Mild CPU overclock and Ram Clock issues FX-8350 ASUS M5A99FX Pro rev 2.0 would like suggestions

post #1 of 3
Thread Starter 
Hi all- first post after doing lots of reading for the last month or so with just some questions about overclocking with the FX-8350 and ASUS M5A99FX PRO rev 2.0 (CPU cooler is a CM Hyper 212 EVO with push pull fan config.)(700w OCZ modular PSU pulling air from bottom of case)(CM HAF 912 case w/200mm exhaust fan, 120mm on back as exhaust, two 120mm front intake, 120mm side intake)

It’s been a long time since I Built a PC completely from scratch and I want to make the most out of what I have without putting too much stress on the hardware so Temps being low are a must with a mild overclock is all I’m trying to achieve unless someone sees a serious bottleneck in my configuration. There are many new settings compared to the last time I tried overclocking and the guides I've looked at have helped a lot but i feel like I'm stuck where I'm at now and would like suggestions on which way to go or if i should just stay put with where I'm at.

I was going to post about how I have been unable to get my RAM to clock up to 1866 G.Skill Ripjaws 4 x 4gb with 9-10-9-28 latency (running at 10-11-10-30 on a recommendation from a friend) but as of this morning I see to have been able to get a steady clock out of 1800mhz which after a week or so of games locking up, getting 1800mhz stable, I’m happy with it.

However, now my speed stepping seems to be off and I’m not sure what I changed that impacted that. Idle temps are low but I don’t feel like I need to be running at 4.4ghz across all cores just for web browsing.

One question I have is regards to what temperatures I should be monitoring since I've seen some conflict on what programs to use with that boards and CPU’s and haven’t come up with a clear answer for my combination see the following example:

Prime 95 27.1 Build 1 using Blend test getting temps from core temp between 55c-60c occasionally hitting 63
CPUID Hardware monitor (version 1.21 driver 136) shows 76c on CPU and 27c on mainboard when core temp is showing 61c, core temp seems to follow/correspond with CPUID hardware monitors “package” Temperature

Idle Core temp shows around 10c-14c (after running prime95 Blend test for 20 minutes and letting it sit for a while)

Below is what I have found to be stable where I run into trouble is when I set my CPU multiplier to 19 and my CPU bus frequency to 233 to try and get closer to 1866 on the memory without changing any other settings. With this I get FATAL ERROR: Rounding was 0.5 expected less than 0.4 what else would I need the change to get this working? Should I really be trying for that extra 66mhz? Is my HT link Speed set correctly, I feel like at 2475mhz I’m not getting the full bus speed from my board but the next setting up with those multipliers is 2700mhz and that seems like that would put me well over what the board should be doing/capable of (board says 5200mhz but 2700 would be 5400mhz wouldn’t it)? Is there anything that sticks out that NEEDS to be changed to smooth out system performance and relieve bottlenecks?

If you have questions as to WHY I might have anything set the way it is I did just from various reading I did around the web. I really still don’t have the best grasp on voltages and what to turn up or what to not turn up so please forgive my ignorance.

Uses: Gaming and some video editing (BF3, Guildwars2, Mass effect 3 and some Adobe Premiere Pro)

If you have any other questions about my setup I put all the hardware information I could in my Rig on my profile.

Thank you in advance

you disabled CnQ power saving features in the BIOS.
That is why your CPU stays at max freq all the time.

re enable Cool’ n’ Quiet in BIOS and make sure Windows Power Options
is not in High Performance mode (Balanced Plan should be fine).

Try testing your overclocking with just two sticks of memory (easier on
the memory controller). you can add the second pair later on and
get it stable.

CPU Spread Spectrum & PCIe Spread Spectrum should be disabled
PCIE should be locked at 100MHz (if you are going to use HTT over 200)

I would recommend you test you memory at stock CPU speed to find
max freq and timing. Will save you time knowing your memorys limits
before adding other factors like processor and motherboard into the mix.

Thank you for the quick Response.
re-enabling CnQ fixed my speed stepping - Thank you, I should have caught that but I've been staring at it too long rolleyes.gif.
I disabled CPU and PCIe spread spectrum and set PCIe to 100Mhz
after 30 minutes of Prime95 Blend test I'm still stable at 57c or 58c on average.

I should add that I had everything stable at stock speeds and was able to get the memory to run at 1866 without touching the voltages or any clocks. However, it's when I went from two 4gb sticks to four 4gb sticks that the problems began. That's why I've been adjusting Voltages and timings based on a few things I've read and some suggestions from a friend that recently set up an 8150 on an ROG board for a friend.

He told me setting the memory speed just by itself almost never works and the timings have to be set manually so i started messing with the voltage of the NB. going up much higher seems to skyrocket my temps and increasing the cpu bus frequency and higher seems to cause instability in the memory (at least that's what i think the (FATAL ERROR: Rounding was 0.5 expected less than 0.4) problem is.

any thoughts on my question about looking at temps using core temp vs using CPUID HW monitor? If CPUID HW monitor which temps should i be more interested in? Package, CPU or Mainboard?

Also, I'm going off the assumption that 65c to 70c is the max I'd ever want to push my temp, that's why I'm comfortable running stress tests and seeing just under 60c on average, when in games I rarely see temps over 38c
