Worth the $$$?

Wasn't that expensive. $350 isn't awful for a CPU IMO

On air with my CM V10, just playing with it.

 

[kannas]

I just checked your thread and I think I know the problem. The 8350 pulls a lot of power and the VRM on the 99fx pro wouldn't hanle mine much over 4.5. Even if you have fans on the VRM
and on the socket at the back of the board it'll still be limited.
Mine are rated at 11's 2133 1.65v
I can run it at 7-9-8-24-33-1T with 1.8+v

so i cant go above 4.4 on this MoBo??

that's really sad..

 

[kannas]

well i lil more is too much m8
try reseat use less

tried reseating too with less TIM same results...

Is that the 9370?? Looks good for air that V_core is right in line with an 8350 on water.

Not too likely. If you get really creative with some fans on the VRM and one on the back of the board you might get another 1-200 mhz. Like I said I had the same board and with the 8350 4.5 was my max stable.

@ D1nky

I found it My buddy had orders to crank up another guys 6300 to hit 5.5, he did it on the Fatlady with 1.728v http://www.overclockers.com/forums/showpost.php?p=7408179&postcount=2

So I PM'd him and this is what he gave me for specs. He's an old DFI mobo employee and knows his stuff

Re: Fatlady



--------------------------------------------------------------------------------
Just an FYI heads up.

Asrock 990FX Fatal1ty Professional

Vcore ++++ BIOS between 0.6000 Volt and 1.7500 Volt in steps of 0.0125 Volt (Vcore depends on CPU)

VIO/VDD ++++ VMem (DDR3 voltage) 1.250 - 2.065 Volt, NB 1.110 - 1.655 V, CPU NB 0.6000 - 1.7500 V, HT 1.110 - 1.390 Volt, CPUVDDA 2.56 - 2.70 Volt and PCIE 1.81 - 1.92 Volt.

So it is possible just have to figure out how to remove your limit..

 

[d1nky]

^^ thanks, its kind of easier to get a lower TDP chip pass certain volt thresholds.

ive tried adjusting all the volts and pushing more, even have vdda 2.70.

Ill be benching this weekend and testing more, lol ive even read rgones posts on the fatlady before when googling it.

I still think there has to be some area in the bios that you can shut the safeties off. Since that's what I believe is stopping you from going above 1.66v. He said if he had it hooked up ATM he wouldve checked it out but he's back on his old CHV

 

[d1nky]

theres not many people that have gone far with this mobo, im waiting on asrock to see if there is an extreme bios. ive searched the user manual and bios many times. its lame lol

it doesn't like the volts at all and its a battle.

when I get some spare cash I may even buy a CHVF to see what the difference is.

thank you for helping tho

#edit: ive been doing some reading and seems people keep their LLC disabled to and adjust volts from there, ive always kept it 25% to keep voltage equal to bios set

ill test it out tonight

 

[kannas]

will replacing the stock fans of corsair h80i with the other fans that have high rpm and cfm help in decrease temps?

coz i noticed when i run fans at quiet mode the temps are 4-6 C higher than running them at max speeds.

That's fine but not what I was getting at. Reducing the core temp may help but your real problem is the socket/VRM getting hot and heating the rest of the board. With the H80 cooler you have taken away most if not of the airflow you would have had in the socket/vrm area, an air cooler would create some movement/turbulance there. You will need to put a fan in pointed directly into that back corner of the system and if you have a hole in the mobo tray behind the CPU put a fan there to move air over the back of the MOBO socket/vrm. Both of these will help and like I say may give you another 1-200 mhz.

So can you acyually set the voltage over 1.66 or does the board stop there. Like I said mees with the monitoring/safety section, dollars to doughnuts there's a failsafe that needs to be disabled.

what happens is, I could select any voltage pass 1.7v and boot. but soon as the cpu is stressed/benched it hardlocks.

the more demanding the test the lower level of volts it can handle.

for example, superpi can run any volts. 3dmark maxes 1.6v no matter the clock, and cinebench is limited to about 1.65v anyclock

Definitely sounds like a fail-safe. Over-current protection on the VRMs possibly?

that's what I believe and cant disable it.

I know its not the psu, ive tried two 1kw psus lol

My 8320 is stable at 4.6 with 99FX and the limiting factor is that i can't push vcore past 1.44 on my air cooler (core temps get too high). I do have a fan blowing on the back of the motherboard where the VRMs are located.

What I want to know is how Durvelle has his cpu at 4.7 on a board with 4+2 power phase. That's crazy.

its actually at 4.8GHz

bwahahahahahahahaha


and i think you should do more research on my board

Now I'm seeing the light.

Either this or your VRM just can't take it but I'd go with the first. Don't know wher it may be on your board D1nky but mine was located in the Digi power section. I set my NB to 130% and the CPU to 140% overcurrent. Also I think Phase control to extreme.

I'm pretty sure his is 6+2 and he also has a H2O set-up which helps keep the temps down. These chips are sensitive to temps the lower the temp the less V_Core needed for the same clock.

I seriously wish I had these settings, this is what I have. (although a different skin these days)

[Johan45]

And I assume you've checked all the sub menus like ACPI and CPU configuration. Shouldn't be in ACPI but ya never know if you do have an option the is APM disable that. It lets the software control the power.

 

[Irony]

Yeah like dinky said thia boards bios is very simple. APM os disabled on mine, every powersaving option is disabled but it still hardlocks or doesn't even boot much above 1.6v usually, you can set it up to 1.9v I think but it wont even post. Theres no overcurrent option in it.

Well that's just lame!!
I know when I had my old cooler that's what would happen to me but I have since over come that limit. This may be cooling related. I mean were talking in the 5g range for clocks and maybe yor loop is at it's limit. Cinebench is much more demanding that Pi so that makes sense that you could run 1 and not the other. Previously when I ran cinebench over 5.2 that's exactluy what happened to me froze up!!

 

[Irony]

Maybe so. Cpu gets above 50c easily at 5ghz. Still I would love to try another board. I'm out of money now tho lol. All of my computer spending will have to wait

 

[cdawall]

Yes it is the v10 I have is probably about as cold as you can get air cooling. Tore down that case and reinstalled my ch3/B97/sammy's for the htpc and will be prepping the watercooling case later today/tomorrow.

don't you also have a 8350

Nice I'm interested to see what this will do with some decent H20. Buddy of mine has a "good" 8350 on water and it runs prime stable at 1.5v even. My piggy is in the 1.57 range to remain stable.

I know having to pay for things is highly over-rated.

Any stability tests done? Any throttling?
