just to share my new OC with 2.8E

2.8@3.712@5:4@265.15@212.12
superPi 1M at 38S
all this with Clockgen and finished in window.
this OC is fully stable with dual sp2004 no error for 4 hours
and memtest 2 hours no error.

i think my IC7-Max3 still can go higher--->4Ghz barrier!
i'll do the VTT mod next week.
currently my Vdimm is max out at 2.8V. my Corsair UTT BH5 willing to suck more of it. Running at 5:4 really can show that my 2.8G can fly high.

i'll post the new result as soon as i get the VTT mod done.

i wanted to attach the printscreen but somehow it can't attach the file.
wonder what went wrong

@pengster
Good efford! Finally you can run DC:respect:
is your rig performance have increase even with lower speed+DC??
maybe you can try to disable the DC and push the cpu higher, DC somehow may lower the oc performance.

@overclockalbert
wao....hardcore ocer. GOGO Break the 4GHz barrier!!

thanx all but now i cant go past 140mhzx18=2520mhz when i try 142 or 145 it comes out the BSOD n says "page fault at non paged area" any1 noe whats that suppose to mean?

tried SuperPI 1M n got 1min1sec worst then my old timing of 58secs.btw im on 3-4-4-8,2.5-3-3-7 cant work

shud i try to bump up the vdimm even more?now mine's 2.55v from the stock of 2.5v i think..the max my mobo allows me is 2.68v

i use the same mobo as yours.
max vdimm is 2.68v but it seems you just manage to oc to 1.5GHz, then no need to rise.
is your virtual memory large enough? page file drive space is limited?

i have 1 question, is your divider is 4:5?? if 1:1 then it is quite flexible to up as you ar running the ram at speed lower than default. try set the dram speed to 266 instead of auto or 333(can be found in BIOS>advance or somewhere there) to run at 1:1 instead of 4:5 by default(coz cpu is 533fsb with ram ddr400) Hope this help.

yeah my virtual memory is 2GB if im not mistaken..my divider is 5:4 now my rams are running at DDR350 on auto mode will try to set to 333mhz later

now im running prime95 on my pc to stress it and see if its stable or not..

ran prime95 for 1hour and 6mins and had 1 error was using blend tests...looks like my ram's are causing it

Wao overclockabert,nice to see you can acheive 3.7GHz. Really the nice one.The E version is easy to break 4Ghz. waiting for you good news on 4GHz.

ran another instance of orthos and had an error after 1hour11mins dang y suddenly so unstable de..

hehe, you can expect more from that XD

i'm gathering all the infomation i got to perform the VTT mod on my IC7 MAX3 in order to run my UTT BH5 at 3.2V.
i'll need fellow forumer here to help me gather as much information as possible as to complete the MOD.

i also found out that a Droop Mod also helps to stablelize Vcore and Vdimm to help OC more success.

you help is most welcome.thanks

yes those stuffs I know but I dunno how to perform it, risky...

i've just set my DRAM freq to 333mhz but it's still 5:4 divider as shown in cpuz and the speed is still 350mhz.oh yeah i've also increased the vdimm to 2.658v [max] edi

setting to 333 means it run at 4:5, set it to 266(same as my setting), then you will have 1:1 mean your ram is running at ddr333. i believe you can increase your fsb to 160 at least, 160*18=2880MHz. Not bad already. worth try!

kayz set it to 266mhz already and yeah its on 1:1 divider now but only 140mhz[280mhz] even slower then my old 300mhz speed.nvm i shall try to go back to 2.7ghz again

ugh even at 1:1 divider cant go past 2520mhz still stuck at 140fsb.so now reverted back to auto frequency for my rams.

the max you can go on 1:1 is only up to 140?? hmm.......i thought it can go higher.

last time i cant get pass through 2.9GHz with 4:5 divider cause my ram cant get though 220+-(forgot the exact value )

once i set to 1:1, i able to boot to windows at 3.38GHz(188*18) max. My ram not even reach to its default speed.

The reason why set to lower ram speed is to give ram more room to go up along with your cpu fsb. try to push your cpu fsb higher like 150++.

tried pushing my cpu fsb with auto dram frequency and 266mhz frequency both also cant go past 142mhz could it be my psu now is a capalang 1 n not stable and all that thats y i cant push higher? sienz lah now cant even get to my ori speed of 2.7ghz.

lets say if i do not have any problems now,which is better?higher cpu clock speed or higher ram speed?

try to get your highest cpu clock with 1:1 then switch to 4:5 to see whether your ram can keep up or not.

your FMA not yet in your hand?? hmm.........

you running at 2.7GHz means 150fsb?? and your ram is 350(default 333)?? are you running with your old slower ram?? if your old ram run together with your ddr400, then its hard to push it higher.

Its better that run your both ddr400 together even not in DC. At least your ram can run perfectly at 400MHz speed. then set it to 1:1 which set down your ddr400 to ddr333. you have a room of 66 cpu fsb in order to get to ddr400 speed. 66*18= 1188MHz of OC! From what i notice, DC doesn't mean everything, just additional memory bandwidth. If you can run at higher speed like 100-200MHz higher than slower speed with DC, you will benefit more with higher speed. Nelza-ax is a good example of this case, his 2.4A prescott is running at 4GHz with 1 stick of ram, no DC, no HT. His super PI 1M is 35s and he said his sandra mem bandwidth is only 3K++.

icic...yeah my FMA not back yet just checked cpuz n it says that at 200mhz my rams def timings shud be 3-3-3-8 but i cant even set that.wont even boot if i set 3-3-3-8.so now currently is 3-4-4-7

last time when i reached 2.7ghz my fsb was 150mhz.that time i was on 1 stick kvr400 and another kvr266 but 1:1 divider so its running DC at DDR300 speeds.last time b4 my FMA kaput i managed to reach 2880mhz with that set up but 5:4 divider lah.so that time my rams was running at DDR395 now since my good psu send for warranty everything's messed up already

hmm i thought dual channel is good ie increase performance/response time all that? cuz like u know earlier i tried so hard to get my 2 sticks of KVR400 to work in DC and now im afraid if i change it again i cant get it back to DC

His SuperPI is fast because of the 1MB L2 cache
Sandra mem bandwidth only 3 K? That means he is running on single channel only

The only Northwood I know is the highest here is kcync's Northwood, 34 seconds

can you feel the responsiveness with and without DC?? i dont really feel the responsiveness. Only have different in memory benchmark. DC if not wrong it boost like 5%+- of current system. if performance for higher speed without DC is better than highest with DC, then there is no harm to live without DC.

i havent try to disable DC and push it higher, maybe it can help to squeeze somemore juice from my cpu...hehe... i wish i have FMA
