caintry_boy Posted October 21, 2009 is there something that changes the multiplier automatically? It seems windows starts with the 20x multi and the after pit and 3dmark test it scales back to 12x multi..... Thats where my test seems to slow down in is the CPU... http://pcpitstop.com/betapit/sec.asp?conid=22845678 heres the lastest test...top 1% or better for everything but internet new 3dmark with o/cing http://service.futuremark.com/compare?3dm06=12266712 Make certain that the vcore and QPI are within .5v...........

ctran503 Posted October 21, 2009 upped the multi to 21... http://www.pcpitstop.com/betapit/sec.asp?conid=22845024 something is lagging the internet right now...so ignore that part of it., Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 (edited) still getting used to this but i keep hitting a wall at 4.0+ and stable... 4.0 it stable prime95 for 20 minutes+ i now have to figure out how to up the clock and get it to boot correctly...and stabilize it...i know this chip can hit 4.3+ but i cant seem to find the right settings...it always freezes up on the main boot screen... well its all trial and error...

KRAM Posted October 21, 2009 new 3dmark with o/cing http://service.futuremark.com/compare?3dm06=12266712 Very impressive score for a single card. Quote Share this post Link to post Share on other sites
BigJoe5434 Posted October 21, 2009 try OCCT for an hour, its a pretty intense stress test. an hour of OCCT is supposed to mean very stable http://www.ocbase.com/perestroika_en/index.php?Download Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 (edited) I need some tips here....on overclocking over 4.0ghz it seems i hit a snag on start up when trying to go over 4ghz I have my dram settings currently @ 7-7-7-20 up to 4ghz. when i go over 4ghz i try 8-8-8-20 or 24 and still no boot i change my voltages to about 1.32-1.34 when going over 4ghz...still no boot... I dont know whats doing on...or if i am missing a setting... Edited October 21, 2009 by ctran503 Quote Share this post Link to post Share on other sites
KRAM Posted October 21, 2009 Try 200x21 with the 1.32-1.34 voltages and see what happens. Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 Try 200x21 with the 1.32-1.34 voltages and see what happens. i get in but not stable... http://pcpitstop.com/betapit/sec.asp?conid...;report=Summary the test reports a wrong CPU clock...but its still okay to run a pit test but nothing else.

terry1966 Posted October 21, 2009 (edited) ok i don't know if these terms are the same for your bios and cpu(can't remember which one you have) but here's a couple of things you need to know and remember when overclocking an i7. 1:- everything is a multi of the bclk 2:- uncore must be set to 2 times the memory speed at least. not sure of your memory speed so to start with set it to 6 times 200 = 1200 mhz set the uncore to 2600 mhz set cpu to 20x set qpi to lowest multi think that's 32x leave all voltage settings at auto except the ram, set this to 1.64v and set the cpu voltage to 1.275v now try and boot if it boots and is not stable increase the cpu voltage a notch, keep repeating this until it's stable. when it's stable you can increase your memory speed if it becomes unstable you know now it's because of the memory so might need some tweaks on settings. edit:- if you still can't get it stable at 20x200 you might need to manually adjust the qpi/dram voltage to around the 1.4v mark Edited October 21, 2009 by terry1966 Quote Share this post Link to post Share on other sites

ctran503 Posted October 21, 2009 Are you stable at 200x20? yes...prime for 1+ hour @ 200x20 @ 1.26v Quote Share this post Link to post Share on other sites

KRAM Posted October 21, 2009 yes...prime for 1+ hour @ 200x20 @ 1.26v Then you need more vcore then what you have been giving it. Only thing that has really changed is the cpu. Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 (edited) Then you need more vcore then what you have been giving it. Only thing that has really changed is the cpu. i dont know...anytime i try past 200.... no matter the volts it wont boot... its kinda crazy...

ctran503 Posted October 21, 2009 (edited) Bumped it up to 1.33 just for stability check and i may draw it back... 75C Cpu... 85-90 across the cores... with prime 95 load Edited October 21, 2009 by ctran503 Quote Share this post Link to post Share on other sites
KRAM Posted October 21, 2009 Do you have Everest? If you do, load up the stress test and have it showing the core temps and voltages, take a screen shot and post it. Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 Do you have Everest? If you do, load up the stress test and have it showing the core temps and voltages, take a screen shot and post it. yea...i pulled the temps off there...i think im going to reseat this cpu....ill be back with you guys in a little while..

terry1966 Posted October 21, 2009 (edited) try a lower multi something like 15x for the cpu for higher bclk than 200, if it still doesn't post i'd think it's definitely a memory/uncore setting somewhere that needs adjusting. edit:- your on air so i'd think those temps are about right. with the standard heatsink and fan my temps were well over 90c at 100% load even with a mid overclock like 3.6ghz Edited October 21, 2009 by terry1966 Quote Share this post Link to post Share on other sites

Currently stress testing it....will post after 10+ minutes of stress testing... Quote Share this post Link to post Share on other sites
ctran503 Posted October 21, 2009 (edited) 13 minutes is stress testing @ 4.0ghz w/ 1.18v but stil hitting a wall @ 4.0ghz+ Edited October 21, 2009 by ctran503 Quote Share this post Link to post Share on other sites
KRAM Posted October 21, 2009 Nice, what did you change? Quote Share this post Link to post Share on other sites
terry1966 Posted October 22, 2009 still think it's the uncore v ram setting that you need to adjust to get over 200 bclk especially now you can get 4ghz with so little voltage. very nice 1.18v Quote Share this post Link to post Share on other sites
ctran503 Posted October 22, 2009 (edited) I got 2 cpu's to play around with... and it seems the second one performs a whole hell of a lot better. now its a matter of testing to find out how to get myself over the 200bclk.... still on factory timings @ 7-7-7-20 Edited October 22, 2009 by ctran503 Quote Share this post Link to post Share on other sites
KRAM Posted October 22, 2009 Sounds like a replay of my situation. Looks like your second one is a keeper. Quote Share this post Link to post Share on other sites
