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!
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.
The board dead after about 10 or 11 monthes
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。
Good product works well Fast delivery
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
Box was well aged but was exactly what I needed new old stock
