I bought recently a new mobo + proc.
There arent any good review for this mobo so i will try to do one.. maybe not as detailed as you would like but i will do my best:
First i had to flash it to 1.50 caus otherwiste it wouldnt be working with the core 2 duo.
The asrock flash programs are very user friendly and out of my experience safe to use (its nevers 100% safe afcourse but it went smoothly).
So, installed everything and all worked well, first i noticed that my VGA was running on higher temps then usual but this was no problem.. with my old mobo if i had like 60C texture problems would accure in games like oblivion.. now its running 60C without problems.
The voltage option are:
DDR : low Auto High
AGP: Low high
FSB/CPU: low auto high
I put everything on high, works stable but i dont see any change in preformance.
A big negative point of this mobo is the FSB limiter: 300 max, so from 266 - 300 isnt that much (1,86 - 2,10), the e6300 can handle much more so this isnt nice.
another negative thing is the ddr ratio.. im not an expert on this subject but standard is 2:3, so people with high fequentie ram will have a decrease of speed.. you can flash the bios to force it to 1:1 but when i tried this the PC had several boot problems and after turning PSU off/on and then started PC it started but it was instable as hell.. gues that the 1:1 bios version i installed wasent well suporting the e6300.
asrock has released a new bios version: 1.60 for users with a card like mine.. i havent had any problems but it was supposed to solve some problems for cards like mine.
Again for people with ddr and agp who dont want to upgrade to pci-e and have a budget of +- 200$ you can buy this board +
pentium D or core 2 duo.
i can reccomend it.
