kevindd992002 are they in the board supported list? Are you running the latest bios? Try to add the timings and voltage manually in the bios and see if it boots

I doubt they are in that qvl list...being older psc ram.

Sounds like you got a too high value for LLC and it might make your vcore overshoot. You should have 0 llc for offsets and llc enabled for fixed vcore. With 0 llc in offset mode your idle vcore will be low but not too low as to cause instability and your load vcore will droop a bit, but if you have a high enough offset you can compensate it.

In my motherboard there are 5 LLC settings, levels 1 through 5. Level 1 is the highest compensation,Level 5 being the lowest. No matter what I try (I've tried 3 BIOS') it's always stuck on LLC 1 , the highest compensation.

My system is perfectly stable atm, that's not the problem. I mean, yes, it's a pain where the sun don't shine, but the main problem is the varying voltage. Is that due to LLC?

I was previously using fixed mode ( No problem running 100% load all the time) but someone told me that the LLC levels didn't work with fixed, only offset

If all goes as planned I will probably take 8 gigs of my miracle ram and throw it in that box, and leave my sig rig with the remaining 8.

The RAM overclocks great on my board, as the GPU. I have full faith that the CPU would do the same. I'm currently not limited by temps or volts, just the stupid fluctuating voltage. ASRock approved my RMA but I'd really rather just fix the issue, since I don't know if it's an isolated issue or common to all boards

You ran memtest86+ or hci memtest overnight? regular memtest86+ doesn't work for stability once oced, only to check for errors at stock clocks.

Ok. Running stock clocks would mean setting everything concerned about the CPU to Auto, right?

I ran HCI Memtest overnight, not memtest86+. What program do you use to check stability once oc'ed?

Nope, not on the QVL list but these RAM modules are known to be very compatible with my board, at least that's what was recommended to me in the past. I can boot with the settings I just mentioned above, just not stable with hci design memtest.

LLC should work without offsets, stuck at 1 means it's a faulty board (cause like you said you tried different bios versions without luck). LLC 1 is the culprit of the higher vcore under load, so rma it and try with a new board. It ain't good to pump more vcore under load, not really needed.

Cool then, run cpu at stock and try to oc them. You can either test with hci memtest or IBT max memory for 5 passes and superpi 32m for quicker stability testing.
11-11-11-30 is ridiculously loose for PSC ram, the looser I'd go is 9-11-9-27-2t really.
If you're not using more than 4gb ram you can cut down to 2x2gb really. That's what I run and have no problems whatsoever for benching, folding and gaming.

Ok then. How many percent coverage should I aim for ultimate stability with hci memtest?

Yeah, I know those are super loose. I'm just trying those timings to see that I have no problems whatsoever. I can be 100% sure that my RAM modules have PSC chips, right?

I actually need 8GB. Using a lot of tabs in Firefox, my usual RAM usage is around 4GB already so I have no choice. But either way, populating all 4 DIMM slots should still make my overclock good with these kits, right?

I have heard reports of trouble getting to 2133 and above on Asrock Z77 boards though have yet to try on mine. I hope I am mistaken and that there isn't indeed a bad pattern there. I am presently at 2000 1.35v.

I'm interested in the memory, but Is there a certain model that is the best to get? I want to get 16GB. But I have to start off at 8GB (2x4GB) first, then add on later.

This model any good? And is it better to get the kit or single

2x4GB

1x4GB

4 sticks with your weak imc will hinder the oc...if I were you I'd settle with 1866mhz cl8-10-8-27-2t with 1.7v. That should easily work.
