Evga 790i raid setup

Thanks to OCZ for providing these units for our use in testing. Vertical refresh sync vsync was disabled for all tests. All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them. And what a memory controller it is. They show access latencies across multiple block and step sizes, painting a fuller picture of memory controller performance with each chipset.

Yellow represents L1 cache, light orange is L2, and dark orange is main memory. Note how much quicker the Ultra is with higher step and block sizes than its rivals.

WorldBench uses scripting to step through a series of tasks in common Windows applications. It then produces an overall score. WorldBench also spits out individual results for its component application tests, allowing us to compare performance in each. Our nForce i and i platforms are using slightly different driver revisions, which would explain the minor discrepancy in IOMeter performance between them.

Otherwise, the nForce chipsets do a good job of keeping up with Intel. The ICH9R boasts slightly higher transaction rates with a couple of load levels, though. Response times are even practically across the board, with the Ultra only falling a little behind under the most demanding load.

We tested with HD Tach 3. A crossover CAT6 cable was used to connect the server to each system. Pay no attention to the higher CPU utilization of the nForce chipsets. We measured system power consumption, sans monitor and speakers, at the wall outlet using a Watts Up Pro power meter. Power consumption has perhaps been the single greatest weakness of nForce chipsets, and with the i SLI Ultra, it appears little has changed. At idle, the Ultra sucks about 15 more watts than a similarly-equipped X48 board.

That margin shrinks to ten watts under load, though. The Asus P5K3 Deluxe motherboard we used for testing has much higher power consumption than other P35 boards. For our overclocking tests, we dropped our CPU multiplier to 6X—its lowest possible value. The memory bus was also maintained at MHz to keep our DIMMs running well within their limits at overclocked front-side bus speeds.

Next, we turned our attention to the front-side bus, cranking it up and using a combined load of Prime95 and the rthdribl HDR lighting demo to test stability along the way. However, getting the system stable with a MHz front-side bus proved a little more problematic.

Then again, your mileage may vary. With a set of EPP 2. DDR3 is really delivering on its potential for higher clock speeds, and the nForce i SLI Ultra is primed for the fastest modules on the market. Firewire and audio are farmed out to auxiliary chips, for example. Intel chipsets also rely on third-party silicon for networking, and many motherboards feature additional SATA controllers to complement south bridge Serial ATA offerings. Our i-based motherboard is highlighted and in bold to make it easier to pick out from the crowd.

An all-new north bridge lies at the heart of this latest nForce chipset, complete with a DDR3 memory controller that not only boasts significantly lower latencies than its rivals, but also supports memory speeds all the way up to MHz. Nvidia built the i SLI reference platform with enthusiasts in mind, endowing its BIOS with arguably the best mix of overclocking, tweaking, and fan speed control options on the market. This all comes neatly packaged on a new motherboard design that sports a solid array of integrated peripherals, including support for multi-channel digital audio output.

The layout of the new board is nearly perfect, and it can even accommodate some of the largest aftermarket processor heatsinks around. The first and most obvious is support for SLI—a feature that Nvidia continues to deny its chipset competitors.

With the new GeForce GX2 ready for effective four-way SLI configurations, the i SLI will be able to play host to what should be the highest performance graphics configuration on the market. Obviously, top-of-the-line chipsets like the Ultra are less concerned with value and more about winning bragging rights in a technical arms race. DDR2 is analog?

News to me. PCI data analog? Also news to me. High speed digital that looks like analog; maybe. Just hard for me to imagine analog signals on a digital computer board, but then…. Have to admit, that first photo with the shiny towering heatsinks on the black motherboard like a vision of a dystopian future city, is awesome. I have bought a lot of motherboards, and this thing costs nearly as much as all of them combined. Maybe, if nVidia had managed to make their i SLI better than the a SLI all around, it would be worth considering for some people.

But I certainly would not give it a good review as it is, despite the seemingly very nice memory controller that still mysteriously lets it lose in some game benchmarks. Also performing flawlessly. Try rebuilding your system from scratch with the correct drivers. Or a remote possibility of a physically-damaged port — static zap? They have caused caused countless premature failures.

Solid caps, while preferable, are overrated IMO. Still, I agree that for the price they should have used solid caps. While this is a gross generalization, the main advantage of finer processes is that manufacturing costs go down since you can squeeze more dice onto a wafer. On the flip side, designing a chip on a finer process always incurs a larger cost than making the same design for an older process tech. The required engineering effort is much greater. This is especially true for analog circuits: analog design automation has not reached the level of sophistication available in logic circuit design tools, so a lot more manual work is required.

Selecting the right process technology for a certain product involves finding the best trade-off between design cost and manufacturing cost. Please help, if you could tell me the exact settings, that would be great. DaMulta My stars went supernova. Joined Aug 3, Messages 16, 2.

There is a difference in running pi at 4. Most of those people that do 4. I haven't even been able to hit 4. Just watch your temps and bump the voltage on it.

And when they do, I will watercool them with a Danger Den setup no doubt. Joined Aug 27, Messages 0. The problem isnt the chip, its the i Mobo, they dont play well with Quads, if you really want a good overclock you need to use an intell based mobo like the x38 or x48 , your never going to get a good overclock wioth Quads on a Nvidia board this is fact. Your chip should be able to do 4. Wile E Power User. Joined Oct 1, Messages 24, 4.

At this point I am looking for someone to tell me what settings to start at the exact settings in the BIOS. At least I can start small to get a stable overclock. If I can at least get that much. With my current configuration, what should my benchmark on 3DMark06 be? The total capacity of the PCI Express 2. It will be backwards compatible with PCIe 1. Cool stuff, yet it's so high-end that at this time you will just not notice a performance difference.

The two latest G92 graphics cards already have 2. Two new features have been added that yours truly is actually pretty thrilled about. Name one situation where you are CPU limited and thought it would be nice to get some sort of optimization enabled, you feeling me already? Exactly, we discussed it recently in our SLI and 3-way SLI articles; in the lower resolutions in combination with multiple GPUs we always stumble into a decrease in framerate opposed to a "single" graphics card.

This greatly helps to fight off data-latency in SLI mode. This is what we call a point-to-point approach that reduces traffic latency in-between the graphics processors utilized. Broadcast The second feature is partly new, I say partly because SLI technology was always already based on transmitting the same data to the multiple GPUs, but in a slightly different fashion. Compare this with a network HUB and a Switch.

In a HUB data-packets are transmitted to all ports, in a switch the data-packets are transmitted to a specific port.

Remember Me? What's New? Page 1 of 2 1 2 Last Jump to page: Results 1 to 25 of So far it is not going as smoothly as I had hoped. One thing that seems to be weird, is that I really haven't done anything to the BIOS so far, other than disable the onboard audio, enable RAID, and change the boot sequence.

Yet for some reason, half the time I boot into Windows, the computer locks up after about 5 minutes. No BSOD, just locks up. What is weird is I have been able to run Orthos on all four cores for about 3 minutes I ended because I felt at stock speeds that was long enough , and also ran 2 MemTest's for MB each for about 7 minutes before I ended them. Any help and assistance with this would be greatly appreciated!

Thanks in advance! Last edited by Natalia; at PM. Windows 10 - x64 Intel i7 k Sandy Bridge-E 4. Are these 1GB sticks or 2GB ones?
