[font=Times New Roman][size=7]Hello all. New to BC. Seems to be a very useful resource. I'm hoping that those of you who are regulars will be able to reply to this message and help me with a problem.

I have an older PC. A AMD Athlon, model 4, 1.0Ghz. cpu loaded with the original BIOS. I recently bought a new game, DDO, and cannot play it on my system. I get an error message that says: "SSE is required but is not present. Check your motherboard documentation to see if SSE can be anabled." I have done lots of research, have updated the BIOS from Compaq, (it's a Compaq machine), and spent endless hours searching the internet. I need to know definitively if my cpu will support SSE, not just MMX and 3DNow!.

Please send me a reply if you can help at all.

Many thanks in advance. :thumbsup:

I did a google search with the information you provided, and found this quote.

The next revision of the Athlon was basically a .18-micron version of the old one (Orion core, AKA "A Athlon", AKA "K75"). It ran from 500MHz all the way to 1GHz, and like the Pluto it had a 100MHz front side bus and didn't support the SSE instruction set. All of them had 512KB of L2 cache that didn't run at full speed, but the speed varied from model to model; the L2 cache on 500~700MHz Orions ran at 1/2 speed, 750~850MHz Orions' L2 cache ran at 2/5 speed (eww), and 900MHz~1GHz Orions' L2 cache ran at 1/3 speed (ewwww). All of them were Slot A too, I think.

Please see this link, for the entire contents of the post. To find it in it's entirety, scroll down to the third post by SDA posted on Apr 11 2004, 06:47 AM. The quote is the 7th paragrah within in that post.
