Ram compatibility issues help please

addbacon · Feb 17, 2016

so basically i didn't do any back round checks on the compatibility of my ram and i just added another 16 gigs of 2400MHz so now that i have 32 total my computer randomly freezes when i'm gaming sometimes and it will show error code 02 AP initialization before microcode loading so i hit memok and it was running fine then did it again now when it crashes it shows 04 PCH initialization before microcode loading so the mobo's booklet doesn't show my corsair ram under capability list for 2400 but shows it in 2133 and 2666 so do i have to get rid of it and get one of those? also i am pretty sure it did not crash at all when i had 16 installed. what would be a better set of ram over all or is there anything i can do to fix this problem or did i just waste my money?

Try raising the DRAM voltage + 0.05 and the DRAM VTT voltage up + 0.075

addbacon · Feb 18, 2016

Ok, i'm in my bios right now but i can't seem to find where to increase the voltage.i do see DRAM current capability (sets the shut-off current limit for the external DRAM voltage regulator. Its set at 100% and can be set in 110% 120% and 130%.... ok i found it but its all set on auto and im not sure how to manually adjust it

Tradesman1 · Feb 18, 2016

Click on where it says Auto, use the + or - keys

addbacon · Feb 18, 2016

Ok i believe i did it correctly thanks so much for helping me, now im going to run a game and see if it crashes at some point and let you know. Also if this works is it better to have the ram running at 2133mhz or 2400mhz ?

Tradesman1 · Feb 18, 2016

2400 as long as it's stable

addbacon · Feb 19, 2016

ok, it hasnt crashed since then so thank you i think that did it

. if i adjust it to 2400 will that voltage be fine as well? also 2 more questions. should i be running xmp profiles ? and in your opinion is there a better set of ram for my build you would have chosen over what i have?

I lean towards GSkill DRAM, generally stronger (OC headroom) and not paying extra for the name. I've got the 6600K and am currently using their TridentZ sticks, their Ripjaws V are right up there with the Zs. If thinking of changing the 2800-3000-3200 area looks best from a price to performance standpoint (might need a bit of a CPU OC to run to full data rate) . They have new models in all three data rates with a tight CL 14

addbacon · Feb 19, 2016

awesome, thank you again for the information!

Tradesman1 · Feb 19, 2016

No worries

addbacon · Feb 20, 2016

crashed at 2400 eventually, im gonna run it at 2133 for a longer period and see if it works

Tradesman1 · Feb 20, 2016

Keep me updated

addbacon · Feb 21, 2016

screen went black no error code so i restarted and it gave me a message overclocking failed enter setup to reconfigure system, i went into bios and it was all set back to original settings. i turned on xmp profile and am trying again

addbacon · Feb 22, 2016

froze again with error code 02 trying xmp profile but at 2133 this time

addbacon · Feb 23, 2016

froze again took out tried back to original settings with only 16 gigs.... seems fine so far, i have no idea what the issue is

Tradesman1 · Feb 23, 2016

Might be the two sets just don't want to play, generally those voltage adjustments can help/ get them to play, but not always, that's why always best to get full amount in a single package rather than mix sets, which offers no guarantees

addbacon · Feb 23, 2016

hmm so pretty much am i screwed? or is there anything else to try

Tradesman1 · Feb 23, 2016

If the sets don't want to play, I can normally get set to play, but have run into some pairs of identical model sticks that just refused. It's why I recommend all in a single set.

addbacon · Feb 23, 2016

indeed i hear ya. have we gone through everything there is to get em to go? it shall be a shame to see them not in use for the price

but i do understand

Tradesman1 · Feb 23, 2016

Might try changing the timings manually from 14-16-16-31 to 15-16-16-31

addbacon · Feb 23, 2016

ok i will give it a shot

addbacon · Mar 3, 2016

it did not work, but i now have 2 questions could the cable from my cpu fan touching the ram cause any problems? and i just realized i have windows 7 home premium it can only use 16 gigs?

Tradesman1 · Mar 3, 2016

The cable shouldn't bother anything, no. Win7 HP yes, max is 16GB as you indicate

addbacon · Mar 23, 2016

ok so crashed even running 16 gigs in xmp ummm should i just get rid of this ram or could it be my power supply i want to get the right ram for my system

Tradesman1 · Mar 23, 2016

Might just be the sets don't want to play...it happens, might look at a 2x16set, GSkill has their Ripjaws V and TridentZ in 2800-3000 and 3200 all available with CL14 (I grabbed the TriZ in 3200/14 2x16GB and they are great on my Hero
