AMD FX OC'ers Club

PC failed to wake up even with stock CPU setting (4 ghz with 1.325v + no turbo). Since the PSU is almost 5 yrs old and seen lot of gaming load close to 450w, like some others suggested I am thinking of changing it. Since I have to fix this over the weekend, can't wait for online orders. I have few options from my local store, please help me pick a decent one. Don't have money to keep throwing at this, so want to keep it close to $100 (+/- 20).

I think 750W should suffice for what I have. If I want to go adding another 7950 will the 750 still be good or better off with 850W?

My store is Orange County, so if you guys see something that is really good, let me know.

And oh, I want it to be as quiet as possible.

i clear cmos and nothing hapend!! still 4cores/4threads...,then i reflash bios to the stable one F9...,and again didnt help..,still 4 cores...,then i remember i have once change the setings in msconfig to use 4 cores..,and that was it..,now it all 8 cores enabled!! now to OC this biatch

Take that one PSU's are the most efficient when they run at 50% load and it's 80+ gold rated and will most likely turn the fan off when the PSU isn't under much load and running cooler

ohwell we live and learn good to hear it's back to 8/8 for OCing start with stock volts and up the multi until it crashes then up the volts a little more then the multi and so on and so forth until you get as high as you want to go and its stable

Today's newegg deal

This one kind of put me in dilemma, should I buy this instead, I know I have to wait and probably drop adding 7950 idea. May be just go to GTX 970 instead.

Saves me few $.
 
you know what gives me most trouble!! i cant boot with memory on 1866mhz,even without any cpu OC
i got no idea what is wrong..,i hope its not cpu!!
EDIT: memory is rated at that speed,and this cpu have suport for that memory!! so what is the deal!!!
 
check the voltage for the ram anything under 1.65V is probably going to lead to problems at 1866MHz
 
ok made 4.4ghz on 1.45v core and memory on 1600mhz...i had something in memory setings on manual and just put it on auto and it booted up!!
how much cpu NB volts is safe?? i think i made it about 1.35v
and does anyone know how can i save this bios setings becouse if i change anything and it fail a want to be able to load this profile!!
EDIT: after few hours of gaming pc is stabile... maybe later try increase ram multiplyer to try 1866..,but first i wana make sure that pc i stabile as it is!! if its not i dont want to add more instability :)

I think I found the problem. ITS A BUG IN THE BIOS (seems like it).

Every time I change the LLC setting to medium (other than Auto), I see this Black Screen/wake from sleep crash. If I leave it at Auto then no issues so far. All the Overclock profiles and even default clock profiles that I had saved, I had the LLC at medium. I change it to Auto and PC seems to be stable, after several IBT, BF4/BF3, Facebook, Youtube, Sleep/Wake cycles.

So its not the PSU. Good I haven't yet ordered.

I am at 4.4 Ghz with LLC set to Auto. Voltage set in bios is 1.38 and with IBT load it drops to 1.32/1.34. During gaming sometimes it jumps to 1.4v. CPU stays around 46 during Gaming.

Hopefully that is the problem and it behaves well.

I feel like my half bald head is close to full bald, in the last one week, at least I don't need to go to the Barbers!!
 
@Pehla There should be a place in the tools section of bios to save profiles. Although I'm not that familiar with Giga boards.

@suraswami Sorry been out of it for a few days. I hope that get's it all sorted out for ya. This has been dogging you for too long.

Pehla has rev 1.0, don't think it has the ability to save profiles (may be I am wrong).

Yeah this has been driving me nuts, over the weekend I had one crash, but I think I need to adjust the voltage a bit.

not going to spend anymore time on this, need to catch up with life!!
 
True...,i looked for save profile setings in bios for some time but didnt find it...,maybe i overlook....,but dont realy think that is the case
I will search for it again as soon as i go to mess with OC again...,but for now im stable at 4.4ghz /ddr3 1600mhz
 
Like I said the only real fix is to just shut the PC down. You're not alone with the Sleep/wake probles swami. As for the Giga board I only have one a GA-EP45-UD3R and it doesn't save profiles so that wouldn't surprise me.

I found this in your mobo manual
ud3 bios save.JPG
 
found the save profile setings...,and i thank you for that !! :) now i dont have to redo evry setings that i did i OC fail!!
but i must tell you i was wrong when i told you my pc was stable at 4.4ghz/1600mhz mem!! i know i changed memory multiplyer and that it showed me memory speed of 1600mhz...,but today something was bothering me ,and i started cpu-z and notice that memory again work on 1333mhz..,so first i did is save profile and try to change multiplyer to x8,x(1600mhz) and again no boot
so i reverted all to default and just put the memory on 1866 mhz no cpu OC at all.
And it booted!! now i will try to increase cpu multy just step by step.., and let you know how it goes!!

If the memory is rated to run at 1866, check the memory voltage and also Try increasing the CPU NB voltage to compensate for extra load.
 
Like Swami said most likely the Ram voltage needs to be around 1.6-1.65v but check the specs. Also make sure you set the timings since it doesn't always do very well on auto.

My thoughts exactly.
 
already put memory votlage at 1.65v and give some cpu nb some volts too!!at 4.4ghz no boot..
but just now when i started pc,went into bios and give cpu to 3.8 ghz just to check if it boots and it did..will first play some game tonight..,and tomorow try increase cpu multi a litle bit more...

What do you have VCore and CPU NB voltage set to? They may be a bit low, even with the bump you gave them. My CPU NB took a good bump to run 2133 C9 stable.
 
At a guess I'd say v-core needs to be around 1.4v maybe a bit more and CPU_NB up to 1.25-1.3v for 4.4G. This all depends on your CPU of course. Some need more
 
v.core is at 1.45v and cpu nb was 1.35v but now lover it to 1.3v and booted at 3.8ghz cpu and 1866mhz mem
edit; thank you all guys for suport!!
 
Man those voltages do seem kind of high especially at 3.8
You're welcome
 
I finally got my 8350 up, whats the stock volts for this thing running in turbocore?
