use gpu-z to verify ...... gpu-z is more accurate than windows err..... bla bla bla ........ nice oc bro .......

for E5400, anything below 1.4v is safe. try stay below 1.35v.

I can get E5800(Original 3.2GHz) to 3.83GHz(333MHzx11) @ 1.32v no prob. I think u should be able to get pretty stable below 1.35v.

E5 and E8 not same bro. E8 can stay at higher clock at low voltage
or depends on stepping. some stepping has lower voltage then others at same clock

i wish there was a thumbs up or like button in this forum .

what the heck u talking about? E5800 is the same chip as E5400.

sorry bro miss read your reply as E8500, actually yours was E5800.
sorry again for miss understanding

no..u misunderstood me..im getting exactly the speed that i have OC'..

just that figure does not update..

ignore the windows one ...... they always like that ...... sometimes won't update .....


wait ....... wait the minute ....... u mean windows experience index ?

no la..did u even see the picture? the one that i circle with red..

last time im using different Core duo 2Ghz..i oc until 2.67ghz and it shows like this 2.00Ghz @ 2.67Ghz

lololololol...... sorry bro ...... kpale byk pening plak skrang ni camner la bleh xnmpak ......

manage to pass 8 hours stress test with prime 95. with 0 errors 0 warnings

my cpu OC from 2.7 to 3.5 (260x13.5)
before this not stable cause of ram frequency.

team elite ram very noob 1 lol.
i have to lower the timing from 6-6-6-15 to 7-7-7-20 (390mhz)
my ram rated at 667mhz DDR3.

gonna test with dual ram kvr 2gbx2 soon with tight timing.
team elite ram very fragile 1.

my mobo not so good in oc.
can't change volt at bios
mobo model : msi g41-p28 http://www.msi.com/product/mb/G41M-P28.html

does lowering ram frequency affect performance too?

I think u should stop oc there ...... already nice numbah ........ great oc bro !!!

what u think about RAM, is it bad ratio?

nice OC there with very low vcore
i just wonder what is your default team elite timing and speed...
CL6/CL7 is consider tight for ddr3 (normal ddr3 nowadays rate at 1333 CL9)
tight is better than loose timing. isit your ram can run only at 800/667mhz due to LGA775 proc?

lowering ram freq sure effecting the perfomance (in benchmark)
in real world, i doubt we can notice any diff... i normally test the the ram perfomance using
aida64 memory benchmark to find the best score. this is not the best software but the test
is simple and fast. can get the result in a couple second only

example (AMD phenom ii system)

i have no idea to maybe cause of my mobo or proc

currently i change to 1:2 ratio 6-6-6-15 (500mhz)
my ram not stable if over >500 mhz

i dunno what happens my elite ram, CL-value 9-9-9-24
maybe i shud change manually in BIOS?

CL9 so speed should be 1333Mhz... hurm...
try change in bios, increase ti vdimm from 1.5-1.6v

my mobo can't change volt

OC in BIOS not software.

3.5 is pretty much can be run on stock voltage on E5000 series. E5000 are knowned to run @ 3.7-3.8GHz easy. *45nm. Extreme part may be 4GHz. but that req a lot of voltage. u can try 3.7GHz. I am not sure if u can hit 3.8 with decent voltage or not since mine is a better chip E5800.

667 RAM should have no trouble feeding 333FSB, Check ur RAM ratio in BIOS, make sure is below 667.

ya i oc use BIOS.
yea my ram ratio now is 500.

Without upping vcore 3.5-3.6GHz is max u could go. With vcore up 3.8 is easy.

my E5800 is stock 3.2GHz at default vcore 1.25v

3.73GHz(266x14) @ 1.29v
3.83GHz(333x11.5) @ 1.325v

I tried 1.3625v(intel's max) @ 4GHz, failed so far.

I never need to tune my ram, just change FSB/ Ram ratio to keep it at the spec.
