Creme de la creme: TEAM Xtreem TXDD2048M1800HC5DC

[Micutzu]

TEAM Group announced a while back new models for the Xtreem series, that were meant to compelte the offering in both extreme performance (DDR1000 5-4-4 and DDR800 3-3-3) and good value overclocking (DDR533 3-3-3 Micron D9) segments.
Few days ago i got my hands on some of the new models and i couldn't wait to see what the highest-rated part could do. I'm talking about the M1800HC5DC, a memory kit that has double rating and comes in both 2X512MB and 2X1024MB flavours; i guess everybody's interested in what the 2GB kit can do (i know i was) so that's what you guys are going to see next.

First of all, here are the official specs:

Capacity: 2X1024MB
Rating 1: DDR1000 5-4-4-10 @ 2.2 - 2.35V
Rating 2: DDR800 3-4-3-8 @ 2.2 - 2.35V
Chips: Micron D9GMH



As you can see, there are some nice timings with some nice clocks, and the working voltage range is a little higher than usual DDR2 specs. This (and the fact that they beg you to overclock) means higher heat dissipation, but the heatspreaders are well designed and take care of the job pretty well. Don't think that if they look so slim and simple are there just for looks, the open-top design allows air to circulate betwen heatspreaders and PCB, practically almost doubling the radiant surface of the heatspreader, and more importantly alowing the PCB to cool better. I don't know how common this knowledge is, but the PCB is taking 70-80% of the heat generated by the chips trough the chip's pins/pads wich are metallic, and only a small part is going to the heatspreader trough the plastic casing.



At 2.5V you don't need extra ventilation to keep acceptable temps, and even at 3.01V (wich was the highest voltage i've tested) a simple medium rpm 92mm fan did the job very well.

This doesn't mean that 3V is OK for DDR2, it's actually beyond any limit of reliability, i've used it only for brief tests and i wouldn't recommend more than 2.5V for everyday use, and this only for Micron D9 chips. 3V WILL kill your DDR2.

I did the testing on the following setup:

Motherboard: Asus P5B-Deluxe, Vmch = 1.9V
CPU: Intel E6600
VGA: EVGA 7900GS @ 600/950
PSU: Tagan U15 580W

OS - Windows XP SP2 in diagnostic mode, VGA drivers - 91.47's tweaked for performance (including LOD), ~20C ambient temp, stock CPU cooler, 1.5V Vcore, one 1500rpm/92mm fan blowing on the RAM/NB area.

I chose 3 usual sets of timings and i chose the PSB : DDR ratio so as to get the highest RAM clocks on the Asus P5B-Deluxe. I used 3 different voltages in each case to show the extraordinary voltage scaling of the Micron D9 chips, and the tests ran were SPi 32M, the two Lobby tests from 3DM2001 and the Latency test from Everest 3.01. Benches ran in realtime mode.

For the beginning, a quick stability test at default RAM clocks, DDR800 3-4-3-8 and DDR1000 5-4-4-10 respectively, with a voltage from the working range, 2.3V. Higher Mhz + higher timings seem to be faster trough SPI 32M.

DDR860 3-3-3-8 2.2V




DDR920 3-3-3-8 2.4V




DDR990 3-3-3-8 2.75V

[Micutzu]

DDR 1050 4-4-3-8 2.2V




DDR1120 4-4-3-8 2.4V




DDR1212 4-4-3-8 2.75V



This brought up some problems of the mobo, 4:5 could not clock the RAM as high as 2:3 even if 500+Mhz on the PSB didn't seem to be a problem.

[Micutzu]

DDR1100 4-4-4-10 2.2V




DDR1180 4-4-4-10 2.4V




The 2.75V run was limited by the motherboard as i couldn't get 4-4-4-10 to clock higher than 4-4-3-8 at this voltage; i'm sure this RAM can do better in a more unrestricted setup.

This is it, i hope you enjoyed it

Thx test Micutzu and Congratz CL3 WR

I'm testing my new rams , Teamgroup 2GB 800C4, but max CL3-3-3-8 on 2,43v, 810Mhz. (Micron D9GMH) Little bit low.

mod: I use Asus P5W DH.

[AsAsIn8eR]

Congrats very good memory!

[filmbot]

Very good results Micutzu.
Can these be had at Tank Guys do you know?
Also, any reason as to why 2:3 will clock higher than 4:5?

[vudoodoodoo]

So much memory, so little money.
Wow, nice clocks w/ 3-3-3-8.

[Micutzu]

This stuff has been available from TEAM after the middle of this month, but it's pretty much limited edition and might not be available everywhere. It's 2 times more expensive than the DDR533 3-3-3 Micron D9 stuff wich they've also launched recently, but still cheaper than Corsair's or G.Skill's similar stuff.

[ozzimark]

i said this when i saw 430mhz at 2.2v with 3-3-3.. "holy crap."

nice sticks
care to give 5-5-4 a go?

[Gautam]

Awesome results! 495MHz 3-3-3 32M stable really is something.

[TaPaKaH]

put `em under 2.5V+ and go get some more
nice DDR2s m8

[K.J.]

Bonne mémoires vives

Vous pouvez venter moi la?

[Avman]

My Team 667 3-3-3-8 does DDR2-1008 4-4-4-11 24/7

They'll do DDR2-1100 5-5-5-13 orthos stable all at 2.25v.

C'est ne pas pour vendre

[erwinz]

nice rams.. :d team xtreme are producing the best rams over price ratio..

[GrimReaper]

wow amazing stuff where did you buy them from ?

[Micutzu]

Romanian reseller www.senorg.ro

[TeamUSOffice]

wow amazing stuff where did you buy them from ?

I am asking Taiwan to send some over here.
Anyhow, Micutzu is right about there won't be too many of this. I'll be guessing like 20 sets might be avalible @ www.tankguys.com in a week or so.

msrp, $600? ?

[ozzimark]

msrp, $600? ?

i'm gonna venture a touch over $400.. since that's what ram with similar ratings go for

[Zyklon5]

In Romania this kit goes for around 510$ 19% tax included http://www.senorg.ro/shop/TeamGroup-...C---p2055.html but then again the same kit that TankGuy sells for 277$ is 312$ in my country .. so there is a 12% diffrence .. my take is around 450$

Micutzu great performance show ... once again

[TeamUSOffice]

msrp, $600? ?

MSRP $440.00, As far as I know tankguys always sell lower than my MSRP.

[TankGuys]

It's now listed on our site, but won't be available until ~mid next week. Price is at MSRP this time - sorry guys The difference between my cost and MRSP on these is pretty small, so I didn't have any room to shoot low this time
