this board seems nice. maybe its the british thing. americans are ********, thats a fact, and its just not necessary on computer hobby forums.

I'm an american who also enjoys the drama free uk forums. I don't know how many really good threads I've seen be closed because people attack each other over stupid things like amd vs intel and other trival things.

Just make sure you don't go into the graphics card section and say if you like Nvidia or ATI, people will have a go.


:D :D
 
i dont think anyone is getting 4.8 on air... 4.4 is doable but you need good hardware. 3.5ghz is guaranteed basically.

COMING SOON!? 4.4ghz prime stable test!?...... its possible anyway, prime is running stable. ill let er go tonight and hopefully post back with a blend test at this speed. the only problem is i found out it has to be 600mhz on the ram and over 1.4v on the cpu, so well see. i already noticed, in this configuration, it doesnt do pi any faster then 4ghz with 800mhz ram. and that is considerably less voltage...

i have no idea... dont know how to measure wattage used. well i mean i do i just dont have an easy way to do so. the higher multiplier would probably allow me to run the ram at 800mhz, i think i dont know. but if it did things would be a lot more proper...

just found out you have to enable the onchip gpu and up its voltage to make this crap work. unbelieveable, i had no business even getting to 4.4 at all. no wonder it was so unstable.

*crossing fingers this fixes my 3d games problem*

wait sorry, does upping the onchip gpu help the overall cpu OC? Caus I am planning on overclocking one with a dedicated gpu - do I still need to be concerned with the conditions of the onboard one?
 
YES. in fact, you must raise the gpu vcore a lot even if you use a pcie video card only. right now i have it 1.46 in the bios (which is probably more like 1.36 really with this board). this not only enabled me to boot with consistency, it allows me to play games again without any problems.

with this asrock, before you overclock, you have to set the onboard gpu sharing to 32mb. then restart. that will enable the onchip gpu settings to show up in the bios. only then can you up the video voltage and set the deticated allotment for the memory (i did 64mb here). its a small price to pay to keep your overclocks happy.
 
well it failed! after 2 hours, prime95 actually crashed. there wasnt any recorded errors or stops, the application just crashed. the pc was still sitting at the desktop this morning, idling all night.

it looks like it overheated though. realtemp showed that both cores hit 83c about the same time prime95 crashed. so i lowered the cpu voltage .05v in the bios and ill try again tonight. overall though, the system is running GREAT! these i3 chips are clearly limited by your hardware too, 4.4ghz for the silicone itself is a cakewalk. i bet, with the right hardware and a 25x multiplier, someone actually could get 5ghz on some serious air cooling...
 
well i dont even know if ill get my 8hr prime at 4.4ghz either.. im still playing with voltages though... one thing is clear, the onchip gpu does effect overclocking and not for the better. but at least it doesnt seem to hurt it that much either...

thanks for the info
 
why, if i may ask? i am already at 200fsb, and this motherboard doesnt seem to like it very much. it has been stable all day though! playing gta4, watching high def tv in windows media center, and cooking pizza. i dont think the pizza puts a load on the cpu but otherwise i think this is the configuration i want to get stable.

either this, or 4ghz with 800mhz ram. i dont think there is really any difference in real world speed, so whatever is more stable is probably what ill end up using. i had originally thought i could run the ram at 2000mhz at 4.4ghz cpu, but i guess i forgot to account for the fact that the fsb is extremely overclocked so it cant handle the ram at high speeds. from other overclocks i see, most people arent even running above 550mhz ram.....

That’s 4GHz, stable using the stock heatsink/fan. Part of the trick to overclocking this thing was lowering the clock multiplier. Despite always keeping the QPI and memory frequencies in spec, lowering the clock multiplier on the chip improved stability significantly and allowed me to reach much higher frequencies.

it doesnt seem to like that at all... 210 fsb and 21 multiplier and i cant even get into the bios. i think its clear that this, at least my motherboard, doesnt like 200fsb and especially nothing higher. that anandtech article is only at 190mhz blk, and from what i gather it takes quite a step up on a lot of things to get to 4.4ghz overall.... 4ghz might be the speed most people should shoot for

Watching this thread with interest, though I won't be buying until a mini-itx h55/h57 board turns up. Has anyone on here got one of these under water?
 
Can anyone suggest the best motherboad to overclock
MSI H55M-P31
GigaByte GA-H55M-S2H
GigaByte GA-H55M-UD2H
Asus P7H55-M Pro
Asus P7H57D-V - supports USB3.0 and 100 more then the other boards
