Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 96

post #951 of 4581
I thought my OC was stable. I'm getting random BSOD's when playing games

It passed 10 runs of Intel Burn Test @ Very High stress level. It passed 10 loops of x264 Stability Test v2.

I'm gonna reduce the DRAM speed to 1,333 MHz and play more games to see what is the problem

It looks like the IMC is weak.

doubt the imc is weak on haswell, for <2133mhz thumb.gif

do you get rounding errors in prime95 blend? I just found out I get these errors even at everything stock frown.gif I get some errors in memtest too so its probably the ram, hope its not the imc since I delided already @@

This has happened to me before, but only due to the fact that the motherboard was not feeding the correct voltage to the RAM

Sometimes certain sticks of ram need 1.5+ volts even though their rated for Reference...

I had gigabyte easytune installed with the MOBO drivers so i tried playing around with its preset OC settings but those didn't work either. I finally was able to get results in the advanced OC settings tab on easytune where i manually adjusted the multiplier and voltage myself. I am set at 4.3ghz and 1.224V at the moment with no problems at all.

I did notice the clock speed on cpu-z always shows 4.3 even when idle even though it would drop down when idle before the OC and only show max when doing a stress test on prime95. Should I be alarmed at this or no?

thanks.

Read the Z97 overclocking guide of Sin0822. Do it yesterday.

Been doing 3000M custom blends to test out settings with my 4gb 1600 1.5v ram:

VDIMM / VCCSA / VCCIOD
1.5 / 0.83 / 1.08 (stock) fails <10min
1.65 / 0.83 / 1.08 fails <10min
1.5 / +0.3 / auto fails <20min
1.65 / +0.3 / auto fails <20min
1.5 / +0.3 / +.15 fails <20min
1.65 / +0.3 / +.15 fails <20min
1.5 / stock / +.2 fails <40min
1.65 / stock / +.2 fails after 4 hours headscratch.gifwheee.gif

Does this mean... my ram needs a voltage bump... but in order for that to work.. my cpu also needs an IO voltage bump... but my bios doesn't automatically bump the voltage which is why I keep getting rounding errors ?????????? teaching.gif

Hmm that is weird, what ram sticks have you got?

i just have 1 1600 stick cheapo cl11 rated 1.5v, dont really want to rma it cuz i wont have a computer lol, maybe ill buy another stick and rma this one to get dual channel, but dont really need 8gb.

the last setting seems close to stable, only 1 worker failed afte 4h and the other was still going after 12h, just did 1h occt linpack no errors, im guessing vcciod is best at around .5 to vdimm, just that my ram is not stable at 1.5v

Have you tried underclocking them a little bit, I know you wouldn't want to but I suppose it's worth a shot.
Perhaps you can try 1333mhz and perhaps somewhere between that and 1600MHz.

If it's a fault with your ram your best choice would likely to be RMA.
post #960 of 4581
I tried 1333 with the same timings as 1600 but it seems to make very little/no difference, actually I wouldn't mind underclock if it makes it stable bigeyedsmiley.png, I swear this ram is making me dumber xD Anyway I'll probably rma it eventually when its more convenient. Now that its kind of stable back to overclocking wheee.gif
