brb going to puke.....

we don't need to here if you can't help

if you are using an aftermarket CPU cooler, you can use the stock 90mm fan that came with the FX CPU stock heatsink in a getto mounted fashion to blow on the VRM's, yes...that could help but it's only a band aid over a decapitated leg sort of speak.

oh i did the same with a crappy board i have and the vrm temps went down 8c

[FShiwani]

Alright, been playing for a few hours and not once has it hit low FPS. And I checked the max temp and its 67 degrees which was from P95 test.

thats all great news as long as you won't miss the performance you would get at stock clock speed and volts and let alone overclocking...you could now try to slowly reduce voltages even more until it's no longer stable, when you reach unstability raise voltage up one notch and leave it there...or if youre happy with the temps at 1.3v and it won't throttle you could also slowly raise frequencies the same way until unstable.

Is the current clock that I have is it much lower than stock or just a bit, because it looks like its only been reduced by 100mhz,

indeed the stock clock speed on these is 3.1ghz lol...i thought it was higher than this...so basicaly leave it at 3ghz and see how low you can reduce voltage while remaining stable...lower it one notch at a time and take your time to play a lot of games and stuff before lowering it again making sure it's stable at every step down...i would like lower it one notch every day and see how this goes...the day that you get a crash then raise it one notch and leave it there forever or until you get a proper motherboard to clock it at 4.4GHZ

Alright. Is it normal for the temperatures to throttle when using P95?

[i_build_nanosuits]

yes P95 put much more stress on your CPU and motherboard than any games out there...

[FShiwani]

I just reduced it to 1.29V, and ran OCCT, it got to 68 degrees before throttling. Is a OCCT test or P95 test enough to ensure stability ?

[FShiwani]

I really appreciate your help. It all seems to be fine now. Currently at 3Ghz and 1.29V. I'll go to 1.28 tommarow and see if its stable. Although from 1.30V to 1.29V I havent really seen much of a temp difference.

-snips-

your board has a 4+1 power phase (i have one of those boards) and your vrms cant handle the power draw

get a new board before you do anything else.

edit, seen nanosuits got there already, yeah ud3p is awesome (m5a is awesome too, just not for fx8's)

It seems fine at the moment. I'll see how long this lasts, VRMs getting too hot in summer, especially with the high temps this summer.

keep lowering your voltages if you can't afford a new board, as i said lowering it like 0.01volts every day until someday you play a game and get a crash or something like that and then youll know you went to far, you could even lower it to 2.9 or 2.8ghz if that allow you to go to somthing like 1.25volts on the core it might be worth the performance hit to get better and safer temps and lower the stress on your motherboard cause as i mentioned already this board you have isn't meant to support anything more than an FX-4130 or FX-4300 really...

i should think it'd be fine with a 95w tdp parts (is fine with my 4ghz phenom x4's) so could be good with an fx6300, infact op could possibly disable a module and carry on as a 4ghz fx6300 probably.

As of right now, I really don't do much work that requires 8 cores. Would disabling 2 cores make a noticeable impact or is it not worth it ?

If I do buy a new motherboard I want to be able to add my existing fx 8120 to it

i'm not sure if your motherboard bios as the function that allow you to disable modules (pair of cores) but if it does, and you need only 3 of them...this could allow you to lower voltages further more and/or allow you to increase frequencies, yes.

I did see that function in the bios, it was allowing me to disable some cores. Anyways, it seems to be running stable now. 

Thank you so much for the help.

you are welcome!

you are welcome!

I found this in the BIOS after I changed advanced core clock calibration to per cote and then changed active CPU cores to manual. Is this the right way to turn off 2 cores?

[i_build_nanosuits]

yes, turn 7th & 8th core value from ''on'' to ''off'' should disable the 4th module indeed.

[FShiwani]

yes, turn 7th & 8th core value from ''on'' to ''off'' should disable the 4th module indeed.

I switch them two off and Windows said its no longer activated. So I turned those two cores back on and now it says activated on 26/06/14. I heard that Windows 8 has 3 activation uses available, did this use one up? 

EDIT: Actually nevermind about that, I read it wrong online I think. Anyways Im gonna keep it at 8 cores at the moment since its all stable now. 

Played for 3 hours straight last night, and max temps it hit was 57C.

Okay, I am planning on getting an Asus Sabertooth 990fx R2. After looking at reviews it seems to be high end and similar to the crosshair V formula except without the fancy features. Is this is a solid board and will it solve my issue of high temps and VRM throttling ?

The motherboard i used in my rig would probably do it, It got my 8350 to 5.0GHz with no problems at all, no throttling. That ASUS board is good, I could certainly vouch for it.

[FShiwani]

right now I'm getting really high temps again even though I'm undervolted and underclocked, like 60-65, but sometimes it said 76 on hwmonitor max after a crysis 3 session, and fps drops to 25-30 sometimes every few min. Could this be caused by the VRMs, will the new mobo fix it ?

Not at all, bad vrm would most likely give issues like your pc randomly rebooting or the clock speed throttling etc. Also I'm pretty sure its artic silver 5. I always failed with it, never managed to get proper temps with that paste. Paste like nt-h1 or mx4 are really noobfriendly and you can't go wrong with them.

[FShiwani]

Alright. Okay let me illustrate the complete issue. 

'When I run P95 for a couple of minutes, what happens is that CPU Core Temp goes up to 67/68C and stays there for around a minute or so, the VCORE up to this time is 1.176V to 1.248V, 106-116W being supplied up to this time, CPU is at 2.8/3Ghz up to this time. After staying at 67/68C for around a minute or so VCORE changing to 0.864V and temperature drops extremely quickly to 52/53C, 25-60W being supplied at this time and CPU goes down to 1.4Ghz and stays there until the temps begin to rise again.

During these brief moments of the VCORE dropping and Temperature dropping is when I experience my drop of FPS, in several games, such as in Crysis 3 I get 100+FPS on Medium in closed scenes and it would just drop to 30-40fps. This also happens in games which are easy to run such as World of Warcraft or League of Legends and used to be much worse, it would go from 120fps to around 15-30fps. However after undervolting and underclocking it was much better and temps were better, but its starting to happen again. Temps are much higher now. Temps idle used to be 30ish, now they idle 40ish. Undervolting certainly did help. After gaming I see that it sometimes spikes to 72C/74C, which is way too high.

 

This current motherboard(Asus M5A78L-M) has 3+1 Power phase, the Sabertooth 990FX R2 has an 8+2 Power phase. Will the Sabertooth 990FX solve the issue?
