To make a simple cable mod while ditching the middle man MCB which is a passive electrical pass through, simple use two jumper wires to match Pwr sw +/- between Dell cable DM755 (9 pin female connector from Pwr button to mcb) and Dell cable TY407 (10 pin female connector from mcb to motherboard).

I am trying to get the seller to ship it to me (he said he would). it would cost me around $350 total. shipping is around 120 at least from TX to NY. It looks nice outside but inside cable is a mess. I do not know how dusty it is inside, but I guess it would not be great.

Check your BIOS...

​

Is XMP "enabled"?

​

Have you ran CPU-z to see what the clocks actually defaulted to?

Granted I am (was) running BIOS 1.0.5 and have been since it's release...I vaguely remember flashing to 1.0.5 many years ago..3x4GB for a long time, then before I decided to swap all my guts out, I thought I would give 3x8GB a try and it went fine, so I am still running this board and Windows 10 runs fine.

​

I would guess, you will be fine with another 4gb stick...Personally, I prefer to run all matching sticks, and when I was heavy into modding PC's (early '04-'05) I wanted serial #'s sequential :P

​

Anyway, I believe these run at best performance with 3 sticks being they are "Triple Channel" architecture.

>When operating in triple-channel mode, memory latency is reduced due to interleaving, meaning that each module is accessed sequentially for smaller bits of data rather than completely filling up one module before accessing the next one. Data is spread amongst the modules in an alternating pattern, potentially tripling available memory bandwidth for the same amount of data, as opposed to storing it all on one module.

>The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots. When two memory modules are installed, the architecture will operate in dual-channel architecture mode.

LMK, these 3x4GB had your name on them!

the stock motherboard does not have native usb3.0 header to accommodate the 3.0 connector of the reader. Newer Dell XPS motherboard (e.g., XPS 8700) has it. Typically a 19 pin blue header bigger than 9 pin usb 2.0. You could use a 19 to 9 pin adapter to connect it internally to the MIO of 730X.

I have a Black one with X-window and original MIO board & PSU. Would be willing to trade for https://smile.amazon.com/PC-O11-Dynamic-Razer-Tempered-Computer/dp/B07P96XQNJ/ref=sr_1_1?keywords=nzxt+razer+case&qid=1569117838&s=gateway&sr=8-1

Plus whatever it'd cost to rent a crane & a train to where you live.

This is my understanding now. The native stock XPS 730X 1.0.5b would support 3 x 4 GB up to DDR3-1333 (PC3-10600). So DDR-1066 (PC4-8500) would be okay too; but not DDR-1600 (PCS-12800) or higher.

It is possible that A11b is better in supporting 3 x 4 GB DDR-1600. But probably not for DDR-1866 (PC3-14900) and DDR-2133 (PC3-17000). This also depends on the CPU apparently. I am assuming most user have the entry level i7-920.

anecdote: I found this report in Dell community back in 2011: "I have my BIOS on my XPS 730x upgraded to v1.0.5, and on the forums (and FAQ) Dell-Chris M mentioned that the 730x now supports 12GB of Ram, and no longer just 6Gb.

I purchased a Corsair Vengeance DDR3 3x4Gb pack (1600 MHz 4096mb 9-9-9-24 @ 1.50V, link = http://www.amazon.ca/Corsair-Vengeance-240-Pin-Memory-CMZ12GX3M3A1600C9/dp/B004CRSM4S/ref=sr_1_5?ie=UTF8&qid=1324934770&sr=8-5), after booting up the PC the fans run, the lights go on, and then there is 4 short beeping sounds, and the fans keep running but slower. This cycle repeats until I force a soft shutdown."
