Re: XPS 700 Processor Upgrade

Yes, this was definitely with the basic old 'stock' 700 motherboard.

I upgraded my GPU from a 7950GX2 to a Geforce 260 a week prior to the processor upgrade, and I saw a reasonable amount of improvement in performance with this, but I was staggered how much better the system ran once I put the Q6700 in - well worth the asking price.

Thanks for replying Jim and this is great news. 

I no longer have to consider trying to find a old 720 motherboard / hens tooth.  Tom dropped that honkin 3Ghz QX6800 in a 700 as well - wish I would have known that before, I might have tried for that chip...but such is life.  I've got Q6700 on the way.  My machine, bought it used not long ago, is a 1.9Ghz Core 2 (slowest version), so the performance jump should be "noticable".  😉

Thanks again to you and Tom for putting your experience here.

Re: XPS 700 Processor Upgrade

Jim,

I can't thank you enough for this advice. I've spent MONTHS trying to hunt down second hand XPS 720 mobos with no luck and refused to pay the $289 for a 720 mobo from Dell (which I was told is part # GR909 from their support) + another $200+ for a CPU.

I sucessfully upgraded my 700 mobo with the 1.4.1 firmware to a Q6600 last night. Worked flawlessly and my 3dmark06 score jumped nearly 4500 points! The 1.86ghz E6300 I had was a huge bottleneck for my upgraded Radeon 4870.

Thank you for being the ONLY person on the internet to have this advice. I wish more people knew about this, the motherboard upgrade would be a non issue!

Re: XPS 700 Processor Upgrade

No problem guys, just glad to be of some help.:emotion-1:

In all fairness though, there was a fair bit of activity around the same subject on the old forum, but that seems to have been lost or at least is very hard to locate now since the move to the new format.  Several folks had been successful with the same upgrade, so it pursuaded me to take the plunge myself, so I'm just passing it on really.:emotion-11:

Re: XPS 700 Processor Upgrade

I just got a QX6800 as well and was jsut curious if the current xps 700 fan/heatsink is sufficent enough to keep this chip cooled, or will I need to upgrade it?

Re: XPS 700 Processor Upgrade

Hi Guys,

I do have a XPS 700 with a QX6800 overclocked to 3.46 (from the Bios obtion) running with the stock XPS heatsink and fans and it is running fine,  idle (28 - 30C)  and full load (40 - 43 C) . same as for the memory I'm using Corsair  XMS2 DHX PC-6400 and it's working great even with the EPP enabled in the Bios and @ 2.2 v. Just make sure to use a good thermal paste. Hope this helps.

XPS700 (ORIGINAL MOBO)

QX6800 @3.46 MHZ O/C FROM BIOS

8G CORSAIR PC-6400 @ 801 MHZ

Re: XPS 700 Processor Upgrade

Hi Jim I would really apriciate if you could advise me over this matter. I have a XPS 700 in the original comdition,  except I have 4Gigabyte Memory and an nvidia 280GTX Video card. The processor that I have is 1.86Ghz and I am thinking to buy the Intel E7600 3.06 Ghz Processor. Will this work? I would really appriciate any input and help ASAP. Thankyou.

Re: XPS 700 Processor Upgrade

If my memory serves me correctly that motherboard has the nvidia intel/ 5xx sli chipset.
 
While different, nvidia Nforce based motherboards share the same front side bus chipset with the Dell hybrid intel/nvidia motherboards.
SO- I went to Nvidia and found the motherboard / processor matrix for the different NForce motherboard chipsets.  I attached the list.
 
It came down to this  If the procesor has a 1066 front side bus, it was compatible with the board.
If it had 1333 front side bus - it would not work.
 
This actually has to do with the manufacture of the processor.  I  understand it the 1066 mhz processors are built  made with 65 nm technology.
 
 
The E7600 is made with 45 nm technology
 
 
SOOOO although you are at 1066, the E7600 may still be a problem.
 
 
I successfully ran a QX6600 on a XPS 700 board with the most recent Dell bios for the motherboard.  that would be 5/31/2007  Version 1.4.1
 
I sold my 700 and now own a 720.
 
Hope this helps.
 
PS.  I have tested quite a few video cards lately and I can tell you this  -- The amount of level 2 cache is more important than the speed of the video card.  I
 
 have taken TOP video cards and put them on test motherboards. TOP of the line EVGA triple SLI 780 Nforce boards and with a mediocre processor they run marginally.  I am not a gamer, but on the test bench with a  Pentium D 3.2 800fsb 4mm cache  Geforce 8800GTX , Geforce 9800 GTX and Radeon 2GB  4850 X2 give 3D Mark scores around 7000. 
 
Put them in the Dell with a Q6600  2.4 with quad cores and 8mb cache and they jump up to over 12000.-14000 range
 
Previously tested them on a lesser motherboard with a Pentium D  2.8 800FSB 2 MB cache and got scores in the 4500-5000 range.
 
 
SOO draw your own conclusions.  even though I have  more than capable video cards the processors and the amount of cache proved to be the major factor in determining the performance.
All the boards had 4GB of memory

Re: XPS 700 Processor Upgrade

Let me Thank you so much for the prompt reply and taking time for me in helping with this matter. My friend ordered the E7600 via newegg.com. We got the processor in the morning and you were right it does not work at all Now I have no idea how to return the processor since the return policy is very different. Now you mentioned Q6600 will work, I looked for that but could not find any but I found a Q6700 for 200.00$ you think that will work? I would appriciate your help again thank you so much.
