Do i just have a bad chip? i5 760

post #1 of 10
Thread Starter 
Hi all,

I'm really confused here.
I have i5 760 with asus p7p55d-e pro.
I currently have my cpu at 3.8ghz (200x19) with 1.287vore (bios) and 1.225 Imc and is stable. I was messing around today to get to 4.0ghz and it just would not hold stable at watever voltage.

I even tried 191x21 with LLC enabled with 1.356 vcore and it still fails Linx.
I tried upping Imc to 1.3 to 1.35 range and still fails. To my understanding running lower bclk=lowever voltage required. In addition my ram is still running at same speed at rated clock @9-9-9-24 1600mhz. If i'm able to get my ram stable at this setting shouldn't I not even need to touch imc for that matter? as im only running 2 sticks of 2gb module at its rated speed

I just dont understand. I'm able to reach 3.8ghz (200x19) with these settings and even 5 or 6 notch increase in vcore is still not stable enough for 4.0ghz. It's not like i raised the blck just upped the multiplier 1 and why does it require so much increase in vcore...

is my chip just crippled?

On my old i5 750, it took 1.375v for 4.0. Some chips you just can't push as high. Are you blue screening when stress testing, any error codes? You can try running your memory at a lower speed also, you won't notice much difference from 1600 to 1333 and that may be what it takes to get you stable.

i can't even make 5 passes of linx.
it bsod 124 after 1 or 2 by pass.
i mean i understand if my chip required high voltage to start with but its stock voltage is 1.185 no overclocking under full load.
I'm able to reach 3.6gzh at 1.206vcore and 3.8 at 1.2875 which is not great but acceptable but requiring over 1.35volts for 4.0ghz just seems ridiculous to me

It probably wont pass stress testing but normal use you wont have any problems. Same thing with my i5 750 it doesnt like stress testing but have 2 games open browsers tabbed out streaming music downloading and it humms along no problems. You could probably run that chip somewhere around my same specs with no problem

Which bios version are you using on that Asus P7P55D-E PRO board?

This BSOD code list should help you with getting your i5 stable.

0x101 = increase vcore
0x124 = increase/decrease QPI/VTT first, if not increase/decrease vcore...have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1A = Memory management error. It usually means a bad stick of Ram. Test with Memtest or whatever you prefer. Try raising your Ram voltage
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

124 code needs more vcore or QPI/VTT to go away.
If your cooling allows it, I don't see the problem in pushing the vcore higher. You're far from 1.45v anyway. Might be a big difference from 3.8 to 4Ghz (in vcore that is) but so what. Not that big of a deal.

im running bios 1602.

Are all power saving options off in the BIOS ?

yes it is. dont get me wrong, i can pass prime 95 for hours with lower volts like 1.33 something then when i run ibt, linx occt it just bsod. Maybe i'll just leave my vcore at 1.33, since i will never ever put my cpu at that kinda load like linx does..
