TPU's Core i7 Overclocking and Feedback

i want to document what im finding so maybe it will help someone.


1. (on asus boards)QPI/DRAM voltage drives the bclk(voltage wise).
when you up the bclk you need to up the QPI/DRAM to "drive" the bclk for stability.

2. vcore is important but is much like woldale chips, low voltage is better. 4ghz can be attained at 1.38v easily once you find the rest of the settings in the right order.

3. Vdram is important 2nd to the QPI/DRAM voltage. i have found that Vdram needs to be set as close as .5v higher than QPI/DRAM at all times for stability. if you follow this rule finding stablilty is pretty easy.

4. auto setting is your best friend. if you dont know what to set something at, auto is your friend. trust me, it works. the board has its own brain and knows(almost) what it needs.

5. manually setting ram timings makes finding stability a PITA. dont do this until you know how everything else correlates.

6. good and i mean great ram is highly recommended. my gskill el cheapo's work fine but for OCing like i do they suck ass. i sent them back and ordered some gskill blk PI's 1600mhz with D9GTR chips. they are FAR better than the Elpida chips on the cheapo gskills(red tri channel kits).

7. 775 coolers suck ass for i7 chips. i seriously think someone needs to start from scratch and design a cooler made to dissipate 260+ watts of heat. i know it would be pretty big but thats what needs to be done. notice how the TRUE is the only cooler successfully cooling the i7's right now. it is very good and can dissipate a TON of heat very quickly. im sure many will argue but my question to you is... have you tried your cooler on an i7 yet? if you cant say yes then i dont want to hear from you telling me how great it is. test, measure, document and then prove me wrong if your that sure about it.

fit I have to completely agree with #7. As it is very true. I've also noticed that Auto settings for voltages are your best friend dude, I use it and it works great. Other than that I can't comment because I don't have any experience with.
 
mmmmm bandwidth...

guys, just in case you didnt know, giorgos posted this in another thread, don't know if it will help, but i'll just update you guys incase you havent tried it


to all of you i7 users....
run 06 with C-state disabled....
 
cool, just incase somebody was not informed, maybe they could have tried that out.

That guy with his i7 965 has no idea how crazy these 920s are to OC stable to 4.0ghz and beyond :laugh: He's got it EASY

just stabilize your bclock to 190-200 and you have it....
doesn`t matter if it`s a 920-940-965...
and believe me...i have a lot more idea than you think...;)
 
cant get it there though. there is NO SETTING that get 200blk stable. me and binge have identical setups and have been trying for days.

I'm bench/normal operation 24/7 stable at 200. I need to get to 210 to get 4.4ghz or 215 to get 4.5ghz. We don't have an unlocked multi ;) you do.
 
i have tried it all. i can boot into windows but it locks under any load at all.
 
hey fits settings are there.....
you just have to find the correct combination...



dont expect to get an 920 to 4.5ghz with plain water.....they do 4.5-4.6+ with sub-zero..

Dunno if it helps but here (translated from Portuguese).
 
yeah but lets see some 3dmark runs at 4.5. i bet it wont.

No shit but it's not like it can't be done. I've gotten 3/4 the way through 3Dmark Vantage on those settings. It failed at the end of the 2nd CPU test.
 
real superPI 32m.

that wprime is a joke.

make sure you get the XS moded super PI
 
both of them....wprime32,super pi 32m and wprime 1024.....
then i`ll give you credit for very good overclocking...
 
I can do 4.4ghz with those. But not 4.5 :(

Doesn't mean I won't try!
 
id be hapy to get anything over 4ghz to run benches. im SOOOOOOOOO sock of battling this POS. i want to sell it and get a p6t6 revo already.
 
Binge of course you`ll try.....
that`s the point....
the bottom line is from the point you bought the 920 you`ve got a limit to your o/c.....
no matter what you do you wont go over the barrier of 220-230 bclock....
which means ~4.6-4.8ghz in the best case scenario...
 
tell me how to get there! this thing is killing me!
