just do it out side of vogons so we don't all get in trouble.

flupke11, could you let me know what cachechk 7 read/write speeds you get on that SuperMicro P3TDE6? I'm curious how much faster the dual channel memory is.

On a non-overclocked dual Tualatin III-S 1.4 GHz, I get the following in Cachechk7 using CL2 PC133 RAM and a SuperMicro P3TDDE,

Read: 775.2 MB/s
Write: 472.9 MB/s

To use my Cachechk7 settings:
read with this command: cachechk -d -t6
write with this command: cachechk -w -d -t6

EDIT:
Using the MSI Pro266TD Master LR with CL2 DDR RAM, I get,

Read: 725 MB/s | 133 MHz FSB
Write: 396 MB/s | 133 MHz FSB

Read: 777 MB/s | 143 MHz FSB
Write: 424 MB/s | 143 MHz FSB

The results of cachechk on the P3TDE6 (all stock), 2,5 GB of Kingston Ram (2*KVR133X72RC3/256 and 2*KTC-G2/1024), 2 PIII 1.4S.

read: 721,8 MB/s
write: 503,7 MB/s

With only the KTC-G2 2GB kit in it, the read performance drops:

read: 658,7 MB/s
write: 503,7 MB/s

Reseating the chips from Bank 1 to Bank 0 gave identical results.

*edit: as far as I know, the Ram is CL3, this might vouch for the faster read performance in your system?

flupke11,

Thank you for posting these results. I find the write speeds most interesting. I would be very interested to see what extra speed CL2 memory gets you in that board. Unfortunately, you need REGISTERED ECC memory, which is difficult to come by in the CL2 rating. I've never seen it in 1 GB modules for the REG ECC requirement, but some scarce 512 MB modules exist. 256 MB pieces are probably a little easier to find.

Here is the full list of various RAM configurations for the Supermicro P3TDDE

Where did you find your P3TDE6 board? I ask because the faulty board I got came with 2 Coppermine CPUs installed and didn't work when I tried to put Tualatin chips in it. Which didn't make sense because the board only is supposed to work with 512K processors (Tualatins). In the past, or currently, there may be sellers on eBay selling these boards with non-Tualatin chips in it - I would be wary of these auction listings given my outcome. I wonder if the boards were modded to work with Coppermine chips?

I have edited the above post to include results of a PIII-S-1.4 board with DDR memory. As many other benchmarking resources online indicate, there is little-to-no performance enhancement.

For more direct comparison with your P3TDE6 with REG ECC CL3 memory, my Intel SAI2 with 2 GB REG ECC CL3 (2 sticks) gets,

Read: 687.2 MB/s
Write: 396.8 MB/s

...making your write speed of 503.7 MB/s seem pretty impressive. I wonder if the trailing edge of the L2 cache is making its way into the write test. Do you still get 503.7 MB/s if you run the test longer, i.e. -w -d -t10

Hey Feipoa, glad I have been of assistance.

I got the board off a Dutch forum, check www.tweakers.nl. It came with both tualatins installed and the 2 gig of ram. I had the 2*256 lying around, and stuck them in as well. The board has worked without hiccups since I've had it. I paid 50 euro for it, if I remember correctly.

Running cachechk with time 10 still gives me 503.7 MB/s write speed.

BTW, I'm going to get a fully functional Dell Poweredge 1650 this Saturday for 40 euro, so if you want, I might run the same tests on that one (has 2GB of ram as well as the two 1.4 tualli's).

Yes please! Post a motherboard photo if you are able to as well.

OK, got the 1650 blade:

write: 500.2 MB/s

Type of ram: KC1060-IND7 Kingston CL3 (2*1024)

Thanks for posting these results. Does the Poweredge also show an increase in read speed when all 4 memory slots are filled? I presume the Poweredge 1650 is also based on the Intel ServerWorks ServerSet III HE-SL chipset? The main advantage of dual channel PC133 memory seems to be in the write performance. Do you have a Speedsys v4.78 screenshot of both of these systems? I wonder if the MOVE speed is also at an advantage.

I have been having some issues with my SuperMicro P3TDDE when all 4 DIMMs are filled. I keep getting memory errors at the end of Test #5 in Memtest86 v4.20. If only 2 slots are filled, and with any of the pair of the 4 memory modules, it will pass, but with 4 filled DIMMs, it will not. It will sometimes pass when 3 are filled, and sometimes not. It is very peculiar. Each module is 512 MB. I wonder if CL2 is too much for the northbridge to handle for 2 GB of RAM with 4 slots filled. This is disappointing as I was planning on building a working system with this very fast Tualatin. I'll try testing it on CL3 mode and 2 GB to see if it passes Memtest.

Anyone seen this happen before?

EDIT (27 May 2013):
Scratch this edit.

NEW EDIT (28 May 2013)
I replaced two 1000 uF capacitors on this board and now it seems to work fine with 4 sticks of CL2 memory. The faulty capacitors didn't look bulging from a traditional sense, but looked like the top diameter was slightly larger than the others. While I did not check the RC time constant of these caps in a circuit, my LCR meter measured them at 915 uF instead of 1000 uF. The (used) caps I replaced them with are 985 uF.

Attached are the Speedsys images for the SuperMicro P3TDDE with CL2 memory.

I'd be interested in the seeing the first 2 speedsys images for your dual Tualatin setups.

Where do you get your 1.4 GHz Tualatins? Is it safe to get them shipped from China?

First up, the P3TDE6:

Thanks for posting these. The results were not very striking when stacked up against a typical dual Tualatin board with CL2 PC133 memory. There does seem to be marginal gain with memory write and move operations though.

The rather shakey graph on my MMX write graph has me wondering if something related to my CPUs are causing memory failures during Memtest's Test #5. Or maybe some registered ECC memory will solve my issues.

Were you able to run Memtest86 v4.20 through to completion on your P3TD6 board?

What does your Dell Poweredge case look like?

The dell is a standard 1U blade server with room for 3 SCA disks.

Currently running memtest on the Supermicro. No errors.

Dual P3 1400 512kb cache, Asus TR-DLS with intel lan and LSI scsi, 4x 1gb pc133 sdram. It came with 9 18 and 36gb scsi drives + cable, 2x dual port 100mbit nic, and the io shield for 30euro shipped. 1dimm had mem errors but the bios has a option to turn 1 side off the dimm. So its now a single sided 512mb dimm and the side with errors isn't used.

Which of all these boards have support for Dual Channel SDRAM? Do the 6 dimm slot boards have that?

Intel ServerWorks LE-T 3.0 Chipset. I Haven't seen any benchmarks from one of these. Do you have the Cachechk7 results using the above noted commands?

Got two Supermicro blade servers with P3TDEi boards and 2GB ECC. One has 1.2's and the other 1.4's. I've been trying to set aside parts like an updated PCI video card for the 1.4--got an fx 5200 for it. I've been trying to find a usb 1.0 audio solution for it. Creative told me the Extigy will work with usb 1.0 because it can be set to 16-bit @ 44.1kHz output, which is all I want. So far haven't found an extigy for less than $40.

Anyway, work fine with XP, but I'm tempted to try 2000 for speed, and experiment with Ubuntu on the 1.2 system.

Interesting in that there is only one PCI slot, but at least it is PCI-X. I wonder if the Matrox Parhelia 256 PCI-X graphics card will work on the Serverset III HE-SL chipset? The drivers wouldn't install correctly on the ServerSet III LE (Intel SAI2 motherboard) system that I have.

I have a Tyan board with an AGP Pro slot (Socket 604, not 370). Do you know if there are any AGP Pro cards that are good for gaming?
