Memory settings? Corsair XMS Extreme - Cas Latency: 2-3-2-6 T1

I've been trying to make sense out of the memory settings in the Bios. I read a bunch of posts but I'm still a little confused...
Here is my memory:
2x512Mb DDR400 - Corsair XMS Extreme - Cas Latency: 2-3-2-6 T1
TWINX1024-3200LLPT
on MB: K8T NEO-FIS2R
what should be the settings as well as voltage for this?
bank interleaving
burst length
CAS (CL)
TRCD
TRAS
TRP
right now I have:
CAS: 2
TRCD: 4
TRP 2
DDR Volts 2.65
thanks

I'm running the same memory as you are with a different colored heat spreader, Corsair XMS 3200LL. My system has worked fine from day one with the standard SPD settings that are 2-3-2-6-1T at the default voltage. Unfortunately, Corsair is really hit or miss since all the BH5 chips are gone. Our RAM is built on CH6 chips (assuming v1.2 RAM). There's a great Athlon 64 Special Report on setting RAM timings for the Athlon 64 on Mushkin's website. Luckily, I haven't had to change anything, but the article may help you out.

Memory settings (MS6380)

Hello,
I got a quick question about my memory settings.
I have got 512MB PC2100 DDR (Samsung) and a MS 6380 KT266.
In the bench-program CPU-Z the memory tab states:
Frequency 200MHz, CAS# Latency 2clocks, RAS to CAS 2clocks, RAS Precharge 2clocks, Cycle Time(Tras) 5clocks.
Shouldn't the frequency be 266 MHz ?
This are my RAM related BIOS settings:
Configured SDRAM Timing by : SPD
SDRAM Frequenty : HCLK-33
SDRAM CAS # Latency : 2.5
SDRAM Bank Interleave : disabled
SDRAM 1T Command : disabled
If 200Mhz is normal, could I change these settings anyway to gain performance ?
Thanks in advance.

They're both disabled now.
Hi, SDRAM Bank Interleave can be analogous to RAID-0 your RAM into 2-way or 4-way, to improve RAM performance.
SDRAM 1T Command is to enable SDRAM signal controller to run at 1T rate. When disabled, it's at 2T rate.

DDR 3200 Cas latency Settings

I have 2x256 platinum corsair 3200 Low Latency twinx memory. I changed the latency settings to 2.2.3.6. and my pc is now running faster. Does anyone Know the optimal settings I should be running them at? Also what is the Burst speed in the bios.( This is listed right ofter the cas latency section in the bios. I have a choice of 8 or 4 what should I choose

If your system is running faster-you should be happy. Timings vary from system to system depending on bios version and quality of ram. Ideal settings are 2-2-2-5. In reality this is hard to achieve with stability on a Canterwood/Springdale chipsets-especially in the higher peformance modes (ultraturbo). Also ras to cas seems to be far more stable on these chipsets when set to 3(my gut feeling is that PAT is somehow affecting this setting). Memory manufactures like Mushkin recommend that 6 be used instead of 5 for btter stability and less potential data corruption. Finally from what I remember about burst length 4 is more stable than 8 but 8 allows for more speed. I do not think there is a big drop off when using burst 4 as opposed to 8-you would have to use your own testing. Your settings are fine as long as your system is stable. My one question is how sure of you that what the bios is reporting is what your memory is actually running at. This has been a "known" issue with the various MSI bios's. Use and independant reporting tool such as CPUZ to check the validity of your timings. Also as you tighten your timings it is advisable to raise your Vdimm-2.65-2.80 seems to do the trick-especially if overclocking.

MSI 875P Neo-FIS2R/P4 2.4C/Corsair XMS 3200 Overclock Settings?

Sorry to bother everyone. I'm going to be switching out my Intel 865PERL cause it only offers a 4% overclock, so I'm barerely scratching 2.5Ghz.
Plus, the funky lights on the MSI board will go nice with my all-red lit case. Anyway, back to the matter at hand:
All I've really been able to find online is information geared towards the 865 Neo-FIS2R model and overclocking, plus the stuff on the Corsair XMS PC3200 seems to all be posted prior to JEDEC approving the 3200 standard. So all the overclock info is back when they were using the XMS 3200 with AMD processors and overclocking to reach 400FSB or a bit higher.
I was hoping to get my 2.4C Ghz w/800mhz FSB up to a good 2.7Ghz, maybe even 3.0Ghz. And I want to bump up my DDR as well (I assume I'll have to anyway, and lock my multipliers on the PCI and AGP ports?) I have an ATI Radeon 9700 Pro All-In-Wonder.
I wasn't sure what I should set the DDR to (I have 2x256MB modules that will run in dual-channel)
I use Artic Silver III or 5 Thermal Paste, and I have six case fans (one top blowhole, one side window, two front intake, two rear pushing air out, plus PSU, CPU, northbridge, etc.)
While I've built systems for quite a few years now, I'm fairly new to overclocking and wasn't sure where I should begin? Thanks for any help with settings advice!

Alright, while I wait for the new memory to arrive, I decided to get a headstart on my first overclocking attempts.
I installed the new PSU and set to work. Here is where I ended up:
BIOS SETTINGS
DRAM=333mhz (underclocked 400mhz DDR)
Spread Spectrum=Disabled
CPU Clock=224
AGP/PCI= 67.01/33.50
CPU VCore = 1.5250V
DDR Voltage= 2.50V
AGP Voltage = 1.60V
This setup is stable insofar as it gets my system to boot into windows. I haven't done much else with it as of yet.
If I try a 225 CPU Clock then my system won't boot and I have to clear the CMOS. I tried this with my DDR at 266 and 333 (and it's 400mhz rated and has worked at the speed just fine before, so I don't think it's the Corsair XMS stuff)
Do I need to increase the Voltage to my CPU in order for this to work or is there something else I'm missing? I figured I should be able to get this 2.6 up to 3.0 easy, and was hoping to shoot for somewhere between 3.2 and 3.7 if possible.
My CPU is labeled Malaysia, and I've heard those tend to overclock pretty well. Inside my case the heatsink is cool to the touch, as are my hard drives. Sound Card is a bit warm, but nothing crazy. My ATI card is pretty hot though, although the increase from 66 to 67.01 on the AGP port shouldn't be too bad, and from what I recall this sucker was always hot anyway.

K8N Neo-FSR nForce3 - Corsair XMS memory running at wrong speed

I have a mobo mentioned in the title. The problem is with upgrading the memory - I've recently bought a 1GB memory stick to go with the 2 existing 512kb memory sticks to make up a total of 2GB, the maximum allowed by this mobo.
The problem is if I have all 3 sticks installed i.e. 2GB the memory will only run at 166mhz/DDR333. If I have just the 1GB stick installed it runs at 200mhz/DDR400. If I have the 2 x 512mb sticks installed it runs at 200mhz/DDR400. If I have have the 1GB and 1x512mb stick, either one, in either socket, it runs at 200mhz/DDR400. BUT if I have all 3 sticks installed it only runs at 166mhz/DDR333.
Does anyone know whats going wrong and how to fix it? ??? The memory sticks are all Corsair XMS 3200C2PT 400mhz sticks. The bios version I'm not sure of, I updated the Bios after I built the PC a year and a half ago but I havn't done it since I'm worried about something going wrong (bad flash = dead PC) etc. The stick timings are all 2-3-3-6 I've tried it with the "auto" setting in the Bios and setting the timings manually but the result is the same.

Quote from: Stick on 08-March-06, 17:08:07
you might try different timings on the memory, something like 3-4-4-8. there is technically one way to pass this issue and that is by overclocking. you can OC your CPU till the memory will run at 200mhz (i think FSB should be 240 in this case if i'm not mistaken)
I'm not very up on o/c'ing.. in fact I know next to nothing about it. How would I do that without damaging anything?
Quote from: Apple renegade on 08-March-06, 18:05:33
Not sure about the nForce S754, but the via ones had no way to run on DDR400 using 3 sticks.
Doesn;t it say in the manual ?
It does so here:
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=571
Sorry, where? I can't see any mention of it. According to the manual and on the website it ought to be compatible:

P45 Platinum Optimum memory settings with 2GB Corsair 1066 memory

Hi all,
Looking for some advice on optimum memory settings as I seem to have been getting unstable results from experimenting with settings and the optimum defaults.
My configuration is as follows:
MSI P45 Platinum (V1.0 PCB) (V1.4 Bios)
Intel Dual Core Duo E8500
Corsair TWIN2X2048-8500C5D DDR2-1066 5-5-5-15-2T configured for 2.2v in Bios
Palit 9800GT
2 x Maxtor 1TB HD's
1 x Floppy + Memory card readers
2 x Samsung DL-DVD-DW's
Silverpower SP-400P2C 400W PSU
With the default optimised settings loaded, the system does not book reliably or pass the memory test, in fact memtest86 just hangs when booted
With the Memory configuration set to 1:1.33 (1600:1066) the systems appears to pass the memory tests and windows is relatively stable. Voltage set to 2.2volt with Spead Spectrum disabled.
Is this really the optimum configuration ? as the Adjusted DRAM Frequency reported by the bios is 887 and I was expecting to see 1066.
Any suggestions as how to optimise reliably would be appreciated.
Although I suspect I may have a PSU issue as once booted the system locks when running any 3D games/demo's and it looks liek the 9800GT's need a lot more amps that I thought when putting the system together.
Rgds

First of all, your DDR2 modules are in fact DDR2-800 (they're using overclocked-overvolted DDR2-800 chips).
Sencondly you need to understand how a FSB/DRAM divider works.
Your processor is Intel E8500 and that means a bus frequency of 1333MHz (333MHz quad-pumped).
In your case 1:1.33 means 1.33 x 333 x 2 = 887 MHz for the DDR2 modules.
Set the divider to 1:1.6 if you want the DDR2 modules to run at 1066MHz.
And finally, the "optimum configuration" for max system stability means real DDR2-1066 (7-7-7-20 at 1.8V) or
DDR2-800 (5-5-5-15 at 1.8V).

BUG with Memory CAS-Latency with MSI i848P Neo-LS BIOS

I have a bug with MSI i848P Neo-LS BIOS. I try many MSI i848P with same trouble : the CAS Latency is always set to 2.0 even if the memory is CAS Latency 2.5.
It doesn't depend on PSU or others things (graphics card,...).
Try with Pentium 4C 2.6 or 2.8
But I have just one brand of memory (but many different sticks). Chips reference are VT56DD32M8PC-5 (256 or 512 Mb). This memory are reference as Cas Latency 2.5
If I set memory timings on SPD or manual : same result !!!
If I set memory speed on AUTO or 400 MHz : same result !!!
If I set other timings, then they are save correctly (ie : RAS# precharge set to 3 or 4).
I check timings with latest version of Memtest86+ V1.0 : http://www.memtest.org/
and of course, I get many errors.
The same memory tested on others mobo, give good results.
I try Windows XP installation and I get.... blue screens.
With some memory sticks : I have this message "memory timing too tighly",
if I press F1 to continue: then I get a memory cas latency of 2.5 with memtest86+ and then no error.
I try BIOS revision 1.0 (default) and 1.2: same result !!!
So, as I said before, I think this is a bug with the BIOS. I agree that a BIOS cannot detect correctly all kind of memory, but if you set memory timings manualy, then it must be set as you want ! ?
Any idea...
Thanks

H0 Alex,
You are correct.I have the same problem with my 875p neo lsr on bios 1.9. TH0S 0S B0OS BUG.but everyone says your psu is not enough or your rams isnt on the MSI Memory Compatability List.
why all of rams I try give same result?
MS0 boards works only with 10 or 20 ram.you don't say customer why you use this rams?
why in asus boards many os these rams working properly.This rams isnt on the MSI Memory Compatability List.but working.I try many no name rams and results are very good in all of the tests.
In my opinion MS0 bioses doesnt work good enough.

Check memory cas latency ?

I have a 15" i5 MBP from 2010 (MacBookPro6,2) with 4 gb of 1066 mhz ram at cl 7. I want to upgrade to 8 gb, but the local computer stores here only carry 2x4gb of 1333 mhz ram at cl 9. My calculations show this new memory should be able to run at 1066 mhz with cl 7. I've installed it in my MBP and it's running fine, but is there a way to tell if the MBP is running the new ram at cl 9 or cl 7 ?

I've never seen these questions asked here before, and I think therefore it's safe to say that very few Mac users ever give a moment's thought to the stats you're asking about. As a general rule, if it works, we use it. If it doesn't, we exchange it for something that does.
Most if not all Macs will slow faster-than-spec RAM down to the speed of the specified modules. Your machine is undoubtedly running your RAM at 1066MHz. As for cas latency, who knows? Apple's specs say nothing about that, and never have.
You will usually save a lot of money by buying RAM online rather than from a local store, and you'll usually be able to find the RAM that is specified for your machine.

KTV4 DDR266 memory CAS latency compatability - question

I am planning to upgrade my DDR266 RAM from 512MB to 1GB by adding a 512MB module.
The current module is CL2, but all available upgrades are CL2.5. Supliers all recommend CL2.5 modules. Will I have a problem if I mix CL2 with CL2.5? I have ask a couple of memory suppliers about the CL compatability, but they will not express an opinion.
If there is an issue, I was wondering if setting CAS# Latency in BIOS to CL2.5 will help.

Hello,
You should never mix memory modules that are different.
Yes it can work fine but for optimum performance you must match.
Sometimes both modules will not work together
PC will BSOD a lot
Or it will be ok.
Yes setting the memory timing to CL=2.5 in the BIOS will make the other memory module run at CL=2.5 but there are more timings that just the CAS latency.
All must be the same/old module must be capable of running at new modules timings.
Will the new module be DDR266?
I would recommend you get some new sticks, PC3200 (<will run at 266DDR) 2x512MB and sell the old one.

DRAM Clock Settings and SDram Cas latency

: 8o Just got my KT3 ULTRA 2 Socket A Motherboard. When I turn on the computer, in the POST test it says:
DRAM Clock = 266MHz
SDRAM Cas Latency = 2
I checked the cmos and the latency is set at 2 , but what about the DRAM Clock? Please help for I am a newbie. Thanks

If your CPU is Athlon XP 2700+/2800+, the FSB is 166Mhz, the DRAM frequency is HCLK (166Mhz).
If your CPU is Athlon XP 2600+ and below, FSB = 133Mhz, then HCLK = 133Mhz, HCLK+33 = 166Mhz
If your CPU is older Athlon or Duron, FSB = 100Mhz, then HCLK = 100Mhz, HCLK+33 = 133Mhz, HCLK+66 = 166Mhz.

Mixing Ram with different CAS latencies in K7n2 Delta-L?

I have been using 512mb Kingston Value Ram in my computer, pc3200, with CAS latency of 3.0. I just purchased some Corsair value select 512mb ram pc3200 with CAS latency of 2.5. I know you are not supposed to mix ram with different speeds (like 400 vs. 333) but does it matter if the CAS latencies are different?
I'm running an AMD XP 1800+, K7n2 delta-L, nforce2 motherboard from MSI. Someone at a computer shop told me they tried mixing Kingston 3.0 CAS with Corsair 2.5 CAS, and said his computer wouldn't even post. So I'm wondering if this is an isolated problem, or you will always run into this problem if you mix ram with different CAS latencies.
If anyone has experience with this issue, please share with the board. Thanks!
Chris

The age old question, will the components I bought be compatible ? There are those that have bought identical matching memory that didn't work. In my case, I had an ECS K7S5A that used PC2100 Crucial memory, the sticks neither matched (at one time they did, but one stick died and they sent me the closest thing they had.). Neither of these Crucial sticks was identified by a configurator as being compatible with the K7N2 Delta L that I decided to buy. In the end, not only did both sticks work, but I put them in as single channel mode (ram slots 1 & 2), but later changed the configuration to dual channel mode (ram slots 1 & 3, even 2 & 3). It worked flawlessly in all three configurations. Sorry for the long answer, but in essence, there are no guarantees and your worries will drive you crazy. When memory is mixed, you reduce the likelihood of compatibility, even when you go beyond the recommended products that were specifically identified.
That guy at the computer shop, did he ever indicate or isolate the true reason why the memory wouldn't work ? Maybe, maybe not. I would think with a disparity in memory, the bios is the key to setting the settings for the worst stick of the bunch. Then again, the products you get might overclock to what the better sticks run at. My assumption is that mixed sticks, the bios retards settings to this in "auto" mode. When you force it manually, it may work or it may fail. One thing you oughta know, each and every stick has the manufacturers id encoded onto them at the very least, just like the firmware on other items indicates a manufacturer code and other data that allows these things to be compatible. So know you face that battle going in with any of them. If the bios programming doesn't allow it to work, from that perspective, there'll be problems.

Does Cas Latency really make a difference?

I have a MSI K8N Neo2 setup (AMD64 3500) and I am inquiring if memory latency effects are really noticible or not during heavy gaming or creating home movies for DVD's. Currently, I have two sticks of Corsair Value Select 512MB DDR PC-3200 (VS512MB400). It has a Cas latency of 2.5. Is there any good noticible performance reason, I should trade up and buy some better performing memory. If so, does anyone have a tried and true favorite with the K8N Neo2? Any thoughts? I have never overclocked, I just run at stock speeds. Perhaps the performance gain is not worth the money?
I also have:

Spread Spectrum Modulation was invented to reduce interferences of high order
harmonics of the bus frequency. The theory is that, because every wave form
generates higher order harmonic waves or Obertoene, accumulation of the latter
can result in interference with the original signal.
One way to avoid this problem is to subject the base frequency to a slow (ca 100,000 clock cycles) modulation,
meaning that the FSB varies between e.g. + and - 1% of the nominal value.
In older boards, usually two different settings were available,
either centered around the nominal value or set with the nominal frequency as the maximum (low modulation).
Most current boards employ the centered modulation.
This is, at least, the official version of Spread Spectrum Modulation.
In reality, there are different reasons for its implementation.
With increasing operating frequency, electronic components emit electromagnetic interference signals (EMI).
EMI, on the other hand can cause interferences with other devices and is,
therefore, subject to regulation by the FCC which limits the signal amplitude according to its guidelines.
Any device exceeding the maximum allowable signal strength will not gain
approval by the FCC and can, therefore, not be marketed.
In order to understand the reason for SSM, it is necessary to know how the FCC
tests EMI.
Basically, the testing device is a radio receiver and the testing is done by sweeping
its receiving frequency through the frequency range of interest and measuring the
interference with the video and audio signals. The bandwidth sensitivity of the
measuring device is in the order of about 1 MHz.
If the operating frequency is modulated to spread over a bandwidth of typically
4-5 MHz, the same will happen to the EMI spectrum and,
instead of showing a sharp peak, the spectrum will be spread to a more or less
Gaussian bell shape.
In this case, the amplitude will be, of course, substantially smaller, that is,
in the order of 1/3 - ¼ of the original peak.
The energy, however, will be the same. On the other hand,
the measuring instrument with its bandwidth limited to only 1/4 of the spread will,
consequently, only see 1/3 to ¼ of the EMI.
Therefore, the system will obtain FCC approval even if it exceeds the guidelines.
Recommended Settings
If running at stock setting, enabling Spread Spectrum Modulation (SSM)
may reduce EMI, and cause less interference with wireles communication devices.
Under all conditions, enabling SSM may cause a system to crash.
This is especially true for overclocking, simply because with the high multiplier values employed now, even a 0.5% modulation up and down can cause
differences up to as much as 10 MHz clock speed within one modulation cycle.
In other words, if the CPU is already operating at its limit, increasing the clock
speed by another 10 MHz may be fatal.
Therefore, for any overclocking, SSM should be turned off.
Another side effect of SSM is that it can interfere with the clock generator.
This means that, instead of merely initializing SSM, it is possible to enable FSB settings that were never supported by the manufacturer.
Examples are the Tyan Trinity 400 where disabling SSE results in an actual bus
speed of 90 MHz instead of the selected 117 MHz or the MSI 6309 where FSB settings of up to 200 MHz become available.
The reason is that activating SSM can cancel out the FSB setting since there
can be a pin address overlap on the clock generator chip.
(from lostcircuits.com)
Lets say your CPU is putting out EMI , its all concentrated on one "channel/frequency" on the spectrum.
What spread spectrum does is broaden that out to multiple channels/frequencies so it isn't as "potent" or interupting.
http://www.rojakpot.com/default.aspx?location=8&var1=0&var2=115
This is interesting.
Fsb spread spectrum enabled can cause internet dropouts.

If i can access it in bios i always have it disabled in any computer i'm maintaining.

Corsair XMS 3200 PRO CL2 2-2-5 not recognized

I think now I understand your problem. OK, this is a long known MSI BIOS problem and until now no fix identified. Please leave with it for the MSI BIOS to override your RAM SPD default settings. Anyway, running with MAT enabled will give the same if not faster RAM performance though. Try that out and compare with other boards.

CAS Latency 2 Reverts To 2.5

My RAM is designed for 2.5-3-3-7. I've already changed it to 2.5-3-3-7, but was recommended by someone else with similar memory that I try changing the 2.5 to 2, for more performance. When I set it to 2 it boots and runs fine, but CPU-Z and Memtest86 report it as 2.5 still. The BIOS definitely reports it as 2.
Why?
Is it true that the CAS Latency makes little difference on my system? Why is this?

X48c memory settings?

Just looking at cpu-z and my memory says

fsb:Dram 1:2
cas#8.0
ras #-cas# 8
ras# precharge 8
cycle time 20
refresh cycle time 60

The memory is corsair CM3X2G1333C9 that's 2x2GB=4GB
This is all default setup on the mobo does this seem right. Is the calculation 534x2.5=1335 where 2.5 the divider 1:2
Don't know much about memory stuff!!!!!
Also what settings do you need to alter in the bios to be able to over volt CPU,dram etc as they are all greyed out and not able to change.
Love this site great stuff and even managed to help somebody happy dayz

Little request here How do you upload screen shots as this would be much easier.
You have to upload images elsewhere (e.g. photobucket.com) and then include the links here. Look here for instructions: https://forum-en.msi.com/index.php?topic=90789.0

For DDR3-1333 (= 667 MHz) the FSB/DRAM Ratio needs to be set to 1:2:
333 MHz x 2 = 666 MHz (~DDR3-1333).
