Asus K8v Se Deluxe + Twinx1024-3200xl


Recommended Posts

Hi RamGuy,


I just set up a new gaming rig, the components are as follows:


MOBO: Asus K8V SE Deluxe

BIOS: Version 1005 beta (08.00.09)

CPU: AMD Athlon 3200+ (Newcastle) -- OC'd to 2.41 GHz

CPU COOL: AMD Stock Fan & Heatsink air-cooled

RAM: Corsair TWINX1024-3200XL (2-2-2-5) -- Slots 1 & 3

GFX: BFG-Tech Nvidia 6800 GT OC

OC'd to 400MHz Core & 1100 MHz Memory

GFX COOL: Arctic Cooling NV Silencer 5 GPU Cooler (air-cooling)

GFX Driver: Nvidia Forceware Version 6702-beta

PSU: Vantec Stealth 520W



Could you tell me what would be the optimal mobo bios setting for this rig?

These are my current settings:


HT Frequency: 800MHz

HT Data width (upstream): 16 Bit

HT Data width (downstream): 16 Bit


Memlock Mode: Auto (all memory settings are set to auto)

Performance Mode: Turbo


ECC Config: Should I keep it disabled?


CPU FSB Frequency: 219MHz


CPU Voltage: 1.500V

DDR Voltage: 2.8V

AGP Voltage: 1.5V

V-Link Voltage: 2.5V


As far as Memlock to CPU Ratio settings are concerned, I tried both 1:1 (DDR200) and 2:1 (DDR400) with Memlock Mode set to Limit. The 1:1 (DDR200) setting worked fine but the 2:1 (DDR400) setting did have a few reboot occurences depending on what I was running at the time. There are also the other settings such as 4:3 (DDR266), and 3:2 which I haven't experimented with as of yet.


So far, with all Bios settings for RAM set to auto, everything works fine and is running really fast. Doom III (all setting set to max) works prefectly without BSOD, reboot probs, or FPS drops -- so far.


There are also the ECC bios settings which seem to include settings that might have to do with the CPU Cache?? I'm not exactly sure, but any suggestions here would help! Let me know if you need the exact bios settings... if you need them.


My main question is... should I leave all the memory settings on auto, or should I manually set them? If so, what settings would you suggest for optimal performance? What other options in the Bios could I experiment with to make this rig faster?


Also, it seems that the AMD Athlon 64's are highly un-overclockable compared to the current Pentiums... I've got my Athlon 64 running stable at barely 10% above at 2.41GHz, anything beyond that and its an automatic reboot --attempt denied! Do you think it would be worth looking into alternative cooling options to OC anymore? I'm currently running the Stock block and fan... and I have a feeling that the proc might not be able to push much more -- economically.


I've stuck with Corsair for the last three systems I've built... and never had any problems. You guys are second to none! Your recommendations and suggestions would be highly appreciated!

With this MB I would suggest you set the Rass to Cass to "3" so I would set these timings and then set the Dim Voltage to +2.8 Volts:

CAS Latency CL=2.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 11

Row Precharge Time tRP 2

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default

Enable 2T Timing Disabled

Then test the system with http://www.memtest.org and make sure it's stable! If you have problems, I would set Enable 2T Timings to AUTO and test it again!
