E6750 not running on GA-P965-DS3 well??

[fire_storm]

Hi

i recently got a new E6750 instead of my old P4 but it seems that it isnt running as fast as it should can anyone tell me how i can test it to make sure it is functioning well..

my setup is

E6750 (no OC)
2gb corsair 800
7600 GS
4x250 Gb HD (no RAID)
1x80 gb HD
P965-DS3 rev 3.3 F12
Windows XP pro

Superpi. Run 1M and you should get 19s on stock.

Wow, thats nice and fast, I get 37s overclocked :lol:

If you've had the board for a while you should flash the bios and confirm that your FSB is running @ 1333.

What processor do you have?

 

[nukemaster]

Well first of the 965 chipset was made for FSB 1066 and not 1333.....

But according to gigabyte with f12 it should work....

Please define slow?
Have you run cpu-z to make sure its running at the right speed?

 

[randomizer]

What processor do you have?

3700 @2.6

 

[nukchebi0]

That makes sense, then. You only have one core.

 

[MrCommunistGen]

Make sure your computer is recognized as an ACPI Multiprocessor system instead of single processor. I've never transitioned from single to dual core on the same OS install so I'm not sure if it'll do it on its own.

i got 3100 on 3d mark as a total score ...
the CPUZ does show me my CPU but it shows the core speed as 2000 , it should be 2600, it used to be shown right but when i pluged in an extra HD this happened.
it could be the OS..
are there any good CPU benchmark programs to show me if mine is ok?

 

[nukemaster]

2000 is right in line if speed step is on....when is shows this is the multiplier 6? if so...puts some load and see if it goes to 8(2600)

 

[nukchebi0]

Run Superpi as I told you earlier (on 1M). It is the easiest way of gaging CPU performance.

I just ran it on Q6600 @3G and got 17 sec. It appeared to use 2 cores and a little on a third. Weak.

 

[nukemaster]

Superpi seems to be single threaded. check the task manager only 25% total. so one core @ 3 would run as good....

Either way 19 should be about right for the other system then

 

[nukchebi0]

Oh, I didn't know. It only made sense considering it was written for a computer with multiple processors.

 

[Zorg]

The original Task Manager readings were not a true picture. It looks like Super PI is designed for multiple cores, so why the crappy score? I want 5-6 second scores. I guess I'm SOL. Here are some screen shots.

i got 16.5s for my e6550@3.15GHz and it seemed like it used only one core in the taskmanager

edit and whopping 51s for my old A64 3000+ (754 Newcastle)

 

[RetiredChief]

18 Sec f/ E6400 @ 3.2 GHz

 

[nukemaster]

16 here

 

[Scarchunk]

19 on a 6420 @ 2.66. Pretty much the same as the 6750.

 

[nukchebi0]

It uses both cores in task manager for me when I run it. I get 17s with the e6750 at 2.96

 

[nukemaster]

it uses both cores....but does it not average 50% on a dual core and 25% on a quad core?

Thats a single core app and windows is just spreading the work....it is in fact the same speed it would run on 1 core(slightly less in some cases)....

Dont trust me?

Run it with affinity for just one core and see the results....

 

[Zorg]

I set affinity to CPU 0. It loaded the core to 100%, unlike the graph above, but I got the same score 17 sec.

 

[nukchebi0]

Oh, I see.

 

[nukemaster]

that was the point. its designed for one cpu....the spread you get is windows trying to balance it....

Where is the OP.....any results?
