Why can't you run a voltage of like 1.8, 1.9, 1.95v, for a 24/7 overclock? Your temps on air would be fine and under the max of 90*C, and the max voltage for ram i hear is like 1.9v at lowest. And since ram is so cheap, who cares if it degrades slightly because you ran 1.9v? Right? I mean I find PSC XDZ ram that does 2400mhz CL8 for $25 2x2gb regularly, I see samsung miracle ram, that's only $40-50 right, avexir has some 200mhz CL9 2x2gb for like $35, i mean you can get high performing ram for quite cheap, it's not like blowing out an ivy bridge or something.
Can you please post where you can find 2400 c8 PSC for $25 2x2GB regularly? I am pretty sure my quad channel 2400 c8 kit costs exponentially more than that:p
the 30nm Samsung stuff is meh, 2400 c11 is about all you are going to get, if you want highly binned HYK0 the G.Skill 2666 c10 is your best bet.
The Avexir dimms you are speaking of are BBSE?
One thing to keep in mind is that an Ivy cpu can be replaced, once your PSC is dead you are not going to be getting another kit with the same ic's so it is much harder to replace.
Ebay, OCN trading forum, any trading forum. The hard part is knowing what RAM is PSC, since it isn't exactly advertised and there's no lists anywhere, you just have to find some post where maybe some guy on some russian overclock forum says "russian russian 996902 russian russian PSC". There are tons of PSCs being sold for $20-30, actively, you just don't know they are PSC. A lot of PSCs are sold with very bland timings like 1600mhz CL9-9-9-24 so you wouldn't know it was PSC unless you look up the exact model.
Also, this sort of ram only exists in 2gb sticks (PSC or BBSE, both only made in 2gb density as they stopped existing as such entities long ago). You are basically buying like 3-5 year old ram, just most people don't know what this ram really is, it's going to be used, it isn't supported anymore, so they go cheap.
I can say for certainty that any mushkin that has speeds of 2000mhz CL7-10-8-27 or 1600mhz CL6-8-6-24 is PSC XDZ (there are redlines, radioactives, blacklines, and ridgebacks of both of these timings). I know right now on ebay there's 3x2gb mushkins radioactive 1600 CL6 PSCs going for $69 OBO, meaning it'll likely sell for around $35-50. That listing is a bit expensive but there's ton of PSCs being sold, you just have to figure out what ram is PSC. It's definitely time consuming, but if you put the time and effort and research into it, you too can get yourself a hold of RAM that can do 2200mhz+ with tight timings for under $30 per 4gb.
Buying 4gb density sticks of speeds over 1866mhz is prohibitively expensive, and even 2gb sticks rated at 2000mhz+ are going to generally be expensive. PSCs are a great buy because they overclock so well, so they might be sold at only 1600mhz, but you know they can do 2200mhz+. The avexirs are BBSE and those are like $35 on amazon or ebay or somewhere, 2000 CL9.
So I just got my 2nd PSC kit to get 4x2gb of ram, and I'm having a lot of trouble making it work. Furthermore, my z77x-ud5h isn't letting me change timings just on one channel (i have my ram like A/B/A/B, where a is my 996902 that i've had, and B is the new ram), I can't seem to get timings to stick if i try to set each channel to different timings.
And, i think my SSD got corrupted or something from all the resets over and over. I"m not sure what's going on, I only know that the same error i'm getting now, is what I had when I tried to boot from a HDD when the sata connector was plugged in the opposite way (someone broke off the plastic support). I have No GUI boot option, so at the normal w7 splash screen, I get like 8 blue dashes at the top right of my screen. Well now, i get the dashes, then a second later, i get like a polychromatic line stragith across the top of my screen and it's just stuck there.
I was thinking of throwing the ssd into my laptop, see what happens, but I'm wondering if I shouldn't even bother. I took out the new ram to see if the ram was causing it, took out the old ram and tried just the new ram....
like obviously something isn't stable but im not sure where to really start, because my overclock was so fine tuned. My vtt and imc and pll all being below stock, my timings, i mean i wasn't having much luck but now this.
On a side note, i checked the RAM IC of 996826s that i got, it's XDZ015A3G-A, which means they were made 1 week ahead of my 996902s lol (xdz014a3g-a). I
