had to setup a dell XPS i7 system the other day for a client.
all i can say was it the slowest thing next to a turtle.
-
was they upgrading it???
-
nope new out of the box from dell ..
6 gigs with a i7 920 running 64 bit home premium..
-
Correct me if I'm wrong, but isn't i7 one of those dumb setups that underclocks itself horribly until stressed, then it overclocks itself back to "normal"?
IMO that's a bad idea for a system. Unless you're pushing it, it'll be slow as crap? No thanks. I'll take a full-speed CPU any day.

oh, I understand now..........nevermind

Not a good thing.....There was a time that I would consider buying a Dell but that was more than 10 years ago.

Well they did buy a DELL! However their laptops are decent quality and perform well once you eliminate 90% of the junk they ship on them.

All modern CPU's do this to reduce power and heat. You won't see any effect of it since clock speeds raise immediately when needed. It's only a good thing.
What will hurt the system however is a new Vista installation. During the first couple days up to a week Vista will 'optimize' itself and constantly load all kinds of crap to superfetch, do indexing etc. During this time the system will feel really sluggish and out of resources. What's bad is that this process never completely ends and can lag you down occasionally after.
But once it calms down (and if you have dual or more core CPU, single core gets totally choaked by Vista) the most used applications will actually start much faster than in XP and for example AH load times are a fraction of what they would be in XP.

This is a BIOS setting and has been around on a lot of MB since the x38 (intel) and the 690 (nVidia). Is is a simple "disable" in BIOS. But as someone above stated you don't know its happening, the CPU, Mem and Video speed are all throttled.

Heya TheZohan,
not to get off subject here, but did you know you can possibly unlock your dual core and bump it to a quad core?
link & report below, for ya.....

Athlon X2 7750 BE Unlocked to Quad-Core
Earlier this year, a Korean source had pointed out an easy method to enable a fourth core on the Phenom II X3. This was made possible by the way AMD has been designing its triple-core and dual-core processors based on the K10 "Stars" architecture: by disabling one or two cores on the quad-core die. "Sloppy" BIOS coding lead to the Phenom II X3 anomaly. It looks like a somewhat similar mod enables not one, but two cores on the sub-$100 Athlon X2 7750 Black Edition. A Korean technology website GiggleHD.com has reported a successful unlock of two cores.
The method is similar to that of the Phenom II X3 unlock: using flaws in BIOS code to enable cores, by enabling the "Advanced Clock Calibration" feature in the BIOS setup. The OS, Windows XP SP3, was able to see the processor as a "AMD Phenom(tm) FX-7750", while CPU-Z reads the name string correctly and lists the core count as 4. The motherboard in use is an ASRock A790GX/128M.

apologize for the hijack........ but this might make for an extremely cheap purchase for a quad core cpu/system......if anyone was interested.....

That's pretty wild stuff there.

yeah but i dont have ACC in my bios .. i need to get a new mb i was gonna upgrade to a X3 and try and unlock it

you need a 790GX with a SB750 to unlock the cores BTW

Not quite what I meant. Normal CPUs, even at idle, are running at full clock speeds and frequencies, even if not "stressed" -- you run CPUID while idling and it will still say "800MHz FSB, 2.6GHZ" but I read something about the i7 (I think it was i7) sitting idle on the desktop will list as 1.-something GHz and/or possibly underclock the FSB as well.
That's what I was asking about.

Krusty, 'normal' cpu's haven't been running at 100% for the past 5 years if you enabled the power and heat saving functions. Why should your CPU run at full burn when it's not at use?
Amd has 'Cool&Quiet' which also helps lowering cooling fan speeds and Intel has speedstep and other methods for doing the same. They give no performance hit.

Agreed... not sure of the time limit, but all the MB makers have gone green so to speak, all processors are throttled down unless you disable it in the bios. An easy way to see this is using CPU-Z, it will show the processor throttling down (E8400) from 3.0 to 2.4GHz, each board manufacture has their own idea of throttle down. ASUS, EVGA, Gigabyte all have the options easily accessible in the BIOS
