ASUS VK246H Black 24" 2ms(GTG) HDMI Widescreen LCD Monitor - Retail

Intel Core i7 920 Nehalem 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920 - Retail

Thermaltake Toughpower W0172RU 850W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply - Retail

Thermaltake Armor Series VA8000BWS Black Aluminum / Steel ATX Full Tower Computer Case - Retail

OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model OCZ3G1600LV6GK - Retail

Two times: EVGA GeForce GTX 280 Super Clocked 1GB GDDR3 512-bit PCIE 2.0 SLI Supported Video Card

EVGA X58 LGA1366 Intel ATX SLI Motherboard

the CPU cooler is the TRUE.

frequency: 190
multiplier: 20
memory: 2:8(leaving me with 1500+ mem speed underclocked by almost 100mhz)
VCORE voltage: 1.4
memory voltage: 1.7

I can post at 4.0GHz but crashes with prime95, if you have overclocking suggestions to hit 4.0 stable I'll try them.

You should get a multiplier of 21 if you turn on 'turbo-boost'. What a ridiculous marketing gimmick! Reminds me of those early 386 machines which had a turbo button. Very Happy

This i7 overclocking is pretty weird. Crappy multipliers for dram leading to no asynchronous memory overclocking, strange relationships between qpi, baseclock, etc. If amd lives up to its promise it might yet regain a share of the enthusiast market.

I'm looking forward to Phenom II. Intel dropped the ball by focusing solely on server/workstation market with Core i7. It's not a crap chip in any way but it's not a particular improvement on C2D-gen chips. With the early report of Phenom II saying 4Ghz on air is a piece of cake it does seem AMD have something that will put them back on the map again. They won't go for the extreme flagship though, a rather sensible strategy seeing as the Intel flagship QX9770 is $1000, a ridiculous price for a slightly higher clocked unlocked CPU.

Doesn't seem to match the i7, but at least a brand new system using one of these should be cheaper than going with an Intel proc.

I know, like I said it's unstable at 4.0

and also most people are getting 4.2 on air with i7, some just 4.0 and others like me can't get to that. So i7 = easy overclock to 4 almost guaranteed that you get 3.8 if not 4. So yeah i7 is very easy to OC

Heh, funny how that particular thread have been linked on various forums last 1-2 days.

I'll wait until the chip has hit retail and seen extensive testing and benchmarking as well as have prices to guide me towards finding the best price/performance chip I can get for a set amount of money. Until the new CPU's are actually available and reviewed there's no way I can make a decision or say which is the best choice.

I have a question, if I may:
I just built an i7 rig myself. I have not been able to find any definite answer on what a safe temperature for these chips are. So, I have not attempted to over clock yet. What temps are you seeing and what have you considered to be "safe"?

That's one kick butt system.

well not sure on the max temps, I've looked for that myself, didn't find anything definite.

I'm seeing 49-50C idle on the first core(highest clock is on that core. And 43-48C on the other cores idle. I've hit 88C running prime95, although that is severe load which you won't get when running the highest end game. I would try not to go beyond 90C on load. But also watch out for the vreg temps, I've seen those hits 92C with prime95 as you have to raise those. Hardware these days can take hot temps. Whether you're willing to run at them is up to you. I personally am planning to use a windows software based overclocking tool and switch between profiles one where I game and one where I don't.

Actually that 'if' is much bigger than I can express there. Very Happy

Hehe. i was panicking when I saw it hitting 78C when i didn't have enough thermal paste on the heat sink during the first application.
I may hold off on over clocking until more data is out there. Hell, its fast enough for me at stock speed right now.
