Overclocking the Gigabyte GA-P55-UD3R...excellent!

The only difference between our boards is that yours supports SLI...power regulation is identical ;)

I am checking around right now for better coolers for LGA1156. I will probably get something like the H50 or some other self contained kit but none I have seen have support for it yet. They will soon! I can't wait to run some benches and do some rendering with my 860 at over 4Ghz. Those 1366 guys don't like this new socket but I think there's room for all of us in the community.

Keep us up on what you're doing man!

Stay tuned guys...i7 870 incoming...more results on the way ;)

I for one can't wait. I have got to find a cooler. The 1156 coolers are hard to find. Have the major companies come out with brackets yet?

What kind of air cooler did you use miahallen? I can only find like 3 different ones that fit.

[miahallen]

I used the Prolimatech Megahalems unit...it's one of the best air coolers on the market...it performs somewhere in between the Thermalright Ultra 120 Extreme (aka "TRUE") and the TRUE Copper. And it's reasonably priced. It also has the best mounting system of ANY air cooler to date.

They also have the 775/1156/1366 hold-down bracket available for those who already have the original version:

OK...wanted to provide a brief update with more stability testing on the i5 750, as well as my first thoughts on the i7 870 that arrived today.

First I'd like to point out something interesting I found when I swapped CPUs today. Apparently, "socket burn" may have effected me as well. Time will tell, but I believe I do show some indication of an issue here...hopefully it does not get any worse :shakes: I'd really like to know if this is a mobo/CPU/design problem:











The board is still fully operational at this time, and does not seem to be suffering any negative performance effects. (See i7 870 results below)

So, a quick update to my stability testing on the i5 750. After hooking up my basic custom water cooling system...I was able to achieve slightly better results. I was stable for about 15 minutes at 4.45GHz, but impatient as I am, wanted to try to hit 4.5GHz...so I pushed up the slider a knotch and crashed it immediately. Luckly, I got a quick screen here:



Since I knew I was at the edge of Prime95 stability, and I wanted to let it run a bit longer for you diehard stability testing guys...I backed it off a hair and did about 100 minutes at 4.4GHz...not to shabby for a $200 quad :D



When I got home from work tonight, I found a nice new retail i7 870 waiting for me...thank you Gigabyte Japan :cool: While I was hoping for some sweet cherry picked ES or something...what I got was a retail CPU off the shelf...a quick glance at the box showed this thing is a very close relative of the golden i5 I've been playing with :D



So, out came the 750, and in went the 870....right off that bat, I'm impressed. Stable at 3840MHz WITH ALL STOCK VOLTAGES forced in the BIOS :up: (auto overvolting is normal when Turbo mode is enabled)



A quick run at 4.2GHz shows that this one should also be a pretty decent clocker :cool: I'll be putting it under my F1EE in a few days.



To be continued....

Nice. The 870 seems very good. I wonder the 860 will do in the same setup. (I guess you can't test all of them) Very good post as usual.

What IS "socket burn"? just where it gets too hot and scorches the socket? Is it some kind of "short" I'm glad the board still works.

Also, Thanks for the cooler idea. Looks like a good choice!

[miahallen]

"Socket burn" is not an official term or anything, more of a possible manufacturing flaw is the P55 platform, we still do not know who is to blame, Intel or the motherboard manufacturers. See here for more details:

Does this affect the CPU too. (burn it) I have not had time to read the link you posted yet but I will. Thank you. I hope your CPU is okay. I am going to look for this on my stuff. If I see anything I willo post it, athough I will not be doing extreme OCing for a while.

[miahallen]

I think this is pretty isolated stuff at this point...seems only the extreme crowd has been having issues...but it's somthing to watch for.

Do you like using EasyTune 6? Never used it, as I tweak/overclock only via my bios.
