Core i7/X58 Overclocking Thread

[Chicken Patty]

guys, I highly recommend for anybody using the EVGA X58 motherboard to upgrade to the latest BIOS. I myself still can't believe how great it is, improved my memory overclock amazingly and overall clock and stability of my system.

eva has huge experience and knowledge gap over me.
I am a huge nubi when it comes to memory oc.
I seem to be having some success with max oc ht off and 2k memory (1 hr prime @ 4.43 ht off with mem at 2k, timings: 9-9-9).
Not so good with ht on - why is ht on always so much harder?
Best stable ht on (if you can call 1 hour prime stable) is 4.3 ht on with mem at 1720, timings 7-8-8 - not so good for 2k memory.

don't count ya self out... with time and more trial and error memory testing everyone should be able to get more out of their system - just be prepared for alot of bios/reboots between config testing

HT on = more heat and power output it seems. My i7 920 on TRUE120 air refuses to run 3d benchmarks stable past 4500mhz with HT ON. With HT Off i can do lighter cpu tests i.e. super pi 32m up to 4652mhz !

Which should be faster - looks like I might get prime stable (both with ht on) -

#1. 31x138 for 4.28ghz with memory at 1932 @ 9-9-9-24
(just past 1 hour prime at the moment)

or

#2. 25x172 for 4.30 with memory at 1720 @ 7-8-8-21 (previously had stable for 1.5 hr prime)

1 hour prime is no not enough but it tells me I might be getting close to stable settings.
I suspect #2 is faster because cpu cycles are king but I will bench and verify.

yeah #2 but for general 24/7 apps probably won't find as much difference

before and after examples for new bios ?

before and after examples for new bios ?

well before on the old BIOS i needed 1.341v to be stable at 4.0 GHz. Now it only takes me 1.305v.


The biggest difference was that for some reason I had a really big problem running the RAM divider at 2:8. I had to run it at 2:6. However, with the new BIOS I can easily run the RAM at 2:8 and it is rock stable. THats the biggest difference i've known, and this BIOS definitely seems more stable.
