PSU help

Well its got that motherboard cover that raises temperatures as airflow cant get to the IC's underneath, its missing the Z68 features (SSD caching, Lucid and quicksync) it wont be Gen3 to the second GFX slot like the MSI is. The MSI has a one touch OC button giving you an instant 4.2Ghz, its called OCGenie.

Its also more expensive. If you want something "Black" to achieve a similar effect,

what are they like to overclock?
 
The Asrock has a feature in the BIOS called Turbo50, allows you to select from 4, 4.2, 4.4, 4.6 and 4.8Ghz and the board sorts the rest out for you (but you will still have to check for stability using prime95 or Burntest)

The Sabertooth and the Asrock both have a 8 phases VRM setup for the CPU, the Gigbayte UD3P has 12 and the UD4 has 16 just for the CPU, more phases = better as they share the load and run cooler.

Overclocking also depends on the CPU, not all can manage 5GHz etc, but overclocking the UD4 with the same CPU as when I use to use a Asrock extreme4 got higher results. The Gigabytes also recover from bad overclocks better and dont need a clearCMOS as they have dualBIOS so it can go back to the last good settings and flashing the BIOS is painless, if theres a power cut while you do it, the second BIOS takes over and re-flashes the first.

Theres also a UK based RMA center in Milton Keynes with Gigabyte with a 5day average turnaround time, saves posting a board to another country.


Edit, one more thing is theres Load Line Calibration (LLC) on the Gigabyte boards, so you can set this between 1-10 and it combats the Vdroop or can increase Vcore on the higher settings (cant remember if the Asrock has this).

so how would u overclock the ud4 for a i5 2500k?
 
Well I set the CPU ratio to 48X, added a bit of llc, manually set the ram timings correctly as my dominators don't have a xmp profile. then boom, prime stable.

I also have a 5ghz profile saved in the bios user profile that needed some added vcore and a tweak of the pll voltage, this is stable.

I can also run Super pi at 5.2 ghz but haven't got it stable under prime 95.
 
I completely forgot, there's is a program included with the gigabyte boards called easytune6, this has three set overclocks to select, think the highest one is 4.2 or there abouts.
 
What Stulid said about xfx having a northampton address could be important.

I just returned my Corsair HX750W to the Netherlands for an RMA and it cost me about £40 in postage!!
