but possibly you need good cooling, i would recommend filling out rigbuilder ( see my sig )

Lol, im not about to spend $200+ on a mobo if i end up with the same OC.

No, I can't run it everyday even with water as my House Ambient is high at way over 30C. And the chip is a pig. Needs 1.6 and over for sustained 5GHz.

But yes, you will find an extra headroom from your mobo to a higher end board. Still, as @Mega Man said, you can try. Where are you on your OC by the way?

I cant really go much over 1.5v without running out of cooling.

Case: NZXT S340
Mobo: GIGABYTE 990FXA-UD3 V.4 Bios F3 custom cooled VRM and NB.
CPU: FX-4350 @ 5.2ghz @ 1.476 volts under load
CPU Cooler: Corsair H110 with 2 Noctua NF-A14 industrialPPC-2000
GPU: Soon to be 2x GIGABYTE R9 380 4gb
RAM: 8 gigs Corsair vengeance @ 1600
PSU: Corsair CX750
HDD: WD 1T blue
OS: Win7 64


I found 1.5v set in the bios to be my max voltage due to cooling. I was told i dont want the chip to run over 60c durring stress testing. At 1.5v set in the bios the pc idles at 1.488v and droops to 1.46v P95 small FFTs. LLC is Medium which i have tested all the settings in the bios and this is the best its got. All other settings droop worse except extreme and it vboosts like .25+ volts.

So with that voltage i can run 4.8ghz stable. Less voltage and its unstable on occasion at 4.8ghz. 4.9ghz isnt even remotely stable even with more voltage. At 4.9ghz and move voltage was stress testing at 68c and it still failed IBT standard...

I basically only play with the multiplier and v-core. I have taken a few of the other voltages settings off auto and just set them at or slightly higher than their default but im guessing here as i lack the experience to really know what to do.

Others have had much better luck with the 8370E. Reaching 5ghz stable at 1.5v etc.

the e chips aren't a guarantee either I was hopeful with mine but it turned out to bed mute voltage at high overclock then my base 8320...

Yeah, i mean i know nothings a guarantee with "overclockabuility". I just assumed that the 8370E was probably one of the better overclocking fx chips. I did research for a good 3-4 weeks before buying it and it seemed like most people could get 5ghz with less voltage and a lower temp than the typical FX-8350. Im still not sure if i just struck out on the chip or if something else is going on.


EDIT: Examples... http://www.overclock.net/t/1531498/fx-8370e-4-8ghz-at-1-38-vcore-this-thing-is-a-beast-pushing-further

"4.8ghz @ 1.38v"

"4.9ghz @ 1.44v"

"4,7Ghz with 1,325 vcore
4,9Ghz with 1,39 vcore
5,0 with 1,425 vcore"

"5.1ghz at 1.40"

"5ghz at 1.42"


So when im sitting at 4.8ghz at 1.5v(bios) 1.46v load its kinda frustrating....

True. It's all about the lottery unless you can pick the known good batches.


@JerDerv

I can't really speak for your board. But the rev3s are boosting the VCore on any LLC setting. I also found them heating the processor way higher than good boards. Probably due to power delivery. These good boards somewhat provide better / cleaner power to the CPU.

Lastly, there is also the issue of the VRM section on the UD3s after rev 1.1. These new boards doesn't have powerful VRMs for the FX. They instead opted to use 2 lower rated VRM chips per phase. They have executed the idea bad and maybe on purpose to distinguish the higher tier boards such as the UD5 and the UD7. Earlier UD3s I believe have the same Power Components as their UD5 and UD7 boards.

Ok, new custom loop is complete and running perfectly. Comparisons below with the same settings.
Warning: Spoiler! (Click to show)

With H110i (with temp spike)


New loop (with temp spike)



4.93GHz is high voltage and temps are 52 but something isn't right and still working toward 5GHz. The Corsair H100i did a wonderful job though.

Very good looking system. Forgive that I am not help regarding the spike, but your photo is a treat. bigeyedsmiley.png

Has anyone heard of a UD3 v4 exceeding 4.8? I have not, but have seen a few who all stopped at 4.8. The first was with a 9590. Some have speculated that it is designed to stop there.

You might still drop the temps if you put fans on the 60mil 240. Just saying. thumb.gif

BTW, can your chip run at 250 FSB?

that's honestly not bad assuming it's good and stable my e chip needs 1.512 under load to be ibt stable @ 4.8 but undervolter would love this chip for his purposes I can pass ibt with 1.1v at 3.2 lol....but yeah I think mine was batch 1423 maybe? Have to dig up the picture...
