Low Physics Score in 3DMark for i5-2500K

Hi all, I just completed setting up my new build and are rather satisfied with the results. However, my 3DMark 11 Physics Score seems low compared to other's (20FPS when I should probably be getting 30FPS+).

I tried disabling C1-C5 states and EIST and nothing changed (my CPU still runs at 1.6GHz when under low load, but it does go up to 3.3-3.4GHz when under load like during the Physics test). I also tried to run SiSoft Sandra and my Dhrystone a Whetstone scores seems a bit low (73.7/44.4 vs 83.6/48.6 gotten from guru3d and neoseeker). There must be something not right in my config.

CPU: Intel i5-2500K (3.3GHz stock speed for now)
HSF: Xigmatek HDT-S1283
MB: Gigabyte GA-Z68X-UD3H-B3
MON: Samsung 226BW 22in. 1680x1050
GPU: Gigabyte GeForce GTX 560 (900/2000)
RAM: G.Skill 2x4GB DDR3-1600 CAS9
PSU: Corair 850TX (850W)
HDD1: OCZ Vertex 3 120GB
HDD2: Seagate 7200.11 500GB ST3500320AS
HDD3: Samsung Spinpoint F4 2TB HD204UI

Thanks for any info/clues you could provide.

I don't like to bump, but anyone has a suggestion?

Can Windows power saving profile impact that (even in I disable C-states and EIST in BIOS)?

Even some other of my tests seems a bit low. PassMark gives me a CPU score of 6600-6800, but some people seems to be getting upward to 8500-9000 without OC. Anyone with an i5-2500k could run it and tell me their score?

Oh, I also tried to set power settings to "Max performance" in Windows and it changed nothing; tried to disable every power/heat settings I could find in the BIOS and SpeedStep (EIST) still seems to be enabled (I don't think it should make such a performance difference, but I don't know for sure).

I also reseted setting in the CMOS from BIOS defaults, but hadn't time to set the back to "performance" settings yet to see if it makes any difference.

Let me know if you think of something or if you think my score are perfectly normal.

(I probably could make even more tests, but I try to enjoy my new build as well :p )

I dunno 0.o get a lower frequency or a lower latency RAM?
sandy bridges doesn't support 1600MHz or above I think ( you can still use it )

for your entertainment, a creeper face :cry:

I usually get about 5000 physics score in 3DMark11 at stock speed. I once had proper scores for the CPU in Vantage twice in a row (~17000). After reboot I was back to ~15000, but it can be ~14000 as well.

Hi, I have similar hardware configuration (same CPU, GPU and Kingtone 2x8GB 1600 Mhz) and I also get low physics score ( 6400 for expected 6800), maybe it's normal for this configuration or maybe someone found the solution?
