Memory Stress Testing
This memory stress test looks at the ability of the Biostar PT880 Pro-A7to operate at the officially supported memory frequencies of 533MHz DDR2, at the best performing memory timings that the Corsair CM2X512A-5400UL revision 1.3 will support. Note that this memory is rated at 3-2-2-8 timings.
The Biostar TForce4 was very stable with 2 DDR2 modules in Dual-Channel at the settings of 3-2-2-8 at 2.1V. We will now test 2 DDR modules to determine our best performance settings.
This memory stress test looks at the ability of the Biostar PT880 Pro-A7 to operate at the officially supported memory frequencies of 400MHz DDR, at the best performing memory timings that the OCZ PC4800 Platinum Edition will support. This memory is rated for 2-2-2-5 timings.
The Biostar PT880 Pro-A7 was completely stable with 2 DDR modules in Dual-Channel operation at the settings of 2.5-3-2-7, but it required the memory to be operated at 2.8V. We tried several combinations of memory settings at CAS Latency settings of 2, but the board was not stable enough to complete our test suite.
Given the budget nature of this motherboard, it is unlikely that potential buyers would actually purchase top-quality memory. It is not uncommon to see value boards that are tuned for value components, and this appears to be the case with this Biostar board. Our recommendation is that you plan to run more typical memory timings, so unless you already have some better RAM, don't spend extra money getting high performance RAM for this motherboard.

I would say the Asus P5VD1-X is a 10x better option than this board.- PT880Ultra instead of PT880Pro
- Asus doesn't use OST caps
- gigabit lan controller
- space in between the AGP and PCI-E slot so you can actually put two cards
- can be found as low as 50 euro
It would be nice if you reviewed this board too. I used it and it really did good.

Thats the PT880 board I am running now. It does not have voltage mods for the CPU but I was told the next Bios update will fix that. :)Per Hansson - Tuesday, March 21, 2006 - link
Gary, sigh, I whined about this in your Epox review and I'll do it in this one tooThe Caps used on the board for the VRM section are excellent brand by United Chemi-Con, for the smaller caps they used the crap-brand OST that will prolly fail within the boards useful life if they are installed in any high ripple areas, which they seem to be (chipset, memory and expansionslots....) Please atleast provide pictures where you can read the make and model of the caps
Next; PCI-E 4x has low bandwidth; well, compared to AGP 3.0 it is 2.0GB/s, and guess what, AGP 3.0 has 2 GB/s too... So the issue is not with too little bandwidth but something in the implementation...
Most serious is the fact that there is no mention about the fact that the VT8237R does not support SATA2 harddrives, i.e. they do not work at all with it! Only the VT8237R+ support SATA2 properly, this is a design issue in the following chipsets: VT8237, VT8237R, VT6420 and VT6421L

While i know OST caps are cheap and come from Taiwan, still i have to see a blown up one. Asrock is using them from the start and those first boards are still working good for me. Still, better ones are good but OST isn't crap but just worse. Big difference.PCI-E 4x has 2GB/s bandwidth in total, what means 1GB/s per direction. So it can read 1GB/s and write at 1GB/s. Since these stuff are reading most of the time ...
AGP can use it bandwidth in both directions meaning it can read at 2GB/s or write at 2GB/s. But the benchmarks do show that 1GB/s for reading is just not enough for these highend cards.
About the Sata2 incompability. The southbridges you mention do have a detection issue. But any Sata2 hdd can be to Sata1 by jumper. When you do that, they will just work. Actually hdd's from Samsung, ... are set to Sata1 by default and have to be set manually to Sata2 by jumper.
All the lastest Via boards i got from Asus (last month) had the Plus version of the southbridge, so you don't need to bother any longer about it either.

The PCI-E 4x comments have been clarified by RZA79 already. Our features chart and text clearly indicated the VIA VT8237R was a SATA 1.5Gb/s controller. However, I obviously did not clearly state this in the article. :) I updated the Final Words section based upon your comments. In our testing with this controller, our Maxtor, WD, Seagate, and Samsung 3Gb/s drives all worked fine with the jumpers set to 1.5Gb/s. Thanks!!!

I had no idea about the PCIe bandwidth info... Interesting to say the least
And last, I bought a friend a 500GB Seagate Barracuda, it did not get recognized by his mobo (8237 southbridge) I contacted Seagate by phone, the tech said I was supposed to put a jumper between two of the pins, it did not help, so I had to buy him an external controller

From this review, you can certainly see that AMD made a good choice going for an IMC - relying on VIA, they'd always be in second place.Not that VIA chipsets are bad to use, but they certainly aren't the quickest...

Something isn't quite right here. If you want to provide an upgrade path for basic users, start with what they have already:1./ CPU - 478 (this is an intel example)
2./ GPU - AGP
3./ Memory - DDR
And cost/price of the original components (and their new replacements) IS IN THAT ORDER. What's the point of throwing away your most expensive components and recycling only the lowest value ones? Not much really.
The design criteria should be to get maximum gain from minimum investment. And to me that would suggest upgrading, in this order:
A./ Increase memory
B./ GPU
C./ Other software or hardware speed-me-ups
D./ Maybe CPU if you have a pooooor humble one. Either you buy a second hand CPU on ebay, or you might as well start with a brand new up to date platform
Not on the list, would be to change memory format DDR vs DDR2 (since this ain't going to give you any more practial or noticeable speed)
Therefore, for the budget conscious upgrader, what is needed is a mainboard that will allow them to do upgrade A and B at minimum cost. ie a mainboard with PCIe16 and socket 478 and SIX DDR memory slots. (SIX Slots allows the upgrader to use existing too-small DDR sticks and add a couple more)
I believe ASUS and ASROCK did a socket 478 and PCIexpress, but guess what, only 2 RAM slots. Brainless.

yeah bright, 6 dimms unbuffered memory!
