Gigabyte GA-EP45-UD3P & TWIN2X4096-8500C5DF

 

I have the above motherboard, and 8 gigs of the TWIN2x4096-8500C5DF Memory. I am also running an Intel Quad 2 Q9650.

 

I was using 8 Gigs of (adata) 800mhz memory. I upgraded to the corsaid memory 1066mhz.

 

Testing, there is no difference in speed. I set the motherboard to manual, with 5-5-5-15 timings and 2.1v, but still no difference.

 

What am I doing wrong? Was it even worth me upgrading?

 

Please advise.

The 800mhz memory settings were just stock spd, and I use pcpitstop.

 

All other motherboard settings are the same. No Overclocking.

 

 

Although with the (A/Datamemory) 800mhz, I was able to o/c to 3.6ghz, but when I tried with the corsair, it won't boot.

hi, Well, I already got rid of the (adata) 800mhz memory.

 

But when I did the pcpitstop testing, the memory speed was exactly the same.

 

I am using 4 modules (2gig each) of the corsair, just like I did with the (adata).

 

Not sure why there would be no difference and why I cannot overclock with it all.

 

???

I am a systems integrator and have installed and built systems based on Gigabyte technology although I prefer ASUS. At any rate, Gigabyte are fine boards, but I set my values via BIOS.

 

What speed of an overclock are you looking for? Would you like settings specific to your system with overclock? If so, you must follow my instructions including the Everest.

I would think I could get a minimum of 3.6 with the processor / memory I have.

 

Why would I be able to overclock with the 4 modules (total 8gigs) of the 800mhz (Adata), but not the 1066mhz Corsair?

 

I upgraded cause I thought Corsair would be the better way to go, but I am not able to move off stock without a blue screen.

That doesn't make any sense to me. I can't see how memory running at 1066 can test out as fast as memory running at 800Mhz given the same externals. Transfer speed is transfer speed. Ram does no operations and is merely a storage repository with a certain speed.

 

That's like saying that two cars on a highway with one going 80km/h will reach a certain spot faster than one going 100km/h.

 

Look to your settings and software. If you still can not get joy out of the memory, then exchange it for something else and retest. I think that your testing procedure method is flawed. Doubly so when you do not post your system memory speed on Everest and post both 6400 and 1066.

Ok, I sent two modules back under RMA. So I am using JUST two modules.

 

Problem is memory will pass memtest fine. Then a few days will go by and it will start consistently failing. I have tried 800mhz and 667mhz as well, still happens the same way. At times, the computer will not even boot up, so I have to remove one mem stick.

 

I since have tried another brand/model memory, 1066mhz and it has no problems so I know it is not the motherboard, which is new as well.

 

I have not adjusted any other settings besides the 2.1 volts, 5-5-5-15.

 

With two of these Mem Sticks, not Four, do I need to adjust anything else? And if I had four again, do I need to adjust anything else?

 

I have seen others having the same intermittent problems with these Dominator memory sticks, what could be the issue?
