Hello all! I have a DFI LanpartyUT nF4 Ultra-D with an AMD Athlon 64 3000+ Venice 90nm and 2X1GB OCZ Performance PC3200 1GB DDR400 CL3 3-3-8 (dual channel) i'm trying to overclock. I'm still fairly inexperienced in this, my first overclock was my old athlon 2500+ that I got up to 2.3 successfully. But this seems a little more complicated.

I've been reading around and played with my bios a bit(latest flashed) and so far I got up to 2.34 GHz. Detailed info:

Core speed: 2340.3 MHz
Multiplier: x9.0
HTT: 260.0 MHz

FSB Bus - 260
LDT/FSB Ratio - Auto
CPU/FSB Freq ratio -9.0
CPU Vid Startup - 1.475
CPU Vid Control - 1.450
CPU Vid Special Control - auto
LDT Volt - 1.30v
Chipset Volt - 1.60v
DRAM Volt -2.80v

DRAM Frequency: 166 (5/06)
CPC : Disabled
Tcl: 3.0
Trcd: 04
Tras: 09
Trp: 04
Trc: 12
Trfc: 15
Trrd: 05
Twr: 03
Twtr: 02
Trwt: 04
Tref: 3120
Twcl: auto
Dram bank interleave: enabled
Dynamic Skew ctrl: auto
Skew Value: 0
DRAM drive strength: lvl 3
Dram Data drive strength: Auto
Max Async: 07
Dram Response time: normal
Read Preamble: 05
IdleCycle Limit: 32
Dynamic Counter: auto
R/W Queue Bypass: 02x
Bypass Max: 02x
32bit granualarity: enabled(2bursts)


I'd be happy if I can get this up to 2.6-2.7 or so. Thanks a lot in advance, any help would be greatly appreciated ! =) Oh and Happy New Year!

You can probably lower your vcore (i have mine at 1.35v 2.4ghz atm), and set your LDT/FSB to 3x. Those jumped out at me at a quick glance. Did you read the overclocking stickies and all that good stuff? Oh, your power supply is under spec as well... there's a sticky on that also.

LDT/FSB is automatic so it will know its x3, so it makes no difference to change it.

I can get it up to 2.4something, but thats if I reduce my Dram frequency to 166(5/06) and get worse scores in 3dmark than when I had it at 2.3 and 180mhz(ram). I tried incorporating some of settings from the "NF4 Settings/Help (by RGone)" post and managed to get into windows at 2.4 with 180mhz, but it was pretty unstable. I've tried a number of different settings but unfortunately had very little success. Could this just be because I have a 450w antec psu? Thanks.

Update: I'm up to 2.5 now using 280x9x and 150 (03/04) DRAM frequency. My timings are 2.5-4-3-7. Trc:12clocks and Dram idle timer is 256. All else is set on auto/default, using the 704-2bt bios. What i'm having a hard time understanding is how my 3dmark05 scores are actually lower. I'm a gamer, and the main reason i'm oc'ing is to get better performance in games. What's going on?

Update: Thanks to a buddy, i'm up to 325*8, LDT/FSB is 3, and ram frequency is 2/3. Bank interleave is disabled, timings are 2.5-4-3-7
TRC - 11
TRF - 13
TRRD - 04
TWR - 03
TWTR - 02
TRWT - 04
TREF - 3120
32bit granularity - 4bursts
bypass max - 16x

The rest of the settings are auto/default.


I got up as high as 337*8, but instability kicked in. So far prime is stable at the current settings (2.60), was wondering if theres any settings I can modify to improve performance and possibly help me push it a little more. Thanks!

Don't know buddy but it's a DH-E6 90nm.

Note: 290*9.0 with LDT at 4.0 also seems to work (2.61) CPU/11 membus:237mhz but that pushes the HTT over 1k, and as I understand it, ti should be around or lower. Still experimenting though, not sure what to stick with yet and still confused about 3dmark scores.

Okay here is my current setup:

325*8.0 (2.60ghz)
LDT - x3.0
LDT Bus Transfer Width - (down)16 (up^)16

Voltages:

CPU VID Startup Value - 1.525v
CPU VID Control - 1.500v
LDT Voltage - 1.30v
CHIPSET Voltage - 1.60v
DRAM Voltage - 2.90v
DRAM + .03v if its not 3.2v - DISABLE
(haven't tried lowering voltages yet)

RAM settings:
DRAM Frequency - 150RAM/FSB: 03/04
CPC - Enabled
TCL - 2.5
TRCD - 04
TRAS - 07
TRP - 03
TRC - 11
TRFC - 15
TRRD -03
TWR - 03
TWTR - 02
TRWT - 03
TREF - 4128

DRAM Bank interleave - Enabled
DQS Skew Control - AUTO
DQS Skew Value - 0
DRAM Drive Strength - AUTO
DRAM Data Drive Strength - AUTO
MAX Async - AUTO
DRAM Response Time - FAST
Read Preamble time - AUTO
IDLE Cycle limit - 256 cycles
Dynamic Counter - DISABLE
R/W Queue Bypass - 16x
Bypass Max - 04x
32 byte Granularity - DISABLE (4 bursts)


Not sure if I can push the CPU further to 2.7, but now I don't really care as I doubt there will be a significant performance boost. Right now I just want to know if there is anything I should change in the above settings and why exactly is my 3dmark05 score low but my ram/cpu benches are high (sandra and everest). Thank you.

I changed it around a little and used the following settings:

325*8 (2.6)
216mhz ram CPU/12

CPU startup vid - 1.425
CPU vid - 1.425
CPU vid special control - 110%

CPC - Enabled
TCL - 2.5
TRCD - 04
TRAS - 07
TRP - 04
TRC - 11
TRFC - 13
TRRD -05
TWR - 03
TWTR - 02
TRTW - 05
TREF - 3120

Bank interleave - disabled

DQS Skew Control - INCREASE
DRAM Drive strength - Auto
Dram data drive strength - 3
Max async latency - 7x
Read preamble - 5x
Idle cycle - 256
Dynamic counter - disabled
R/W Que Bypass - 16x
Bypass Max -7x
32 byte granularity - disable 4 bursts

Now i'm getting 7507 in 3dmark05 and 4446 in PCmark05 but my 'chipset' temp is also up to 54C under load (Cpu is fine though). So obviously i'm getting a lot more now than I did before. Anyway to increase this further? I'll continue to experiment.
