Overclock i7 875K on Asus P7P55D-E Deluxe

Postposted on Thu Oct 21, 2010 2:06 pm

Hello guys.

I'm looking forward to OC my new computer and i come here once again to ask for your advices. My first and only OC is with my E8400 @ 3.6 with Gigabyte GA-EP43-DS3L but it was 2 years ago. I was looking to buy a new Gigabyte board for my system but almost every P55 board got problems with USB3 or SATA3 and this time i chose Asus and i hope i will not regret my decision.

The Turbo mode is activated and i didn't find the option to disable it on the Bios... I thought it was the [Turbo Profile] but there are no other options there...

My goal is to achieve 4Ghz stable enough to stay up for 24/7 just changing the multiplier and the memory @ 2000Mhz

BIOS images below. If there are any other images necessary just tell me.

New rig:

Core i7 875k @ 2.93Ghz (CoolerMaster V8 + Artic Silver 5)
Asus P7P55D-E Deluxe @ BIOS 1301
4GB G.Skill DDR3 2200Mhz (F3-17600CL7D-4GBPIS)
Gigabyte GT 240
SSD OCZ Vertex 2 120gb
PSU XFX 750 Black Edition Modular
Case CM HAF 932
UPS APC BR1500

Any advice will be very helpful. Thanks.

My Best Regards,
Queiroz

I just started the OC test and i have set 24 x 167mhz and the memory 2004Mhz (2:12)

Vcore: 1.30
IMC: 1.30
PCH: 1.05
PLL: 1.80
DIMM: 1.65

I leave turned on just the prefetcher, prefetch, All cores and HT.

I saved and rebooted the machine. The boot went fine and as soon the windows booted i opened CPU-Z and it shows 4019Mhz on the Core Speed and 1004Mhz (2:12) on the DRAM Frequency and it's normal at the moment but the big problem is the temperatures because it's 48ºC idle and i opened RealTemp and LinX (memory run 3 times) and as soon as i started the test the temperatures went very high 92ºC and i got worried and stopped the test because i believe this is beyond normal, right? What should i do? Maybe Thermal compound application was not correct? Just one dot in the center of the CPU.

Yeah those temps are too high. My i7 875k at 4ghz idles at like 25-28 and load is mid 60s. I don't like your thermal compound application. I usually use a card to spread it evenly on the chip then place the heatsink on top. You can also use the single line in themiddle and circular rotation of the heatsink.

How does that "Intel(R) TurboMode Tech" sound like to you? ;)

The Model M is not for the faint of heart. You either like them or hate them.
