Hmmm... I've got an idea.
Can you please do this:
Code: 
sudo dd if=/dev/mem bs=1M of=core32-ng2.rom skip=$((0xffe)) count=2
an send me (mynick@braxis.org) the result.
I wonder whether extraction of the map from your "stored ROM" will give different results...

Absolutely. It will be later this afternoon when "drudge" work is finished. ;)
Any particular state of operation you want the rig to be in when I run this?
Thanks.

Isn't there a BIOS setting to clear NVRAM at boot time? I think I remember seeing that in the stock BIOS. If set, wouldn't that wipe out the OC settings? I don't have an OCNG BIOS loaded so I can't check.

I do know it checks NVRAM at boot but not sure about the clearing function.
 
Apologies if this has been asked before, haven't had a chance to scan the 12 pages I've missed yet.

I'm looking to go with 128GB of RAM on my soon to arrive 4P system, which will require 4 sets of 4x8GB DIMM sets.

Am I basically just looking to get the lowest CAS value 1600MHz memory sticks I can find or are there other criteria I should be looking at as well?

Right now my eyes are on this set:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231569

To me it looks like a solid choice, but I just wanted to double check with all the Supermicro 4P experts here.
 
I think you be charting waters no one else has been before. Most people are running 16 x 1GB DDR3-1333 CL7 G.Skills, with a few running 16 x 2GB DDR3-1333 CL7 G.Skills.
 
Well damn, that's not great. I'm actually a bit surprised no one's done that yet.

Is there anywhere I can find a list of all the supported memory sticks for the SM boards? I can't imagine with everyone here using G.Skill 1333 and 1600 that G.Skill mem of the same speeds would have an issue just from being larger DIMMs.

I guess my main problem here is that I'm not using this really as a folding machine, it's going to be hit with some serious fluid dynamics and generating several TB of data per day.

Ideally I'd have got the 32 DIMM motherboard instead of the 16 so I could push 256GB of memory, but I think 128 will do for now.
 
As far as I know you have to get ECC ram if you want 8GB DIMMs on these boards. The max is 4GB per slot if standard memory is used. Supermicro has a product page for each board that tells you this stuff.

What do you plan on doing with all that memory? 16GB is adequate for folding bigadv. 32GB is overkill. OCing smaller DIMMs is less problematic.

Thanks for that, not sure how I missed that info when I first researched what I'll need for this machine.

Buying ECC memory isn't a problem though as there's barely any price difference anyway. Take a bit of a hit on memory speed is all since the best you seem to be able to buy is 1600MHz @ CAS 11, opposed to the CAS 9 available to non-ECC.

Maybe I'll just keep to smaller data sets for now and pack 64GB of 2400MHz memory into my 3930K machine and leave this 4P at 32GB for now as a raytrace rendering box. I haven't used the 4P yet, but I imagine a 3930K is a far more enjoyable day to day machine with snappier thread speeds and 6gb Sata SSD drives.
 
If you have the memory on order I would still give it a shot. Sometimes mfr marketing doesn't
follow new developments.

Also, what actually lets you use bigger modules is the register, not plain presence of ECC.

That said, you will need registered memory (which happens to _also_ be ECC).

P.S. I know this thread is cool and all, but we really do read new threads too!
 
Hi guys. I just built a (4) 6174 system with H8QGi-F, (4) Noctua NH-U9DO A3's, and 64GB of Crucial Ballistix DDR3 1600 unbuffered non-ecc CL8 [16 pieces of 4gb sticks, sold in 2x4gb kits], and (2) 256GB Crucial M4 [raid 0]

It seems the highest overclock I can get with 0 HT retries is 224. Going to 228 gives me 1 retry a minute, or so. I guess I'd rather have zero so am back to 224. It booted with 230 but the HT retries were numerous. At 232 it wouldn't POST.

I was kind of hoping for more, but oh well, this is fine.

The CPU's at idle are running about 24C and under load (prime test) 34C.

Now, my question. Where can I adjust memory timings? They are reported in the BIOS buy are greyed out, and I can't figure it out.

The memory:
http://www.crucial.com/store/partspecs.aspx?IMODULE=BLT2KIT4G3D1608DT1TX0

1) I am not sure how to obtain the SPD profile to know what speed they will support at slower speeds

2) When running memtest86+ 4.20 w/o the overclock, it reports DDR3 1333 and 9-9-9-24 timings. Isn't this wrong? Crucial ranks it as CL8 @ 1600, wouldn't it be much faster at 1333, and certainly not slower than 1600.

3) When running memtest86 w/the overclock @ 224, it reports DDR3 1066 and 6-6-6-18.

I am thinking it might be able to run CL6 or CL7 with the overclock @ 1333, but I can't figure out how to make the changes.

Thx tear for your fantastic work. I will be using this system for trading, not FAH.
 
What PSU do you have?

Side question: If not Folding, why would you want to overclock a server? (please excuse any ignorance on my part :) )
 
Memory timings are outomatically adjusted with the overclock utility - they are set to the XMP profile timings on boot. You can't manually adjust them with these boards. You also aren't running at 1066 MHz DDR with the overclock - at 224, you are at 1194. TurionPowerControl can't show that, however. Your overclock timings look correct for that memory.

There's an option that would let you run at 1493 (224*1333.33/200); with your memory that would be CL8.
It's not officially supported but has been found to work for several guys here.

To take advantage of it, add 16 at the end of your smocng.sh command line, e.g.
Code: 
sudo ./smocng.sh 224 16
 
I hope to be overclocking a fresh 4P build this weekend.
sudo ./smocng.sh 224 16
Click to expand...

Concerning the above:
a) is that a permanent command?
b) if yes, and if the machine is not stable with 1493 MHZ DDR, how do we undo it?
c) I will be running the recommended G.Skill DDR3 1333 CL7 RAM. What have been users' results overclocking it? Is it good for 1493 without a voltage boost? Does the H8QGi series BIOS - the custom Next Generation BIOS - have memory over voltage options?
 
(a) it's persistent but not permanent :)
(b) reset CMOS
(c) this flag will have no effect on DDR3-1333 memory as it is already limited to DDR3-1333 (per SPD)
 
Important thing to know -- with OC it's never straight 1333 or 1600 (unless your refclock is 250 or 240 16 w/1600 memory).

CL8/1600 will definitely give more performance in any given workload than CL7/1333 (as absolute timings are the same or better).

1600 CL8: cycle time = 1.25ns, thus absolute CL is 1.25ns * 8 = 10ns
1333 CL7: cycle time = 1.5ns, thus absolute CL is 1.5ns * 7 = 10.5ns
1600 CL9: cycle time = 1.25ns, thus absolute CL is 1.25ns * 9 = 11.25ns

So, as you can see, with 1600/CL9 there's no clear advantage on paper (keep
in mind my first paragraph too).
One would need to do run some thorough (hence time consuming) tests.
 
Thanks to this OC guide, the Ubuntu Folding guide, and great people at the [H] IRC, another G34 4P is bulldozing protein models.

Apologies if I left anyone out. It was a bit frenetic for me during the first OC session on IRC with this new Opteron beast.
 
hello all,
I hope any of you can give me some help or advice.
disclaimer; I have limited experience in multi-cpu boards, and bios setups.

I have the following:
H8QGI-F with two 6282SE's Bios 2.0b
2 x 4x4Gb Corsair Vengeance DDR1600 (installed in the A slots)
Windows 7 Pro

the manual states that a minimum of 2 CPU's is required to support full functions. However I'm running an application that supports multi-threading, and it runs way slower then on a system with an intel I7 920 quadcore OC'd at 4Ghz. I see all 32 cores active in task manager. yet when I run CPU-Z, the core speed shows "1400Mhz" on both CPU's, multiplier 7, Busspeed 200Mhz, shouldn't it show 2.6Ghz?
http://screencast.com/t/a8QNGGJaKBmP
Am I missing something?
 
I hope this is not OT but I couldn't find musky's thread on TPC... Just a heads-up:
TPC 0.43 is not working nicely with 6100 Opterons, particularly with voltage setting. So, if you have a processor with which you need to set the voltage when OC'ing, do not use 0.43... Stick with 0.41.

PS: 0.43 is giving an error saying unable to write to, or access to MSR... 0.41 works just fine on the same system.
 
Is this a known bug? If not, you could post in TPC's home thread in the AMDzone...
...and yes, this is OT just as well :D
 
Version 3 ROM for Gi series (only) is now available.

See update in the first post.

GL is in the works.
 
Nice work guys. I will be loading on the current 4P ad new one here this next week.
 
Not sure if downtime is worth it (see update notes; if they don't pertain to your system
then there's no much reason to update).

I don't think so. I think only 1600 CL8 can have measurable advantage over 1333 CL7, and that's only if you use what tear posted in #502.

Hi.
Is anybody know the difference in term of TPF and in percentage between a plateform with DDR3 1279 CL7 and DDR3 1600 cl8 at refclock=240 for example ?
 
If everything is working correctly, this will return 8 rows of 8 "0000" values. If any of these are not "0000", you are getting HT retries. As long as there aren't too many (1 per minute or less), you are fine. If one or more of these numbers are increasing rapidly, you will most likely need to back down your overclock to slow or eliminate them.

After completing a Musky fan mod set for one of my rigs, I am now getting some ht-retries on one value in one row that was not happening before.
I'm trying to decipher which link is at fault here rather than having to remove all 4 CPUs, clean, and re-install. The mod works great but can be difficult with my old fingers. :(
I could not find the thread where the ht-retries "table" was explained, if there is one.
Any help would be appreciated.
