Is Corsair Dominator RAM actually faster?

post #1 of 14
Thread Starter 
So when I built my system about 2 weeks ago, I originally purchased this RAM. Installed it and it was awesome. Ran at the correct 8-8-8-24 timings right out of the box, as well as the 1600MHz speed. Windows WEI rated it at 7.7 out of 7.9

Then I got an awesome deal for some Dominator RAM (2x2gb) CL8 on eBay. Bought them ($33) and installed them into my system. I took the PNY out of my system so I could test the Dominators to make sure they worked (bought them used) and that there were no issues. I ran the WEI test again, and my RAM rating shot up to 7.9

I thought this was strange, because the timings were also set to 8-8-8-24 @ 1600MHz. Both RAM use the same voltage too.

I then took out the Dominator and put the PNY back in. I ran WEI one more time and my rating fell to 7.7

I know WEI is crap, but it has to show some truth to it. After I saw this I decided to buy 4gb more of the Dominator and gave the PNY to my friend. Is there any truth to this? I know Dominator is overpriced, but is there really a performance gain to it? Just wondering if anyone knows any truth to this.

No. WEI is definitely crap and can fluctuate for no reason. Memory performance is based solely on the frequency and timings, it has nothing to do with what brand it is. And Dominator memory is usually overpriced like you said, although $33 is a good deal. CAS 8 at 1600mhz is pretty average and nothing to get excited over.

Sub-timings.The RAM should perform the same at the same exact timings and speed,unless it is different architecture like DDR2 vs DDR3.

I thought it was WEI just being stupid. Just though it strange the the PNY rated 7.7 2 out of 2 times, while the Dominator rated 7.9 2 out of 2 times.

Oh well. At least it looks cooler :-P

Everything in my system is rated 7.9 except for my processor, lol. Rated at a lowly 7.7

Do you actually care what WEI thinks of your rig?

Screw WEI. What does it know?

@karmuhhhh

Different Command Rate? (could be that the Corsair defaults to Command Rate 1N and the PNY to 2N).

Different subtiming?

Different IC?
