Is that the sign of a cheap/rubbishy mobo? |
| 15 |
|
| 16 |
Which is why I'm somewhat pissed off with that motherboard and the shop... |
| 17 |
|
| 18 |
I took in a home-built system - with a £90 Gigabyte mobo - and said "it |
| 19 |
won't boot, I suspect the BIOS needs upgrading". When I went to fetch |
| 20 |
it, they said "it won't boot, the mobo's duff, so we've replaced it". |
| 21 |
They gave me the old mobo back, which I discovered was still under |
| 22 |
warranty so I sent it off ... came back "nothing wrong, we've updated |
| 23 |
the BIOS and it works fine" !!! |
| 24 |
|
| 25 |
Bearing in mind (a) I need SATA ports for RAID, and (b) I want to run |
| 26 |
double-headed so I need two graphics cards, I'm well pissed that they |
| 27 |
charged me about £150 for the mobo (because they had difficulty finding |
| 28 |
one with loads of SATA ports), but as soon as I stick the second |
| 29 |
graphics card in some of the SATA ports stop working! |
| 30 |
|
| 31 |
As far as I can tell the original Gigabyte has sufficient channels to |
| 32 |
drive everything no problem! I won't be using THAT shop again ... |
| 33 |
|
| 34 |
Still. The old mobo will be going in a new case (it wouldn't fit it my |
| 35 |
spare) which will be a Coolermaster with room for plenty of 3.5 drives. |
| 36 |
That'll become my testbed/dev machine, which will probably "break" at |
| 37 |
regular intervals as it stress-tests the raid code. |
| 38 |
|
| 39 |
I've bought a 2/4 port add-in SATA card for the system that's going to |
| 40 |
be our main desktop. 2/4 because it's only got two SATA channels, but |
| 41 |
they can go to either a SATA or eSATA port. |
