1 out of 5 eggsBad from the start

Pros: it was reasonably cheap when i bought.

Cons: when i took it out install nothing came on not even the power supply unit which i went and bought a new one for i then tried the new PSU with the old motherboard and it worked fine a friend who worked for Dell's Tech Depart. and he said might be the motherboard.

Other Thoughts: very very angry right now.

3 out of 5 eggsIf only it would work like it's supposed too

Pros: Everything I needed to get me by a few more years until I get on the PCIe bandwagon. Has an AGP slot at 8x (upgrade over my 4x slot on old computer) supports Ultra DMA 100 hard drives which my old one is, plus supported DDRII, (which was an upgrade over the DDR in my old system)these three things were key factors in purchasing this kit. Bought as part of a barebone unit over at Tidirect. Newegg didn't have anything comparable at the time and it was a good deal based on specs. Especially since it had everything I was looking for. Plus I could validate the cost to the wife as upgrading and/or replacing my aging 478 system cost almost the same thing as this new kit.

Cons: Motherboard installed physically fine but on boot up ... continually gave me the chcksum error: defaults loaded message. Come to find out this is caused either by corrupt BIOS or dead or dying battery. Tried clearing CMOS (followed Biostar manual instructions) but that just caused a non-bootable environment. Power is getting to system but no output whatsoever. Is it too much to ask that a NEW piece of equipment work like it's supposed too? So that you don't have to do endless hours of research online to try and fix the problem. Or replace parts that are supposed to be working. RMA time and hope for better luck next board.

Other Thoughts: I am writing this review here because this particular board is no longer available at Tidirect for some reason and I am unable to write a review there. I have RMA'd the board and am waiting for the replacement if Tidirect sees fit to do so. Gotta say .. wish Newegg had more barebone options. Would have definately got it from here. Newegg is awesome.

5 out of 5 eggsNo Problems

Pros: Board worked great out of box after usual BIOS setup.No issues at all. Put a P-4 3.0 on it with CORRECT TAC COMPLIANT case for proper ventilation and my CPU runs a steady 22.5C

Cons: So far, No cons. Don't forsee any

Other Thoughts: like the other guy said, the only reason for error are the installer itself. The web sites on the box and all drivers and BIOSes are there!!

5 out of 5 eggsWorks great!

Pros: Good features for the price, worked first time, lol. Like the ddr 2 instead of regular ddr.

Cons: None yet for the product. However I loathe ups. As usuall their 3 day shipping turned into 6 days. At first I thought it was newegg so I payed for rush processing and it was sent out same day. So I've come to the conclusion that the slowness is the fault of ups.

Other Thoughts: I had ordered a pc chips mobo before this one. It arrived d.o.a. so I rma'ed it and sent it back. They had discontinued carrying this product so they sent an email saying they would get back with me. To my dismay, without asking me or offering a replacement, they just put the money back on my card and I had to order another and pay the shipping. First time newegg has ever done that to me. Normally they offer me a refund or another product but not this time.

4 out of 5 eggsSo far so good....

Pros: this was a pretty simple build. used a pentium 4 3.2 and windows xp. and it went smooth. suprised that with a board so inexpensive, i had ZERO PROBLEMS.

Cons: well not sure if its the additon of my kvm switch or what, but even using the bios i couldnt get it to boot with numberlock on as default, thats a small nit pick, but i had to include something

Other Thoughts: VERY SUPRISED, but I will keep a watch on it, if it continues to perform, i will definitely keep biostar, and this board in particular in my arsenal for average computing needs.

2 out of 5 eggsWaste of money

Pros: None. Don't spend your money on this one!

Cons: After working on computers for 19 years, you know after you install a motherboard, you get a sense of something is not right but you ride it out. After 3 months it died. No beeps, just dead....

Other Thoughts: Want a cheap board? Expect it not to last long. Not worth sending back to the manufacturer.

4 out of 5 eggsCheap, 1066 FSB Core 2 Duo compatible Motherboard

Pros: Lots of features for price, especially if you have older AGP video cards, IDE hard drives, and DDR RAM. Makes for a cheap upgrade to Core 2 Duo processor. Works well at stock settings.

Cons: Not a good overclocking board. PCI/AGP bus is not locked, so any changes to FSB will lead to instability of your machine. However, if you're using the E4300 Core 2 Duo, you can get around this with the BSEL to VSS pad mod (google it) which requires minor hardware modification, so it's not really for the amateur.

Other Thoughts: By doing the BSEL to VSS pad mod, running Intel E4300 (Core 2 Duo) @ 2.52 GHz (FSB=280, multi=9). Seems to run stably, but strangely though, Clockgen and Sisoft Sandra no longer pick up the RAM frequency, so unsure what the 280 FSB has done to PCI, AGP, and RAM frequencies. Total cost to upgrade to C2D, including MB, CPU and heatsink less than 2** bucks.

4 out of 5 eggsGreat Board!

Pros: I bought this board for a build for a friend. Everything worked just fine on the very first boot. Support for dual core and the 65nm Celeron D. The onboard video is exceptional.

Cons: None, it gives exactly what it says it will give.

Other Thoughts: For the money, it cant be beat!
