Test Setup and Overclocking

Test Setup:

  • AMD Athlon64 3000+ Newcastle
  • Abit NF8
  • Abit KV8 Pro
  • DFI LANParty UT nF3 250Gb
  • Asus K8N-E
  • 2 x 512MB Centon Low Latency PC3200 2-2-2-5
  • ATI Radeon X800 Pro
  • Nvidia unified platform drivers 5.10
  • VIA Hyperion v455
  • ATI Catalyst 5.1
  • Hitachi 80GB SATA


The NF8 provided not the best overclocking results, but good enough for 24/7 usage.  I proceeded to find the highest HTT allowed with both single and dual sticks of memory installed.  The first test will be conducted with the memory divider at 1:1.  The second test will be with a divider, so that the RAM wouldn't pose as a bottleneck.  All memory timings were left at 3-4-4-8 2T and the LDT multiplier at 1x.  I made sure that nothing would bottleneck the chipset potential.  The reason why I tested with two sticks of memory is because most systems today makes good use of 1GB or more.  Running 512MB can get a little slow at times, especially during game loads.

  • Highest overclock 1:1 single stick:  270HTT
  • Highest overclock 1:1 dual stick:  265HTT
  • Highest overclock with divider single stick:  270HTT
  • Highest overclock with divider dual stick:  270HTT

The results on the NF8 were very interesting.  I seemed to hit a dead wall at 270HTT no matter what I did.  Personally, I feel that the BIOS hasn't released the board's full potential.  Unlike the usual instability of errors and random restarts, 270HTT was a dead ceiling.  Going up slightly higher resulted in a no POST.  This board is still new so Abit may release newer BIOS updates to fix this.  Let's just hope that they do.

Overclocking Update:

After spending some extra time with the motherboard with the newest BIOS 15, the board reached a new record in overclocking.  With two sticks of memory installed and running a divider, the Abit NF8 reached a beautiful 320HTT.  That's certainly very impressive.  For those who have yet to update to the new BIOS 15, please do so NOW.  You're missing out on some great overclocking headroom.

  • New highest overclock with BIOS 15 with divider dual stick:  320HTT

The NF8 wasn't a big challenge against the DFI LANParty UT nF3 250Gb in the overclocking department, but now with the new BIOS, it is.
