Change AMD 300meg CPU

Look up Fic 503 somthing mother boards and see if this
is it

if we can identify yor mother board it will help

if you know the maker of the mother board post it

i will be back to check on more info...

Yes, just change the multiplier from 3x to 5x if it's already running at 100MHz FSB.

Yes, that's what he's talking about.

Why not get a K6-2 550 and change the multipier to 5.5x? I have a 550 in one of my machines and it works great. I have the Gigabyte GA5AX motherboard to go with it, and I have never had any problems. Nice stable system.

Thank you for your reply Crashman. The jumper settings that I can determine are: Clock 100Mhz, CPU 90-100Mhz so I think it is safe to assume the FSB is 100Mhz.

we need to identify....

Sounds like my FIC VA 503+ 1.2A MB (great MB). Tom's Hardware rated this MB among tops for o/cing. I was given another rig with the same chipset and K6 2 300. Turned out to be CXT core (which has #26351 (Sharptooth) stamped in gold numerals on top edge of ceramic), and it immediately overclocked to 400MHZ at default voltage of 2.2v, std HS&F.

In addition to FSBs up to 100, the 503+ also has 112 and 124. One of the most popular o/cing MBs around. Personally, I would drop in any K6 III (beats all K6 2s, except + which requires a bios flash). I have a K6 III 400 either at 450 on 100FSB or 448 on 112FSB (latter is better performance). I have 1 stick of PC 133 128MB, or you can use anything from PC66-100. The normal III models are straight drop-in upgrades, until you come to the fastest upgrades, the 450+ and 550+ chips. Again +s require bios flash from FIC JE4330 I think, the payoff being speeds to 550 and beyond. 450+ a better deal because most +s only go to 550.

The III chips are the way to go, because of the large on-die cache vs 2 models . Do some reading, compare some benchmarks. Great MB. Good luck!

P.S. If you don't know anyone w/a MB manual, downloading from FIC could be helpful.

Thanks OWL. Those URL's identified the board as being made by Vision Top Technology and is model Vision S7-MVP3. I sure hope you know of a source for a manual or at least information on that board.

Thank you. Did you go from the K6-2 350 to the K6-2 500 or K6-2+ 500? And regarding the CXT problem you mentioned I will be running 98SE and if it does well will upgrade to XP when it appears. Will that problem still apply?

No, all versions of windows after win98 are problem free. If you did have that problem though, AMD would give you a free copy of win98.

It's July. O the Joy of Summer!

There are non K6-2+/550 cpus. Almost all K6-2+ processors went into laptops. The 550 I have is just a standard 550 and it operates at 2.3v, which your board should be able to handle. And if your board can't handle 2.3v, then just go with the 500, you probably won't notice much a difference.

Great info OWL! I went to the site and was apprehensive at first as the jumpers as indicated were wrong for my board. Pays to read the fine print at the bottom as there was the manual for the version that supported 95Mhz FSB. Looks like I am going to have to update the BIOS!!!!!! Frankly, the description of how to do that makes it scary. It would appear I will have to Flash the BIOS regardless of which CPU I decide to install. I read the article about Socket 7 Triangle and looked at the Processor and Chipset Tables and it appears there is a descrepancy in the core voltages for the K6-III between the two articles. Probably my best bet would be to go with the K6-2/500 (can't go to the 550 because my board does not support 2.3 volts)(jumps from 2.2v to 2.7v). I guess it is about decision time -- your thoughts please.

NO hold on....
what is it set for on (F1-F3, Green

I agree the 95Mhz has nothing to do with it except it identifies the difference between the board as depicted on that site and the actual board I have. Mine is a newer Revision (1.2) and therefore the core voltages and the FSB speeds are different (as well as some of the other jumpers) . You would have to download the manual, unzip it and then print from a .pdf viewer to actually see my board. And the FSB Green jumpers are set for 100Mhz.

I still don't see where you need to update the bios.
it is all set to 100mhz
the only thing i see it to reset jumpers to 5.0
and leave it at 2.1 or 2.2 Volts

If you are talking about Voltage ??
i have run k6-2 at 1.8 to 2.4
and k6-3 at 2.0 to 2.6
so 2.1 or 2.2 no big deal...

If you motherboard wasn't running at 100mhz already then you'd be having problem with your current cpu as that uses the 100mhz bus already. The only settings you'll probably have to change to run a k6-2 500 is the motherboard multiplyer. That will need to go from 3.5 to 5, the voltage settings should be the same and the bus speed won't need changing.

and 98se runs fine with the cxt core amd's without any modification.

I don't think it's a good idea to run the cpu at anything other then the specified voltage, unless your overclocking it.

BTW in case your interested unless you want to run the latest games at maximum res you should find the K6-2 500 (with a reasonable graphics card and about 128mb of memory) should run almost everything quite nicely (or at least mine does).


Your nice new PC might be faster then my 286, but my 286 makes a better door stop

Thank you very much OWL. And my appreciation to all you guys that have offered your help. I will be back when that new K6-2/500 comes in. Momet
