    Good Motherboard

    Can not beat the price and functionality of this motherboard. It may not over some of the other features as more expensive boards. but what it does give you cannot go wrong in buying it.

    ASUS?

    I've been with ASUS since 2005/2006 exclusively I can't get an ASUS board to boot just into BIOS/UEFI forget about trying to put an OS on a M.2 SSD I'm looking at you ASUS ugly! This ASROCK board was a last resort out of frustration and it worked perfectly 4 stars why? because you sent me a used board saying it was new but the price was right... RGB?<- I don't need a Christmas tree MB or a lit up case I need a fast gaming rig not a Christmas tree, RGB can go away!

    No IO Shield in the Box

    Product seems to work fine. Documentation is terrible. The box did not have an IO shield. I don't want to return it. I just want someone to ship me an IO shield. I'll upgrade the review if someone can do that.

    通常運用なら問題なし。

    M社製のX299マザーが不調すぎて買い替えました。載せ替えて数ヶ月立ちますが、今の所特に不具合等は起きていないです。強いて挙げるなら、フルスクリーンロゴを使用しないとなんとも味気ないというか・・・デバッグコードが小さすぎて読み取るのが少し大変。LEDセグメントとして基盤実装してほしかったかも。まあこの辺は蛇足です。(特に不具合でなければ読み取ることもないし)あと公式には記載ありませんが、メモリCrucial BLE8G4D26AFEA.16FBD←動作確認とれているのは16FADで動作確認済みです。

    Spartana ma completa

    Molto minimal però con un sistema dissipante per le vrm semplicemente impressionante...! Funzioni rgb al minimo, ma ha 2 header x altrettante estensioni, strisce o ventole, queste sono indipendenti e la cosa è molto interessante. Devo dire che solo la Strix offre qualcosa di meglio, la tomahawk è anche peggio, il suo software nemmeno funziona come dovrebbe ( spero che sia solo un problema di patch e non di scheda madre o componenti hardware )Bundle essenziale, due cavi sata, cd, manuale, vitine per gli m 2.0 con sorpresa delle sorprese un ponte rigido high bandwidth per lo sli-cross fire, davv
