    Your first point: It's going to be hard to get 920 stable at 4.2 GHz. Be thankful you have 4.0. Most people with a 920 have to settle for 3.8 (for a 24/7 folding overclock).

    As for your second point: I don't really know. In general I advise against messing around with priority. I do know that you can get some improvement by installing a RAM disk. Others on this forum have done so and have reported good results.

    I thought 920's were some of the best clocking i7 chips out there? I have seen numerous people get their 920's to 4.4 and what not.

    What's a RAM disk?:eek:

    A RAM disk is like a home made SSD, but their not as fast and are far less stable because the memory is not static, so if you loose power you loose your OS, and whatever else you had installed.

    Also just realized Post # 1,000!

    Note the key words: for a 24/7 folding overclock

    Indeed, it's not unheard of to have an overclock that is stable in 99% of what you do, but when you stress it with things like Folding, and Prime 95, it will BSOD you, a stable overclock and a an overclock that is stable at 24/7 100% load, are two very different creatures.

    I find folding stresses my system more than prime95. Don't push the clocks too far

    There are other limitations as well, like the point where your mobo or PSU will vdroop, and begin to starve CPU of voltage.

    True true, i guess ill leave it at 4.0 then. Not many people are hitting 4.0 stable for folding?

    3.8 seems to be where most end up.

    Dang, i hope my 4.0 clock is stable. I wanna keep it at that 4 number :(

    Anybody have any info on thermally controlled fans? I picked up two san aces at a hardware store a while back and according to the model number they are thermally controlled. It say's they are the high speed fan's but thermally controlled so meaning when the temps go up the fan speeds up and when it's colder the fan will slow down. Is their anyway i can by pass this thermal design? Id rather just run the fan's at full speed if i could on my h50. The intake would run slower than the exhaust cause obviously you blow cool air through a rad and the warm air comes out the other side.

    Stick the thermal probe from the fans on the hottest thing in your PC. You can use HWMonitor or Aida64 (formerly Everest) to find the hottest unit in your PC. On my ASUS mobo (in my sig) it's the northbridge.

    As for overclocking - I can run my i7 930 to 4.2, but I can only run it at 4.0 for -bigadv folding. Even then I had to water cool it with some serious hardware to make it stable.

    The fan's have a internal thermostat :mad: Is their a way i can take this apart and disable the thermostat? Id love to run these fan's wide open on my rad.

    Im at 8% complete on my bigadv unit right now at 4.0ghz and temps right now are like 62-68c on my h50. Do i need to be even cooler to be stable?

    60's is OK. I always ran into instability when I hit 80+C....

    I should be more then fine then. :D

    I've been reading up on my fan's and it looks like they spin 2600rpm, and after the internal thermistor hit's 40C the fan will spin the full 2600rpm. This would work great for the pull fan but not so much for the push fan.

    Does anyone have any ideas on how to get the push fan to read 40C so it will spin the full 2600rpm or a way to disable the thermistor? I don't mind taking the fan's apart and somehow cutting the thermistor if that's what it takes.

    These at 2600rpm push 102CFM. I know it's not amazing but it would be much better then my ultra kaze 2000rpm that does 87cfm and a who knows what yate loon 25mm thickness.

    I have 6 of these (Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Cas...) on my dual pass 420 extreme rad. 4 of them are in a push pull config. the other 2 are just pulling the air across that part of the rad. Them seem to work great I've had NP with keeping my CPU (OC to 4.2GHZ) and (2 480's OC to 850/1700/1850 volts @ 1037). Temps stay around the high 30'sC to low 40'sC on both gpu's. CPU runs in the mid to high 50'sC. everything is in a room that stays a constant 67C 24/7/365. All of it has been folding 24/7 for most of last year.

    Yeah ultra kaze's are good fan's. I have one of the 2000rpm fan's pushing on my h50 right now and a 120x25mm yate pulling. I was just thinking if i could get both of these san ace's running the full 2600rpm on a push pull they would drop temps over my current setup.

    I had an AMD socket A back then, and had just switched from an an AMD slot A. I think I still have that slot A in a box somewhere. So many builds...:toast:
