Video Card Ram Questions

[SidewinderX]

Hey guys, got a few questions of the memory on a video card. (Mods, if this should be in memory, move it there please)

Anyway, I have Shappire 9600 Pro Atlantis 128MB, and I have it set at a fairly conservative overclock, 452Mhz/303(606)Mhz. I've been meaning to push it more, and I know I cna get more core upto 513Mhz fine, but the memory hardlocks if I go much higher than it is now.

I decided to investigate what might be the issue, so I researched what the memory chips are, and found that they are:
EtronTech EM6A9320B1-2.8 H100409MEH30014

So I went to Etron's site (http://www.etron.com) to look them up, and I found them. And I found that the chips are rated to 350MHz (700).

So my question is: why they heck won't they even get close? Can I do some BIOS flashing to get them more capable (like flash it to looser timings?), or will throwing heatsinks on there help?

Thanks!

(BTW, here is the Etron PDF with the info on them.... Here

Heatsinks would help alot. Probably might be able to push alittle more out of them.

I think the way they do it is based on speed. For example, if etron was producing 350 rated ram chips, some wouldnt do 350, they they stick them on a card that wont do 350 stock.

generally they make products that fit thier specifications... And, afaik, Shappire does a decent job of selecting thier chips... I'm hoping that it's just a bios flash / ramskins or soemthing...

anyone else know anyhting that might help?

Saphire may be undervolting them, because the would not need as much voltage to run at a slower speed.
