TPU's Core i7 Overclocking and Feedback

[mafia97]

increase the voltage just a little still failed
here are some pics
thanks for help
binge dude pls dont hit against wall i was just asking
u must be having 1000 times my knowldge but i m still learning
thanks anyways

Whats your ram voltages and timings set at and what divider are you useing?

 

[mafia97]

ram voltage 1.50 (default)
timings 9-9-9-24
which drivers?
but i already have all latest drivers and bios fir all the things

 

[Binge]

stock voltage for an i7 920 C0 is VCore 1.25V QPI/Vtt 1.21V

 

[mafia97]

what is a divider
bios vcore is at auto and these are optimised settings according to bios
my temps at this voltage also touch 50 so if i increase the voltage to 1.25 they may increase further
thanks for replying

 

[Binge]

I'm stating a fact that the intel recommended voltage for stock i7 920 C0 chips is 1.25V on the vcore. If you want better temps, get a better cooler.

 

[mafia97]

failed at 1.25v too
it always fails as second run finishes
any other advice

Best advice to hit clocks up to 4Ghz: use automatic settings.

My C0 as well as my D0 chip easily clocked up to 3.83 on auto.
Lowering your memory multiplier when you do that is a good idea though, as you will end up trying to boot insane speeds on mem. I accidentally booted up with 2Ghz mem on 1066 sticks once

Thrack... he's failing at stock. Return the chip to where you got it and get a different chip.

He's failing at stock because he is twiddling with voltages he should not fiddle with until he is way above stock... Or did I miss something?

You missed something. He was failing at auto, which was 1.12V which is too low for a C0 i7. Stock for a C0 is 1.25V, and that even fails.

I don't think any x58 board will have a defat vcore that is too low for any i7 chip. Even c0's can under volt well below what his vcore was at stock. His CPU is def. Not good. I'll get it replaced if I were him.

Reseat the cpu and memory. Can you pass memtest?

 

[Fitseries3]

reset the bios.

press F2 at boot and let 'er boot to winders.

I want to know what setting your using in Intel Burn Test. Standard? Reason I'm asking is because I only have 3GB of memory, if I use the next option up (High), mine will fail because I run out of memory to complete the test. Standard however, I pass that shiz all day long. Also, put your memory to 1.65v just to be sure your memory is getting enough juice. Intel Burn Test is not only a CPU tester, it will heavily test your memory as well due to it being a linpack test. If you memory doesn't have enough voltage you will fail that test without a doubt.

 

[Asylum]

Also check your recomended voltage for your ram it may be set to low.

 

[Fitseries3]

i say stop wasting time doing stress testing and enjoy the pc for what it was intended to do.... whether it be gaming, benchmarking, video encoding, server, or whatever.

 

[mafia97]

thanks jonnyfive read ur post and ran it at standard
passed the test very quickly
does max stress fail due to ram limitations
heres the pic
thanks others too

Thats good to hear. If you look at your " available RAM " within Intel Burn Test, you don't want to exceed it. So "High" or "Very High" may utilize 3-4GB, I can't recall which uses which, but I think you get what I mean. Glad it passed.

 

[Fitseries3]

maybe you need more ram....

overclocking

did some overclocking after some test passed
in linpack test when i did custom settings and pput ram 3500 or 3000mb it failed but when i put 2048mb it cleared
so i clocked it 3.2 ghz by reducing voltages a little and it passed linpack test
here are some pics
more advice would be greatful
i would be going back to 3ghz now
thanks for all the help

Use LinX for testing , it's better

If it doesn't pass the test when using all memory , then your overclock is not stable. It's very simple.

And if it's not stable , you need to raise voltages.

 

[mudkip]

For a beginner like you it's better to start from the beginning.

Set QPI multiplier to x36
Memory to x6
Uncore to x12

Then set the voltages and try to overclock your CPU.

IF IT'S NOT STABLE RAISE VOLTAGES or check your settings, although it's more of a voltage problem most of the times.

If your CPU is stable you can OC your memory and uncore.

Remember: if you overclock it's better if you change only one variable.

Which means, raise only one sort of voltage at once, so if your OC doesn't appear to be stable then you know which voltage to raise.

Small remark: x12 uncore was never stable on both my UD3R and my UD5. x13 worked fine.
