Question on add-on memory compatibility.
 
I got my system in March, and have been very pleased as it continues to be an excellent contributor to (among other things) Stanford's Folding at Home (which, by the way, is worthy, IMHO, of consideration by any of us who have spare cycles to contribute to support molecular dynamics computation in a massive distributed computing environment - http://folding.stanford.edu/English/WinGuide; http://folding.stanford.edu/English/Main)
 
I saw at [a local computer store] a July 4th sale on 8 GByte (2x4GB) of Corsair XMS3 Dual Channel 1600 MHz memory at a good price with rebate. As much as I could tell, this would be compabible with my system.
 
Below is a screen-snip of the ASUS AI Suite, CPU-Z for the CPU, Mem slot 1 and slot 2, along with the Cyberpower gadget in the upper right corner showing power consumption (less the monitor which is on a different ups). All of the memory is recognized - showing 12,268 MB. The BIOS and CPU-Z all see it in the SPD sections.
 
The issue: After I initially installed the memory, the system would power itself off after a minute or two and reboot. Over the next half hour or so, it did it several more times. I adjusted the overclock to the point where it now seems stable.
  • I started out with the system clocked at ~4539 MHz (103x44), where it had been completely stable for a couple of weeks of 24x7 high intensity activity.
  • My "stable point" with the new memory seems to be now at 4200 MHz (100x42). It's been up for an hour now with no hiccup, while using 7 full threads for Folding at Home Symmetric Multi-Processing workunits, running the GTX 560Ti GPU at 99% GPU utilization on the specialized GPU work units, and running IE9 for this, along with all the monitoring tools shown in the screen-snip.
 
  • The total of 8 GB of corsair memory in Slots 1 and 3 are showing in CPUz and the ASUS AI Suite/UEFI Bios a tRC of 41, and a command rate 2T.
  • The total of 4 GB of "Digital Storm Certified" memory (actually Adata) shows the tRC of 33 and no Command Rate.
 
After the long wind-up here's the question.
a. Is there an issue with this mix?
b. Is there a way to command the tRC in the bios of the Corsair memory to match the Adata? Is that necessary/beneficial?
c. Is there anything obvious with the Corsair memory or its settings that make it unstable at 103x44 (4539 MHz), but stable at 100x42 (4200 MHz)? I would really like to get the OC higher - back up to the 4500 or 4600 MHz range.
 
Thanks.

Update. The system power cycled itself after about 2+ hours on the 4200 MHz setting - I changed the OC setting once again to 100.3x41 - about 4100 MHz, and it's been up 4 hours 24 minutes at full load.

u should never mismatch ram. At the very least you would want to run them both at the same exact settings so the faster ram would be limited to the slower rams speed.

also your b-clock with sandy bridge should always remain at 100, that could of been an issue. I would need to look at all of ur oC settings to give you some more guidance.

@ RiceEatin2000GT- Thanks for the comments.  All 12 GB of memory (the orginal 2x2 GB A-Data from DS, and the add-on 2x4 GB Corsair I just added) seem to be quite stable now - I'll post some memtest results later.

My next step after the post above was to go back into the EUFI BIOS and put the OC settings on Auto. That seemed to be the magic trick. I took a finer look at the "official ASUS P8P67 Overclocking Guide", and saw the little blurb about running 4 dimm and high memory density configs. The 103 BClock suggested in the [H]ard|Forum article on 24-7 OC must have been without all the memory slots occupied.
 
So, the steps I took in auto were:
 
41 multiplier - BIOS auto selected 100.3 Bclock. Stable.
 
44 multiplier - BIOS auto selected 100.3 BClock. Stable for a couple of days at 24/7 Folding. 1.368 Vcore; 324 watts. 66° C CPU when MB temp was 33° C.
 
46 multiplier - BIOS auto selected 100 BClock. ~ 4600 MHz. Stable for 2 3/4 hours so far of folding - No apparent gliches.
  • CPU running about 74-75° C with MB temp at 36° C under 88% CPU load - fans all 100%
  •  (in Folding at Home, virtually no difference with using all 8 hyperthreading threads and 7 WRT power - using 7 threads fully occupies the 4th core's floating point unit)
  • Power consumption with 12 GB memory, 4.6 GHZ OC, and GTX 560 Ti at 100% GPU load toggles between 333 and 342 watts per the Cyberpower UPS monitor.
  • The BClock seems to jump around between 99.1 and 100.2, with most of the time at 100.0. This, I guess, is driven by the Auto mode. With a fixed multiplier, the CPU frequency follows.
  • Vcore - 1.416 (when I was running with only 4 GB memory at 103x45=4635, the Vcore was 1.476).
I'll go to bed and see how it is doing in the morning.

Lastly when considering adjustments to the BLCK range, it is important to remember it will affect the memory divider/strap and DRAM frequency. Keeping this in mind you may want to adjust to a lower divider if your memory does not higher frequencies. This especially true when attempting to sustain 4 dimm and high memory density configurations with high BCLK and high Turbo Multiplier values.

i would keep the bclk at 100 no matter what imo. Your settings look good just keep an eye on your v-core when using auto. Typically any multi from 44-47 should require 1.3-1.375 v-core. This also requires the proper line load calibration settings of course.

@RiceEatin2000GT. I appreciate your reviewing and commenting on my travails.
I had a couple of more auto shutdowns. I was stable with the mixed kinds of memory for days at 4400, when I tried to goose it up a bit more.
You mentioned, "This also requires the proper line load calibration settings of course."
 
Please advise what is the proper setting. Below is a snip of the DIGI+VRM page of the AI Suite II, as well as the TurboV  EVO with both the CPU and Sensor monitors..
 
Many thanks.
 
BTW, I guess one remedy is to get rid of the mixed memory - the 2x2 GB DS-standard A-DATA Gaming memory, and the 2x4 GB Corsair XMS3 Dual Channel 1600 memory. A-DATA doesn't seem to have 4 GB sticks in the same series of Gaming memory as Digital Storm installed, nor does Digital Storm have ANY 4 gig sticks in their upgrade center. Question - do you think I need to abandon the original memory in favor of the higher capacity Corsair, or do you know of a way with the Digital Storm 2x4 Adata memory to get up to 12 GB?
 
========================
In the DIGI+ VRM, there are a bunch of settings - a slider on the load-line calibration (set at its nominal HIGH - but the slider will go quite a bit more to the right); Current capacity set to 100%. In the last round in the BIOS, I set the DIGI+VRM from Auto Spread-spectrum OFF to ON, where it is now.

First thing i see that could be potentially wrong is your ram voltage. I do all my tweaking through the bios so if we could do that so i can help you the best that would be cool. Link me to the ram you bought? it seems like your voltage for it is at 1.5v. Thats more than likely to low for the ram that DS put in your computer along with what you bought. Typically 1600mhz ram is 1.65V unless its some low voltage stuff.

Thanks for the note.
 
 
This is the memory.
 
It, indeed, is rated for 1.65v, as is the Digital Storm A-Data memory.
 
Current status - I'm 17.9 hours up on the 4400 MHz config I posted last night. Running relatively cool (67º C), although I might give my case fans a tweak.
 
I think I set the AI Tweaker in the bios to the  "XMP" setting. "If you install memory modules supportint the eXtreme Memory Profile (X.M.P.) Technology, choose this item to set the profiles supported by your memory modules for optimizing the system performance." I don't think I manually set the 1.5v.
 
I did just reset the DDR voltage shown in the snip above to 1.65v it in the Windows AI suite - no apparant hiccup. But, of course, it's been stable for almost 18 hours at nearly full load (89% CPU, 99% GPU, 324 watts) at the 1.5v setting - so I'll see if that continues to be stable.
 
I'd like to see if I could find a setting that would let me be stable at 4.5 GHz - do you have a suggestion on the load-line calibration?
 
Again, thanks.
 
 
 
 
==================================
Additional working: case fan config.
(currently - HAF922 - top and front 200 mm fans blowing in; side 200 mm fan blowing out; back 120 mm fan blowing out. System came with side fan also blowing in per discussion with DS techs to keep a good positive pressure in case - but when I started OC, I got better temps by reversing side fan to blow out. I may reverse top and side so front & side blow in, top and back blow out).

at 4.5ghz i would start with this

obviously multi at 45 with 100 bclk
v-core- 1.35v
Line load calibration of very high
vrm frequency of 350
phase control set to extreme

This should be enough to get you stable for 4.5ghz.

I think the normal fan setup for the HAF 922 would be the front and side blowing in and the back and top blowing out.

Thanks for all the prior advice. Have a quick memory configuration follow up.
 
As I posted before, I have 2X2 GB Adata 1600, the original Digital Storm "certified memory". These were installed, per ASUS instructions for the p8p67 Deluxe mobo, in memory slots A2 and B2, or as depicted in CPU-Z in slots 2 and 4.
 
I then added 2x4 Corsair 1600 memory in the two open slots - A1 and B1 (or slots 1 and 3).
 
The specs on the Adata and Corsair memory are both 9.0-9-9-24 with max voltage 1.65v. There is another memory spec where the sticks differ - tRC is 33 on the Adata and 41 on the corsair.
 
The question because I'm still having some small stability issues. Would there be any difference in the configurations below:
 
Opt a (as currently installed) - a1 4GB; a2 2GB; b1 4GB; b2 2GB
 
Opt b. a1 4GB; a2 4GB; b1 2GB; b2 2GB (corsair in channel a; adata in b)
 
Opt c. a1 2gb; a2 2GB; b1 4GB; b2 4GB (adata in channel a; corsair in b)
 
Opt d. a1 2GB; a2 4GB; b1 2GB; b2 4GB (swap the adata and corsair)
 
Opt e. a2  4GB; b2 4GB (abandon the adata so there isn't any assymetry)

id honestly ditch the 2 2gb sticks of adata and stick with the 8 gigs of corsair. the jump from 8 to 12 gigs really isnt something ur gonna notice unless you do some heavy video editing or something along those lines. What ram exactly did you buy?

Thanks for the note.

This is the memory. XMS3 — 8GB Dual Channel DDR3 Memory Kit

I just saw one post that addressed the 12 GB situation, and the config I have is what the "Best Answer" was. http://www.tomshardware.com/forum/312449-31-12gb-2x4gb-2x2gb-dual-channel-asus-p8p67. But, I've seen other posts that strongly discourage mixing memory types.

Better part of valor would be for me to abandon the DS Adata 4 GB memory, and stick with the new 8 GB Corsair, putting them in the A2-B2 slots the original memory came in.

I hope that if I take the mixed memory out of the equation, I can get my CPU O/C back up. I'm stable at 99.7X42 now - but anything higher and I had periodic episodes where after maybe multiple days of continuous service, the system just powers itself off and auto reboots. Temps were all good at 70 deg C or less under continuous 100% load.
