Need Help OC 3800+ X2

Hello, I am already been busy searching the internet about how I OC my CPU. I have read many guides and tutorials but I have still a couple questions.

My specs:
Cooler Master RS-450-ACLY Real Power, 450 Watt
MSI K8N SLI-FI
AMD Athlon X2 Dual core 3800+ 2,0GHz
Thermaltake Blue Orb II
Western Digital Caviar SE16, 250 GB, 7200 rpm, 16 MB, Serial ATA300
TwinMos Memory, 2048 MB, DDR, PC3200, 400 MHz,
XFX GeForce 8800GTS Fatal1ty
BenQ DVP-1650V, ATAPI/E-IDE
BenQ DW1655, ATAPI/E-IDE
2x 120mm (1xledfan)
1x 92mm ledfan

I know only that you must raise the FSB, or HTT for amd for OC'ing. I also know that there are more things that should be changed/tweaked . My question is therefore, what must I change all except the FSB?

This is what I see in my bios:

High Performance Mode......................... Manual
Aggressive Timing............................. Disabled
Dynamic Overclocking.......................... Disabled
Adjust CPU FSB Frequency...................... 200
HT Frequency.................................. 5x
HT Width...................................... 16 16
CPU Spread Spectrum .......................... Disabled
SATA Spread Spectrum.......................... Disabled
PCI-E Spread Spectrum......................... Disabled
PCI-E Clock................................... 100 MHz
SSE/SSE2 Instructions......................... enabled
Cool 'N' Quiet................................ Disabled
Adjust CPU Ratio.............................. StartUp
Adjust CPU Vid................................ StartUp
Extra CPU Voltage............................. By CPU VID
CPU Voltage ....................................1.350V
Memory Voltage................................ AUTO
NF4 Voltage................................... 1.50V

This is the standard setting. I have as a matter of fact a test done with clockgen and orthos. There I got BSOD at 2.5 GHz. These were at 40degrees stressed with vcore of between 1.26V to 1.29V.

Sorry for my crappy english

  1. Any1 that can help me?
  2. Raise Vcore (CPU), Vdimm (RAM), and VNF4 (SBridge) values to achieve better stability.

    then orthos/ stress program :P

    I'm sure the guys here can help you out

    GL

    BTW I don't want you to burn it out mind (eg. don't set the values too high)

    or you won't have a BSOD .... just ... nothing... :P
  3. read the sticky on top of forums
  4. I have but i still had these questions because i dont see exactly the same things in my bios compared to theirs. But what in the list are the Vcore (CPU), Vdimm (RAM)?
  5. Cmon, any1?
  6. Vcore is voltage to the core eg. on a core 2 duo e6600 the max voltage at stock is ~1.35v

    1.6v max on h20, 1.4ish on air

    YES! You are right! Vdimm is memory voltage; increasing this will probably allow less stability issues when ram is clocked high/ tight timings. Generally 2.2v max on naked ram chips, 2.4v max on heatspeader + active fan cooling (eg 80mm fan above them).
  7. Can you post some CPU-Z readings for your oc'd system?
  8. i'm using the same CPU
  9. I dont think you understand my question.

    What in the list below are the Vcore and wich is the Vdimm?

    High Performance Mode......................... Manual
    Aggressive Timing............................. Disabled
    Dynamic Overclocking.......................... Disabled
    Adjust CPU FSB Frequency...................... 200
    HT Frequency.................................. 5x
    HT Width...................................... 16 16
    CPU Spread Spectrum .......................... Disabled
    SATA Spread Spectrum.......................... Disabled
    PCI-E Spread Spectrum......................... Disabled
    PCI-E Clock................................... 100 MHz
    SSE/SSE2 Instructions......................... enabled
    Cool 'N' Quiet................................ Disabled
    Adjust CPU Ratio.............................. StartUp
    Adjust CPU Vid................................ StartUp
    Extra CPU Voltage............................. By CPU VID
    CPU Voltage ....................................1.350V
    Memory Voltage................................ AUTO
    NF4 Voltage................................... 1.50V
  10. Vcore = CPU Voltage in your list
    Vdimm = Memory Voltage
  11. Well, the problem is, that I cant change CPU Voltage, its not selectable :( But i can change Extra CPU voltage to 3.3%, 6.6% etc etc.
