don't matter 95watt or even 80watt cpu, i have enough experience with 4.1+ boards to know vrm's overheat quite easy heatsinked or not, now if he left hes chip at stock and under volted the cpu, that should drop vrm's teams quite bit and make hes board last a lot longer tell he can cough up the dough to get a better board, as for hes psu i never once read saying he had a sfx powers supply which i never heard of the make so its more then likely its generic
you do understand that all a 8+2 VRM board is a 4+1 VRM design doubled over and parallel. the reason a 8+2 runs cooler is because it uses smaller less high watt components to achieve the same rating. those MOSFET components are all spec'd to run over 120C. you apparantly have "enough" experience with shitty 4+1 boards. give me a good solid 4+1 phase board (DFI 790GX) and i would put money i could beat your clocks on your pick of a similar 8+2 phase.

as for the PSU generic or not he does not have a high watt system he has a 95w phenom a couple drives and a midrange GPU he might pull 250w under load.

the vrm's and ferrits may withstand 120c yes that doesn't mean at those temperatures the board will not degraded or catch on fire and may take out other components with it and not to mention its a fire hazard waiting to happen, as for 8+2 phase technically being 4+1 but doubled i am not sure where you read this from?, now the only reason all us hardcore enthusiast like myself tend to go with 8+2 phase or higher boards cause we all know the power delivery is spread ed more evenly in thus lowering overall temperature's on vrm's and chokes, and last cdawall i never meant to disrespect u or anyone nor turn this into a overclocking competition, look bottom line i know u been on this site for a good while and well respected why would i cause any beefs

the paralleling in a 4+1 VRM design to make a 8+2 design is from talking to the board designers and being on XS for quite a while. not to mention AMD spec is a 4+1 system that system is then licensed out to board manuf. Asus, GB and everyone else do not recreate the wheel they parallel the mosfets and for every one phase in a 4+1 design you now have 2 making it a "8+2". Again smaller phases can be used this way which will operate at a lower temp. with said electrical components running at a lower temp you have more stable power delivery.

as for a fire hazard i think not. silicone doesn't exactly burst into flames nor do any of the other components. new boards also use digital chokes not the old school ferrite ones well at least on good new boards. considering i have personally baked GPU's, CPU's and motherboards in an over at 500F i can personally tell you 120C (248F) isn't going to cause spontaneous combustion. I can also tell you that most of the components on that mother board are spec'd between 120C and 250C.

if you need anything else answered LMK

So I've been working on my memory again after seeing Jr's results. I have a fan directly on the NB now and turned up the case fans :)

I managed to push a higher CPUNB which resulted in -



Not bad for 4 sticks :)

EDIT - It's still allowing me to clock the CPU back up!! Also tweaked the Row refresh cycle down to 90ns for each stick and voila.....my best ever result :) Happy with that!!

Gotcha! I just wanted to state the obvious, with a new board and ram this cpu feels and clocks quite differently tbh. Having a hard time actually finding out what's good and what isn't. I'm going to have to mess with this ALOT more than what i was used to. Quite a bit more values I can tinker with :D

Did You guys knew that ASRock 990FX Fatal1ty Pro is the FIRST AMD based board
with V12+2 VRM regulation?

Works like a charm! :toast:

i am pretty sure all the new 990FX boards are 12+2 regulated.

Hate to correct you. 990fxa-ud3 is an 8+2 design.
meh don't care :laugh: a good 8+2 is still just as good as i think i have explained like 50 times so far.

I just don't get that, what do you mean by "All of the base 990fx boards are more of a 990x than anything else" ? You guys got me confuzzled and mindblown? I thought 990fx had more lanes so had could they be the same!?

All of the base 990fx boards are more of a 990x than anything else watch all of the high end ones. Sorry I should have been more specific
Im talking about regulation.

ASRock 990FX Professional is the FIRS AMD V12+2 regulated board.
All other are just V8+2.
