OC Report: Chaintech Apogee GT PC8500 2x2 GB

[Xtreme Addict]

It's high time to start a new topic here Because of holidays don't think that I stopped testing ram all day all night

This time I checked not so popular manufacture - Walton Chaintech (maybe you remember motherboards, graphic cards etc. ?). He changed directory and moved to RAM market.

About Apogee GT PC8500 2x2 GB:

Specification:
PC8500 (1066 MHz DDR)
2.1v 5-5-5-1 (TRFC52 from SPD)
6-layer PCB
Radiators almost like Dominators

Some photos:




























Sorry for bad quality of pictures but I set bad settings via Irfan View and it overwrote original files and I don't have this set at home now to do new pictures...


Here is a photo of ICS (a bit obscure )

(BTW, how to do thumbnails?)

It's Promos stuff (I think so ).


Testing configuration:

Gigabyte X48 DQ6
C2D E6400
Pentagram 1050W
Seagate 7200.10 320 GB SATAII
HD2900 PRO Sapphire
Cooled by L/C
Windows Vista


And... TWO pairs of Apogee GT PC8500 2x2 GB, 4x2 GB run also!

Results:



First pair of Apogee PC8500 GT 2x2 GB / 2.3v



Second pair / 2.2v



Two pairs connected totally 4x2 GB = 8GB / 2.3v

They are based on Promos ICS. Very nice memory, they scales up to 2.3v.

Conclusions:

Those Apogee GT are amazing pieces of RAM They overclock really nicely and fly on every motherboard which I own Radiators are good (the same as in Corsair RAMs), they are good looking and are elegant. Red label with Apogee fits those black aluminium radiators

Very nice, as usual!

Still amazed they aren't PSC...looks like we have some new contenders in the high end 2x2 GB DDR2 arena.

How difficult is it to remove the heat spreaders off one? Most importantly once removed can they be reassembled back onto dimms? If they don't break while removing I'll check the IC part number on my 1GB sticks. 1GB's have done 1200MHz for me, not sure if I can push them any harder haven't exactly tried.

Edit: Oops nevermind I see how the heat sink comes apart now I'll pull mine off next time I open case up and take some photos.

Sorry but I have to disagree here with you.

The heatspreaders may look like our Corsair DHX Spreaders (nice try of plagiarism I would say) but that´s about all they have in common.
Theres no DHX concept - no nothing - just some standrad heatspreaders with some larger fins on top - that´s it.

Also: If you look carefully you can see on the pictures that the spreaders on the top of the module are closed - where shoud the heat go? Right - it will stay inside and heat-up the modules (to be more precisely the PCB and the chips) more and more...

To get more information about our DHX please visit: http://www.corsair.com/_appnotes/AN6...y_Overview.pdf


And please: Next time do not compare apples and oranges

You are right Human is learning all the life

I have never had Corsair rams in my hand (and I couldn't pull of heatspreaders) but on the first look those Apogee are similar and you have to admit it But after studying PDF of DHX technology from what I see the most important is PCB which allows to transport heat And in addition Apogee's heatspreader end is built up so there is no hot air circulation.

how on earth did you run them on perf lvl 6? is the reading correct?
did you test lowering the tRP? what i like about PSC is 5-5-3-x ...

On a good mobo, 380 FSB + tRD 6 isn't impossible.

I just went and bought 8gb of the 9200 rated models. I'm hoping to get some nice clocks out of these, paid the same price as I did for a 4gb kit of dominator GTs which only reached 1120MHz. Thanks for posting the mini-review

thx for sharing, and the images are good qualitiy

These arrived earlier last weekend, one of the sticks was dead so I've arranged an RMA for a pair. One kit seems to hold up nicely at 1153 on only 1.87v with their standard timings. Here's results from overnight prime blend testing:



I think at voltages higher than 2.0 temperatures do seem to become a bit of an issue, so a fan or at least some good airflow would be advised if anyone tries it. I might be tempted to replace the thermal paste uder the sinks if they come off easily enough. Has anyone else tried it?
So far I've pushed to 1168 which was memtest stable, but not certain about prime. As long as they do what they say on the box I'm happy, and at half the price of some lower rated sticks these are a bargain, apparently there's loads left too, but not sure what the chances of getting another duff stick are
