New Gigabyte Motherboard challenge (!)

  GibsonSt19 13:50 21 Sep 03

I've just bought a Gigabyte K& Triton Series Motherboard (GA-7NNXP), with an Athlon 2800 processor, 1gig of ram and a shiny new graphics card.

I put the thing together yesterday and everything's working OK apart from one thing.

The processor is being shown as a Athlon 1250. Now I've amended the BIOS accordingly to show a resultant FSB speed of 400mhz however it's still showing as Athlon 1250.

At one point yesterday I flipped the CLK_SW jumper on the motherbaord which then on reboot displayed the processor as an Athlon 2800, then after a restart I can no longer see anything on the screen (i.e. the monitor LED remains flashing amber). When I flip the switch back, everythings fine, but only as Athlon 1250.

Any ideas? Having spent a wad of cash on this I want it to be operating at its best!

Your board has a dual bios doesn't it. I dont know but maybe it needs to be done in both.

I think Dual bios is more to do with flashing your bios, if you do it wrong the system loads the previous bios from the backup.

Have you set the jumper CLK_SW to auto, also in your bios under Advanced chipset features is your fsb set to 133 or 166mhz ?

  Rayuk 15:37 21 Sep 03

Your fsb should be 166 for the 2800+ and unless you have PC3200 memory you shouldnt have anything set at 400[200]
Check in advanced chipset features for settings

I do have PC3200 memory, so does this mean I should leave the CLK-SW to AUTO, and choose an fsb of 166? I don't really want to be forsaking any memory power just to keep the system recognising the processor as a 2800+, especially after paying for the PC3200.

Any ideas?

I'm just about to give the setup above a try.

See you on the other side.

Thanks for your help there guys.

Eventually, I had to set the FSB to 166 in the BIOS, and select ON for the CLK-SW switch. The PC reads the processor as Athlon 2800+ and the correct amount of ramm (1gig).

Can I be sure that setting the FSB as 166 is not decreasing the PC's power from its potential?

The 2800+ is a 166[333]fsb cpu
You can run your memory at 200[400] if you wish.
Although it seems as though running the cpu and memory fsb in Sync is the best way using the nforce2 motherboard.

I too have a Gigabyte K7 Triton motherboard v.GA-7N400-L1 (similar to your model) which I have recently upgraded to. I also have DDR PC3200 memory ( 1 x 512) capable of running at 400mhz but with a lower spec athlon than yours - the XP2400 running at 266mhz. Due to a problem I am having with games (see "picture and sounds stutter and freezes in games" - posted in the forum today), I too had occasion to enter the bios and set the FSB from 133 to 200 to give 400 on auto. Same as you I got a black screen with flashing led on button but nothing else. I reset the jumper on the motherboard to "off" and rebooted. The computer came on and I re-entered the bios and reset FSB to 133 (yours is 166). Now just below that in the bios is the memory frequency which can be set to 'auto' or 'SPD'. Auto gives me 266 (yours 333) and SPD gives me 400 memory speed. I have found that SPD works best with a slight improvement over auto. So - leave your jumper to on (auto), set the FSB to 166 and alter the Memory frequency to SPD to give you full memory speed.
If you get any of my problems with games after reading my posting as I have done everything else to solve my problem except change this type of motherboard I would be interested to hear from you. Good luck.
