It totally depends on the motherboard and the CPU. The former has to support ECC in the BIOS to program the integrated memory controller for 64 or 72 bit address width respectively, the latter has to support registered ECC modules.
Checking for ECC is no problem, as it is to be found in the manual, but registered support seems to be no where written down. Rev E6 CPUs all support registered modules, and at least ECC support is mentioned by AMD itself (I read that in a tech review about Rev. E6 CPUs). My 3000+ Newcastle CG doesn't boot at all with reg ECC, so either reg or ECC or both is not supported. Since I have no non-reg ECC DIMMS around I can't test this.

My last hope was a DFI UT-CFX3200, because someone wrote it had ECC support, but the manual lacks any mentioning of this BIOS option. What a pity. Playing with tRef could grant some better results.

8GB of RAM on a s939 is ridonculous... That rocks man!

vladv · Jun 6, 2014

That IS s pretty awesome man!!

Notice that the registered RAM is running at 543MHz. I weakened the timings from 3-3-3-5 to 3-4-4-10, also changed sum subtimings and increased the voltage from 2.75 to 2.8V
Maybe I can get 3.2GHz stable with this memory clocks, which is 533MHz then, pretty awesome for server DIMMs.
CPU temperature might rise to 55-58°C under full load and 1.584V. I am definitely limited by the low voltage. Guess it's time to volt-mod that board. With lower memory speeds and just two DIMMs i might be able to crack 3.3GHz.

IMPRESSIVE!

oh SNAP! an 8 GB 939 posting over 3 ghz

I think someone finally won the internet..

Socket 939 STILL rullz!

I wonder if we can make some sort of guide to possible compatibility.

I have the same board but, i'll have to see what CPU, maybe can point me to the same ram you have?

seaFs · Jun 8, 2014

Thanks guys, I'm trying to push it harder^^

Qimonda HYS72D256320HBR-5-C
2GB,DDR,400,CL3,ECC,Reg

These DIMMs get very hot, even hotter than OCZ Platinum 1GB sticks (TSOP Infineon BE-5) at 2.85V. I haven't seen so much black on a PCB

I really thought about using some aluminium plates to cool the DIMMs. Espesially RAM slot 1 is a problem, because the the CPU heat sink keeps any air flow away from it. I shot the 4 DIMMs at ebay for 20€ + shipping, used condition pulled form some server. There are plenty of that sticks around now.

Funny thing is, the CF-5 chips seem to be the successor of Samsung TCCD/TCC5/UCCC chips, they have higher densitiy and might crack 300MHz.

and this only works with revision E6 chips? is there a way to tell if one has an E6 CPU? What are using for cooling to get those clocks L2N? Phase? Would a clip on ram cooler help cool the ram?

EDIT: if Google that it brings up ddr 333 on ebay.

EDIT: this works better but, be weary i removed "-F-C" off the end for better results,

My board supports ECC. And my CPU is E6.

I am going to find two sticks and see wassup on 4GB RAM to start...

EDIT: Im fairly confident this board maxes at 4GB. Man... 8 would be dope.

seaFs · Jun 9, 2014

Don't give a damn about the 4GB barrier. Asus supports 4GB of RAM on the A8N32, but sill I'm running twice the amount. Abit officially supports 8GB on the AN8-whatsoever-SLI board. Plus I'm pretty sure I could plug in 4x4GB stacked DRAM and it runs with 16GB, at least with 400MHz.
All the socket 940 Opterons have the same die size, transistor count and revision (which, in fact, has become the memory controller revision) as their 939 counterparts. And you can throw ridiculous amounts of RAM onto 940 boards, they just lack overclocking features.

@cdoublejj
I use simple air cooling. IFX-14 on the CPU, mounted directly on the die, and an 80mm fan blowing some air over the dimms. Without that they get so hot, I can't even touch them for longer than a second (temperature > approx. 45°C). With the air flow it's just a bit warmer than my hands. But for some "extreme" volts > 2.9V I'd like to cool the chips, becuase I don't want to loose them^^

My search words are "8gb pc3200r qimonda". The two items above both use Qimonda CF-5 chips and look exactly like my ones. 27$ sounds like a very good price for the RAM.

About CPU revision: Download the tool "CPU-Z", it reads all the information about your CPU and displays it. If you are not sure, you can "validate" your CPU and post the link in here.

ozlay · Jun 9, 2014

wonder if 4gb ddr ecc sticks work

SwishaMane · Jun 9, 2014

Ill see how 2 dimms goes first, then maybe go for 4. Will be interesting.

AAHHH SNAP!!! I got an E6!!!!

Did you go thorugh a bunch of chips till you found one that will do 3.2 ghz or all we all "doing it wrong"?

the ram probably helps with the overclocks iv ran ECC DDR 266 at 400 before with out any issues

The 4400+ at 3GHz is my first dual core. I think I got very lucky when I shot it on ebay in 2009. I started pushing it that hard a year ago, until then it ran at 2.8GHz with 1.5V. Didn't really know what I was doing with it and started to read and test last year. It all began when 4x1Gb of RAM went into my rig and problems with timings and voltages showed up.
Before last years Christmas I shot an Opteron 180 at ebay for a few bucks with the hope that it runs far better as the X2 4400+. Well, it failed. The Opteron runs worse. It hits 3GHz as well, but needs ~1.45V, compared to 1.296V. Both are delidded, bringing temps and voltage down.

Long story short: I did no magic, just buying nothing expensive. It always takes quite a while to find cheap things.

The registered memory seems to help improve the clocks. My Athlon X2 has a weaker memory controller than the Opteron, which can run 4x1GB at CL2, the other one needs CL2.5. But with the registered RAM all the adressing problems are gone, because the memory controller has to contact 2 chips ber DIMM, not 16, thus giving more stable signals. And there is a smalll clock buffer chip that improves signal quality. Unfortunatley there is no data sheet available for this small chip ( CKVF857 ), but I've found a data sheet for CKV857A, stating that it runs up to 250MHz with 2.3-2.7V. Sounds good to me

The registered buffer is a texas Instruments SSF859, also no data sheet hits for this name here, but a similar one seems to be SN74SSTVF16859. Well, that one requires 2.5-2.7V, but I couldn't find any useful information about the save clocks for this chip.

Anyhow, when touching the DIMMs while the system is running the buffer chips get warm, but not hot. Most of the heat is produced by the memory ICs, so the'll have to be cooled first. Bad thing about the DIMMs: the memory chips are a bit higher than the buffer chips. When using RAM heat sinks, this might be a problem.

i assume they are soldered on lids?

seaFs · Jun 10, 2014

They are not soldered. There is some thermal paste between IHS and die. The IHS is glued by some black rubber on the organic plate. You can cut it with a sharp blade (razor blade or box cutter). Tutorials are out there, too, both in text and video form. I recommend to train it a bit with a spare CPU.

Nope, most use TIM like Ivy/Haswell:

This one is an AM2 Brisbane and the pic ain't mine, I have no delidded A64s right now but I delidded a bunch back in the day.

Delidding an A64 is tricky though, the components beneath the IHS (the little yellow things) are very close to the IHS edge so try on some Athlons you don't mind killing, 939 A64 has less of the yellow things and different spacing/position. And PGA doesn't have an IHS retention bracket like LGA so you'd either have to aim the IHS perfectly on top of the CPU, which is quite complicated, or glue the IHS back on with something.

Well, that or use it without an IHS like in the old days of Athlon Thunderbird. Naked Athlons are very sexy.
