Just wear the fucking mask, Bob

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!



Cross-posting from the Linux thread...



Does anyone out there have a Sandy Bridge i7 and want to waste 15-20 minutes doing a kernel build for me? It'd be best if you're running Fedora 14. Just grab the tarball of the 2.6.37 kernel, extract it, do a 'make old config' and then 'time make -j10'

I know since we don't have the same RAM/disks/etc it won't be a scientific comparison, but I'd like to see how much faster the current systems are than my previous-gen i7.

Go for it, curious to see how it performs. I'd like to compare Xen against say, VirtualBox, or VirtualBox on Windows compared to VirtualBox on Linux.

Forgot I didn't have Fedora handy, so I used my Ubuntu 10.10 32-bit VM. VMWare Workstation, gave it one virtual CPU with 4 cores. i7-2600K @ 4.9GHz:
code:
movax@ubuntu-1010vm:~/linux-2.6.37$ uname -r
2.6.35-23-generic

real	16m21.258s
user	401m19.969s
sys	69m14.160s
Didn't have an old .config to feed it unfortunately, so it literally built everything, sorry. Probably not terribly useful info.

Descanting the Insalubrious

For everyone who noticed my overclocking woes earlier, I return my i5-2500k and P8P67Pro and upgraded to an i7-2600k and P8P67 Deluxe instead (since I had the extra cash) and I got the same bus speed errors I was getting earlier. Turns out there was nothing actually wrong with the earlier setup, it was actually CPU-Z. 1.56 doesn't properly measure the BCLK, however 1.56.2 does. "Problem" solved.

Okay, help me out, I've now seen the Z chipset with three different numbers: Z61, Z67, Z68. Which one is it?

Got my Cooler Master Hyper 212+ earlier this week and installed it. Temps are significantly lower (barely breaking 60 at full load with Prime95).

Keeping my vcore at 1.25V, I bumped up the multiplier to 42X and tried to run Prime95 - immediate BSOD. Voltage is back to Auto and honestly with the temps where they're at, I'm not going to worry about it. I'll probably go up to 43-44X and call it good.

I'd recommend OCCT for stress testing, the CPU Torture Test is good for initial testing when you want to see if the CPU is going to quickly overheat or crash, and the Linpack test is great for thorough stability testing (and will heat the CPU up to 10-15C hotter than anything else).

I upgraded myself to the i5-2500K yesterday, and the change in performance (From a wee Pentium E5400, mind) has been amazing. I can capture video from games with near no loss in FPS, can virtualize and emulate like a motherfucker, and everything is extremely responsive.

My old motherboard and processor caused my memory to unfortunately under-preform, and, though I'm using the same memory, that issue has vanished. Surprisingly enough, Windows did not need to be reinstalled after switching to the new motherboard, for which I am pleased. It also allowed me to utilize an older HDD that my old motherboard had disagreed with (It refused to continue booting past BIOS with it connected) The upgrade did break the Hackintosh aspect of the system, but this was expected and I didn't mind greatly.

I was/am a tad irritated with the small stock cooler, but, again, this was expected ahead of time, and when I feel like spending money again, I'll grab an aftermarket cooler before trying any overclocking. All in all, I am very pleased with my purchase, and was able to push my system to right where it needed to be. (An i7 would surely go to waste in my box)

I have a newbish question that may or may not be off topic.

I'm getting a new box with an I5-2400 on an H67 board, along with a GTX 460. I'm interested in running three displays. Is there any chance I'll be able to use the onboard graphics alongside the PCIe card, or will they get disabled? Or is this going to be dependant on the motherboard?

afaik you might be able to do that under win2000 or XP, but starting with vista you can only have 1 display driver loaded at once.

The sensors have poor accuracy at low temperatures. Plus it's normal for each core to be slightly different due to lithographical imperfections.

He has a H67, not a P67. Pretty sure the H67 allows integrated GPU to co-exist with standard PEG cards. As long as both the IGP and PEG are active and connected to monitors, everything is fine.

Well that article is about a workaround for the H67, but I'm not sure about the integrated an ddiscrete at the same time- I thought you couldn't.

edit: Oh I see, I guess you have to have a monitor connected to the integrated to enable it, you can't alternate between both on the same monitor, which is what the workaround I posted enables. Sorry, I guess you can use both as long as you have a multi-monitor setup, but a very important caveat is that you cant drag and drop between displays, which is a pretty big deal if you actually use a multi-monitor setup the way most people do. Sandy Bridge is a loving mess.

Yes, using 2 video cards on 16x slots will do exactly what you describe, that's my setup for my 2x Apple Cinemas and Samsung TV. Works pretty flawlessly.

I don't mean to make a controversial brand-biased post here but you really should be getting AMD videocards if multi-monitor support is important to you, as that's one area where AMD is years ahead of nVidia. AMD videocards (5000-series and higher) support up to 6 monitors per card, and you can combine monitors into a single large display that even works in games, called Eyefinity.

Either Gigabyte boards read voltages wrong or its photoshopped. That's impossible. People need at least 1.4v to get even 5 Ghz.

5 at 1.35 still seems really good.

Looks like Intel made a lil' booboo with the chipset guys. Supposedly the fix is coming out next quarter. The fix of course is a chipset redesign so you'd have to get a new mobo.

What a PITA. This isn't nearly as bad as AMD's gently caress up with the original Phenom but its still bad enough.

The official statement: posted:


As part of ongoing quality assurance, Intel Corporation has discovered a design issue in a recently released support chip, the Intel® 6 Series, code-named Cougar Point, and has implemented a silicon fix. In some cases, the Serial-ATA (SATA) ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives. The chipset is utilized in PCs with Intel’s latest Second Generation Intel Core processors, code-named Sandy Bridge. Intel has stopped shipment of the affected support chip from its factories. Intel has corrected the design issue, and has begun manufacturing a new version of the support chip which will resolve the issue. The Sandy Bridge microprocessor is unaffected and no other products are affected by this issue.

Yep, saw that filter down when I logged into EDN the other day, I was not happy to hear that Why couldn't it have been something other than the SATA controller?

I wonder what symptoms will be; reduction in link speed (host sees SATA 3Gbps only), intermittent errors. Worse case it's silently flipping bits as they travel from point A to point B.

In this case, they reported SATA problems and were making drive manufacturers panic. I'm glad they 'fessed up before other companies wasted more engineering resources trying to figure out Intel's gently caress-up.

Traditional design verification tools wouldn't have caught this (and they aren't expected too either), because it doesn't seem to be a logic error, more of a manufacturing/layout issue. One of the Intel goons might be able to comment further (they probably can't) but I assume they either modified the layout (perhaps the placement of certain logic was tricky for manufacturing) or manufacturing process to solve the issue.

Better question is when the new chips are going to be flowing out. There are still huge stocks of trays containing 6-Series PCHs sitting in Taiwanese factories. Intel hasn't let my company know if they're going to replace the now essentially defective trays of PCHs sitting in our warehouse.

The sad part is, he wasn't always evil.

The firm expects to see a $300-million dent in first-quarter revenue (since full volume production of 6-series chipsets won't resume until April), not to mention $700 million in total repair and replacement costs.

No real impact really.
