    I've heard about a simple solder mod that can overclock a Dell 8400/XPS Gen4 with a 925xe mobo and 6 series P4's.

    Basically you solder bsel0 to bsel1 contacts on the cpu which tricks a 925xe which supports a 1066mhz FSB into thinking you have inserted an EE cpu so it switches from 800mhz FSB to 1066mhz. So your 3ghz 800mhzFSB 630 (200x15multi) becomes a 4ghz 1066mhz EE (266x15multi). This works for definate on stock voltages and stock Dim 8400 cooling to boot. The guys that have done say it is 2 instance prime stable, so I have no worries with the improved cooling of my XPS Gen 4.

    To the point though!

    Unluckily for me, I only heard about this just after I got my XPS. Had I known before I ordered I would have saved a few hundred quid and got a 3ghz 630. Instead I 'splashed out' the extra wonga on a 3.4 650, which unfortunately yields an OC of 4.5ghz with this method (266x17multi). Deffo would need water cooling which would be an added expense, but that is moot anyway as an increase in voltage which would also be required at that level of OC isn't possible unfortunately on the Dell.

    So....

    A. Where can I get the cheapest 3ghz 630. Komplett have them for €228. Is that good?

    and

    B. What would be a reasonable price to sell my current 3.4 650 (without HS/HSF obviously) on the PC For Sale forum?

    1. 4ghz in a dell? I don't know, dells run very very hot

    2. you have to ask yourself, do you really want to go through all that hassle? and risk a computer by soldering stuff? 3.4 is not bad at all and if you wanted a computer that is that fast , why didn't you build one yourself? would have saved you money, time and this problem you are having now

    You lose warranty immediately. I know I'm not one to talk but Dell do have a good warranty. It'd be a pity to pay for a Dell of that standard and then lose the warranty.

    And now for the million dollar question:

    Why in heaven's name did you buy a Dell XPS when you think you have the skills and/or balls to go messing with contact points and solder on a motherboard? Would it not have been better and/or cheaper just to build from scratch?

    Well losing the warranty goes without saying but I've had it a few months now and if anything was going to wrong it probably would have by now.

    As for why I got the XPS, well I was going to build myself this time but then figured I'd have a better chance of getting the VAT back if I put one invoice for a prebuilt system through the business rather than invoices for a load of PC components. That and the discount I got meant I got the XPS, a Dell 24in 2405FPW flat panel widescreen monitor, a 540 dye sublimation photo printer and a 962 AIO printer for the sum of €2200

    Cyberghost, Apparently it is prime stable at stock voltages and cooling in a Dimension 8400 so I shouldn't have any heat problems in an XPS which is twice the size case and has 5 fans as opposed to 2. 8400 has a BTU (heat removal rating) of 400BTU/hour. XPS BTU is 950BTU/hour.

    Was gonna soldier on with my old Dimension 8200 as the second PC but I may actually move that to pure internet duties in another room and pick up a Dimension 9100 specced with a 630 3ghz and do a swap. Was going to get a 2001FP for use on the 8200 anyway as the old CRT that came with it is dying and because its IQ pales in comparison to a good TFT. I guess that way I can swap processors back if I have any warranty issues with either. Sure the old 8200 with 9800XT was going to struggle at 1600x1200 on a 2001FP anyway.

    Decisions, Decisions!
