Memory madness

Be careful that crashes on the PPC side are possible with those HP simms if your PPC busclock is 60Mhz and 603e is clocked at 240Mhz. It seems that that's the breaking point for those HP 128MB simms.

That's just bizzare :-/ Exact same SIMMs were used in plenty of 66MHz FSB PC systems AFAIK.

It seems a few people have experienced problems with these SIMMs dying after some time when runnign at 60MHz on BlizzardPPC cards. The 240MHz version uses a 60MHz FSB (the 50MHz is the 680x0).

It's strange because a lot of these large capacity SIMMs were designed at a time when 60/66/75 MHz FSB speeds were quite common for PCs that used them :-?

It doesn't hurt to test it out. Here's how to do it.
Install full 256MB of ram on your 240Mhz PPC card and run Gears_PPC and let it run for 30+ minutes.

I would usually get a crash with anything PPC related (like a game for example) within 5-10 minutes.

p.s. I'm not trying to sound doommasterish here regarding these simms. It's just the way it is. :-) Ask haymiggan for more details. :-)

How odd. I played GLQuake for a good hour on mine, no problems. I wonder what the hell gives?
