List of chips used on DDR2 RAM modules

[Millyons]

ya lol thats right, damn disleksia

[mach82]

for anyone that is interested in value ram the PCS chips arent bad at all, my 1gb x 2 do about (dual windows memtest) 475mhz 4-4-4-12 with 2.4v and i tested up to 550ish with same voltage and 5-5-5-15......24/7 i run them at 400 4-4-4-12 2v they could probably do 3-4-4-12 at same voltage i just never bothered to test, i also never really tested their max, or their optimal settings......

I have Twinmos twister DDR800 sticks which are based on PCS chips as well. Stably DDR830 1.8V CL4 and more after adding more volts. DDR1000 CL4 2.3V and much more with CL5. Never tried more than 2.3V.

That stuff should be a pretty good deal considering the price and what IC the list says it has

[Kabauterman]

Nice List, very good

but Mushkins XP2-6400 CL4-4-3-X have D9GMH ICs ...


EM2-6400 CL5-5-5-12


AENEON

XP2-6400 CL4-4-3-10


D9GMH

XP2-8000 REDLINE CL4-5-4-11


D9GMH

XP2-8000 Redline is already on the list. Added the rest. Thanks for including pictures.

man can you put up somwhere pictures of the various chips, that would be awsome

it would help alot when indentifying relabeled ics

something like this used to be for ddr

I'll see what I can do. Got a busy week coming up, but I'll let you all know in this thread.

Corsair CM2X512-5400C4 v4.4 (LOT 0615117-2) is Elpida 6E.

[chema]

anyone knows which brand are these chips? someone told me they were micron.

thanks

[Millyons]

they look like elpida to me

That is indeed a relabled Elpida IC.

[Makubex_GB]

Great work roon. Keep that list updated.

Stilt... keep him updated.

Thanks. I have decided to stop adding Corsair modules because as we all know a huge list already exists on the House of Help Support forums.
RAM GUY is doing a great job over there so from now on I'll leave Corsair modules to him.

Merging the thread with my RAM List would make it three times as long and therefore less user-friendly. This is obviously not going to happen.

[chema]

That is indeed a relabled Elpida IC.

but I had another set of kingston with elpida, and they were not relabeled.
thes IC´s are totally square.
have yo known it by the numbers i wrote??

[Millyons]

from the small dots in the other two corners

ok,, thanks millyons

any news about these corsair TWIN2 2048-6400C4 Rev 2.1 cas 4-4-4-12

[.devastatioN]

Anyone would know these chips on

Part1 # CM2x512-5400C4
Revision # XMS5402v7.2
Lot # 0633070-2

It's corsair 5400c4 twinx 1gb kit, memory, but a new rev.
Rev 5.2 is Micron D9DQW, according to
http://ramlist.ath.cx/ddr2/

But I have v7.2, I already requested on HouseOfHelp but he doesn't respond.
http://www.houseofhelp.com/v2/showthread.php?t=44365

I haven't token of the heatspreaders but on the sides I can see it are 10x10MM chips, any idea since v7.1 is Promos and v5.7 are also Micronchips...

Quick question to the experts. Whats a better kit? Corsair XMS2 5400UL 1.2 or Corsair XMS2 8000UL1.1? And which IC's are better? Micron D9DQT (BT-3) or Micron D9DQW (BT-37E)? I have 8000UL's but I've found some new 5400UL's.

I'm not an expert but I may be able to somewhat answer that question, or at least share my understanding on them.

Comparing D9DQT and D9DQW is analogous to comparing DDR1's BH-5 and BH-6 or today's D9DKX and D9DMH, respectively.

The DQT was binned to higher speeds than the DQW, which was used almost exclusively in DDR2-PC4200 up to PC-5600 rated ram (and capable of 3-2-2-8 timings in models such as the Musking PC4200 and the Patriot PC5300 version, when running PC-4200 speeds). At lower clocks, both D9 fatbodies are capable of the same tight timings, however one has more headroom than the other.

The DQT, on the other hand, was usually found its way to DDR2-PC5400 and higher speed rated modules and would be considered by most to be the better choice for high clocks with as tight timings as possible. Hitting over DDR1000 speeds with DQT is not uncommon, however, topping DDR1000, while perhaps not impossible, is not nearly as likely with DQW based modules.

With respect to the question about which Corsair model is better, the 5400ULs or the 8000ULs, that is probably a "luck of the draw" thing, as both have shown to be very good.

Hope that helps.

Thanks alot, I think I'll buy the 5400UL's and see what happens. They are brand new & only $160 for a 1 Gig kit. I've tested my 8000UL's @502mhz 4-3-2-4 2.55v . They had 8 errors on a 12hour pass of memtest #5.

Before you buy them for $160 per gig, go to NEWEGG for $129 per gig... I got 2 kits and there are like 30 left.

[Reefa_Madness]

One less now.

I've got a 2x512 set of the 8000ULs and will try to run them together with these 5400s. I wonder if there would be any merit or harm to flashing one of the sets with the SPD of the other (after making a backup, of course) in order to have matching SDP info in the two sets? And if so, which set of timings would be the best choice? I'm guessing the one with the most forgiving timings to improve overall compatibility. I would think that flashing the 5400ULs with the SPD of the 8000ULs would make the most sense.

How can you do that? Do you have a special device or software?
