I thought I would share a personal review about the XFX 750i SLI nForce mobo just in case somebody out there is thinking about buying this mobo. I had totally underestimated this mobo :roll: This was the first mobo I had swapped for. I had trash-talked this mobo when compared to the stock XPS 630 mobo. After spending some quality time tinkering with the bios, I had discovered that this passively cooled mobo can provide a 25% to a possible 30% OC on air-cooling when using a Q9000 series cpu. *I currently have a stable Q9400, OC’ed at 3.42GHz (fsb of 1714MHz) with memory running at 1000MHz (FSB/DRAM is 6:7) :) The trick to OC’ing this mobo is to obtain a good understanding of the bios. The mobo uses a much modified bios by American Megatrends. In all honesty, if you’re not the patience-type, do not waste your time buying this $100 mobo. It’s advertised that this mobo can OC to a max FSB of 1800MHz…for dual cores…YES…for quad cores…NO but with the right OC settings, that quad core can slightly go beyond 1700MHz ;)

Here are the highlights of this mobo:
1. Depending on CPU, max FSB OC’ing for quad cores is slightly over 1700MHz while for dual cores is 1800MHz
2. Dual SLI, pci-e lanes are configured at 2.0 16x+8x respectively (24 lanes available)
3. All solid-state capacitors on mobo
4. LED indicator and clear CMOS button on rear I/O panel
5. Good recovery from failed OC.

Here are the major frustrations with this mobo:
1. This mobo does not OC memory that is 1066MHz or higher. When OC’ing 800MHz memory, do not expect to go any higher than 920MHz. If you want the memory to operate at 1000MHz or slightly higher, you must use 1066MHz memory. If you want to the memory to operate at 1100MHz or slightly higher, you must use 1200MHz memory. So technically you will have to settle for a memory speed slower than the stock memory speed when using 1066MHz or 1200MHz. Now, honestly this is not a bad thing when OC’ing your CPU because the memory speed will adjust itself to the recommended speed in relation to the OC’ed CPU.
2. There is no OC memory setting in the bios for sync mode or 1:1. It is automatically set and locked for a link OC setting. So whenever you change the CPU OC, the memory speed will automatically adjust itself. You can manually enter a speed but you must be aware of the FSB/DRAM ratio you are creating. Not understanding this can effect the overall performance of the cpu/memory OC or the OC will definitely fail when stress testing resulting in a BSOD.
3. The voltages are very limited for the vcore and vtt fsb.
4. Not enough voltage increments for the vcore, vtt fsb, north bridge and south bridge.
5. Not OC friendly.

Things to be aware of when OC’ing with this mobo:
1. Voltages can only be change for the vcore, vtt fsb, memory, north bridge and south bridge.
2. There in no CPU Thermal Control, C1 Enhance Halt State and Virtualization Technology to disable. You can only disable the Executable Disable Bit, Spread Spectrum, HT Technology and Intel Speedstep (Intel EIST Function).
3. If OC’ing the cpu using 800MHz memory, 1:1 ratio is preferred but do not disregard a 5:6 ratio using tighter memory timings.
4. If OC’ing the cpu using 1066MHz memory or higher, 5:6 or 6:7 ratio is preferred with tight memory timings for better performance. You will have to calculate the FSB:DRAM ratio and manually set the cpu FSB/memory speed to reflect this. This also applies to using 800MHz memory.
5. Regardless what memory speed used, tighter memory timings are highly recommended for best cpu/memory performance.

Heatsink limitation when using this mobo inside the XPS 630i chassis:
If XFX 750i SLI nForce mobo is installed in the XPS 630i case, the largest heatsink that can be installed is the Xigmatek Baldur or Dark Knight or any other heatsink that is similar in size.

The afterthoughts:
The mobo provides dual SLI in 16x+8x respectively, provides mainstream OC’ing results (depending on the cpu being used), recovers from failed OC’s well, and provides good stability if running at stock cpu/memory speed.

The question is :think: Can you overlook the frustrations of this mobo :?: YES :!: if you're
1. comfortable about achieving only 25 to 30% OC’s,
2. have patience to understanding the bios,
3. do not mind calculating the FSB/DRAM ratio
4. endure the numerous stress tests…

I will stress this…if you do not fit into the (4) “must haves”, do not waste your time in buying the XFX 750i SLI nForce mobo.
For $100, I think this is an awesome buy for stock cpu/memory speed. I also think it’s a great buy for mainstream OC’ing…if you have the patience ;) :mrgreen:

If anybody owns the XFX 750i SLI nForce mobo and need some help OC'ing, PLEASE POST YOUR QUESTIONS HERE. It's not as difficult as it appears. The OC settings within the bios is on the thin side :think: you have to do more trial & error than usual :think: and have a bit more patience with the mobo :thumbup:

Thanks :mrgreen: and YES...it's a nice mobo once you get the hang of it's capabilities but the learning experience was not enjoyable :crazy: :lol:

Remember :!: Post all OC questions in this thread...Nvidia 750i, 780i, & 790i Overclock Assistance :mrgreen:
