 |
|
Hi,
I'm experiencing a weird problem here on a ASRock K7S41GX mobo. I've been using an Athlon XP 2000+ for some time now, and I got myself an Athlon XP 2700+ (AXDA2700DKV3D). The documentation of the main board says that all Athlon XP processors, up to 3000+ are supported, but when I plug the Athlon 2700+ CPU in, it is recognized as a Duron processor running at 2250 MHz. Also, when I check the BIOS I only see that the L2 cache of the CPU is 64 KB big. This is very weird. The K7S41GX mobo uses jumpers to set the FSB frequency of the processor. I first set the jumpers to support 333 MHz FSB but the board refused to boot, then I set the jumpers at 266 MHz FSB, again no boot at all. Only when I set the jumpers at 200 MHz FSB, the board boots
My older Athlon XP 2000+ was running fine when the jumpers were set at 266 MHz FSB, but with the new CPU, the board refuses to boot until I set the jumper at 200 MHz. (btw I'm using here 512 MB DDR333 @ CL 2.5)
I've upgraded the BIOS with the latest version with success but that doesn't seem to solve my problem here. The Athlon XP 2700+ is still recognized as a Duron running at 2250 MHz with 64 KB L2 cache
any thoughts? |

He updated already so there must be typical hardware problem.

yeah, I think so, it operates normal, don't have any stability problems here or weird behavior. I also plugged it on a ECS K7S5A and there it also operates at a 200 MHz FSB, though this is normal 'cause the K7S5A doesn't support this CPU but the ASRock K7S41GX has support for a 2700+, it supports up to Athlon XP 3200+ |

damaged core can work stable but with lower FSB in some cases. If you are not sure check it.

the core is not damaged, I just checked it, it is shiny as glass, doesn't have any bumps on it, the resistors/voltage regulators around the core are also fine, no problem there either

btw, I also have a P4 @ 2.4 GHz here (512 K L2, 533 MHz FSB, Northwood), now my question is: which one would be faster? the Athlon XP 2700+ (2.2 GHz, 64 K L2) running on a 200 MHz FSB, or the P4 running at 533 MHz FSB. I know that the lower the FSB/memory is, the lower the disk caches will be thus decreasing overall disk performance.
I know that the P4 has a lower IPC (Instructions Per Clock) because of it's deep pipelines than the Athlons
Memory on both systems is the same (512 MB DDR333 @ CL 2.5)

I would keep Athlon but only because I like AMD more than Intel. I don't know which will be faster in work. I would test both of them in benchmarks and choose better one.

well, I'll do that, but first I have to find a good CPU benchmark for Linux, wouldn't be much difficult. I only asked because I do a lot of DVD encodings (XviD/H.264) here on my Linux system and I know that the P4's (I hate Intel too  ) are a little better at video encodings

ok, i benchmarked the 2 systems against each other on Linux, here are the scores, keep in mind that the Athlon XP 2700+ runs on a 200 MHz FSB with 64K L2 cache, but it still beats the shit out of the P4 2.4 GHz/533 FSB/512K L2 cache  values are in iterations/sec

Best option is keep AMD Athlon  40-50 USD for very good Socket A mobo on nForce 2 chipset isn't much so maybe it is worth change motherboard ?
