Small FFTs19 hours of Prime 95 no errors. But on Blend and LinX errors

[matvey]

i ran 19 hours of prime on small FFTs didn't get any errors but on Blend and LinX having a problems, looks like it is a RAM issue > what should i raise VTT or DIMM voltage. thank you

Yep its a RAM issue for sure ....I would maybe up the RAM volts a touch...or loosen up the timings a bit....Run memtest86 and see if you mem mods are good or bad...it may just be a bad set of RAM

i tested the RAM on Memtest86 everything was good. so maybe i should try to raise DIMM to 1.75?

No do not raise the DIMM voltage that high....DDR3 is usually limited to 1.65v no more...you will cook them mem sticks with 1.75v.....I would loosen the timings or lower the clockspeeds of the DIMMs........again DO NOT USE 1.75V ON THOSE STICKS

when i pot everything on auto my motherboard gives 1.7v on my RAM, should i try 1.65 V 7-8-7-20? what do you think?

 

[lowjack989]

I would put the RAM to mfg. specs and forget about what the MOBO does...I have a suspicion that the RAM being set by the MOBO is causing this RAM instability issue. Yeah 1.65v @ 7-8-7-20...is better than that 1.7v setting

 

[matvey]

thank a lot, gonna try that. you think that raising VTT will not going to help?

 

[lowjack989]

No raising the VTT voltage wouldn't help the RAM become stable...only the DRAM voltage, clockspeeds, and timings...effect the RAM stability...with regards to all other settings being stable

It's not the risk of cooking the RAM that you need to worry about. You need to worry about frying the memory controller that lives inside the CPU.

Good Point, I just thought that the sticks would be the weak link that broke first in upping the DRAM voltage...I guess, I thought wrong though ...Thank you, for the correction

guys it was not memory problem, it is CPU, i was getting BSOD with code 0000000...124 and 000000... 101
which saying to raise a Vcore, and thats what i did i raise a Vcore just a little bit and now everything is good.
