QPI / VTT - I can't imagine that you would need more than 1.35v for DDR3 1600Mhz speeds, regardless of capacity. I only used higher than that when getting 12Gb of DDR3 2000 memory up and running stable (ASRock X58 Extreme / Asus P6X58D-Premium / MSI X58 Big Bang). I didn't realize that you were already running your memory at 1.65v, so not sure I'd bump it all the way to 1.70v to start with. I'm allowing for a little voltage droop so maybe tack on the next increment that your BIOS allows - .02 etc. if you have that level of granularity. Additionally, even though your BIOS appears to be setting your 4 primary timings OK, I would go ahead and manually input the primary timings (the slowest of the two kits as mentioned above) and I see that you are running 1T (1N) timing. Change that to 2N.

Yeah I was thinking of doing that next, I won't ever push these past a memory kit's stock speed specs.

 

$10 says changing the 1T rate to 2T will solve nearly everything. I've given up on running 1T with half full banks or more.

I'm pretty sure I had manually set them to 2T before but I'll definitely assign all the manual settings I know of.

 

Yeah but at those speeds i was using 1.55 and even 1.6 QPI to run at those speeds and timings... Point is for X58 QPI voltage is extremely important for 6 sticks or high speeds... Or both... Lol.

damn :blink: , I'll keep that in mind but hopefully I won't have to go THAT high!

 

Complaining that it will not run on Auto settings is akin to attempting to drive a car then wondering why it wont start because you do not turn the key. I have needed upwards of 1.5v QPI depending on the speed and timings of the kit I have tested. You will need to manually tweak your settings to improve compatibility. :mfp:

Oh yeah I know, I just threw them in auto since CL8 and it's following set latencies I was running with the OCZ's alone obviously wouldn't work :P. I'll go set them to manual spec now, great to know that 1.35v isn't the stopping point QPI has been run by alot of you.

 

I was having these same problems on my x58 board. I just decided to run 12GB of memory and leave it at that. I read a lot about mixed ram is just a horrible idea on X58. It had something to do with a bad memory controller because the intel people never truly perfected the triple channel memory.

 

Honestly, the best thing you could do is see if you can sell off the 6Gb of memory and buy another 12GB of ram. I would do that quickly too because if you don't, you could miss the opportunity to buy the same stepping as your 12GB kit, and then it would be back to square one......trust me.

It's definitely something I'll consider if I can't stabilize these as they still fetch a decent used price.

 

You might. :lol: RAM is RAM to me, I just buy what I need and tweak the timings to get it to run properly if it gives me trouble. The trouble part doesn't happen very often, but I gave up on running 1T timing rates back when I was still running regular DDR. I haven't touched a board or cpu capable of running multiple sticks at 1T since the switch to DDR2.

:withstupid: The cheapest sticks get my money, and I've never had an issue, this is clearly a memory controller issue. Usually it autos to 2T, CPU-Z shows it at 2T now but I'm going to go force it anyway.

 

Just picked up a set of mushkin 2x4gb 7-7-7-24 t1 for my new build, this will be my 7th set of mushkin ram

 

3 sets of 3x2gb 6-8-6-24 t1 1.65v x58 system

1 set of 2x4gb 9-9-9-24 t1 1.5v used in a family build

1 set of 2x4gb 7-8-7-24 t1 1.65v used in primary rig

1 set of 2x4gb 9-9-9-24 t1 1.35v used in secondary rig

1 set of 2x4gb 7-7-7-24 t1 1.5v used for my new mini itx build

 

i guess im just luck but all of the m auto config and work as soon as you plug them in with no tweeking unless i overclock them

I often run auto, or at least past the known stock specs and haven't had any problems with the Corsairs (had to RMA one kit of DDR2 sticks but that's the only memory I ever had to send in), GEILs, OCZ, Patriot, Kingston, Super Talent, Gskill, Samsung, Hynix, Panreema (I think that's what it was called, some ebay cheapo brand I bought to add 1GB to an old DDR1 machine) and there might be others I'm forgetting.

 

I have had good luck with just about every manufacturers stuff. Some better than others and it really came down to consistency and long term performance

Pretty much, except I got an unstable set from Super Talent but they had weird specs. They were 800mhz @ 4-4-3-8 timings, DDR2 of course. I could never stabilize them at that but they ran fine at 4-4-4-12 (a more common lower latency 800mhz setting) and I sold them eventually and never got any calls with death threats lol.

IVI - in the BIOS screenie you took of the AI Tweaker menu > 2ND Information (memory timing Info) - it clearly shows that it is running 1N doesn't it?

Yeah, I must have been thinking of when I ran my OCZ's then. I changed the settings manually and the ram is reading 16GB :glare: with 1.66v on memory....gonna start working up QPI I guess...

 

Oh and something odd and possibly related, my Vertex keeps switching from having like 2-3GB left on it to like over 10GB-15GB free... I'm so confused

Hopefully you'll get everything tweaked to the point that all of your memory will show up and you can get a good overnight run of Memtest in without any errors. Good luck.

Dont get me wrong I've used my fare share of ram to Ultra, Viking, Samsung, Corsair, OCZ, Geil (given to me by my brother), Gskill, then hit Mushkin won two sets 3x2gb from a 3dmark06 contest here and have never looked back. I still have a few systems running some gskill and corsair ram but untill some mushkin ram treats me wrong im going to be a diehard fan. I use to love Gskill, have two systems running on them but once i hit the x58 board they didnt work. The board would randomly see different amounts with matching sets. i would just reboot till it saw all 12gb then never turn my computer off. I'm was not as patient as you are to tweek them into working.

 

Edit: going back through my photobucket album and ran across a few screenshots of my bios

 

Ram 1854mhz 7-9-7-24 t1

PLL voltage 1.86825

QPI voltage 1.33750

Dram foltage 1.69600

IOH voltage 1.35150

Thanks, I hope so too, it's so close to being stable.

Hmm I'll try bumping the IOH as mine has more to go but all your other voltages are surprisingly low, thanks.

I took the QPI to 1.4v and IOH to 1.32v and still nothing, I decided to drop the multi to 20x (4.0ghz) and it's stable even with me taking the QPI down two notches to around 1.375v and IOH to 1.3v...though it's only reporting 16GB :glare: This is fine for now, if it wants to randomly hop in and out of 16-18GB it can be my guest but atleast I have most of my memory working and my overclock (since I think 4.2ghz was never fully stable...must be the fact that this chip shouldn't technically have a 21x multiplier lol). Oh and my RAM is at 1.7v just in case they were undervolted some.
