How fast is my sempron for gaming? part II

[konakona]

I have been using el cheapo s754 2800 sempron (256kb, integrated memory controller sans 64bit support) at 275*8 = 2200. Every thing was great except it would crash like once in a month when I leave it idle. Seeing how temeprature wasnt the issue here (never crashed while playing games), I suspected cheap ram I was using, doing cas3@228. I went back and changed the memory divider to run the cpu at 315*8 = 2520 with cas3@210 memory. The system hasnt crashed as of yet with some heavy gaming, so I am pretty confident I found a sweet spot.

What Mhz would this machine be equivalent in terms of A64 and P4 for gaming? My friends are curious and I would want some general guestimate. Thanks.

i dont have the answer, but my athlon xp at 1ghz (i have no idea what it is ) crashes when it finishes loading a page (on the internet), i have a 512stick and 256 stick of pc133 (one is infenion and the other showes up to be AMD on cpuz)

any ideas?

what are your memory timings? try lowering them, mostly its either the speed they are running at or the cas latency setting.

UPDATE : seems to be ok with 2.5 cas. 2 booted fine but would result in random opera & IE crashes.

Since no one else answered, I will give a rough estimation, maybe someone with some concrete benchmarks can verify. First of all the A64 with 512k L2 cache will be about 10% faster in everything then the 256k Sempron at the same speed. So that will give you about 2250MHz A64 speed.

The memory controller built into the cpu gives gaming a huge boost over a conventional P4 or XP/Barton. So I would guess your Sempron would compare to a 3.4-3.6GHz P4 for gaming. Amazing for a $75 processor, I am running two overclocked Sempron 2800+ myself.

You might want to run memtest and prime95 to guarantee stability on your set up.

Well, I just built a 2800+ sempron 64 system for a friend a couple of months ago. With the stock heatsink it would easily do 2.4GHz stable(maybe more...never tried) but with 3 512MB sticks of corsair value ram it wouldn't budge above 1.9GHz. For the money it's an awesome cpu. @ 2.4GHz it was scoring a little lower than a 939 3500+ on different cpu tests.

I would say yours @ 2.52GHz is probably equal to a A64 3500+ 939 in most situations.

thanks for the responses, I was guessing somewhere in between 3400+ ~ 3600+ region. The best part is I got this like last April for $80ish. Funny how the best bang for buck CPU didnt change much in pricing, what a true bargain it was back then

yeah true, but as long as it works for everything i do without crashing once... I guess I will do some further testing, havnt gotten a chance to give it a thorough testing just yet
