so im playing with psc for now and getting a feel. i have yet to see 2800 on the mems out of ivybridge :shakes:
on the other hand... i have booted 2600 7-12-7-27 :wasntme:
stability is a real struggle with c7 2600 on air. mabye i should try using a better fan. the dominator airflow fan might not be cutting it.
I think you need extreme cold for them timings... air won't cut it, unless you are in Antartica..
i dont think extreme cold is the answer, just more cold. i live in los angeles, if i could get 0-5c ambient... ever, i bet it could do it. as it stands now i have central a/c so i cant ever get the room below 18c.
I use a 12000btu window unit, my wife hates it, but the air comming from the unit is 6c. You can take the temperature sensor out and wrap it with insulation to prevent it from getting cold and telling the compressor to turn off, keeping the room extremely cool . You can get a decent one for around 300.00 at most places.Quote:

Still trying, spent way too much time trying to figure this out. Testing all the ram I have, and this is the best time so far.Quote:

tRCD and CAS at that frequency possibly best time 6m20-21. As for the tRAS, it will be 22 clocks before the burst is made, the page cannot be closed until the row and column is latched, so going any tighter than that will simply force the chipset to issue a minimum spacing. 24-26 is the fastest internal timing that is possible.

Guess I wasted a lot of time trying that lol.
This is where Im at now.
tFAW 16, tRRD 4, tRTP 4 will shave a bit more time if you can do it. Don't focus too much on the tRAS :)
Thanks for the help Raja! I was trying anything to lower the time, thats about the best it I can do with the memory I have to work with. Spent a small fortune buying different kits, this happened to be the first cheap 2133 GSkill ripjawsz kit I bought for x79.Quote:

Been having a hell of a time with this so far, ram clocking is kicking my ass.

Best I seem to be able to do. Can't get turbo to work with my usual 32M OS and can't seem to match it. Also can't come close to the mem clocks around here, probably doing something dumb.
I needed to enable PLL overvoltage in order to post at higher than 2400 divider (2600/2666).
I was struggling and wondering why none of my mem kits don't even post at 2600. Don't know if that's logical (I'm an AMD guy), but seems to work for me.

*reminder: please follow format girls
@infrared
enable pll overvoltage was necessary to go beyond 4.8ghz[on the sandy days]. msi bios actually enables pll overvoltage if it goes past 4.6ghz[i think] which is a neat feature.
Yeah, I know about sandy, but kept it manually disabled for Ivy while at 5GHz, because it didn't make a difference for the cpu clock. And I haven't tested it with LN2 yet.
This was the key for POST-ing at 2600 memory, but I don't know if there's something other that is wrong with my settings.
The thing is I treid various vccsa, vccio, pch, vdimm voltages and stupidly slack timings, but nothing helped, except enabling PLL. It's on auto by default on MVG and the board enables/disables it when needed.
Don't know what is the threshold. It might be connected to some other settings, I don't know :).
I might sound like a noob, but that's what I am actually :D
Learning is good. I'm Amd's grand master noob lol.
Well I've been having problems with memory clockings also with MSI Z77A-GD65. I can run 1200 8-10-8, but anything above that is really really hard, or impossible. I have 4 BBSE sticks and 4 PSC, none wont work at 2500 no matter what latency, but on 1200 @ 1.85v BBSE I can run with this settings LINK and I get 6:22.7xx, but there is a lot more in it
Tested with both 3770k, exact same behavior. On M5G, they can boot 2933 with Samsung lp memory
tested some trident bbse on ln2 -150c but going to need more vDIMM to get anything like this to pass, fails loop @ loop 4 consistently...tRAS has been on biotch on all my trident kits... not much better than air timings would pass.... was still fun though :up: looking forward to 2.3v on MVF when released

Verry nice Splave, pic of you setup ?
How much Vdimm ?
Here's my 1st go trying to do a wazza!!!
C-N - 6:22:781 - 50x100 - 1200MHz - 8-10-7-22-68-1 - Gigabyte UD5H - GSkill C8 2133mhz 2x2GB/BBSE - 1.82v - Stock Air

You need to enable maxmem = ~600 MB and LSC first before doing waza, I don't think it really helps with 2GB+ ram available...the goal is to get all of the running processes out of the ram if I understand correctly.
his LSC is already running but he should try maxmem like you said
Thanks for the tip :up: I did sort of try that but couldn't see any benefit although I'm not done yet :) That run was just server 2003 as is, real time & affanity & a copy.Quote:

thats a good run c-n. thats about what a 3770k will do w/ 2400 8-11-7-27 1T. if 3750k is anything like 2500k, its a full second slower when compared to 3770k just because of cache.
Thanks Zen. I was thinking up to about a second as Splave commented on here one of his runs was 6m23.500 ish without wazza & my 3570K runs 6m24.500 with the same timinge etc. The only difference was Asus v Gigabyte.Quote:
