Gigabyte EP45-UD3P

[OnDborder]

This board rocks quads. I run a q9650 on mine.

 

[Janus67]

I got an EP45-UD3R for my first trip going cold with DICE, here's hoping I don't screw it up too badly!

 

[cold.nut]

finally got my D9 Dominators in to test. testing the limits on the memory before i go cold, that way i can get a general idea of what these sticks can do! i am looking in the bios to change the DRAM (CR) from 2T to 1T though..

can anyone point me in the right direction..? i can't find it in the manual, or anywhere in the sub categories in the bios.

 

[Janus67]

It should be on there under command rate with the rest of the RAM timings.

that's what i thought it was.. doesn't make any changes to the Command Rate (CR) in CPU-Z. it just a bug ?

 

[Janus67]

maybe... check using memset if it shows up properly. It's always worked for me. Are you using the latest BIOS?

 

[Bobnova]

Can't change command rate on Intel DDR2 chipsets.
1T on DDR2 takes a ton of volts and only nvidia or AMD chipsets can do it.

• CPU vCore: Self-explanatory (CPU Core voltage)
  
• CPU Termination: CPU VTT (Increase for high FSB overclocks) don't exceed 1.45v
  
• CPU Reference: GTL Voltages (Gunning Transceiver Logic voltage) automatically adjusts when VTT is adjusted.

i hope this stuff helps for those UD3P users out there. i have been scratching my head the last two sessions trying to figure the voltages out. basically VTT is required for high FSB overclocks. don't worry about Reference voltage on dual cores, raise it with quads though!

Very handy, thanks =) Im in the process of getting my q6600 G0 stable on this board. Running a bit hot with intel burn though.

keep that North Bridge real cool! it is extremely picky with temperatures!

 

[bignick]

Yeah no kidding. I was having issues with my USB3P and north bridge heat. Seems this board needs more northbridge volts to make it go. I took the sheetmetal cover off and added a 60mm fan. Got my E8600 stable at 4.5Ghz benchable, 4.75Ghz CPU-z on air. Not sure why this cover is even on there other than the bling factor

 

[Bobnova]

Bling is all, it hurts cooling rather badly. Gotta put the logo somewhere, ya know?

 

[cold.nut]

did some testing on this board tonight.. i found that disabling the BIOS feature called Virtualization Technology causes instant instability. your system won't even post after disabling that feature, so i wouldn't even bother with it anyone! not like most of you will anways.. but don't mess with it! it cost me a new chip , but i wanted it anyways !

hope this helps

I was hoping to get some help overclocking mine.

I now have this p45 board. Been playing with it for 2 days and this is the best I have so far. Many more options then the p35

How is the P45 overclocking for you now.

 

[pinky33]

Even with these settings, and as I continue to tweak it I am having stability issues. From what I have read its harder to have higher fsb with more ram.

I have increased cpu referance to 0.79 I will be attending a LAN in about 48 hours and would like a stable ~500fsb and a multiplier of 7 or 8.

Its my birthday in 12min.

try a little more CPU Termination and some MCH Core. a bump with vCore should help too

 

[pinky33]

tried that. p95 freezes computer upon start.

Something is not liking higher then 400fsb 450fsb is a little better.

with my original clocks and similar settings I was able to play team fortress 2 for hours. But battlefield 2 BC only ran for 20-30min before freezing.


I am going to change my bios from f11d to f10 tonight/tomorrow.

Hey guys! I'm having problems with my OC. I hope you experts can figure this out

Prime95 runs 11+ hours, but games keeps crashing and sometimes even the whole PC gets BSOD in windows usage.

During torture tests temps rise to 65 C.
I've been raising volts, but it helps only a little bit and now I think that won't work anymore.

^ Does your memory actually need 2.3v at those speeds?
