Intel E6850 3.0GHz But Running At 2.4GHz!?? 1

[gmattey]

I have a Intel E6850, it's meant to be 3.0GHz but its running at 2.4GHz!??

In system properties it says, "intel e6850 3.0ghz 2.4ghz"

and in cpu-z it's listed as 3.0ghz but the core speed is on 2400 when should be 3000.

is this normal?

i'm sure someone will probably say update the bios but it recognises the cpu and speeds.

i've attached a link to the picture from cpu-z for you all to look at.

thanks!

yeah thats what i did with the HSF, it's pretty obvious...but now i've got the zalman there's no need for the intel HSF. we could all go on all day about the intel HSF but the the main point is i've got a very good zalman which i'm happy with

Based on the much smaller 65nm die manufacturing process, the dual core E6850 consumes only 65watts and is a relatively cool processor when compared to older single core 90nm die P4's.
The P4 550/560 of 4 years ago touched 115watts and had a fearsome reputation of being almost impossible to keep under the throttling back threshold (the point at which the CPU underclocks itself to prevent damage) the Intel fan, as a result, would inevitably be spinning constantly flat out.
In comparison the newer 65nm process Core2 Duo's are pussycats and simply don't need massive coolers at default speeds.

http://en.wikipedia.org/wiki/Pentium_4

The retail Intel coolers are well designed and can easily cope with whichever CPU they are paired with (not all Intel coolers are the same anyway, top models have copper cores)
Aftermarket high end coolers are really only necessary if you intend to overclock or you happen to reside in a particularly hot climate and of course, they serve the ego in providing bragging rights to the perspex window brigade.

There was a concious move away from the ever spiraling gigahertz race of 3 years ago, towards more sophisticated CPU core design, based on smaller die size with lower power consumption.
As a result ALL new CPU's, AMD and Intel, run cooler than there recent relatives, cooling in genral, is not the massive issue that it used to be.
There is obviously still a need for good airflow but I can remember the days of the Thermaltake V1000A Xaser III case, that had 7X 80mm fans as standard.
Two 120mm fans front and rear are fine and move sufficient air to prevent internal heat build up.

and it definately isnt installed incorrectly, it's just 4 lever things you push down to clip into them mobo, it isn't rocket science, i've got two of the Intel HSF and both of not done their job properly, they let cpu temp go ridiculously high so not faulty products.

I haven't built an Intel system in a few years so I can't speak for the specific attachment methods. What I can say though is that on AMD CPUs it was possible to put the HSF on backwards (i.e., rotated 180 degrees the wrong direction) if you weren't paying close attention. If you did that then your CPU would not be cooled properly.

There's also the matter of the thermal pad. Most people are told (or hear from visiting web forums) that they need to put thermal compound/heatsink compound/Arctic Silver or something similar on their CPU to improve heat conduction to the HSF. What they never seem to get told is that the HSF that comes with the CPU usually has a grey "thermal pad" attached to the bottom of it. This pad serves the same purpose as the heatsink compound, and negates the need for additional compound. In fact, if you put additional compound on the CPU before attaching the HSF you will actually INSULATE the CPU (trapping heat inside it), impeding thermal conduction to the HSF instead of aiding it.

Afternoon kmcferrin
You are refering to older socket 478 heatsinks that came with an aluminium foil coated transfer pad, they are gone now.
The latest retail socket 775 fans just have several bands of paste pre-applied.
As for the 4 retaining pins, they have to be "re-set" each time they are uninstalled/re-installed otherwise there is a possibility that they will not full lock into place and cause insecure/uneven contact which will give poor heat transfer.
All of these heatsinks have to have their base thoroughly cleaned and quality paste re-applied, each time they are installed.

Thanks Martin, that's good to know. The last time I built a system was about three months ago (X2 6000+) AMD was still using the thermal pads.

I just had to chip in to point out that the high temperatures gmattey was seeing could have been bogus. I have an Asus P5B motherboard and its CPU temp sensor reports incorrectly high temperatures to apps like Asus PCProbe. If you use the Intel Thermal Analysis Tool (aka TAT), which reads the temp directly from the CPU rather than the mobo's CPU temp sensor, you can see that the actual temperatures are actually fine.

It's all academic now though!

gmattey,
In a series of stress tests performed by THG (Tom's Hardware) on the first generation of the Core 2 Duo (Conroe), here's what they found:

http://www.tomshardware.com/2006/07/14/core2_duo_knocks_out_athlon_64/page8.html

The Core 2 Extreme [X6800] does not exceed 45°C CPU temperature using the Intel retail cooler in an office environment.

Now if your idle temp was ever higher than 45°C, then there was something wrong with the installation, the HSF was damaged, or you had the system overclocked.

Also realize that taking the side panel off of your PC case usually makes things worse by rendering your intake and exhaust fans useless. You don't "let more air in" as you stated before, but instead remove the vacuum that allows each fan to move air quickly through a small space. It would be like widening your vacuum hose with the end result being less suction...


But as long as you've got what you were looking for, let's not be concerned with why or how!!
