My voltage is at 1.32V, my max temperatures are 83 on full load with intelburntest (at maximum settings)
You can add 10c for hyperthreading and like 20c for sandybridge to ivy. At that point you are definately heat limited to a large degree and probably wouldnt get past like 4.4ghz. Its on the edge of attainability, but in the end i think even with overclocked haswell i7 it wont be worth it.. game performance is just impacted too much.. FPS loss at least seems to be close to linear with increasing resolution or FPS (at least with one method i tested), so 1920x1080, 60fps would be 5.5x harder than 1280x720, 30fps in terms of performance loss. Thats incredibly scary, sc2 already brings any system to its knees in single threated performance, something like that anchoring your framerates on top of that is not good at all

It's alright to do this, right? (3-pin fan in a 4-pin slot)

Assuming you plugged it in the wrong way (ugh, can't remember which it goes without the diagram), yeah.
Pins are (1) ground, (2) +12V, (3) sense aka tachometer signal aka rpm reader thingy, (4) PWM control signal. The pins for the 3-pin connection are the same, just without the PWM, so they are pin-compatible. No problem just running straight +12V (unless you'd prefer sending less energy so they run slower).
|
It can only be plugged in one way; it has two slots on one side to enforce this. On this particular feed thingy the 3rd pin slot is empty (between the PWM and the other 2 pins). Seems like it's perfectly fine.
|
Oh yeah, durr brain fart. The right thing to say is that they don't let you plug it in the wrong way. Anyway, all these fans need are just some voltage difference between two wires that is great enough to do something useful yet small enough not to cause damage (generally under 13.2V is okay). The rest is extra. No need to worry, unless you've got some high-rpm server fan banshee that's drawing more power that you should be off of one of those headers. Depends on the mobo, but about 1A (so 12W) is a typical limit.
|
They're low RPM ones. Power draw shouldn't be an issue.

how's this build? http://pcpartpicker.com/p/FtLh
the ram comes with the motherboard so it comes to right around 1000$
im going to be playing SC2 mostly occasionally streaming so AMD is out of the question
|
You have two wireless cards? PSU is way overkill. The ram is overpriced by like 20 dollars. If you're only playing sc2 why are you getting a 7950 with 3gigs of ram? Are you playing on three screens at once?
|
7950 is overkill for Starcraft 2
650w is overkill as well, a Rosewill Capstone 450 is significantly better and more than adequate
|
Do someone knows the performance difference between a radeon 4850 1GO and a 7770 1GO ? Is the upgrade worth it ?

Something around like double performance. Maybe HD 7850 is a better idea though, depending on prices.

im going to play other games as well just mostly SC2 so i wanted something pretty decent since its within my budget
didnt mean to put two wireless cards in there
thx for the psu tip as well

95€ for the 7770 and 145€ for the 7850.
|
Nevermind, HD 7770 is fine then. The difference used to be a lot smaller.
edit: on second thought, that ratio is about what it is in the US and other places these days. I'm out of touch and must be thinking of HD 7770 prices from closer to launch.
The performance difference is significant, but now the prices reflect that.
|
Well, if I go from 8go to 4go ram (-20€) and from a nice case to a "good" noname (another -20€) the overall price stay the nearly the same, not sure about the 4go tho, even if my current config has only 2 so it'll be an upgrade still.

What's the diff between the i7-3770 and 3770k? I heard something about overclocking but not too sure..

i7-3770k has unlocked multiplier for overclocking (i7-3770 limited to ~400 MHz overclock; i7-3770k is not).
Also, unimportantly for most people asking, i7-3770k has the superior HD 4000 integrated graphics, as compared to HD 2500 on the i7-3770. It doesn't support vPro or VT-d whereas the normal i7-3770 does, which are virtualization features that you don't care about unless you already know what they are.

question: I am replacing stock fan of i5 3570k in the asrock z-77 pro4-m with a xigmatek gaia sd1283 so I can overclock. do I have to apply thermal paste if it was applied previously? or do I just remove the stock fan, put the new back piece and place the heat sink on the screws on the other side without the paste?

Wipe off the old thermal paste. Then put new stuff on and clamp the fan down.
