Then how much voltage you put on RAM? memory ratio and QPI ratio~~~

guys, sorry out of topic. but shud i take i7 870 or 860 which is rm60 lower? which one overclock better? thx

take d higher clock is better..
y? higher headroom for OC..
but again, it depend on ur luck..
if u got d best chip, it can go beyond that!!!

Hey gurus, I got a motherboard choice question.
I'm looking for a good OCer board that is not too expensive and support SLI. Which choices do I have that hopefully gives good OC performance while below RM 550(preferably <500)
I've found a few but most seem to support CF only
msi p55-gd65
biostar p55 t5-xe cfx-sli

are there other boards in this price range and which will OC the best?
thank you.

Well,if you are not aware,you can make any mobo with dual PCIE slot to run SLI with mod

Just to share, probably something fun for ASUS owner..

Price look attractive

Currently running an MSI P55 GD65 bios 1.9 mobo with an it 760(hyper 212+ stock fans + ) and team 1333 9-9-9-24 ram. Been trying to OC it for a few days

Followed the i3/5/7 OC guide (3 time IBT stable then increase)
Lowest cpu multi (X9) and other ratio max bclock at 215 (VTT 1.2) didn't go higher voltage yet
max ram 762mhz (190*4) vdram 1.65


Here's what i got so far
So I've oced the rig to 3.8Ghz stable with power savings & spread spectrum off at these settings
Memory Ratio 4
QPI ratio 16
bclock 190
multiplier 20
Memory Setting manual (but all stock settings) 9-9-9-24 88 1T
vcore 1.17 (fail linpack Max if reduce by 0.01)
vtt 1.203 (Fail linpack if reduce by 0.01)
dram 1.651
low vdroop
Did some testing to find lowest voltage, these settings are 7 hours OCCT blend stable at 60C. Intel burn test (IBT) Max 5 runs 65 or higher depending on fan speed setting i think.

How are my settings
Trying with all power savings @3.8ghz on for now. Will stress test when i go to bed later. HW monitor indicates a large drop in wattage with them on
Just now tried vcore 1.22 190x21 fail linpack, no time to try 4ghz since 3.8 is good enough performance and temp .

One gripe i have is my memory wont reach windows at 1600mhz (bclock 200). Tried VTT 1.22 vdram 1.65 at above settings with BSOD.
How should i try to tighten my timings or increase the frequency. Should i try a higher bclock and see if ram reached bclock hole?

Hi guys,just try to OC my proc. Please guide me a bit.

Specs:
Intel i3 530.
Intel HSF
OCZ Gold PC3 1333
Biostar TH55-HD







Stock cooler in use.

I've seen a lot of different CPU multiplier to get 4GHz,most use 20-21-22. Which one is better? Higher multi,low BCLK or high BCLK,low multi?

You should run Prime95 / LinX to test the stability..superPI doesnt stress the processor and other components for long. I'd recommend you to change your HSF before going further. With your performance rams , i guess >4.2ghz will not be a problem Mine managed 4.1 ghz with value rams and cheapo cooler

Thank you bro for the help.

Well,what do you think of :
1-CPU multiplier,should i use the highest (22x) or lower?
2-QPI Link,set auto or highest?

TQ.

1. Doesn't matter, if you can do high BCLK, low multiplier, or low BLCK, max multiplier, both ways pretty much the same. High BCLK may requires more core voltage and MCH voltage.

2. Lowest guarantees stability. Try to match the QPI to the default QPI or nearest.

hye guys here ..

im new in Intel

may i know what setting to disable Idle mode?

mean i want every second my clock will runing at just one speed ..

my spec as u can see at my sign

EIST?

ok tq

Disable EIST C1e Cstate/step , might be different for other mobo

Added on October 19, 2010, 11:30 pmI tried going for high bclock while aiming for tighter memory timings..
Because my ram stubbornly against 1600mhz! 195x4 also won't reach windows

4.0 210x19 was ok for 3x IBT but temps going 75C max ...
3.8ghz 211x18 was similar to current setup but slightly lower vcore.. Don't notice difference in temp maybe 2C higher

However fail to enable EIST, I think its sensitive to the high bclock.
Since power saving cant be turn on, going back old setup

Don't think I'll up the OC too much without memory/HSF upgrade, maybe focus on GPU OC...
Need to fine tune memory timings using old timing stated above

Anyone have similar setup to compare?
Thanks

hi, can share what the lowest BCLK to oc i7 860 stable at 4.0Ghz ??

and what is the best timing for ram ?

Hi sifus. Have a quick noob question, can't see to find the answer over google (maybe not searching properly). Is the asus p7h55m le mobo overclockable? Can't seem to find any guide to overclocking it. Just looking at setting a higher clock speed on stock Proc HSF. Thanks

@seanlimys,

what's your ram timing and vdimm?
you leave all the voltage to auto or manually setting it?

rgds,
