Windows Vista Performance Rating (RAM)

[Piesang]

I had 2 x 1GB DDR2 667 (Corsair) installed in my machine and the rating was 5.6

Today I added 2 x 1GB DDR2 667 (Hynix) modules now the rating shows 5.5

Why is that?

Piesang; Do not take the WVPR seriously.
It's stupid.

Probably the temperature outside.

 

[killadoob]

could be that the corsair has moved onto the slower hynix memory
corsair is superior ram

 

[xrapidx]

Oh wait... You ADDED memory... I thought you swapped.

WOW! a whole 0.1 Less!

yea WVPR = Fail!

With 2GB more, i.e. 4GB... you'd expect it to be moving the other direction, not?

Perhaps the Ram is running slower due to different timing?

 

[jmak]

You didn't specify the CAS values for the different modules in your post....?

i dont wrk with this vista standard,use other benchmark tools

 

[Praeses]

Vista doesn't rate on the amount of memory I think. Probably on ram speed so ram timings will influence the benchmark

 

[Glordit]

CPUz try that wil show you RAM make/CAS/Speed and all the rest

 

[ID10T]

lol... its windows, what did you expect

 

[Brawler]

Check the timings.
Highly doubt the hynix will be the same as the corsair

 

[Thestealth]

Definitely sounds like differences in latency/timings here. I suspect the hynix is choking your system.

You shud get a higher rating IMO. Even tho the Hynix speed is a little slower. More ram = better performance, that's obvious.

I know my 800MHz Mushkin 2x1GB @ 5-5-5-12 gets 5.9...667 with 5-5-5-?15? timings would probably get 5.5ish.

Using all 4 slots on the mobo probably forced T2 command rate? Using 4 slots is known to cut down bandwidth slightly. It could also be CL4 vs CL5 RAM timings, check all that with CPU-z.

The Vista rating (and any other memory bandwidth benchamrks) will rate the RAM slightly slower because it is. There is of course more of it, and that will probably make a bigger difference if you ever use it all.

Still I think that Vista Performance thingy is broken
