Windows 7: CPU-Z pics: A-Data vs Corsair mem in my rig: pls advise

CPU-Z pics: A-Data vs Corsair mem in my rig: pls advise

When I bought my rig, the builder had put the wrong memory in it. They read the build sheet as "Corsair or Major Brand" and "upgraded" me to A-Data Gaming Series. The thing is, I had ordered Corsair Dominator. They were OOS of the Dom when I picked it up, so they offered to refund the upgrade fee and keep the A-Data, or ship the Dom to me when it was restocked. I went with the latter and have been running off the A-Data for over a month. I received the Dom a few weeks ago, but did not have the chance to pop it into my rig until today. I ran CPU-Z and now I am wondering if the Dom specs are truly better that the A-Data or not (I am not that well-versed in memory ratings and such). I think I would still have the option of shipping the Dom back and keeping the A-Data, but I want to keep whatever is best. Please advise.

A-Data SPD tab


Corsair Dominator SPD tab


A-Data Mem tab


Corsair Dominator Mem tab


From the Mem tabs, the Dom looks better than the A-Data, but to me the SPD tabs make it look as if the A-Data is better than the Dom. Maybe I am just reading this wrong. I dunno. I be . Any explanations will be greatly appreciated. TIA!

BTW, if there is a better util to run to rate my mem, please let me know and I can do that. It will not be a problem to pop the A-Data back in and get a reading.

You should check whenever the A-Data are especially made for the i7 processor series...on the manufacturer site or your retailler.
Looks some of DDR3 PC3-10700 are made for this i7, and are generaly mentionned.

I think the Corsair are good but not the new generation for your " i7 860 @ 2.80GHZ "

Thanks for the reply. I guess I am a little green on this memory stuff, but I am not quite sure what you are getting at. How does "being made for the i7" actually work? I can understand some memory is better than others, but how can one be better for one type of processor and another better for a different one? Would the better one be better all around???

Anyway, as far as it goes, WYSIW I Can Get... I have no ability to specify what I want the builder to give me (other than A-Data Gaming or Corsair Dominator). Given that, would the A-Data be better since they are the PC3-10700, or are the Corsair Doms better because of the lower CAS, even though they are only PC3-8500F?

Thanks again!

I'm a little green as you on this either...but i was hoping an answer for myself on another thread and it came to me looking at your thread, i went to a retailler site to check what's up with PC3-8500F Ram for desktop (as mine actually, but on laptop) and PC3-10700 for desktop.

They did mentionned that those ram sticks (PC3-10700) were the newest made for the i7 Core series. If they're made for that processor it could mean they do suit perfect to your machine.
But as always makers are very annoying when popping up a new stuff, advertizing it is the best and sometimes older generation stuff works fine!

That's why i'm telling you to see whenever they do suit your processor. In that case it will be perhaps a clue for you when asking to the retailler, him to be more precise.

I doubt youll see much diff. between higher bandwidth/looser timings and lower bandwith with tighter timings in a real world situation.
Maybe in a benchmark.

To get a better idea of the performance difference you could run a benchmark and see what kind of bandwidth you have on each.

Windows has a built in one.

Open a elevated command prompt and type:

winsat mem

Wishmaster, thanks for the reply. If understand correctly, the A-Data is the one with the higher bandwidth/looser timings and the Dom has lower bandwidth/tighter timings, right?

Thanks for the heads-up on winsat mem. I ran it with on the Dom (which is currently installed) and here is the result:


I don't have the time to swap the mem out right now and run it on the A-Data, but I will do that the first chance I get and post the results.

The A-Data is absolutely better. Not just because it's faster, but because it's designed specifically for your hardware, and is newer.

Peace

Rhammstein, thanks for the reply. While I haven't had the chance to swap out the memory to check the A-Data with winsat, I would like to know how you can tell the A-Data is faster. I understand what Wishmaster stated above, and thanks makes sense which is why I am going to look into it, but I just want to know how you are reading the stats I posted above. Thanks!

Well, simply the A-Date will move more data per second, however, it does have a higher latency, however latency is far less an issue, than data/sec. With these numbers, the A-Data will move more data, so long as your mobo recognizes it and it's clocked accordingly, which it should. The memory is specifically designed for that Intel chipset.

I hope that answers your question, if you want more technical explanations, ask away.

Very simply, PC8500 equates to 8,500mb/sec, however the chipset has an influence as well. The exact numbers will differ always, depending on other components, which is "exactly" why they tell you what the memory is rated for, because memory will not always perform exactly as said, bottlenecks often exist, or the opposite, a great chipset and Cpu with heavy overclocking, for example. Take the PC3, 10700, this equates to 10,700mb/sec. I hope this helps.

Once you swap the memory and run the test, you'll see that the A-Data moves more data.

Peace

Edit: For example, on my main rig, not my gaming rig, the HP HPE-112y, this is how it scores, and it's only PC3 1066.

So, it can be very misleading. This good result is primarily because of the 4000mhz HT link.

Any other questions feel free, or PM. Peace, and no, I don't care about reputation points

Hmmm.....never heard of A-Data, but I can say Corsair's memory is VERY good.

At any rate, looking at CPU-Z, the dominators run at 1600MHz, were as the A-Data will only do 1370? I'd personally go with the Dominators as they are better sticks and will also clock higher.

One other thing, If your know how to enter the BIOS, set your Dominator RAM to XMP mode. Looking at this pic says there aren't running in full spec....




BTW I use Dominators myself. Here's mine....

In the first shot you can see my memory running at 1600MHz. In the second shot under part number notice the "1600". The only difference between your and mine is that I have tighter (better) timings. Yours is 9-9-9-24-2T, Mine is 8-8-8-24-1T, other than that we can both run at 1600MHz.

Hope this helps.
