Overclockig my G400 16mb(6ns).

[Walrus Bonzo]

I have a 16mb G400, with 6ns memory and an added fan to help keep it cool..

I was wondering what the best settings are for clocking this amazing card..

What memory settings should I use??

I have already tried 144MHz Core and 180MHz Memory, which is fine for windows but some(Not All) Games crash randomly after a few mins.

Am I overclocking the Memory too much??

Thanks In Advance

My G400 16MB DH worked 150/200 for several hours before I restored defaults.
It was running Q3 1024*760 allthe time, and didn't crash.

I run my vanilla 16mb sgram 6ns at 174/217 without a fan and with a fan it goes to 180/225 with agp@75mhz for over 4 months now pumping all, from 3d stuio max3 to UT or Q3 and 3dmark2000. imagine this on a 0.18 core

Leporis, I think that has got to be a record!

leporis that can't be right..

With a fan mine crashes even at 138 core and 172.5 memory!!!

My Max won't even do 174/217!

[leporis]

i assure you guys that this is right because i notice a significant speed increase from the 150/200 to 180/225 and at this speed (i won´t even mention the speed increase from 126/168, oh! i already did!).
In 3dmark 2000 i get a fillrate of:
(all at 1024x768x16 z16bit)
228MP @ 126/168
265MP @ 150/200
335MP @ 180/225 (have to slow mem timings)
315MP @ 180/200

Oh, i forgot to mention that my g400 is pretty old. it´s from late August, Honest

leporis,

You've got an amazing overclocking result even on a vanilla!!!

Can you publish your mem settings?? I think you need to tune the memory before you can go that high.

that´s right kjliew, and here it goes:

leporis,

Are you using these other settings wiith your mem settings??:

pll 435Mhz
Gclk 2.5
Mclk2
Wclk2.5
Duty cycle 0,11,0

And are you sure that you have 6ns of mem??

If it is correct, it doesn't work on my G400 and I got my card in June '99.

[leporis]

yep Cyberdude i have 6ns mem. At least it´s what´s on the modules surface. As to the rest you´ve got it right
