Suggestion/advice for OCing AMD K6-2 500

[Genki]

I've done with my taxes and I'm expecting almost a grand back from Uncle $am so until I get my money, I figured I might as well squeeze my old PC for every ounce of performance.

I have an AMD K6-2 500 on a Gigabyte GA-5AX mobo. It's running at 500Mhz, 100MHz bus, 2.0v core, 5x multiplier

Since the Socket 7 and 370 is on the verge of joining with IBM XT and Socket 5 in the obselete realm, I really have no reason to keep or preserve my computer. The best I can figure I could bump to 600MHz (6x multiplier) but I'm not sure about the voltage. Are one supposed to increase or decrease the voltage?

Also would there be any problem if I up the bus speed past the 100MHz? (maxes out around 145 but no standard speed above 100)

If the CPU or mobo blows up, I can blow my refund for a new one. After all it doesn't have anything else good (2MB Diamond S3 video card, 16 bit ISA sound card that sometimes doesn't work right under Windows, and a cheapo no name SCSI card that came with my scanner) All I'd have that are worth keeping is that 30GB hard drives, printer, and scanner

For around a grand you could put together a good solid system on the socket "A" platform, with plenty of upgrade paths for the future. For what it costs to upgrade an older system with SIMMS, ATA33 etc, and you'd be replacing most of it anyhow. You'd still be stuck with old chipsets, BIOS etc. Case in point, 72 pin fast page memory, 32MBs costs somewhere in the $75.00 range, whereas 256MBs of generic PC133 will run you about the same, eight times as much memory.

I'd suggest something like this;

700 to 850MHz DURON or T-BIRD, can be found for about $75.00. ASUS A7V133, or something similar from ABIT etc, around $150.00 with sound. 256MBs PC133 generic RAM $75.00. NEW mid tower ATX case with 300W ps about $70.00. 32MB Video card near $100.00. Modem or NIC $25.00. Reuse your existing floppy and CD ROM, upgrade in the future as needed.

There you go, a system that should get you somewhere real close to 1GHz for less than $500.00, with plenty of room to upgrade in the future.

The K6-2 processors never clocked very well. I also have the 500, and the best I ever got it to was 550 with the jumpers set at 5.5. But, I have a question...why are you running it at 2.0 v...all specs I have ever seen for these were 2.4 volts, which is where mine has run sence `98. If you do decide to clock it, do it in small increments at a time...I wouldn't advise a 100 mhz jump at first...go for 550, and you probably have to bump the core v up a tad then as well.

They also run quite a bit hotter when clocked, so don't try it with the stock AMD HSF..

Kick The VCore Up To 2.20V Like Mine!

While it was never in the class of the old celery 300 for overclocking, the K6-2 isn't really all that bad either. Unfortunately, the 500 is getting near the maximum yield for that .25 micron chip. Still, with good cooling, 550 should be no problem, even at standard voltage (which is 2.2, not 2.0). To reach 600 you will certainly need to up the voltage. Upping it to 2.4 poses no threat to the chip at all, and it is common to see them running at 2.7 (remember your cooling). I have a 450 that runs just fine a 550 (2.4).

Just as important will be increasing the fsb. K6-2 systems really seem to get a good performance jump with an fsb overclock. I would underclock the chip and jack up the fsb to see how high I can get it. This will be limited by the other components of your system. Once you find your max, I would play with the multiplier, trying to keep the fsb as high as possible. 5.0x110 (550) is a more productive overclock than 5.5x100 (550).

Good luck.

Before I chipped the core on my 500, had the FSB @ 112,Mult 5.0 = 560, C/V @ 2.8. 36C temp.Jetway mobo. 600 but not stable enough.

my k62500 used to run at 2.0v (2.2v is standard,2.0v is standard on k62+) but i had to boost it to 2.4 to get 550. i only got to see 600 on screen for coupla secs at a time. had a jetway 530bf mobo

I still have a K6III+ 450 @ 600MHz. Great for the kids, they pound on it all day and it still starts in the morning
