Your right Von they are right there under the HEAT SINKS lol mainly because they get hot sillies.

that would make sense since they are supposed to have to do with regulating power to the CPU right? hahaha. Like I said I Know ALMOST nothing about vrms.

That other piece looks like a heatsink too though.

what you pointed out, is where the Z77 chipset is smile.gif
needs cooling too..lol
i remember the northbridge on my gigabyte 990fx ud3 mobo was always very hot,
put a little fan on it later..

Ahh, thats why this site is great most of what I know other than the basics of Pc's i've learned from here.

I have a shot those heatsinks with an IR gun on the surface. Never had anything past 85 degrees fahrenheit.

I will try it while priming small ffts for a little bit

still thinking about that link you gave chronicfx,
the thread starter also says,


"http://www.gigabyte.com/microsite/68/tech_090814_p55_u-24.htm
This link shows a picture clearly the issue I am having possibly causing my BSOD 0x124"

the link goes to a GigaByte pic, showing 24 Phase Power VRM Design,
where sin later says, its not how many you have, but the quality..
its like he thinks, that he doesnt have enough of them

but he blames his BSOD 0x124 on overheating vrm's,
in my code list, this 0x124 means you have to up vcore some more,

the next poster in the thread says,
"Are the prime95 runs are failing on the same FFT size or at a random point?
As VRMs can fully function at high temperatures, it could also simply be a lack of CPU voltage."

so they can take some heat, not sure what their max temps are tho, 100-110C ? smile.gif
k, done thinking about it ..lol i hope wink.gif


found this too,

"n recent review of Z75 pro3 became clear that 2500K can run at maximum 4400Mhz offset -0.025V without throttling.

I suggest you do the same. Z77 Xtreme4 also throttled. it has to do with VRM temperature threshold set too low in early bioses or in hardware.

Less VRM phases means lower efficiency and more heat and with heat efficiency drops even more. 4+1 VRM compared to 8+2.

The 4 pin connector is posing the risk of melting the connector with 150 watt cpu under the Linpack load.

So precautions are set in place by asrock... No bios update should or could fix what lacks in hardware.

1155 cpus are compatible but really this Z77/Z75 is meant for Ivy bridge a cpu < 100 watts overclocked.

example:

lets take the base minimum overclock to be 2500K 1.2V 4.0Ghz that results around 100 watts under linpack11 or prime95 v27

So 4.4Ghz how much? you reckon?

1.32 volts needed for 4.4Ghz means you have 10% increase in voltage and 10% increase in clock.

power dissipated by a circuit increases with the square of the voltage applied.

How much? 100*(1.1*1.1)*1.1 results 33% increase in power consumption ~ 135 watts.

and so on. 20% overclock with 20% increase of voltage gives 100*(1.2*1.2)*1.2 ~ 175 watts.

take it to 5Ghz and consumption doubles and motherboard burns.. hope the +1Ghz was worth it.

Asrock should send you a 8+2 VRM motherboard instead. not a bios fix since yours is only able of 135 watts and you seem to be willing a little more than that. the 4500Mhz mark."


so, i guess the thread starter was right when he said,
"I cannot touch them because they are too hot. Apparently these are light for a i5-2500k."

hes right about that, like the info i posted above mentioned too,
on further search, someone else mentioned, they are made for "mild" oc's, about 4.5ghz,


i so hate myself sometimes, when i have a Q. in my head, i need to find a answer ..lol,
sorry if i flood the thread with this..

Asrock extreme4 is an 8+4 design. Also my 3570k overclocked uses about 191 watts at 4.9 and 1.416v if i use 1.08v as my stock vcore (I need 1.25 to run at 4.6 lol). Is that way too much for this board?

what i read about till now, and what you and others said about it too, seems like it,
but whos to know, im not that technical, i can look for answers, and what i think is right,
by comparing what people say about things..

if 9 of 10 peeps say , this is right or this is wrong, i assume its like that,
but i still go through alot of reading/searching, before im sure about anything,
and maybe then i say ...yea, they are right..or wrong ..lol

i just dont know enough about this, to give a clear answer,
i only know about it for like ..2-3hours? biggrin.gif
and it gives me a headache, all the technical talk..lol

but i wouldnt go out there warning people about it yet,
its not at all clear yet if the mobo degrades after a while , if you oc with it,
its only few posts here and there mentioning it,
and some of those only mention sin's post, and use that..(as a absolute truth)


o well, time to hit the hay..lol..nite smile.gif

i had 1.65-1.75V most of the time, now its back at 1.8V ..lol
someone did tell me to put it back on 1.8V for higher OC's tho,
but that was when i tried to get 4.8-4.9ghz oc's
you can go over 1.8V, but i dont have experience with that,
have to ask others about it..

I could use 1.50V PLL up to 4.9GHz, fully stable.
for 5GHz it required 1.55V PLL to be fully stable. for anything above I just use stock 1.80V to rule out instability coming from PLL wink.gif

the difference in temps under load from lower PLL are very small, maybe 2-3C at most. it also helps some people to keep iGPU disabled (however in my case it didn't matter).

what matters most per vcore stability and demand is the HT - with it disabled the vcore demand on 3770K drops drastically, but so do the multi-threaded benchmarks as well LOL! another thing is the speed of memory! with 1600MHz on RAM the vcore demand will be lwoer than with RAM running 2400MHz (or 4 sticks as opposed to 2 sticks) - it's best visible at 5GHz+ clocks on CPU.

either way, just updating my status - my CPU has been sent and received by Intel RMA (under Intel's overclocking warranty plan this time), waiting for replacement and hoping to get something decent.
