MSI Neo 4 platinum

I have a ram problem on this board. 2 things.

There are 4 sticks of corsair xms pc 3200 2x256 and 2x512

1. Im running the 180 multip at 230 fsb. for 207 2/3/3/6 (2t) timings. 2.7 volts. In CPUZ only shows 195 fsb. shows 207 during post and in bios.

2. In memory tests on pcmark and sandra I am running only 5gbs when it should be running closer to 6 gbs. This same board/ram on numerous review sites scores the 6gbs.

Ive ran the ram stable at 225 1:1 ratio for the 230 had to do the multi.

My bios version is 1.5. Also I cannot overclock past this amount. Its completley stable at 11 x 230 but wont even posts at 11 x 231. Its a san dieo 3700 chip.

ANY HELP ON ANY OF THESE PROBLEMS WOULD BE APPRECIATED.

Ive ran Memtest works fine, Ran super pi out to 32 m digits heat never got above 47c. Took about a halve hour.
 
using 2x256 sticks + 2x512 sticks= single channel mode, which is likely the problem with your memory benchmarks

also if you are using a Winchester, the memory controller will knock four sticks down to DDR333 and 2T.
 
my bad, that is weird then

try the 1.6official or one of the 1.7xbetas (but you lose 120/140/150/180 dividers)

yeah that is definitely not right, I am getting in the 61xx range on Sandra benchmarks running crappy value ram at 217mhz and worse timings (2.5,3,3,6 1T)


wait a minute...figured out what's going on...

CPU-Z and CPUID can't read the MSI memory dividers properly (both programs think they are DFI dividers)
CPU-Zseems to be applying the DFI 188 divider to the speed you are already running your RAM at 207 on the 180 divider.
I run the MSI 140 divider and RAM speed doesn't even register with CPU-Z or CPUID, shows up as '-1.0' in ClockGen.

Check your Ram speed with Everest, it is the only program that correctly reports my Ramspeed on an even MSI divider.

MSI 180div=0.9
DFI 188div=0.94

Cpuz seems to be taking your actual ramspeed (230x0.9=207mhz) and calculating it with the DFI divider for some reason on top of that (207x0.94=195mhz)

check everest, should show accurate ramspeed
 
It's because you're using the memories in 2T...if you can't use them in 1T, then you won't get the high scores...
 
no, 1T vs. 2T is going to make 1-3% difference in performance tops

not a 20% difference

and that doesn't explain why the ramspeed is being reportedly incorrectly either
 
When I dont use a multi at all it shows up ok. But I cant run my ram at 230 1:1. Do you have the identical board and chip? and if so how high can you get your overclock?
 
yes and no. same exact board, not platinum revision (non-Ultra). NF4 and NF4 ultra are identical for OCing purposes. I have a VNF4Ultra that overclocks basically identically to my MSI.

winnie 3200+, but this board has bugs where ONLY the Winchester and Venice are concerned, SanDiego is unaffected. You shouldn't have any issues with the CPU itself.


I am running 305fsbx8=2440
RAM on 140div ~219mhz, 2.5,3,3,6 1T (2x512 Corsair value)
with better cooling and more voltage, my Winnie goes to ~2.65 and remains stable, 2.7=not stable.

I really don't know what's going on there, but I bet is has to do with running 2x256+2x512

the sticks may not actually be identical, I would take out 2x256 run with just 1GB and see what happens
 
I know there not identical as they were pruchased at different times, however it does say dual channel everywhere, which is what i thought be identical mattered for.

I ask why you went with the lower multi? 8x305?
 
because these three things influence performance, in order:

1. CPU speed
2. FSB speed
3. RAM speed/latency
people get 2 and 3 mixed up too frequently

I can run 244x10, 271x9, or 305x8.
305x8= fastest of the three assuming RAM is running at same speed/timings
gives me an extra 5+ fps in BF2 and close to 150 points in 3DMark05

so when you factor in memory dividers:
244x10=2440 @180 divider=219mhz RAM
271x9=2439 @166 divider=225mhz RAM
305x8=2440@140 divider=219mhz RAM

the extra 34FSB makes a much bigger difference than extra 6mhz RAM
also have value ram, so I can't change timings much (can't loosen and go higher, can't tighten and go lower)
