i can overclock with this B85 board of mine??
yeah but i only have a 4 pin cpu header. that won't do it for an overclock. hmm maybe for a pentium? it would be enough? i'd have to buy a new CPU though

The first one looked like this: http://uk.gigabyte.com/fileupload/product/2/4144/5646_big.jpg So it didn't have that 8pin power connector originally. It might not be terribly important, especially with that two-core CPU being less power hungry? | ||

still though, thanks for the reassurance i might just buy a pentium to overclock it. so those are the extra features that make B85 premium over H81. see my post previous page on how I didn't get it. | ||

Though, just by using common sense, I think you could get a reasonable overclock on a B85. It's only two cores which require overclocking, so less power is needed so less heat produced. I guess.. As long as you don't try to overclock anything more than a Pentium I think it should be all right, but real reviews need to released. Yep, that's a heat-sink. Despite that weird 4pin CPU power connector used on the original design, the board's VRM isn't bad at all, instead seems super good. I put 1.365 V into my CPU, and the VRM temperature slowly works its way up to 60 C or so when stressing, but not really more than that. Meanwhile, the temperature limit in the BIOS is set to 135 C by default, so that's pretty reassuring.  So if they originally decided to use a 4pin connector for a strong board like this, that particular design decision might also be totally fine on your B85 for the Pentium? There are these for the heat-sink issue: http://www.enzotechnology.com/mos-c1.htm Those are a bit expensive. There might be something similar out of aluminium for much less. | ||

Not sure where the VRMs are though. ![[image loading]](http://i.imgur.com/BwzjKl2.png) | ||

Here's what they are: http://en.wikipedia.org/wiki/MOSFET I'd be afraid that there's simply not enough of those. You could maybe try to touch them now with your current CPU and see if they are hot and can hurt you? The cooler is perhaps in the way? | ||

Here's a picture of the screen I get. http://i.imgur.com/4TQxHxF.jpg The manual says that I should see a Logo screen containing the words GIGABYTE etc. and then the BIOS interface. Is something wrong with the CPU or the motherboard? | ||

I was under the assumption that it was supposed to boot straight to the BIOS (which is what my motherboard manual said). It's asking me to "Reboot and Select proper Boot device".

You have to repeatedly press DEL during the boot process to enter BIOS, might be a different key like F10 or F12 for your board but it's usually DEL on most boards. | ||

It's working! :D And just a last quick question. What's a comfortable temperature for the CPU to be at? It says that mine is sitting around 54 C. | ||

It says that mine is sitting around 54 C. 54c is kinda hot for bios Haswell with all power states (manually enabled c-states, EIST, as well as balanced power plan in windows) consumes very little power so it idles low, at 800mhz and low voltage on stock cooler i'd expect temps in high 20's to low 30's with 20c room and "ok" cooling, but i don't really know the stock cooler. | ||

The temp gap is maybe worth half a delid. Nothing else significant seems different(?) ^That's pretty much exactly what i expected and said. A temp drop of only like 3-5c would be small and not really worth making a big deal over, yet getting solder/delid temps without using solder/delid seemed unlikely to me. OC notably higher at a given voltage, was never guaranteed, just a lot of people hoped for it. Doesn't really seem the case at all, same silicon same stepping same clocking etc, just at 70c instead of 80c. I was going to check my bios temps as well as try 4.7 voltages a bit more long term, but i can't actually get screen display before windows starts to load, if i hit delete before then, the screen that bios usually comes up on just sits there, on like it's recieving a signal, with backlight on but not displaying anything. I'm gonna try to fix that now~ Fixed it, messed around for ages and i had to reset cmos. My bios temp was 31c, after a few mins in OS my min is 26c (~20c room) ^but that was stock voltage in the bios on a silver arrow, and the OS is in power states, though with 1.395vcore@load set. | ||

HD7950 3GB, i5 4570, AsRock H87 Pro4, Corsair 8GB 1600, Capstone 450 When playing LoL, sometimes I'll freeze and the screen will turn black for a second; usually not annoying but it can make or break some games. Sometimes, the screen will turn black and the game will crash. I usually see 100% CPU usage in task manager when this happens so it may not be entirely my GPU's fault. In order to fixed this, I went into CCC and downclocked from the factory OC of 925 Mhz down to 850. However, my brother started crashing in Witcher 2. I've run a few benchmarks such as Valley and I never seem to have issues there, with temps never going above 65C-70c. As of now, I've reset to factory OC of 925 Mhz using CCC. I also have Sapphire's TriXX but unless things get worse, I'm gonna leave things as they are. Any help as to what I should do will be appreciated! | ||
