Ive dropped it to 4.5Ghz, Im swapping cases later today as my Silver Arrow doesnt fit in this one, prime95 passes the small fft's for 10/15 mins on those settings above but didnt like the voltage being so high.

Whats the likelyhood of it degrading my chip at say 1.55v if my system is stable and temps are good?

Cant believe the guy at scan was trying to palm me off with a single 120mm rad water cooler from antec as a replacement for this Silver Arrow rolleyes.gif

EDIT***** Just validated and changed it in my sig smile.gif

I generally run my CPU in the 4.5-4.6Ghz range just because of the performance to power range is so nice. Most CPUs need large increases in voltage above that for small increases in frequency.

There are a couple members of the FX8320/8350 Club that have run 1.55v since release and they haven't seen any issues. This is with daily temps under 60 Celsius which is more important than max voltage. So I would say the likely hood is pretty low on degrading an AMD CPU as long as your temps are ok.

I did make some changes. Not sure how this post ended up over here though

This Guide was created as a simplified method to Overclocking Bulldozer and Piledriver CPU's. I've listed the most important settings to change in order to reach stability, in order to take the guess work out.
FSB Overclocking is not discussed, as it's not required with a Black Edition CPU. **But if you know about FSB Overclocking, you can just use what you learn here, and apply it to that method.

Software
Warning: Spoiler! (Click to show)
Recommended Stress Tool is Prime95 Version 27.7 or newer Warning: Spoiler! (Click to show)
Known bugs and fixes:

1. Does not work on AMD Bulldozer processors. Fixed in gwnum 27.5 (there will not be a prime95 27.5).
2. Length 1280K FFT crashes on Pentium 4s with 512K L2 cache or less. Fixed in 27.6.
3. Hyperthread detection is not working properly. Fixed in 27.6.
4. The 6K 2^N-1 and 8K, 10K, 12K, 16K 2^N+1 AVX FFTs are missing. Fixed in 27.6.
5. Some exponents above 536 million generate roundoff errors and incorrect results. Fixed in 27.6.
6. FFT crossover points need retuning. Many can be more aggressive, but a few need to be more conservative. Fixed in 27.6.

  • Ai Overclock Tuner - Auto, Manual, DOCP
  • CPU Ratio - Adjusts the CPU Clock Multiplier (CPU Multi x FSB = CPU Speed)
  • AMD Turbo CORE Technology - Disable in order to manually Overclock the CPU
  • CPU Bus Frequency - A.K.A. FSB. This adjusts the base clock for, HTT, NB, CPU, DRAM.
  • PCIe Bus Frequency - Defaults to 100, not recommended to change, as it may damage GPU/HDD.
  • Memory Frequency - Adjust the Memory Divider. (DRAM Divider x FSB = DRAM Speed)
  • CPU/NB Frequency - Adjust the CPU/NB Divider - Defaults to 2000-2200Mhz
  • HT Link Speed - Adjust the HT Link Divider - Defaults to 2600Mhz
  • CPU Spread Spectrum - Disable - to increase overclock stability
  • PCIe Spread Spectrum - Disable - to increase overclock stability
  • EPU Power Saving Mode - Disabled
  • CPU & NB Voltage - Offset and Manual Mode - Change to Manual Mode for Overclocking
  • CPU Manual Voltage - ** Available under Manual Mode - Adjust the CPU voltage
  • CPU/NB Manual Voltage - ** Available under Manual Mode - Adjust the CPU/NB voltage (IMC)
  • CPU VDDA Voltage - Default 2.5v. Higher setting 2.695v will stabilize voltages under load but increases temps. Lower setting 2.2v will lower temps.

DIGI+ Power Control & CPU Configuration Warning: Spoiler! (Click to show)
Wiki: The AM3+ Socket offers improved power regulation and power quality specifications, including an increased maximum current support of 145 A versus 110 A.

DIGI+
  • CPU LLC - Adjust CPU LLC. Recommended - Ultra High (75%)
  • CPU/NB LLC - Adjust CPU/NB LLC. Recommended - High (50%)
  • CPU Current Capability - Sets the Maximum Current Support. Recommended 130% for 143A
  • CPU/NB Current Capability - Sets the Maximum Current Support. Recommended 130%
    Note: Raising the Maximum Current Support does not make the CPU draw more Current. It just allows it to scale properly with voltage, to prevent Overvolting. Watts = Volts x Amps
  • CPU Power Phase Control - Sets the Phase Control. Extreme helps stability, but increases thermals
  • CPU Voltage Frequency - More testing required
  • VRM Spread Spectrum - Enabled runs in reduced EMI Mode.
  • CPU Power Duty Control - Extreme gives better stability, but higher thermals. T-Probe tested to 4.7Ghz
  • CPU Power Response Control - Recommended Auto
  • CPU/NB Power Response Control -Recommended Auto
  • CPU Power Thermal Control - 130 Tested to 4.7Ghz (not sure what this effects)

  • DRAM Voltage Frequency - more testing required
  • DRAM Power Phase Control - Extreme gives better stability but higher thermals. Recommend - Optimal

Advanced Tab
  • Cool'n'Quiet - Always Enabled will lower frequency of Cores under load.

  • C1E - Enhanced Halt State. Lowers Power Consumption - Recommend - Disabled while testing Overclock (Enabled - Once fine tuned)
  • SVM - Virtual Machine - Recommend - Disabled unless running Virtual Machines
  • Core C6 State - Effects Overclock. Recommend - Disabled
  • HPC Mode - Recommended - Enabled - Prevents Throttling when Socket Temp gets high. (In some cases it may cause freezing - if this occurs its recommended to disable)
  • Amp Master Mode - Disabled - (Set to Auto once Overclock is fine tuned)

Tricks to Keep things Cool Warning: Spoiler! (Click to show)
Whether you are using a closed loop water cooler or air cooling, here are some trick to lower temps even more.
  • You can use the Stock CPU Cooler fan, with some double sided foam tape and either stick the fan to the case, or stick it to the Close Loop Cooler block, so that it is positioned blowing down over the VRM heatsink. Warning: Spoiler! (Click to show)
  • Another way to lower Socket and VRM Temps is to install a fan behind the motherboard so that it is blowing on CPU Socket. All the components link at the socket, so if you can move heat from it, it will help with overall cooling.

Did you make changes or something?

I started playing with my RAM overclock lately and somehow lost my stable 5 ghz. Personally I think it has to do with touching the DOCP thingy. I might reset CMOS tonight and try to get my 5 ghz back.

Ive saved my 4.5Ghz clock in the bios, i have the ability to save up to 6 i think, i saved my 4.8 clock too but at 1.52v and not yet full prime tested i was reluctant to keep it, might have a play later see what i can hit max then drop it back to 4.5 again, i dont really need it above stock, just thought id get a feel for oc'ing so I can start selling oc systems and be comfortable doing it
post #226 of 4095
I'm sort of old fashioned in not saving the BIOS settings. I kinda wished I did though.

I did make some changes to the guide. Just update the Recommended Settings to have the Power Saving Features disabled as it was creating some confusion with the voltages and frequency fluctuating while stress testing.

No big breakthroughs on how to reach 6.0Ghz or anything like that biggrin.gif
post #228 of 4095
Hello;

Im trying to oc my fx 6300 cpu, now im at 4.7 ghz with 1.404 vcore. Disabled 2 cores to reach highter clocks. Im using recommended settings of Bios. My mb is Asus M5a99x evo R2 and my cooler is Xigmatec Balder SD 1283.

The thing is my cpu core temperature is very near to cpu temp which are 47 celc and 48 celc respectively (under load prime blend test). Sometimes it even passes the cpu temp.

Is it normal or is something wrong? Using Hwmonitor to check temps btw

thks

This is normal. Socket Temps are much lower on 6 and 4 Core FX CPUs, compared to the 8 Core versions. The Socket Temp is more related to the amount of Current Draw the CPU is doing as the Socket is directly linked to the VRMs.

k thks

how much shall i push it in terms of heat? I increased the vcore 1.416 now as it failed in test. Is it safe under 60 celc for my cpu im getting 51 celc core now with this vcore.
