anybody can explain this?what is going on?

[sindiy]

I can't set the dram ratio to 2:5,if set can't boot,also,by these settings I can boot to windows but the CPU-Z shows the core speed is only 200x 133 =2.67ghz,I wonder why?

Are you able to change the multiplier instead ?
I'm not on msi board, but somehow i was unable to get it the bclk 200 stable as well on a good temperature and low vcore. But 199.5 seems ok

For 3.6ghz, maybe you can try 180x20 instead ?
The speed thing, you need to disable speed step. When it is running, you will notice the multiplier going up, default is at 12x
Are you on C0 or D0 stepping ? 1.24-1.30 is enough for 3.6 to 4.0 ghz for D0 i think ..

I am running a Xeon X5550 es vesion on my board,till now,I can't find the exactly IOH voltage reading for my board...

It might sound silly but are you using the latest version of CPU-Z? Try downloading other utilities such as RealTemp which shows CPU speed as well.

Plus are you looking at the right section for CPU speed read out? CPU-Z will show the processor type like "i7 920 @ 2.67GHz", but there's another section that shows the actual speed.

Good luck and keep trying.

here is my cpu-Z screen shot,I really can't understand what happened

[Philip]

Errr. You are running on stock speed based on CPU-Z. Why don't you install Realtemp and check out the reported speed.

Set everything back to default and adjust one by one.
Looks kinda messy.
Dun adjust ur PLL voltage yet, leave it @ default/auto.
Increase ur bclk gradually instead of pushing straight to 200.

i like ur IOH temp. my x58 Pro-E just stays at 79C.

keke,I remove the original hestsink of NB & South Bridge replaced by my 2 HR-05,also in aircon room,that's why the tempreture so low.

try these settings. also your QPI Freq is set to 6.4 which is high. the 920's default is only 4.8.

191x21
vCore = +.15
vQPI = +.20
PLL = 1.84
mems = 1.65 (set the timings manually as per your rams)

or try this guide:

Under Cpu Features
C1E: Disabled
Speed Protection: Disabled

====================

Hm....maybe due to the cpu is Xeon Engineering Sample(ES)??

It looks like the mobo does not support yr Xeon...need microcode update, perhaps??
