How long until they put the kind of ram on video cards, on to ram sticks. The new high end cards have like 1.4 Ns timings
latencies of video card memory are way too high
Look again at these modules!!!
The Speed Premiums tested have had a change in the ICs and now use Winbond UTT (UnTesTed) chips which are showing up all over the place. You can tell them appart from the sticks using the prior ICs not only by doing a visual, the new ones look like the bh-5/bh-6 of old, but also by the parts number on the stickers attached to the modules.
The ones tested in this review end in the coding AADT, the new ones use the coding ending in AA4T, (notice the D vs the 4). This code change is also printed on the ICs themselves, where the mfg. date is printed on the ICs, the old ones have the date (YYWW) plus the letter D, the new ones follow the Year/Week info with the number 4. An example of the old would be 0443D, like the modules used in this review and the new ones will look something like this...04514.
These new ICs, while showing no significant differences at default voltage, will scale through the roof when shot with extra voltage and perform very similar to the new line of extreme voltage memory from OCZ. In fact, there is much speculation that these same chips are used my OCZ to make their eXtreme Voltage series ram.
These sticks, with the new modules are hitting outrageous speeds of 255-275 at 2-2-2-x timings on both Intel and A64 systems. The only drawback is that you have got to be able to provide them with voltage in the 3.2v-3.6v range in order to get them to perform like this.
If you think these are not good overclockers....think again!
i know, i'm the guy who discovered it with help from (ALEX working for Twinmos Germany) there will be soon a review of twinmos/winbond UTT :>
But the tested ram are AADT
4=Winbond (doesn't really exist anymore, cauz Infineon now "own" winbond)
I=should Samsung or something like that
H=other brand .. hynix or so, don't know
I know that you know, because I post over at XS as well. It was the other readers that I was sharing that information with. And thanks for the tip on the other makes of ICs used in these modules. I wasn't aware that Samsung nor Hynix made blanks or will these carry the Samsung (or Hynix) labels on the chips?
Looking forward to your review of the Winbond (yes I know Infineon bought Winbond, but they are still Winbond chips to me). Let us know over at XS when you've finished.
