3GB slower then 2GB?

post #1 of 10
Thread Starter 
OCZ Platinum 2GB (2 x 1GB) DDR 400 Default times - 2-3-2-5
http://www.newegg.com/Product/Produc...82E16820227210

OCZ Preformace 1GB (2x512meg) DDR 400 Default times - 2.5-3-3-7
http://www.ocztechnology.com/product...al_channel-eol

I was playing around with system to see if it could worked so i only put in the 2GB. Well the comp worked, installed vista and stuff, and i did the quick Windows preformace thing on vista, it gave my RAM a 5.0 rating. Well, i turned off machine mounted everything added the other 1gig or ram and booted it up, and now its tellin me that its 4.6 rating.

So with the extra gig its slowing it down? Perhaps the timing on the 2gig were really good, and when i attacked the 1 gig, it knocked it down a bunch. I cant see why it would make it even worse tho... Gona start DLing 3DMark to test out the ram and stuff and see which one clocks better and run it tonight.

Any suggestions or Ideas why its doing this.

Windows System Rating probably isnt too credible, but still makes me wonder.

notice how the timings on the 2 x 512 are slower, so ya its slowing down your system cyz in computers youre only as fast as youre weakest link, the better RAM is getting throttled to the slower times

Vista performance index is useless.

Use a memory benchmark like SANDRA or Everest.


For Vista, I would go with slower 3GB than faster 2GB.

WOW... kinda shocked to hear that... Yeah, i figured the timings would hold it back some but MAN... make it slower?? Well ill run those tests later tonight and post the results, i wana know how much of a diff it makes...

Also, i get to OC with 2gig =)

With 4 sticks you also default to a T2 timing command on a 939 system.

Vista bases that score on bandwidth, so OC your RAM if you want something higher.

GHz (gigahertz, billions of cycles) is a measure of frequency/speed.

You are refering to space/amount which would be GB (gigabyte, technically a billion bytes), or GiB (gibibytes 1024 bytes cubed) if you want to get fussy.

On your setup, four sticks of ram will force the memory control to use a T2 command rate, which is a fairly large hit in memory performance. This, combined with slower timings, explains your lower memory score.

Still, as soem have said, more, but slower memory, may be more useful than less, faster memory, atleast if you are using lots of ram.

I dont think any of my games will need more then 2 GB . I downloaded Everest 2.2 home edition... is that one ok? even though its like 3 years old. Also downloaded Sandra.

Lately i have been playing WoW, Crysis, and Hellgate London.

Again... you are using Vista..... use 3GB.

1T vs 2T = <5% performance.
2.5-3-3-7 vs 2-3-2-5 = <2% performance.

3GB vs 2GB = you'll notice it.

agreed. i would also do this with XP, XP can use alot of RAM too, if your gaming, and 3gb of a slower speed will be faster than the 2gb
