During stress test vocre reading are almost 0.1v lower vcore set in bios

I set 1.40v ... read 1.31 -1.29

LLC options in this mobo are: auto, 1/2, 1/4, disable.
For am3+ must be 1/2 according to bios help.
I'll try different values of LLC.

edit:
for 4ghz 1.375v passed first prime tests, LLC=auto, vcore readings 1.272,1.280,1.296v

I don't know how your 970 Extreme4 responds, but my 990FX Extreme4 had the most stable vcore with LLC disabled. Be careful with your VRM temps as well, as these CPUs take a lot of juice and can easily overwhelm and/or kill the cheaper boards.

 

[qu4k3r]

I tried LLC=disable and gave the best results vdroop was almost ZERO
So I can lower vcore for the same frecuency

 

[Sempron Guy]

Now I do remember in several Asrock reviews that their implementation of LLC is backwards.

 

[Irony]

Can try turning LLC on if your vdroop is really bad. Those volts do seem a bit much for 4.0, my 8350 is stable on stock volts up to 4.5. Anything faster it spikes to like 1.5 tho lol

Whats ur northbridge speed? I don't see it on there

 

[qu4k3r]

HT and NB = 2000 MHz.

4GHz(20x200MHz)
1.3250v ... Prime95 fails at 54min, but LinX 1hr pass OK, temps are ok in both.
1.3375v ... Prime95 freezes at 7min.
1.3500v ... prime95 freezes at 57min, and temps raise up to 65ºC.

I'm a little disapointed

 

[Irony]

So, those different voltages and everything are all at the same speed? 3.5v isn't excessive, dont have to worry about harm done by volts. Are you using the stock cooler still? 65c really warm for 4ghz, I would venture to say that's the cause of your instability there.

I guess stability is always in the eye of the beholder, but in my personal experience if it lasts more than 15 minutes on prime its never crashed for me gaming for hours on end.


Also, you can probly bring NB and HT up to 2400 without having to increase any voltage. Some people say it helps alot with OC'ing

 

[qu4k3r]

Yes, all those voltages are at the same speed.

I'm using ocz vendetta cooler in an open frame case helped by , but I will use evga superclock cooler after change all parts and put them into a new antec one case.

I know stability is subjective thing. I used to run stress tests up to 8 or 12hrs. Once once I did it 27hrs. But it was on a high end mobo, not a cheap one.

Anyways, I'll try raising NB and HT to see if could help.-

Don't touch the nb and ht yet, leave it on default for the mean time. Your temps is your limit obviously, 65c is already pretty hot given the voltage.

 

[qu4k3r]

When I run prime95 I always choose "blend", not small FFT nor large FFT, but they said small fft is enough to be considered stable.

I gave a try to small fft and guess what... ran stable 1hr 10min

I agree 65c is comfy but maybe vendetta cooler doesn't help too much. I think it's a little weak compared to the other cooler I plan to use, and I really hope that superclock cooler solve it.

my temps at stock stay around 23c

(8320/8350)
pardon my pettiness& offtop, but is the extra 500 mhz worth the almost $50?
almost no one is talking about the 8320...

yet when it comes to the 63xx
no one has the 6350 which is 400 mhz more then the 6300 and the price diff is only $20

 

[d1nky]

most 8320s i know of can oc the same as 8350s

im not sure on the complete differences, just that ones clocked higher.

if you look for deals etc, sometimes the price difference is smaller.

tbh it probably isnt worth the extra!

 

[Irony]

Ya I don't really think it's a $50 dollar difference. Essentially its the same chip, might as well pocket the extra cash. It probably wont able to OC quite as high, but ya never know. Sometimes you get a golden chip. If overclocking it to the max isn't the intent then just do the 8320

 

[techtard]

I went for the 8320 and invested the difference into watercooling.
I don't think it's worth it to spend the extra ~$50 for the FX-8350 if you know how to overclock. Get the 8320 and a better cooler!

Well the FX-6350 was just released last may and even if it's already available at the time I bought my FX-6300 I'd still opt for the latter. I've got no plans using the stock cooler anyway and piledriver chips are walk in the park getting to 4ghz. I've only consider the FX6350 if I'm looking for higher headroom in overclocking as "most likely" it can oc'ed better than the FX6300, same with the FX-8320 - FX-8350 but I could be wrong though.

 

[SetsunaFZero]

my FX8320 runs fine to 4.7GHz everthiny above 4.7Ghz needs better cooling

I would disagre with that statement. Small fft works almost entirely the CPU. The blend test incorperates the Ram and the important part the IMC. When I'm clocking for benching it's the IMC that will crash the system on these chips. If you're having problems with the blend test get your HT and NB up a bit higher. I would also suggest your voltage is a bit low for that speed. 1.35 to .37 would seem more suitable to me.

It is NOT $50 more. there are several places including Micro Center and online right now at Newegg you can get the FX-8350 for $179.99 . If you buy a motherboard at Micro Center, you save even more. For $30 it IS worth the difference. You get higher overclocks.

I agree 100% the 8350 IS worth a $20-30 premium over an 8320 imo. However, in markets outside of the USA the difference is closer to $50 or more.... which would make it more worthwhile to try the lesser chip and hope you get a good one.

Tried that myself with an 8120 but the chip couldn't handle an OC without blistering level of heat and stability issues- got an 8150 and got 4.0Ghz w/o changing the heat output or power usage from the chip

 

[os2wiz]

If you're looking for a decent monitoring software. HWmonitor(free) works quite well with Asus and the FX chip.

Actually the better program is HWinfo. It is more accurate with temps.

I don't believe in hoping. I believe in science. Science says your odds are far better with an FX-8350 for overclocks. There are some 8320's that are exceptions to the rule. Most often you getbwhat you payfor. The Iphone has always been the exception to that rule. Enough said.
