I wouldn't say your chip is a dud although 1.46 does seem a bit high for a 4.5 clock. Which CPU do you have again?? It would help if you could put your system into your profile. It's possible that if you up the CPU_NB a bit you may be able to lower the V_COre. You mauy be over compensating for some instability from the IMC.

I updated my profile with my configuration. Any help is much appreciated. I can actually run the first test (small FFT's) in prime95 for much longer with 1.38 but anything under 1.46 has an error in the first minute from worked #6.

It's you IMC that's giving you fits I'm certain of that try it at 1.3v with the CPU at 1.4

Hello. I recently started OCing my FX-8350 and was looking for few tips and tricks, as well as few clarifications if that's ok. First off, the setup:
  • AMD FX-8350
  • ASUS Sabertooth 990FX R2.0
  • 2x 8GB Kingston HyperX Beast @ 1600MHz
  • Seasonic SS-760XP2
  • be quiet! DARK ROCK PRO 3
  • Super Flower SF-2000B-BK

So far, I have it running quite stable (full stability should be verified by the time I get back from work and 24h Prime95 finishes, followed by 12h IBT Maximum) at 4.5GHz and 1.4125V Vcore. OC was regular multiplier + Vcore OC, and DIGI+ settings are standard Very High/130 setup that I found to be recommended for this MB. Peak temperatures that I had were 55.6°C for CPU core and 61°C for CPU socket (not counting those 255°C derps from sensor), which causes the cooler to kick in to 100% and quickly bring them down 47°C/52°C. Tests completed so far include 9h Prime95 with custom blend, 2h Prime95 burn test, IBT Standard, High, and Very high @ 10 iterations each, and single iteration of IBT Maximum. None of them failed so far, but I did notice that one of the cores was lagging behind when it comes to Prime95 blends due to privileged processes that ran on that core (source: Process Explorer, most likely culprit: HWiNFO Sensors + logging); it's always a different core, so I doubt that one is actually derping.

All right, boring status report done, now to ask a question or two. I plan to go for 4.7GHz, but seeing how my temperatures are already getting quite close to 60°C/70°C thermal limit, I'm starting to question that goal. Do you think I might be able to squeeze in 200 extra MHz without going over the thermal limit (if MB doesn't shut me down, I forced a hard limit manually in HWiNFO Sensors)? 100MHz? Is my Vcore a bit too high? I tried 1.4V, but Prime95 failed on core 3 after 3 hours with a rounding error. Will try 1.40625 for weekend. Will it be worth it? Also, there are two more issues that I could use some help with. The first one is related to Vcore and VID voltages. I could not find settings in BIOS that mention VID in any direct way. While I set my Vcore to 1.4125V, VID (as indicated by HWiNFO Sensors and AMD Overdrive) stays locked to 1.3625V. I tried changing it from Overdrive to match Vcore, but every time I reboot, it reverts back to 1.3625V (using either Manual or D.O.C.P. as AI profile). Any clues as to how to handle this? The second one is most certainly MB related and I should probably ask it in the right thread: what the hell does Temp8, picked up from ASUS EC in HWiNFO Sensors and HWMonitor, actually measure? It is usually few degrees lower than CPU Socket, but I have no idea what it actually measures so I don't know how to set emergency shutdown temperature for it. Any hints?


EDIT:
Forgot to mention that I didn't touch my NB settings and it's running 2200MHZ @ 1.1375V.

If it's spring now and room temps rise so do you PC temps. then say you try to re-encode some video or some other heavy workload then yes those temps are too high and you may want to consider dropping the OC to 4.4 so you can lower your voltage and heat.

I'll have to do some fiddling and see if i can lower the voltage, atm i have 1.25 set on the cpu_nb and 1.46 on the cpu. I monitored the temps a bit with some light activities e.g. gaming and the temps never went past 40. I should try and do some recorded benchmarks and see the differences between 3.5, 4 and 4.5 . Guess the chip is a dud? should i try and get another one ?
Your chip isn't a dud. I would ultimately point a finger at your cooling. You are right where I would put you for a really good high quality single tower. 4.5GHz. You would need a dual tower or closed loop to really go any further.

Ok I can't answer all your questions especially those related to your mobo since I don't own a Saberkitty. But here I go.

1. Max core temp of FX is 70C. Since you have a Be Quiet cooler why not just leave your fans at 100%. That will give you plenty headroom with minimal noise I am sure. Based on using 100% fans you still have a good 23C of room on the core and 28C on the socket. Now with that in mind you have lots of head room. If you want to bring the temps down a little bit. Strap the stock heatsink fan to your VRM heatsink and a 120mm fan to the back of your motherboard around the socket area. These will net you the best results. You should be able to reach 4.7Ghz on that cooler. Priming and IBT produce A LOT more heat then what your CPU would normally produce. So set your fans to 100% fixed when Priming and IBT'ing. Once you have verified stability you can put them back into PWM mode.

2. Your VID is an indication on what your CPU's stock voltage SHOULD be. It is usually shown by third party software like HW Info and AIDA 64. Usually the VID value can give you an idea on how your chip will OC. (Similar to AISC value in GPU-Z) Your VID should not change when you change your Vcore. At least that is how I understand it. If you want to check your Vcore use CPU-Z ore check the Vcore section for your CPU in HW Info.

3. I dunno don't use Saberkitteh!

  • 2x 8GB Kingston HyperX Beast @ 1600MHz
  • Seasonic SS-760XP2
  • be quiet! DARK ROCK PRO 3
  • Super Flower SF-2000B-BK





The VID will not change, or should not. Yours is kinda' high, mine is high at 1.350. You could set the NB to 1.25 with out much trouble. I have he LLC set to high as utla high created too much heat and now I am cool and stable at least with IBT and an hour or so of prime95. The Sabertooth overclocks the same as my CHVFZ.

1. Max core temp of FX is 70C. Since you have a Be Quiet cooler why not just leave your fans at 100%. That will give you plenty headroom with minimal noise I am sure. Based on using 100% fans you still have a good 23C of room on the core and 28C on the socket. Now with that in mind you have lots of head room. If you want to bring the temps down a little bit. Strap the stock heatsink fan to your VRM heatsink and a 120mm fan to the back of your motherboard around the socket area. These will net you the best results. You should be able to reach 4.7Ghz on that cooler. Priming and IBT produce A LOT more heat then what your CPU would normally produce. So set your fans to 100% fixed when Priming and IBT'ing. Once you have verified stability you can put them back into PWM mode.

2. Your VID is an indication on what your CPU's stock voltage SHOULD be. It is usually shown by third party software like HW Info and AIDA 64. Usually the VID value can give you an idea on how your chip will OC. (Similar to AISC value in GPU-Z) Your VID should not change when you change your Vcore. At least that is how I understand it. If you want to check your Vcore use CPU-Z ore check the Vcore section for your CPU in HW Info.

3. I dunno don't use Saberkitteh!

  • 2x 8GB Kingston HyperX Beast @ 1600MHz
  • Seasonic SS-760XP2

So far, I have it running quite stable (full stability should be verified by the time I get back from work and 24h Prime95 finishes, followed by 12h IBT Maximum) at 4.5GHz and 1.4125V Vcore. OC was regular multiplier + Vcore OC, and DIGI+ settings are standard Very High/130 setup that I found to be recommended for this MB. Peak temperatures that I had were 55.6°C for CPU core and 61°C for CPU socket (not counting those 255°C derps from sensor), which causes the cooler to kick in to 100% and quickly bring them down 47°C/52°C. Tests completed so far include 9h Prime95 with custom blend, 2h Prime95 burn test, IBT Standard, High, and Very high @ 10 iterations each, and single iteration of IBT Maximum. None of them failed so far, but I did notice that one of the cores was lagging behind when it comes to Prime95 blends due to privileged processes that ran on that core (source: Process Explorer, most likely culprit: HWiNFO Sensors + logging); it's always a different core, so I doubt that one is actually derping.

All right, boring status report done, now to ask a question or two. I plan to go for 4.7GHz, but seeing how my temperatures are already getting quite close to 60°C/70°C thermal limit, I'm starting to question that goal. Do you think I might be able to squeeze in 200 extra MHz without going over the thermal limit (if MB doesn't shut me down, I forced a hard limit manually in HWiNFO Sensors)? 100MHz? Is my Vcore a bit too high? I tried 1.4V, but Prime95 failed on core 3 after 3 hours with a rounding error. Will try 1.40625 for weekend. Will it be worth it? Also, there are two more issues that I could use some help with. The first one is related to Vcore and VID voltages. I could not find settings in BIOS that mention VID in any direct way. While I set my Vcore to 1.4125V, VID (as indicated by HWiNFO Sensors and AMD Overdrive) stays locked to 1.3625V. I tried changing it from Overdrive to match Vcore, but every time I reboot, it reverts back to 1.3625V (using either Manual or D.O.C.P. as AI profile). Any clues as to how to handle this? The second one is most certainly MB related and I should probably ask it in the right thread: what the hell does Temp8, picked up from ASUS EC in HWiNFO Sensors and HWMonitor, actually measure? It is usually few degrees lower than CPU Socket, but I have no idea what it actually measures so I don't know how to set emergency shutdown temperature for it. Any hints?


EDIT:
Forgot to mention that I didn't touch my NB settings and it's running 2200MHZ @ 1.1375V.

VID, as mentioned above, doesn't change.

Extra 200 MHz to squeeze out is a question of many possibilities.

While a lot of things has already been said to stabilize the OC, that should serve as your guide. VRMs, socket temps, etc. But the following would still require your own experiment to find out.

Voltage wall will be one. Its how much that 200 MHz would require from the Vcore.

Temp is another one. Can your cooler keep up?

You can only find out the answer once you start digging in..

my VID in HWINFO64 is what my BIOS has the voltage set to... it changes with the associated value in BIOS settings...i assumed this was to see how much vdroop you are experiencing and compensate accordingly?

VID or Voltage Identification Digital, is a chip registered value.

It could be said to be equal to Vcore only at stock settings. No turbo core or vboost anything.

Be sure you are reading the right one. VID does not change unless done on AOD manually. But remember, AOD values get released on reboot.
