White flecks: core or memory?

[Smiff]

Just a quicky : when I push my G400 over 152/203 I get white flecks across the screen. Would a fan help?

(Sorry if this has been answered before)

from what I understand.. it's memory. Someone suggested using thermal glue to attach heatsinks the the mem chips...

I don't recommend the fan solution. If three degrees down is the solution, it's definitely not a stable one. A much better way is to relax the memory timing parameters. I am going to describe this in detail on my website *soon*. My OEM G400 DH (6ns) works happily at 203/152. It didn't work with the default timing settings at this frequency.

Thanks guys. Having though about it, I realized I don't have any space for a fan anyway!

gbm: do you mean using MGAtweak's "SGRAM/SDRAM optimization"? Nice idea, i'll give it a go

fragtaping "chunks" of an old heatsink onto the memory helped me out a little along with a blo-hole pointed at the vid card, ram, and cpu

gbm: but wouldn´t the slow memory timings slow everything down? I mean, I can get past 153/204 if I slow down the memory timings in mgatweak, but it´s slower than 150/200 (that´s the speed it usually runs at).

[Smiff]

I found fiddling with memory timings made no noticeable difference to performance at all!

(that's using MGAtweak to fiddle and D3Dtest to test)

It did, on several attempts, cause my screen to fill up with coloured dots, which was quite pretty, but not exactly what I had in mind

I get white 'flecks' on all of my windows whenever i'm in DualHead mode... makes me wonder :|

Head and Shoulders would fix the problem maybe?

I'm sorry I couldn't resist

[PurpleHaze]

Dual Head and Shoulders?

I could have resisted, but I didn't.
