O/cin a 4800se

[Swafe]

Hey, got a 64mb ge force 4 ti 4800se

mines a gainward so i imagine it should clock ok, runs 275/513 default

what have people got ? and whats likely? also is there anything i can download to check the temp of it? so it dont burn all the way to hell

ta

[Swafe]

well ?

[Stoo]

I've got a Radeon, so that's not gonna help

[catattack]

Well... Before I freaked and though that the flashing monitor when windows started was bad, it was oc'd to 25mhz on memory and core from defaults. I was still going the distance with it so i'm sure I could of gotten another 10mhz.

P.S. You guys think MSI Geforce 4 Ti4800SE is an alright card? Ok lol, on a scale fom 1-10!

Unfort your 4800SE is little better than a 4200 despite the impressive naming. Technology is the same and basicly only clocks speeds dictate the perf diff between the GF4TI cards. Here's where the clocks should be...

4200_128MB = 250/444 (o/c = 290/500)

4200_64MB, 4200-8X_64MB & 4200-8X_128MB = 250/500 - 250/512 (o/c = 290/550)

4400, 4800SE = 275/550 (o/c = 300/620)

4600, 4800 = 300/650 (o/c = 310/700)

As you can see your 4800SE is no better than most 4200 and is pointless as soon as o/c'ing comes in to it, your 513 RAM means your o/c will not be inline with 4400/4800SE cards. Clock speed variation is not uncommon and Gainward set their std cards intentionlly lower to make their Golden Sample cards look better than they actually are. Another big blow is 64MB as it is becoming increasingly limiting and the perf hit is very notable. Even without the perf hit that comes from relying on system RAM for texture storage there is a 5%ish hit on 64MB GF4TI cards making your 275/513 roughly equal to a 260/487 128MB card and a LOT worse when more than 64MB gfx RAM is needed.

Even so it isn't all bad as your card still packs a mean punch and is actually as fast as Rad9600PRO and GF-FX5600ultra only losing out to them in AA+AF and DX9. No o/c'ing is certain and the above is only rough guides, I just can't see (with such low default clocks) Gainward putting decent RAM on there which is the most important part of GF4TI o/c'ing (although the longer 8 layer design is advantageous).

well i got it to 295/540 no probs and did 3dmark 2001

just scareed of doing any more incase i burn it out as i duno how hot its running, anyone got any good ideas of how to tell when to stop?

[Tom]

my 4200 is @ 300/600 and itll do more i bet. Get artifacts at 650 tho

[blockers]

My gainward ti4200 64mb goes to 313 core and 567 mem. I desperatly want 600mem! but my TT copper cooler didnt manage it.

Still far overclock

[Swafe]

i know that when i get artifacts, im overclockin it too much

how long with artifacts till it does some hardcore damage? also whats a decent speed i could clock it to, to see if it runs ok, i cba doin it in 1mhz steps, and i need some more powah

[Tom]

my ti4200 is @ 600/300

[Swafe]

290/570 it quit half way thru 3dmark, but could because i upped my cpu by quite a bit as well

i reckon gf4 should be ok, so ill try again later

[blockers]

Well the core wont cause atifacts. So just raise that till i crashs out of games to the desktop. The mem will go further i think. Mine has 3.8ns ram chips. so if u have that then just use riva tuner to 567mhz

Im sure it will be cool....hehe

Also what cooler u got? try and get a 80mm fan on the back of it (opposite side to core) because mine gets damn hot there.....

have fun ocing. Just leave the CPU at stock and put the graphics up. Then u know what is limiting. Also put the AGP frequency to 80, and up the volts.

Just dont break it......

Last but not least. There is a drop off point. run 3dmark each time just to check it works. the mem clocked too high will cause atifacts. the core will cause a drop off in score.

[Swafe]

thanks

hope i dont kill it, aparet from that should be ok

running stock cooler
mainly because i cant afford a new one / havnt got time to fit, but should do the job ok-ish i only play games for 1 hour at a time, dont play non stop all day like the olden days

You know you're a little too far when you get artifacts or instability (freezing, lockups, crashing, quitting to desktop). First just take the RAM as high as it will go, then back off about 10mhz for long term stability. Then take the core higher and find its limit, again back off from it for the long term. So if the core could do 295 and RAM 550 then you'd want to use something like 285 core and 530 RAM. ALWAYS use small steps, 1mhz is OTT but 5mhz is a good step up.

Do this with stock cooling as there's rarely much improvement anyway, esp for GF4TI cards. Also DON'T USE VOLTAGE OR AGP INCREASES as these will seriously over stress your card needlessly and usually hamper the best o/c's, inhibit stability and added voltage will produce a LOT more heat and stands a chance of taking out your card if not mobo too. For gfx cards leave the voltage and AGP speed alone! Having an AGP speed of 80mhz is NOT going to help you as that refers to the speed out of the gfx port NOT the speed the card runs at in any real sense. As seen AGP4x (4x66mhz) is not limiting even for the top end cards so 4x80mhz (or even 8x80 for AGP8x) is a total waste.

The risk to your card is abosolutely tiny IF you take small steps, find the RAM then core limits and then back off a little, don't run too near the limits and seriously avoid any over-volting, AGP driving or needless raising of the AGP port. As said it is very wise to set other o/c's (CPU, FSB, RAM etc) back to default so you're only dealing with the gfx card itself.

[Swafe]

thanks mate, ill do that, see how far the ram goes

artifacts, do they just appear when i hit a certain point? or will i have to play e.g vice city for 10 mins for the card to get stressed, heat up to its limit and show up ?

[Austin]

Should be very evident within the first minute or two. Most people use 3Dmark but it's up to you as any remotely modern game should be fine.
