A8R-MVP Quirks

[MadMatty]

Ive recently got a cheap A8R-MVP to replace my dead Asrock 939DS2. On the whole I quite like it as I can push things a little more then before.

One annoyace is that on a cold boot it doesnt seem to acknowledge the fsb speed setting so just boots at "multi x mem divider". Cant figure any way round this atm. so i have to enter bios and hit save just to get settings I want. Using bios 0603

Bit annoyed that max cpu clock appears to be 2660 which is only 60 faster then what the asrock gave me. Max voltage is same as asrock (1.350v) but shows as around 1.390 in monitor and with overvolt hits 1.40-1.41. dropping ht multi and mem divider doesnt help push further :/ oh well. Ill just add that the cpu default is 1.30v

GFX clock on the other hand I am able to max out the overdrive gpu speed at 885 stable and mem 1275. Asrock i could only do 800/1175, anyhigher and the card would black out. makes me wonder if the asrock simply has a weak pcie voltage.

It is mainly the not booting at the correct oc thats bothering me, although if I do a keyboard reset just after post, that sorts it and it loads my settings. Just the fsb speed its not acknowledging at boot. Interestingly if i use case reset button for what ever reason such as a bsod or gpu freeze (got these testing oc settings) it woulf forget that value again, and require a keyboard reset to load it again.

Apart from that im getting a tiny bit more out of the cpu and a fair bit more out of the gfx over the dead asrock i was using before so I am happy. Just wondering if it is a common fault with this board or ..just me

thx for looking into this.

Im using the latest 0603 bios. I think ive hit the 260 issue already where ive had to drop to cmd rate of 2t to be stable. the cpu default is 1.30v so i guess its setting +.05 as max selectable for me.
