Lower than 1333mhz then u should tighten ur timings. If it's elpida u should be able to run 9 9 9 24 or 9 9 9 26 for 1600mhz. But make sure u can pump 1.65 vdimm. Else if below 1333 8 8 8 22 or 7 7 7 21 should be possible. Ram timing really not that important when ur tryin to aim for overclock coz usually u try to get a stable clock 1st then only tighten ur ram timing. Some people use lower ram clock so u can ensure the pc stability is not hindered by ur rams.

ops.... forgot to update....
i check ord...it just written "kingston" and some numbers on the chip.. no elpida words....i assume it's not the elpida chip...coz when i tune the ram speed to 1600 and timing to 9 9 9 27 1.65Vdram....it start to be unstable....
actually the ram default ord run the timing at 9 9 9 24 (1333M)....hm.........

at the end i stick the bclock to 166 so that the ram speed at 1333....and just on the turbo mode so the ratio able to hit 21 (166*21=3489Mhz) which is still not too bad tough........hehe
anyway...my Vcore at this point will be 1.2175 while the measure voltage at CPU-Z and HW monitor is around 1.23V...

that's the best i can go...XD

If bclk 200 then ur ram will be around 1200 not sure if there's 1400 ?. U can try to get higher mhz for ur cpu 1st then only tune ur ram is up to u to pick which u wanna tune 1st. If 9 9 9 27 can't then u can try higher like 9 10 9 27 or 26. I tried b4 using juz kingston chip it can still work if they r elpida or micron rebadge.

For 3.5 ur vc is juz 1.2175 mebe u can hit quite high for 1.3 or mebe 1.275. Just need to keep on trying and trying stressing till ur happy. But for me once I found my high then i juz downclock it for daily use as 2.2 or 2.4 is more than enough for my daily use. I even game wif 2.4 usually unless I feel lag then only I up the processor. Sometimes I actually wonder if we need higher than 3ghz for normal use. But it's really a big diff if u do decoding or encoding for video or processing data as it's quite time saving.

Guys
I really need some help with my system...

i m using P7P55 EVO + i5-750 aircooled with MegaShadow.
Vengeance 1600 RAM 8GB.
I manage to OC until 3.4GHz.
running all the test and all is ok.
Even playing games there's no problem.
But when leaving it idle...sometimes even for a short time...
it will get a BlueScreen error.

Ive used the OC'ers error code guide and do the suggested, it still happens.

Currently running at 3.46GHz@1.28v.

Usually the error will be 1e. 124 or 101. Sometimes the code is not even in the list!

Help plz?

Did u install newest bios ? Drivers ? (Intel INF, Storage, sound, graphics card,) Turn off all c3, c4, c5 or any c power saving stuff, intel power saving stuff in bios. Btw for ur setup u should be able to hit 4ghz with proper settings.



The attached pic is a rig which I juz revived back with below parts

I5 750 running at 20X200Bclk @ 1.275VC w/ XSPC Rasa W/B
Asus P7P55D (Need to check bios for the Voltage setting)
Corsair Vengeance 4GB X 2 running at 9X9X9X24X130X1T @ 1.55VDimm
Asus GTX 480 OC to 800 Core 980 Mem 1600 Shader w/ Aquagrafx W/B
Seagate 500GB 7200.12 X 2 Raid0
C.M Silent Pro 850w Psu

I use i5 760/RAM 4X2Gb Corsair Dominator 1600Mhz/Cooling H50 Push And Pull..Now i want u all guys..pls teach me how to OC..or give me a link to OC 10Q ..

My First OC attempt .

Asus P7P55-M
Intel Stock HSF
Intel i3 540 3.07ghz @ 3.6ghz
Elpida Chip 2GB KVR RAM (Single Channel) 7-8-7-22 1.5v
Cap Ayam PSU 450w

hi all...this is my 1st overclocking..
from i5-760 @2.80 manage to get 3.40
this is my result and it is stable when i test using IntelBurnTest
never test 3.50 yet



is it okey?

nice KVR you got there
even some 'perf ram' need 1.65V to run 1600 at such tight timing 7-8-7

its ok if you can keep the temp below 70'C during load/ stress test
is this stock voltage? or auto voltage? try push higher clock

4ghz even on air is not a problem on the i5 750/760.. to go beyond that is tricky tho.. 70-80C max load still fine .. just dont push it 24/7 haha cuz normal applications there's no chance that the CPU will go max load like during those cpu test

i lama tak main OC already hahaha.. pakai stock clock but reduced voltage (hopefully can jimat electric)

i reduce my voltage to 1.20 with the same clock speed, still ok..
i think i can push higher..

my 2nd attempt OC the i3 540 .
OC from 3.07@4.0ghz .
and prime test from 10pm to 7am without problem .

Using CM Hyper TX3 Evo .




Using Single KVR RAM .

reviving this old thread.

Any bros here with results to share for i5-760? Just recently got a bunch of 2nd hand hardware and pieced them together.

The performance and price is unbeatable. Got my i5-760 2.80GHz stable @ 4.0GHz without much effort. More to come!

it's just rather hot. my i5 760 is now at 3.5ghz on stock cooler with ease.

all sifu im wondering what is average i7 frequency can achieve with stock cooling?

To do any reasonable overclocking, i suggest u get an affordable aftermarket cooling. The weather in Msia is unforgivable

Mine

My first try overcloak my old i5, i guess i still lack of knowledge

hye, anyone done updating their mobo bios? i need help updating mine...have bad experience when updating bios on amd rig before...so need more precousion when updating this one

i just use pendrive to q-flash update my bios on my p55 last night..which method u did last time?
