DFI NFR SLI-DR Expert – Overclocked 3D benchmark performance + SLI verification

3DMark 2001 and Aquamark3


Click to enlarge.

The tests above were run with the 7800GTX, 4000+ San Diego and 2x256MB Corsair 3200LL BH-5(3.6V) aboard. The tighter timings and higher bandwidth of the BH-5 produced higher scores in both of these bandwidth dependant synthetic gaming benchmarks. Aquamark3 allowed a higher stable overall CPU and Memory bench speed and it was repeatable, whereas 3DMark 2001 necessitated a slightly lower FSB (320 vs. 325) to produce stable and repeatable benchmarks.

Our SLI verification tests again utilized the 4000+ San Diego. Comparison tests were done to determine what combination of memory and divider would consistently produce the highest scores. The highest stable and benchmark repeatable CPU speed was 2880Mhz. BH-5 modules at the 166 divider (261 MHz) were evaluated against TCCD modules at the 180 divider (288Mhz), and scores were consistently higher with the TCCD. 2x512MB Corsair 3200XL modules (2.96V) that were used along with a pair of NVIDIA 6800 Ultra’s.

    Another well done review Sir.

    If you had to pick one, which one would you pick? A8N32-SLI or Expert? Please don't tell me "Both are good", "They're different animals" or anything in that sense. Most of us have to pick ONE and that exact question is what we want to know. I'd venture to say what matters are following two:

    1. Overclockability
    2. Stability

    Fetures, layouts, etc... yeah.. they are all good and nice, but what really matters are whether the overclock is stable. And that's what brought DFI here today. Could you comment on it? If you had a choice to pick JUST ONE, which one would you pick?

    Great review anyway. I'm actually happy that AT is becoming more enthusiast-friendly and looking forward to the next review. (Possibly Opteron Overclocking review?)

    Thanks.

    Hi Lop:)

    I'll be honest in telling you I have not had my hands on the Asus board to know it's full overclocking abilities, so I really can't give you an opinion on which board to choose. Wesley could give you full insight on that one.

    I go way back in the overclocking business, having hooked up with my best buds OPPAINTER and DDTUNG back in the day. At that time we were modding and overclocking each generation of Abit AMD based boards starting with the KG7 and culminating with the NF7-S, which we were pre-production testing prior to it's retail release. I've also had a play with Epox, Gigabyte, and the famous Shuttle A64 board.When I recieved the original SLI-D back in January it was an overclockers dream come true.All the voltage and overclocking/memory options and it overclocked way easy compared to the norm.(Thank you Oskar Wu:))

    The Expert is more of the same but much better. I am a bit biased on a personal level about the board, and if you had just asked about it, I'd have given a thumbs up.

    Thanks for your comments !

    Does this use the same chipset as the A8N32-SLI? If not, why not, and where are the competitors for that board?

    how come the box the reviewer received already has that "anandtech gold medal" sticker on there? hmmm, kinda fishy... LOL

    Under the extreme oc page, the pic showing the HTT @ 400MHz and RAM @ 300MHZ 2.5-3-3-8 but the sisoft is only 6674 MB/s? 300MHz should be displaying something near 8GB/s
  • RSica - Sunday, November 27, 2005 - link

    That would be true if not running at 2400Mhz.All HTT and Memory overclocking tests were done at a reduced multiplier. Each multiplier also has an effect on system bandwidth in the way the A64 responds to them.If I had chosen to run 7 and a total CPU Mhz of 2800, you would have most likely seen the 8000mb/s figure.

    In contrast, the stock 4000+ at 12x200Mhz with tight timings will average 5600-5700mb/s.
    Another consideration is that with the bios used which made it more ram overclocking friendly, that there was possibly a relaxation of some of the bios register settings, which can also reduce bandwidth a bit in the name of pushing the memory higher in Mhz.

    Thanks for your comments !

    What i'm really interested in is if this board suffers from the same problem as my Ultra-D with PC4000 VX memory (the infamous cold boot issue)?

    I don't really want to pick this board up and have it suffer from the same problem. Not that i've tried my VX with the latest beta bios, but that's besides the point.
  • RobFDB - Tuesday, November 29, 2005 - link

    Can anyone confirm or deny that the cold boot issue exists with this board?
  • yacoub - Saturday, November 26, 2005 - link

    If it had passive cooling like the A8N32-SLI I'd be more interested.
