HELP on 7800GT Overclocking

post #1 of 11
Thread Starter 
Hey guys,

Just overclocked my Asus 7800GT

just checking if you think this is an alright speed
3D Clock: 462mhz
Memory:2564Mh which i presume means 1.282Ghz?? Correct me if im wrong
please let me know if this is a good clock speed

also the guy i bought the PC off at the computer store told me that the Nvidia cards are designed to with-hold a temp of 100 degrees celsius.. is this correct???

one last thing.. im thinking of upgrading my card to an 88 series but i heard of the new 89? is it really worth spending the extra on the GTX or is it not worth the money?

thanks guys

ummm

yes the mem is at 1.2.. but its (effective) ddr clock is 2564. I would go for raising the core more but the mem is great!



GOOD JOB. The core is currentl the bottleneck

I would say 80-90.

Get the 88

If you keep on waiting all you will do is wait and wait....

Yeah, your clocks are pretty nice.

Why stop? If you can keep overclocking..do it! What will give you a noticable improvement now will be if you can get your vcore up higher.

As for temps..I would never run at 100C.
Hell, 70C is stretching it..that should be your max.

The hotter your card is, the more artifacts you will see. It'd probably be a worthy investment to get a third party Zalman cooler for the card.

Yeah, go with the 88 series. A GTX is pretty spendy, a GTS is the best bang for the buck.

ok thanks for that.... i was running the racing game test drive unlimited for about 15 minutes and found the temps got up to 80 degrees....

i have a LCS armor so i am able to get a vga block and watercool the Graphics card... i think that would be the way to go

as for the GTS is it worth getting the 640 or just get the 320

also i am running a 22" Samsung 226BW which i got on the weekend which is fantastic but my question is that i am also running a 19" benq as dual monitors... will this affect my performance whilst in games or will it be fine???

thanks a lot

The 640 is worth extra money

ok thanks for the advice... im running at 1680x1080 on my samsung so i guess the 640 is for me...

still need to know if the dual monitor is affecting my performance but i cant see

also would you advise me not too upgrade to vista until i buy the 88 or will it be fine on the 7800 in the meantime

what speed on the core would you say i should go up to for the 78gt

DON'T GET VISTA UNTIL YU HAE TOO

Big framerate impact. With the gts dual monitor will not really affesct it but on my card it does......ALOT. The core speed is all trial and error. I am not sure.

WHat kind of video card cooling do you have?

A little bit.

You NEED extra cooling for a better overclock. Thats GREAT for stock cooling.
