2x4 GB Corsair Vengeance with 2x4GB ADATA

post #1 of 8
Thread Starter 
Hi there,

any suggestions for this setup??

I already have 2x4 GB Corsair Vengeance 9-9-9-24 1600MHz 1.5V kit, and have cheap offer for another kit with same specs - 2x4GB ADATA 1600MHz 9-9-9-24 1.5V XPG Gaming Series 2.0.

its running in ASUS M5a97 EVO R2.0 MoBo at specified timing, at 1600MHz, no overclock.

Is this alright to get different brand to second dual channel slots??? what experiences u have with ADATA brand??

Thanks for any help.

Ah! Mixed memory.
Sometimes it works, usually it doesn't. Often you have to down clock the memory to make it work.
You're only looking at the "Published" specs. There are 31 timing options for memory, most unpublished.
Other things matter too. Double sided or single sided?

Thanks for reply, but found similar memory kit for cheap (2x4 GB Corsair Vengeance 9-9-9-24 1600MHz 1.5V kit) so do you think that should work definitely??
Only difference is in coollers probably (low profile CML8GX3M2A1600C9 vs CMZ8GX3M2A1600C9 regular), electrically looks the same, guy at corsair forums solved same issue.

What do u think?? Will it work??

There are only three ways to tell if they will definitely work together:
Try them together
Remove the heat spreaders and read the part numbers on the ICs (integrated circuit chips) and PCB (PC Board, the "Brain") and see if they are identical both in part number and quantity.
Buy memory in "Matched" sets.(ie all the memory in one retail package and that package identified as a "set".

Even the exact same two retail packages of memory, bought from the same store, from the same shelf, on the same day from the same salesman may not be a match.

Memory manufacturers often change the ICs (the black squares on the sticks) and PCBs (another integrated circuit chip) they use seemingly randomly, as these parts are basically "articles of commerce" and as such are bought based on Specs, availability and price. What corsair (or any other manufacturer) used on Tuesday to make a certain specification (ie part number) memory may be different for the exact same part number memory made on the next day. While the "Published " specs may be the same for both, the "Unpublished" specs likely will be different, and Tuesday's memory may not "Match" Wednesday's memory. Some manufacturers will denote the change on the retail package by adding a Rev, Number (revision number) to the part number, some don't, but alas, often the packaging will not allow the customer to see that number.. Corsair does a pretty good job on they website (ie Foum) identifying which ICs are used with which Rev. Nos.

Hope that helps...

HUH pretty complicated. better will try and if it wont work will send them back or sell forward..
dont understand very what could go wrong, if they are in another pair of slots and are tested to run at the same specs as first pair. (and we are talking of factory timings, not OC, which is useless when talking of memories - imo waste of time and tiny increase in final performance).

will let you know then, thanks

edit: great guide, http://forum.corsair.com/forums/attachment.php?attachmentid=6937&d=1275030443/

Here;s a list of memory "timings" that have to be the same in all the sticks for them to be a "Matched" set.

mem arived, sticker says the same Version (2.12) as previous kit, just different heatsinks, bios set the same settings as with one pair(1600, 9-9-9-24), manually set CR to 1T, boot with no problems, memtest86+ - 0errors, WMD -0errors, hopefully there wont be any problems in future.

theres slight improvement in performance, mostly seen in new games (like nfs rivals) there are shorter loading times,

lets see if corel will take all of 16gigs biggrin.gif
