NFORCE 780a SLI Motherboard Comparison
BIOS and Overclocking
CPU Reference Clock | 200 - 600 MHz (2 MHz) |
Clock Multiplier Adjustment | Yes |
DRAM Ratio | All CPU On-Die Memory Controller Ratios |
PCIe Clock | 100-200 MHz (1 MHz) |
HT Link Multiplier | 1x - 13x CPU Reference Clock |
CPU Vcore | Stock - 1.800 Volts (0.025 Volts) |
MCT Voltage | 1.200 - 1.800 Volts (0.025 Volts) |
HT Link Voltage | 1.200 - 1.575Volts (0.025 Volts) |
PCI-E Voltage | 1.20 - 1.35 Volts (0.05 Volts) |
nForce 780a SLI MCP Voltage | 1.20 - 1.575Volts (0.025 Volts) |
DRAM Voltage | 1.80 - 2.50 Volts (0.10 Volts) |
CAS Latency Range | tCAS: 3-7; tRCD: 3-6; tRP: 3-6; tRAS: 5-18 |
MSI includes the most important overclocking adjustments at wide enough ranges to suite most users, including HT and PCI-Express clock adjustments that go well beyond the capabilities of the components they control. CPU core voltage is also aggressive at up to 1.80 volts maximum, while DRAM range is a little more conservative at 2.50 maximum volts.
MSI’s Cell Menu contains the most frequently used overclock settings, plus a few submenus for advanced controls. Minimal scrolling is required to reveal everything from the TLB bug fix control…
…to spread spectrum settings. Unlike ASRock, MSI differentiates the labeling of the CPU’s memory controller and the motherboard’s “Northbridge”.
Unlike many of MSI’s Intel boards, this Socket AM2+ equipped model has “Automatic” configuration settings for individual timings. This is a great improvement, since moderately experienced builders can easily set common timings such as “CAS Latency” but rarely know the correct value for tRRD.
The K9N2 Diamond provides two registers to store custom settings, making it easy to go back to a previous configuration after resetting BIOS.

a 6pack in so after reading all this.. i think im stickin with my 790FX. i was waiting for a quite a while for nvidia to pull something here with the 780a chipset. In my eyes its a fail.Reply
AMD's 790FX chipset provides significantly more lanes than nvidia. 3-way SLI is a novel idea but at x8 lanes for 3 slots.. not so much. while amd is providing full x16 support.
good info tho. if anything i would recommend the ASRock board also for nvidia's SLI path. -
johnbilicki I wan to see boards with two 16x slots and one 4x slot. Honestly I'm not interested in 100+ FPS at 1024x768 or 1280x1024 which is what you'll get in most games with triple SLI. The MSI board looks like they could have fit a couple more USB ports next to the useless firewire port. It's 2008 and I have yet to even see a product require a firewire port on products I'm only browsing on sales sites like Newegg or even just review sites. I liked Gigabyte's new quad gigabit port motherboard, finally 8 USB ports on the back! Also if no one shows up with a router at your LAN party three of your buddies can merely connect to your system any way (and who doesn't have dual LAN ports these days besides your cheap who cheaps out by five bucks on a north bridge).Reply
What is with the waste of brackets? Give us four USB ports on a bracket. If you upgrade even only once every four or five years you probably still have about five or six brackets laying around somewhere with all the firewire ports you could ever want...and if not your buddies do.
The dual-slot coolers on single slot cards, what a waste! If you're going to use a second slot don't waste the opportunity to move that hot air the heck out of the case!
My last criticism is the i-ram...DDR-1?! I love Gigabyte when it actually bothers to make boards using chipsets I'd want (they skipped the true 16X SLI and jumped on the then useless AM2 bandwagon however). So why aren't we seeing DDR2 RAM-drives? 4x4GB/32GB would be far out of most people's budgets but a 4x2GB/16GB RAM drive at $40/$160 dimm/total would *own* a raptor raid 0 any day in price/performance.
The manufacturers need to seriously start bringing some people in to the design rooms to question WTF they're thinking with their product designs because I see no reason to bother spending any money right now.
...and to clarify I enjoyed the article itself, it's just the products I hold disappointment in. The new chipset is great overall though. -
nukemaster DDR is still faster then any hard drive interface anyway(DDR 266 @ 2128MB/s), so why not? its actually limited by its sata 150 interface not the ram(it would also max sata 300).Reply
I agree DDR2 is the way to go, but only because the price is much lower and better capacities. When gigabyte designed the I-ram ddr was cheaper and ddr2 was new and expensive.
I think there is a DDR2 I-ram in the making -
I own an evga 780i and I am plagued with the video corruption problem like many other nvidia 7 series owners. BEWARE before you invest on these boards. Nvidia hasn't released a fix in 3 months. Many people can't watch video or play games without encountering a hard lock-up.Reply

jabliese No comparison of just the integrated graphics? One of the selling points for the 790 is it's DX10 support, would like to see some kind of comparison between just the integrated graphics, say, maybe on HDTV playback.Reply -
unifiedonboarddecoder They should also do the test using an ATi video card. I would like to see those benchmarks as well.Reply
