Some benchmarks on 4x512 vs 2X1Gb (Mushkin XP4000)

[guillaume]

Since I did this for myself, I thought I'd share it for those who are interested
I switched recently from 2x512 Mushkin XP4000 Redline 2-2-2 to 4x512.
I ran some benchmarks to compare it with Mushkin Redline XP4000 2x1Gb (my numbers come from a review on cdrinfo.com).
Not a perfect comparison, as the CPU speed differ and I don't own the 2x1Gb therefore rely on a published test.
But I think I can safely say that if you already have 2x512 of good (mushkin is great) RAM, you don't necessarily have to sell it and buy a 2x1Gb. Buying an additional 2x512 of the same yields roughly the same performance, and the 2T drop in performance is not so dramatic.

Nice work guillaume
it would be nice to see a OcF member with the 1Gig Redlines post there results though, it seems like the OCers here have more Skillz then most reviewers.. ROFL

True! I'm sure Zebbo and the other Mushkin guys have some better numbers

why no Everest results for the 2 x 1GB set?

A few questions:

1) Your UCCC does 288Mhz??
2) What speed is the 4x512 @?
3) Are you using same CPU speed for comparo?

Couldn't find benchmark on Everest - remeber I don't own the 2x1gb

1) Your UCCC does 288Mhz??
2) What speed is the 4x512 @?
3) Are you using same CPU speed for comparo?

1 - According to the review, looks like it:http://www.cdrinfo.com/Sections/Reviews/Specific.aspx?ArticleId=15912&PageId=0
2 - It's in my sig: 255Mhz
3 - Their system is a 3800+ @ 2.4, I have a 4000+ @ 2.8

Thanks for this review. I read it with interest.
A bigger issue for me, however, is the voltage difference.

The 4x512 run at 3.3-3.5 v while the 2x1024 run at 2.6-2.9 v
The cold boot problem with my mobo means I would prefer to sell my 2x512 when I upgrade to 2 GB.
