Overclocking i7 930

[Guest]

Hello,
I have an:

CPU: i7 930
MOBO: Asus P6TD Delux
RAM: G.Skill Trident DDR3-2000 PC3-16000 6GB (3x2GB)
VIDEO: ASUS Radeon HD 5850 Graphic Card 1GB
HDD: Kingston SSDNow V-Series, 128GB SNV425-S2/128GB
CPU FAN: Corsair Cooling Hydro Series H50 CPU LIQUID COOLER
CASE: CoolerMaster HAF 932
POWER: Corsair hx850
ADDITIONAL FANS: 2 x Asus Passive Water/Heatpipe CPU/Chipset optional fan
1x Video Chip Cooling Fan Heatsink CPU Cooler 3Pin 40x40mm

Just curious how far I can safely push this system when it comes to over clocking. I plan to add another 6gb of ram later. Thank you.

I woulda used DDR3-1600 as I don't think you will get much advantage out of the DDR3-2000 and the 1600 would have let you improve CAS timings from 9 to 6. Options:

Stock 930
133 BCLK x 21 = 2.80 GHz
133 BCLK x 8 Mem Multiplier = 1066 MHz
133 BCLK x 10 Mem Multiplier = 1333 MHz
133 BCLK x 12 Mem Multiplier = 1600 MHz
133 BCLK x 14 Mem Multiplier = 1866 MHz

25% OC
167 BCLK x 21 = 3.50 GHz
167 BCLK x 8 Mem Multiplier = 1333 MHz
167 BCLK x 10 Mem Multiplier = 1670 MHz
167 BCLK x 12 Mem Multiplier = 2000 MHz

50% OC
200 BCLK x 21 = 4.20 GHz
200 BCLK x 8 Mem Multiplier = 1600 MHz
200 BCLK x 10 Mem Multiplier = 2000 MHz

Here's your step by step.

I have already bought the DDR3-2000 so I will just see how that goes. So you think I can push it to 4.2 ghz without issue?

4.2GHz for i7 930 is not a big deal
you're using H50
go for it ~

I guess now the only challenge is to figure out how to do it without frying the motherboard or anything else lol.

No I didnt

So what are the specific setting I need to change to make it 4.2ghz, and also if I can make this i7 930 4.2ghz why didnt intel do it? Surely they know with a better fan or water cooler this can be done. Its not exactly a trade secret.

Nobody knows why Intel chooses the exact cpu speed that they do. There are lots of factors involved, and lots of reasons for Intel to be very conservative with their speeds. If they rated the chips a much faster speeds, more of them would be burned out due to conditions beyond Intel's control and people would be unhappy. This is the beauty of their new turbo mode- it senses when it is OK to overclock the processor and does it.
1. For sure they use a small and inexpensive cpu cooler, which will limit overclocking. They could put in a bigger more expensive one, but then some people would have trouble fitting it in their cases.
2. There is some variation among chips. Some will overclock better than others.
3. There are variations in where the completed PC's operate. Some are in airconditioned buildings, some are in factories, some are in buildings that aren't air conditioned on weekends, IOW some operate in areas that might be pretty hot.
4. Not very many people take care of their computers. The computers and fans get clogged with dust, the fans die and they don't get replaced, the computers get put in places where the ventilation openings are blocked.

You do have a valid point Cadder, I guess amd use to be described as a company that waits for intel to release a cpu and then they just tweak and overclock it and release it as one of their own lol
