<title>Win7 64bit now won&#x27;t let me use &#x22;8 cpus&#x22;.</title>
<link>http://www.dslreports.com/forum/remark,23363800</link>
<description><![CDATA[So I have the corei7 920.
Intially when I installed win7 64 Pro I installed with HT flag turned on in BIOS.  So it results in 4 cores and 4 Threads for the total of "8 CPU's".  The windows reflected that correctly and so did CoreTemp.

I initally hit the was in Overclocking at about 4250 at 1.35V (didn't want to go higher in voltage).  Then I read that if you turn off HT, the CPU will drop about 10C in temperature and it will allow for higher clocks.  Ergo, I go to bios turn off HT and up the Baseclock.  Now I can run at 4380 Stable and Win7 correctly reflects 4 CPU's (4 Cores no Virtual Cores (HT)).
So yesterday I go back to BIOS and decide to turn HT back on.  Now the system boots (at lower MHZ 4250..had to change it back) but it shows only 4 CPU's in windows...CoreTemp reflects that and it states 2 Cores 4 Threads (so 4 CPUS two being real and two vertical).

So I go back to bios and turn the HT flag off, go back to windows still 4 CPUS now 4 Cores and 4 Threads.

So what gives?  Is it windows or the hardware?]]></description>

<title>Trying to understand FSB:DRAM in CPU-Z</title>
<link>http://www.dslreports.com/forum/remark,23352014</link>
<description><![CDATA[I could not find any reference to my particular set up in googling so I hoping I can get some information here. 

I have a ASUS M2A-VM HDMI with a Phenom 9600 BE.   2gig ram DDr2-800.
Now CPU-Z says 
11.5 X
Bus Speed 200
HT link 1000
NB Freq 1800
I do have PC2-6400 RAM but I have it running at DDr2 400
to get a FSB:DRAM  of 1:1
If try to run ram at 800  I get a ratio of 1:2

In that latter could I end up with a bottlenecks in the CPU?  
What are symptoms of bottleneck in the CPU?  

I trying to understand how this works. Do you always want to see a 1:1 ratio?
Thanks. ]]></description>

<title>Is 80C too high for 920 D0?</title>
<link>http://www.dslreports.com/forum/remark,23262214</link>
<description><![CDATA[I have 920 D0 OC to 4.2 Ghz at 1.35 Volts running water.
With Prime95 blend I get 78C with 27C ambient
and with 
Prime95 small FFT (all fits in cache so just CPU tested) I get about 81C with ~27C ambient.

All after 30 min of Primeing.

Are those temps too high for that chip and setup or is it standard?]]></description>

<title>CPU-z (so which is it?)</title>
<link>http://www.dslreports.com/forum/remark,23309242</link>
<description><![CDATA[I always thought CPUz was a good program, no?

I have E8400 with Asus P5Q Pro. I think the default is 9x333 so I set the FSB to 400 in the BIOS (nowhere to change the multi). RAM went to 801 from 800MHz.

Core voltage doesn't seem right either. I didn't change that, nor should it have changed from 1.1 something.

Ideas?]]></description>
