Hello. Does anyone know that if DDR400 Ram would work in 4000 as DDR400? Thanks.

Is the Ferrari a nice notebook? It sounds expensive.

Here are my sciencemark membench scores for ddr333:
4 cycles / 2ns 4byte
15 cycles / 7.5ns 16
60 cycles / 30ns 64
114 cycles / 57ns 256
119 cycles / 59ns 512

The compiler score is 1046.86MB/s (the other 3 initial tests are in this vicinity), mmx reg 3dnow is 1863.47MB/s (as are the tests up to sse2 palign sse), and the mmx block 4kb and the rest of the tests are around 2075.94MB/s.

moldyn: 96.95574s
primordia (Ag): 469.8662961s
cipher (aes): 14.365621s
blas: sse:5484.2, 3dnow:4705.5, compiled: 1758.2MFLOPS

I'm not going to run the benchmarks again b/c amd's cpu speed tool says the memory is still running at 166MHz. Crapola.


UPDATE
I ran the memory benchmarks after using the tweaking utility mentioned on the next page and it is faster:

4 cycles / 2ns 4byte
14 cycles / 7.5ns 16
55 cycles / 30ns 64
105 cycles / 57ns 256
109 cycles / 59ns 512

(the groups correspond to the general mem scores where I listed a rough value before): 1026, 1100, 1360, 1400; 2228, 2220, 2185, 2253, 2186, 2223; 2505, 2544, 2494, 2546; All are MB/s

moldyn: 97.216s
primordia: 455s
cipher (aes): 13.98s
blas: sse:5680.4, 3dnow:4766.3, compiled: 1794.5MFLOPS

Seems odd since the cpu will support the ddr400, i'm also sure ( might be wrong on this ) the ATI RADEON XPRESS 200P supports it. Maybe the settings weren't auto detected in the bios?

Could you takea peak in the bios?

Unfortunately the bios is as sparse as I have seen. It sees all 2GB, but it has nothing about speeds. I wonder if it will take a bios update to get this working b/c, like you said, the memory should work at 200MHz.

So how many DIMM's do you have, what type, what are the timings, and what BIOS do you have for the F4000?

I took out the original 2 dimms of ddr333 and put in 2x1GB of corsair value select ddr400 (vs1gsds400). I think they are 3-3-3-8, but I am not sure (they definitely have a cas of 3. The bios is s3a17.

Have you tried running with just one DIMM of 1GB?

Does anybody know if this will work on the Ferrari 4005?

I havn't seen the bios of this lappy yet, but the ram may be under the name DRAM clock. Should give a selection for the type of ram ie ddr400 and what not.

i'm probably wrong, but just a wild guess.

I haven't tried with just one stick yet. I won't be able to get to it for a few days at least. As for the bios, like I said earlier, it is spartan. There are no tweaking options what-so-ever. I think the only real hope here is a bios update. Hopefully it will be soon b/c I don't think the apic support is very good given the "broken bios" quote during boot from suse 9.3.

Still no progress on running DDR 400 memory in the Ferrari 4000? I thought even the Ferrari 3200 could do this, but needed to activate it in software or something?

Edit: This is what snorre said about the Ferrari 3200

"1. Run A64 Tweaker to tweak the memory settings.
2. Set MEMCLK Frequency to 200, CAS Latency (Tcl) to 3.0, RAS to CAS Delay (Trcd) to 4, and 2T Timing to Enable (although even more relaxed memory timings will allow for higher CPU overclock with ClockGen).
3. If you've upgraded to Corsair XMS3200 memory you should only set the 2T Timing to Enable."

Anyone care to try? http://www.akiba-pc.com/download.php?view.40

Cool. I changed "refresh rate" from 166MHz 3.9us to 200MHz 3.9us and "memclk frequency" from 166 to 200. When I run the amd cpu utility it says that my memory frequency is reserved. I updated my earlier post on the first page with the new numbers.

Is there any way to do this under linux?

So does it show 200MHZ in CPU-Z?

I'm using amd's cpuinfo, and it doesn't show a speed, it shows "reserved."

Download CPU-Z, it's pretty much the standard for FSB/HTT monitoring:
