Speed problem with Intel Q6600 (Quad Core) and Ultimate 64-Bit

[Guest]

I've been playing around with both the 32 and 64 Bit versions of Vista
Ultimate on my new PC. The system specs are as follows;

CPU: Intel Q6600 (Quad Core 2.4)
MB: Intel DG965WH
RAM: 4Gb (1Gb Transcend PC 800MHz x 4)
Video: PNY 8800GTS

In Vista 32-Bit, System runs well (Good CPU Utilization) but will not see
all 4Gb RAM (3.2+GB Seen), system seems to be using a fair amount of RAM.
Windows Experience score Rates the CPU at 5.9

In Vista 64-Bit Systetm runs significantly slower than the 32-Bit version.
CPU Utilization near 50% with system at idle for all four cores. Running
simple software pegs all four cores at 100%. System sees all four Gb and RAM
utilization is better than in the 32-Bit. Windows Experience Score has
dropped the CPU to 4.6.

Two other IT people at work with similar system specs have the same problem
in 64-Bit Vista.

Anyone getting good results running 64-Bit Vista on an Intel Quad-core?

FIRST you need to learn to ignore the ram usage in Vista. Is is
different than any OS before it. The more free ram you have means that
Vista is not doing its job correctly. Ram is MUCH faster than
harddrive speeds, therefore Vista is making use of the fast stuff and
leaving the slower drives for XP.
Second 32 bit systems have trouble with more than 3 gig of ram, just
the way it is. Same system, 32 bit versus 64 bit, 32 bit has issues.

Yes, but the 64-bit is so slow, that I can't even use Windows Explorer
effectivly. 32-Bit works like it should.

Also, why would my "Winodws Experience score" drop from 5.9 to 4.6 when
switching from 32 to 64-Bit.

Update to problem.

While searching the internet, I found that this is a common problem with the
Q6600 processor and more than 4gb of RAM. I removed two sticks of RAM and
the speed improved (Even the Windows Experience CPU score was back up to
5.9). I then added two additional 512 Sticks to make a total of 3Gb and fill
all four RAM slots. System is still working like it should.

So, it looks like Vista-64 Ultiimate has problems on computers with the
Q6600 and 4GB of RAM.

I found other forums where people had the same problems with the Q6600, 4GB
RAM and most had the nVidia 8800 GTS/GTX. It was happening with Asus, MSI
and Intel boards. For some, downgrading the Bios a few versions to where the
user had more control over the "memory hole" area for the video card
corrected the problem. I will update the post with more URLs to the other
forums when I get back to work (I placed them in my favorites at the office)

I have the same processor ..same board same amount of ram and 3 ATI 3870s, I
have been running Vista business for well over a year ,,system is screaming
fast and rock solid !! great motherboard and processor combo !!

 

[Drew]

I know that Vista 64 will recognize all that memory and more...Your
motherboard supports 8 gigs of memory so yes you are good there...I would
assume it will work with all those programs as well but to be certain I
would definitely check there respective websites.. Also possible peruse
there forums for any possible bugs that there might be and ways you can get
around any you might have... Sorry I was probably not all the help you
need.. I wish you best of luck .. Enjoy that system as I have greatly
enjoyed mine !!

Hi,

2GB of ram is fine for x64 though the chief reason many use for installing
it is to use more than 4GB. How much you should have depends largely on your
use of the system. Gamers frequently find 4GB to be a sweet spot, and users
of autocad and video editing software can often take advantage of more. Keep
in mind though that memory at addresses above the 4GB mark cannot be used by
32 bit applications, so unless yours are designed to take advantage of x64
there's not much point to installing more than that amount.

That said, wait until after you install x64 to add the additional memory
(and it's a clean install, there is no upgrade path from 32 to 64 bit). The
reason being that there is a timing issue when all 4 ram slots are in use
during an x64 setup (it's not the amount of ram, but rather the number of
installed sticks that is the problem). Once installed, the timing is no
longer a problem.
