Why so slow? Did I pick the wrong type? (type listed below)

Performance test 7.0 block read/write, "Memory speed per access step size" = average speed 14.69 MB/sec.

One stick in slot 1, one stick in slot 3

Dram frequency 1066mhz
Dram voltage auto
Bank interleaving Auto
CAS 5
tRCD 5
tRP 5
tRAS 15
tRTP auto
tRC auto
tWR auto
tRRD auto
tWTR auto
1t/2t memory timing = 2t

unganged mode

Torture test runs with no errors, windows memory test shows no errors.

Tried various setting changes but no help in speed

examples,

Tried "ganged" mode

Dram voltage manually set to 2.0v

Dram timing mode "auto", sets it to 5-7-7-15 according to cpu-z.

Motherboard- MSI K9N2 SLi Platunum 750a
CPU- AMD Phenom 9500 X4
Memory- G.Skill F2-8500CL5D-4GBPK
Video card- Geforce XFX 9800GTX+
Power supply- Antec True Power 20, 550w
Hard Drive- 2-80gb WD800AAJS Windows 7 RC1 32bit
Hard Drive- 2-500gb WD5000ACS-00G8B1 windows XP pro 32bit
Hard Drive- 1-100gb Maxtor 6100PL windows Vista business 32bit (IDE)
Monitor- Acer H233H.

Tried 32 bit XP pro, Vista, windows 7.

Tried 64 bit XP and windows 7.

All report poor memory performance.

Had to edit to fix it, computer I'm using to post this with decided to suffer keyboard issues/problems mid post here screwing up the whole thing.

auto timing and voltage would not make it run correctly
you'll have to set them manually to DDR2 1066 5-5-5-15@2.0-2.1v
and we notice your CPU is 9500, so is it with TLB bug?
if it could not reach this spec, try to increase NB voltage to 1.5v and please make sure your BIOS is up to date
thanks

I see my post is not really all that clear and has no title for the thread.
Dang keyboard failed typing the thread posting it before I was ready, could not find a way to edit the title after the fact. All kinds of stuff started opening on the screen too making it real fun!

Anyway I have the timings set as,

Dram frequency = 1066mhz
Dram voltage = auto
Bank interleaving = Auto
CAS = 5
tRCD = 5
tRP = 5
tRAS = 15

tRTP = auto
tRC = auto
tWR = auto
tRRD = auto
tWTR = auto
1t/2t memory timing = 2t

Dram voltage = 2.0v

Timings in red are set to "auto" as I do not know what to set them to. I assume I have the first 4 correct right?
I wanted to know if there is any other adjustments I should make and if the benchmark example I posted is in the ball park for the computer as built.
The baselines listed in the program itself list the cpu and amount of memory installed in the systems but not the type and speed they have so it doesn't really tell me much.

I didn't know what to expect but thought it would be higher then Memory speed per access step size (read) = average speed 14.69 MB/sec.

My 4+ year old laptop P4 3.06ghz running 1gb of pc2700 memory gets average speed 20.5mb/sec running the same benchmark.

Just want to make sure its where it should be.

Thanks for any help/suggestions you can offer, Dan

we notice your CPU is 9500, so is it with TLB bug?

"TLB bug" I do not know what that is so I can't answer yet but will try and find out and let you know.

[Danrb]

Ok I just looked it up and from what I read/understand mine would not be effected by that even thought it is a "B2" revision, it is a 2.2ghz model?

While I did read a couple things I may not be real happy about it should work for now, then maybe find a newer faster model.

Anyway thanks for drawing that to my attention, my first "AMD" and kinda jumped in the "deep end" of the pool in the process as I'm quickly finding out.......
