    Question Overclocking my 128MB Ti4200

    I have a Leadtek (wrap around heatsink thing) Ti4200 with 128MB RAM (the slower stuff IIRC ). Firstly, is it worth replacing the GPU cooler on it and adding ramsinks, or should the Leadtek heatsink be good enough? Secondly, is it worth replacing the Leadtek BIOS with a refrence nVidia one (what sites are good fir this?). Thirdly, what clocks should I be aiming for?

    And lastly, is it worth trying to clock it?

    Cheers

    Most 4200_128MB which use the slower clocks of 250/444 can often achieve around 280/500 and often higher, big perf gains. Stock coolers on all 4200 is more than enough, replacing it and using good compound is unlikely to yield more than 5mhz extra on the core. As for RAM sinks the 4200 never seemed limited by heat, little more than jewlery IMHO. Of course o/c'ing voids your warranty but it could fail from some other unrelated fault, if you mod the card (fan or HS) you guarantee they won't even look at your card. Flashing GF4TI BIOS is very risky and IMHO pointless. Save yourself some time, money and hassle and just try o/c'ing the card as is.

    There's no sure o/c but VERY few 4200 struggled to hit 275/500 which is still 5% behind a 4400/4800SE, you'll have to take small steps up and test to see what's stable.

    ditto..

    dont play with bios. You can oc with coolbits registry add on.

    Also, a lot of people were hitting close to 300Mhz on the core.
    and 500Mhz on the memory is probably a good goal.

    Anyway, overclock one at a time to find the limit of each by itself.
    Then try that combination of the 2 at the same time.... you may need to back down a few Mhz from both for stability together.

    P.S. I had a leadtek GFti4600 that hit 320/720.... but that was a different card w/ different memory chips!! Same big ass heatsink though

    My MSI 4x ti4200 64mb has been running at 300/600 for 8 months now On stock cooling too, the reference heatsink.

    I wanna try overclocking my own Ti4200..... Stock is 250/550 (clock/mem) but most ppl have it running at 320/690 no probs.

    Card = Albatron Ti4680 Turbo running 128MB of 3.3ns memory

    yeh i have an albatron ti4200 (sadly not p, and not turbo) running at 300core and 600mem (320core and 620mem for benchies but its note extremely stable at those clocks).

    good luck with the o/c

    I wonder how far I could push my GF 4200 .... specs in the sig...
    TBH I have never attempted to OC a GPU.
    Any suggestions how to approach it ?

    I have one of them, got it running at 285/650 at the moment, sadly the core doesn't wanna go up anymore.

    Its weird that Albatron has underclocked the memory as standard tho.... 3.3ns = 606MHz IIRC and they run it at 550

    my ti4200 leadtek doesn't clock much I think
    last of an old line before they brought out the 8x versions
    4ns memory so it's maxed already (maybe 5..not sure)
    if you have 3.3ns memory you're laughing!

    My old Leadtek 128 clocks to 320/550 with artifacts (useful only if you want leet bench etc) or 300/525 stable 24/7

    That was about par for the course for people who bought 128 leadtechs [usually from OCUK] over a year ago.
    And lastly, is it worth trying to clock it?
    Hell yeah. Just stick riva tuner on.

    To o/c just install soem tweaking sw (Rivatuner, Powerstrip etc) or the simplest Coolbits Registry Tweak. That shows you your current (stock) clock speeds and allows you to force them higher. So you simply raise the RAM 10mhz at a time and see if you are stable by running 3Dmark2001SE (no artifacts etc). Keep adding 10mhz testing each time until you find instability and then you can use smaller increments to find the abosolute max. However since it's best to back off around 10mhz from the absolute max o/c it really doesn't matter that much. Leave the RAM near the max stable o/c and then repeat for the core. GF4TI along with most modern gfx cards make good gains from EITHER core or RAM increases so I rec RAM first as the core is the one which gives off more heat etc, better to push your RAM a little mroe than your core IMHO. You have to test your own individual card as every single card is different even if of exactly the same brand and type.

    Richie Albatron underclocked the RAM by default so as not to pi$$ off nVidia. If they ran the card at 250/600 or 270/600 it would have been decently faster than the 4400/4800SE. Since most could o/c to around 300/680 they easily achieved 4600/4800 scores. That is the 'P Turbo' Albatron though which used the 8 layer design and fast BGA RAM, they were intended for those who knew their stuff esp o/c'ing and hence stock perf was largely irrelevant. The Suma Special Edition was another great example, also Asus Deluxe but that was not usually quite as good.

    The early 128MB 4200 used slightly slower RAM and RAM clocks. All modern 4200 (-8X) should use the slightly faster RAM and RAM clock and therefor o/c a little better. The 64MB cards though still very good offer slightly lower perf per clock speed so even before the extra RAM is used by a game a 4200_64MB @ 300/550 would be roughly the same speed as a 4200_128MB @ 300/500 so don't despair if you have a lower RAM clock on the 128MB version. When more than 64MB is needed (still not very common) the perf drop is pretty significant making a 4200_64MB @ 300/600 perf pretty close to a 4200_128MB @ 250/444.

    >The 64MB cards though still very good offer slightly lower perf per clock speed

    Depends upon the software. A bit like anything above 128 system ram making virtually no difference to 3Dmark 2001. This time last year there were very very few games that gained the benifit of >64meg... most of those that did (some mmorpg's etc) didnt ever feature in the perfered bench mark sweits of the time. They tended to have to roll out the Jedi Knight 2 bench to prove the difference between 64 and 128 did actually exist as a potential to many future games.

    In practice the 64 meg's faster ram over the 128 Ti4200 cards (pre 8x 4200's) still almost made up for the smaller vid cahe size even on games that benifited from more.

    .... basically the 64 meg card was an all round better card than the old pre 8x 128 4200. I know you dissagree with me on this Austin

    No problem with disagreeing, in fact it is very healthy and useful. There's no doubt it was a close call back when the 4200 was first introduced when deciding between 128MB @ 444mhz or 64MB @ 500mhz. Bottom line there was no bad buy, both cards were great at stock and o/c'ed very well indeed and offered perf very close to the super expensive 4400/4600 when o/c'ed.

    The 13% faster RAM clock on the 4200_64MB only equated to 1-2% in actual perf. At the time I rec'ed the 128MB ones as they offered better future proofing, cost very little extra, would really shine when 64MB became limiting and would sell on much better when the time came. The GF4TI were designed to have a perf increase from having 128MB even when half of it wasn't needed, the Rad8500 were also designed like this but the GF3 and Rad9000 for example weren't, they only gained when more than 64MB was needed. Gains were still very small but definitely there.

    Roundup of 4200 cards and esp shows 128MB vs 64MB!

    http://www.techreport.com/etc/2002q3...m/index.x?pg=3
    4200-128 clocked to 250/500 to isolate only the diff the RAM makes, helps to see what games benefit from the extra RAM.

    Of course it's of very little relevance now as all modern 4200 (-8X) should offer 500-512mhz RAM, making the 128MB the clear choice. However the 4200 with 64MB are still great cards and are better than GF-FX5200, FX5600, Rad9200 and Rad9600.

    Thanx for the advice man !
    As soon as I get home I will try to follow your instructions on OCing my 4200 !

    I'll chime in quickly on that subject.

    The 128Mb only helps in situations that the card cant handle anyway. Like at 1600x1200 + AA its gets a few more fps but both are at slide show rates.

    Its like the 5200 "boasting" dx9 features but runs them at 3 fps!!

    Ok, I may be exaggerating at little bit, but you get the idea.

    I think 64Mb is fine for a ti4200. once you get to a 9600, 5700 or better you should have 128Mb of ram. Anything below that struggles too much with that much frame buffer.

    P.S. I think they are doing it again 256MB isnt really needed yet on this generation of cards. They are just trying to make more money/justify a higher price. And add more "features"
