Temps and overclocking phenom II x6 1090t

Hey all,

This is my 1st venture into overclocking and I have just overclocked my 1090t to 3.7 ghz by only raising the cpu multiplier to 17.5 and am running prime95 on my pc. Therefore everything else is stock - cpu frequency at 200, pcie frequency at 100 and cpu voltage at 1.325v
Also as you can see in my signature, i am using a noctua d14 and the noctua thermal compound. The weird thing is, my temps right now on Hwmonitor and speedfan are showing temps of around 52-53 degrees celcius during prime 95 stress test. Further to that, my 4gb of corsair xms3 dhx 1333mhz which were running at 7 cas latency has just dropped to 6. How is this possible when i did not edit the NB frequency multiplier which is at stock of 10.0 2000mhz.

My computer has also just shut down during the stress test. I believe this may be due to the heat and also the low voltage.

Pls advise. Thanks

  1. increase your Vcore
    go down RAM ratio from 3:10 to 3:8 (can get max CAS & Timming Memory, Low Latency) & Don't forget increase Vdim to Max 1.65 & Also check your temp under 62*C don't over this
  2. Thanks for the advice...i will do that now...btw my processor was increase to 3.5 not 3.7 sorry 200 *17.5
  3. it. s ok this OC simple can do it! try increase Multiplier
  4. I can't seem to an option to change my ram ratio. Also , just to check, Vdim is memory voltage, correct? My motherboard calls it dram voltage. Is it the same one?
  5. yes Dram voltage same VDIM .. n your mobo is.. ???
  6. How do i change my ram ratio?
  7. what is product your Motherboard...? general in RAM seting : set auto to Manual change PC1066
  8. My board is an Asrock 890gx extreme 3. My ram voltage is set to auto which is 1.5v. According to bios, my ram is running at dram frequency of 800 which is 1600. However it's only a 1333 ram...i don't understand why
  9. open in memory configuration yes .. change 1066
    increase Voltage Ram don't auto remeber over limit RAM VOLTAGE 1.65V
  10. why change to 533hz - 1066 and not 1333 - 667mhz??
  11. yes right . it can give you more than 667 may untill 733mhz if FSB increase more 200
    or just Set 1333 Set timming to 9-9-9-27 it can get 4Ghz or more with increase Muliplier
    when you get 3.8Ghz
    CPU COnfiguration : Cool n Quiet Disabled position
    Smart Fan Disabled too
  12. I have set it to 1333 and cas is back to 9-9-9-25
    I'm currently at 3.4ghz and running prime but temperatures are now showing 58 degrees celcius which doesn't make sense seeing as i have a noctua d14
  13. it's problem with your cooler , check again if your Noctua Use 1 Fan Add 1 again & replace new Thermal Paste use good Thermal like Artic Mx5, A ceramique, etc . clean your HSF with Alcohol Add fan for exhaust min 80mm , very importan keep temp CPU under 60C (temp1) (temp2: 80C) temp3 (80)C HDD 47C for healthy & Stabillity
    DISABLED SMART FAN !
  14. I have just cleaned and applied fresh noctua nt h1 thermal paste to the cooler. The d14 is setup with 2 Xigmatek XLF-F1253 in push pull configuration. My case is a aluminium lian li pc 7fnw with 2 intakes and 1 exhaust.
  15. ok... no problem just Check CPU must Under 60* when streess test Fullload 60*C & another temp OK, overheating can damage harware... just it up up up
    if wan't more clock increase multiplier step by step & Next use 2 Fan for Noctua min fan 2000 RPM, (2 intakes and 1 exhaust.) this must modificati 2exhaust 1intake let case open , how much Drop your Temp CPU
  16. My pc can't even last for 15 mins in prime at 3.5ghz and a vcore of 1.4. Another weird thing is, cpu-z is showing my vcore to be at 1.520 during the stress test

    The motherboard is most likely compensating for the processor being under full load. I think thats called load line calibration?
  18. If your theory is right then isn't 1.52v over compensating?
    That is almost close to the max voltage allowed by the board for only an increase in 0.3ghz
  19. I always thought that it might be a compensation settings in the BIOS but I could be wrong
  20. Vcorer in CPU-Z 1.44 for 3.8 Ghz n 1.52 for 4Ghz maybe your software not accurate check in Bios how much Vcore . it's simple OC from default just change Manual increase Multiplier ! ....don't increase Vcore during your Oc NOT BSOD YET!
  21. A little tips:

    1- Set the specifications for your RAM manually in the BIOS, don't use AUTO configuration
    2- Disable C1E support
    3- Disable Core performance boot
    4- Set the NB to 3000MHz with 1.1V-1.2V, you need find the correct voltage here
    5- Set the HT link to 2000MHz
    6- You also need change the CPU/NB voltage, you also need find the correct voltage here.
  22. thanks for your tips. I will try that.
    However can anyone advice on my temps. My pc either freezes and temps reading on hwmonitor are at 60 or the pc would just shut off.
  23. Be sure that your cooler is properly installed and the fans are running. i'd remove the cooler, clean it with alcohol and install it again. The same with the CPU.
  24. Before i started overclocking, I have cleaned the noctua d14 and my cpu with thermal remover and purifier.
    Btw are you sure to set NB to 3000mhz, when i did that, my com could not even start. I had to clear cmos to allow it to start.
    My vcore in bios during stock is 1.32 and is correctly reflected in cpuz and hwmonitor. However when i overclock it to 17*200 = 3.4ghz, and set my vcore to 1.4, my vcore shown in bios will exceed 1.42 and this will also be reflected in cpuz and hwmonitor. And during stress, it will show 1.5
    Am i missing something here?

    Do you mind explaining the NB, Ht link and CPU/NB to me? Is Ht link affected by NB? As Ht link cannot go higher than NB.

    On what overclocked settings should i set to qualify for an NB of 3000mhz?

    Just to get the terminology right.
    NB = NB frequency multiplier
    HT link = HT bus speed
    CPU/NB voltage = HT link voltage? or mGPU voltage

    Pls correct me if i'm wrong

    What is Ht Bus width? i have 3 options for these: Auto, 8 bit and 16 bit. Should i leave it at auto?
  26. Hi sorry for the late response.

    1.4V for 3.4GHz is insane, with 1.4V you can run the CPU @ 4GHz. In my case, I can get the 3.7GHz with the stock voltage, so, maybe you can get the same settings.

    Pretty sure about the NB@3000MHz, and you rig can't boot for a simple reason: you also need rise the NB volts and NB/CPU volts. How much? That depends of the mobo, i set the NB volts to 1.12V and CPU/NB volts to 1.375 (I don't remember now) but my mobo is a Gigabyte 890FXA-UD5, so, the things can be different in you mobo.

    1- NB: The northbridge is one of the two chips in the core logic chipset on a PC motherboard, the other being the southbridge, the NB typically handles communications among the CPU, RAM, BIOS ROM, and PCI Express (or AGP) video cards, and the southbridge. Full info

    2- HT:
    Quote:
    HyperTransport™ Technology is a high-speed, low latency, point-to-point link designed to increase the communication speed between integrated circuits in computers, servers, embedded systems, and networking and telecommunications equipment up to 48 times faster than some existing technologies.

    HyperTransport Technology helps reduce the number of buses in a system, which can reduce system bottlenecks and enable today's faster microprocessors to use system memory more efficiently in high-end multiprocessor systems.
    Full article

    3- CPU/NB: This's the voltage to the IMC (Internal Memory Controller) in the CPU, while the NB in on the mobo.

    4- HT and NB are linked on Auto,so, if you rise one the other rise too. The best HT speed is 2000MHZ, so, set the 2000MHz manually and rise the NB independent to 3000MHz. The mobo set the HT below or equal to the NB for avoid problems,so, you are right HT can't go higher that NB.

    5- The NB can set in overclock or stock, overclock means 3.2GHz to 3.3GHz or above.

    6- NB = NB frequency multiplier, you are right.
    HT link = HT bus speed, you are right.
    CPU/NB voltage = HT link voltage? or mGPU voltage. No, check the post above, this's the voltage to the MIC in the CPU.

    7- Don't change the HT Bus Width, set to Auto.

    Again, sorry for the late reply and excuse me for my bad English.
  27. Thanks for the reply mate. And you weren't late. I just posted it today. =)

    I'm still confused for the setting on nb voltage and cpu/nb voltage
    In my bios,
    Nb frequency multiplier option is directly above Nb voltage option. Therefore am i right to assume that if i increase my NB frequency multiplier, i would need to adjust the NB voltage? Or should i adjust the mgpu voltage?
    There is no option for cpu/nb voltage in my bios. Which option can it be?
  28. Ok.

    I had to read the manual of your mobo and I can't see any CPU/NB option as you say.

    Don't touch the mGPU voltage unless that you want kill the onboard video of your mobo.

    Rise the NB to 3000MHz and the NB volts should be something between 1.1V and 1.2V nothing above that, you need start to play with little increase until you get it stable.

    Contact to ASRock support and ask they for the CPU/NB option, I don't see any option with the same purpose.
