Yes I read the Article, and Yes of Coarse CAS 2 is going to be Faster than CAS 2.5, and CAS 3.0 When you Are Only Comparing DDR-400 Memory ..I want to see a test Between DDR-400 at CAS 2.0, and DDR-500 or 533, at CAS 3.0 and You will Not see the Gaps that you Do with just DDR-400 againt itself....As you can see be the First Chart on the How it Works Page (That you did not Post) that the Max Bandwith that DDR-400 has when in Dual DDR Configuration is 6.4 GB/SEC, But if you Look at the DDR-533 With CAS 3.0, It Has a Max of 8.4 GB/SEC!!..That is a 25% Increase ...............Sean REILLY875

Possible memory timing problem

Hello, I hope you all can help me. I have been wrestling with this problem for about two weeks and have not been able to fix it.
I recently upgraded my system by adding another gig of memory, setting up a raid array, and adding a X-fi Extreme Music card. Before the upgrade my system ran smoothly for about 10 months. After the upgrade it randomly freezes - the system locks up and won't take any more input from the mouse or keyboard. The only way to recover is to hold the power button down for a few seconds. After that it boots normally and runs perfectly until the next freeze. The freeze can happen at any time, in any application, while the system is idle, or even during bootup. I thought for a long time it was the sound card, but now I suspect my memory timings are off. The problem is, I can't figure out how to adjust them in the BIOS.
My system is this:
CPU: AMD Athalon 64 3500+
Motherboard: K8N Neo2 - Bios 1.B
Memory: 4 sticks of Corair Value Select PC 3200 DDR-400 - 512 meg each
Video: ATI Radon X800 Pro
HD: 2X 74gig Raptors in a raid array (striping)
The only PCI card is the soundcard: Creative X-Fi Extreme Music
Power: Antec Neo Power 480
OS: Windows XP, SP2
I think that's everything, if I am missing something, please let me know. I have run Microsoft's memory test utility overnight, and it has checked out. The memory timing should be 3-3-3-8, but I can't figure out how to set that in the Bios. Also, is there a change I should be making for going from two sticks to four? I don't overclock or anything.
I have been trying to figure this out on my own, but I am coming up short. Any help would be appreciated.
Thanks in advance

Hi Claudius. Welcome to the forum. Here are a few tips that will make it easier for you to get help here. Create a sig as described in the forum rules (hint-use profile button in sign-on screen) which will locate all the info about your system in a convenient place at the bottom of each post like I have. It's the same info about your system that you posted in your first post, but having it there in each post makes everyone's life easier. Also indicate whether you have AMD Venice 3500+ (which I think you have).
Timings terminology. It gets confusing because memory specs are listed in different orders when people refer to them, in bios and in post screen. First number should be cas latency (Tcl). Then Ras# to Cas# delay (Trcd). Then Row Precharge Time (Trp). Min Ras# Active time (Tras) is last number although post screen puts it next to last.
Tcl-cas=3
Trcd=3
Trp=3
Tras=8
That's what bios using serial prescence detect (SPD) should pick up under auto for your ram. I doubt bios detected and used Tras 3 like you thought as it would not boot with Tras 3.
Get CPU-Z online for a great tool that gives you a lot of memory info. It shows a lot of info about your chip too. I suspect timings were detected properly or else your machine would not have booted and run.
After you added more identical memory (corsair value select) your machine apparently booted and ran with 2 gigs of ram, at least that is what appears from your post. Microsoft's memory test said things are good. (Don't know what that test is, and if you really want to test it you should use Memtest available online to make a bootable floppy and test memory for about 1 hour.) However, it sounds like your memory is ok and you have some kind of sound card interrupt (IRQ conflict). Did you disable on board sound in bios since you are using a sound card? Try that if you can. If you still get lockups with onboard sound disabled and sound card working, try removing sound card and seeing whether system still locks up.
Good luck.
Edit- In re-reading your post, it may be that system detected Tras 7 instead of Tras 8. You can manually set tras 8 in the bios if you want to, but use CPU-Z first and check CPU-Z memory tab (to see what system is using) and CPU-Z SPD tab (to see what your ram is telling your system to use). I think you will find both are 3,3,3,8. If not, you can always change Tras to 8 in bios and leave everything else on auto. However, you could also change dramm voltage for memory in bios to 2.7 volts without doing anything any harm and this could help memory if you are really having a memory (as opposed to IRQ conflict) problem.

Monitory does not power up after memory timing changed

(See my sig for spects) I tried changing memory timings to 2-3-3-6. The last thing I tried was mem volt from 2.55 to 2.75 and the TI/T2 Memory timing to T1
I hit save and exit and the computer seem to start but no graphics?. ??? SO I had to flip th PSU switch and when I flipped it back (20 seconds later) the computer seemed to start but still no graphics? I never hit the front power button either?!
I had tweaked some of the other values with no problem earlier today. (tras, CAS delay ect).
One other note: I have had to turn off the computer with the PSU switch since 1.4? BIOS flash I did last year. I read something about RAID Firmware version ? (1 year ago) that came with that BIOS causing hangs ect.
I may use this as an excuse to buy Vista today and start from scratch although I really don't want too.

OK. I reset the CMOS and windows loaded ok but now my RAID +1 array is gone. I see addition HD letters in My Computer now. When I entered bios and change it to NVraid I got a windows error saying it could not load because of missing or corrupt file? I tried a repair but it said it did not work.
I do see the healthy raid array when the system Posts. I did not click the restore optimal defaults yet. Maybe I will have to do that now.

MSI Neo4-F & Athlon64 3700+ E6 1T/2T Memory Timing missing in BIOS

Hi. This is my first post. I need help with my new MSI Neo4-F motherboard. The problem is that 1T/2T Memory Timing is not present in the latest BIOS v.1D. MSI website says that my CPU (San Diego 3700+ E6) is supported by the motherboard but there is no way to control the command rate of the memory thru the BIOS. So far I've been using A64 Tweaker to change command rate to 1T from Windows. Previously I used this CPU with the same memory Kingston KHX3200AK2/1G for another motherboard (MSI Diamond Plus) and I didn't have any problems being able to change the 1T/2T memory timing settings thru the BIOS. I wrote couple of e-mails to MSI TEchnical support but i didn't get a response. Does anyone have any ideas that would help me resolve this issue? Any suggestions will be appreciated. Thanks a lot in advance!

Quote from: BG84 on 05-July-06, 02:57:00
its supposed to be there, i have a 3500+ and a 3800+ and its there, but why does it depend on the cpu if the 1t is there anyway, ?, its there with the 1a 1b 1c and 1d, in dram configuration, second auto put it to manual and 1t, youre supposed to gain a 4% performance, which youre not going to see at all.
Sorry to disagree with your 4% figure but using the 1T setting on the A64s makes a huge difference.
I did a quick check on my current rig using 3dmark 03 and the difference in CPU score was 485 vice 554 making an improvement of over 12%!
I know it's not the best of tests to use for this, but it was quick and points to the "noticable" improvement I've found while doing OC benchmarking with a variety of programs.
Not trying to be argumentative, but I didn't want anybody reading this thread in the future to dismiss the "1T" option as being unimportant.

Lower the RAM's Memory Timing to something Less Aggressive...? MSI KM2M Combo-L

(Not sure where would be the best place to post, so this question is posted here and in the BIOS Thread... If possible, could the Moderators please leave BOTH as to assure a response... I'd appreciate it... Thank You..!!!)
MSI KM2M Combo-L (601-6738-010)
I’m running into some application errors, and the main suggestion is to lower the RAM’s Memory Timing to something Less Aggressive...
The problem with that is I don’t see any option in the MSI KM2M Combo-L Phoenix 6g BIOS...
Basically, I’m trying to “Underclock”... NOT “Overclock”...
Any ideas...??
(I tried “searching” the forums, but I’m not finding anything, other than people asking “Why would you want to do that...??” Those types of responses aren’t very useful...)

Hi
The KM2M Combo L bios under Dram Clock/Drive Control allows some adjustment of the memory timings. I suggest that you run it with the Dram Clock set by Spd (default). If you still have errors, run memtest for a couple of hours to check your memory.

Memory Timing w/K7N2-DELTA-ILSR

How do i set the memory timing? I just bought some Corsair DDR400 memory. I have been readding about memory settings as in timing for them. How do I set them in the BIOS? Plus this memory is the TWINX1024-3200LLPT (low latency) memory and I was use it to its full potential. please help?
AMD XP 2800
MSI K7N2-DELTA
CORSAIR TWINX1024-3200LLPT
Visiontek Geforce 4 TI4600 128 DDR

brink182,
You can leave the memory timings to Auto and the mobo will use the latency programed in the RAM's SPD. Just make sure you have the CPU to RAM Ratio set to 1:1.
Take Care,

P965 (7235) memory timing and CPU-Z 1.36...

There's a problem with memory timing (overclock).
Motherboard: msi p965 neo-f(7235) with bios 1.5
memory: kingmax mars ddr2 667 mhz 4gb (4 * 1 gbytes) base timing 5.5.5.15 at 333 mhz.
and 4.4.4.12 at 266 mhz
Processor: Intel E6600
OS: winxp 32bits
If i set "dram timing" to "manual", the ddr memory frequency is adjustable.
In bios,i set the ddr memory frequency to 667 mhz for a "FSB:Dram" --> "4:5" (320 mhz cpu fsb frequency with 400 mhz ddr memory frequency)
Timing is set to 5.5.5.15 and overclock is 9*320 = 2880 mhz
But cpu-z 1.36 says "dram timing 5.5.5.23"
If i change "dram timing" to "manual" (because i can change ddr memory frequency) and all timings to "auto", cpu-z 1.36 says "dram timing 5.5.5.15"
Ok i know, the memory is out the Specification.
But now timing is set to "4.4.4.12" and i change the ddr memory frequency to "533 mhz".
The "FSB:DRAM" is "1:1" (320 mhz cpu fsb frequency with 320 mhz ddr memory frequency).
Then cpu-z 1.36 says "dram timing 4.4.4.20"
If i change "dram timing" to "manual" and all timings to "auto", cpu-z 1.36 says "dram timing 4.4.4.12"
The question is:
why bios don't respect my choice when i set memory timing ?
Thank you... If you understand what i wrote...

Quote from: NovJoe on 26-August-06, 14:17:48
So there is indeed an advantage gain. CPU-Z needs to do some updates on their software now.
Well, I personally will not try Corecenter myself as it has given too much problems since it's 1st launch.
Corecenter does the job well, but what i said it's just possible ameliorations for perfection
Quote from: Maesus on 27-August-06, 01:32:06
Well, overclocking limit is highly depending on the parts you get, there is no guarantee of reaching your wanted overclocking speed by any part unless special tests and validations have been done on the parts. But no RAM manufacturer has done that... So, it's all depending on your luck!
I know, for the overclocking capability.
My little overclock, is what i thought with this motherboard. this is good for silence and consumption.
But it's just a problem with my memory and voltage more than 2.10 v. I'll do tests later, this is not important. But as i like to know the capability
finally if i have bought this motherboard, there were 4 raisons.
first a good price.
Three pci ports.
A minimum overclocking.
And before all, a mainboard with very good stability.
This is my first msi motherboard
This simple mainboard p965 neo-f does not disappoint me
Thank you with the regulators to help to solve the problems.
And It is nevertheless the best place to speak about it

Using mat with locked memory timing

If you disable the spd setting so the bios does not mess with the timings, can you still benifit from using mat? Seems like all mat does is tighten the memory, but if you lock the timings, what good is mat?

you can still benefit mat.
if you lock the timing that mean you do not want to manually adjust or overlock the memory. mat is another internal thing that the motherboard sort itself out.

Memory timing setting at BIOS not working

hi,
Before I start, this is my PC:
Mobo: MSI X58 Pro-E
BIOS: 8.F
CPU: Intel Core I7 930 (2,8 GHz)
RAM: 2 x (OCZ3P1333LV6GK) 12 GB
Vid: Saphire HD5870 Vapor-X OC Edition
PSU: Ultra LSP750
HDD: WD 1.5 TB 32 MB Buffer 7200 RPM
Chipset: Intel X58+ICH10R
OS: Windows Ultimate 7 64 bit
My system was running ok with 3 DIMMs at 1066Mhz, but now with 12GB I am getting BSODAND and programs are crashing. I noticed that when I try to manually set the timing at BIOS advanced memory setup and reboot, I press F5 (Memory-Z) and the timings are always the same 7-7-7-16 even if I put any other timing at the BIOS menu. Maybe am I missing some other setup? How can I change that timing?

I already did that but with 1.65V at 1066 and 1333MHz. I changed in BIOS but it seems its not really working to change the timing. I try to change at BIOS to 7-7-7-24 8-8-8-24 9-9-9-30.
CPU-Z doesnt work here but I got PC wizard and these are the infos:
Memory Information :
DRAM/FSB Ratio :   8/2
Supported Channels :   Triple
ECC Diagnostic :   Yes - Disabled
CAS Latency (tCL) :   7 clocks
RAS to CAS (tRCD) :   7 clocks
RAS Precharge (tRP) :   7 clocks
Cycle Time (tRAS) :   24 clocks
Row Refresh Cycle Time (tRF...   59 clocks
Command Rate :   2 T
And
Supported Frequencies :   381MHz, 457MHz, 533MHz, 610MHz
CAS Latency (tCL) :   5 clocks @ 381MHz, 6 clocks @ 457MHz, 7 clocks @ 533MHz, 8 clocks @ 610MHz
RAS to CAS (tRCD) :   5 clocks @ 381MHz, 6 clocks @ 457MHz, 7 clocks @ 533MHz, 8 clocks @ 610MHz
RAS Precharge (tRP) :   5 clocks @ 381MHz, 6 clocks @ 457MHz, 7 clocks @ 533MHz, 8 clocks @ 610MHz
Cycle Time (tRAS) :   12 clocks @ 381MHz, 14 clocks @ 457MHz, 16 clocks @ 533MHz, 19 clocks @ 610MHz
Min TRC :   19 clocks @ 381MHz, 23 clocks @ 457MHz, 27 clocks @ 533MHz, 31 clocks @ 610MHz
I am running only 3 DIMMs at the moment so I can use the pc without problem.

Memory timing issues

I have an MSI 6741 motherboard which can handle PC3200 memory according to the info.
I have 2 sticks of 512 Mb PC 3200 ram and the latest BIOS installed.
I have set the memory speed in the BIOS to "max400" and set the timing to the recommended 3-3-8-3 of the manufacturer (confirmed by reading the memory SPD)
When I boot up I see the memory running at 333 mhz, not 400. I get the same results when I use CPUID to check my memory status.
Any idea how to set/force the motherboard to run my memory at the correct speed?
Thanks for the help.

Are you on a newer than 1.3 bios? (for the K8TM-ILSR) I had the same problems with bios versions newer than 1.3 using 1gb of corsair value select and downgrading to 1.3 resolved this at the expense of temperature accuracy

Can wrong memory timing settings cause RAM damage?

Yesterday, I tried some more aggressive memory timings than I have previously been using. The system wouldn't even POST, so I obviously picked settings that were too aggressive. However, it did power up, and it beeped -- continuously.
I used the JBAT jumper to reset the BIOS but it still wouldn't boot.
I even removed the battery for a few minutes, and that didn't help, either.
Finally, a friend suggested pulling the RAM and seeing what happened. Sure enough, when I pulled the RAM stick from slot 2, the system booted just fine.
If I put it back, it won't POST and it beeps.
If I put it in slot 3, the system will POST but Windows won't start.
Did this stick of RAM get damaged, or is the problem with slots 2 and 3 on the motherboard?
(I did power the system off when I used the JBAT jumper.)

Gigabyte Radeon 9200 video card (I'm not into gaming)

Well, I'm totally screwed.
My new RAM arrived today. I put it into Slot 1. The computer wouldn't POST. I moved the stick to Slot 3. The computer turned on briefly, then I heard a pop, and it died. The Power LED on the front remained on.
I think I fried the mobo.
Now I have a couple of important questions for you guys:
1. How can I make sure it's the mobo rather than some other component (I want to replace the right component)?
2. Since the K8N Neo Platinum is essentially unavailable, I thought I'd upgrade to a Socket 939 board and a faster CPU. But if I swap in a Socket 939 board with nForce 4 chipset, will my PC boot, or will it be useless because the drivers on my system are for nForce 3? Will I have to reinstall Windows to get the system working again?
3. Any secret sources of K8N Neo Platinum mobos? That would make my life a lot easier.
Your expertise and advice is very sorely needed!!

MSI KT2 Combo-L Memory Timing Problem

Currently I have two sticks of Kingston 256MB PC3200 CAS3-3-3-8 ram on this motherboard. (Worked in Dual Channel in my P4P800 at 2.5-2-3-5@PC3200)
Running AMD XP2000+, 266FSB
They're rated to perform fine with 2-2-2-6 timing in PC2100 mode...(checked both datasheets and utilities)
I have already set all these in the BIOS with Command Rate = 1T, FastCommand = Ultra, Bank-Interleave = 4 way
Funny thing is, in CPU-Z or other utilities. I'm getting 2-3-3-6...or RAS to CAS delay = 3, RAS Precharge = 3 instead of both being 2.
Is there any way to fix this problem as I want to set the timing as low as possible...
Thanks.

Quote from: me_AMD on 29-January-06, 19:37:06
...CPU-Z is probably reading SPD rather than your BIOS setting...
SPD has 2-2-2-6 at 266MHz...
So i doubt it's just CPU-Z. Even Everest and Sandra report the same thing.
The funny thing is that it wouldn't lower it anymore even tho I chose all the lowest values...On my other AMD machine, I could lower it all to 2-2-2-6. This is the reason I'm asking.

K9N2 Diamond and Memory timing configuration

Hi, were can I find info about the Memory timings thats possible to configure in the BIOS CELL menu ?
The memory installed is the CORSAIR Dominator PC8500C5D mem sticks.
the four familiar timings, CAS tRCD tRP and tRAS is O.K. ofcourse since they are printed on the memory stick one buy's .
But the other timings:
tRTP
tRC
tWR
tRRD
tWTR
tRFC0
tRFC1
tRFC2
tRFC3
Is there a document somewhere to read about these ?
also has anyone used the "SLI-READY Memory" option with any succes ?
after I enable the SLI READY Memory the motherbord fails to boot until i reset the CMOS.
Regards
//Lars

Leave them to Auto.

MS-7125 - memory problem

My K8N Neo4 v1.0 (MS-7125) has worked perfectly with 2 * 256Mb, DDR, 400 CL3 DIMMS since new, just over two years.
I purchased and installed 2 * 512Mb, DDR400 DIMMS - within minutes of loading XP SP2 the machine simply stopped dead without any warning or error message.
I have since tried all combinations of the above pairs of memory and I can run with 512Mb or 1Gb in either of the memory channels without any problem at all (proves the new memory is OK, I think), but as soon as I use both pairs making a total of 1.5Gb the machine hangs within a few minutes of starting XP SP2. It also does not matter into which channel I put each pair, I still get the same problem.
It seems as though these modules do not like each other.
I would be grateful for any ideas or suggestions.
Regards

Quote from: iwaddo on 07-May-07, 23:06:53
The two modules are the same spec but not the same make.
I've slowed the clock from 200 to 166 but looking in the BIOS was unclear what the CMD referred too, can you clarify?
I purchased these modules because the manual implies I can mix module sizes provided I keep to the same size within each channel, would I be better with 4 * 256Mb, would they then run at 200MHz?
Thank you for your help.
"I purchased these modules because the manual implies I can mix module sizes provided I keep to the same size within each channel, would I be better with 4 * 256Mb, would they then run at 200MHz?"
nop, best will be to use 2 memory sticks only.(matched pairs, e.g. Dual CH Kit high performance one is preferred.)
"I've slowed the clock from 200 to 166 but looking in the BIOS was unclear what the CMD referred too, can you clarify?"
yep, from BIOS navigate to "Advanced Chipset Features", then to "DRAM Configuration" then locate "1T/2T Memory Timing" and apply 2T.

Memory upgrade for KM3M-V mobo (aka MS 7061-01S)

Hi, this is my first post. I've read the guidelines and searched for an existing topic but can't find one that quite matches what I want to ask, so I'm posting a new topic - please forgive me I have erred!
I have a TIME Computers desktop (please don't ask why), mobo being a MSI KM3M-V (also known as MS7061-01S), which is based on VIA KM266 chipset. CPU = Sempron 2400+.
I've just installed a new graphics card, an ATI All-in-Wonder 9200SE, with associated drivers and software including Catalyst (which menat I had to instal MS .net framework too). This seems to be working OK but overall speed not great. (Also, for some reason I don't seem to be getting any sound at all, but I expect I can fix that with a bit of trail and error.)
My next step is to increase the memory. Existing memory installed is one 256MB UDIMM module, but I'm aiming to remove it and instal 2 x 1GB UDIMM modules, which I know the mobo can take. Naturally I'm looking to get the maximum available performance (subject to stability considerations), so I'm looking to go for the highest bandwidth/speed the system can take. This is where it gets tricky. Having searched Crucial, Kingston and other memory configurators plus various other tech articles and indeed MSI's own website, I've reached the conclusion that I can select memory in PC2100/ 2700/ etc up to 4000 or even higher provided that the maximum memory chip size (density) does not exceed 128MB.
But I'm not sure about the speed limitation: is there any point in buying DIMMs capable of DDR333 or 400 - will my chipset limit the speed to 266MHz anyway? I'll be grateful for any expert views.

Thanks for the quick reply, Exo. I agree with you 100% that it's best to go for (at least) PC3200 with a view to a likely future upgrade. As I see it, it makes sense to go for the highest spec available at reasonable cost - so I would probably aim for PC4000 rather than 3200. There doesn't seem to be any downside in doing so (provided one is happy to tweak the BIOS where necessary), and even the MSI MOBO spec seems to endorse this view - see bit picked out in red below:
http://www.msicomputer.com/product/p_spec.asp?model=KM3M-V&class=mb
Main Memory
• Supports four memory banks by using two 184-pin DDR DIMMs
• Supports a maximum memory size of 2GB.
• Supports 2.5v DDR SDRAM DIMM
Due to the High Performance Memory design, motherboards or system configurations may or may not operate smoothly at the JEDEC (Joint Electron Device Engineering Council) standard settings (BIOS Default on the motherboard) such as DDR voltage, memory speeds and memory timing.
