Whakaaturanga
Hengstar Converffered DDR4 DDR4 SDRAM SMIMMS (kaore i te kaha te whakakore i nga waahanga mahara-tau takirua, nga tauira mahara tere-tere e whakamahi ana i nga taputapu DDR4. NS08gu4e8 he 1G x 64-bit kotahi rarangi 8GB DDR4-26666 CL19 1.2v sdram insberfered dimm Fimm, e waru nga waahanga FBGA. Kua whakaritea te SPD ki a Jedec Latecy Latency DDR4-2666 Timing o te 19-19-19 i 1.2v. Ia 288-pin dimm te whakamahi i nga maihao whakapā koura. Ko te SDRAM kaore e kitea hei whakamahi ma te mahara ki te whakauru i roto i nga punaha penei i te PC me nga mahi mahi.

Panui:

1. Ko nga mea nui ake i te hunga kua raarangi i raro i te "whakatauranga teitei tino" ka raru pea te kino o te taputapu.

Koinei te whakatauranga o te ahotea anake me te mahi mahi o te taputapu i enei, i etahi atu tikanga ranei i runga ake i te hunga kua tohua ki nga waahanga whakahaere o tenei whakakitenga. Ko te whakaatu ki nga tikanga whakatauranga teitei mo nga waa roa ka pa ki te pono.

Ko te pāmahana o te 2.Storage te pāmahana o te take i te pokapū / runga taha o te dram. Mo nga tikanga whanganga, tirohia te paerewa jesd51-2.

3.VDD me VDDB me i roto i te 300mv o tetahi i nga wa katoa; me VREFCA kia kaua e nui ake i te 0.6 x vddq, i te wa iti iho i te 500mv; Ka rite pea te VREFCA ki te iti iho ranei i te 300mv.

Ko te 4.vPPP me rite te nui ake ranei i te VDD / VDDB i nga wa katoa.

5. Te rohe o te rohe i runga ake i te 1.5V kua tohua i te DDR4 taputapu .

Nga tuhinga:

1.Ko te Topter pāmahana pāmahana ko te pāmahana mata o te taha o te pokapū / runga o te dram. Mo nga tikanga whanganga, tena tirohia te tuhinga Jedec JesD51-2.

2. Ko te waahanga o te pāmahana noa e tohu ana i nga pāmahana e tautokohia ana nga whakaritenga DRAM katoa. I te wa e whakahaerehia ana, me pupuri tonu te pāmahana take dramam i waenga i te 0 - 85 ° C i raro i nga tikanga whakahaere katoa.

3.Ko nga tono tono me mahi i te DRAM i roto i te whānuitanga pāmahana i waenga i te 85 ° C me te pāmahana take. Ko nga taapiri katoa ka whakamanahia i roto i tenei waahanga, engari ko nga tikanga e whai ake nei e pa ana:

a). Me takirua nga whakahau whakahoutanga i te waa, na reira ko te whakaiti i te aukati i te wahanga o te waa ki te 3.9 μs. Ka taea ano hoki te tautuhi i tetahi waahanga me te 3x whakahou (Trefi ki te 7.8μs) i roto i te waahanga pāmahana whakawhānui. Tena koa tirohia te SMDM SPD mo te waatea.

b). Mena e hiahiatia ana te mahinga whaiaro-whakaora i roto i te waahanga pāmahana roa, ka whakahaua ki te whakamahi i te aratau-whakaora-a-ringa me te kaha o te waahanga pāmahana (MR2 A6 = 0b me te Mr2 A7 = 1b Aratau (Mr2 A6 = 1b me Mr2 A7 = 0b).
