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

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.

Well, I don't think it's due to your processor, however I do think it is either the board or vista. I as well have an intel dg965wh board with 4GB of OCZ DDR2 800MHZ RAM. Running in 32bit vista Business Edition, It was perfect, though it only registered 3.2GB of RAM due to it being a 32bit OS. I Loaded in a 64bit version and my CPU usage went off the charts, until I took out 2GB of RAM and since then it's been working perfectly.

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 just built a system with a Q6600. I've got an Asus P5W DH Deluxe
board and 4 GB of RAM. I'm not having any speed issues so far. The CPU
is scoring 5.9 - and the RAM 5.5.

The system is still initializing the Raid volumes that I built with the
ICH7 Southbridge (having a Raid 5 volume and a Raid 1 volume on a
desktop is going to be nice).

The one catch I had when I started out was that the motherboard only
registered 3.2 GB of RAM as available until I went in and changed an
option to allow a 64 bit OS to see the entire RAM amount. That might be
a spot to look for in your BIOS if you're having issues with speed and 4
GB of RAM.

Hello:

Does q6600 work with windows xp 64? Is this processor compatible with it?
I have a q6600, board d975xbx2, 4Gb ram 667, sapphire ati x1550 512 mb.

What os should I use?

Please, help me.

I work with music, graphic design and video.

I still have some questions. Maybe you can help me again.

Does Vista recognize all 4 Gb memory?

Does it work with photoshop cs3, coreldraw x4, finale, adobe audition cs3, macromedia suite, and software like this?

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 !!

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 !!


I have a Q6600, IP35-E, 8800GT-1GB and 6GB of ram, vista runs well on my
config.
pretty sure its a driver/bios problem like what the others have said
earlier, is your installer from MS or a downloaded copy ?

Sorry to bump an old topic.
I am new here.
I have
Intel q6600
4GB RAM ( 2 X 1GB OCZ, 2 X 1GB Crosair) all 4 sticks are 800MHz
Intel 975XBX2 board
XFX NVIDIA 7600GT XXX Edition

I have tried windows vista ultimate. It runs fine when i install it, but starts to slow down with time. And i go back to XP.
Is there a solution to this problem?

Which is hte best ver of windows vista to run on this system?

Hello guyz !

I have ..

core 2 quad Q6600
DG33FBC borad
2 gb ddr 2 ram
160 gb hddsk

i hve installed vista ultimate 32 bit and its working fine, but now i want to install vista 64 bit. can anyone please tell me should i upgrade my ram to 4 gb bcz i have read some problemz above regarding 4gb ram slow downs the vista. and i hve heard for playing gamez on vista it requires to upgrade ram atleast to 4gb. pleaze help !!

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.

I have the Q6600 and didn't even realise it was 64bit!

however now i know i want to upgrade, preferably doing a dual boot so i can keep my 32 bit version "in case".

however i read here that a full and clean install is required.

do you think there would be any issues?

I have a P5N-e SLI motherboard with 4GB RAM and 2x 8600GS

Systemax N2000 Gaming PC - Intel Core2 Quad Q6600-G0 stepping OC'd to 3
ghz / genuine Windows Vista Home Premium X64 / NVIDIA nForce 680iLT SLI
/ 8GB DDR2-800 PC6400 / 250GB SATA / DVDRW / Dual NVIDIA 8600GT 512MB in
SLI mode / Gigabit LAN / 600W / 24 inch SCEPTER monitor (1920 x 1200) as
this allows true dual view (thinking about a second Scepter monitor and
dual BFG GeForce 9800 GT - 512MB GDDR3, PCI Express 2.0, (2) Dual Link
DVI, HDTV, VGA Support in SLI mode. This system runs clean quiet and
very fast.(Crysis has no issues and Portals whiles away the hours) The
only issue at this time is a true 64 bit browser (minefield comes to
mind ) but no x64 bit flash player supported yet....so we muck along in
the mud when we could be flying...All hail the great ADOBE corporation
for the stellar x64 bit support.

Ram is rarely high and cpu's rarely exceed 50% utilization while core
temps average 45C-55C under average loads (I will be going to liquid
cooling soom) Please browse a book called "OVERCLOCKING YOUR CPU TO THE
EXTREME" and find out if you have the Go stepping on you processor (It
makes a difference so you don't overclock your ram if you don't want to
(Tweek each device separately recommended)
Good luck with this issue. There is no issue created by MAN that can't
be corrected ty users working to gether. The only looser is the person
who will not try.


In answer to the origional post Vista x64 with 4+ gb ram is very well
behaived with just a little work.
