TPU's Core i7 Overclocking and Feedback

[DarkEgo]

Still that is alot higher that the B2's that usually cap at 215 or a real good one might hit 230. I am willing to pay more for the latest.
Fits: a few pages back you listed what boards have B3. Do you have an update to that list?

nothin new out

... i've had about 3-3.5 hours on this setup so far.

i dont think i've had near long enough to say i've been defeated



this setup is for my main rig which will be clocked very moderately to ensure good efficiency and low power draw. i am merely toyin around with this for a week before i put it to its real purpose.

maybe the numbers dont live up to the i7/x58 but i can tell you that it feels faster and thats no lie.

my ssd performs at least 20mb/s better with the OS loaded on it on my p55 than its best bench while empty on my x58. there is NO lag at all and if it could read your mind it would do everything for you without ever touching the mouse or keyboard.

i was VERY skeptical about pcie bandwidth on these p55's but after benching my gtx295s in this MATX<<<< P55 the only difference i see is the slightly lower cpu score due to the lack of hyperthreading on the i5. im almost certain that a i7 860 would perform to the same level of the i7 920 if not slightly better.

so far i can boot at 228bclk easily with only minor adjustments to voltages. lets see a x58 do that.

i think the saying "dont knock it till you try it" applies very well here.

if you remember 2 weeks ago i was advising people against p55 but now im considering selling my x58 to get another p55 setup for more serious attempts at OCing these new miniBeasts.

LOL. I must have come across more harsh than I meant to be. It's a nice platform, and I'd still consider getting an i7 860 to play with. I 'm just thinking there may be some down side to putting the IMC on the die itself. I will certainly be watching...

 

[Binge]

i think that was a typo.

i've lit 'er up at 246bclk to the desktop but thats about it. havent tried more.

Not a typo. The voltages to the IOH would make you hurl though.

 

[PaulieG]

What kind of IOH are we talking? I've never gone above 1.12v.

 

[Binge]

1.7X V

 

[PaulieG]

1.7X V

I guess I've neglected researching the positive and negatives of IOH voltages, since I never really needed to increase them much for a good overclock, and I've been so involved in WCG that I haven't really pushed my chips much beyond 4.0ghz...except for my first couple chips.

 

[Binge]

It's because I have a 920. On a 965 you could easily achieve my max bclk without even touching the north bridge voltage. The 920 QPI frequency cap is what required me to change the voltages.

 

[Chicken Patty]

Looks like i5 is something else. I've never tried for max bclk. But my board has done 223x21. Original x58 EVGA

 

[Binge]

Man EVGA takes the cake with x58 AFAIK. You've had your board since I had my Rampage II Extreme. You never once changed it and it's still throwing out sweet overclocks.

 

[Asylum]

Heres a run i did a few minutes ago.
Getting tough to get much higher without better cooling.

I hear ya bro. If I had some extreme cooling we could get this show on the road 4.8GHz baby lol.

yeah man, I never gave up on this board, right now its rockin' bro. I honestly wouldn't get rid of it. Representin' for those that said EVGA couldn't do it, woot woot

good job dude, almost at 4.6 GHz

 

[DarkEgo]

I think I am going to get a EVGA SLI LE if I can ever get my UD4p sold.

 

[mastrdrver]

Maybe I should have been more specific in that what are max bclk using sane 24/7 voltages. Still nice to see some very high bclks compared to what you see with the prior 2 steppings.

I need to flash mine to the latest BIOS, I heard it's even better than mine which is the one before. I can always switch back if anything. I'll keep you guys posted on that

 

[johnnyfiive]

Yeah, but BCLK doesn't mean much if you can't get more than 4.2ghz stable. From what I saw with both you and Johnny, neither of you could get bench stable any higher. Not to say that is bad or anything, but certainly gives no reason to switch from an i7 by any means.

What I'm impressed with is the i5/i7 1156 specific memory kits, especially Kingstons HyperX kits. 1600MHz kit @ 2130MHz so far, rated 8-8-8-24, running at 9-9-9-24 at rated 1.65v. Thats pretty awesome.

As for stable oc's, 4.22GHz is benchable but I don't have too much time to find its absolute max 100% stable frequency. I've got another board to run through then I gotta get these out for reading, so once thats out of the way I can spend plenty of time fine tuning voltages and displaying the full potential of this 1156 platform.

What I want bargain targeted people to understand is the value of the i5 750. If you guys on a budget are still considering a Phenom II 955 or for some reason a 965, stop wasting time and go with a i5 750 setup. It makes every Phenom II look slow. It trumps them in every area. Clock for clock, overclocking, power consumption, EVERYTHING. In my opinion, the i5 750 it worth $230+, at $199 shipped its a damn steal.

Now, i7 9xx x58 owners, wait for Gulftown. Theres no doubt that x58 > P55. Fits says it feels faster and hes right, thank the IMC for that. But I personally wouldn't sell off my i7 x58 rig for another P55 rig, Gulftown has my attention and I'm sure a 6 core 12 threaded CPU will make any i7 9xx or 8xx look like childs play. 32nm ftmfw.

very nicely said and well put together. I wouldn't sell my setup neither, but I went from having nothing but AMD, to having three intel rigs ATM. AMD is great stuff, I love them. I wanna build an AMD rig just because I wanna mess with their new CPU's. But with intels new line up, it's hard to build an AMD just because.

 

[Chicken Patty]

I brought down voltage for my 24/7 crunching settings.


used to be 1.341v

 

[Jakethesnake011]

I finally was able to get my hands on a classified, I can not wait to get in in and running.

 

[johnnyfiive]

I want a classified 760 too, I may sell the DFI board soon, although, its a damn nice board, but these numbers peolpe are getting on the classified... dang.

 

[Jakethesnake011]

This is out of the ox with the 5870, going to try and OC it, but I am only able to hit 900Mhz on Core with ATI catalyst software, so I need to find other means of bringing the clocks up.

 

[Jakethesnake011]

I was hoping for better

 

[johnnyfiive]

Eh, synthetic benches, blah blah! Lets see how it does in some game benches Jake, I'm sure that will bring your spirits up about your awesome 5870 purchase!

How you like the board?

I agree. Game with it a bit and see how you like it bro, keep us posted.
