The Venice on the DFI Ultra-D, really tested it's ability... This system typically runs a FX-55 and it's capable of 8X360FSB
Specs DFI nF4 LP Ultra-D ADA3500DAA4BP CBBLE 0512DPAW BIOS: 310P CPU: Maze4 Waterblock Chipset: Stock Cooler Memory: A-Data DDR600 200 1T 2.5-3-3-14 eVga PCX5750 Video Card Western Digital IDE 20Gig ATA100 Tagan 480Watt PSU
The system booted into Memtest86 at 10X300, but hung in test #4... Backed off to 10X295... Note Memtest mis-identifing the Venice...
The unfortunate thing with the A64 systems, is no half multipliers. This forces certain settings which may not be optimum. To back off on the multiplier to 9X would require the FSB to go to 327. The A-Data won't run that high at 2.5-3-3-14, so I'm stuck under 300... But the Venice is a real winner!
Note the poor memory bandwidth and the somewhat poor SuperPI score. I guess the 512K cache makes the difference....
Also note the CPU temp in the lower right hand corner... While I am water cooled, the FX-55 at lower speeds, ran the temp about 10°C higher...

Switched the FX-55 back into the system. While it's not memtest stable until I back down the FSB to 10X285, the bandwidth is 10-15% higher due to the 1Meg cache...
So, while the Venice overclocks higher then the FX-55 in the same system, the speed as measured by the bandwidth and SuperPI, is less then the FX-55....

Wow! That is very suprising on the bandwith issue. Guess it really starts bottlenecking the CPU at high frequencies like that. Although... i wouldnt exactly call DDR600 a bottleneck
Im sure with a little tweaking you can hit that 3G mark with the new core! Still, awesome results!

Polygon, seems you are running the 2x256 TCCD in your tests? I'm curious, how do the LEs you had earlier do with the Venice on this board? Didn't they do 300 at 2.5-3-3-6?
Sorry if I missed anything: I was on vacation for a week.
And yes, going from a Winnie to an FX-55 you gain about 300-400 points in 3DMark2000/2001 due to the 1MB L2. Also 2x256 MB sticks lose a lot of bandwidth to 2x512.
Also, your results suggest the memory controller on the Venice is better than the FX-55???

I have a Venice 3000 coming and will install it in the DFI Ultra-D... Right now I'm running the 3500 Vinnie in the MSI Neo4 Plat and am having a limit of 295 with the 2X512 "LE"s. But that is probably the board....
When I get the 3000, I'll go back to the DFI....
In testing the 5 nF3/nF4 boards with the Vinnie, I've only had to make minor changes to the mem timings to reduce or eliminated errors in Memtest...

Actually the Venice cores are all assorted. The steppings on them really determine which ones require more vcore to overclock. The best ones are the "PAW" chips whether it be DPAW or APAW, if you've got one...you know what I mean. My 3200+ LBBLE 0515APAW does 2.75Ghz Prime stable with stock vcore. 2.8Ghz and higher requires only 1.5v...this is all on air cooling w/ an XP-120. My max overclock is 2.91Ghz but requires 1.53v....not bad eh? I might look into some higher-end watercooling to see if I can reach 3Ghz!
