Core2 Aftermath

The squeak was caused by my motherboard being screwed in too tightly (yes, I know that sounds wierd). The instability that I was experiancing was do to my RAM voltage being too low. The default on the mobo is 1.8v the ram I bought runs at 2.2v. Setting it to overvolt .4v fixed her up nicely. It is now quite stable.

I bought an ocz gamexstream 600w power supply thinking that was one of the issues. I was wrong, and now need to resell the nexus one I have. I’m sticking with the ocz just because I don’t want to have to cable the thing again.

My kernel now compiles in 2:20

Power usage: 140w idle 190w loaded.

lyz@core2 ~ $ glxgears
53506 frames in 5.0 seconds = 10701.173 FPS
X connection to :0.0 broken (explicit kill or server shutdown).

core2 ~ # hdparm -Tt /dev/md4
/dev/md4:
Timing cached reads: 5344 MB in 2.00 seconds = 2672.22 MB/sec
Timing buffered disk reads: 384 MB in 3.01 seconds = 127.66 MB/sec

I was getting 148MB/sec — I need to look into this

Kindof operational

I put together all of the hardware components for the new box and got Gentoo running on it.  There’s only one issue..There’s a high pitched squeal on the board somewhere.  Tomorrow, I am going to swap out the processor to see if that helps.  It’s either the motherboard or the CPU.  Really not what I had hoped for.

Most things there were free shipping. I saved a lot on the case because of this.

1 x (140138) Antec Performance One P180B Advanced Super Mid Tower Case (Black) Retail ***Free Shipping*** @ $114.99

Why–Quite case with good style. Separate compartments for power, hard drives, and motherboard. 180mm fans should move a lot of a air and keep down noise.

1 x (80859) Intel Core 2 Duo E6400 Conroe Processor 2.13GHz, 1066FSB, LGA775, 2MB Cache Retail ***Free Shipping*** @ $226.00

Why– Intel Core 2 is smoking AMD right now (check out the benchmarks if you don’t believe me). This is the model right before the big price hikes. Supports virtualization and is 64 bits.

1 x (322341) Gigabyte GA-965P-DQ6 P965 Express Core 2 Extreme/Core 2 Duo 1066FSB LGA775 DDR2 ATX Motherboard w/Audio, Gigabit LAN, Serial ATA Retail ***Free Shipping*** @ $224.99

Why– Will support the quad core cpus when they come out. 800 Mhz memory can be used. Power on by mouse or keyboard. It is also passively cooled witch takes a little noise down. Quad redundant BOIS. This thing was costly though. I wouldn’t recommend just going out and buying one.

Newegg is great for things that are on sale.

VGA BFG 7600GT 256M BFGR76256GTOCE – Retail (Qty=1, Price=$144.99)
Why– It was cheap. Still have to buy Nvidia as the ATI drivers are not that great under Linux. Should be good enough for me.

HD 320G|ST 7K 16M SATA2 ST3320620AS – OEM (Qty=2, Price=$189.98)
Why — The first 3 reviews on new egg said it was quiet. It uses sata 2 technology. It is one of them cool perpendicular drives. I’m planning on running these raid 0.

MEM 1Gx2|CRUCIAL BL2KIT12864AA804 R – Retail (Qty=1, Price=$288.99)
Why — 800 Mhz ram. Good CAS latency and timings. I got a $100 rebate with this so it wasn’t actually that bad.

From endpcnoise.com

Qty Item No. Description Price Ext
— —————– ———————————– ———- ———-
1 PHT-7750 ON SALE- Reg. $39.95- Nexus $34.95 $34.95
PHT-7750 Copper Socket 775 Quiet
CPU Fan In Stock

Why — I really like Nexus products. I read that some people were having trouble fitting huge heat sinks on the board I bought and this one looks smaller and weighs less than the Zalman solutions.

1 NX-5000 SALE – Reg $124.95 – Nexus NX-5000 $104.95 $104.95
500 Watt Silent Power Supply In
Stock

Why — I already own one of these and it powers my server well. The 120MM fan makes it quiet. Not terribly expensive. Did I mention that I really like Nexus products?

Total price was around $1300. That doesn’t include a CD rom drive of any type. I do still have $130 in rebates coming. I don’t think I did too bad.

Mike of netfest.org fame and I and another guy named Tom did some Solaris toying yesterday night. There’s two things about Solaris that just plain rock, Zones and Dtrace.

Zones are a dead simple way of replicating the current environment in a virtual machine. It’s unlike anything I’ve ever played with.

Dtrace gives about any statistical information you could ever want. We ran some example scripts that monitored the size of the disk buffer that programs are requesting. Not only that, but it outputs in nice little text graphs.

I was also impressed by Solaris’s startup system. They replaced the init system beautifully. A nice feature is that when a service is disabled, it is stopped if it is running. Same thing goes for when a service is enabled.

Just wanted to congradulate the Lions on thier great play last week.  Holding the Seahawks to 9 points is an awesome feat.  The offence outplayed Seattle in the 2nd half.  It was a bummer that they still lost.  Gotta get in the endzone boys.
