Re: GA-EX58-UD4P bios F6 memory timing settings without CPU OC?

Hi,

Just make sure your uncore multi is at least twice that of the RAM. So if Ram is 12, you need at least x24 uncore multi....

To see what the timings are, you need CPU-z or similar. BIOS does not show actual set timings...

Apart from setting the RAM at spec timings + voltage, you will probably also have to increase QPIvtt voltage. (try 1.25 to 1.35v...)

Re: GA-EX58-UD4P bios F6 memory timing settings without CPU OC?

C3D76, thanks a ton for the advice. I've read a lot on memory timings, but I'm still pretty green and I'm uncertain about the way the I7 accesses memory and vice versa and what this might mean to setting memory timings.

So, here's a real dumbass question, but does raising memory speed improve performance even if the CPU isn't OC'd??

Re: GA-EX58-UD4P bios F6 memory timing settings without CPU OC?

Thanks again man. It turns out that the 4U rack enclosure I used won't handle a good CPU sink with 120 mm fan. It's about 10mm too short, so for now I'll be stuck with the stock i7 stock sink/fan. I'm not sure how much OC'ing can be done with that setup. Can you point me in the direction of some good documentation on that?

Re: GA-EX58-UD4P bios F6 memory timing settings without CPU OC?

I can only link you to overclock guides, that are pretty limited since the hardware just came out. I would think you may be able to get a little overclock going but not sure how much

Here is the few guides linked in some posts here I know of, but again they are orientated towards overclocking >>

There is smaller heatsinks that may still work much better then a stock one, did you look around good and long? Just wondering
