that is what im looking at...375.9MHz 5-5-5-18

 

Please read this:

And you will have your answer with regards to the 375MHz DRAM speed. With regards to the DRAM timing, you need to manually set the timing specs as they are high end and as such are beyond the JEDEC DDR800Mhz DRAM specs.

 

Your Motherboard Manual:

 

http://www.ecs.com.tw/ECSWebSite/Products/ProductsDetail.aspx?detailid=659&DetailName=Manual&MenuID=46&LanID=9

Restart your system and enter your BIOS Setup:

Advanced Chipset Features:

 

DRAM Configuration

 

DDRII Timing Item

 

(Trcd) Ras to Cas delay = 5

(Tras) Min Ras Active Time = 15

(Trp) Row precharge time = 5

 

Leave all else alone. I do not see a setting in your motherboard manual for tCL (Cas Latency) so I assume this board will not allow CL to be set.

 

Results?

i seem to be having the same problem here or maybe its right i dont know lol.......this is what im getting in CPU-Z

 

 

Freq= at idle 200.5Mhz

FSB:DRAM= CPU/5

CAS# Latency(TcL)= 5.0 Clocks

RAS# to CAS# Delay(TrCd)= 5 Clocks

RAS# Precharge(TrP)= 5 Clocks

Cycle Time(TrAs)= 8 Clocks

Bank Cycle Time(TrC)= 26 Clocks

Command Rate(CR)= 2T

 

 

And thats what i get after changing what DerekT suggested...

I'll raise my hand and pose a question as well, if I may. I, too, am confused by the 4-4-4-12 vs. 5-5-5-18 values

 

Just tossed another 2G of XMS2-6400 RAM into my machine (ordered them a while ago, but just took them out of the package yesterday) for a total of 4G. As before, POST shows 5-5-5-5-18, but shows 1T (as to be expected). Now, I have done both:

-manually set the mem speed in the BIOS to 4-4-4-12-1T

-change the settings to 'optimal' (I think its called that)

 

The machine will more often than note BSOD with different errors, ranging from "IRQ_IS_LESS blah blah blah" to "something something CACHE". Needless to say, I took the extra 2 sticks out for now........

 

Also of note is when I take out the 2 newly added sticks, they are quite hot to the touch, whereas the original 2 dont seem to be nearly as warm (althought I havent physically taken out the original 2 to really make sure).

 

Have I set something wrong? I'm thinking maybe of setting the timings to 5-5-5-18-1T, raising/lowering the voltage, and/or possibly reducing the mem speed to a lower number (like maybe 700 as opposed to the listed 800 DDR as shown in the BIOS)

 

Edit: Ran Memtest 3.3 on the 2 original sticks for at least one pass. no errors found (running optimal settings in BIOS). I was curious, tho, and looked in the BIOS memory spd settings and there are more values than I thought-TCAS,TRCD,TRP,TRAS,TRC, and Addressing mode. So I guess 4-4-4-12-2T is one value short, eh?

 

Thank you for your reply, its a thankless job that deserves more compliments than complaints IMO......

 

Update: I perused around the FAQ's here and went ahead and manually set the mem speed to 4-4-4-12-5-2T, and set the memory voltage to 2.10. Am now re-running memtest......if that passes after a while I'll try popping in the other 2 identical chips and run memtest again.....

I would set to 2T and 5-5-5-18. Download Memtest86+ Version 1.7 from http://www.memtest.org. Use this program to test.

Multiplier = 9

FSB = 266

DRAM = Unlinked and set to 667Mhz

FSB - Memory Clock Mode: Unlinked

CPU FSB: 266

CPU Multi: 9

DDR FSB: 667

tCL: 5

tRCD: 5

tRP: 5

tRAS: 18

 

Advanced Memory Settings

 

tRRD: Auto

tRC: Auto

tWR: Auto

tWTR: Auto

tREF: Auto

Async Latency: Auto

CMD: 2T

CPU Spread Spectrum: Enabled

PCIE Spread Spectrum: Enabled

MCP PCIE Spread Spectrum: Enabled

SATA Spread Spectrum: Enabled

LDT Spread Spectrum: Enabled

 

CPU Internal Thermal Control: Enabled

Limit CPUID MaxVal: Enabled

Enhanced C1 (C1E): Enabled

Execute Disable Bit: Enabled

Virtualization Technology: Enabled

Enhanced Intel Speedstep Tech: Enabled

LDT Frequency: 5x

 

PCIEX16_1 Frequency (Mhz): 101

PCIEX16_2 Frequency (Mhz): 101

PCIEX16_3 Frequency (Mhz): 101

SPP<->MCP Ref Clock, Mhz: 201

 

Voltages

Vcore = Auto

Vdimm (DRAM Voltage) = 2.1v

1.2v HT: Auto

NB Vcore: Auto

SB Vcore: Auto

CPU VTT: Auto

 

I would personally also set the DRAM to 667Mhz if you are populating all four DRAM banks. Some do get away with full speed, but it has been my experience that these ones usually come back six months or a year later with DRAM errors.

 

So, set to 2T, 5-5-5-18 and 667Mhz and retest with two passes of Memtest86+ V1.7. If it passes, then move to 5-5-5-12 and retest. If that passes, try 4-4-4-12. Set the Optimal to Auto for testing. You need to find a stable baseline rather than "tweak and hope". :)

 

Regarding the temperatures. Different DRAM has different thermals. Please post the entire Model numbers of all DRAM. Download CPU-z http://www.cpuid.com/download/cpu-z-141.zip and post screenshots of the SPD Tab of all modules (1, 2, 3, 4).

Update:

Ran thru 2 tests of memtest 1.7 with no hiccups. So, naturally I did nothing else and booted it up.....lol. I'm on it now. Running great with no misses. Its been in the OS for about 1/2 hr now.

 

There were a few differences in the settings you listed, but I made the best guess as to the equivalents. Here are the screenies you requested. I hope you can view them.....

I'll let it sit and idle while I watch a movie. Hopefully it'll still be up and running

 

All in all, so far so good. Thank you so much DerekT! You've got my machine going far past where I was able to manage!

Well done! You're very welcome. Corsair aims to please. :D: Now all you need to do is use this system and put it through it's paces. Then let us know how it goes :)

ok put them in slots 2 and 4 but it made no change......put them slots 1 and 2 and it now reads Dual but no change in the speed at all.....?

 

The change will not be great until you are doing some heavy work such as Photoshop with large graphic renderings and many saves action saves. Multiplexing Audio <--> Video, etc...

 

Glad to hear that moving the DRAM ahead and back did the trick. :)

So far so good! Running rock solid for about a week now! Thanx again. Alas, I have another question(s) to pose:

 

-Lets say I take out all 4 1G sticks that are in there now, and replace them with just 2 2G sticks (TWIN2X4096-6400C5 G or TWIN2X4096-6400C5DHX). Basically, same amount of RAM, just 2 slots instead of 4.

-What would the recommended timings be? Edit: just looked it up (5-5-5-18)

-Would it be possible to bump up the memory speed to 800? My guess is 'yes'

-Would this configuration make any difference whatsoever performance wise (not intended to be a loaded question....lol)

Your guess is correct :)

Two issues arise here. The first one being that you would find some performance gain but it is not all that great. However, if you were to sell the 4 X 1024 now, when the price is still decent (considering) then you could buy 2 X 2048 for not a great difference. Since you know that your system is capable of populating all four DRAM banks (and some are not), then you will be ready for an additional 2 X 2048 when needed.

 

If that is not an issue, the I would personally not move to the 2 X 2048 since you have found stability. Some do not, and I advise those who are wondering if they can populate all four DRAM banks to purchase 2 X 2048 and forestall the possible issues that may arise.
