TaPaKaH benched the system to run SuperPI using Windows XP SP3 32-bit, which was done to see if Windows XP had any eccentricities when using DDR4 memory. While the memory modules weren’t recognised correctly, the system still ran fine.
A member of the Coolaler.com forums who goes by the name of “thyan3” also managed to benchmark his/her system. It was a Core i7-5960X cooled by a Corsair H110 liquid cooler on Gigabyte’s upcoming X99-Gaming G1 WiFi motherboard. G.Skill DDR4-3000 memory was used along with two Geforce GTX Titan Black graphics cards and two 256GB SanDisk Extreme Pro 256GB SSDs in RAID 0.
thyan3 first benched the system at stock settings with the processor turboing to 3.3GHz and temperatures staying between 23°C and 45°C from ambient, which isn’t bad at all. CPUID measured the power usage at 103W under load, although this is still with some throttling taking place to keep the system under the maximum TDP.
An overclock of 4.0GHz on all eight cores was reached at 1.2v and with the board’s bus speed set to 100MHz (the default). This improve the Cinebench scores considerably (1270 to 1508) and SuperPI was calculated at 14.555 seconds after 19 loops. Looking at the time in the taskbar, the overclock took place on the first of August, which would have been around the time that motherboards and processors would have started to ship out to distributors to have a bit of stock available on launch day, where the NDA should lift up later this evening.
Anyone excited to see Haswell-E blow the socks off Intel’s previous best attempts? I sure am, although I could never afford one of these systems personally.
