Rig Research October 2001

Goal

The goal of this research was to find a suitable upgrade to my current server. The existing box was my first home built computer, cobbled together almost four years ago. It has done a fine job all this time, but is in need of replacing because of all the mad perl and game servers running on it day and night. Prices of chips and memory is at an all time low, and it doesn't look like there will be much more to look forward to until next year, so now is as good a time as ever. Since this is a server, and not my primary machine, I want to keep the price as cheap as possible. Following is a catagorical analysis:

Note: The computer industry moves very quickly, so the majority of this information will most likely be out of date by tomorrow. I keep it around for my own historical reference, and also the slight chance that it may help out someone like you somewhere, somehow.

Motherboard

  1. KG7-Lite for $117.99 from The Overclockerz Store
  2. KG7-RAID for $154.99 from The Overclockerz Store
  3. KG7 for $134.99 from The Overclockerz Store
  4. Epox 8K7A for $119.99 from The Overclockerz Store
All of these motherboards are fairly cheap, very fast, highly rated, and accomodate a 1 - 1.4 GHz Athlon. They are also all sport solid AMD761/VIA 686B chipsets. The $17 more expensive KG7 only buys four DIMM sockets instead of KG7-Lite's two. The KG7-RAID is attractive because it incorporates a Promise RAID controller, but I have yet to take advantage of the RAID support in any of the other rigs I have built. I'll dump the $37 into memory instead. The Epox board seems to be most like the KG7-Lite, but it has jumpers and switches instead of Abit's SoftMenu, so the price difference is not that attractive. I've had good luck with Abit before, so I'll stick with them this round.

I was excited about the nForce motherboard, but the reviews indicate that this is a first good attempt, but waiting for their second offering might be a good idea.

The new VIA KT266A chipset has been getting good reviews [accelenation, AMDWorld], but it was only available on prototype motherboards at the time of this analysis.

Here are some positive forum comments of the KG7.

Processor

  1. Thunderbird 1400 AYHJA Y-Unlocked for $124.99 from The Overclockerz Store
  2. Thunderbird 1400 for $119.99 from The Overclockerz Store
  3. Athlon 1.4 GHz 266 FSB OEM AYHJA Y Stepping for $129 from iComPZ
Only AMD chips were considered, because we all know that the current Pentium IVs suck. I hope this doesn't require much elaboration. The AYHJA Y Stepping can be overclocked to 1.7 - 2.0 GHz, so the $125 price is quite a good deal.

Cooling

  1. Alpha Novatech PAL 8045 and Delta 68.5CFM fan for $58.98 (39.99 + 18.99) from Plycon Computers (C/W 0.23)
  2. Swiftech MC462-A with fan for $79.95 from Swiftech (C/W 0.14-0.20)
  3. Thermalright SK6 8K (60mm C/W 0.18)
  4. Zalman5K
  5. Cooler Master CB5-6G52 8K

The new Alpha PAL 8045 compares very nicely with the top shelf Swiftech MC462-A, but is cheaper. Overclockers.com also digs it. They have another page of data that report reasonable C/W even with a slower, quieter fan. Quiet overclockedness is good.

FanDimensions (HxLxW mm)Voltage VCurrent ARPMCFMdBA$Price

Enermax Thermal Controlled Fan80x80x25120.231800-310022-4018-3410.99

Fan Performance provides additional fan benchmarks.

The Enermax Thermal Controlled Fan seemed like a good idea, but unfortunately it is geared too hot.

I have chosen the more powerful fan with the intention of dialing down the volume with a rheostat. Apparently blowing is quieter than sucking, but C/W drops about .02. For an idea of how dB is percieved, here is a nice article from Papst PLC.

These venders did not make the cut, but since I researched them, they are listed as well.
Plycon Computers seems to have lots of data, lots of options, and good prices. I hope their service matches their site.
iComPZ sells the PAL 8045 for $38.95 without a fan.
2CoolTek sells the PAL 8045 for $50 with a fan $40 without.
Outside Loop Computers sells the PAL 8045 for an expensive $64.

[23nov2002 update] I purchased 2 Papst 80 x 25, 3 Pin, 26.5 CFM @ 19 dBA, 2050 RPM, Fans for $19.99 each from Plycon Computers today.

Memory

  1. OCZ Performance Enhanced PC-2400 DDR SDRAM 256MB for $49.99 from The Overclockerz Store
  2. Crucial 256MB PC2100 DDR CL 2.5 unbuffered, non-parity, 2.5V, 32Megx64 for $33.29 from Crucial Technology
  3. Kingston 256MB 266MHz DDR RAM for $51 from iComPZ
I have had purchased lots of memory from Crucial with no problems and extremely cheap prices. However, I have seen many overclocking forums talk about OCZ being so much better than Crucial that I want to give it a shot. $15 more expensive, unfortunately.

[26dec2001 update] The memory I got from The Overclockerz Store turned out to be defective. Diagnosing such problems with all new equipment sucks hugely, and I was forced to run out to Fry's for cheap-o memory to do so. Luckily, the cheap memory seems to be overclockable, and The Overclockerz Store processed my return.

Case

  1. Antec SX1040 Server Case with Enermax EG465P-VE Power Supply for $142 (129+13) from Directron.com
  2. Antec SX1030B Black Server Case for $98 from Directron.com
  3. Antec SX1040 Server Case for $129 from Directron.com
  4. Lian-Li PC70 All-Aluminum Case with Enermax EG465P-VE for $219.00 (129+90) from Directron.com
  5. SuperMicro SC750A Full Tower Case with Enermax EG365P-VE for $230.00 (159+71) from Directron.com
  6. Enlight 7237 Mid-Tower ATX Case with Enermax EG365P-VE for $95.00 (53+42) from Directron.com
  7. Unnamed All Aluminum Case for $124.99 - did not research

The Antec SX cases are popular in the AMDMB Forum and Maximum3D. I'd prefer the black SX1040B, but I could not find it in stock. The only difference between the Antec SX1030 and SX1040 is the power supplies: 300W PP303XP vs. 400W PP412X, respectively. These power supplies are probably adequate, but upgrading to Enermax is not too costly. See the power supply analysis below.

The Antec SX830 and SX840 Workstation cases are the same size as the SX1030 and SX1040 SOHO File Server cases, but they have less drive bays (and bay cooling) and shift the cooling from back to front.

The Lian Li cases are sexy and light. But the extra cost for something that might end up running in a closet is a bit silly. Maybe for the game machine I make later.

I'm just sick of low end cases, so I will pass on the Enlight 7237.

Power Supply

  1. Enermax EG465P-VE 431W Power Supply for $90.99 from Plycon Computers
  2. Enermax EG365P-VE 350W Power Supply for $68.99 from Plycon Computers
  3. OCZ 300W AMD Approved Power Supply for $26.99 from The Overclockerz Store
  4. OCZ 350W AMD Approved Power Supply for $51.99 from The Overclockerz Store
  5. OCZ 420W AMD Approved Power Supply for $79.99 from The Overclockerz Store
  6. Enermax EG651P-VE 550W Power Supply for $169.99 from Plycon Computers
  7. Leadman 500W Power Supply for $64.99 - did not research.

The FC version of the Enermax EG465P-VE provides motherboard controlled sleeping, not something very useful for 24/7 servers.

[26dec2001 update] After the fact, Jack has informed me that Enermax is not, in fact, the best power supply to purchase. He had a heck of a time getting his rig up, and discovered he was pretty much pushing his Enermax to the limit. I have had a CD player fry, so I am a bit leary myself. Jack recommends PC Power and Cooling now, so perhaps my next purchase will include one of their more expensive units.

[22apr2002 update] The Enermax power supply finally kicked the bucket. I ordered a PC Power and Cooling Silencer 400 ATX for $169.15 today.

Hard Drives

  1. Western Digital Caviar WD800BBRTL 80GB UATA/100 7200RPM, 8.9ms seek, 2MB cache for $129.95 from Fry's (with $100 rebate)
  2. Seagate Barracuda ATA IV 60GB UATA/100, 7200RPM, 9ms seek, 2MB cache ST360021A for $149 from Hyper Microsystems
  3. Western Digital Caviar WD1000BB 100GB UATA/100, 7200RPM, 8.9ms seek, 2MB cache for $269 from Microchip Computers (local shop)

I chose the Western Digital drive simply because it was so cheap. I hope the rebate doesn't screw me, however.

Storage Review has great analysis of hard drives.

Accessories

The 5W rheostats are for fan rate control to tune fan dbA vs. cooling overclockability. One of these rheostats can control at most 2 Panaflo L1A series fans. I am going to rig one rheostat up to the Delta HSF to dial it down without compromising stability or lifespan of the Athlon, because this will undoubtedly be the loudest component of my computer. I will of course wire a second one to the 120mm case fans. For calculating what power/resistance rheostat to use, here are some equations that may be useful.

And remember, you can always find newer, better prices using Price Watch. Make sure that you verify your venders using ResellerRatings.

Fan Control Circuit Footnotes

In the future, I would like to make a temperature sensitive fan speed controller using one of the following methods. Apparently Pulse Width Modulation is the way to go with a DC fan because it has a very high inductance.
