The Asus board redeems itself at overclocking the Presler (Pentium D 950), considering its workstation based limitations at overclocking the 840EE. At these settings, the system was able to complete all of our benchmark test suites three consecutive times and also run Prime95 and SuperPI without issue. We were unable to overclock the FSB past 305 due to board limitations, but we were able to boot into WinXP at 4.80GHz on air cooling while reaching 5.00GHz at post. The performance of the Presler is exceptional for an Intel based system. The benchmark results shown were attained at the FSB settings that offered the highest scores. We will be exploring Presler's full capabilities in a future article.

    Workstation /= server...

    Overclocking isnt wacky in the worstation world at all. Picture a guy using 3dsmax everyday in his personal studio, or rendering TV streams in Maya, or doing texture work, or compiling source codes at a game studio...

    Overclocking in the Workstation market is probably ALOT more common than people would think. Take overclocking that Pressler. That big of an overclock could mean whole DAYS of extra time per year that the CPU would have otherwise been spending cranking away on rendering. Thats a serious gain.

    I dont think many serious servers will find a board like this one in em, to boot. Its lacking alot of features that a serious server hosting lots of users would deffinitly feel the need for... like built in SCSI, multi cpu support, RAM support over 8gig/4slot, etc.

    On the other hand, this is a near perfect workstation board. High clocked RAM support for both ECC and non ECC. Non buffered memory. Both SLI and Crossfire support at 8x/8x. Plenty of SATA II plugs for cheap storage.

    I took notice of the OC results and settings, and i like what i saw. :)

    That was a reply to the poster one level up, sorry. :D

    Thanks for taking the time to do the OC tests, however. Some people out there did like to see em.

    If those 4.8ghz air overclocks are normal intel won't have to wait for conroe to take back enthusiasts crown. That's amazing.
  • Leper Messiah - Tuesday, December 6, 2005 - link

    Hell yeah. 4.8GHz on air with Dual core is a 20% over what an 840EE will do. And I bet that with nF4 and a DFI 5.0+ is possible. oooh. Sexay.

    Yeah, I'm wondering if the Pentium D 920 might become a new "favourite" chip for them to play with :)

    Talking about Conroe, isn't the 975X supposed to support upgradability to it
  • xtremejack - Tuesday, December 6, 2005 - link

    If you look at the chipset price guides for this month by Anand, 975x will not support Conroe
  • Gary Key - Tuesday, December 6, 2005 - link

    Intel has not officially confirmed either way on the 975X to Conroe path. We have heard both a positive and negative on this but from different sources. As soon as we have a clear path it will be posted.
  • Niv KA - Tuesday, December 6, 2005 - link

    That would mean I could buy a 975X based MB with a Celeron and buy a Conroe in the summer without having to buy a new motherbord and all

    When the graphs shows both min framerate and max framerate, I suggest that ordering should be done by the min framerate instead of the max framerate. Only on F.E.A.R. Performance test on the 9th page the results will change, and only for the top two boards - however, I prefer to have good consistent high framerate in the worst cases than extremely high framerate in the best conditions.
    Thanks
