Overclocking i7-950 to 3.8 GHz

I haven't messed with my desktop much with overclocking lately. Mainly because I use my laptop more than anything, but things are such that I get to use my desktop regularly now! When I installed the Corsair H80 closed-loop liquid CPU cooler I thought I'd get good temps, and I did because my CPU idled ~10°C above ambient room temperature around 55°C at 100% with Intel BurnTest and the same with small tft prime95. After OC'ing today to 3.8 with hyperthreading, speedstep, and NX bit enabled. The PC used to have 12 GiB of 1600 MHz DDR3, but for the simplicity of overclocking I went down to 6 GiB (I also don't use much RAM anymore for the negligible gain in 99% of tasks).
Stable as fuck up to this point with automatic voltages, but the motherboard always overshoots a LOT and that wastes electricity, generates heat, and shortens hardware life. So I'm now slowly notching down my VCORE while maintaining 3.8 and then once all of that is done I'm going to go for 4, but I need the voltages for reference because heat gets close to max at 4 GHz (with some features enabled... but honestly hyperthreading needs benchmarks for OC's).

the thing i like about these i7's is they automatically overclock a core when one of the other cores is not in use (or has a little overhead left). they also clock down way b4 they reach dangerous temps. they are truly a dream come true for over clockers, but u really dont even have to.
edit: once u find some really stable settings, u mind sharing them?

Ya I can give you my settings. The Sabertooth x58 makes OC'ing really fucking easy for a moderate overclock like mine. You only need to change the bclck when you first go to manual settings, and leave most shit set to auto. The problem is that the BIOS will overshoot what you REALLY need for voltages. At 3.8 with auto VCORE(all voltages except DRAM BUS) I was hitting 80C with Intel BurnTest. I think the voltage was like 1.3 or some shit... I was able to go to 1.25 so far w/ no problems except having to tweak QPI and some other voltages because of VCORE lowering. All of the tweaking for lowest stable voltages is so I can get to 4+ GHz.

nice mobo choice, i got a p6t a few years ago, the sabertooth was still retard prices. i had mine clocked at 3.8 for a minute, but i only use my i7 w/ 12 gigs of ram for web browsing *cough pirating cough* so in the end i put it back to stock.

I was going to get a Gene/Formula, but the functionality vs cost just didn't seem worth it... I'm kicking myself now though because the placement of the 2x PCIE 2.0 16x slots are spaced such that my 6970's are ridiculously close so the top/first GPU is running warm. I have to use a custom profile in Sapphire Trixx. Luckily the HAF X tower has a nice shroud for nVidia certified cooling or whatever... It just screws into the chassis on the back side of the hdd bays. It fits nicely over the 6970's so I put a Scythe Ultra Kaze 120x38(mm) 3000RPM fan in there that pushes 133 CFM. I'm shocked my system runs stable with all the power consumption having an 850 watt PSU, but getting 80+ Gold certified PSU's is well worth the money! Every fan header on my mobo is used except the one +5v header. It's so retarded really... by October I plan on getting the water cooling going.
230mm Front/LED Intake 200mm Side-Panel Intake 2x 200mm Top(where rad(s) would go) 120x38mm GPU Duct 2x 120mm Corsair 2000+ RPM in Push/Pull via Corsair H80 (not worth it... get an XSPC RASA)
All fans run at full speed so that's a decent amount of power. The noise sucks ass as well... the H80 is loud, I can't hear the Ultra Kaze from outside the case, but worst of all are the 6970's. It makes no sense that these cards will have the fans barely spinning at 70-80C and at 80% fan speed they sound like fucking centrifugal fans.
Later today I'm putting a multi-meter to my top two 200mm molex connectors because the large fans are rated at high CFM's, are quite, but you can barely feel the air they push so I want to make sure they're getting enough juice. My temps should be better with the H80, but instead of upgrading the factory fans I'm gonna eBay it with a 6 GiB DDR3-1600 set and other stuff I have laying around to help with the water cooling. I'm just going to make my own reservoir since you can buy Lexan and other shit at Home Depot. Maybe I'll luck out and find a used bridged block for the GPU's...
The video cards also block the fucking southbridge and it gets pretty warm. When I start the water cooling I'm going to remove the heatsink and replace it with Shin-Etsu TIM.

that is why i got a full atx tower. it has 2 huge fans on the side, a rear exhaust fan and room for a v8 cooler on the cpu. it also gives me plenty of room for the 5tb of hdd i have in it and the 2 plextor burners.

Yea I think the HAF X is probably one of the best towers I've purchased/seen in a while... for mass production anyways. I've spent a lot of time looking at acrylic cases and guides on doing it, and I want to do one with Lexan... don't ask why I just do, because if my kid hits it with a baseball bat or something it will just laugh at her.
Just a couple of hours ago I ordered some Shin-Etsu for the motherboard heatsinks, and I was super psyched to get the Indigo Xtreme for my cpu. If you haven't seen the Indigo Xtreme you should read about the product first and then the reviews/benchmarks... the shit is INSANE. I wanted to start getting my water hardware together so I bought these
Cooljag Everflow 110cfm 120x25mm
I'm going to use them with the H80 with one of the two Indigo setups.

something else important i forgot to mention about i7's. when they make them, they just make a big wafer of them and chop it up. then they stress test each individual chip looking for the top performers (goes fastest w/ least heat). they only make so many 3.33ghz's then when that quota fill they fill the quota for the next speed down. in theory, u can POSSIBLY get a 920 that actually passed the 3.33 test. this is another reason why i7's have been so popular on the oc scene.

hey are asusp4p800 motherboards easy to overclock? I'm using an intel dual core at about 2.4 ghz and was wondering if I could clock higher.
that i7 is pretty nice by itself already. I'm pretty reluctant to use water cooling. one leak and your board will probably fry. anyway asusp4p800 motherboards if you remember are fairly standard boards, they have been replaced recently, but were the main boards used a few years ago in just about any low end-mid end computer using an asus board. the board I have doesn't have a pciex16 slot, which sucks, so it is an older model. can only handle 4 gigs ram etc. but if I can overclock my dual core 2.4 ghz to 2.8 ghz I'd be pretty happy 
if not, then don't worry about it

Yea, it makes you wonder what the variations are between the chips. I'm sure over the years there have been "lucky" CPU's that had less impurities and mfg. flaws, statistically speaking.
There are a few threads I've browsed through when learning about OC'ing the i-series' that made it obvious there are definitely bad batches. Some poor bastards just hit a wall, well below extreme overclocks, and can't do shit no matter what they try. 
For the time being I stopped optimizing my overclock because an opportunity presented itself! I sell old college textbooks at this time of year and sold like $300 worth in less than 3 hours of all the scheduled auctions starting. When I put the books up with a "Buy It Now" price I always go higher than I'd expect to get, and so it shocked me they sold right away. 
Anyways, I just happened to check eBay for the liquid cooling shit I wanted and a seller had the CPU block and reservoir/pump combo listed with only a day left on the auction(this time yesterday). It was two auctions but I asked him for better, detailed pictures and the components are basically brand new. He bought them and changed his mind... at least the auction said that.
I got this: EK Supreme HF Rev 2

MCP-355 Pump (Laing DDC) with XSPC reservoir.

All of that for $110! Off to a great start. I wanna sell my Corsair H80 soon before it's outdated so I have more $ for tubes and shit.

I read a forum post a while back comparing the CM V8 to the Noctua NH-D14. Prior to purchasing the H80 my plan was to get the NH-D14 because it performs as well as the closed-loop systems and is the best air HSF I've seen. The colors Noctua uses for the fans is so fucking ugly though...
Anyways, the guy in the thread had an i7-920 @ ~4 GHz with the V8 and got to 4.2 with HyperThreading using the NH-D14 and his temps were around 70C I believe.

One other thing you can try using to increase the efficiency of your heatsink/fan is Indigo Xtreme.
http://www.indigo-xtreme.com/
I bought a kit of it, but at $10 per application I'm holding on to it until I have all the shit I need. If you read any articles from Skinnee, a respected tester for cooling devices, you'll see the Indigo is fucking amazing shit.

It's very fucking annoying to install since your cpu needs to be horizontal... idk how water loops easily get reflow, which is probably why many people doing liquid cooling use Shin-Etsu or something. Anyways, it uses a phase change metal alloy that comes as a thick half square on the engineered interface material. You have to let the CPU run at 100% load to hit close to 100 C, at which point the CPU automatically powers down a bit to avoid thermal damage, and at that temp the alloy basically melts and flows into/over the gap between the heatsink and CPU. So if you install everything perfectly the reflow should essentially cause the alloy to create a highly conductive interface that has very, very little error or empty coverage. I've wanted to install the fucker for a month now but aside from adding water cooling I also want to sleeve my PSU cables.
The only con for Indigo Xtreme is that some of the best performing air-cooled heatsinks passively dissipate heat so well that it's hard to get reflow... it takes a lot longer for the Noctua I mentioned previously.
