im hoping to purchase an 8150 or 8350 next month sometime, but for now will be overclocking my 4100 to death. hoping to reach 5ghz

In BIOS V1.90 they got rid of John boys face in the BIOS - thankfully. You can disable the boot screen of his face in earlier BIOS versions. Asus mobos are over-priced because some people think more knobs to turn actually means better overclocking ability. This has not proven to be the case for the majority of people who have tested Asus mobos against Gigabyte and the latest Asrock AM3+ mobos. Marketing is why Asus can charge naive enthusiasts an excessive price for their mobos.

A 4100 might be able to run 5 GHz. stable. It depends on many factors. All you can do is enjoy the journey and see where it takes you on the frequency highway. smile.gif

I like the way you call it the frequency highway haha......and thanks. tbh I am a fan of asus but the pricing vs other brands is definitely a serious matter!

I have used a lot of name brand mobos over the past 20+ years and the only (2) that ever failed were both Asus. At one time they were arguably the best of the Asian mobo makers but that seems to have all changed when they decided to sell retail.

There is no real accountabilty in retail sales per se where as an OE supplier they had to eat the defective mobos and costs to service the defective mobos. In retail they do whatever they feel like doing. In my case Asus sent a used, dirty, dusty, hand repaired mobo as a replacement for a new, spotless mobo that failed in 3-4 months. I refused to install it and returned it at my expense. Won't get fooled again. wink.gif

I have used Intel, Gigabye, Epox, MSI, Asrock, etc. brand mobos and none of these ever had a defect or failure so you can see the issue in addition to Asus' absurd pricing. Perception is reality for many people so if the product has more whistles and bells these people assume that it will OC better.

In fact many reviews have shown that Gigabyte and other brands of mobos often OC the same components equally or higher than the Asus mobos. Asus uses multiple companies to produce their mobos and their review boards tend to show better results than what many consumers see with mobos actually purchased vs. the mobos supplied to PC hardware reviewers. Some reviewers also get a "special" BIOS that consumers do not get...

In the end I always suggest that people technically educate themselves and then make an informed purchasing decision based on factual information, not hype.

thanks! Its been despatched so hopefully be here tomorrow, I cant wait to get it hooked up and overclock to death and get some benches in! so far my lil 4100 is nearly competing with a phenomx6 and 7970 but this board throttles cpu at full load making the scores drop! new mobo and wooohoooo!!
post #195 of 416
Any mobo can throttle the CPU vcore and thus frequency if the mobo VRM circuit gets too hot. This is a safety feature to prevent damage to the VRM circuit. This typically only occurs on quality enthusiast grade mobos when the CPU is significantly overclocked/over-volted and you run the CPU under heavy load for long periods of time such as in stress testing where the load on all cores is 100% continuously.

If the VRM temp safety cut-in is reducing the CPU vcore/frequency then you'll need to increase airflow across the VRM heatsink to remove the excess heat which increases signifiantly with high core count CPUs..

this board has 4+1 phase design, not heatsinked and throttles after ten seconds when overclocked/volted.

how long does throttling take on the asrock? i know its vrm protection but a decent board and cooling doesn't throttle in ten seconds and stays at a lower frequency due to such.
post #197 of 416
Yeah that board is not designed for overclocking per se.

IME it takes ~45 minutes on my Asrock 990FX Pro before the VRM would get too hot and start throttling when running P95 or OCCT. A second fan on my CPU produced enough airflow around the VRM heatsink to eliminate the problem and I have since run numerous 25 hour P95 stress tests with no VRM overheating cut in.

FYI - Anyone interested in the 990FX Fatality Pro mobo should act now as this board has officially been discontinued by Asrock. The closest substitute is the new AM3+ Extreme9. The boards are very similar and full featured. For those who require two PCI slots, the Fatality Pro has 2x PCI slots where the E9 only has one. Newegg is sold out of the Fatality Pro and I imagine other vendors will be also in the near future.

yea I bought the last one in stock @dabs.com! well doesn't that mean we should start a club thread for this board.

ive got mine up and running and so far very impressed, bang for buck!!

a few issues; boots too fast so I miss the delete key every time to get into bios haha!
I haven't even worked out how to control fan curves, seems theyre are at fixed speeds. (levels 1-9)
and having problems getting stability pass 4.6ghz, I done all the basics put ie power states, turbo disabled etc. it doesn't throttle (controlled thumb.gif ) which is good but is there something im missing that improves or fixes stability?

vcore sets vid to what it is in bios. I tend to start with 1.5v and work down once found the desired frequency, LLC disabled. I used multiplier only. I upped internal NB to 1.25+ and something ive missed for sure.

EDIT: just done some research and noticed I had speed sprectrum disabled may cause instability wink.gif

IME each FX processor has a specific vcore and CPU-NB combination that provides the best stability when overclocked. The FX processors are the first that I have seen that will become unstable if you use too much vcore - which is different from prior CPUs.

You might want to try CPU-NB = 1.30v, HT = 1.25v, RAM voltage +.1v over default. On my mobo LLC works best @ 25%. The vcore can climb excessively without LLC set to 25% IME. This can cause both overheating of the CPU and instability even if there is no overheating. You can also try the Northbridge frequency @ 2400 or 2600.

If you go to the BOOT option in the BIOS you can set the "Set-up Prompt Timeout" to a higher number of seconds so that you can see the option screen on boot. FYI - you don't need to wait for this screen however, you can hold down the del or F2 key as soon as the PC starts to boot. When you hear a single beep, it is acknowledging that it will go to the BIOS screen.

These all need to be disable:

Turbo Core Tech
Application Power Management
Cool & Quiet
C6
CPU thermal throttle
C1E

The fan speed setting is an odd deal. You need to switch to manual mode before the speed options appear. Then you need to select the speed you desire and press enter. Then save as normal when you exit the BIOS.

Disconnecting the power and re-setting CMOS helps sometimes when the system has crashed enough times but I would suggest that you load the BIOS V1.90 and 1.80 on a flash drive. If you do enough testing of the limits of your CPU and RAM you will eventually get enough system lock-ups or crashes that the BIOS goes into a "stupid loop". When it does this, making changes in the BIOS do not actually work and the system defaults to to factory frequencies and voltages. The only means that I have found to get the BIOS out of the "stupid loop" is to instant flash the BIOS to a different version such as V1.80 - which BTW worked fine for me. Then you can go and instant flash back to V1.90 and you're good to go.
