Grand Prix 2 and AMD K6-2 450

by Martin Hugh Roger » Tue, 17 Aug 1999 04:00:00

I welcome comments from anyone who has experiences with using Grand Prix
2 with an AMD K6-2/450.  

When I run the game it vanishes completely at a random moment, though
usually in the first few minutes of the game, and sometimes happens when
taken off pause.  It is evident under both Win95 and Win98.  Oddly
enough the game runs fine at 400 MHZ.  I returned the CPU to my supplier
for checking, who returned it back to me saying that they had run
various tests on it and they could not find anything wrong with it.  The
chip is marked up as an genuine 450.

Is this a CPU incompatibility with GP2 or something else?

Just for completeness, the rest of the hardware I use when reproducing
this test is

-FIC VA-503+ (recommended by AMD)
-128MB PC100 RAM
-S3 Savage 3D 8MB Video card.

Thanks in advance of any comments.

regards
mart

First of all check your cooling. K6-2 450MHz requires very good cooling,
because it only accepts temperatures up to 60C (not 70C as slower chips).
You have to use good cooler and thermal compound between it and CPU. Without
thermal compound it wont work (AMD thermal specs require thermal compound).

  GP2 has problems with CPU's that are <G> too fast... check & see if they've posted a patch.

Well. What makes you think its your AMD?

I can tell you (for sure) the problem is not your CPU.

If anything you've got trob with your video sub-system,
keep in mind AFAIK the only 3D acceleration for GPL is 3dfx glide or
Rendition Verite.

It looks like the secondary power supply (that makes 2.2-2.4V) is no good on
your
board. First, the K6-2 officially requires 2.4V for stable operation, and if
your
503+ board is not revision "1.2 ECN 4503 or EO037 sticker", the 2.4 voltage
may be not strong enough to supply peak currents for 450MHz operations.
You could be lucky to make it work with good cooling, that is correct.
You can also try to jack voltage up a little by installing an additional
jumper on
pins 7-8 (in addition to jumper 3-4), it will give you about 2.47V,
still within max specifications. But if you never used a multimeter, do not
try to
do this, better go and buy a proper board from your dealer who will
guarantee
the MB/CPU combo compatibility..

Good luck.

Just to report that I have absolutely no problem here running GP2 with a
K6-2/380 (95Mhz busspeed, 64Mb PC100 SDRAM).

My system was incredibly unstable under Win98. Blamed this on the AMD, but it
turned out that the DIMM was bad...

Good luck,

JoH

Many thanks for a top tip.  I squirted some heat transfer compound onto
the CPU and refitted the CPU fan, and it has been rock steady ever
since.

Why don't suppliers mention these things!

>Why don't suppliers mention these things!

If one buys boxed CPUs one doesn't need to care about that, because CPU is
already equipped with proper cooling. But if one buys OEM part, he is
belived to be a system integrator and thus know how to do things properly.
If someone buys on grey market then it's his responsibility to do things
right. If he has problems he could however ask on the news and get
answer/tip.

I take your point.  However it turned out that even my supplier was
unaware of the requirment for heat transfer compound when running this
chip - one reason why he didn't point it out I guess!

1. 450 mhz amd k6-2 twice as fast as a cyrix 233????

2. AMD K6-2 or K6-3

3. ICR2/indyfast(dma)/AMD k6-2?

4. AMD K6-2

5. Does F1RS run on a AMD K6-2 ??

6. AMD K6-2 300: Anyone using it?

7. GPL - anyone using an AMD K6-2 333?

8. NFS3 + AMD K6-2 350 == Chunky (?)
