Core i7/X58 Overclocking Thread

[bmilos]

I have had the same issue.

[zlojack]

You might wanna make sure that vista didn't put your rig to sleep. It seems on my system since I upgraded to i7, vista has this nasty habit of changing my settings to go to sleep after 30 min. I orignally thought my pc was shutting down till I noticed that.

Something to check on...

Nope.

Turns out there was some work done on the power lines near my house.

I specifically asked my wife if something weird happened to the power today and she said no.

So my rig is fine

My marriage...

my stock clock temps are approx 29c idle and 49c load.. is that pretty normal?

[sonofander]

My wife crashes my rig all the time! She turns on the toaster oven and her hair dryer and poof!

I keep telling her to warn me but... Nothing worse than loosing and hour of progress in a game to your wife's hair dryer

Seems that all the revision C0/C1 920s are in Europe and England. Anybody know of one of these uber chips being purchased in the United States?

I bought mine at Central Computer right here in down town San Francisco... (the Howard location).

priming at (180x20) 3600 now with 1.23v and loads at between 57c and 60c (CM V8).

[Splave]

Got mine from newegg

I can prime all day at 20x180.. after you finish try running linpack

ok - I will try linpack. I have been out of the whole OCing gig for more than a year now because I haven't had a new system to play with.. :p anyways, kind of getting up to speed on all of this stuff again..

WTF.. i can't get my damn board to do 200 b clock!!! AM I JUST UNLUCKY OR SOMETHING...

i lowered the multi and did 200 and still no go.... even ran 1.5v through cpu just to make sure that wasnt the limiting factor

which voltage should i be upping to go with the base clock!!! would that be qpi or what!?

what is the batch number on your cpu? can you get a 180 base clock?

[nosboost300]

where do find batch number??

as for 180 b clock... yes i can do 180.. highest bootable bclock is 181

it would be on the retail box it says batch next to it. if you got an oem chip the only place you'd find it is on the chip. the number would be similar to what you see next to my cpu listing in my sig.

[nosboost300]

3837a769 would be my batch

i know its not the cpu... cuz i even tried 200 b clock at 1.56v and no go

cooled with an apogee gtz

[D3mon_Hunt3r]

That's weird most ppl are reaching 210 max block some even more.

Upped QPI/VTT?

[MJOzolins]

I've gotten mine up yo 215Bclk, not sure if I will actually run it at this though. As it is now @ 200 Bclk my 1333 ram is running at about 1606 @1.34v memtest stable. Not sure It could handle running much higher then that if I bump up the Bclk further. Guess I could drop my ram down to just under or around 1300 tho. Not sure how much of a difference that would make.

Am I missing something, I seem to see some people posting multipliers of over 20x on 920/940's... Its locked at 20x isnt it? Or is the p6T deluxe just fail?

Also was wondering what people were running as far as CPU PLL v, I have mine up to almost 1.9 @ 200 Blck x20 (4ghz), vcore 1.375. Is it worth upping CPU PLL further to get more stable @ lower vcores? Not sure what exactly is high/low for CPU PLL voltages.

[WaterFlex]

More Everest results please

QPI/VTT at 1.9V is suicide for 24/7!
Up to 1.65V should be relatively safe (as safe as ocing can be ), but 2V kill an i7 - not to say - instantly, but quite fast. That's was saaya was telling in one of the threads concerning voltages.

Yea sry about that, I definatly meant CPU PLL voltage
Really not sure how much the pll voltage effects everything.

Anyway just screwed with it a bit, Can post @ 215 Bclk (No windows)

Windows @ 213 (low Multi High vcore)

Windows @ 210 (20x multi)


Anything over 1.4 vcore is a bit high for me, I guess Ill have to see what I can get running stable
These chips dont seem half bad so far, at under $300 the 920 seems great, glad I didnt shell out extra for 940/extreme.
Odd how different some of these chips are fairing so far, im really surprised some people are stuck at 180 bclk

Ill throw up some benchies once I get something fairly stable

Please post the following:

CPU Mult
QPI Multi
Uncore Mult
Memory Mult

CPU V
Qpi/vtt V

I'm thinking that it is an issue with one of those multipliers that is causing you to not boot up at 200 Bclk.

[Xello]

When ya'll say 'i can reach this bclock' etc, are you talking about 100% stable bclocks or just benchable bclocks or just bootable bclocks?

Max i've booted is 222 but i had to drop to 213 for 100% stability, with 1.44v QPI.

for some reason, I can't hit 210 Bclk unless my qpi is like 1.7+

[Xello]

Ummmm yeah i wouldn't run that high QPI

I don't want to go near 1.5v myself, though really some knowledgeable people are saying 1.65v is fine... But i mean if only 1.4-1.44v can get me 213 i think i'll just take it and be happy

Jumped from my 187x23 to 192x23 - Windows wouldn't even load So i dropped one at a time and i'm currently @ 189 bclk which is looking to be my max stable with 23x multi. Any higher cpu mhz and i will need to go over 1.5v which i just will not do. This gets me 4.35ghz~ though and 9.6s~ SP 1m which is not bad, and still loaded at 59c (HT off) I still think i'll end up dropping to 1.3-1.33v and sticking with the 4.1ghz for 24/7.

If you guys are hitting 210+ on less than 1.6, how are you doing it? Would raising vcore help? What are you using for qpi pll?
