1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 memory sockets and supports Dual Channel
Technology. After the memory is installed, the BIOS will automatically detect the
specifications and capacity of the memory. Enabling Dual Channel memory mode
will double the original memory bandwidth.
The four DDR2 memory sockets are divided into two channels and each channel has two memory
sockets as following:
Channel 0: DDRII_1, DDRII_3
Channel 1: DDRII_2, DDRII_4

Btw, also from your manual (page 5-1):

At least two SATA hard drives (to ensure optimal performance, it is recommended that you use
two hard drives with identical model and capacity).

OK... didn't see your last post.
Colour coding here apparently means 1 + 3 / 2 + 4

OK switch them... still gives me a memory error...

now - according to this

If you have more than one DIMM and you find errors with both, even when you test them one at a time, this suggests that your RAM is probably OK. Either your motherboard is failing, you are using memory timing settings that are too aggressive, or your RAM is not compatible with your motherboard. You can experiment with memory timing settings in your BIOS, which may allow you to use your RAM without errors at a small performance cost. Another thing to check is that you are using the proper voltage setting for your RAM (not all BIOSes let you set this). Please refer to your motherboard manual for information on this topic - HCI Design cannot provide specific recommendations for BIOS settings.

Another potential cause of memory problems is overheating - make sure your machine is well ventilated and try running the test again.

The memory should be fine, because they all tested fine separately.

so. either
mother board is failing
time setting is too aggressive - but I haven't set anything for it.
Not compatible - I don't think this is an issue, though it isn't listen in the compatibility list, the list did say that it is not exhaustive. I also listed other samsung ram
over heating . no real way to monitor ram temps, but everything else seems to run good.

so what can I do at this stage?
edit the timings? no clue how to do that.
switch to dual channel... still gotta look into that. I'll check the bios next to see if I can figure that out. Can't seem to find a manual for the bios.

[seoulguy]

K... apparently dual channel is already enabled. It's automatic. I just need to look closer.

so... what should I do to try to solve the issue?

Timings? Where would I start with that?

[seoulguy]

K,
so with ram timings, do I go with what is on the card itself?

Samsung 2gb 2rv8 pc2-6400u-666-12-e3 so, 6,6,6,12 ?

Or... something like 6,6,6, 45 - 70,000 ?

lol

I'm checking out the listings on the samsung website, and that's what it says for tRAS, 45-70,000.

https://www.samsung.com/global/system/b ... rev102.pdf

It lists the timings on pg 19.


But... if tRAS is = to the sum of the prior three then it should either be 6x3 = 18...
or (tRC - tRAS) x 3 = (60 - 45) x 3, = 15 x 3 = 45

So... 45 looks a lot closer to 45, then 18 does to 12. I'm purely guessing here. I need to reed more on timings.

Edit - just checked out CPU-Z and what it said timings were,... it said timings were 6,6,6,18 also that tRC was 24, and CR was 2T

[seoulguy]

K,

just went through a nother mem test.

set the ram as

1 2008
2 nothign
3 2008
4 nothing

No errors.

I'm going to give the game a run and see if there are any errors. That way, if there are no errors we can narrow the problems down a little more.

Sometimes it helps to set the RAM timings manually. No odd settings, just the standard settings, but putting them manual sometimes works better than "Auto".
In your case: 6,6,6,12 (that is at the RAM's rated 666 Mhz. so without overclock.) Don't touch the other timings, they are read from the modules anyway.
Make sure the RAM volt is set to 1.8 v

So now you are trying only the the two 2008 modules.

[seoulguy]

So...

we know the answer.

It's setting the 4 ram sticks in.

2 sticks with 2008 works perfectly.

they pass both memtest 86 and memtest.

I can also play that demo now without issues.

I guess the only other thing to test would be if i can do the same with the 2010 memsticks. I bet you I can.

So if that's the case, the question is why? Why would there be an issue with running 4 sticks.

I guess after I test out running just the two 2010 sticks I'll go in and try to manually change the sticks.

So you think the 6,6,6,18 timing is wrong then? I'll try 6,6,6,12.

I'm going to send gigabyta an email about the issue, see if this is a known problem, or what they think about a possible solution, as well.

[Blín D'ñero]

Well you can read the RAM's SPD (its timings table), with CPU-Z (freeware, make sure you use the 64-bit one on a x64 OS).

It could be a Gigagbyte issue, but also could be a Samsung RAM issue. It is possible that between 2008 and 2010 production changed. You would only be sure if you could test 4 x 2010 modules and 4 x 2008 modules...

Yes dual channel always enables itself automatic when the motherboard detects the required population in the DRAM slots.
It could be that the old Gigabyte board has trouble with 4 x 2GB high-density modules.

Instead of emailing them, try the Gigabyte community forum for help.

[seoulguy]

I think I may just end up taking it to the shop. The guy I bought it from has a degree in computer engineering.

Is there a way of testing if it's a bus issue?

I tired using only one ram in each. 1 and 2 were fine, 3 and 4 came back with errors. I'm not sure if that's really an error though. I could see why they wouldn't set up 3 and 4 for single ram usage.

[Blín D'ñero]

A bus issue? Why?
Possibly, having 4 slots populated with high density (2GB) modules, require a little more volts than the default 1.8 volts. Try upping to 1.9 v DRAM voltage. You should try and find out (at Samsung support) which is the 'safe upper limit' for your specific Samsung Ram, to know the safe zone for altering the DRAM voltage up or down. It could be that your RAM can safely run upto 2.1 v whereas other have their limit at 2.0 volts (with more they die). The better the RAM suited for overclocking, the more stable it is against higher voltahe, some can still handle 2.4 volts.
But on the other hand there is the motherboard's capability of keeping stable, well-balanced voltage lines. Some boards have much power fluctuation and -leakage. Some tweaker-friendly boards (mine all do) have some finer options in BIOS, and Loadline calibration, all for enhanced stability.
I don't know your board, and i have no experience with AMD based motherboards (except an old one back in 2001), they act different to Intel based.

Thinking that in your case, 2 modules always work, i see two options:
Probability 1: you only need to up the DRAM voltage to 1.9 v.
Probability 2: you should buy another set of 2010 modules so you can try 4 x 2 GB that are identical, and possibly up the voltage to 1.9 v as well.
