Asus TX97-E

[misha]

I've an asus TX97-E and I upgraded to a AMD K6-2 3D 350. My maximum cpu speed is 333 at
75 x 4.5
How can I make it run at 350 or higher?

thank you

[misha]

I got it!
I'm running 75 x 5 = 375
Theres an undocumented jumper
BF2 = 2/3, BF1 = 2/3 & BF0 = 1/2 = 5x

I've just got it running but I dont know how long it'll last I'll keep you guys posted.

bye bye
Happy at last!

Can't you run it at 100mhz fsb? Then it should go at least 400mhz?

Oh, or do you have pc66? hmm.

Good luck

Mike

My old trusty TX97-E has an 83FSB jumper setting and I've had it running there.

Great Board IMO...used it until the P5A was introduced in the S7 Mainboard arena

Hi,

the SP97 series sports SiS 5597/5598 chipset, officially 75 MHz, usually stable at 83.

If ASUS was generous enough to put 83 MHz capable cache memory on the board, it should run at 83 well.

Then, if you have 4.5x multiplier, this means you have three jumpers for the multiplier. That'll give you eight combinations of jumpering (2^3) and take you up to 6.0x: 5.0x and 5.5x are the two unlisted combinations, and 6.0x is where 2.0x used to be.

Max theoretical speed is 500 then, at 6.0x83. Keep an eye on power consumption though, the voltage regulators on that old board design won't feed a 500 stably.

Get yourself a 2.2V type K6-2/450 or K6-III/450, run it 6.0x75 or 5.5x83, and be happy with it :-)

Regards, Peter

OK I've been running without crashes for a day now, I tried all kinds of programme to test its stabality. mpeg3 mpeg movies bla bla.

I cant get it running at 83hz!.*duhh*
halfway booting into window it'll show blue screen. How fast as anyone actually clock a TX97-E?

I've AMD 350 K6-2 3D, 64 Sdram, Asus TX97-E mobo, Quantum bigfoot 2.1Gb, S3 4mb VGA, Awe64 sound.

thanks.

The Quantum Bigfoot Hard Drive won't work @ 83FSB http://www.sysopt.com/forum/frown.gif

Hi again,

my mistake ... you got a TX series mainboard there. That chipset won't do 75 and 83 right (overclocks peripherals and PCI slots), so you should stick at 66 and to 6.0x66 for most stable operation.

LED, the bigfoot _would_ work on chipsets designed for 75 or 83 MHz operation, as those run the IDE interface at specified speed. Intel's 430TX runs the IDE interface 25 percent too fast when the CPU bus is at 83.

What I wrote about multiplier settings was correct, though.

Regards, Peter

What is the jumper setting for 6X?
will my amd K6 2 3D be able to go
6 x 75 or maybe 6 x 66?

[misha]

I tried to OC I used the 2 x 66 but I couldnt
even see anything on the screen..
it went blank!
my core voltage is 2.1v my next option would be 2.8v.
I'm using k6 2 350, so whats the deal here?

[Strip]

I used to have a TX97-E up to recently. It is very stable @75Mhz (even 83, but my poor memories wouldn't take it.
The board is currently running @ 75*6Mhz = 450, w an AMD K6-2 / 450

I don't remember exactly, but disabling "SDRAM pre-read-something" in the BIOS would make it run. Alsao, there are more voltage settings for this board

VOLTS VID2 VID1 VID0
[These settings were wrong. I tried them yesterday on my old board. I must have mixed up my documents somehow. I apologize for any inconvenience caused.]

As you already know, the K6-2 can use the x6 multiplier from 350Mhz version (some early versions might not). Just set it to x2. There is also settings for x5 and x5.5, I can't seem to find my documents for that though, but it is harmless for the hardware to experiment with those jumpers.

Also, check out CTemp, hardware monitoring utility: CTemp homepage (http://hem1.passagen.se/strip/prog)

My ASUS TX97-E does 83FSB and I have owned 2 bigfoot HD and niether did 83 on that Mainboard. TX chipsets will do 83bus not to mention 75, as I have owned 2 of them that did!

[LED]

PS... I think the mutipliers are as follows:
5X=BF0=1&2, BF1=2&3, BF2=2&3
5.5X=BF0=1&2, BF1=1&2, BF2=2&3


and the PCI/IDE speed is 1/2 of the FSB.

[misha]

Thanks guys

I set the jumper to
5.5 x 75 = 412.5

voltage to 2.5v

I got myself a bigger heatsink and fan
the jumper setting is

BF2 2/3, BF1 1/2 & BF0 1/2 = 5.5X

voltage setting is

VID2 1/2, VID1 2/3 & VID0 1/2 = 2.5v

my cpu temp is running at 42ºc with rain on
without rain it'll go up to 47ºc

strange thing is my bios reads 400mhz
directx 7 reads at 416mhz, which is true?

I'll keep you'all posted...

cheers

Congrats http://www.sysopt.com/forum/wink.gif...The D7X is correct as the BIOS on your Mainboard is reading @ it's Max. You can check ASUS site to see if there is one upgarde

[misha]

What is the safe limit for a cpu to run?
when I play quake 2 the temp soar up to
55ºc and still going.

[Strip]

Normally the CPU just stops when it's getting too warm. Frying an AMD is quite unusual (I've never heard of anyone) but I believe that the core should not get warmer than 80°C according to AMD spec.
I'd say that you are pretty close to the limit with 55°C, but as always, there are huge differences between different chips. My K6-2/500, for example, refuses to do anything over 40°C.
Also, overclocking makes the chip more sensitive for heat.
The cooler - the better. That's why most (many) overclocked computers sound like an aeroplane http://www.sysopt.com/forum/wink.gif
Put it in the fridge.

I was made aware that most ASUS TX chipset boards contain the same jumper blocks (TX97, TXP4, TXP4X, etc..). I have an ASUS TXP4 on another machine and the board have performed quite well over the years. From a Intel 233MMX, I decided to extend the board's capability by getting an AMD K62-333. Thru a posting I found while back, It indicated that the board had an unused jumper block (BF2) that I have to use in order to get the 5.0x clock I needed for the 333Mhz to run, as well as a recommended voltage setting that were not on the original manual. Apparently, regardless of board revision this BF2 jumper is your key to using the faster K6 CPUs, so if it exists on your TX board, you're set to use the board even up to 400Mhz on the 66Mhz bus. It's found in between the BIOS chip and the CPU socket. The TXP4 board can also use PC100 SDRAM. I personally would not overclock the K62 on these boards higher than a 66Mhz bus since anything higher would overclock your PCI bus too, and you risk damaging to any cards on the slots. You also need the 2.2 volt setting that AMD recommends for these CPU's. The K62-333 is overclockable to 366Mhz on the same board and can be used as a 350 (3.5x 100) on a board that has the 100Mhz bus setting. I have used these settings on 2 older systems that runs 24 hours non-stop, that's why I can say it's that stable. For the price I got it for, I am very pleased with the flexibilty, and the stability. I used a PC Power and Cooling "CPU-Cool" Z1 fan/ sink compound. (keeping your temp down is the major key to stabilizing the CPU.) I also tried an oversized fan /sink available at PC shops for around $12.00 with no problems although you may get better results with aftermarket cast aluminum types.

These are the jumper settings on the TXP4:

**for 5.0x clock (330 Mhz)
BF0=1+2
BF1=2+3
BF2=2+3

**for 5.5x clock (367 Mhz)
BF0=1+2
BF1=1+2
BF2=2+3

**2.2 volt setting
VID0= open
VID1=1+2
VID2= open

to use a K62-400 on the same type boards:

**for 6.0x clock (396 Mhz)
BF0=2+3
BF1=1+2
BF2= open

Flashing the BIOS to newer revisions only shows you an updated "K6-2" identifier on boot up but I doubt if it improves overall performance.
