Well currently in my maching (should see in my sig.) has 2gb of patriot ddr2 800 RAM with CAS 4 timings 4-4-4-12...just running stock as of now. I want to add 4 more GB of RAM for a total of 6GB, but I'm trying to decide what ram I want. My budget is at most spending 100 bucks, but i'm not sure i wanna spend that much. I was looking at 2 different patriot rams, one is cas 5 with 5-5-5-12 and one was cas 4 with 4-4-4-12....the first set is only like 70 bucks, the second about 95 bucks...would the first set, the cas 5, slow down my other 2gb of ram, or be slow in general since they only have a cas of 5 instead of the faster cas 4?

also if anyone has suggestions of good ram, much appreciated....i was also looking at some ocz reapers for about 100 bucks but these are 4-4-4-15...any big difference?

also if someone could briefly explain how to change timing settings and ram voltage in bios..that'd be superb!

thanks
Zac

I missed the part about what OS you are running, 32 bit won't even see the full 4 gigs, even with vista 64 bit, 4 gigs of matched ram should be more than enough

dachew always saves the day for me!....

i'm running xp corporate..shh don't tell :-D...idk if it's 32 or 64 bit, beats me...but i guess if there isn't much improved ment between 2gb and 4gb then i'll just get 2gb (2x1gb) since price/gb its a lot cheaper than getting 2 sticks of 2gb

Thanks again!

you have the 32 bit x86?, if you had 64 bit you would know as it's such a hassle to find drivers

don't expect to see more than 3.25 gigs TOTAL with it, try to get the exact same sticks you have now

well i checked in msinfo32 and i guess it's xp professional s.p. 2(maybe that's what all corp. versions are idk) but i suppose it won't say 32 or 64 bit cuz i don't see it...

i haven't had any major driver problems tho so it's probably 32 bit

It may say it in msinfo - but I don't know for sure.
Go to Start...Run...and type in "sysdm.cpl" (without the quotes) and press Enter.
If it doesn't say 64 bit there - then you've got 32 bit.

I am using Patriot Memory now you should be able to Lower the CAS to 3 on your CAS 4 memory. You will need to bump up the voltage a notch but it should run ok. My runs fine even with my OC'd FSB. It may be different with your exact memeory. Make sure you know where the cmos reset jumper is incase the computer doesnt post. If it fails post just reset the bios and start over.
