Ram query

[Gorion]

hey guys,

i recently bought 2 1gig ram sticks with a 2.5cas latency, and i have another 1gig 2cas stick.  (i had two 2cas before but i replaced one with the 2.5)

now, since i installed those 2 my performance has totally degraded

(used to raid with full gfx from card settings and in-game for a minimum of 14fps, now everything is on minimum and ime getting down to 10 frames sometimes),

is it possible that different latency sticks dont work with each other?

[suicidal_monkey]

or that your motherboard cannot cope with three sticks of ram properly and is having to alter the timings? Have you tried with just the two new 2.5 cas sticks?

hmm nope havent tried that yet..

If your system can do dual channel joy you may find that taking the old stick out and putting the two cas 2.5 sticks int he correct slots for dual channel gives you better performance. I certainly don't have any problems running stuff at the moment at max graphical settings etc with only 2GB RAM, so I would have thought you don't need the extra gig.

YMMV, natch

hmm well i didnt need it.. i just wanted to have that extra gig just to be safe.. ille try removing the old one then..

bdw, nice pic of Mat3a

Thanks It's so long since I played the game i'd forgotten what she was called. Looked well fine on my old GeForce3, but when I got an ATI card it just all looked dull and bland somehow. Will have to try it sometime on my new nVIdia card. I seem to recall the reason for it was that it utilised something funky in nVidia cards that ATI didn't have to give a nice 'glow' to the environment, or something.

[Gorion]

maybe your old ati didnt have T&L..

ive got an ati.. and it looks immaculate

My old one was a 9800XT. I'm pretty sure it had more features than the ol' GeForce 3
