Trying to tune 16 core 62xx ES

tried that still not working. PSU is good, test with other PC. one cpu one stick ram still does the same thing
 
I'm not optimistic on your behalf. As an experienced overclocker that most certainly means dead mobo. However, try putting it in the freezer for a day or so. If that doesn't work, put it in the oven. Don't max the temp, you don't want to melt stuff. I'll ask some guys what they feel is necessary temp wise to attempt to revive HW that way.
 
Tbh I'm not sure, I just know people have done that to for example memory dead sticks with success. I guess it's all about thermal expansion, in some way.
 
Hi guys! I'm a all new member of this forum, but I have been reading here for while (I do fold 24x7 on my i7-980X@4200 + 3xGTX580 = +120K PPD)...

I just ordered 4x 6282SE EngineeringSamples, for my new 4p build, but I'm not sure about what RAM to order:
http://www.alternate.de/html/product/G.Skill/DIMM_8_GB_DDR3-1333_Kit/671932/?
or
http://www.alternate.de/html/product/Crucial/DIMM_16_GB_DDR3-1600_Quad-Kit/1043896/?

To me it seems that 1.35V RAM will only RUN 1333MHz (based on the SM Manual, Page 2-6)...

And will a Noctua NH-U9DO-A3 Cooler be enough to cool the CPU's @+3.5GHz or should I go "Water"? I'll build a Custom Case (150mm tall) with 3x 140mm fans to suck cold air into the case (http://www.alternate.de/html/product/Nanoxia/FX_EVO_140_mm_IFC_-_1500_U-min/1040407/?)

Any input welcome - Only CPU's & Case have been ordered...
 
I am pretty sure all SM and Tyan 4P use 1.5V DIMMs. I think most people are running the G.Skill DDR3-1333 CL7 2GB DIMMs where those are 1.5V.

Personally I would go with a SM board betting that someone smart here update the ONG Custom OCing BIOS to work with ES chips.

Currently I am running CM 212+ with my ES chips. They running about 45C to 50C. I am thinking about switch over to WC to bump the clock rate higher.

I have had great luck with used MountainMod cases. With a tiny bit of work, they house 4P boards nicely.
 
Yeah, with 1.35V, you will get only 1333. For IL chips, I'd recommend DDR3 1600, with the tightest timings you can find at 1.5V.

Noctua 120mm ones would be a better bet, with not much price difference. Water is of course better but much more expensive.

Why not stick with 1.5V? Is there a specific reason you're browsing low voltage memory?

In any way, 1.35V can be reflashed to run at 1.5V (with some effort).

90mm Noctuas will not work for your target speeds. 120mm + fan upgrade (no less than
70 CFM) is reasonable minimum...

Also, you are more likely to run into board issues (current delivery, overheating, et al.) at
the speeds you're shooting for. There are couple cases of killed/damaged boards reported
here due to failure to take necessary precautions.

I would also recommend skipping the case completely (again, given your objectives).

Hi.

It seems that you use a Lian-Li case .

Can you give me the reference of it , please ?
 
Even though I'm in the UK, the best price I found for SM boards in the EU was sona.de. This was a year ago, so it may be worth shopping around to make sure they are still competitive. That being said, they were polite to deal with and shipped pretty quickly.

I am running 6176SEs with a 15% OC using 120mm Noctuas with 5400rpm gentle typhoons. Nothing gentle about those bad boys, but they shift heat. Bear in mind, my system is in a hosting center and the fans just blend in with the background noise. If you run this at home, you *will* notice the fans, so YMMV.

Command rate should be 1 for unbuffered DIMMs. What command rate is TPC reporting?

Re tuning, if you have XMP DIMMs then general mod is this: http://www.amdzone.com/phpbb3/viewtopic.php?f=521&t=138490&p=218810#p218810

Start with basic XMP->JEDEC mod (per amdzone).

Once you exercise that, we can go about forcing 1.5V (if *really* needed).

It is LIAN LI PC-A70F got it on sale for $120.. I have to mod quite a bit to get it to work such as removing top hardrive case and the supporting bracket. Install top rear fan, extending the back board top to support the huge motherboard .. It is very hot if you have internal heatsink so I use external rad to cool the cpus. The internal 4 case fans are only enough to handle the heat from motherboard.

OK.
Command rate isn't covered in the SPD. BIOS comes up with it based on system constraints.
Still, I think it should be using 1T. Are you on 2.0 or 3.0 BIOS? I'm wondering whether it could be a BIOS bug...

Re SPD
Ok, I know which module that is. How many fields would you like to modify and how? (in addition to 1.5V mod)
 
I'm on 3.0 Bios. In the begining I'd like to make Trcd = 7, Access mode 1T and voltage 1.5V .. Ultimately, these are the fields I'd like to mod
Tcl=7 Trcd=8 Trp=7 Tras=24 Access Mode:2T
 
Last edited:
Ok, we won't be able to change access mode without BIOS mod so that's pretty much out (I don't have 3.0 BIOS worked out just yet).
We could, however, report the issue to SM/AMD after double checking that it should be 1T.

Re other fields -- I'll post something in AMDzone in the evening. Will let you know.
 
Thanks tear. It is command mode 2T by gskill manufacture recommended setting. Wonder if I should flash back to V2 .. If you know where I can download V2 Bios
 
Just checked. It is 1T for single rank and 2T for dual rank modules (and your modules are dual rank, unfortunately) -- from AMD BKDG (pub 42301), Table 73 (excerpt):

Code: 
+--------------+---------+-----------+-------+-------+-------+---------------------+
| NumDimmSlots | DdrRate | DdrVDDIO  | DIMM0 | DIMM1 | DIMM2 | SlowAccessMode (2T) |
+--------------+---------+-----------+-------+-------+-------+---------------------+
| 1            | 1600    | 1.5, 1.35 | SR    | -     | -     | 0                   |
| 1            | 1600    | 1.5, 1.35 | DR    | -     | -     | 1                   |
+--------------+---------+-----------+-------+-------+-------+---------------------+

That means V2 BIOS is likely to behave the same way and we need a BIOS mod to change command rate...

EDIT: heh, on second thought, we could modify the SPD and disable one rank. Downside -- you'd end up with half of memory (which should still be enough for FAH).
     We wouldn't need a BIOS mod though.

Really!!! Would time frame drops if I use half of the ram meaning 8 sticks of ram instead .. Or do you mean only using half the capacity in each of the 16 sticks ram. I looking to speed up frame time.
 
The latter -- using half capacity (single rank) of each DIMM.

Would the frame time drop... I would expect it to. How much -- no idea (it hasn't been done before).

What is your exact memory model? (part number)
And follow-up question -- what is the md5sum of _original_ SPD?
 
Cool, it would be nice to try as I don't need all 32G ram
Gskill F3-12800CL7D-4GBECO
md5sum is on the other power down hard drive. I can give tonight when it is power up if you really need it
 
So it's a 2x2GB kit? Hence 4GB in the part number, correct?

No problem. However if you are planning to run 61xx this case is plenty for you. I'm talking for overclock something higher than 2.5ghz only then I have heat issue. But I'm sure if you add more fan to side panel and top. Heat won't be a problem.

Ok, overdoze. I won't be able to test this until very late tonight. If you'd like to proceed, do this:

1. Download, build and install this d3sak: http://darkswarm.org/d3sak-0.6.tar.gz
2. Start with your modified SPD (-m aggressive)
3. Use hex editor (ghex or similar) to change byte at offset 6 from 0x03 to 0x00 (force 1.5V)
4. Use hex editor (ghex or similar) to change byte at offset 7 from 0x09 to 0x01 (disable one rank)
5. Run d3sak -k on the modified file (note that new file will most likely be created)
6. Flash resulting file

I'll try to cover remaining items later. This should get you going wrt forcing 1.5V
and disabling one rank (make BIOS configure 1T timings).

Note that BIOS will not initialize 1.5V modules if there are any 1.35V modules present.
You will have to remove 1.35V modules to test 1.5V-modded modules.

EDIT: after all mods (at my end), output of d3sak -Stj spd 1600 looks like this (note the checksum, supply voltage and rank number):

Anything I should change/re-think, if this system will be running 24x7 @ +3.5GHz (I already have the PSU & SSD)?
 
Two comments from me...

- H8QGL series offer better voltage regulation (this may actually be secondary concern
 given you're using ES chips), are much cheaper, and offer more WC-friendly socket
 configuration

- 2GB per stick is more than enough for a dedicated folder -- you could save some money
 by taking 2GB-stick route (if they're available in your area)
 
Thanks for the input "tear"!

I was planing for the H8QG6-F Motherboard because I will use it for a huge DataBase app in about 6 month (need 512GB RAM for the app), and yes, I'll be using it for folding, but mainly as a TestServer (64GB will be fine for now) - Yes, I know I can't use the RAM I'm buy now, but I can't afford 512GB RAM at the moment...
 
You'll get no Folding advantage whatsoever with the SSD. If the computer will employed as a dedicated Folder, you might as well just use an old, cheap SATA HDD.
 
ubuntu 10.10 booting process is very fast. There is no speed advantage in using different hardrive. Just make sure you have ext3 partition for folding. Other option is to fold in ram. If you are WC and OC to the max get those mosfet heatsinks and fan. I've learned it the hard way.
 
Thanks for the input Linden & overdoze!

I only have 3TB & 4TB HDD's, so I figured I could use the 120GB Vertex3MI I didn't use anymore...

Very good info, "overdoze" - I forgot about them! Do you have any idea where in EU I can get them? How many do I need 6 per CPU = 24pcs?
 
What are the measures here? I'd like to check if I've got some spare sinks I can use... got some alu ones, but depending on the measures maybe i can use some copper, too.
