1.40v was the recommended 24/7 maximum for 45nm Core 2 CPUs, so it stands to reason it would be lower for 32nm CPUs.

Yeah, I really wouldn't worry at all about what hardware monitoring utilities are reporting. If the system completes Memtest86+ passes without error, you're in good shape. Do check and see if Intel has any updates 6-series chipset drivers for download on their website.

Keep in mind that there's a LOT of ways those numbers could have been played with since we don't have any specifics about what was tested. I can pretty much guarantee they used a heavily threaded benchmark like Cinebench or 3Dsmax, and they also probably compared an 8-core Bulldozer CPU to a the 6-core Gulftown i7. If they wanted to be shifty, they could have used exactly 8 threads to max out the Bulldozer but leave the Gulftown with four unused logical CPUs (12 threads total). It's also entirely possible they used an i7 970, while not a huge difference it changes the value and lowers the Intel scores a bit. Sandy Bridge's performance leadership will come from its much higher per-thread performance and the amplifying effects of Turbo boost (which AMD will also support on Bulldozer, but probably not to nearly the same effect).

Dr. Gaius Baltar posted:As an update to the P8P67 Pro and memory, it seems that there's nothing wrong with using your DDR3-1600 memory at DDR3-1600 speeds, as long as the memory isn't defective like mine is. I narrowed down the faulty memory module and removed it, and now my computer is chugging along at DDR3-1605. Why 1605 and not 1600? No idea. I set it to DDR3-1600 in the BIOS, and it spat out DDR3-1605, CL9-9-9-24 1.5v. Probably not a big deal.

Linpack (which is what Intel Burn Test and the OCCT Linpack test use) is definitely the best stress testing program, it finds errors quickly and will easily heat the CPU to 10-15C beyond what Prime95 or other CPU torture tests will do. I like to use the OCCT CPU Torture test for initial testing, and move to Linpack if the CPU handles it for a bit.

If you want to see if you're affected by the bug, try running Crystal Disk Info. I suspect that this would manifest as logged Ultra DMA CRC Errors, so if you're using the SATA300 ports and have those logged, you could be experiencing the issue. Other possible causes for UDMA CRC Errors include bad SATA cables and anything that can cause data corruption, like RAM issues.

There's no point in calling retailers about your boards when the manufacturers just learned about the issue today. Give them a couple days to get things figured out, it's not like fixed versions are even available yet.

Since I'm only going to be using 3 hard drives I can just use the 6.0 ports and be fine correct? Also what's the deal with Marvell ports and are they better than the regular ones?

Anandtech just posted another article with even more details of the defect. Due to a design error, part of the PLL for the SATA300 ports is receiving too much voltage, leading to it burning out. This failure will occur over time, and will be accelerated by increased voltage and/or temperature.

Fitret posted:I've asked about this in the laptop thread, but maybe it's more appropriate here. Short version is that I'm looking at getting a macbook (though I'm not committed, all my current PCs are windows), but I really have a deadline - I'm moving soon (end of Feb) and won't have access to my desktop for about a month, so I think I want to get a laptop before then. Would it be a mistake to get a previous generation laptop? Should I really wait for Sandy Bridge macbooks, or just get a SB windows laptop? I'll probably primarily want to use it for surfing the web / email, WoW, and coding.

brainwrinkle posted:What is the general consensus on load line calibration when overclocking Sandy Bridge? I've heard in a few places that it causes very short voltage spikes on the higher settings and the highest setting can increase the voltage under load. I've got my 2500k stable at 1.35V and medium (Level 3 in the ASRock BIOS) load line calibration. Would it be worth increasing the LLC to drop the Vcore a bit? Do any of the other voltages really matter for a ~4.5 Ghz overclock? FunkyUnderpants posted:Quick question: does anyone know if the Z68 chipset is going to be able to support dual pci express x16 slots instead of crippling them both to x8? I recall that nVidia chipsets a few revisions back could do this on their premium boards, but I've also heard that some suit between nVidia and Intel prevent nVidia from doing the same for us this time around.

brainwrinkle posted:Do you have a source for this? I tried it with LLC turned completely off and I drop about .07v under load. Is that normal? It seems my 2500K is stable at 4.4 Ghz at 1.32v under load, which would mean I would need a 1.39v Vcore with no LLC versus 1.35v with medium LLC. That seems a bit high.

I haven't had the issues with Realtek NICs that others have, but plenty of previous boards have used Marvell Yukon chipsets that worked just fine, is there a reason no one used those on their Sandy Bridge boards? I did some poking around and saw an Asrock board using an Atheros chipset, but that was it for variety. It would be interesting to know what the cost difference is between the Intel and other NICs.

necrobobsledder posted:Looks like the Xeon E3-1220L isn't in stock... anywhere. I can't find the sucker anywhere. It's definitely in the ARK but I guess it hasn't made its way into distribution yet. The 1220L is significantly different from the E3-1220 in TDP and cache, so it's great for home file servers and the like where you care more about power usage than the performance. I don't think any of these Xeons include Romley support since that'll be on LGA1356 and LGA2011 (I seriously wonder if they picked LGA2011 for the year of release instead of for technical reasons). I believe these chips don't include the SAS controllers that the later Xeons will have.

CoreTemp is for AMD CPUs, RealTemp is for Intel CPUs. On popular CPUs they may read the same, but CoreTemp tends to have old/wrong TjMax values for new and less common Intel CPUs, resulting in wrong readings. I'd recommend against using Prime95 because it doesn't stress a CPU very much, I use OCCT because it offers both a regular CPU Torture Test that's similar to Prime95, as well as a Linpack test mode to produce maximum load. Linpack will easily heat a CPU to 10-15C beyond Prime95 or the OCCT Torture Test, and I've had it find errors in just a few minutes on systems that were 24 hours Prime95 stable but having occasional issues. I use the regular torture test for an initial test to see if the system is stable enough for testing and properly cooled, then run Linpack to make sure it's solid and won't overheat no matter what.

The Thermalright Silver Arrow for $74.99 is the best heatsink currently available, and it comes with two of the best fans on the market, the Thermalright TY-140, which push the most air with the lowest noise of any 140mm fan. Here's a review of the Silver Arrow comparing it to the previous king, the Noctua NH-D14. Here's a 140mm fan roundup where the Thermalright TY-140 won. At $75 it's kind of expensive, but if you're looking to overclock as far as you can with low noise levels, nothing will compete, and when you consider the two great 140mm fans are $26 together on their own, its not a bad deal.

Intel has pretty regular price drops, especially in response to AMD products. The main issue is that since AMD hasn't been performance-competitive for a long time, Intel has had no reason to be price-competitive.

That's normal, don't reseat your heatsink. If you were to run a stress test on the CPU you'd probably see the cores settle at a temperature within a couple degrees of eachother. Because the cores are on a single piece of silicon AND covered by a heat spreader, there's no way that poor heatsink contact would cause higher temperatures for some cores over others.

Anandtech just published some additional details about the upcoming Sandy Bridge-E processors and X79 chipset. Disappointingly, only the hex-core processors will be unlocked, the quad-core CPUs are limited to 6 bins above the maximum Turbo frequency, or 4.5Ghz. I'm curious to know what the actual chipset<->CPU bus is, and how many PCIe lanes from the chipset are actually available for devices.

From some quick Googling, when set to Disabled, the core voltage will NOT be reduced at idle, and all power phases will be powering the CPU. When set to Intel SVID, the core voltage WILL be reduced at idle, and all power phases will be powering the CPU. When set to Active Phase Switching, the core voltage will NOT be reduced at idle, but the number of power phases powering the CPU will be reduced according to load. HOWEVER, there have been a number of fixes to power management, so it was possible that the core voltage not being reduced at idle in APS mode was a bug at the time it was tested. To expand on power phases: The CPU is powered by VRMs that convert from 12V to the CPU core voltage. Because nobody makes a VRM that can handle 100W+ AND will fit on a motherboard, they use a bunch of smaller "phases" operating in parallel. The downside is that each phase has some overhead, so if your CPU is sitting idle then you'll be wasting a lot of power (compared to the trickle the CPU is drawing) to keep each phase powered up and converting energy. The idea with APS is that if the power draw is low enough that it can be handled by less than the full number of phases, you shut off the unnecessary ones and concentrate the load on the remainder, eliminating the power overhead of the unneeded phases.
