Additionally, voltage (which increases heat) must be increased [to match the increase in clock].
As heat increases stability decreases.
As voltage is raised [ and here's where i'm having problems with some advice I have read , but can't find a link now] some "guru's" have advised raising the voltage to increase "stability", in the assumption that its the heat CAUSING the instability.
As heat increases stability decreases.
Maybe you can start be defining "stable" .. are all overclockers meaning the same thing?Warning: Spoiler! (Click to show)
Obviously this is a paradox (catch.22)... and like most mysteries, is based upon misinformed expert opinion. I'm not arguing, I'm looking for a community consensus as to the rightness/wrongness of this guys thinking, becasue i'm having some problems with his logic, not defending it.
With the little i've uncovered, I was suprised to learn the low voltage on my CPU was not a bad thing ... it IS stable (i5-3570k oc 4.5ghz @ 1.08v running prime95 in the low 50's c). But my wattage is low also (45w) ... (becasue my voltage is low?... which is low,because my temps are low?)
I'm just trying to wrap my head around these variables. I've looked at the "guides" ... mostly ongoing conversations, back-slapping and a stream of acronyms I have to google... and nothing for my setup hardware/bios. I've looked at utube ... mostly shallow reviews or Intel marketing fluff **. Went to Intel... all waving hands, smoke & mirrors ... ( ***!! did a rabbit just pop out of his hat?***)
Below is a link to a review of *Intel Visual Bios ... it has screenshots of every options page, maybe you can suggest some particular settings for boosting performance?
Below is a link to a utube video review of same.
Below are "Intel Engineer's Dave & Greg"... whom I'd like to punch in the head.
Intel Z77GA-70K (Intel Visual Bios*)
Corsair H50 Cooler (rated for 130+ tdp CPU's ... i'm pushing just a fraction ... pump speed was single biggest cooling factor in my tests, fans second, case flow 3rd)
Corsair TX 850 (kicks in the teeth of the TX 750 ... much heavier, lower % system load means less heat/fan/noise)
Corsair Vengence LP 1600 (4x4GB)
EVGA GTX 660 TI 3GB OC ( my gtx 260 was ok... now i'll see what i was missing)
Seagate 1TB sata II (the weaklink ... have 4- 2tb sataIII but they are full & I blew my load on the build.. had this new in box)
Intel 520 120GB [Smart Response & Readyboost Caches] ( 5 sec boots... after post... 3 sec shutdown... responsive,feels like some windows open before i even clicked)
Antec 902 Mid-tower
Plantronics Gamecon780 Headset (nice 7.1surround, cheap online @ $47... valve has custom logo'd versions@ $78)
Thermaltake BlacX dual esata (works well , but machine won't boot when it's turned on... maybe a bios boot setting pointing at the esata, haven't looked into it, or, whether the mobo has port doubling)
Once upon a time I worked for the Apple reseller in Portland, Oregon. Also, Egghead.com (Vancouver,WA), phonesales, when they went under in 2001.
I love my toys.... I've got some old dells (Optiplex GX250-P4, Optiplex 745's-755's - c2d's), systemax c2d, (2) hp xw4400's ( I'd like to upgrades the 1.8ghz c2d's to quadcores), newer amd laptop, Apple G3,G4, (8) G5 Xserves & a tower full of network gear ... (5) 23" 'project' monitors that need new caps....
All of my Intel based machines (exept the P4 .. mx440?) run Nvida GTX 260's, 250 or 240's. After 20 years of ATI's inferior Apple vga's and worthless drivers... they lost me FOR-EVA! Don't belive? I have a dozen of them... fricken 8mb vram in 2000!!??!!. They were the reason you couln't game on the mac. Shiiii... I have equipment older than many of you
( I threw out my lcIII, finally)

Ok its's stable and maybe i haven't been clear enough... i'm looking for a liitle help here.
Unmitigated heat isn't an isolated incident without consequence to the system... thermal shutdown lies at the end of that road, no? (ie, instability)
Maybe you can start be defining "stable" .. are all overclockers meaning the same thing?
Overclocking! OK... now were are getting somewhere... using what you know of overclocking... and using the information i provided, about my bios, in my rambling monolouge above... can you give me REAL practical numbers i can start plugging in? Am I bound by my bios limitations? What are they?
Your assertion that H50 is mediocre is not proven by my results. I'm reading about others running 3570k and unable to make it stable or crash free @ 4.3ghz @ 1.25 volts. I can't get it to crash or even warm up. Tuning my fans got me 7c... forcing the mobo to runs the pump at 1400 rpm instead of the 823 rpm , gave me 10c ... neg pressure in the case... another 3c. I was running , as you say in the 70's... now 50's when oc's and running prime95. YMMV
My guess is Intel is flipping a switch behind the curtain on my settings in the auto overclock... It says full load , but not registering any real overclock. As I don't know enough to ask inteligent questions, perhaps... you can just look over the bios and give me the settings, instead of giving me a hard time, k?
Note: I was just gaming in stock mode (a :source game) ... I left the game running and checked some stats .. 23c on the processors 41c max... 17% load ... 2200ghz .. Ok.. maybe it didn't need any more power to push out 125-250 fps .. but still , how can i kick this thing in the @ss? how much power saving does a high end gaming chip need?
chat on steam?
OK lets step back and take a breath here ... OPFORWARRIOR you remind me way back when I 1st discovered overclocking (P4 days
) ... your a bright guy and have a very analitical/logical way of approaching tasks, and trust me it will be hard to learn/absorb all the nuances of overclocking in just a few days, (which is your nature
) even with the now oversimplisict nature of the 1155 platform!
Like I said earlier I'm not familiar with the Intel bios' and it's OC nature. But I took a look at your Intel bios links and that's one nice looking/comprehensive bios! I think I mislead you earlier when I said to start clocking through the bios ... I should've said start MANUALLY clocking through the bios instead of using the "presets" or what we use to refer to as "software" clocking ... for starters do exactly what the guy did in the "youtube" video .... (oversimplified) manually
setting the cpu multiplier to 48 (maybe start at 4.6?), disable speedstep, disable some or all of your power saving features, BUT also manually set your CPU vCore to what your max voltage is now (or bump it to 1.30-1.35v). I like to use SuperPI (1m/8m) as a quick initial stability test. When you get the hang (no pun
) of it you will be able to "sense" instability and get an "error out" before the annoying BSOD and CMOS reset. Raise your voltage (watch load temps!) or lower your clock when this happens, until your stable???? Wow did you open a can of worms with this statement ... Quote:Maybe you can start be defining "stable" .. are all overclockers meaning the same thing?
NO they are not ... all depends on your "mission statement" ... is it a NASA critical "simulator" / a folding rig / or everyday gaming/general use machine? .... for me 8hrs of P95 is my general standard, and depending on the "use" and overclock I'll get away with 2hrs of Prime (20min of custom 1344FFT / 1792FFT's) 98% of the time
... you'll know what I mean depending on how much time you put into it or how many platforms you overclock with in the future ...
What to do next is a matter of taste ... keep bumping the multi and/or vCore OR start with a higher vCore (1.45v?) to find your desired multi and work vCore backwards ... if you can get to a 4.8 - 5.0GHz overclock without crashing your rig I'll personally send you a "Cookie"!
Hmmmm we didn't even get to overclocking your RAM
I could write pages on this (hence OC links) and We are getting pretty far off topic for this thread ... So I would also suggest starting your own thread [HERE]
... your only challenge there is weeding out the "mis-information" and there will be some
, but that is half the fun of sites like OCN
for me in the 1st place

I'm not after mad max clocks, so I think I'm very happy for now. There was a bit of instability when playing some games, but I'm running offset voltage +0.005, and I had all C states enabled. I left C1E enabled (as recommended by many ppl here and other tech forums it seems), and turned off C3, C6, and Package C. Haven't had any issues with crashes or random behavior since. I thought it may have been the CPU getting random drops in voltage, when checking CPU-Z the overclocked frequency fluctuates a lot, from max 4.6ghz to around 2.0ghz to 1.6ghz (minimum). Average voltage and maximum have remained unchanged, still not seeing anything higher than 1.238vcore. Once, I saw 1.24 which was kind of weird. Anyway now I turned off most C states I don't get weird fluctuations in my frequency when the CPU is actually under load (even for a lighweight program or game).
As for my ambients they are usually around 21c - 23c, sometimes lower or higher depending on if I'm feeling too cold.
But I appreciate your input and after doing a lot of reading over the past few days, it seems that although my chip is not GREAT it is pretty good for being an Ivy, I'm just happy that the voltage isn't too much. I remember when first trying the auto tuning feature on my bios, and HWMonitor was showing 1.48v, scared the **** out of me and I immediately shut off my computer after a minute or so
... IMO your observations are "Right On"! ... for fun watch the "frequency" variations in "Real Temp" (w/high refresh) ...

Thanks!, really looking forward to using the H60.
If I'm not mistaken doesn't the 2nd Gen H60 come with this fan already ... [HERE]
In any event I'd set it up stock and start from there ... how high of an OC do you want? You've got a nice case (hence good circulation) you may be surprised how well it performs at stock depending on your overclock and ambients, and it will not hurt to experiment with your case fan in the pull position

Or are this just the SP120's from corsair?
Again depends on overclocks, 24/7 use etc, BUT the H100i stock fans have proven to be very efficient with both static pressure and noise levels. Most of the H100 (note: the H100i seems to be even more efficient) users have found a push/pull system is "Overkill" for the average overclock/ambients with solid case ventilation, which you'll easily achieve with the 650D
Trust me or search H100 push/pull within this thread ... like [HERE]
But if you find the need or just want push/pull ... you can't go wrong just matching the SP120's that come w/the H100i. see comments above
