New comp, quick question

[VeZ]

24 hours later after first putting my computer together, it seems to finally be stable. One quick question though, I right click my properties on my computer (Win XP) and it says

E6750 @ 2.66 Ghz 2.72 GHz. I was wondering why the second processer is over 2.66. Is this nothing to really be worried about?

 

[cprince]

are you overclocking the processor? The 2.66GHz is what the processor supposed to operate. The 2.72GHz is the speed at which the processor currently operates. Both processor cores operate at the same speed. This might explains why you have stability problem.

No. My readings are ocassionally off a little using amd's cool and quiet. Just shows you that nothing is perfect. Power supply readings are a classic example.

 

[VeZ]

No Im not OC'in the processor. It just came like that from stock..but an extra .6 ghz should really make a difference should it

1333/4=333.33*8=2667MHz
2720-2667=53Hz
340*8=2720MHz
No way your OCing, even on accident?

 

[VeZ]

If it was an OC, then it definetly was on accident. But Im pretty sure my CPU is stable anyway. Its been running for around 2 hours without crashes yet. Should I go into the BIOS anyway and change it?

I would at least go into the BIOS and see what it says.

and change the 340 to 355

I doubt that the motherboard maker set the FSB to 340 stock, something else is going on here.

Have you run CPU-Z to confirm this reading?

By the way, it's 0.06GHz faster, not 0.6GHz. And I doubt that a tiny OC like that would cause instability.

Sorry bout my math error there Denithor

OK here is a screenshot from CPU-Z...

Says my core speed is only 2.04ghz with only 6x multiplier instead of 8...whats going on here

EDIT: I just saw the multiplier jump to 8 and the reading go to 2.666 like it should. Then it dropped back down to 6. I read somewhere that it idles at 6x mulitplier and goes to 8 when it is needed. Is there any way just to run it at 8 all the time? Wouldnt it stress the CPU if it switched from 6 to 8 all the time?

NVM Guys, I did a bit of research and found out its a default power saving mechanic and I can disable it in BIOS if I want. I dont have any games installed yet as this is a clean computer to see if the multiplier will actually jump to 8x when needed, but if it doesnt then I will just disable the power saving stuff in BIOS

 

[DSF]

The power savings stuff should work fine, and it doesn't stress the CPU at all.

 

[Tempered81]

its called speedstep and you had your fsb at 340mhz, you can disable speedstep via bios to make it run on your 8x mutli fulltime. many overclockers run 3.5ghz range with speedstep disabled. I dont think this is good for the long term life of the chip, so i keep mine enabled.

 

[VeZ]

Well I just played UT3 for around 2 and a half hours straight on the rig and it was flawless. My 8800gt only got up to 60c with the stock fan too!

 

[Denithor]

Speedstep (C1E and EIST in BIOS) only kicks in when your cpu is idle, drops the multiplier to 6x and the voltage slightly to reduce speed/temperature and therefore prolong cpu life.

And based on what you saw, CPU-Z is showing your chip operating at the correct speed now.
